[0002] This application claims priority to Provisional U.S. Patent Application No. 63 / 410,951 filed on September 28, 2022, the entire disclosure of which is hereby incorporated by reference in its entirety. Background Art

[0003] A user environment, such as, for example, a residence or an office building, may be configured using various types of load control systems. A lighting control system may be used to control lighting loads in a user environment. Each load control system may include various control devices, including input devices and load control devices. The load control device may receive a digital message for controlling an electrical load from one or more of the load control devices, the digital message may include a load control instruction. The load control device may be capable of directly controlling the electrical load. The input device may be capable of indirectly controlling the electrical load via the load control device. Examples of load control devices may include lighting control devices (e.g., dimmers, dimmer switches, electronic switches, ballasts, light emitting diode (LED) drivers), electric window treatments, temperature control devices (e.g., thermostats), AC plug-in load control devices, and / or the like. Examples of input devices may include remote control devices, occupancy sensors, daylight sensors, temperature sensors, and / or the like.

[0004] Lamps and displays that use efficient light sources such as light emitting diode (LED) light sources for illumination are becoming increasingly popular in many different markets. LED light sources offer many advantages over traditional light sources such as incandescent and fluorescent lamps. For example, LED light sources may have lower power consumption and longer lifespans than traditional light sources. In addition, LED light sources may be free of hazardous materials and may provide additional specific advantages for different applications. When used for general illumination, LED light sources provide the opportunity to adjust the color (e.g., from white to blue, green, etc.) or color temperature (e.g., from warm white to cool white) of the light emitted from the LED light source to produce different lighting effects. Summary of the invention

[0005] As described herein, a lighting control system (eg, any combination of a system controller, a computing device, a dimmer, a lighting control device, and / or a lighting device) may be configured to generate a presentation.

[0006] Lighting devices and lighting control systems are described herein. A lighting device may include one or more light sources, such as emitters, each of which is configured to emit light (e.g., of different colors). In addition, in some examples, such as using a light emitting diode (LED) driver, the lighting device may not include the emitter (e.g., the emitter may be provided separately). The lighting device may include a load control circuit, such as a driver circuit, which is configured to control the amount of power delivered to each of the one or more emitters. The lighting device may include a communication circuit configured to receive a message. The lighting device may include a control circuit for controlling the driver circuit to control the intensity level and color of the accumulated light emitted by the one or more emitters. The control circuit may be configured to generate a display. For example, the control circuit may be configured to receive display information and auxiliary information from a computing device via the communication circuit in one or more messages. The control circuit may be configured to store the display information and the auxiliary information in a memory (e.g., a non-volatile memory) of the lighting device. The control circuitry may be configured to receive a command to perform a show in a message via the communication circuitry (e.g., a command message that may be different from the one or more messages providing the show information and / or the auxiliary information). The control circuitry may be configured to control the drive circuitry to control the intensity level and the color of the accumulated light emitted from the one or more emitters with respect to time to generate the show. The intensity level and the color of the accumulated light emitted from the one or more emitters may be determined using a function that depends on the show information and the auxiliary information stored in the memory of the lighting device.

[0007] The display information may define a relationship of intensity values ​​over time for a duration of the display and a relationship of color values ​​over time for the duration of the display. For example, the display information is defined by one or more tracks, wherein each track defines a relationship of a characteristic of the light emitted from the one or more emitters over time, and wherein the characteristic of the light includes an intensity level or a color. For example, one of the one or more tracks may define a correlated color temperature (CCT) value over time. A track in the one or more tracks may define an x ​​chromaticity coordinate value over time and a y chromaticity coordinate value over time. A track in the one or more tracks may define a red value over time, a green value over time, and a blue value over time.

[0008] The control circuitry may be configured to control the drive circuitry to control the intensity level and the color of the accumulated light emitted from the one or more emitters at a plurality of different times during the duration of the presentation. The intensity level and the color of the light emitted from the one or more emitters at the plurality of different times during the duration of the presentation may be a function of the presentation information and the auxiliary information stored in the memory.

[0009] In some examples, the displayed function for determining the intensity level and the color of the accumulated light emitted from the one or more emitters is a spline function. For example, the display information received by the control circuit may include one or more breakpoints of the spline function. The control circuit may be configured to use the breakpoints of the spline function included in the display information to generate one or more default trajectories, wherein each default trajectory may define a relationship of a characteristic of the light emitted from the one or more emitters over time, and wherein the characteristic of the light includes an intensity level or a color. For example, the control circuit may be configured to generate one or more corresponding trajectories based on the default trajectory using the auxiliary information stored in the memory.

[0010] The start time of the presentation may be related to the time when the command to perform the presentation is received at the lighting device.

[0011] The auxiliary information may include a duration of the display. In such an example, the control circuit may be configured to control the drive circuit in response to the command to control the intensity level and the color of the accumulated light emitted from the one or more emitters with respect to time to repeat the display at the end of the duration. In some examples, the auxiliary information may include the duration of the display. A change in the duration may affect the frequency of the display (e.g., the flashing may be faster or slower based on different durations). In some examples, the auxiliary information may include a time offset indicating a time delay relative to the start of the reception of the command by the lighting device to be applied to the display. In some examples, the auxiliary information may include an intensity adjustment value associated with the display, and the display information may indicate a default intensity level. In such an example, the control circuit may be configured to adjust the default intensity level based on the intensity adjustment value. In some examples, the auxiliary information may include a color shift indicating a change in the color defined by the display information.

[0012] The auxiliary information may be specific to the lighting device, such that different auxiliary information is provided to at least one other lighting device.

[0013] The control circuit may be configured to retrieve the show information and the auxiliary information from the memory of the lighting device in response to the command, and thereafter control the drive circuit to control the intensity level and the color of the accumulated light emitted from the one or more emitters with respect to time to generate the show.

[0014] The communication circuitry may include wireless communication circuitry and the command is received from the computing device or from a dimmer switch via a wireless signal.

[0015] The lighting device may be configured to be coupled to an alternating current (AC) power source to receive an AC mains voltage, and the control circuit may be configured to perform the display in response to receiving the command to perform the display and based on one or more zero crossings of the AC mains voltage.

[0016] The display information may define predefined lighting content that is stored in a memory of the lighting device prior to receiving the command to perform the display. In some examples, the predefined lighting content may include illumination instructions that cause a plurality of lighting devices to emit light that simulates a cyclic rainbow, simulates flickering candlelight, simulates sunlight shining through a forest canopy, simulates a breathing pattern, or simulates a weather display.

[0017] The control circuit may be configured to adjust the color and / or the intensity level of the light while performing the presentation. For example, the control circuit may receive an adjustment command during the duration of the presentation defined by the auxiliary information, wherein the adjustment command comprises a command to adjust a characteristic of the emitted light, such as the intensity level or the color of the emitted light. The control circuit may be configured to control the drive circuit to adjust the characteristic of the emitted light during the duration based on the adjustment command.

[0018] The display may be defined by a combination of light emitted from a plurality of lighting devices. The default display may be defined by the display information. The corresponding display may be defined by a combination of the display information and the auxiliary information received by the lighting device.

[0019] The control circuitry may be configured to alter a default presentation based on the auxiliary information. The default presentation may be determined based on the presentation information.

[0020] The control circuit may be configured to control the drive circuit to control the intensity level and the color of the light emitted from the emitter over a duration based on the display and the auxiliary information stored in the memory of the lighting device based on receipt of a single command to perform the display.

[0021] In some examples, the control circuitry may be configured to, in response to the command and based on the display information and the auxiliary information stored in the memory, control the drive circuitry to control the intensity level and the color of the light emitted from the one or more emitters during the duration defined by the auxiliary information.

[0022] Examples of lighting control systems are described herein. The lighting control system may include one or more (e.g., multiple) lighting devices (e.g., as described above). The lighting control system may include a computing device (e.g., at least one computer-readable storage medium including executable instructions). The computing device may include a system controller, a smart hub, and / or a user device (e.g., a mobile device such as a smartphone, a tablet computer, etc.). The computing device (e.g., a computer-readable storage medium) may be configured to send presentation information and auxiliary information associated with a presentation to each of a plurality of lighting devices.

[0023] When performing the demonstration, the control circuit of each of the multiple lighting devices can be configured to control the respective driver circuit of the lighting device to control the intensity level and the color of the light emitted from the one or more emitters independently of other lighting devices in the multiple lighting devices.

[0024] The lighting devices may be configured to generate respective corresponding displays, wherein the combination of all corresponding displays may constitute the display. For example, in some examples, the control circuit of the first lighting device may be configured to receive first display information and first auxiliary information from the computing device, and in response to the command and based on the first display information and the first auxiliary information stored in the memory of the first lighting device, control the driver circuit to control the intensity level and the color of the light emitted from the one or more emitters over time as defined by the first display information or the first auxiliary information. The control circuit of the second lighting device may be configured to receive second display information and second auxiliary information from the computing device, and in response to the command and based on the second display information and the second auxiliary information stored in the memory of the second lighting device, control the driver circuit to control the intensity level and the color of the light emitted from the one or more emitters over time as defined by the second display information or the second auxiliary information.

[0025] In addition to and / or as an alternative to multiple lighting devices, the system may include non-lighting devices, such as audio devices. For example, the audio device may be configured to receive presentation information (e.g., audio-specific presentation information) and audio device-specific auxiliary information from the computing device in one or more messages. The audio device may be configured to store the presentation information and the audio device-specific auxiliary information in a memory of the audio device. The audio device may be configured to receive a command to perform a presentation in a message (e.g., the command may be the same command received by the lighting device). The audio device may be configured to control power delivered to one or more speakers of the audio device based on the presentation information and the audio device-specific auxiliary information stored in the memory of the audio device in response to the command.

[0026] The non-lighting device may be configured to receive presentation information (e.g., non-lighting device specific presentation information) and auxiliary information from the computing device in one or more messages. The non-lighting device may be configured to store the presentation information and the auxiliary information in a memory of the non-lighting device. The non-lighting device may be configured to receive a command to perform presentation in a message. The non-lighting device may be configured to control a non-lighting output of the non-lighting device based on the presentation information and the auxiliary information stored in the memory of the non-lighting device in response to the command.

[0041] Figure 1A is a simplified block diagram of an example load control system 100 (eg, a lighting control system). Figure 1A An example of a lighting control system 100 having multiple lighting devices such as at least one smart lighting device (e.g., smart light bulbs 120a, 120b) is depicted. As shown, the smart light bulb 120a can be installed in a ceiling downlight fixture 112, and the smart light bulb 120b can be installed in a tabletop lighting fixture 114 such as a lamp (e.g., a desk lamp). Figure 1AThe illustrated smart bulbs 120a, 120b may include different types of light sources (e.g., incandescent, fluorescent, and / or light emitting diode (LED) light sources). Other examples of lighting devices may include light emitting diode (LED) drivers with dedicated light sources. In addition, although primarily described in the context of lighting devices, the system 100 may include other load control devices, such as a motor drive unit configured to control the position and / or speed of movement of motorized window treatments, a driver configured to control the volume or other characteristics of music or sound emitted by a speaker, and the like.

[0042] The smart bulbs 120a, 120b may be capable of sending and / or receiving wireless communications. For example, the smart bulbs 120a, 120b may each include wireless communication circuitry (e.g., a radio frequency (RF) transceiver) operable to send and / or receive wireless signals such as RF signals 106 using a wireless protocol such as a standard wireless protocol (e.g., such as ZIGBEE, Z-WAVE, THREAD, BLUETOOTH, Bluetooth Low Energy (BLE), WI-FI, or MATTER protocol) or a proprietary wireless protocol such as the CLEAR CONNECT protocol (e.g., CLEAR CONNECT TYPE A and / or CLEAR CONNECT TYPE X protocol). The smart bulbs 120a, 120b may be configured to communicate according to one or more proprietary and / or standardized wireless communication standards. One or more of the smart bulbs 120a, 120b may have advanced features. For example, one or more of the smart light bulbs 120a, 120b can be controlled in response to control instructions (e.g., a digital message) received in a message from another control device to emit light having varying intensity levels and / or colors (e.g., color temperatures, such as correlated color temperature (CCT) and / or other colors).

[0043] The smart bulb 120a can be configured to determine whether to respond to a phase control or digital control message (e.g., from the dimmer 140). For example, the smart bulb 120a can determine that the dimmer 140 is generating a phase control signal (e.g., multiple phase control signals). Alternatively or in addition, the smart bulb 120a can receive a configuration message from the dimmer 140. In response to receiving the configuration message, the smart bulb 120a can determine to control the amount of power delivered to the light source of the smart bulb according to the control message (e.g., wireless control message) received from the dimmer 140.

[0044] The lighting control system 100 may include one or more additional lighting devices, such as a light emitting diode (LED) driver 130 for driving an LED light source 132 (e.g., an LED light engine). The LED driver 130 may be located in or adjacent to a lighting fixture of the LED light source 132. The LED driver 130 may be configured to receive digital messages via the RF signal 106 (e.g., from the system controller 150, the computing device 160, and / or the dimmer 140) and control the LED light source 132 in response to the received digital messages. The LED driver 130 may be configured to communicate according to one or more proprietary and / or standardized wireless communication standards. The LED driver 130 may be configured to adjust the color temperature of the LED light source 132 in response to the received digital messages. An example of an LED driver configured to control the color temperature of an LED light source is described in more detail in commonly assigned U.S. Patent No. 9,538,603, entitled SYSTEMS AND METHODS FOR CONTROLLING COLOR TEMPERATURE, issued on January 3, 2017, the entire disclosure of which is hereby incorporated by reference. The lighting control system 100 may also include other types of load control devices, such as, for example, electronic dimming ballasts for driving fluorescent lamps. In some examples, the load control device can be a device or circuit for controlling an external load (e.g., an LED driver, a dimmer, a switching device for controlling an appliance, a thermostat, etc.). In some examples, the lighting device can be a device including a lighting control device / circuit and a light source (e.g., a controllable lamp (e.g., a smart bulb), a linear lighting device, the internal circuit of a lighting fixture (e.g., an LED driver and one or more dedicated LED light sources), etc.). In some examples, the fixture can be a mechanical housing together with an internal lighting device.

