Abstract:
Systems and methods for driving solid state light sources are provided. A first drive circuit is configured to generate a drive current to cause a first solid state light source load and a second solid state light source load to illuminate. A feedback and control circuit is configured to receive feedback from the first solid state light source load and to control the drive current through the first solid state light source load based on the feedback. A second drive circuit is configured to control the drive current through the second solid state light source load. A master controller is configured to provide a first input to the feedback and control circuit to control the drive current through the first solid state light source load and a second input to the second drive circuit to control the drive current through the second solid state light source load.
