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.
Claims20
A modular lighting system comprising:
- a bridge module;
- an array of LEDs;
- a driver module providing a communication port and adapted to:
- drive the array of LEDs in response to information received from the bridge module;
- and
- provide power via a power port to the bridge module, wherein the bridge module is adapted to communicate with the driver module over a communication bus using a first protocol and communicate with a remote control system using a second protocol, which is different from the first protocol, wherein the driver module comprises rectifying circuitry and conversion circuitry adapted to convert an AC input signal into a DC power signal that is used to supply the power to the power port;
- and
- at least one auxiliary module, which is adapted to communicate with the driver module and the bridge module via the communication bus, wherein the at least one auxiliary module provides information used to determine how the driver module should control the array of LEDs.
