[0001] Related applications

[0002] This application claims the benefit of U.S. Provisional Patent No. 62 / 899,166, filed September 12, 2019, entitled “CircadianLighting in a Diverse Home Automation System”, the contents of which are incorporated herein by reference in their entirety. Background Technology Technical Field

[0004] This disclosure generally relates to device control, and more specifically to an architecture for implementing circadian lighting in a home automation system having a variety of lighting devices with different capabilities and control methods.

[0005] Background Information

[0006] Research shows that humans and other animals have evolved "built-in clocks" that regulate the timing of biological processes relative to the day / night cycle. These "clocks" are called circadian rhythms. While circadian rhythms are self-regulating in the natural environment, modern lighting has been shown to disrupt them, delaying melatonin production and having other adverse health effects. Research shows that strong light from lighting devices, particularly blue light found in high Kelvin (e.g., 4600K-6500K) "daylight" lighting, disrupts circadian rhythms. Strong light in this range may mimic sunlight in the middle of the day, thus confusing the body's perception of the day / night cycle.

[0007] To address this issue, significant efforts have recently been made to implement circadian rhythmic lighting in structures (e.g., residential or commercial structures), where the intensity (i.e., luminance) and / or color temperature of lighting fixtures are modulated throughout the day to simulate the day / night cycle. Such circadian rhythmic lighting can minimize disruption to the circadian rhythm and avoid adverse health effects. However, implementing circadian rhythmic lighting presents numerous challenges.

[0008] One challenge is that many existing structures possess a diverse set of lighting devices with varying capabilities and different ways of controlling them. For example, some lighting devices may have both controllable color temperature and intensity. Others may only have controllable intensity. Similarly, some lighting devices can be controlled via digital lighting control protocols (e.g., Digital Multiplexing (DMX)). Others can be controlled via simple DC voltage control signals (e.g., 0-10 volts (V)). Still other lighting devices may rely on external devices to modify their output, such as external devices that implement phase-cut dimming of the high-voltage power supplied to the lighting devices. Replacing all lighting devices in a structure with those having the same capabilities may be prohibitively expensive or otherwise impractical. Often, the practical result is that circadian rhythm lighting is implemented only on a subset of the lighting devices in the structure, while the rest remain unchanged. This significantly reduces the benefits of implementing circadian rhythm lighting for the others.

[0009] Another challenge is that many existing efforts to achieve circadian lighting are largely static and do not respond to current lighting conditions in the outdoor environment. Some simple systems may not respond at all to seasonal changes in lighting conditions, such as changes in sunrise and sunset times. More complex systems may account for such seasonal changes to some extent, but only approximatedly. For example, a user might be prompted to enter the date and latitude and longitude data, which can be used to access tables of approximate sunrise and sunset times for a general area. However, such approximations do not apply to the precise location of structures there and local conditions (e.g., tall trees, mountains, etc.), which can affect perceived sunrise or sunset times (e.g., causing lighting to be perceptibly stronger or weaker at times slightly different from official sunrise or sunset times). Furthermore, existing systems generally do not account for changes in current lighting conditions in the outdoor environment that are independent of seasonal variations. For example, current weather (e.g., cloud cover, rain, fog, etc.) can significantly alter lighting conditions in the outdoor environment. Existing systems typically do not respond to such changes. As a result, existing systems often produce effects that appear unnatural and disconnected from the outside world, thereby diminishing the user experience, the likelihood of adoption, and the benefits of circadian lighting.

[0010] Therefore, there is a need for an architecture for implementing circadian lighting in home automation systems with diverse lighting devices that have different capabilities and control methods that are more responsive and dynamic. Summary of the Invention

[0011] In various embodiments, an architecture is provided for implementing circadian rhythmic lighting in a home automation system with diverse lighting devices having different capabilities and control methods. This architecture utilizes outdoor sensors to capture current intensity and color temperature data of the outdoor environment. The color temperature and intensity from a user-created circadian rhythmic lighting curve are dynamically adjusted based on the current intensity and color temperature data of the outdoor environment to approximate ongoing changes. The diverse lighting devices are controlled based on the dynamically adjusted temperature and intensity.

