[0002] This application claims the benefit of Provisional U.S. Patent Application No. 63 / 319,192, filed on March 11, 2022, the disclosure of which is incorporated herein by reference in its entirety. Background Art

[0003] For example, a user environment such as a residence or an office building can be configured using various types of load control systems. A lighting control system can 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, and the digital message may include a load control instruction. The load control device may be able to directly control the electrical load. The input device may be able to indirectly control 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 curtains, temperature control devices (e.g., thermostats), AC plug-in load control devices, and the like. Examples of input devices may include remote control devices, occupancy sensors, daylight sensors, temperature sensors, and 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 (e.g., any combination of a system controller, a computing device, a dimmer, a lighting control device, and / or a lighting device) may create a custom correlated color temperature (CCT) dimming curve for a lighting load. The lighting control system may receive a high-end CCT value via user selection (e.g., via a display device), wherein the high-end CCT value is associated with a high-end intensity level of the lighting load. The lighting control system may receive a dimming curve from a plurality of selectable dimming curves via user selection. The lighting control system may determine a bend value and a CCT range based on the selected dimming curve. The lighting control system may determine a low-end CCT value based on the high-end CCT value and the CCT range, wherein the low-end CCT value is associated with a low-end intensity level of the lighting load. The lighting control system may determine (e.g., generate) a custom dimming curve based on the high-end CCT value, the low-end CCT value, and the bend value. In some examples, the lighting control system may send the custom dimming curve to the lighting load or a control device of the lighting load.

[0006] The bend value may define an amount of curvature in a line defining CCT values ​​between a high end CCT value and a low end CCT value across a dimming range. In some examples, the bend value may be a decimal value between 0 and 1.0. In some examples, a plurality of selectable dimming curves may include a warm dimming curve, a daylight dimming curve, and a cool dimming curve. In some examples, each dimming curve may be defined by a CCT range and a bend value.

[0007] A lighting control system (e.g., any combination of a system controller, a computing device, a dimmer, a lighting control device, and / or a lighting device) may create a custom correlated color temperature (CCT) dimming curve for a lighting load. The lighting control system may receive a high-end correlated color temperature (CCT) value via user selection, wherein the high-end CCT value is associated with a high-end intensity level of the lighting load. The lighting control system may receive a low-end CCT value via user selection, wherein the low-end CCT value is associated with a low-end intensity level of the lighting load. The lighting control system may receive an intermediate CCT value via user selection, wherein the intermediate CCT value is associated with an intermediate intensity level of the lighting load, and wherein the intermediate intensity level is between the high-end intensity level and the low-end intensity level. The lighting control system may determine a bend value based on the high-end CCT value, the low-end CCT value, and the intermediate CCT value. The lighting control system may determine (e.g., generate) a custom dimming curve based on the high-end CCT value, the low-end CCT value, and the bend value. In some examples, the lighting control system may send the custom dimming curve to the lighting load or a control device of the lighting load.

[0008] In some examples, the lighting control system can determine the bend value based on the high-end CCT value, the high-end intensity level, the low-end CCT value, the low-end intensity level, the intermediate CCT value, and the intermediate intensity level. In some examples, the lighting control system can receive the intermediate intensity level of the intermediate CCT range via user selection. In some examples, the selection of the intermediate intensity level can be constrained to a predefined intensity range.

[0009] The bend value may define the amount of curvature in a line defining CCT values ​​between a high end CCT value and a low end CCT value across the dimming range. In some examples, the bend value may be a decimal value between 0 and 1.0.

[0010] A lighting control system (e.g., a system controller, a computing device, a dimmer, a lighting control device, and / or any combination of lighting devices) may create a custom correlated color temperature (CCT) dimming curve for a lighting load. The lighting control system may receive a high-end correlated color temperature (CCT) value via a user selection (e.g., via a graphical user interface (GUI) presented on a display of a mobile device), wherein the high-end CCT value is associated with a high-end intensity level of the lighting load. The lighting control system may receive a dimming curve from a plurality of selectable dimming curves via a user selection (e.g., via a GUI presented on a display of a mobile device). The lighting control system may determine a bend value and a CCT range based on the selected dimming curve. The lighting control system may determine (e.g., calculate) a CCT value for each of a plurality of different intensity levels using the CCT range and the bend value to create a custom dimming curve. The lighting control system may send the custom dimming curve to the lighting load or a control device configured to control the lighting load.

[0011] In some examples, the lighting control system can determine (eg, calculate) a low-end CCT value based on the high-end CCT value and the CCT range, where the low-end CCT value is associated with a low-end intensity level of the lighting load.

[0012] In some examples, the lighting control system can determine the CCT value for each of a plurality of different intensity levels across a dimming range spanning from a low-end intensity level to a high-end intensity level. The dimming range can be defined by 256 dimming levels.

[0013] In some examples, the lighting control system may determine the CCT value for each of the plurality of different intensity levels across the dimming range based on an equation such as:

[0014]

[0015] Where CCT[d] is the CCT value for a specific dimming level, CCT HE It is the high-end CCT value, CCT LEis the low-end CCT value, B is the bend value, and d is the dimming level.

[0016] The bend value may define an amount of curvature in a line defining CCT values ​​between a high end CCT value and a low end CCT value across a dimming range. In some examples, the bend value may be a decimal value between 0 and 1.0. In some examples, a plurality of selectable dimming curves may include a warm dimming curve, a daylight dimming curve, and a cool dimming curve. In some examples, each dimming curve may be defined by a CCT range and a bend value.

[0017] A lighting control system (e.g., a system controller, a computing device, a dimmer, a lighting control device, and / or any combination of lighting devices) may create a custom correlated color temperature (CCT) dimming curve for a lighting load. The lighting control system may receive a high-end correlated color temperature (CCT) value via user selection, wherein the high-end CCT value is associated with a high-end intensity level of the lighting load. The lighting control system may receive a dimming curve from a plurality of selectable dimming curves via user selection. The lighting control system may determine a bend value and a CCT range based on the selected dimming curve. The lighting control system may send custom dimming curve data to the lighting load. In some examples, the custom dimming curve data may include a high-end CCT value, a CCT range, and a bend value. In some examples, the lighting control system may determine a low-end CCT value based on the high-end CCT value and the CCT range, and the custom curve data may include a low-end CCT value, a CCT range, and a bend. In some examples, the lighting control system may determine a low-end CCT value based on the high-end CCT value and the CCT range, and the custom curve data may include a high-end CCT value, a low-end CCT value, and a bend.

[0018] The bend value may define an amount of curvature in a line defining CCT values ​​between a high end CCT value and a low end CCT value across a dimming range. In some examples, the bend value may be a decimal value between 0 and 1.0. In some examples, a plurality of selectable dimming curves may include a warm dimming curve, a daylight dimming curve, and a cool dimming curve. In some examples, each dimming curve may be defined by a CCT range and a bend value.

