Abstract:
A lighting device may include a light source, a plurality of drive circuits, and a control circuit. The light source may include a plurality of emitter circuits that are configured to emit light. The light source may include a first emitter circuit that is configured to emit light at a first color (e.g., color temperature), a second emitter circuit is configured to emit light at a second color (e.g., color temperature), and a third emitter circuit is configured to emit light at a third color (e.g., color temperature). The first, second, and third colors (e.g., color temperatures) may be on a color curve, such as a color temperature curve like the black body locus. The control circuit may be configured to control the amount of power delivered to no more than two emitter circuits to emit light when controlling the light emitted by the light source to the target intensity.