[0045] The lighting device (e.g., the smart bulbs 120a, 120b and / or the LED driver 130) may be configured to control the color temperature (e.g., correlated color temperature (CCT)) of the accumulated light emitted by the lighting device to be equal to the target color temperature T TRGT The lighting device (e.g., control circuitry of the lighting device) may determine how to mix (e.g., the mixing may include lumen values ​​for each emitter circuit) light emitted by multiple (e.g., two) emitter circuits (e.g., LEDs) of the lighting device so that the correlated color temperature of the accumulated light emitted by the lighting device is equal to the target color temperature T TRGT For example, the lighting device can be configured to balance the amount of power delivered by each emitter circuit to generate a target color temperature T TRGT , for example, to balance the mixture of the color temperatures of each emitter and make the color temperature of the accumulated light emitted by the lighting device equal to the target color temperature T TRGT For example, the lighting device may be based on a target color temperature T TRGT, target strength L TRGT and / or a specific correlated color temperature of each emitter circuit to control the magnitude of the corresponding drive current conducted through the emitter circuit to a specific magnitude. For example, the lighting device may be based on a method for generating a target color temperature T TRGT The lighting device may use a table (e.g., stored in a memory) and / or one or more equations to determine the value of the driving current so that the correlated color temperature of the accumulated light emitted by the lighting device is equal to the target color temperature T TRGT Alternatively, the system may send a signal to the lighting device that makes the correlated color temperature of the accumulated light emitted by the lighting device equal to the target color temperature T TRGT The desired lumen value and / or drive current magnitude.

[0046] The lighting control system 100 may include a load control device, such as a dimmer 140, which is electrically coupled in series between an alternating current (AC) power source 102 and a smart light bulb 120a, such that the smart light bulb 120a can receive power from the AC power source 102 via the dimmer 140. Alternatively, in some examples, the dimmer 140 may operate as a remote control device and may not be coupled in series between the alternating current (AC) power source 102 and the smart light bulb 120a. More specifically, when configured as a remote control device, the dimmer 140 may be installed on an existing switch coupled in series between the alternating current (AC) power source 102 and the smart light bulb 120a, may be mounted on a desktop stand or wall, or may be otherwise configured within the lighting control system. The desktop lighting fixture 114 may be plugged into an electrical outlet 116 electrically coupled to the AC power source 102, such that the smart light bulb 120b can receive power from the AC power source 102. Although Figure 1A Although smart light bulbs 120a and 120b are shown in FIG. 1 , any number of non-smart light bulbs and smart light bulbs may be supported in the lighting control system 100 .

[0047] The dimmer 140 may be configured to send messages for controlling the smart bulbs 120a, 120b and / or the LED driver 130 via the RF signal 106. The dimmer 140 may include wireless communication circuitry configured to send and / or receive wireless signals such as the RF signal 106. For example, the dimmer 140 may be configured to send messages to load control devices (e.g., the smart bulbs 120a, 120b and / or the LED driver 130) within the wireless communication range of the dimmer 140 via the RF signal 106. The dimmer 140 may be configured to communicate according to one or more proprietary and / or standardized wireless communication standards.

[0048] The lighting control system 100 may include one or more control devices that are used to control the smart bulbs 120a, 120b (e.g., control the amount of power delivered to the light source of the bulb) and / or non-lighting control devices (e.g., speakers, electric window treatments, etc., as described herein). The smart bulbs 120a, 120b can be controlled substantially in unison, or individually. For example, the smart bulbs can be partitioned so that the smart bulb 120a can be controlled by a first control device and the smart bulb 120b can be controlled by a second control device. The control devices can be configured to turn the smart bulbs 120a, 120b on and off. For example, the control devices can be configured to control the intensity level of each of the smart bulbs 120a, 120b to a low-end intensity level L. LE With high-end strength level L HE The control device may be configured to control the color (eg, color temperature) of the light emitted by the smart bulbs 120a, 120b.

[0049] The dimmer 140 may be configured to respond to user input and generate control instructions (e.g., wired and / or wireless control signals) for controlling the smart bulbs 120a and / or 120b based on the user input. The dimmer 140 may include a toggle actuator 142, a level adjustment actuator 144, and / or a plurality of visible indicators 146. The dimmer 140 may turn the smart bulbs 120a, 120b on and off in response to actuation of the toggle actuator 142, and / or adjust the intensity level of the smart bulbs 120a, 120b in response to actuation of the level adjustment actuator 144. In some examples, the dimmer 140 may adjust the phase angle of the phase control signal in response to actuation of the level adjustment actuator 144 to adjust the intensity level of the smart bulb 120a. The dimmer 140 may generate a phase control signal via various phase control techniques (e.g., a forward phase control dimming technique, a reverse phase control dimming technique, a center phase control technique, a notch phase control technique, and / or a multi-phase control technique). The plurality of lighting indicators 146 may include one or more internal light sources (e.g., LEDs) configured to be illuminated to provide feedback to a user of the smart dimmer 140. Such feedback may indicate, for example, the state of the smart bulbs 120a, 120b (such as whether the light source of the smart bulbs 120a, 120b is on or off), the current intensity level of the smart bulbs 120a, 120b, etc. The feedback may indicate the state of the dimmer 140 itself, such as the power state of the dimmer 140.

[0050] A user may install a smart lighting device (e.g., such as a smart bulb 120a) on a circuit 103 controlled by a dimmer 140. As such, the smart lighting device (e.g., the smart bulb 120a) may include one or more features that are not available when controlled by a load control device. For example, advanced features such as full range dimming, adjustable dimming control (e.g., use of multiple and / or adjustable dimming control curves), color control, and / or other advanced features may not be available when the smart lighting device (e.g., the smart bulb 120a) is controlled by a load control device. The intensity level of the smart lighting device (e.g., the smart bulb 120a) may similarly be controlled by a phase control signal received from the dimmer 140.

[0051] The lighting control system 100 may also include a system controller 150 and / or a computing device 160 (e.g., a mobile device such as a smart phone or tablet computer). The system controller 150 may be configured to send and / or receive communication signals (e.g., RF signals 106). The system controller 150 may be configured to send messages (e.g., digital messages) to the smart bulbs 120a, 120b for controlling the smart bulbs 120a, 120b and / or to the LED driver 130 for controlling the LED light source 132. The system controller 150 may communicate via one or more types of RF communication signals, such as the RF signals 106, using a wireless protocol (e.g., such as a standard or proprietary wireless protocol). The system controller 150 may be configured to communicate according to one or more proprietary and / or standardized wireless communication standards.

[0052] The system controller 150 can be connected to the network 152, for example, via a wired or wireless communication link. The system controller 150 can be configured to communicate messages with a computing device 160 (e.g., a mobile device such as a smart phone or tablet computer) via RF signals 106 sent through the network 152. The system controller 150 can be configured to receive messages including commands for controlling the smart light bulbs 120a, 120b from the computing device 160 via the network 152 and / or send messages via the network 152 for providing data (e.g., status information) to the computing device 160 and / or other external devices.

[0053] The computing device 160 may be configured to send and / or receive communication signals (e.g., RF signals 106). The computing device 160 may be configured to send messages (e.g., digital messages) to the smart light bulbs 120a, 120b for controlling the smart light bulbs 120a, 120b and / or to send messages to the LED driver 130 for controlling the LED light source 132. The computing device 160 may communicate via one or more types of RF communication signals, such as the RF signals 106, using a wireless protocol (e.g., such as a standard or proprietary wireless protocol). The computing device 160 may be configured to communicate according to one or more proprietary and / or standardized wireless communication standards.

[0054] The computing device 160 may be located on the occupant, for example, may be attached to the occupant's body or clothing or may be held by the occupant. The computing device 160 may be characterized by a unique identifier (e.g., a serial number or address stored in a memory) that uniquely identifies the computing device 160. Examples of personal computing devices may include smart phones, laptop computers, and / or tablet devices. Examples of wearable wireless devices may include activity tracking devices, smart watches, smart clothing, and / or smart glasses. In addition, the system controller 150 may be configured to communicate with one or more other control systems (e.g., building management systems, security systems, etc.) via a network.

[0055] The computing device 160 may be configured to send messages to the system controller 150, for example, in one or more Internet Protocol packets. For example, the computing device 160 may be configured to send messages to the system controller 150 over the network 152 and / or via the Internet. The computing device 160 may be configured to send messages to external services over the Internet, and the messages may then be received by the system controller 150.

[0056] The lighting control system 100 may include other types of computing devices coupled to a network, such as a desktop personal computer (PC), a television with wireless communication capabilities, or any other suitable Internet Protocol-enabled device. Examples of load control systems operable to communicate with mobile devices and / or computing devices on a network are described in more detail in commonly assigned U.S. Patent No. 10,271,407, entitled LOAD CONTROL DEVICE HAVING INTERNET CONNECTIVITY, issued on April 23, 2019, the entire disclosure of which is hereby incorporated by reference.

[0057] The operation of the lighting control system 100 may be programmed and configured using, for example, a computing device 160. The computing device 160 may be executable to allow a user to generate system configuration data (e.g., stored in a system configuration database) that may define how the lighting control system 100 works (e.g., how it will work after installation and commissioning). For example, the configuration software may be a graphical user interface (GUI) software that may be run on the computing device 160 as a PC application, a web interface, and / or an application interface. The configuration software may be executed locally on the computing device 160 and / or on the system controller 150. For example, the configuration software may be executed as a local application on the computing device 160 that communicates with the system controller 150, load control devices, lighting devices, and / or other devices of the load control system 100 to work as described herein. In another example, the configuration software may be executed on the system controller 150 and may be displayed on the computing device 160 via a local application (e.g., a browser) for displaying a GUI. Portions of the system configuration data may be stored on the system controller 150, the load control devices, the lighting devices, and / or other devices of the load control system 100.

[0058] The configuration software and / or the system controller 150 (e.g., via instructions from the configuration software) may generate system configuration data, which may include a load control data set (e.g., presentation, auxiliary information, etc.) that defines the operation of the lighting control system 100. For example, the load control data set may include information about the operational settings of different load control devices (e.g., smart light bulbs 120a, 120b, LED drivers 130 for driving LED light sources 132, etc.) of the lighting control system 100. The load control data set may include information about how the load control devices respond to inputs received from input devices. In addition, the system configuration data may include a floor plan of a space and / or building in which the load control system 100 is installed. The system configuration data may include one or more icons that define the location of lighting devices and / or load control devices on the floor plan. In some examples, the configuration software may display the floor plan with icons on a display of the computing device 160, and may be configured to receive user input that allows configuration and / or control of the lighting devices and / or load control devices associated with the icons. Examples of configuration processes for load control systems are described in more detail in commonly assigned U.S. Patent No. 7,391,297, entitled HANDHELD PROGRAMMER FOR A LIGHTING CONTROL SYSTEM, issued on June 24, 2008, and U.S. Patent No. 10,027,127, entitled COMMISSIONING LOAD CONTROL SYSTEMS, issued on July 17, 2018, the entire disclosures of which are hereby incorporated by reference.

[0059] Figure 1B is a diagram of an example load control system 100b for controlling the amount of electrical power delivered to one or more electrical loads from an alternating current (AC) power source (not shown). The load control system 100b may be installed in a load control environment, such as a room 101b of a building. The load control system 100b may include a plurality of control devices configured to communicate with each other via wireless signals (e.g., radio frequency (RF) signals 104b, 105b). For example, the load control system 100b may include a control source device, a control target device, and / or a system controller 140b that may be configured to send and receive RF signals 104b, 105b. The RF signals 104b, 105b may use a proprietary RF protocol, such as a CLEAR CONNECT protocol (e.g., a CLEAR CONNECT TYPE A protocol and / or a CLEAR CONNECT TYPE X protocol as developed by Lutron Electronics Co., Inc.). Alternatively, the RF signals 104b, 105b may be transmitted using a different RF protocol, such as a standard protocol, e.g., WIFI, Bluetooth, Bluetooth Low Energy (BLE), ZIGBEE, Z-WAVE, THREAD, KNX-RF, ENOCEAN RADIO protocol, or one of a different standard or proprietary protocol. Alternatively or in addition, the load control system 100b may include a wired digital communication link coupled to one or more of the control devices to provide communication between the control devices.

[0060] The control devices of the load control system 100b may include a number of control source devices (e.g., input devices operable to send messages in response to receiving user input, detecting an occupied / vacant condition, measuring an ambient light intensity level, etc.) and a number of control target devices (e.g., load control devices operable to receive messages and control electrical loads in response to the received messages). A single control device of the load control system 100b may operate as both a control source device and a control target device. For example, a control source device may be an originating device or an intermediate device that originates a message, and a control target device may be a destination device or an intermediate device to which a message is sent.

[0061] The lighting control system 100b may include one or more lighting fixtures 110a, 110b, 110c, 110d that may be installed in a room 101b (e.g., in a ceiling 102b of the room 101b). Each lighting fixture 110a to 110d may include a lighting load (e.g., an LED light source) and a corresponding lighting control device (e.g., an LED driver, a ballast, a dimming or switching module, or any combination of such devices) for controlling the corresponding lighting load of the lighting fixtures 110a to 110d. The lighting control device may be a control target device configured to control the corresponding lighting load in response to a control instruction received in a digital message.