[0012] More specifically, in one embodiment, the circadian rhythm lighting (also known as "daylight mode") configuration user interface is provided by a control application (app) executing on a control device (e.g., a remote control, mobile device, host controller, or other electronic device). Using the configuration user interface, the user selects desired color temperature and intensity for one or more time periods, for example, selecting different color temperature and intensity for each of several different predefined time periods (e.g., morning, daytime, evening, and night) that define the circadian rhythm lighting curve. An outdoor sensor collects current intensity and color temperature data for lighting in the outdoor environment. The circadian rhythm lighting curve color temperature and intensity, the current intensity and color temperature from the outdoor sensor, and the current time from the system clock are provided to a dynamic color manager process executing on the host controller. The dynamic color manager process uses a research-based lighting algorithm to combine the circadian rhythm lighting curve color temperature and intensity applicable to the current time with the current color temperature and intensity from the outdoor sensor (e.g., simulating the current color temperature, intensity, and intensity in the outdoor environment) to produce an optimal color temperature and dimming value for the current time. As lighting conditions in the outdoor environment change, the dynamic color manager process updates the optimal color temperature and / or dimming value to change dynamically accordingly.

[0013] The dynamic color manager process provides the optimal color temperature and dimming values ​​to the service request manager process, which also executes on the host controller. The service request manager process determines whether circadian rhythm lighting (also known as "daylight mode") is currently enabled in the room, and if so, provides the current optimal color temperature and dimming values ​​to the lighting control process, which also executes on the host controller. The lighting control process translates the current optimal color temperature and dimming values ​​into one or more sets of individual lighting commands and sends these commands to one or more lighting control devices in the room, such as lighting controllers (e.g., DMX or 0-10V), wireless gateway devices (e.g., Bluetooth Low Energy (BLE) gateways), non-wireless gateway devices (e.g., wall-mounted dimmers or plug-in dimmers), panel bridge controllers, and the like. The lighting control equipment converts received lighting command sets into digital control values, low-voltage analog signals, or modulated high-voltage power (e.g., RBGW values, 0-10V dimming and color signals, high-voltage phase switching, etc.). Depending on the situation, it can specify the capabilities of diverse lighting devices in the room (e.g., wireless lighting devices (e.g., DMX or 0-10V), line-level lighting devices, etc.), and such commands, values, or power are sent to the corresponding lighting devices. Through the conversion performed by the lighting control process, the current color temperature and dimming value of each room are converted into approximate values ​​achievable under the different capabilities of the lighting devices in a given room.

[0014] It should be understood that various additional features and alternative embodiments can be implemented. This summary is intended only as a brief introduction to the reader and does not indicate or imply that the examples mentioned herein cover all aspects of the invention or any necessary or essential aspects thereof.

[0023] Example Home Automation System Architecture

[0024] Figure 1 This is a block diagram of an example architecture 100 for a home automation system that implements circadian lighting, featuring a variety of lighting devices with different capabilities and control methods. At the heart of the system is a host controller 110 coupled to a wired local area network (LAN) 105 (e.g., an Ethernet LAN), which in turn is coupled to an access point (AP) 107 (e.g., a Wi-Fi AP) providing a home WLAN.

[0025] The host controller 110 may include hardware components such as processors, memory, and storage devices that share and execute host software (including a dynamic color manager, service request manager, lighting control procedures, and other software), and is configured to monitor and control the operation of devices 120-156; provide UI interpretation, system administration, and monitoring; perform synchronization with cloud service 180; provide activity logging services; provide activity prediction services; and / or provide other types of functionality. The host controller 110 may also maintain a home database in its storage device, which stores configuration information including information about devices 120-156 controlled by the home automation system and their capabilities, as well as information about remote controls 150, mobile devices 160, and other electronic devices 170 that provide a graphical user interface (GUI) for controlling devices 120-156.

