A light board structure includes a board body, a wireless transceiver module and a light-emitting member. The wireless transceiver module and the light-emitting member are both installed on the board body. The wireless transceiver module has a feeder wire and a ground wire. The board body has a collision avoidance area, which runs through the board body and disposed to avoid collision with the wireless transceiver module and the light-emitting member. The feeder wire and the ground wire are positioned on a side of the collision avoidance area. The collision avoidance area is configured to emit a radio wave, and solve a problem that the communication distance of a light board structure is short. A light fixture having the light board structure includes an installation cavity. The collision avoidance area of the light board structure matches an inner wall of the installation cavity to form a collision avoidance channel.

Light board structure and light fixture having the same

The apparatus includes a first transistor having a gate/base terminal to receive a first drive control signal used for controlling a driver stage of the transceiver and a drain/collector terminal coupled to a control terminal of a switch of the transceiver. The first transistor is switched on when the first drive control signal is at a first level that enables the driver stage to amplify a first RF signal. When the first transistor is switched on, the drain/collector terminal of the first transistor outputs to a control terminal of the switch a switch control signal at a second level that enables the switch to provide a portion of the RF signal reflected by the antenna to the load.