[0062] The control source device of the load control system 100b can be used to control the lighting fixtures 110a to 110d. The control source device may be an input device configured to transmit a message (e.g., a digital message) to a control target device of the load control system 100b, such as a lighting control device in the lighting fixtures 110a to 110d, via, for example, RF signals 104b, 105b. The control source device may send a message for controlling (e.g., indirectly controlling) the amount of power provided to the lighting load by the corresponding lighting control device in the corresponding lighting fixtures 110a to 110d. The message may include a control instruction (e.g., a load control instruction) or another indication that causes the lighting control device to determine a load control instruction for controlling the corresponding lighting load. The control source device of the load control system 100b may include, for example, a control device such as a remote control device 130b, which may be configured to send a message to the lighting control device in the corresponding lighting fixtures 110a to 110d via the RF signal 104b in response to the actuation of one or more buttons of the remote control device 130b.

[0063] The load control system 100b may include control modules (e.g., sensor devices and / or fixture controllers), such as control modules 124a, 124b, 124c, 124d. The control modules 124a to 124d may each be mounted to the ceiling 102b of the room 101b, adjacent to a corresponding lighting fixture in the lighting fixtures 110a to 110d. The control modules 124a to 124d may each be electrically connected to a corresponding lighting control device in the lighting fixtures 110a to 110d via a corresponding communication link 122a to 122d (e.g., a wired communication link) for controlling the lighting load. The control modules 124a to 124d may include one or more sensors (e.g., sensing circuits) for controlling the lighting load in the corresponding lighting fixtures 110a to 110d. For example, the control modules 124a to 124d may include an occupancy sensing circuit (e.g., which may operate as an occupancy sensor and / or a vacancy sensor) and / or a daylight sensing circuit (e.g., which may operate as a daylight sensor). The control modules 124a to 124d may be control source devices that send digital messages to the respective lighting control devices to which they are connected via respective wired communication links 122a to 122d. The control modules 124a to 124d may also or alternatively be control target devices that receive digital messages from other devices in the system (such as the remote control device 130b or another control source device) (e.g., over a wireless communication link via RF signals 104b, 105b) for controlling the respective lighting control devices to which the control modules 124a to 124d are connected.

[0064] The occupancy sensing circuits in the control modules 124a to 124d may be configured to detect an occupied and / or vacant condition in the room 101b in which the load control system 100b is installed. The control modules 124a to 124d may control the lighting control devices in the corresponding lighting fixtures 110a to 110d in response to the occupancy sensor detecting an occupied or vacant condition. The control modules 124a to 124d may each operate as a vacancy sensor so that a message is sent in response to detecting a vacancy condition (e.g., a message may be sent or not sent in response to detecting an occupied condition). The daylight sensing circuits in the control modules 120a to 120d may be configured to measure the ambient light intensity level in the visible area of ​​the room 101b in which the load control system 100b is installed. The control modules 124a to 124d may control the lighting control devices in the corresponding lighting fixtures 110a to 110d in response to the ambient light intensity level measured by the corresponding daylight sensing circuits.

[0065] The control modules 124a to 124d may each include a memory or other computer-readable storage medium configured to store instructions thereon for execution by control circuitry thereon. Each control module 124a to 124d may store in memory a unique identifier of other devices in the load control system 100b associated with the control module to enable identification of messages from and / or transmission of messages to the associated control device. For example, each control module 124a to 124d may store in memory a unique identifier of a remote control device 130b associated with the control module and thus be configured to respond to messages from the remote control device 130b. Other control variations are possible.

[0066] The control modules 124a to 124d may each include one or more wireless communication circuits for sending and / or receiving messages, for example, via RF signals 104b, 105b. The first wireless communication circuit of each of the control modules 124a to 124d may be configured to communicate on a first wireless communication link (e.g., a wireless network communication link) via RF signal 104b and / or communicate using a first wireless protocol (e.g., a wireless network communication protocol, such as a CLEAR CONNECT protocol and / or a THREAD protocol). The second wireless communication circuit of each of the control modules 124a to 124d may be configured to communicate on a second wireless communication link (e.g., a short-range wireless communication link) via RF signal 105b and / or communicate using a second wireless protocol (e.g., a short-range wireless communication protocol, such as a Bluetooth protocol and / or a Bluetooth low energy (BLE) protocol). The first communication circuit and the second communication circuit may be independent modules, or may be housed in a common module.

[0067] The control modules 124a-124d may each include one or more wired communication circuits for sending and / or receiving signals and / or messages via the corresponding communication links 124a-124d (e.g., wired power / communication links). For example, each control module 124a-124d may use wired communication circuits to transmit messages with the corresponding lighting fixtures 110a-110d via the corresponding communication links 122a-122d. Each of the communication links 122a-122d may be used to provide communication and / or power to / from each of the lighting fixtures 110a-110d. For example, each of the communication links 122a-122d may include, for example, a digital addressable lighting interface (DALI) link or another digital communication link. Each of the communication links 122a to 122d may be used by a corresponding control module 124a to 124d to send a message (e.g., including a command) to a corresponding lighting control device of a corresponding lighting fixture 124a to 124d for turning on and / or off the corresponding lighting load and controlling the intensity level and / or color (e.g., color temperature) of the corresponding lighting load. Each control module 124a to 124d may receive a message (e.g., including feedback information) from the corresponding lighting control device indicating the on / off state, intensity level, and / or color of the corresponding lighting load. In addition, the lighting control device in each of the lighting fixtures 110a to 110d may each receive power from an AC power source (not shown), and may each supply power to the corresponding control module 120a120d via the corresponding communication links 122a to 122d. Although each of the communication links 122a to 122d may be described herein as a single link, each of the communication links 122a to 122d may be composed of multiple links. For example, the lighting control device of each light fixture 110a-110d may provide power to the corresponding control module 124a-124d via a two-wire power bus, while communication between the control module and the lighting control device may be performed using an analog communication link, such as a 0 to 10V control link or another communication link (e.g., an RS 485 digital communication link) that may not provide power. Figure 1B The control modules 124a to 124d are described as including one or more sensors (e.g., sensing circuits) and one or more wireless communication circuits, but the control modules 124a to 124d may also include only one or more wireless communication circuits (e.g., one or more of the control modules 124a to 124d may not include sensors).

[0068] The load control system 100b may include a system controller 140b configured to send and / or receive messages via wired communication and / or wireless communication. For example, the system controller 140b may be configured to send and / or receive RF signals 104b to communicate with one or more control devices (e.g., control source devices and / or control target devices, such as control modules 124a to 124d). The system controller 140b may transmit digital messages between associated control devices that are configured to control another control device or be controlled by another device. The system controller 140b0 may be coupled to one or more wired control devices (e.g., control source devices and / or control target devices) via a wired digital communication link. The system controller 140 may also or alternatively be configured to communicate on a second wireless communication link (e.g., a standard communication link) via RF signals 106b and / or communicate using a second wireless protocol (e.g., a standard communication protocol, such as Internet Protocol (IP) and / or WI-FI protocol). For example, system controller 140b may be configured to send and / or receive messages over a network 108b, such as the Internet, via RF signals 106b.

[0069] The system controller 140b may be configured to send and receive messages between control devices. For example, the system controller 140b may send messages to the control modules 124a to 124d for controlling the lighting loads in the lighting fixtures 110a to 110d in response to messages received from the remote control device 130b (e.g., via the RF signal 104b). The messages may include configuration data for configuring the control devices (e.g., the control modules 124a to 124d) and / or control data (e.g., commands) for controlling the lighting loads in the lighting fixtures 110a to 110d.

[0070] The load control system 100b may be entrusted to implement control of the lighting loads in the lighting fixtures 110a to 110d based on commands for controlling the lighting loads in the lighting fixtures 110a to 110d transmitted from a control device (e.g., a remote control device 130b) to the control modules 124a to 124d. For example, the remote control device 130b may be associated with the control modules 124a to 124d within the lighting fixtures 110a to 110d. Association information may be stored on the association device, which may be used to transmit and identify messages and / or commands at the association device for controlling the electrical devices in the load control system 100b. The association information may include a unique identifier of one or more of the associated devices. The association information may be stored at the control modules 124a to 124d, the system controller 140b, or at other control devices that may be implemented to implement transmission and / or identification of messages between control devices.

[0071] The network device 150b can communicate with the control modules 110a to 110d and / or the system controller 140b for entrusting and / or controlling the control device of the load control system 100b. The network device 150b may include a wireless phone, a tablet computer, a laptop computer, a personal digital assistant (PDA), a wearable device (e.g., a watch, glasses, etc.) or other computing devices. The network device 150b can be operated by a user 152b. The network device 150b can be configured to communicate with the system controller 140b and / or the control device connected by sending and / or receiving via the network 108b using a standard wireless protocol (e.g., via RF signal 106b). In addition, the network device 150b can be configured to communicate directly with the control modules 110a to 110d by sending and / or receiving messages via a short-range wireless communication link (e.g., using RF signal 105b). Additionally, the network device 150b may be configured to send and / or receive beacon signals that may be used to commission the load control system 100b via a short-range wireless communication link (eg, using the RF signal 105b).

[0072] One or more devices of the system (e.g., one or more lighting devices, load control devices (e.g., dimmer switches), non-lighting devices, and / or computing devices, such as a system controller or mobile device) may cause the lighting devices and / or other load control devices to control one or more characteristics of their respective loads in accordance with a show. For example, for lighting devices, the system may cause the lighting devices to control their respective emitters to emit light in accordance with a show. A show may be a combination of changes in light emitted from multiple lighting devices (e.g., and / or sound from one or more speakers, window treatment movement from one or more motorized window treatments, etc.) with respect to time. During a show, each lighting device may be configured to emit light in accordance with its respective corresponding show, and the combination of all corresponding shows may constitute a show.

[0073] As described in more detail below, one or more lighting devices may be configured to receive and store presentation information and / or auxiliary information that may be used, for example, to enable multiple lighting devices to perform a coordinated presentation. The lighting devices may store the presentation information and auxiliary information in a memory (e.g., non-volatile and / or long-term memory) of the lighting devices. The lighting devices may be configured to perform a presentation in response to a command (e.g., a single command). Thus, the lighting devices may perform a presentation without having to transmit discrete instructions from one or more external computing devices.

[0074] The display information may define predefined lighting content that is stored in the memory of the lighting device before receiving the command to perform the display. For example, the predefined lighting content may include illumination instructions that cause the plurality of lighting devices to emit light that simulates a cyclic rainbow, simulates flickering candlelight, simulates sunlight shining through a forest canopy, simulates a breathing pattern (e.g., yoga / meditation / exercise), or simulates a weather display (e.g., cloud movement, lightning, northern lights, night sky, etc.).

[0075] The display information can be defined in the display duration T SHOW The relationship between characteristics of the emitted light (e.g., intensity value and / or one or more color values, such as CCT value, XY chromaticity coordinate value and / or RGB value, etc.) with respect to time. The characteristics of the emitted light may include an intensity value of the emitted light or a color value of the emitted light. The color value of the emitted light may refer to a CCT value of the emitted light, an XY chromaticity coordinate value of the emitted light, and / or an RGB value of the emitted light.

[0076] The auxiliary information may be specific to each lighting device included in the show (e.g., unique to each lighting device). For example, different auxiliary information may be provided to at least one other lighting device that is also configured to generate a show (e.g., illuminate according to the show information). In this way, each lighting device may be configured to generate a corresponding show based on the show information and the received device-specific auxiliary information. A corresponding show may be defined as a combination of the show information (e.g., common to all lighting devices) and the auxiliary information (e.g., which may be specific to each lighting device). In response to receiving a command to perform a show, each lighting device may drive one or more emitters to generate a corresponding show for a duration T based on the show information and the auxiliary information (e.g., a respective corresponding show stored in a memory in each lighting device). SHOW A plurality of lighting devices may generate a display when all of the lighting devices emit light according to their respective corresponding displays at the same time.

[0077] Because the lighting device is able to use the presentation information and the auxiliary information to generate a corresponding presentation, the lighting device may store thereon (eg, in non-volatile and / or long-term memory) the duration T of the presentation. SHOW A plurality of different intensity values ​​relative to time and / or a duration T of presentation SHOW Thus, after receiving the presentation information and / or the auxiliary information, the lighting device does not need to stream, for example, multiple different intensity values ​​and / or color values ​​when performing a presentation.

[0078] The lighting fixtures may be configured to start a show based on receiving a command to perform the show (e.g., the time of receipt). In this way, the start time of the show may be related to the time when the lighting fixture receives the command to perform the show. Therefore, multiple lighting fixtures may be configured to coordinate the start of a show based on a single command received. In addition, each of the multiple lighting fixtures may be configured with show information (e.g., which may be used to generate one or more default shows) and auxiliary information. The auxiliary information may be specific to each respective lighting fixture (e.g., unique to each respective lighting fixture). In this way, each of the multiple lighting fixtures may be configured to emit light with slightly different characteristics (e.g., intensity level, color, etc.) so that the combination of emitted light from all of the lighting fixtures generates a coordinated show.

[0079] Thus, a combination of lighting devices may be configured to generate a lighting scene based on the show information and the auxiliary information. A lighting scene may be a coordinated and choreographed emission of light from multiple lighting devices. A lighting scene may include one or more lighting devices that emit light according to a show (e.g., possibly with different auxiliary information), and in some examples, may include one or more lighting devices that emit light according to static settings (e.g., static intensity levels and / or colors).