[0019] In some examples, a lighting control system (e.g., a lighting load or a lighting control device) may receive a high-end CCT value, a CCT range, and a bend value at the lighting load, determine a low-end CCT value based on the CCT range and the high-end CCT value, and store the high-end CCT value, the low-end CCT value, and the bend value in a memory. In such examples, the lighting control system (e.g., the lighting load or the lighting control device) may control the lighting load based on a current intensity level and a current CCT value, wherein the current CCT value is determined based on the high-end CCT, the low-end CCT, and the bend value. In addition, the lighting control system (e.g., the lighting load or the lighting control device) may receive a dimming level, retrieve a high-end CCT value, a low-end CCT value, and a bend value from the memory, determine a CCT value for the dimming level based on the high-end CCT value, the low-end CCT value, and the bend value, and control the lighting load according to the dimming level and the CCT value for the dimming level. For example, the lighting control system may determine that the CCT value for each of a plurality of different intensity levels across the dimming range is performed based on an equation such as the following:

[0020]

[0021] Where CCT[d] is the CCT value for a specific dimming level, CCT HE It is the high-end CCT value, CCT LE is the low-end CCT value, B is the bend value, and d is the dimming level.

[0022] In addition, in some cases, a lighting control system (e.g., a lighting load or a lighting control device) may receive an updated high-end CCT value, calculate an updated low-end CCT value based on the updated high-end CCT value and the CCT range, and store the updated high-end CCT value and the updated low-end CCT value in a memory. The lighting control system (e.g., a lighting load or a lighting control device) may determine an updated CCT value for a dimming level based on the updated high-end CCT value, the updated low-end CCT value, and the bend value, and control the lighting load according to the dimming level and the updated CCT value for the dimming level. In some examples, the updated high-end CCT value may be determined based on the time of day. In addition, in some examples, the lighting load may be configured to operate according to a natural show control technique in which CCT values ​​across a dimming range are changed based on the time of day to simulate the CCT value of the sun throughout the day.

[0038] Figure 1 is a simplified block diagram of an example load control system (eg, a lighting control system). Figure 1 An example of a lighting control system 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 1 The smart light bulbs 120a, 120b shown in FIG. 5 may include different types of light sources (eg, incandescent lamps, fluorescent lamps, and / or light emitting diode (LED) light sources).

[0039] The smart bulbs 120a, 120b may be capable of transmitting and / or receiving wireless communications. For example, the smart bulbs 120a, 120b may each include a wireless communication circuit (e.g., a radio frequency (RF) transceiver) that is operable to transmit and / or receive wireless signals such as the RF signal 106 (e.g., using a wireless protocol such as ZIGBEE, THREAD, NFC, BLUETOOTH, BLUETOOTH LOW ENERGY (BLE), WI-FI, CLEAR CONNECT, 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 bulbs 120a, 120b may be controlled to emit light having varying intensity levels and / or colors (e.g., color temperatures, such as correlated color temperature (CCT) and / or other colors) in response to control instructions (e.g., digital messages) received in a message from another control device.

[0040] The smart bulb 120a may 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 may 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 may receive a configuration message from the dimmer 140. In response to receiving the configuration message, the smart bulb 120a may determine to control the amount of power delivered to the light source of the smart bulb according to the control message (e.g., a wireless control message) received from the dimmer 140. In some examples, the smart bulb 120a may be programmable via the RF signal 160 (e.g., to receive CCT dimming curve data), and thereafter, the smart bulb 120a may respond to the phase control AC signal from the dimmer 140, such as receiving a target intensity level L. TRGT And determine the CCT value according to the CCT dimming curve data.

[0041] 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 the 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.

[0042] 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 TRGTThe 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 CCT 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 to 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 result in the cumulative light T emitted by the lighting device being 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 CCT 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 amount of drive current that causes the CCT of the accumulated light emitted by the lighting device to be equal to the target color temperature T. TRGT Alternatively, the system may send a signal to the lighting device such that the CCT of the accumulated light emitted by the lighting device is equal to the target color temperature T TRGT The desired lumen value and / or drive current magnitude.

[0043] 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 1 Although smart light bulbs 120a and 120b are shown in FIG, any number of non-smart light bulbs and smart light bulbs may be supported in the lighting control system 100.

[0044] 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 transmit 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.

[0045] The lighting control system 100 may include one or more control devices for controlling non-intelligent bulbs and smart bulbs 120a, 120b (e.g., controlling the amount of power delivered to the light source of the bulbs). The smart bulbs 120a, 120b may be controlled substantially in unison, or individually. For example, the bulbs may be partitioned such that the smart bulb 120a may be controlled by a first control device and the smart bulb 120b may be controlled by a second control device. The control devices may be configured to turn the smart bulbs 120a, 120b on and off. For example, the control devices may 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 or CCT value) of the light emitted by the smart bulbs 120a, 120b.

[0046] The dimmer 140 may be configured as a wall mounted load control device (e.g., Figure 1). The dimmer 140 may be a smart load control device or a non-smart load control device. The dimmer 140 may be configured to be mounted to a standard electrical wall box (e.g., via a yoke) and coupled in a series electrical connection between the AC power source 102 and the smart light bulb 120a. The dimmer 140 may receive an AC mains line voltage from the AC power source 102 and may generate a phase control signal for controlling the smart light bulb 120a. The phase control signal may be a phase-cut AC waveform. An example of a wall-mounted dimmer is described in more detail in commonly assigned U.S. Patent No. 8,664,881, entitled TWO-WIRE DIMMER SWITCH FOR LOW-PO WER LOADS, issued on March 4, 2014, the entire disclosure of which is hereby incorporated by reference. Alternatively, as described above, the dimmer 140 may operate as a remote control device that is not coupled in series between the alternating current (AC) power source 102 and the smart light bulb 120a, but is otherwise mounted within the lighting control system 100 (e.g., mounted on top of an existing light switch, mounted on a wall, configured with a desktop bracket, etc.).

[0047] 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 light 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.

[0048] 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.

[0049] 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 a tablet computer). The system controller 150 may be configured to transmit 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 (e.g., using wireless protocols such as ZIGBEE, THREAD, NFC, BLUETOOTH, BLUETOOTH LOW ENERGY (BLE), WI-FI, CLEARCONNECT, CLEAR CONNECT TYPE X protocols). The system controller 150 may be configured to communicate according to one or more proprietary and / or standardized wireless communication standards.

[0050] 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 transmitted 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.

[0051] The computing device 160 may be configured to transmit 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 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 (e.g., using wireless protocols such as ZIGBEE, THREAD, NFC, BLUETOOTH, BLUETOOTH LOW ENERGY (BLE), WI-FI, CLEAR CONNECT, CLEARCONNECT TYPE X protocols).