[0026] Devices 120-156 controlled by the home automation system can take many different forms. Device 156 may include audio and video devices 124 (collectively referred to as A / V devices) (not shown), such as display devices (e.g., televisions, monitors, etc.), A / V device controllers, media servers, audio amplifiers, cable boxes, etc. Devices 120-156 may also include motor- and / or relay-operated devices (e.g., curtain controllers, electronic curtains, electronic door locks, etc.), security devices, heating, ventilation, and cooling (HVAC) equipment, etc. (not shown).

[0027] Devices 120-156 may further include lighting devices with various capabilities and control methods. Some lighting devices support control of both color temperature and intensity. Such lighting devices may include lighting controllers coupled to wired LAN 105 via a wired connection (e.g., Ethernet connection), which control them by sending digital control values ​​or low-voltage signals to individual luminaires and / or lighting fixtures. For example, a DMX lighting controller 134 may be coupled to wired LAN 105 via a wired connection (e.g., Ethernet connection) and control individual lighting devices 136 (e.g., luminaires) coupled to wired LAN 105 via a wired connection that transmits RBGW values. Similarly, a 0-10V lighting controller 138 may be coupled to wired LAN 105 via a wired connection (e.g., Ethernet connection) and to individual luminaires and / or lighting fixtures 140 coupled to wired LAN 105 via a wired connection that transmits 0-10V dimming and color signals. Such lighting devices may include lighting controllers that support wireless communication. For example, a gateway device 142, such as a wireless lighting module 144 and a wireless keyboard 146, can receive commands via a WLAN (e.g., Wi-Fi) and control the individual wireless lights and / or lighting fixtures 148 by sending RBGW values ​​over a wireless personal area network (WPAN) (e.g., BLE).

[0028] Other lighting devices may support intensity-only control. Such lighting devices may include lighting controllers coupled to a wired LAN 105 via a wired connection (e.g., an Ethernet connection) that control individual luminaires and / or lighting fixtures. For example, a panel bridge controller 124 and a circuit breaker panel 126 equipped with a matching circuit breaker 127 can control individual lighting devices 128 (e.g., luminaires) coupled thereto by sending modulated high-voltage power (e.g., high-voltage phase cut). Channel dimming values ​​can be passed between the panel bridge controller 124 and the matching circuit breaker 127 using a WPAN (e.g., BLE). Similarly, non-gateway devices 150, such as wall-mounted dimmers 152 and plug-in dimmers 154, can receive control commands via a WLAN (e.g., Wi-Fi) and control individual wireless lighting devices, such as luminaires 128 and lighting fixtures 156, by sending modulated high-voltage power (e.g., high-voltage phase cut).

[0029] The lighting equipment can be controlled by an interface device, such as a keyboard 132 coupled to a keyboard controller 130 or a wireless keyboard 146. Additionally, a remote control 150, a mobile device 160, or another electronic device 170 can be utilized. The remote control 150 may include a touch-sensitive display, physical buttons, a WLAN interface (e.g., a Wi-Fi interface), a WPAN adapter (e.g., a BLE adapter), a processor, memory, and a storage device that stores and executes a control app configured to interface with a host controller 110 and a cloud service 180. Among other functionalities, the control app on the remote control 150 may present a circadian rhythm lighting (“daylight mode”) configuration user interface with a screen for configuring circadian rhythm lighting, and an additional user interface screen for controlling a room with configured circadian rhythm lighting. In some cases, the remote control 150 may communicate with an interconnect device 120, such as an infrared (IR) transmitter.