[0080] In some examples, the lighting device can be configured to be coupled to an AC power source for receiving an AC mains voltage. In such examples, the lighting device can be configured to perform a display in response to receiving a command to perform a display and based on one or more zero crossings of the AC mains voltage. For example, the zero crossings of the AC mains voltage can be used as a common timing mechanism so that multiple different lighting devices can coordinate the start of a display.

[0081] In some examples, the display information may be defined by one or more tracks (e.g., default tracks). The track may define a characteristic (e.g., a single characteristic) of light emitted from one or more emitters (e.g., an intensity value and / or one or more color values, such as CCT values, XY chromaticity coordinate values, and / or RGB values, etc.) over time. For example, the display information may define a first track that defines a displayed intensity level L over time. SHOW (t). In addition, the presentation information may define one or more other tracks that define color over time (e.g., CCT values, XY chromaticity coordinate values, and / or RGB values). For example, the one or more other tracks that define color over time may include CCT values ​​T over time. SHOW (t). In addition, one or more other tracks defining color over time may include x chromaticity coordinate values ​​x over time SHOW (t) and the y chromaticity coordinate value Y over time SHOW(t). In addition, one or more other tracks defining the color over time may include the red value R over time. SHOW (t), green value G over time SHOW (t) and the blue value B over time SHOW (t).

[0082] In some examples, the trajectory defined by the display information can be generated using one or more functions. One example of a function that can be used to generate a trajectory is a spline function, such as a basic spline function (e.g., a B-spline function). In the case where the segments of the function are connected, the spline function can be a piecewise polynomial function defined by a number of breakpoints (e.g., knots). For example, the display information may include a plurality of breakpoints of the spline function for each trajectory defined by the display information, and the lighting device may be configured to generate a default trajectory (e.g., L based on the breakpoints and using the spline function). SHOW (t), T SHOW (t), [X SHOW (t), Y SHOW (t)]、[R SHOW (t), G SHOW (t), B SHOW (t)], etc.). For example, when a presentation includes multiple lighting devices, the presentation information sent to each of the lighting devices may be the same, so that the lighting devices can generate the same default trajectory for the presentation.

[0083] The lighting fixtures may use the auxiliary information to generate a corresponding display according to a default trajectory determined from the display information. For example, different auxiliary information may be provided to at least one other lighting fixture that is also configured to generate a display (e.g., emit light according to the display information). In this way, a corresponding display may be defined as a combination of display information (e.g., common to all lighting fixtures) and auxiliary information (e.g., which may be specific to each lighting fixture).

[0084] The auxiliary information may include the duration T SHOW , time offset value t OFF , a frequency adjustment value, an intensity adjustment value associated with the presentation, and / or a color shift associated with the presentation. Duration T SHOW The time offset value t may indicate the time length of each track displayed. OFF The time delay that the lighting device should apply to the start of the show relative to receiving the command to perform the show can be indicated. For example, via the time offset value t OFF , a lighting device may be configured to start a presentation at a different time than one or more other lighting devices that are also configured to present in response to a command (e.g., the same command). For example, the intensity trajectory for a corresponding presentation may define an intensity level L over time. CP (t), where L CP(t) = L SHOW (t + t OFF ). The frequency adjustment value may indicate whether the lighting device is to be repeatedly displayed and / or may indicate an adjustment to the frequency of the repeated display of the lighting device. In some examples, the frequency adjustment value may be a frequency adjustment scalar α FREQ , so that the intensity trajectory of the corresponding display can define the intensity level L over time CP (t), where L CP (t) = L SHOW ([α FREQ · f INIT ] · t), and f INIT is the initial frequency of the presentation. The color shift may indicate a change in the color defined by the presentation information.

[0085] The intensity adjustment value may indicate the duration T of the lighting device during control. SHOW The intensity level L of the intensity trajectory over time to be applied when the intensity level of light emitted from one or more emitters is L CP For example, the presentation information may indicate a default trajectory, and the lighting device may be configured to generate an intensity trajectory for the corresponding presentation based on the intensity adjustment value, for example, so that the intensity level of the lighting device is different from the intensity level of light emitted by one or more other lighting devices that are also configured to perform the presentation. For example, the intensity adjustment value may be an intensity adjustment offset L OFF , which can be added to the intensity level L over time indicated by the default display SHOW (t) to generate the intensity level L over time corresponding to the intensity trajectory shown CP (t), for example, L CP (t) = L SHOW (t) + L OFF For example, the intensity adjustment value may be the intensity adjustment scalar L SC , which can be multiplied by the intensity level L over time indicated by the default display SHOW (t) to generate the intensity level L over time corresponding to the intensity trajectory shown CP (t), for example, L CP (t) = L SC ·L SHOW (t).

[0086] Additionally, in some examples, the auxiliary information may include a randomization setting. For example, the control circuitry may use a randomization function to generate a corresponding display based on the randomization setting. For example, when the display simulates the flickering of a candle, simulates sunlight passing through a forest canopy, simulates a weather display, or simulates another random or pseudo-random pattern, the control circuitry may use a randomization function to generate the display to ensure that the lighting devices performing the display are not synchronized with each other. In some examples, the randomization setting may be an on / off setting that indicates whether the lighting device randomizes one or more characteristics (e.g., intensity level, specific color, and / or timing (e.g., time offset or frequency)) of the light emitted (e.g., or the degree of randomization).

[0087] In addition, as described in more detail herein, a user may be configured to adjust characteristics of the emitted light during a presentation (e.g., increase or decrease intensity levels, adjust color, etc.). For example, a user may be configured to adjust characteristics of the emitted light using an actuator of the lighting device and / or via a graphical user interface (GUI) (e.g., of a computing device and / or an external device). The lighting device may be configured to adjust characteristics of the emitted light while the lighting device is performing a presentation (e.g., for a duration T defined by the auxiliary information). SHOW During the duration T of the presentation, an adjustment command (e.g., an intensity level adjustment command, a color adjustment command, etc.) is received. The lighting device may be configured to control a load control circuit (e.g., a driver circuit) of the lighting device to adjust the intensity of the presentation during the duration T of the presentation based on the adjustment command (e.g., and further based on the presentation information and auxiliary information stored in the memory). SHOW The adjustment commands may include commands to adjust the characteristics of the emitted light, such as the intensity level or color of the emitted light, which are to be executed in conjunction with the presentation information and / or the auxiliary information. That is, the adjustment commands may be used to increase or decrease the intensity level and / or change the color of the presentation independently of the presentation information and the auxiliary information. Furthermore, although described in the context of intensity level and / or color, the adjustment commands may indicate adjustments to the start time of the presentation or the frequency of the presentation.

[0088] Computing device 160 and / or system controller 150 may be configured to create, modify, and / or send presentation information and / or auxiliary information to one or more lighting devices. Computing device 160 and / or system controller 150 may be configured to automatically configure multiple different devices using presentation information and / or auxiliary information. In some examples, computing device 160 and / or system controller 150 may be configured to determine presentation information and / or auxiliary information based on load type (e.g., a specific type of lighting device, a type of non-lighting device, etc.). In some examples, a user may be configured to use computing device 160 and / or system controller 150 to modify presentation information and / or auxiliary information.

[0089] In some examples, computing device 160 and / or system controller 150 may number each of the devices configured to generate the display, e.g., through a delegation step and / or based on the location of the device on a communication bus (e.g., where applicable). Computing device 160 and / or system controller 150 may configure auxiliary information based on the number of devices, the location and / or position of the devices, and / or the type of devices configured to generate the display. In some cases, a user (e.g., an installer of lighting control system 100) may assign a location (e.g., within a space or room) and / or a position (e.g., within a sequence of devices) to one or more of the devices, e.g., by moving sequentially between the devices to number the devices in sequence. For example, computing device 160 and / or system controller 150 may use a camera, e.g., during the delegation process, to determine the relative positions of the devices relative to each other.

[0090] In some examples, computing device 160 and / or system controller 150 may perform a position assignment process to assign positions and / or sequences to lighting devices. For example, computing device 160 and / or system controller 150 may assign a different sequence number N to each lighting device. ORDER Alternatively or in addition, the computing device 160 and / or the system controller 150 may assign the same sequence number N to a plurality of lighting devices (eg, two lighting devices). ORDER (e.g., if the lighting devices are within a threshold distance of each other, such as within 6 inches of each other.) Additionally, in some cases, such as when there may be a greater distance between the lighting devices (e.g., when the distance between the lighting devices exceeds a threshold distance), computing device 160 and / or system controller 150 may skip sequence number N. ORDER In such an example, computing device 160 and / or system controller 150 may view the specific sequence number N of each lighting device.

ORDER , the highest sequence number N among the assigned sequence numbers HI and the duration of the display, T SHOW To calculate the time offset t OFF , for example, t OFF = (T SHOW / N HI ) · N ORDER .

[0091] In some examples, computing device 160 and / or system controller 150 may perform assigning location information to lighting devices using the floor plan and an augmented reality (AR) application that provides AR data to computing device 160 and / or system controller 150. For example, computing device 160 and / or system controller 150 may use the floor plan and / or AR data to assign coordinates (e.g., XY coordinates) to the lighting devices. Alternatively or in addition, computing device 160 and / or system controller 150 may use the floor plan and / or AR data to assign sequential numbers and / or time offsets t OFF Assigned to a lighting fixture.

[0092] In some examples, the presentation may be generated based on an animated image (e.g., an animated Graphics Interchange Format (GIF) image). For example, as described herein, a user may select an animated image, and a device (e.g., a control device) may generate presentation information and auxiliary information based on the number of devices, the positioning (e.g., location) of the devices, and / or the type of devices configured to generate the presentation. As described herein, in some cases, each lighting device may be assigned a location (e.g., within a space or room) and / or a position (e.g., within a sequence of devices). Then, based on the positioning and / or position of each lighting device, each lighting device may be assigned auxiliary information.

However, in such examples, the display information may define how the characteristics of the load type of the control device (e.g., the frequency and / or volume of the sound emitted by the speaker, the position of the motorized window treatment, etc.) are displayed over time (e.g., over the duration T of the display). SHOW Similarly, the auxiliary information may define a device-specific adjustment to one or more of the characteristics (e.g., an adjustment to frequency and / or volume). The non-lighting control device may be configured to store the display information and / or the auxiliary information in a memory prior to receiving a command to perform a display. Thus, some systems may include a lighting control device and a non-lighting control device, and a computing device (e.g., a system controller) may be configured to coordinate multiple loads of various types for a display, such as the emission of light, the generation of sound, the movement of one or more objects (e.g., electric window treatments in a space), etc., based on, for example, receiving a command (e.g., a single command).

The communication circuit 434 may be a wireless communication circuit that includes one or more RF or infrared (IR) transmitters, receivers, transceivers, and / or other communication circuits capable of performing wireless communication.

[0120] Although a single communication circuit 434 may be shown, multiple communication circuits may be implemented in the device 430. The device 430 may include a communication circuit configured to communicate via one or more wired and / or wireless communication networks and / or protocols and at least one other communication circuit configured to communicate via one or more other wired and / or wireless communication networks and / or protocols. For example, a first communication circuit may be configured to communicate via a wired or wireless communication link, while another communication circuit may be able to communicate on another wired or wireless communication link. The first communication circuit may be configured to communicate via a first wireless communication link (e.g., a wireless network communication link) using a first wireless protocol (e.g., a wireless network communication protocol), and the second communication circuit may be configured to communicate via a second wireless communication link (e.g., a short-range or direct wireless communication link) using a second wireless protocol (e.g., a short-range wireless communication protocol).

[0121] The control circuit 431 may communicate with one or more input circuits 433 and may receive input from the input circuits. The input circuit 433 may be included in a user interface for receiving input from a user. For example, the input circuit 433 may include an actuator (e.g., a momentary switch that may be actuated by one or more physical buttons) that may be actuated by a user to transmit user input or selection to the control circuit 431. The control circuit may be configured to perform control by sending control instructions indicating actuation on the user interface and / or control instructions generated in response to actuation. The actuator may include a touch-sensitive surface, such as a capacitive touch surface, a resistive touch surface, an inductive touch surface, a surface acoustic wave (SAW) touch surface, an infrared touch surface, an acoustic pulse touch surface, or another touch-sensitive surface configured to receive input (e.g., touch actuation / input), such as a point actuation or gesture from a user. The control circuit 431 of the device 430 may send a control instruction (e.g., data related to a custom dimming curve) in response to actuation or input from a user on the touch-sensitive surface.

[0122] Input circuitry 433 may include sensing circuitry (e.g., a sensor). The sensing circuitry may be an occupant sensing circuit, a temperature sensing circuit, a color (e.g., color temperature) sensing circuit, a visible light sensing circuit (e.g., a camera), a daylight sensing circuit, or an ambient light sensing circuit, or another sensing circuit for receiving input (e.g., an environmental characteristic in the environment of sensing device 430). Control circuitry 431 may receive information from one or more input circuitry 433 and process the information to perform functions as described herein.

[0123] Control circuitry 431 may communicate with one or more output sources 435. Output sources 435 may include one or more indicators (e.g., visible indicators such as LEDs) for providing indications (e.g., feedback) to a user. Output sources 435 may include a display (e.g., a visible display) for providing information (e.g., feedback) to a user. Control circuitry 431 and / or the display may generate a graphical user interface (GUI) generated via software for display on device 430 (e.g., displayed on a display of device 430).

[0124] The user interface of the device 430 may combine features of the input circuit 433 and the output source 435. For example, the user interface may have a button that actuates an actuator of the input circuit 433, and may have an indicator (e.g., a visible indicator) that may be illuminated by a light source of the output source 435. In another example, the display and the control circuit 431 may communicate bidirectionally, as the display may display information to the user and include a touch screen that is capable of receiving information from the user. The information received via the touch screen may be capable of providing the indicated information received from the touch screen as information to the control circuit 431 for performing a function or control.