For example, the computing device 160 may be configured to send messages to the system controller 150 over a LAN 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.

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 CCT dimming curve) in response to actuation or input from a user on the touch-sensitive surface.

[0088] 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.

[0089] The control circuit 431 may communicate with one or more output sources 435. The output source 435 may include one or more indicators (e.g., visible indicators such as LEDs) for providing indications (e.g., feedback) to a user. The output source 435 may include a display (e.g., a visible display) for providing information (e.g., feedback) to a user. The control circuit 431 and / or the display may generate a graphical user interface (GUI) generated via software for display on the device 430 (e.g., displayed on a display of the device 430).

[0090] 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 be in bidirectional communication, because 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.

[0091] 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 .

[0092] As described herein, a lighting device (eg, smart bulbs 120a, 120b and / or LED driver 130) may be configured to control the CCT of the accumulated light emitted by the lighting device to be equal to a target color temperature T TRGT A lighting device (e.g., a control circuit of the lighting device) may determine how to mix light emitted by multiple (e.g., two) emitter circuits (e.g., LEDs) of the lighting device so that the CCT 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 the specific color 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 can be based on the color temperature T used to generate 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 amount of drive current that causes the CCT of the accumulated light emitted by the lighting device to be equal to the target color temperature T. TRGTAlternatively, the system may send a signal to the lighting device such that the CCT of the accumulated light emitted by the lighting device is equal to the target color temperature T TRGT The desired lumen value and / or drive current magnitude.

[0093] Furthermore, the lighting device may be configured to adjust the CCT of the light emitted by the lighting device depending on the intensity level. For example, the lighting device may be configured to adjust the current intensity level L of the light emitted by the lighting device to PRES Towards target intensity level L TRGT control, the range of the target intensity level can span the dimming range, for example, at the lower end intensity level L LE (e.g., minimum intensity, such as about 0.1% to 1.0%) and the upper intensity level L HE (eg, maximum intensity, such as approximately 100%), and the lighting device may be configured to adjust the current color temperature T of the accumulated light emitted by the lighting device to the value of PRES Towards target color temperature T TRGT Adjustment, the target color temperature range can be in the cool white temperature CCT CW (e.g., approximately 3100K to 6500K) with warm white CCT WW (e.g., approximately 1500K to 3000K).

[0094] In addition, in some examples, the lighting device can be configured to dim the light according to a color temperature (eg, correlated color temperature) CCT dimming curve according to the target intensity level L TRGT Control target color temperature T TRGT In some cases, when configured with a particular CCT dimming curve, 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 lowered 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 (e.g., CCT values) between the emitter circuits, for example, to provide warm dimming, or vice versa (e.g., cool dimming, as described herein).

[0095] Figure 5 is a diagram depicting one or more lighting devices (e.g., Figure 1 The smart bulbs 120a, 120b and / or LED drivers 130, Figure 2 The lighting device 200, Figure 3 The controllable lighting device 300 and / or Figure 4The plurality of CCT dimming curves may include any combination of a plurality of warm dimming curves, daylight dimming curves, and cool dimming curves, such as Figure 5 For example, the plurality of CCT dimming curves may include a first CCT dimming curve 510 , a second CCT dimming curve 520 , a third CCT dimming curve 530 , and / or a fourth CCT dimming curve 540 . Figure 5 The dimming level d may be based on a square law or linear dimming curve (eg, the dimming level d may be the dimming curve applied to the target intensity level L TRG The CCT dimming curve may be selectable and / or configurable.

[0096] Each CCT dimming curve may be associated with a different mapping of CCT values ​​across a dimming range (e.g., different CCT values ​​for each dimming level across the dimming range). For example, a CCT dimming curve may define a different CCT value for each of the intensity levels (e.g., dimming levels) of a lighting load. For example, the CCT values ​​may vary from 1500 Kelvin (K) to 6500K, while the dimming range may be at a low end intensity level L LE (e.g., minimum intensity, such as about 0.1% to 10.0%) and a high-end intensity level L HE (e.g., a maximum intensity, such as approximately 100%). In some cases, the system may define multiple dimming levels across the dimming range, such as 256 values ​​(0 to 255), although ranges with more or fewer dimming levels may be used. As described in more detail below, the first CCT dimming curve 510, the second CCT dimming curve 520, and the third CCT dimming curve 530 may be defined by CCT values ​​that are at a target intensity level L for the lighting load. TRGT The first CCT dimming curve 510, the second CCT dimming curve 520, and the third CCT dimming curve 530 may be referred to as warm dimming curves. The fourth CCT dimming curve 540 may be defined by a CCT value at a target intensity level L of the lighting load. TRGT The fourth CCT dimming curve 540 may be referred to as a cold dimming curve.

[0097] The use of a warm dimming curve can be useful because the user only has to adjust a single value, namely the intensity, and the control device and / or lighting device can adjust two different characteristics of the emitted light - the intensity and the color temperature. For example, the control device and / or lighting device only needs to send or receive the commanded intensity level, and in response, the control device and / or lighting device can be configured to adjust both the intensity and color temperature values ​​of the emitted light.

[0098] The CCT dimming curve (eg, each CCT dimming curve) may include a CCT range such as CCT RNG and bend value B and / or defined by any combination of predefined characteristics. CCT range CCT RNG High-end CCT value CCT can be defined HE (For example, the maximum CCT value CCT MAX ) and low-end CCT value CCT LE (For example, the minimum CCT value CCT MIN ), for example, CCT RNG =|CCT HE -CCT LE |. High-end CCT value CCT HE Can be the current intensity L of the lighting load PRES At high-end strength level L HE The CCT value of the light emitted when LE Can be the current intensity L of the lighting load PRES At the low end strength level L LE The bend value B can define the CCT value CCT at the high end of the dimming range. HE With low-end CCT value CCT LE The amount of curvature in a line that defines CCT values ​​between . In some examples, the curvature can be a decimal value (e.g., a decimal value between 0 and 1.0).

[0099] The lighting control system can be configured to calculate the intensity of the light across the dimming range (e.g., from the low end intensity level L LE To high-end strength level L HE ) for each dimming level. For example, the lighting control system may calculate the CCT value of each dimming level based on the high-end CCT value CCT of the selected dimming curve. HE , low-end CCT value CCT LE and bend value B to determine (e.g., calculate) the CCT value of the dimming level d. For example, the lighting control system may determine the CCT value of a specific dimming level d based on:

[0100]

[0101] Where CCT[d] is the CCT value at dimming level d, CCT HE It is the high-end CCT value, CCT LE is the low-end CCT value, B is the bend value of the selected dimming curve, and d is the dimming level.

