Abstract

A lighting fixture includes a solid-state light source, a fixture common bus, a driver module, and a control module. The fixture common bus is configured to receive at least one functional module and provide an input signal from the at least one functional module to one or more other modules. The driver module is coupled to the fixture common bus and the solid-state light source, and is configured to receive a power supply signal and provide a drive signal to the solid-state light source based on a driver control signal. The control module is coupled to the fixture common bus and configured to provide the driver control signal via the fixture common bus based on the input signal from the at least one functional module.