[0125] Each of the hardware circuits within device 430 may be powered by power supply 436. For example, power supply 436 may include a power supply configured to receive power from an alternating current (AC) power supply or a direct current (DC) power supply. In addition, power supply 436 may include one or more batteries. Power supply 436 may generate a supply voltage V CC To power the hardware in device 430 .

[0126] As described herein, a lighting device (e.g., smart bulbs 120a, 120b and / or LED driver 130) can be configured to control the color temperature (e.g., correlated color temperature (CCT)) of the accumulated light emitted by the lighting device to be equal to a target color temperature T TRGT The lighting device (e.g., the control circuit of the lighting device) may determine how to mix the light emitted by multiple (e.g., two) emitter circuits (e.g., LEDs) of the lighting device so that the color temperature of the accumulated light emitted by the lighting device is equal to the target color temperature T TRGT For example, the lighting device may be based on a target color temperature T TRGT , target intensity level L TRGT and / or a specific color temperature of each emitter circuit to control the magnitude of the corresponding drive current conducted through the emitter circuit to a specific magnitude. For example, the lighting device may control the magnitude of the corresponding drive current conducted through the emitter circuit to a specific magnitude based on the target color temperature T TRGT The lighting device may use a table (e.g., stored in a memory) and / or one or more equations to determine the color temperature of the accumulated light emitted by the lighting device equal to the target color temperature T.TRGT Alternatively, the system may send a signal to the lighting device to make the color temperature of the accumulated light emitted by the lighting device equal to the target color temperature T TRGT The desired lumen value and / or drive current magnitude.

[0127] The lighting device may be configured to adjust the color temperature of the light emitted by the lighting device according to the intensity level. For example, the lighting device may be configured to move toward a target intensity level L TRGT Controls the current intensity level L of the light emitted by the lighting device PRES , the target intensity level range may span the dimming range, for example, at the lower end intensity L LE (e.g., minimum strength, such as about 0.1% to 1.0%) and upper end strength L HE (e.g., maximum intensity, such as approximately 100%), and the lighting device can be configured to move toward the target color temperature T TRGT Adjust the current color temperature T of the accumulated light emitted by the lighting device PRES The target color temperature can range from the cold white temperature T CW (e.g., approximately 3100 K to 6500 K) with warm white temperature T WW (e.g., approximately 1500 K to 3000 K).

[0128] In addition, in some examples, the lighting device can be configured to adjust the light intensity according to the target intensity level L according to the dimming curve. TRGT To control the target color temperature T TRGT In some cases, when configured with certain dimming curves, the lighting device may be configured at a target intensity level L TRGT When the target color temperature T is increased TRGT , and at the target intensity level L TRGT When the target color temperature T is reduced TRGT . Thus, a lighting device may control multiple emitter circuits to control light emitted by the lighting device along an intensity range associated with color temperatures (CCT values) between the emitter circuits, for example, to provide warm dimming, or vice versa (e.g., cool dimming, as described herein).

[0129] Figure 5A5 is a sequence diagram illustrating a process 500 for controlling a lighting device. In process 500, computing device 520 may be configured to send a plurality of discrete instructions to lighting device 530. In response to receiving each discrete instruction, lighting device 530 may control a driver circuit to cause one or more emitters to emit light at a target intensity level and / or a target color as defined by the discrete instruction. Thus, process 500 requires computing device 520 to continuously send (e.g., stream) commands for adjusting the target intensity level and / or target color to lighting device 530 so that lighting device 530 emits light that changes intensity level and / or color over a period of time.

[0130] For example, at 502 in process 500, computing device 520 may 1 The first message is sent to the lighting device 530, the first message including a command for controlling the lighting device 530 to a target intensity level and / or a target color. In response, the lighting device 530 may receive a command indicating a time t 1 The target intensity level and color of the first message, and at 504, the lighting device 530 can control the driver circuit to make one or more emitters of the lighting device 530 at time t 1 The target intensity level and the target color are emitted as indicated by the first message. In process 500, lighting device 530 may temporarily store the target intensity level and the target color indicated by the message in a memory (e.g., when lighting device 530 is controlling the driving circuit according to the target intensity level and the target color indicated by the message). In some examples, lighting device 530 does not need to store the target intensity level and the target color indicated by the message for a long time (e.g., permanently), for example, because the message only includes a subset of the data required to respond to the command.

[0131] At 506, computing device 520 may, at time t 2 A second message (eg, including a command) is sent to lighting device 530, the second message indicating the target intensity level and color. In response, lighting device 530 may receive a signal indicating time t 2 The target intensity level and color of the second message, and at 508, the lighting device 530 can control the driver circuit to make one or more emitters of the lighting device 530 at time t 2 The target intensity level and target color of light emitted by lighting device 530 are emitted as indicated by the second message. Then, lighting device 530 may receive (e.g., stream) multiple messages (e.g., a stream of multiple messages) from computing device 520 to continuously change the target intensity level and / or target color of light emitted by lighting device 530 until, for example, lighting device 530 is no longer instructed to change the target intensity level and / or target color of emitted light.

[0132] For example, at 510, computing device 520 may perform a n A final message (eg, including a command) is sent to lighting device 530, the final message indicating the target intensity level and the target color. In response, lighting device 530 may receive a signal indicating time t n The target intensity level and target color of the final message, and at 512, the lighting device 530 can control the driver circuit to make one or more emitters of the lighting device 530 at time t n The target intensity level and target color are emitted as indicated by the final message. Thus, using process 500, computing device 520 can instruct lighting device 530 to adjust the target intensity level and / or target color of the light emitted by lighting device 530, but in order to do so, lighting device 530 must receive (e.g., stream) multiple different messages from computing device 520. Such a system requires a large communication bandwidth and, in many cases, a dedicated communication channel (e.g., a digital multiplex (DMX) communication bus). In addition, constant communication in such a system can result in delays and / or errors in coordinating the light emitted from multiple different lighting devices.

[0133] Figure 5B 5 is a sequence diagram illustrating a process 550 for controlling a lighting device. The process 550 may be performed by a computing device 570 and / or a lighting device 580. The computing device 570 may be Figure 1A A computing device 160, Figure 1B The computing device 150b and / or Figure 4 The lighting device 580 may be an example of a device 430. Figure 1A The lighting device 100 shown, Figure 1B The lighting fixtures 110a to 110d and / or Figure 3 An example of a lighting device 300 is shown.

[0134] The computing device 570 and / or the lighting device 580 may perform the process 550 to configure the lighting device 580 to emit light in accordance with the display, e.g., utilizing one or more additional lighting devices. Using the process 550, the lighting device 580 may be configured to receive and store display information and / or auxiliary information, which may be used, for example, to enable a plurality of lighting devices to perform a coordinated display. The display information may define predefined lighting content that is stored in a memory of the lighting device prior to receiving the command to perform the display. For example, the predefined lighting content may include illumination instructions (e.g., display information and auxiliary information) that cause the plurality of lighting devices to emit light that simulates a cyclic rainbow, simulates the flickering of a candle, simulates sunlight shining through a forest canopy, simulates a breathing pattern (e.g., yoga / meditation / exercise), or simulates a weather event (e.g., cloud movement, lightning, northern lights, night sky, etc.).

[0135] At 552, the lighting device 580 may receive the presentation information and the auxiliary information from the computing device 570. At 554, the lighting device 580 may store the presentation information and the auxiliary information in a memory (e.g., non-volatile and / or long-term memory) of the lighting device 580. The presentation information may be defined by one or more tracks (e.g., a default track). The track may define a relationship of a characteristic (e.g., a single characteristic) of light emitted from one or more emitters (e.g., an intensity value and / or one or more color values, such as CCT values, XY chromaticity coordinate values, and / or RGB values, etc.) over time. For example, the presentation information may define a first track that defines an intensity level L of a presentation over time. SHOW (t). In addition, the presentation information may define one or more other tracks that define color over time (e.g., CCT values, XY chromaticity coordinate values, and / or RGB values). For example, the one or more other tracks that define color over time may include CCT values ​​T over time. SHOW (t). In addition, one or more other tracks defining color over time may include x chromaticity coordinate values ​​x over time SHOW (t) and the y chromaticity coordinate value Y over time SHOW (t). In addition, one or more other tracks defining the color over time may include the red value R over time. SHOW (t), green value G over time SHOW (t) and the blue value B over time SHOW (t). Therefore, the presentation information may define the duration of the presentation, T SHOW The relationship between one or more characteristics of light emitted from the image (e.g., intensity value, CCT value, XY chromaticity coordinate value, RGB value, etc.) and time.

[0136] In some examples, the trajectory defined by the presentation information may be generated using one or more functions. One example of a function that may be used to generate a trajectory is a spline function, such as a basic spline function (e.g., a B-spline function). Each function (e.g., a spline) may define a time duration T of the presentation. SHOW The relationship between the characteristics of light emitted in the display information and time. For example, the display information may include a plurality of splines, and the lighting device may be configured to generate a default display based on one or more splines. For example, a spline function may be a piecewise polynomial function defined by a number of breakpoints (e.g., knots) when the segments of the function are connected. For example, the display information may include a plurality of breakpoints of the spline function for each trajectory defined by the display information, and the lighting device may be configured to generate a default trajectory (e.g., L based on the breakpoints and using the spline function. SHOW (t), T SHOW (t), [X SHOW(t), Y SHOW (t)]、[R SHOW (t), G SHOW (t), B SHOW (t)], etc.). For example, when a presentation includes multiple lighting devices, the presentation information sent to each of the lighting devices may be the same, so that the lighting devices can generate the same default trajectory for the presentation.

[0137] The auxiliary information may be specific to lighting device 580. For example, different auxiliary information may be provided to at least one other lighting device that is also configured for the presentation (eg, to illuminate according to the presentation information). The auxiliary information may include a duration T SHOW , time offset value t OFF , frequency adjustment value and / or intensity adjustment value associated with the presentation. Duration T SHOW The time offset value t may indicate the time length of each track displayed. OFF The time delay that lighting device 580 should apply to the start of a presentation relative to receiving a command to perform the presentation may be indicated. For example, via a time offset value t OFF , lighting device 580 may be configured to start a presentation at a different time than one or more other lighting devices that are also configured to present in response to a command (e.g., the same command). For example, the intensity trajectory for a corresponding presentation may define an intensity level L over time. CP (t), where L CP (t) = L SHOW (t + t OFF ). The frequency adjustment value may indicate whether the lighting device is to repeat the display and / or how fast the lighting device is to repeat the display. In some examples, the frequency adjustment value may be a frequency adjustment scalar α FREQ , so that the intensity trajectory of the corresponding display can define the intensity level L over time CP (t), where L CP (t) = L SHOW ([α FREQ · f INIT ] · t), and f INIT is the initial frequency of the display.

[0138] The intensity adjustment value may indicate that the lighting device 580 controls the duration T of the display. SHOW The intensity level L of the intensity trajectory over time to be applied when the intensity level of light emitted from one or more emitters is L CPFor example, the presentation information may indicate a default trajectory, and lighting device 580 may be configured to generate an intensity trajectory for the corresponding presentation based on the intensity adjustment value, e.g., so that the intensity level of lighting device 580 is different from the intensity level of light emitted by one or more other lighting devices that are also configured to perform the presentation. For example, the intensity adjustment value may be an intensity adjustment offset L OFF , which can be added to the intensity level L over time indicated by the default display SHOW (t) to generate the intensity level L over time corresponding to the intensity trajectory shown CP (t), for example, L CP (t) = L SHOW (t)+ L OFF For example, the intensity adjustment value may be the intensity adjustment scalar L SC , which can be multiplied by the intensity level L over time indicated by the default display SHOW (t) to generate the intensity level L over time corresponding to the intensity trajectory shown CP (t), for example, L CP (t) = L SC · L SHOW (t).

[0139] At 556, lighting device 580 may receive a command to perform a show from computing device 570 (e.g., or other device within the system). For example, lighting device 580 may receive the command directly or indirectly from computing device 570 and / or receive the command from another device (such as a dimmer switch and / or a remote control device). In some cases, lighting device 580 may receive the show information, auxiliary information, and / or commands via a wireless communication channel. In some examples, at 556, lighting device 580 may control a driver circuit for controlling the intensity level and color of light emitted from one or more emitters to generate a show, wherein the intensity level and color of light emitted from the one or more emitters is a function of the show information and auxiliary information stored in memory at 554. In this way, lighting device 580 may control the driver circuit in response to the command and based on the show information and auxiliary information stored in memory for controlling, for example, based on receiving a command to perform a show (e.g., a single command) for a duration T defined by the auxiliary information. SHOW Thus, using process 550, lighting device 580 can perform a display without having to stream discrete instructions (e.g., such as required by process 500) from one or more external computing devices.

[0140] At 558, lighting device 580 may retrieve presentation information and / or auxiliary information from a memory (e.g., non-volatile and / or long-term memory) of lighting device 580. At 560a, lighting device 580 may be configured to control one or more emitters to display the presentation information and / or auxiliary information at time t 1 The target intensity level and / or target color are emitted as defined by the display information and / or the auxiliary information. 1 Start a presentation (eg, start a corresponding presentation of lighting device 580).