[0102] For example, the first warm dimming curve 510 may be configured to have a high-end CCT value CCT HE , low-end CCT value CCTLE1 、First CCT range CCT RNG1 (For example, where CCT RNG1 =|CCD HE –CCD LE1 |) and the first bending value B1. Figure 5 In the example shown in HE The value can be about 2800K, the low-end CCT value CCT LE1 may be approximately 1600K, and the first CCT range CCT RNG1 When configured with the first warm dimming curve 510 , the lighting device may be configured to use the first bend value B1 across the first CCT range CCT. RNG1 (For example, from the high end CCT value CCT HE To the low end CCT value CCT LE1 ) maps intensity levels to different CCT values. For example, the lighting device may be configured to TRGT Set to high-end intensity level L HE When the CCT value of the lighting load is controlled to be equal to the high-end CCT value CCT HE , when the target intensity level L TRGT Set to low end strength level L LE When the CCT value of the lighting load is controlled to be equal to the low-end CCT value CCT LE1 , and when the target intensity level L TRGT Based on the first bending value B1, the high-end strength level L is set HE With low end strength level L LE When between HE With low-end CCT value CCT LE1 The value between .

[0103] The second warm dimming curve 520 can be adjusted by the high-end CCT value CCT HE , low-end CCT value CCT LE2 , Second CCT range CCT RNG2 (For example, where CCT RNG2 =|CCD HE –CCD LE2 |) and the second bending value B2 is defined. Figure 5 In the example shown in HE Can be about 2800K, low-end CCT value CCT LE2 may be approximately 1700K, and the second CCT range CCT RNG2 It may be about 1100K. Although shown as having the same high-end CCT value CCT as the first dimming curve 510HE , but in some examples, the second dimming curve 520 may have a different high-end CCT value CCT HE When configured with the second warm dimming curve 520 , the lighting device may be configured to use the second bend value B2 across the second CCT range CCT RNG2 (For example, from the high end CCT value CCT HE To the low end CCT value CCT LE2 ) maps intensity levels to different CCT values. For example, the lighting device may be configured to TRGT Set to high-end intensity level L HE When the CCT value of the lighting load is controlled to be equal to the high-end CCT value CCT HE , when the target intensity level L TRGT Set to low end strength level L LE When the CCT value of the lighting load is controlled to be equal to the low-end CCT value CCT LE2 , and when the target intensity level L TRGT Based on the second bending value B2, the high-end strength level L is set HE With low end strength level L LE When between HE With low-end CCT value CCT LE2 The value between .

[0104] The third warm dimming curve 530 can be adjusted by the high-end CCT value CCT HE , low-end CCT value CCT LE3 、The third CCT range CCT RNG3 (For example, where CCT RNG3 =|CCD HE –CCD LE3 |) and the third bending value B3 is defined. Figure 5 In the example shown in HE Can be about 2800K, low-end CCT value CCT LE3 can be about 2250K, and the third CCT range CCT RNG3 It may be about 550K. Although shown as having the same high-end CCT value CCT as the first dimming curve 510 and the second dimming curve 520 HE , but in some examples, the third dimming curve 530 may have a different high-end CCT value CCT HE When configured with the third warm dimming curve 530 , the lighting device may be configured to use the third bend value B3 across the third CCT range CCT RNG3 (For example, from the high end CCT value CCT HE To the low end CCT value CCTLE3 ) maps intensity levels to different CCT values. For example, the lighting device may be configured to TRGT Set to high-end intensity level L HE When the CCT value of the lighting load is controlled to be equal to the high-end CCT value CCT HE , when the target intensity level L TRGT Set to low end strength level L LE When the CCT value of the lighting load is controlled to be equal to the low-end CCT value CCT LE3 , and when the target intensity level L TRGT Based on the third bending value B3, the high-end strength level L is set HE With low end strength level L LE When between HE With low-end CCT value CCT LE3 The value between .

[0105] The fourth dimming curve 540 can be configured by using the high-end CCT value CCT HE , low-end CCT value CCT LE4 、The fourth CCT range CCT RNG4 (For example, where CCT RNG3 =|CCD HE –CCD LE4 |) and the fourth bending value B4 are defined. Figure 5 In the example shown in HE Can be about 2800K, low-end CCT value CCT LE4 can be about 4000K, and the fourth CCT range CCT RNG4 It should be understood that using the fourth dimming curve 540, the CCT value may increase as the intensity level decreases. When configured with the fourth warm dimming curve 540, the lighting device may be configured to use the fourth bending value B4 across the fourth CCT range CCT RNG4 (For example, from the high end CCT value CCT HE To the low end CCT value CCT LE4 ) maps the intensity level to different CCT values. As described above, the fourth dimming curve 540 can be defined by a CCT value, wherein the CCT value is at a target intensity level L of the lighting load. TRGT For example, the lighting device may be configured to increase when the target intensity level L TRGT Set to high-end intensity level L HE When the CCT value of the lighting load is controlled to be equal to the high-end CCT value CCT HE , when the target intensity level L TRGT Set to low end strength level LLE When the CCT value of the lighting load is controlled to be equal to the low-end CCT value CCT LE4 , and when the target intensity level L TRGT Based on the fourth bending value B4, the high-end strength level L is set HE With low end strength level L LE When between HE With low-end CCT value CCT LE4 The value between .

[0106] A lighting control system (eg, lighting control system 100) may allow a user to select any of the CCT dimming curves presented herein, such as Figure 5 The first CCT dimming curve 510, the second CCT dimming curve 520, the third CCT dimming curve 530, or the fourth CCT dimming curve 540 of the embodiment of the present invention. The lighting control system may allow a user to select and / or configure (e.g., customize) their own CCT dimming curve for a lighting device (e.g., smart bulbs 120a, 120b and / or LED driver 130). For example, the lighting control system may include a computing device (e.g., computing device 160), a dimmer (e.g., dimmer 140), and / or a system controller (e.g., system controller 150) that may be configured to allow a user to select and / or configure their own CCT dimming curve for one or more lighting devices.

