US Patent 11777199 Modular wireless modules for light fixtures

A light fixture includes a housing containing a light engine, and a wireless baffle module. The wireless baffle module includes a baffle coupled to the housing and used for focusing light emitted from the light engine. The wireless baffle module further includes a wireless printed circuit board assembly coupled to an antenna. The wireless printed circuit board assembly receives and processes wireless signals from the antenna, and sends control signals to the light engine based on the wireless signals. The wireless baffle module may be coupled to a lighting system with an existing non-wireless module, or be used to replace a wireless baffle module with the same or different wireless protocol.