[0141] The start time of the show is related to the time when the command to perform the show is received at the lighting device 580. As such, the start time of the show can be related to the time when the command to perform the show is received by the lighting device 580. Furthermore, in some examples, the lighting device 580 can be configured to be coupled to an alternating current (AC) power source for receiving an AC mains voltage. In such examples, the control circuit can be configured to perform the show in response to receiving the command to perform the show and based on one or more zero crossings of the AC mains voltage. For example, the zero crossings of the AC mains voltage can be used as a common timing mechanism so that multiple different lighting devices can coordinate the start of a show.

[0142] At 560b, lighting device 580 may be configured to control one or more emitters to emit light at time t 2 The target intensity level and / or target color are defined by the display information and / or auxiliary information stored in the memory. The lighting device 580 may continue to control (e.g., periodically control) the target intensity level and / or target color defined by the display information and / or auxiliary information stored in the memory from time t 2 Until 560n (e.g., at the end of the presentation, at time t n ) emitted. Thus, the lighting device 580 may be configured to control the driving circuit based on receiving a (eg, single) command to perform a display to control the display for a duration T based on the display information and auxiliary information stored in the memory of the lighting device. SHOW In other words, the lighting device 580 can be configured to control the driving circuit of the lighting device 580 to control the intensity level and color of the light emitted from the emitter with respect to time during the display. SHOW The intensity level and color of the accumulated light emitted from one or more emitters of lighting device 580 at multiple different times during the period.

[0143] As described above, process 550 may be configured to be performed by each of the plurality of lighting devices. In such an example, the plurality of lighting devices may be configured to coordinate the start of a presentation based on receipt of a single command (e.g., a command sent by computing device 570 at 556). In addition, each of the plurality of lighting devices 580 may be configured with presentation information (e.g., a default presentation) and auxiliary information. The auxiliary information may be specific to each respective lighting device (e.g., unique to each respective lighting device). In this way, each of the plurality of lighting devices may be configured to emit light having slightly different characteristics (e.g., intensity, color, etc.) such that the combination of emitted light from all lighting devices generates a coordinated presentation.

[0144] For example, each lighting device may be configured to apply the auxiliary information to the show information to generate a corresponding show. The show information may define a default show, and the auxiliary information may define some changes to the default show. In this way, the corresponding show may be defined as a combination of the show information (e.g., common to all lighting devices) and the auxiliary information (e.g., which may be specific to each lighting device). In response to receiving a command to perform a show, each lighting device may drive one or more emitters to perform a corresponding show for a duration T based on the show information and the auxiliary information (e.g., the respective corresponding show stored in a memory in each lighting device). SHOW A plurality of lighting devices may generate a display when all of the lighting devices emit light according to their respective corresponding displays at the same time.

[0145] Finally, although described primarily with reference to various characteristics of emitted light, process 550 may be performed by a device that controls characteristics of other load types, such as the types of loads described herein (e.g., speakers, motorized window treatments, etc.). Such non-lighting control devices may be configured to receive the presentation information and the auxiliary information. However, in such examples, the presentation information may define how the characteristics of the load type of the control device (e.g., the frequency and / or volume of the sound emitted by the speaker, the position of the motorized window treatment, etc.) are displayed over time (e.g., over the duration T of the presentation). SHOW Similarly, the auxiliary information may define a device-specific adjustment to one or more of the characteristics (e.g., an adjustment to frequency and / or volume). The non-lighting control device may be configured to store the display information and / or the auxiliary information in a memory prior to receiving a command to perform a display. Thus, some systems may include a lighting control device and a non-lighting control device, and a computing device (e.g., a system controller) may be configured to coordinate multiple loads of various types for a display, such as the emission of light, the generation of sound, the movement of one or more objects (e.g., electric window treatments in a space), etc., based on, for example, receiving a command (e.g., a single command).

[0146] Fig. 6A 600 is a flow chart of an example process 600 for generating a display using a lighting device of a lighting system. Process 600 may be performed by a lighting device such as Figure 1A The lighting device 100 shown, Figure 1B lighting fixtures 110a to 110d, Figure 3 The lighting device 300 shown and / or the lighting device 580 of FIG. 5 . Process 600 may be performed by a control circuit of the lighting device (e.g., lighting device control circuit 340). The control circuit may perform process 600 periodically and / or in response to receiving presentation information and / or auxiliary information.

[0147] The control circuit may perform process 600 to cause one or more emitters of a lighting device to emit light according to a display. As described herein, in some cases, a display may be a combination of light emitted from a plurality of lighting devices, wherein each lighting device emits light according to a respective corresponding display, and the combination of all corresponding displays generates a display. Thus, using process 600, the control circuit may be configured to receive and store display information and / or auxiliary information, which may be used, for example, to enable a plurality of lighting devices to perform a coordinated display. The display information may define predefined lighting content, which is stored in a memory of the lighting device prior to receiving the command to perform the display. For example, the predefined lighting content may include illumination instructions that cause a plurality of lighting devices to emit light that simulates a cyclic rainbow, simulates the flickering of a candle, simulates sunlight shining through a forest canopy, simulates a breathing pattern (e.g., yoga / meditation / exercise), or simulates a weather event (e.g., cloud movement, lightning, northern lights, night sky, etc.). The auxiliary information may be specific to each lighting device (e.g., unique to each lighting device). The lighting device may be configured to generate a corresponding display using the display information and the auxiliary information.

[0148] Process 600 may begin at 610. At 612, the control circuit may receive presentation information and auxiliary information from a computing device (such as a mobile device, such as a smartphone, a tablet computer, and / or a system controller). At 614, the control circuit may store the presentation information and auxiliary information in a memory (e.g., non-volatile and / or long-term memory) of the lighting device. The presentation information may define a duration T of the presentation. SHOW In this way, the lighting device can store thereon (e.g., in a non-volatile and / or long-term memory) a duration T of the presentation. SHOW between multiple different intensity values ​​with respect to time and / or during the duration T of the presentation SHOWThus, after receiving presentation information and / or auxiliary information, for example, the control circuitry need not stream multiple different intensity values ​​and / or color values ​​when making a presentation.

[0149] The display information may be defined by one or more tracks (e.g., default tracks). The track may define a characteristic (e.g., a single characteristic) of light emitted from one or more emitters (e.g., an intensity value and / or one or more color values, such as CCT values, XY chromaticity coordinate values, and / or RGB values, etc.) over time. For example, the display information may define a first track that defines a display intensity level L over time. SHOW (t). In addition, the presentation information may define one or more other tracks that define color over time (e.g., CCT values, XY chromaticity coordinate values, and / or RGB values). For example, the one or more other tracks that define color over time may include CCT values ​​T over time. SHOW (t). In addition, one or more other tracks defining color over time may include x chromaticity coordinate values ​​x over time SHOW (t) and the y chromaticity coordinate value Y over time SHOW (t). In addition, one or more other tracks defining the color over time may include the red value R over time. SHOW (t), green value G over time SHOW (t) and the blue value B over time SHOW (t). Therefore, the presentation information may define the duration of the presentation, T SHOW The relationship between one or more characteristics of light emitted from the image (e.g., intensity value, CCT value, XY chromaticity coordinate value, RGB value, etc.) and time.

[0150] In some examples, the trajectory defined by the presentation information may be generated using one or more functions. One example of a function that may be used to generate a trajectory is a spline function, such as a basic spline function (e.g., a B-spline function). Each function (e.g., a spline) may define a time duration T of the presentation. SHOW The relationship between the characteristics of light emitted in the display information and time. For example, the display information may include multiple splines, and the lighting device may be configured to generate a default display based on one or more splines. For example, when the segments of the function are connected, the spline function may be a piecewise polynomial function defined by a number of breakpoints (e.g., nodes). For example, the display information may include multiple breakpoints of the spline function for each trajectory defined by the display information, and the lighting device may be configured to generate a default trajectory (e.g., L based on the breakpoints and using the spline function. SHOW (t), T SHOW (t), [X SHOW (t),Y SHOW(t)]、[R SHOW (t), G SHOW (t), B SHOW (t)], etc.). For example, when a presentation includes multiple lighting devices, the presentation information sent to each of the lighting devices may be the same, so that the lighting devices can generate the same default trajectory for the presentation.

[0151] The auxiliary information may be specific to a lighting device. For example, different auxiliary information may be provided to at least one other lighting device that is also configured to generate a presentation (eg, emit light according to the presentation information). The auxiliary information may include a duration T SHOW , time offset value t OFF , frequency adjustment value and / or intensity adjustment value associated with the presentation. Duration T SHOW The time offset value t may indicate the time length of each track displayed. OFF The time delay that the lighting device should apply to the start of the show relative to receiving the command to perform the show can be indicated. For example, via the time offset value t OFF , a lighting device may be configured to start a presentation at a different time than one or more other lighting devices that are also configured to present in response to a command (e.g., the same command). For example, the intensity trajectory for a corresponding presentation may define an intensity level L over time. CP (t), where L CP (t) = L SHOW (t+ t OFF ). The frequency adjustment value may indicate whether the lighting device is to be repeatedly displayed and / or may indicate an adjustment to the frequency of the repeated display of the lighting device. In some examples, the frequency adjustment value may be a frequency adjustment scalar α FREQ , so that the intensity trajectory of the corresponding display can define the intensity level L over time CP (t), where L CP (t) = L SHOW ([α FREQ · f INIT ] · t), and f INIT is the initial frequency of the display.

[0152] The intensity adjustment value may indicate the duration T of the lighting device during control. SHOW The intensity level L of the intensity trajectory over time to be applied when the intensity level of light emitted from one or more emitters is L CPFor example, the presentation information may indicate a default trajectory, and the lighting device may be configured to generate an intensity trajectory for the corresponding presentation based on the intensity adjustment value, for example, so that the intensity level of the lighting device is different from the intensity level of light emitted by one or more other lighting devices that are also configured to perform the presentation. For example, the intensity adjustment value may be an intensity adjustment offset L OFF , which can be added to the intensity level L over time indicated by the default display SHOW (t) to generate the intensity level L over time corresponding to the intensity trajectory shown CP (t), for example, L CP (t) = L SHOW (t) + L OFF For example, the intensity adjustment value may be the intensity adjustment scalar L SC , which can be multiplied by the intensity level L over time indicated by the default display SHOW (t) to generate the intensity level L over time corresponding to the intensity trajectory shown CP (t), for example, L CP (t) = L SC ·L SHOW (t).

[0153] At 616, the control circuitry may receive a command to perform the display. The command may be received from a computing device, such as a mobile device, a dimmer switch, and / or a system controller. For example, the control circuitry may receive the command directly or indirectly from the computing device and / or another device, such as a dimmer switch, may receive the command. In some cases, the control circuitry may receive the display information, the auxiliary information, and / or the command via a wireless communication channel. In response to receiving the command at 616, the control circuitry may retrieve the display information and / or the auxiliary information from a memory (e.g., non-volatile and / or long-term memory) of the lighting device.

[0154] At 618, the control circuitry may control the driver circuitry of the lighting device to control the intensity level and color of the light emitted from the one or more emitters to generate the show. As such, the intensity level and color of the light emitted from the one or more emitters may be a function of the show information and the auxiliary information stored in the memory at 614. Thus, in response to the command and based on the show information and the auxiliary information stored in the memory, the control circuitry may control the driver circuitry to control the light emitted from the one or more emitters for a duration T defined by the auxiliary information. SHOW The control circuitry may be configured to control the one or more emitters to emit light over a duration T of the presentation, for example, based on receiving a command (e.g., a single command) to perform the presentation. SHOWThe display emits light at an intensity level and / or color as defined by the display information and the auxiliary information. Thus, using process 600, the control circuitry may perform a display without having to receive a discrete instruction stream (e.g., such as required by process 500) from one or more external computing devices.

[0155] The control circuit can be configured to start the show based on receiving (e.g., at 616) a command to perform the show (e.g., the reception time). Thus, the start time of the show can be related to the time when the control circuit receives the command to perform the show. In addition, in some examples, the lighting device 580 can be configured to be coupled to an AC power source for receiving an AC mains voltage. In such an example, the control circuit can be configured to perform the show in response to receiving the command to perform the show and based on one or more zero crossings of the AC mains voltage. For example, the zero crossings of the AC mains voltage can be used as a common timing mechanism so that multiple different lighting devices can coordinate the start of the show.

[0156] As described above, process 600 may be configured to be performed by multiple lighting devices. In such an example, the multiple lighting devices may be configured to coordinate the start of a presentation based on receiving a single command. In addition, each of the multiple lighting devices may be configured with presentation information (e.g., a default presentation) and auxiliary information. The auxiliary information may be specific to each respective lighting device in the presentation (e.g., unique to each respective lighting device). In this way, each of the multiple lighting devices may be configured to emit light with slightly different characteristics (e.g., intensity level, color, etc.) so that the combination of emitted light from all lighting devices generates a coordinated presentation.

[0157] For example, each lighting device may be configured to apply the auxiliary information to the show information to generate a corresponding show. The show information may define a default show, and the auxiliary information may define some changes to the default show. In this way, the corresponding show may be defined as a combination of the show information (e.g., common to all lighting devices) and the auxiliary information (e.g., which may be specific to each lighting device). In response to receiving a command to perform a show, each lighting device may drive one or more emitters to perform a corresponding show for a duration T based on the show information and the auxiliary information (e.g., the respective corresponding show stored in a memory in each lighting device). SHOW A plurality of lighting devices may generate a display when all of the lighting devices emit light according to their respective corresponding displays at the same time.