[0107] In some examples, a lighting control system (eg, a computing device, a dimmer, and / or a system controller) may allow a user to select a high end CCT value CCT HE (For example, or low-end CCT value CCT LE ) and preconfigured curve shapes (e.g., warm dimming curve shapes and / or cool dimming curve shapes, such as Figure 5 ), and the lighting control system can use these selections to configure (e.g., generate) a CCT dimming curve (e.g., a custom CCT dimming curve). In some examples, each preconfigured curve shape can be associated with a CCT range CCT RNG and bend value B. In addition, in some cases, the preconfigured curve shape may be associated with an initial high-end CCT value (such as 2800K). The lighting control system may be based on a CCT range CCT selected by the user. RNG and high-end CCT value CCT HE Determine the low end CCT value CCT LE (For example, CCT for warm or daylight dimming curves LE =CCT HE -CCT RNG , or CCT for cold dimming curveLE =CCT HE +CCT RNG ). The lighting control system can use the selected high-end CCT value CCT of the curve shape HE , low-end CCT value CCT LE and bend value B to generate a CCT dimming curve. For example, the lighting control system may use the bend value B of the selected dimming curve to fit the selected preconfigured dimming curve to the high-end CCT value CCT HE and low-end CCT value CCT LE In this way, the CCT dimming curve can have the same bending value B and CCT range CCT as the preconfigured curve shape. RNG , but with different low-end CCT values ​​CCT LE and high-end CCT value CCT HE (For example, based on a user-selected high-end CCT value CCT HE As described in more detail herein, after creating a CCT dimming curve, the lighting control system may receive a target intensity level L for the lighting load. TRGT , using the CCT dimming curve based on the target intensity level L TRGT (For example, dimming level d) determines the target CCT value CCTT TRGT , and control the lighting load to emit a target intensity level L based on the CCT dimming curve TRGT and target CCT value T TRGT Thus, the systems and methods described herein may allow a user to generate a custom CCT dimming curve using a limited number of user inputs (eg, a high-end CCT value and a selected curve shape).

[0108] FIG. 6A to FIG. 6B 600, 610 are diagrams of example user interfaces for devices used within a lighting control system (e.g., lighting control system 100) configured to receive one or more user inputs that allow a user to generate a custom CCT dimming curve for a lighting device and / or a load control device. The device may be a computing device (e.g., computing device 160 and / or Figure 4 430), a system controller (eg, system controller 160), a load control device (eg, a dimmer, such as Figure 1 As described, the display of the device may include a touch-sensitive surface, and the user interface 600 may be presented on the display such that the actuation areas are configured to receive one or more user inputs in response to user actuation (e.g., touch) at those locations on the display.

[0109] Fig. 6Ais a diagram of an example user interface 600 of an apparatus for use within a lighting control system (e.g., lighting control system 100) configured to receive user input that allows a user to control a lighting load at a high-end intensity level L HE Adjust the current color temperature T of the lighting load PRES , and the lighting load is at the high-end intensity level L HE Choose high-end CCT values ​​for lighting loads.

[0110] Prior to displaying the user interface 600, the device (eg, or other device within the lighting system) may be configured to cause the lighting device to set the current intensity level L of the lighting load to the current intensity level L PRES Set to high-end intensity level L HE (e.g., approximately 100%). When the lighting load is set to the high-end intensity level L HE When the user interface 600 is used, the user interface 600 may prompt the user to adjust the current color temperature T of the lighting load. PRES For example, the user interface 600 may include a GUI that allows the user to increase the current color temperature T of the lighting load. PRES The actuation area 602 allows the user to reduce the current color temperature T of the lighting load. PRES Thus, when the lighting load is emitting the high-end intensity level L HE When the light is at a high-end intensity level L, the user can be configured to use the actuation areas 602, 604 to increase or decrease the color temperature, respectively, which allows the user to HE Once the desired color temperature is identified, the user can actuate the actuation area 606 to confirm that the lighting load is at the high end intensity level L HE The device may store the selected color temperature as a high-end CCT value. Thereafter, the device may send the high-end CCT value to one or more other devices within the lighting system, such as a lighting device, a system controller, or a load control device.

[0111] Figure 6B 6 is a diagram of an example user interface 610 of an apparatus for use within a lighting control system (e.g., lighting control system 100) that is configured to receive one or more user inputs that allow a user to generate a custom CCT dimming curve. The apparatus may be configured to generate one or more graphical user interfaces (GUIs), such as user interface 610, that allow a user to select a curve shape from a plurality of different curve shapes. The plurality of selectable curve shapes may include a warm CCT dimming curve shape, a daylight CCT dimming curve shape, and / or a cool CCT dimming curve shape.

[0112] The user interface 610 may allow a user to select from any combination of curve shapes. For example, the user interface 610 may include an actuation region 612 for selecting a first curve shape (e.g., a first warm dimming curve, such as the first CCT dimming curve 510), an actuation region 614 for selecting a second curve shape (e.g., a second warm dimming curve, such as the second CCT dimming curve 520), an actuation region 616 for selecting a third curve shape (e.g., a daylight dimming curve, such as the third CCT dimming curve 530), and / or an actuation region 618 for selecting a fourth curve shape (e.g., a cool dimming curve, such as the fourth CCT dimming curve 540). Each curve shape may be characterized by a corresponding CCT range and a bend value B.

[0113] The user may select a curve shape by touching one of the actuation areas 612, 614, 616, or 618. The user may confirm the selection of the curve shape by touching the actuation area 620. Thereafter, the device may send the selected curve shape (e.g., the CCT range and bend value B of the selected curve shape) to one or more other devices within the lighting system, such as a lighting device, a system controller, or a load control device. In addition, after selecting the curve shape, but before confirming the curve shape, the user may be configured to adjust the current intensity level L of the lighting load. PRES In order to adjust the current intensity level L of the lighting load across the dimming range PRES The effect that the selected curve shape has on the emitted light output from the lighting load can be visualized at the same time. Thus, the user can visualize the effect of the selected curve shape before confirming the selection.

[0114] Figure 6C 6 is a diagram of an example process 630 for allowing a device in a lighting control system (e.g., lighting control system 100) to allow a user to configure (e.g., generate) a CCT dimming curve (e.g., a custom CCT dimming curve). Process 630 may be performed by a control circuit (e.g., control circuit 431) of one or more devices of the lighting control system, such as a lighting device (e.g., a smart light bulb, such as Figure 1 The smart bulbs 120a and 120b of the lighting control system 100, Figure 2 The lighting device 200, and / or Figure 3 lighting device 300), a mobile device (e.g., a computing device, such as computing device 160 and / or Figure 4 The control circuitry may perform process 630 in response to receiving one or more user inputs. The control circuitry may receive the user inputs via a user interface of the device (eg, indirectly or indirectly).

[0115] Process 630 may begin at 640, for example, in response to receiving a request via a user interface that corresponds to a high-end CCT value CCT HE For example, the control circuit may receive a high-end CCT value selected by a user via a user interface, such as in Fig. 6A In addition, the control circuit may receive a user selection of a curve shape via a user interface, such as in Figure 6B As described herein, the selected curve shape may be related to the bend value B and / or the CCT range CCT RANGE Associated.

[0116] At 642, the control circuit may receive a high-end CCT value CCT HE and selection of a curve shape. For example, as described herein, a user may select one of a plurality of preconfigured curve shapes (e.g., Figure 5 The high-end CCT value CCT corresponds to the curve shape of one of the first dimming curve 510, the second dimming curve 520, the third dimming curve 530 or the fourth dimming curve 540 shown in FIG. HE It can be the current intensity level L of the emitted light PRES At high-end strength level L HE In some examples, a user may control (e.g., adjust) the current color temperature T of light emitted by one or more lighting loads by using a device (e.g., a computing device) of a lighting control system.

