Linear lighting device

A lighting system comprising:

• a linear lighting device comprising:
• an elongated housing defining a cavity extending along a longitudinal axis of the housing;
• a plurality of printed circuit boards configured to be received within the cavity of the housing;
• and
• a plurality of emitter modules mounted to each of the plurality of printed circuit boards;
• wherein each of the plurality of emitter printed circuit boards has a control circuit mounted thereto, the control circuit configured to control the plurality of emitter modules mounted to the respective emitter circuit board based on receipt of one or more messages, and
• wherein each of the plurality of emitter printed circuit boards has a drive circuit mounted thereto, the drive circuit configured to:
• receive a DC bus voltage for powering the plurality of emitter printed circuit boards;
• and
• conduct drive currents through the plurality of emitter modules mounted to the respective printed circuit board;
• and
• a power supply configured to provide the DC bus voltage to the linear lighting device, the power supply comprising:
• a wireless communication circuit configured to transmit and receive messages;
• and
• a serial communication circuit configured to communicate one or more messages with the linear lighting device via a communication bus.