[0158] In some examples, a user may be configured to adjust the characteristics of the light emitted during a presentation (e.g., increase or decrease the intensity level, adjust the color, etc.). For example, the control circuit may be configured to adjust the characteristics of the light emitted during a presentation while the control circuit is performing a presentation (e.g., for a duration T defined by the auxiliary information). SHOWThe control circuit may be configured to control the drive circuit to adjust the intensity of the display during the duration T of the display based on the adjustment command (e.g., and further based on the display information and auxiliary information stored in the memory). SHOW The control circuitry may be configured to adjust a characteristic of light emitted from one or more emitters during a display operation. The adjustment command may include a command to adjust a characteristic of the emitted light (such as an intensity level or color of the emitted light), which is to be executed in conjunction with the display information and / or the auxiliary information. That is, the adjustment command may be used to adjust the intensity level and / or color of the display information and the auxiliary information. For example, the control circuitry may be configured to determine an adjustment amount for the intensity level (e.g., an intensity adjustment value, which in some examples may be used as a base intensity level for the display) in response to actuation of a raise / lower actuator (e.g., an intensity adjustment actuator) of a dimmer switch.

[0159] Finally, although described primarily with reference to various characteristics of emitted light, process 600 may be performed by a device that controls characteristics of other load types, such as the types of loads described herein (e.g., speakers, motorized window treatments, etc.). Such non-lighting control devices may be configured to receive the display information and the auxiliary information. However, in such examples, the display information may define the characteristics of the load type of the control device (e.g., the frequency and / or volume of the sound emitted by the speaker, the position of the motorized window treatment, etc.) over time (e.g., the duration of the display T). SHOW ). Similarly, the auxiliary information may define a device-specific adjustment to one or more of the characteristics (e.g., an adjustment to frequency and / or volume). The non-lighting control device may be configured to store the display information and / or the auxiliary information in a memory prior to receiving a command to perform a display. Thus, some systems may include a lighting control device and a non-lighting control device, and a computing device (e.g., a system controller) may be configured to coordinate multiple loads of various types for a display, such as the emission of light, the generation of sound, the movement of one or more objects (e.g., motorized window treatments in a space), etc., based on, for example, receiving a command (e.g., a single command).

[0160] Figure 6B 6 is a flow chart of an example process 650 for generating and storing corresponding presentations using a lighting device of a lighting control system. The process 650 may be performed by a lighting device such as Figure 1A The lighting device 100, Figure 1B lighting fixtures 110a to 110d, Figure 3Process 650 may be performed by a control circuit of a lighting device (e.g., lighting device control circuit 340). The control circuit may perform process 650 in response to receiving presentation information and / or auxiliary information and / or in response to receiving an instruction to perform a presentation. For example, after receiving presentation information and auxiliary information, the control circuit may perform process 650.

[0161] The control circuitry may perform process 650 to generate a corresponding display (e.g., one or more corresponding tracks). As described herein, a corresponding display may be defined by a combination of display information and auxiliary information received by the lighting device. For example, the lighting device may be configured to generate corresponding corresponding displays, wherein the combination of all corresponding displays may constitute a display.

[0162] Process 650 may begin at 660. At 662, the control circuit may retrieve display information and / or auxiliary information from a memory of the lighting device. At 664, the control circuit may use the display information to generate a default display. As described herein, multiple lighting devices may receive the same display information, and therefore, the display information may define a default display. In addition, in some examples, the display message may be defined by one or more trajectories (e.g., default trajectories). The trajectory may define a characteristic (e.g., a single characteristic) of light emitted from one or more emitters (e.g., an intensity value and / or one or more color values, such as CCT values, XY chromaticity coordinate values, and / or RGB values, etc.) over time. In some examples, the trajectory defined by the display information may be generated using one or more functions. An example of a function that can be used to generate a trajectory is a spline function, such as a basic spline function (e.g., a B-spline function). Each function (e.g., a spline) may define a time duration T of the display. SHOW For example, the display information may include a plurality of splines, and the lighting device may be configured to generate a default display based on one or more splines.

[0163] At 666, the control circuitry can determine whether the lighting device has received and / or stored auxiliary information (e.g., related to the presentation information). For example, as described herein, the auxiliary information can define one or more characteristics specific to each lighting device (e.g., unique to each lighting device). For example, the auxiliary information can include a duration T SHOW , time offset value t OFF , frequency adjustment value and / or intensity adjustment value associated with the presentation information.

[0164] If the control circuit determines at 666 that the auxiliary information exists, the control circuit may generate a corresponding presentation based on the auxiliary information according to the default presentation at 670. That is, the control circuit may generate a corresponding presentation specific to the lighting device based on the presentation information (e.g., or the default trajectory) and the auxiliary information. As mentioned herein, the auxiliary information may include a duration T SHOW , color shift value t OFF , a frequency adjustment value, an intensity adjustment value associated with the presentation, and / or a color shift associated with the presentation. For example, a corresponding presentation may define an intensity level L over time. CP (t), where L CP (t) = L SHOW (t + t OFF ). The frequency adjustment value can be the frequency adjustment scalar α FREQ , so that the intensity trajectory of the corresponding display can define the intensity level L over time CP (t), where L CP (t) = L SHOW ([α FREQ · f INIT ] · t), and f INIT is the initial frequency of the display. The color shift may indicate the change of the color defined by the display information. The intensity adjustment value may indicate the intensity of the lighting device when controlling the duration T of the display. SHOW The intensity level L of the intensity trajectory over time to be applied when the intensity level of light emitted from one or more emitters is L CP At 672 , the control circuitry may store the corresponding presentation along with the presentation name in a memory and may exit process 650 .

[0165] However, if the control circuit determines at 666 that the auxiliary information is not present, the control circuit may set the corresponding presentation to be the same as the default presentation (e.g., with respect to the animated image) based on the auxiliary information at 668. At 672, the control circuit may store the corresponding presentation in memory along with the presentation name, and process 650 may exit. Thus, using process 650, the control circuit may be configured to generate a corresponding presentation to be used during a presentation based on the presentation information and associated auxiliary information (if received).

[0166] Figure 7 is a flow chart of an example process 700 for responding to a raise or lower command using a lighting fixture of a lighting control system. The process 700 may be performed by a lighting fixture such as Figure 1A The lighting device 100, Figure 1B lighting fixtures 110a to 110d, Figure 3Process 700 may be performed by a lighting device 300 shown in FIG. 5 and / or lighting device 580 of FIG. 5 . Process 700 may be performed by a control circuit of a lighting device (e.g., lighting device control circuit 340). The control circuit may perform process 700 in response to receiving an adjustment command (e.g., via a toggle actuator of the lighting device).

[0167] The control circuit may perform process 700 to adjust a characteristic of the emitted light (e.g., to increase or decrease the intensity level), such as when a presentation is being made or when a presentation is not being made. As described herein, in some cases, a presentation may be a combination of light emitted from a plurality of lighting devices, wherein each lighting device emits light according to a respective corresponding presentation, and the combination of all corresponding presentations generates the presentation. The presentation information may indicate predefined lighting content that is stored in a memory of the lighting device prior to receiving a command to make a presentation. The auxiliary information may be specific to each lighting device (e.g., unique to each lighting device). The lighting device may be configured to use the presentation information and the auxiliary information to generate a corresponding presentation. Using process 700, the control circuit may be configured to adjust a characteristic of the emitted light (e.g., to increase or decrease the intensity level), such as when a presentation is being made or when a presentation is not being made.

[0168] Process 700 may start at 710. At 712, the control circuit may receive an adjustment command, such as an intensity increase command or an intensity decrease command. For example, the user may be configured to adjust the characteristics of the emitted light using an actuator of the lighting device and / or via a graphical user interface (GUI) (e.g., a computing device and / or an external device). Although process 700 is described in the context of an intensity increase or intensity decrease command, as described herein, the adjustment command may be a command to adjust the characteristics of the emitted light, such as an increase intensity command, a decrease intensity command, an adjust color command, an adjust start time command, or an adjust frequency command. The adjustment command may include a command to adjust the characteristics of the emitted light (such as the intensity level or color of the emitted light), which is to be executed together with the display information and / or the auxiliary information. That is, the adjustment command may be used to adjust the intensity level and / or color of the display information and the auxiliary information. For example, the control circuit may be configured to determine the adjustment amount of the intensity level (e.g., an increase intensity command or a decrease intensity command) in response to actuation of an increase actuator or a decrease actuator (e.g., an intensity adjustment actuator) of a dimmer switch or remote control, respectively.

[0169] At 714, the control circuitry may determine whether the lighting device is performing a show. For example, the control circuitry may determine whether an increase or decrease command is received while the lighting device is performing a show. While performing a show, the lighting device may control one or more characteristics of the emitted light based on the show information and / or the auxiliary information. If, at 714, the control circuitry determines that the lighting device is performing a show, then at 716, the control circuitry may determine whether the adjustment command is an increase intensity command or a decrease intensity command. Additionally, as described herein, while performing a show, the control circuitry may set a target intensity level based on the corresponding show and the current time (e.g., before the adjustment is made at 718 or 720).

[0170] If at 716 the control circuit determines that the adjustment command is an increase intensity command, then at 718 the control circuit may cause the intensity adjustment scalar L SC The amount indicated by the increase intensity command is increased, and the control circuit may then exit process 700. In some examples, the increase intensity command may indicate an intensity adjustment of a fixed amount. In other examples, the increase intensity command may indicate an intensity adjustment scalar L SC , which can be multiplied by the intensity level L over time corresponding to the intensity trajectory displayed CP (t), for example, L CP (t) = L SC · L CP (t). Alternatively, the increase intensity command may indicate an intensity adjustment offset L OFF , the intensity adjustment offset may be added to the intensity level L over time of the intensity trajectory corresponding to the display CP (t), for example, L CP (t) = L CP (t) + L OFF .

[0171] If at 716 the control circuit determines that the adjustment command is a decrease intensity command, then at 720 the control circuit may cause the intensity adjustment scalar L SC The amount indicated by the reduce intensity command is reduced, and the control circuit may then exit process 700. In some examples, the reduce intensity command may indicate an intensity adjustment of a fixed amount. In other examples, the reduce intensity command may indicate an intensity adjustment scalar L SC , which can be multiplied by the intensity level L over time corresponding to the intensity trajectory displayed CP (t), for example, L CP (t) = L SC · L CP Alternatively, the intensity reduction command may indicate an intensity adjustment offset L OFF , which can be seen from the intensity level L over time CP (t) Subtract the intensity adjustment offset, e.g., LCP (t) = L CP (t) + L OFF .

[0172] If at 714 the control circuitry determines that the lighting device is not on display, then at 722 the control circuitry may determine whether the adjustment command is an increase intensity command or a decrease intensity command. For example, if not on display, the control circuitry may set the target intensity level to a static intensity level (e.g., an intensity level that does not change over time). If at 722 the control circuitry determines that the adjustment command is an increase intensity command, then at 724 the control circuitry may set the target intensity level L of the lighting load to a static intensity level (e.g., an intensity level that does not change over time). TRGT The increase is increased by the amount indicated by the increase intensity command, and the control circuit may then exit process 700. If, at 722, the control circuit determines that the adjustment command is a decrease intensity command, then at 720, the control circuit may lower the target intensity level L of the lighting load. TRGT The amount indicated by the reduce intensity command is reduced, and the control circuitry may then exit process 700 .

[0173] Fig. 8A 8 is a flow chart of an example process 800 for assigning a location to one or more lighting devices of a lighting control system. The process 800 may be performed by a device such as Figure 1A The computing device 160 shown, Figure 1B The computing device 150b, the remote control device of the lighting control system 100, the system controller of the lighting control system 100, Figure 1B The system controller 140b and / or Figure 4 The process 800 may be performed by a control circuit of the device (e.g., control circuit 431). The control circuit may perform the process 800 during initial configuration of a display. The control circuit may perform the process 800 to assign locations to lighting devices using a floor plan. Once the locations of the lighting devices are assigned, the control circuit may determine auxiliary information for each lighting device so that the plurality of lighting devices are configured to generate a coordinated display.

[0174] The control circuit may begin process 800 at 810. At 812, the control circuit may retrieve a floor plan of the space. In some examples, the floor plan may include one or more icons that define the locations of lighting devices and / or load control devices (e.g., LED drivers) on the floor plan, which icons may be created during a design phase prior to installation and commissioning. In some examples, the control circuit may be configured to generate a graphical user interface that displays the floor plan with icons, and the control circuit may be configured to receive user input via the graphical user interface, thereby allowing configuration and / or control of the type and / or location of the lighting devices and / or load control devices associated with the icons. An example of a configuration process for a load control system is described in more detail in U.S. Patent No. 11,687,223, entitled CONFIGURING A LOAD CONTROL SYSTEM, issued on June 27, 2023, the entire disclosure of which is hereby incorporated by reference.

[0175] At 814, the control circuitry may define an origin on the floor plan. For example, a user may use a graphical user interface to select a point on the floor plan to set as the origin, or the control circuitry may default to the origin. Alternatively, the control circuitry (e.g., instructions resident on a memory of the control circuitry) may automatically select a location for the origin on the floor plan (e.g., in the center of the floor plan or in the lower left corner of the floor plan). At 816, the control circuitry may select a device on the floor plan, such as a lighting device (e.g., based on an icon defining a location for the lighting device). The floor plan may include multiple devices with predefined locations and / or a technician may add a device to the floor plan based on the actual location of the device within the space.