[0117] At 644, the control circuit may determine the bend value B and the CCT range CCT based on the selected curve shape. RNG For example, the control circuit may retrieve the bend value B and the CCT range CCT from the memory of the device. RNG Each curve shape is available with CCT range CCT RNG is associated with (eg, defined by) the bend value B. CCT range CCT RNG A CCT dimming curve corresponding to the curve shape may be defined across the dimming range (e.g., at the high end intensity level L HE With low end strength level L LEThe bend value B may define the amount of curvature in the line of CCT values ​​that define the resulting CCT dimming curve across the dimming range. In some examples, bend B may be a decimal value (e.g., a decimal value between 0 and 1.0).

[0118] At 646, the control circuit may determine the value of the high-end CCT based on the CCT value CCT. HE and CCT range CCT RNG Determine (e.g., calculate) the low-end CCT value CCT LE As mentioned above, the high-end CCT value CCT HE Can be selected by the user, and each CCT dimming curve and CCT range CCT RNG The control circuit can be configured to generate a high-side CCT value CCT by HE Subtract CCT range CCT RNG (For example, CCT for warm or daylight dimming curves LE =CCT HE –CCT RNG , or CCT for cold dimming curve LE =CCT HE +CCT RNG ) to determine the low-end CCT value CCT LE Furthermore, although the control circuit receives the high-end CCT value CCT at 642 HE , but in some examples, the control circuit may receive a low-end CCT value CCT at 642. LE And the high end CCT value CCT may be determined at 646 HE .

After generating the customized CCT dimming curve, the control circuit may use the customized CCT dimming curve to configure one or more devices of the lighting control system, such as a load control device (e.g., a dimmer such as dimmer 140, an LED driver such as LED driver 130, etc.) and / or a lighting device (e.g., a smart bulb such as smart bulbs 120a, 120b, etc.). Thereafter, the load control device and / or the lighting device may be controlled according to the customized CCT dimming curve. For example, the lighting device may be configured to adjust the target intensity level L according to the customized CCT dimming curve. TRGT (e.g. dimming level d) to control the target color temperature T TRGT .

[0120] Thus, a device of the lighting control system (eg, a computing device, such as computing device 160 and / or Figure 4 The computing device 430, or a system controller such as the system controller 160, may be configured to generate a CCT dimming curve (e.g., a custom CCT dimming curve) based on limited user input. For example, the computing device may receive a high-end CCT value CCT HE and a selection of a preconfigured curve shape, and based on these inputs, generates a CCT dimming curve. In some examples, the computing device may calculate the current intensity level L of the lighting load. PRES Control to high-end intensity level L HE , and prompting the user to adjust and select the high-end intensity level L, for example, via a display device of the computing device HE The CCT value (e.g., CCT HE ). The computing device may also require the user to select one of a plurality of preconfigured curve shapes. For example, the computing device may present a plurality of preconfigured curve shapes (e.g., via a display device of the computing device) and prompt the user to select a preconfigured curve shape. HE Based on the selection of values ​​and preconfigured curve shapes, the computing device can generate a CCT dimming curve and / or send these values ​​elsewhere to generate a CCT dimming curve by another device of the lighting control system.

[0121] In some examples, a combination of devices may perform process 630. For example, process 630 may be performed by a lighting device. In such an example, the lighting device may receive a high-end CCT value CCT from a computing device such as a mobile phone. HE and the selection of the curve shape, and the remaining steps 644 to 648 may be performed at the lighting device. Alternatively, a computing device such as a mobile phone may perform process 630. In such a case, after calculating the low-end CCT value, the computing device may generate a CCT dimming curve and send the CCT dimming curve to the lighting device, or may send a subset of a high-end CCT value, a low-end CCT value, a CCT range CCT value, and a CCT dimming curve. RANGE and / or bending value B.

[0122] As another example, in some cases, the device may perform process 630 and set a CCT dimming curve (e.g., a subset of high-end CCT values, low-end CCT values, CCT range CCT values, etc.) to the CCT value. RANGE The system controller may generate a CCT dimming curve using the received CCT dimming curve data and store the CCT dimming curve in a memory.

In such an example, the lighting control system may not require a user to select a preconfigured CCT dimming curve, but may allow the user to select a plurality of (e.g., three) different sets of CCT values ​​and intensity levels for one or more lighting loads. The lighting control system may determine a bend value B based on the plurality of CCT values ​​and intensity levels, and may generate a custom CCT dimming curve based on the plurality of CCT values ​​and intensity levels and the bend value B.

[0137] Fig.7D7 is a diagram of an example process 730 for allowing a device in a lighting control system (e.g., lighting control system 100) to allow a user to configure (e.g., generate) a CCT dimming curve (e.g., a custom CCT dimming curve). Process 730 may be performed by a control circuit (e.g., control circuit 431) of one or more devices of the lighting control system, such as a lighting device (e.g., a smart light bulb, such as Figure 1 The smart bulbs 120a and 120b of the lighting control system 100, Figure 2 The lighting device 200, and / or Figure 3 lighting device 300), a mobile device (e.g., a computing device, such as computing device 160 and / or Figure 4 The control circuitry may perform process 730 in response to receiving one or more user inputs. The control circuitry may receive the user inputs via a user interface of the device.

[0138] Process 730 may begin at 740, for example, in response to receiving a user input corresponding to a selection of a custom CCT dimming curve selection via a user interface. At 742, the control circuit may receive a high-end CCT value CCT HE and low-end CCT value CCT LE For example, the control circuit may be configured to calculate the current intensity level L of the lighting load. PRES At high-end strength level L HE (e.g., approximately 100% intensity level) when receiving a high end CCT value CCT HE selection, and the current intensity level L of the lighting load PRES At the low end strength level L LE (e.g., about 0.1% to 10.0% of the intensity level) when receiving a low-end CCT value CCT LE For example, the high-end intensity level L HE and low-end strength level L LE may be set by the lighting load and / or may be selectable by the user. For example, the control circuit may receive a high-end CCT value CCT selected by the user via a user interface. HE , such as in Fig. 7A and receiving a low-end CCT value CCT selected by a user via a user interface LE , such as in Figure 7B described in the context of.

