摘要:
Disclosed are systems and methods for providing multi-channel illumination. A reflector and at least four solid state light sources are operable to emit light. A plurality of combinations of the solid state light sources are identified, where each of the combinations is operable to emit light that matches a target color point. The combinations are ranked based on their respective luminous flux value, and at least one of the combinations is selected based on the rank. A duty cycle of a control signal of each light source of the selected combinations is determined to control light emitted from the reflector.
