A load control system for controlling at least one electrical load may comprise a plurality of control devices and a sensor external to at least one of the control devices. The sensor may be configured to sense a condition of a space in which the control devices are installed. The at least one electrical load may be controlled in response to the condition sensed by the sensor. The control devices may include respective illuminated portions. The control devices may adjust the intensity of the respective illuminated portions in response to the condition sensed by the sensor. If multiple sensors are included in the load control system to sense the condition, the control devices may adjust the intensity of their respective illuminated portions by aggregating the condition sensed by each sensor.

A synchronous control system is provided. A transmission device 1 includes a reception unit 11 that receives a control signal for a lighting device in a live event site and a transmission unit 13 that transmits, to a reception device in a live viewing site, the control signal to which an output time is appended. The output time is obtained by adding a predetermined period of time to a receipt time at which the control signal is received. A reception device 2 includes a reception unit 21 that receives the control signal to which the output time is appended, and an output control unit 13 that outputs the control signal to a lighting device 6 in the live viewing site at the output time, and allows the control of the lighting device 6 to synchronize with at least one of video and audio to be played in the live viewing site.

A linear lighting device may include an elongated housing that defines a cavity. The linear lighting device may include plurality of emitter printed circuit boards configured to be received within the cavity. Each of the plurality of emitter printed circuit boards may include a plurality of emitter modules mounted thereto. Each of the plurality of emitter printed circuit boards may include a control circuit configured to control the plurality of emitter modules mounted to the respective emitter printed circuit board based on receipt of one or more messages. The linear lighting device may include a total internal reflection lens for each of the plurality of emitter printed circuit boards. The total internal reflection lens may be configured to diffuse light emitted by the emitter modules of the plurality of emitter printed circuit boards.

A LED controller includes an image buffer to hold image data. An LED pixel forming a part of a large pixel array is activatable in response to image data, LDO state, and pulse width modulation module state. A logic module including a pixel diagnostic mode using an LDO bypass is connected to modify LDO state and allow direct addressing of the LED pixel for diagnostic purposes without needing to use image data from the image buffer.