[0030] In addition, mobile device 160 may include a touch-sensitive display, a WLAN interface (e.g., a Wi-Fi interface), a WPAN adapter (e.g., a BLE adapter), a processor, memory, and a storage device that stores and executes control app 162, which is configured to interface with host controller 110 and / or cloud service 180. Among other functionalities, the control app on mobile device 160 may in particular present a circadian rhythm lighting (“daylight mode”) configuration user interface with a screen for configuring circadian rhythm lighting, and an additional user interface screen for controlling a room with configured circadian rhythm lighting.

[0031] Alternatively, a tablet computer, a dedicated touchscreen unit, or other electronic device 170 may be used. Electronic device 170 may include a display screen (e.g., touch-sensitive, non-touch-sensitive, etc.), input devices, a WLAN interface (e.g., a Wi-Fi interface), a WPAN adapter (e.g., a BLE adapter), a processor, memory, and a storage device that stores and executes a control app 162 configured to interface with host controller 110 and / or cloud service 180. Among other functionalities, the control app on electronic device 170 may present a circadian rhythm lighting (“daylight mode”) configuration user interface with a screen for configuring circadian rhythm lighting, and additional user interface screens for controlling a room with configured circadian rhythm lighting.

[0032] Some devices (e.g., host controller 110, mobile device 160, another electronic device 170, etc.) can communicate with cloud service 180 via Internet 175. Cloud service may include host application programming interfaces (APIs) and mobile APIs, providing remote access to home automation control; persistent backup of home databases, such as storing data in a configuration database; interfaces to third-party infrastructure, such as via third-party adapters; user profiles and usage tracking, such as storing data in a user database; mechanisms for over-the-air updates; host crash reporting; license management; and a variety of other functionalities.

[0033] Figure 2This is a block diagram illustrating an example arrangement of circadian rhythm lighting for a home automation system with diverse lighting devices having different capabilities and control methods. In the circadian rhythm lighting (“daylight mode”) configuration user interface provided by a control app running on the control device, the user enters their desired color temperature and intensity selection for predefined time periods (e.g., morning, daytime, evening, and night) that define the circadian rhythm lighting curve, and transmits this to a dynamic color manager process 220 executing on the host controller 110. An outdoor sensor 112 collects current intensity and color temperature data (e.g., Kelvin values) of lighting in the outdoor environment, which, along with the current time from the system clock 210, is also provided to the dynamic color manager process 220 executing on the host controller 110. The dynamic color manager process 220 uses a research-based lighting algorithm to combine the color temperature and intensity from the circadian rhythm lighting curve applicable to the current time with the current color temperature and intensity from the outdoor sensor 112 (e.g., simulating the current color temperature, intensity, and intensity in the outdoor environment) to produce an optimal color temperature and dimming value for the current time. For example, if the current color temperature and / or intensity from outdoor sensor 112 is lower than the color temperature and intensity from a circadian rhythm lighting curve applicable to the current time, the dynamic color manager process 220 can decrease the color temperature and / or intensity of the circadian rhythm lighting curve (e.g., match the color temperature and / or intensity from outdoor sensor 112, or move one or more increments closer to the color temperature and / or intensity from outdoor sensor 112). Similarly, if the current color temperature and / or intensity from outdoor sensor 112 is higher than the color temperature and intensity of the circadian rhythm lighting curve applicable to the current time, the dynamic color manager process 220 can increase the color temperature and / or intensity of the circadian rhythm lighting curve (e.g., match the color temperature and / or intensity from outdoor sensor 112, or move one or more increments closer to the color temperature and / or intensity from outdoor sensor 112). In effect, as lighting conditions in the outdoor environment change, the dynamic color manager process 220 updates the optimal color temperature and / or dimming value to dynamically change accordingly.

