Single-layer printed circuit board for a lighting device

A lighting device assembly comprising:

• a printed circuit board assembly comprising:
• a metal-core printed circuit board comprising a base layer, a single electrical layout layer, and a single dielectric layer located between the base layer and the electrical layout layer, the electrical layout layer comprising a plurality of electrical pads, a plurality of electrical traces, and a ground plane;
• an emitter assembly comprising a plurality of emitters configured to emit light, the plurality of emitters mounted to the printed circuit board and electrically connected to two or more of the plurality of electrical pads;
• drive circuitry configured to control power delivered to the plurality of emitters of the emitter assembly, the drive circuitry mounted to the printed circuit board and electrically connected to the two or more of the plurality of electrical pads;
• and
• communication circuitry configured to transmit and receive wireless signals, the communication circuitry configured to cause the drive circuitry to control the emitters in response to messages received via the wireless signals, the communication circuitry mounted to the printed circuit board and electrically connected to the two or more of the plurality of electrical pads, the communication circuitry comprising a circuit common electrically coupled to the ground plane of the printed circuit board;
• and
• a reflector that has a first opening, a second opening, and an inner surface that is reflective, the plurality of emitters configured to emit light through the first opening of the reflector, the inner surface of the reflector configured to reflect the light through the second opening of the reflector;
• wherein the printed circuit board assembly further comprises an antenna coupled in electrical communication with the communication circuitry for allowing the communication circuitry to communicate messages via the wireless signals that are transmitted and received by the antenna, the antenna extending from the printed circuit board external to the reflector.