[0176] At 818, the control circuit may determine or assign location information for the selected device. For example, the control circuit may determine the location information using a graphical user interface and / or based on user input. The location information may include coordinates, such as X coordinates, XY coordinates, or XYZ coordinates (e.g., one-dimensional coordinates, two-dimensional coordinates, or three-dimensional coordinates). For some lighting devices and / or lighting fixtures, such as downlights, lamps, and other point light sources, the control circuit may use the location information of the icons of the lighting devices and / or load control devices on the plan view. However, for some types of lighting devices, such as linear lighting devices, the lighting devices may not have easily defined locations. For example, linear lighting devices may extend a long distance and may not be easily assigned to a single location. In such an example, the control circuit may determine the location information based on any combination of the following. The control circuit may determine the location information of the linear lighting device based on the location of the load control device (e.g., LED driver) that controls the linear lighting device as a single area (e.g., the coordinates may be determined as one end or the other end of the linear lighting device). The control circuit may determine the location information of the linear lighting device based on the midpoint of the lighting device. The control circuitry may determine the position information of the linear lighting device as either end of the fixture (e.g., independent of the location of the load control device). In some examples, individual segments of the linear lighting device may be individually addressable, and in such cases, the control circuitry may determine the position information of each individually addressable segment of the linear lighting device.

[0177] At 820, the control circuitry may store the location information of the device in a memory of the device (e.g., memory 432) (e.g., as system configuration data). At 822, the control circuitry may determine whether there are more lighting devices within the lighting control system to which location information is to be assigned. If there are additional lighting devices, at 824, the control circuitry may select the next device and may proceed back to 818. If there are no additional lighting devices, the control circuitry may exit process 800.

[0178] Figure 8B 8 is a flow chart of an example process 850 for assigning a sequential number to one or more lighting devices of a lighting control system. The process 850 may be performed by a device such as Figure 1A The computing device 160, Figure 1B The computing device 150b, the remote control device of the lighting control system 100, the system controller of the lighting control system 100, Figure 1B The system controller 140b and / or Figure 4 Process 850 may be performed by a control circuit of the device (e.g., control circuit 431). The control circuit may perform process 850 during an initial configuration of the display. The control circuit may perform process 850 to assign sequential numbers N to the lighting devices using the plan view. ORDEROnce the lighting device sequence number N ORDER Once assigned, the control circuit can determine the auxiliary information for each lighting device so that the multiple lighting devices are configured to generate a collaborative display.

[0179] At 851, the control circuitry may begin process 850. At 852, the control circuitry may select a device (e.g., a lighting device) from a plurality of devices within the space. For example, the control circuitry may select the device based on a user selection received via a user interface (e.g., a user may select the device by selecting an icon on a floor plan). Alternatively, the control circuitry may select the device in the space via a smartphone using a Bluetooth Low Energy (BLE) beacon.

[0180] At 854, the control circuit may assign a sequence number N to the device. ORDER For example, the control circuit may select the sequence number N based on user input. ORDER (For example, a user may manually assign sequence numbers by selecting a sequence number from among many possible sequence numbers.) The control circuitry may sequentially assign sequence numbers N to each device. ORDER to (e.g., automatically) select a sequence number N for the device itself ORDER (For example, the first selected device is assigned a sequence number N ORDER 1. The second selected device is assigned a sequence number N ORDER 2, etc.). The control circuit can assign a unique sequential number N to the device ORDER Alternatively or in addition, the control circuit may assign the same sequence number N to multiple devices (eg, two devices). ORDER (For example, if the devices are within a threshold distance of each other, such as within 6 inches of each other.) In addition, in some cases, the control circuitry may skip sequence number N. ORDER , such as when the distance between the devices may be larger (eg, when the distance between the devices exceeds a threshold distance).

[0181] At 856, the control circuit may store the sequence number N of the selected device. ORDER In addition, in some examples, the control circuit may number the sequence N ORDER At 858, the control circuitry may determine whether there are more devices within the lighting control system to be assigned sequence numbers N. ORDER If there are additional devices, then at 860 , the control circuitry may select the next device and may proceed back to 854 .

[0182] If there are no additional devices, then at 862, the control circuit may determine the time offset t of the plurality of devices in the space. OFF For example, the control circuit may be based on the sequential number N of the device ORDER, the highest sequence number N assigned to any of the multiple devices in the space ORDER and / or the duration of the display T SHOW To determine the time offset t of the device OFF In some examples, the control circuit may determine a time offset t for a subset of the plurality of devices within the space. OFF (For example, not all devices must be assigned a time offset t OFF ). Time offset value t OFF A time delay within a presentation may be indicated, where the device is configured to start the presentation upon receiving a command to do so. For example, via a time offset value t OFF , a device may be configured to start a presentation at a different time than one or more other devices that are also configured to present in response to a command (e.g., the same command). For example, the intensity trajectory for a corresponding presentation may define an intensity level L over time. CP (t), where L CP (t) = L SHOW (t + t OFF ). In addition, as described herein, the control circuit may depend on the specific sequence number N of each device. ORDER To calculate the time offset t OFF (For example, as a time offset t as part of the assistance information assigned to each device OFF ). For example, the control circuit may be based on the specific sequence number N of the device ORDER , the highest sequence number N among the assigned sequence numbers HI and the duration of the display, T SHOW To calculate the time offset t OFF , for example, t OFF = (T SHOW / N HI ) · N ORDER Additionally, at 862, the control circuitry may store a time offset t associated with each of the plurality of devices prior to exiting process 850. OFF .

[0183] In some examples, the presentation may be generated based on an animated image (e.g., an animated Graphics Interchange Format (GIF) image). An animated image may be a number of images (e.g., frames) that change over time. For example, a user may select an animated image, and a device (e.g., a control device) may generate presentation information and auxiliary information based on the number of devices, the positioning (e.g., location) of the devices, and / or the type of devices configured to generate the presentation. As described herein, in some cases, each lighting device may be assigned a location (e.g., within a space or room) and / or a position (e.g., within a sequence of devices). Then, based on the positioning and / or position of each lighting device, each lighting device may be assigned auxiliary information. In some examples, the presentation and auxiliary information may be based on the animated image selected by the user.

[0184] Fig.9A 9 is a flow chart of an example process 900 for distributing presentation information and auxiliary information of an animated image to one or more lighting devices of a lighting control system. The process 900 may be performed by a device such as Figure 1A The computing device 160 shown, Figure 1B The computing device 150b, the remote control device of the lighting control system 100, the system controller of the lighting control system 100, Figure 1B The system controller 140b and / or Figure 4 Process 900 may be performed by a control circuit of a device (e.g., control circuit 431). The control circuit may perform process 900 before assigning presentation information and / or auxiliary information to one or more lighting devices within a space. The control circuit may perform process 900 after assigning locations to lighting devices, for example, using a floor plan (e.g., as described with respect to process 800).

[0185] The control circuitry may begin process 900 at 910. At 912, the control circuitry may determine location information of one or more devices (e.g., one or more lighting devices to be displayed). For example, the control device may determine location information of one or more devices using process 900. As described herein, the location information may be one-dimensional location information, two-dimensional location information, or three-dimensional location information associated with the physical location of the device in space.

[0186] At 914, the control circuit may retrieve (e.g., from a memory) data of an animated image. An animated image may be associated with a plurality of pixels, and the plurality of pixels may be defined by changing intensity levels and / or colors over time. An example of an animated image is a GIF image. In some examples, the control circuit may receive an animated image from a user (e.g., via a computing device, such as a system controller or a mobile device). The data of the animated image may include the number of pixels of the animated image, the duration of the animated image, and display information associated with each pixel of the animated image (e.g., the start time of the pixels of the animated image, and / or one or more characteristics of each pixel of the animated image in the duration, such as the intensity level of the pixel in the duration of the animated image, the color of the pixel in the duration of the animated image, etc.). In this way, the pixels of the animated image may have unique and / or different display information. In some examples, the control circuit may receive an animated image and generate display information for each pixel of the animated image.

[0187] At 916, the control circuitry may select a device in the display. For example, the control circuitry may select a device based on the order of the devices, based on the location of the devices in the space, and / or based on a user selection. In some examples, the control circuitry may assign a different sequence number N to each device in the system. ORDER , and the control circuit may be based on the sequence number N associated with the device ORDER At 918, the control circuitry may retrieve (eg, from memory) the location information of the selected device (eg, determined at 912).

[0188] At 920, the control circuitry may determine (e.g., select) pixels of the animated image based on the location of the selected device. Each frame of the animated image may include a plurality of pixels, and the control circuitry may determine a pixel from the plurality of pixels based on the location of the selected device and the location of the pixel within the frame. In some examples, the control circuitry may associate the pixels of the animated image with a space in which the lighting device is located. In some examples, the control circuitry may associate each pixel of the animated image with a location within the space. Then, based on the location of the pixel and the location of the selected device, the control circuitry may select the pixel based on which pixel's location within the space is closest to the location of the selected device in the space.

[0189] At 922, the control circuit may store the display information of the selected pixel with the selected device. In addition, in some examples, the control circuit may send the display information of the selected pixel to the selected device for storage at the selected device (e.g., stored in a memory of the selected device). At 924, the control circuit may determine whether there are additional devices that have not yet been associated with the display information of the pixels of the animated image. If at 924, the control circuit determines that there is at least one additional device, then at 926, the control circuit may select another device and return to 918. If the control circuit determines that there are no additional devices (e.g., all devices are associated with the display information of the pixels of the animated image), the control circuit may exit process 950. Thus, using process 950, the control circuit may associate the display information of multiple pixels of the animated image with corresponding devices (e.g., lighting devices) within the space, for example, so that these lighting devices can later perform a display that imitates the animated image.

[0190] Fig. 9B 950. The presentation (such as presentation information and auxiliary information) may be based on the animated image 950. The animated image 950 may be illustrated by a series of six bitmaps 952a to 952f and / or six corresponding images 960a to 960f, which are displayed over time (from time t 1 To time t 6 ) development. Animated image 950 may be defined by sixteen pixels (eg, each pixel is represented by a smaller box, such as pixel 954). A single pixel (such as pixel 954) may be displayed for a duration T of animated image 950. SHOW For example, the value of pixel 954 changes across bitmaps 952a to 952f and as the animated image changes over time (from time t 1 To time t 6 ) development, which can be illustrated by the different gray levels in the corresponding images 960a to 960f. 6 At the end, the animation image can return to time t 1 (e.g., multiple times in a row) or the presentation may end.

[0191] The computing device (e.g., a system controller) may be configured to generate and assign presentation information and / or auxiliary information based on the animated image. In some examples, the animated image may be an animated GIF image. The computing device may be configured to assign a location within the space to each lighting device (e.g., using the methods described herein). For example, the computing device may assign a different sequential number N to each lighting device. ORDER In such an example, the computing device may depend on the specific sequence number N of each lighting device. ORDER To calculate the time offset t OFF(For example, as a time offset t as part of the auxiliary information assigned to each lighting device OFF ). For example, the computing device may number the lighting devices N based on a specific sequence. ORDER , the highest sequence number N among the assigned sequence numbers HI and the duration of the display, T SHOW To calculate the time offset t OFF , for example, t OFF = (T SHOW / N HI ) ·N ORDER In addition, in some examples, the computing device may be configured to use input received from a mobile device (e.g., augmented reality software) to generate a two-dimensional map of the lighting load within the space. The computing device may assign a location within the space, such as an XY coordinate, to each lighting device based on the two-dimensional map.

[0192] The computing device may allow a user to select an animated image that represents a display in the array over time.

The user can visualize what a display generated based on the animated image might look like in space by viewing the animated image on the display. The animated image may be associated with a plurality of pixels (e.g., such as pixel 954 of animated image 950).

[0193] In some examples, the animated image may represent a display over time across a two-dimensional array (e.g., such as animated image 950). However, although described in the context of a two-dimensional array, in other examples, the animated image may represent a display over time across a three-dimensional array (e.g., a three-dimensional volume where positions are defined by XYZ coordinates). Further, in other examples, the animated image may represent a display over time across a one-dimensional array (e.g., where positions are defined by X coordinates). In such examples, the X coordinate may represent a position along a length of space.

[0194] As described above, the computing device may associate one or more pixels of the animated image with each of a plurality of different lighting devices. Using the animated image 950 as an example, the animated image may include sixteen pixels, and the computing device may determine the pixels associated with each lighting device based on the location of the lighting device in the space (e.g., using a floor plan, as described herein). As described herein, the computing device may associate each lighting device with a location in the space (e.g., an XY coordinate). The computing device may associate each pixel of the animated image with a location in the space. Thus, the computing device may associate each pixel with one or more lighting devices. In some examples, there may be more than one pixel associated with a lighting device. For example, a lighting device may be configured to control the emitted light based on a mixture or average of the values ​​of the characteristics associated with the pixel. Alternatively, multiple lighting devices may be associated with a pixel (e.g., based on the number of lighting devices, the number of pixels of the animated image, and the location of the lighting device in the space). In some examples, the floor plan data may include the dimensions of multiple regions (e.g., the XY coordinates of the corners of the region), so that the animated image may be scaled on the region, or positioned / sized only relative to the dimensions of the region.

[0195] The computing device may control multiple lighting devices based on the animated image and the association between the lighting devices and the pixels of the animated image. For example, the computing device may generate presentation information and auxiliary information based on the animated image. The presentation information may be specific to each pixel or position in space. The computing device may send presentation information to each lighting device, and may send auxiliary information specific to the coordinates (e.g., location and position) of the lighting device to each lighting device. Then, the system controller may perform a presentation, and the lighting device may control the intensity level and / or color of the light emitted over time based on the presentation information and the auxiliary information to imitate the animated image. That is, the lighting device may control the intensity level and / or color of the light emitted over time based on its respective position in space to generate a presentation based on the animated image. In addition, although described in the context of a two-dimensional animated image, in other examples, the computing device may be configured to generate presentation information and auxiliary information based on a three-dimensional animation, and to generate and assign auxiliary information to each lighting device based on the position (e.g., three-dimensional coordinates, such as XYZ coordinates) assigned to the lighting device in the space.
