A light fixture controller is configured for controlling the color temperature and intensity of a light fixture that includes at least two LED groups. Each LED group includes multiple LEDs configured to produce light at certain color temperatures. The light fixture controller receives a color temperature setting and an intensity setting for the light fixture and generates control signals based on these settings. A first control signal only turns on the first LED group for a first duration of a cycle and a second control signal only turns on the second LED group for a second duration of the cycle. The ratio between the first and second duration is determined based on the color temperature setting. The control signal further includes a dimming control signal for controlling a current flowing through the LED groups based on the intensity setting for the light fixture.

Lighting fixture controller for controlling color temperature and intensity

An auxiliary power system for powering an auxiliary circuit is connected to the same power source that powers the lighting element within a luminaire. The auxiliary power system may be connected to the output of the power source in series or in parallel with the lighting element. The power source may be an LED driver and the lighting element may include one or more LEDs or the power source may be an electronic ballast and the lighting element may be one or more fluorescent lamps.