[0139] In some examples, the control circuit may determine the current intensity level L of the lighting load. PRES Set to high-end intensity level L HE , allowing the user to adjust the CCT value of the emitted light, and receive a user-defined setting for the high-end intensity level LHE When finding the CCT value they like, users are interested in the high-end CCT value CCT HE Similarly, the control circuit can determine the current intensity level L of the lighting load. PRES Set to low-end intensity level L LE , allowing the user to adjust the CCT value of the emitted light, and receiving the user's low-end intensity level L LE When finding the CCT value they like, the user's preference for the low-end CCT value CCT LE Thus, the control circuit may receive a confirmation (e.g., selection) for the high-end intensity level L HE High-end CCT value CCT HE and for low-end strength level L LE The low end CCT value CCT LE .

[0140] At 744, the control circuit may receive the intermediate CCT value CCT INT For example, the control circuit may allow the user to select an intermediate intensity level L INT , and when the lighting load is emitting an intermediate intensity level L INT The control circuit allows the user to adjust and select the intermediate intensity level L INT The median CCT value CCT INT For example, the control circuit may receive an intermediate CCT value selected by a user via a user interface, such as in Figure 7C In some examples, the control circuit may INT The system may be limited (eg, constrained) to a limited intensity range of the lighting load (eg, between 10% and 30% intensity levels). That is, in some examples, the system may require the user to select an intermediate intensity level L. INT (e.g. dimming level d) Select an intermediate CCT value CCT within a predefined range INT , such as near the low end (e.g., between 10% and 30% intensity levels). In addition, in some examples, the control circuit may have a predefined intermediate intensity level L INT , and the user may not be allowed to select or adjust the intermediate intensity level L INT .

[0141] Thus, each of the plurality of CCT values ​​may be associated with an intensity level (eg, a different intensity level). HE Compatible with high-end intensity level L for lighting loads HE Related, low-end CCT value CCT LE The low-end intensity level L of the lighting load can be LE associated, and the intermediate CCT value CCTINT Suitable for lighting loads with intermediate intensity levels L INT Intermediate CCT value CCT INT Can be at the low end CCT value CCT LE With customized high-end CCT value CCT HE Between, and the intermediate intensity level L INT Available at low end strength level L LE With high-end strength level L HE between.

[0142] At 746, the control circuit may determine the value of the high-end CCT based on the CCT value CCT. HE , high-end strength level L HE , low-end CCT value CCT LE , low end strength level L LE , intermediate CCT value CCT INT and intermediate intensity level L INT Determine a bending value B of the dimming curve. For example, the control circuit may fit the CCT dimming curve to the selected CCT value based on the intensity level associated with each CCT value (e.g., using Equation 1 defined herein), and based on the fit, the control circuit may determine the bending value B of the dimming curve. For example, the control circuit may determine the bending value B that causes the dimming curve to be at a high-end intensity level L when the lighting load is at a high-end intensity level L. HE High CCT value CCT HE Initially, the lighting load is at the low end intensity level L LE CCT LE end, and when the lighting load is at the intermediate intensity level L INT When passing through the intermediate CCT value CCT INT For example, referring to Equation 1, and for example, knowing that CCT HE and CCT LE , and the dimming level d is based on the intermediate intensity level L INT Thus, in some examples, the bending value B can be obtained by setting d equal to the intermediate strength level L INT And let CCT[d] be equal to the intermediate CCT value CCT INT Come for solution.

[0143] At 748, the control circuit may use the low-end CCT value CCT LE , high-end CCT value CCT HE and a bend value B (e.g., and in some examples, also based on the low end strength level L LE and high-end strength level L HE) generates a CCT dimming curve. In this way, the control circuit can generate a CCT dimming curve based on the user's selection of three CCT values, where each CCT value is associated with a different intensity level across the dimming range. After generating the CCT dimming curve, the control circuit can use the CCT dimming curve to configure one or more devices of the lighting control system, such as a load control device (e.g., a dimmer such as dimmer 140, an LED driver such as LED driver 130, etc.) and / or a lighting device (e.g., a smart bulb, such as smart bulbs 120a, 120b, etc.). Thereafter, the load control device and / or the lighting device can be controlled according to the CCT dimming curve. For example, the lighting device can be configured to adjust the target intensity level L based on the CCT dimming curve. TRGT To control the target color temperature T TRGT .

[0144] Thus, a device of the lighting control system (eg, a computing device, such as computing device 160 and / or Figure 4 The computing device 430, or a system controller such as the system controller 160, may be configured to generate a custom CCT dimming curve based on limited user input. For example, the computing device may receive a plurality of CCT values ​​(e.g., such as a high-end CCT value CCT HE , low-end CCT value CCT LE and the intermediate CCT value CCT INT ), and based on these CCT values ​​and the corresponding intensity levels associated with each CCT value, generates a customized CCT dimming curve. In some examples, the computing device may calculate the current intensity level L of the lighting load. PRES Control to high-end intensity level L HE , and prompting the user to adjust and select the high-end intensity level L, for example, via a display device of the computing device HE The CCT value (e.g., CCT HE ). The computing device can calculate the current intensity level L of the lighting load PRES Control to low end intensity level L LE , and prompting the user to adjust and select the low-end intensity level L, for example, via a display device of the computing device LE (For example, CCT LE The computing device may allow the user to select an intermediate intensity level L INT , control the lighting device to emit an intermediate intensity level L INT and prompting the user, for example via a display device of the computing device, to adjust and select the intermediate intensity level L INT (For example, CCT INT ) CCT value. Based on the high-end CCT value CCT HE , low-end CCT value CCT LE , intermediate CCT value CCTINT and the corresponding intensity level for each CCT value (e.g., L HE , L LE , L INT ), the computing device may generate a custom CCT dimming curve and / or send these values ​​elsewhere for generation of a custom CCT dimming curve by another device of the lighting control system.

[0145] Figure 8 8 is a diagram of an example process 800 for allowing a device in a lighting control system (e.g., lighting control system 100) to allow a user to generate a custom CCT dimming curve. Process 800 may be performed by a control circuit (e.g., control circuit 431) of one or more devices of the lighting control system, such as a mobile device (e.g., a computing device, such as computing device 160 and / or Figure 4 The control circuit may perform process 800 in response to receiving one or more user inputs. The control circuit may receive the user input via a user interface of the device. Process 800 may be implemented, for example, on a mobile device, and the mobile device may be configured to receive user input corresponding to the selection of a custom CCT dimming curve via a user interface of the mobile device. After the mobile device generates the custom CCT dimming curve, the mobile device may send data related to the custom CCT dimming curve to a load control device and / or a lighting device that may implement the custom CCT dimming curve.

[0146] Process 800 may begin at 810, for example, in response to receiving a user input corresponding to a selection of a custom CCT dimming curve selection via a user interface. At 812, the control circuit may receive a high-end CCT value CCT via one or more user inputs (e.g., via a user interface of a mobile device). HE and selection of predefined curve shapes. High end CCT value CCT HE At the target intensity level L TRGT Set to high-end intensity level L HE The control circuit may include a plurality of preconfigured CCT dimming curves for selection (e.g., Figure 5 Dimming curves 510, 520, 530, 540).

