Abstract: A remote control device may be configured to transmit command messages based on user interactions. The remote control device may receive an indication of a user interaction and transmit a command message based on the indication of the user interaction. The command message may include a command to adjust an intensity level of a lighting device and a fade period. The fade period may include the period of time over which the lighting device is to transition to the intensity level. After a transmission interval period of time from when the command message was transmitted elapses and based on a subsequent user interaction, the remote control device may transmit another command message, which may include a command for the lighting device to adjust to another intensity level over the fade period. The fade period may be longer than the transmission interval.

Abstract: A load control device may be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.

Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.

Abstract: A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and controller devices, such as a remote control device configured to transmit digital messages for controlling the lighting load via the load control device. The remote control device may communicate with the lighting devices via a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages as unicast messages or multicast messages based on the type of user interface event detected. The remote control device, or other master device, may synchronize and/or toggle an on/off state of lighting devices in the load control system.

Abstract: A system may include a plurality of master lighting modules and a fixture controller. The fixture control may include a power converter circuit that is configured to generate a bus voltage on a power bus. The plurality of master lighting modules may be serially-coupled on the power bus. The fixture controller may include a control circuit that is configured to receive an indication of a magnitude of an end bus voltage at an end master lighting module. The end master lighting module may be the master lighting module that is located furthest from the fixture controller along the power bus. The control circuit may be configured to generate a target bus voltage control signal based on the magnitude of the end bus voltage. The power converter circuit may be configured to control a magnitude of the bus voltage based on the target bus voltage control signal.

Abstract: The lighting device may be configured to perform black body curve fading. For example, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting load is adjusted (e.g., faded) along a black body curve. The control circuit may be configured to determine whether to fade from an initial color to a destination color in a Correlated Color Temperature (CCT) chromaticity space or an XY chromaticity space. The control circuit may be configured to determine whether the initial color and/or the destination color are on the black body curve. When the initial color and the destination color are determined to be on the black body curve, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting device is adjusted from the initial color to the destination color along the black body curve.