[0034] The dynamic color manager process 220 provides optimal color temperature and dimming values ​​to the service request manager 230, which executes on the host controller 110. For each room, the service request manager 110 determines whether circadian rhythm lighting (also known as "daylight mode") is currently enabled in the room, and if so, provides the optimal color temperature and dimming values ​​to the lighting control process 240, which also executes on the host controller 110. The lighting control process 240 translates the current optimal color temperature and dimming values ​​into one or more sets of individual lighting commands and sends these commands to one or more lighting control devices in the room. Depending on the lighting control device, the different individual lighting commands can be sent in different ways. For example, looking at lighting devices that support color temperature and intensity: the load address, Kelvin value, and dimming level can be sent to the DMX lighting controller 134 and the 0-10V lighting controller 138 via Ethernet, and the load address, Kelvin value, and RGBW value can be sent to the gateway device 142 via Ethernet and WLAN (e.g., Wi-Fi). With an eye toward supporting intensity-only lighting devices: load addresses and dimming levels can be sent to panel bridge controller 124 via Ethernet, and load addresses and dimming levels can be sent to wall box dimmer 152 and plug-in dimmer 154 via Ethernet and WLAN (e.g., Wi-Fi).

[0035] The lighting control device converts received lighting command sets into control values, low-voltage signals, or modulated high-voltage power, and, depending on the situation, can provide the ability to send them to diverse lighting fixtures in each room to individual lighting devices. For example, looking at lighting devices that support color temperature and intensity: DMX lighting controller 134 converts lighting commands into RGBW values, which are sent to DMX lighting device 136 via a wired link; 0-10V lighting controller 138 converts lighting commands into 0-10V dimming and color signals, which are sent to lighting device 140 via a wired link; and gateway device 142 converts lighting commands into RGBW values, which are sent to wireless lighting device 148 via WPAN (e.g., BLE). Focusing on supporting only intensity lighting fixtures: Panel bridge controller 124 translates lighting commands into channel dimming values, which are sent via WPAN (e.g., BLE) to a matching circuit breaker 127, which provides modulated high-voltage power (e.g., high-voltage phase cut) to lighting fixture 128. Wall-mounted dimmer 152 and plug-in dimmer 154 translate lighting commands into modulated high-voltage power (e.g., high-voltage phase cut) supplied to lighting fixture 128. Through the conversion performed by the lighting control process, the current color temperature and dimming value are translated into approximate values ​​achievable under different lighting fixture capabilities in a given room.

[0036] Figure 3A-3JThese are a series of sample screenshots showing the configuration user interface provided by a control app that can be executed on a remote control 150, a mobile device 160, or another electronic device 170. Figures 3A-3B In the configuration, the user interface prompts the user to select a room to enable circadian lighting (also known as "daylight mode"). It also prompts the user to select the desired color temperature and intensity for predefined time periods (e.g., morning, daytime, evening, and night) to define the circadian lighting curve. Figure 3C-3D In the interface, users select the color temperature and intensity for the morning time period. Users can also select a celestial reference and time offset, or a specific clock time, thus defining when the morning time period begins. Figure 3E In the settings, users select the color temperature and intensity for daytime hours. Users can also select a specific clock time to define when the daytime begins. Figure 3F In the settings, users select the color temperature and intensity for the evening period. Users can also select a specific clock time to define when the evening period begins. Figure 3G-3I In the process, the user selects the color temperature and intensity for a specific nighttime period. The user can also select a celestial reference and time offset, or a specific clock time, thus defining when the nighttime period begins. In some cases, working in conjunction with the Dynamic Color Manager process 220, the control app can obtain the planned optimal color temperature and dimming values. Such planned optimal color temperature and dimming values ​​can be based in part on historical or generalized outdoor environmental data. Figure 3J The system displays a chart to the user, indicating a preview of the planned optimal color temperature and dimming values ​​for the room throughout the day. It also offers the option to preview the planned optimal color temperature and dimming values ​​for circadian rhythm lighting in an actual room at an accelerated pace (e.g., 24 hours condensed to 1 minute). Figure 3K The configuration of the diurnal rhythm lighting is now complete.