[0147] At 814, the control circuit may determine the bend value B and the CCT range CCT based on the selected curve shape (eg, from a memory of the mobile device). RNG As described herein, the control circuit may be configured with a plurality of preconfigured curve shapes (e.g., Figure 5The CCT dimming curves 510, 520, 530, 540 are corresponding to the curve shapes), wherein each curve shape can be related to the CCT range CCT RNG is associated with (eg, defined by) the bend value B. CCT range CCT RNG A CCT dimming curve corresponding to the curve shape may be defined across the dimming range (e.g., at the high end intensity level L HE With low end strength level L LE The bend value B may define the amount of curvature in the line of CCT values ​​that define the resulting CCT dimming curve across the dimming range. In some examples, the bend may be a decimal value (e.g., a decimal value between 0 and 1.0).

[0148] At 816, the control circuit may select a high-end CCT value CCT based on the value selected by the user. HE and the CCT range of the selected curve shape CCT RNG Determine (e.g., calculate) the low-end CCT value CCT LE (For example, CCT for warm or daylight dimming curves LE =CCT HE –CCT RNG , or CCT for cold dimming curve LE =CCT HE +CCT RNG ). Low-end CCT value CCT LE At the target intensity level L TRGT Set to low end strength level L LE (eg, a minimum intensity level, such as an intensity level of approximately 0.1% to 10.0%).

[0149] At 818, the control circuit may initialize the dimming level d to an initial value (eg, corresponding to the low-end intensity level L LE The corresponding low-end value or high-end intensity level L HE For example, the control circuit may define multiple dimming levels across the dimming range, such as 256 values ​​(0 to 255), but a range with more or fewer dimming levels may be used. For example, the control circuit may initialize the dimming level d to a low-end value (e.g., zero), and may determine the current intensity L of the lighting load. PRES Set to low end strength level L LE (For example, the CCT value is set equal to the low end CCT value CCT determined at 816 LE ) is the CCT value used.

[0150] The control circuit may calculate a CCT value for (eg, each) dimming level across a dimming range (eg, from a low-end value to a high-end value). For example, at 820, the control circuit may calculate a CCT value for (eg, each) dimming level based on the high-end CCT value CCT HE , low-end CCT value CCT LE The CCT value of the dimming level d is determined (e.g., calculated) by the bending value B of the selected dimming curve. For example, the control circuit may determine the CCT value of a specific dimming level d based on:

[0151]

[0152] Where CCT[d] is the CCT value at dimming level d, CCT HE is the high-end CCT value (e.g., from 812), CCT LE is the low-end CCT value (eg, from 816 ), B is the bend value of the selected dimming curve (eg, from 814 ), and d is the dimming level (eg, from 818 ).

[0153] At 822, the control circuit may store the CCT value for the dimming level d in a memory. At 824, the control circuit may determine whether the dimming level d is equal to the final dimming level d. FINAL (eg, a high end value, such as a dimming level of 255). If at 824 the dimming level d is not equal to the final dimming level d FINAL , the control circuit may increase the dimming level d by one and return to 820. For example, in some examples, the system may define multiple dimming levels across the dimming range, such as 256 values ​​(0 to 255). In such examples, the control circuit may set the low-end CCT value CCT to LE is associated with a dimming level d of 0, and makes the high-end CCT value CCT HE is associated with a dimming level d of 255. In such examples, the control circuit may set the dimming level d equal to 1 when the control circuit first enters 820. The control circuit may be configured to increase the dimming level from 1 to 254 using 820 to 826 to determine (e.g., calculate) the CCT value for each dimming level d from 1 to 254. Alternatively, in some examples, process 800 may initialize the dimming level to the high end at 818 and may subtract 1 from the dimming level d at 826 until the dimming level is equal to the low end dimming level at 824.

[0154] If the control circuit determines at 824 that the dimming level d is equal to the final dimming value d FINAL, the control circuit may send the CCT values ​​at various dimming levels across the dimming range to one or more load control devices and / or lighting loads in the lighting control system. In some cases, the control circuit may send a table including a mapping of CCT values ​​to dimming levels across the entire dimming range to one or more load control devices and / or lighting devices. For example, the control circuit may determine (e.g., calculate) a CCT value (e.g., a different CCT value) for each dimming level across the dimming range, where, for example, the low-end CCT value CCT LE with the minimum dimming level (e.g., with the low-end intensity level L LE The corresponding low-end value) is associated, and the high-end CCT value CCT HE With the final dimming level d FINAL (For example, with high-end intensity level L HE Thus, the control circuit can be configured to generate a custom CCT dimming curve using process 800.

[0155] After the load control device and / or the lighting load receives the CCT values ​​at various dimming levels across the dimming range, the load control device and / or the lighting load may be configured to convert the current intensity level L of the light emitted by the lighting device to PRES Towards target intensity level L TRGT Control and set the current color temperature T of the accumulated light emitted by the lighting device PRES Towards target color temperature T TRGT Adjust the target color temperature T TRGT Based on the current intensity level L PRES Thus, the load control device and / or lighting load may be configured to use a custom CCT dimming curve generated using process 800 according to the target intensity level L TRGT Control target color temperature T TRGT .

[0156] In some examples, a device of the lighting control system (e.g., a mobile device such as computing device 160) can be configured to send limited information related to the customized CCT dimming curve to the load control device and / or the lighting load. For example, the device can be configured to send a high-end CCT value CCT HE , bending value B and CCT range CCT RNGThe CCT dimming curve may be sent to the lighting device, and the lighting device may calculate a custom CCT dimming curve. The transmission of a limited amount of information may not only save transmission overhead, but may also allow the custom CCT dimming curve to be updated more easily and / or more frequently (e.g., periodically throughout the day based on the time of day and / or day of the year). For example, the CCT dimming curve may be adjusted based on a scene selected by a user (e.g., different CCT dimming curves may be associated with different scenes). For example, an entertainment scene may be associated with a light having a low-end intensity L close to the low-end intensity L. LE The reading scene may be associated with a warm CCT dimming curve (eg, dimming curve 510) having a lower CCT value near the low end intensity L LE The active scene may be associated with a warm CCT dimming curve (e.g., dimming curve 530) for a higher CCT value, and the active scene may be associated with a cool dimming curve (e.g., dimming curve 540).

High end CCT value CCT HE At the target intensity level L TRGT Set to high-end intensity level L HE (e.g., maximum intensity, such as approximately 100%). Although the control circuit receives a high-end CCT value CCT at 912 HE, but in some examples, the control circuit may receive a low-end CCT value CCT at 912 LE (For example, and in process 920 the control circuit may then calculate the high end CCT value CCT at 934 HE ).
