Abstract

The present disclosure relates to a modular lighting system that may include a driver module, an array of LEDs that are driven by the driver module, and one or more auxiliary modules. The auxiliary modules are configured to control the driver module, which in turn drives the LEDs of the array of LEDs in a desired fashion. The auxiliary module may provide a bridge for communications with one or more remote lighting control systems through wired or wireless communications and function to control the driver module accordingly. Other exemplary auxiliary modules may include modules that function to control the driver module based on one or more of ambient light, ambient temperature, room occupancy, emergency lighting requirements, and the like.
