摘要：
Lighting systems comprising a spectrum former upstream from a reflectivepixelated spatial light modulator (reflective SLM), the SLM reflectingsubstantiallyall of the light in the spectrum into at least two different light paths, thatdo notreflect back to the light source or the spectrum former. At least one of thelightpaths acts as a projection light path and transmits desired light out of thelightingsystem. The lighting systems provide virtually any desired color(s) andintensity(s) of light, and avoid overheating problems by deflecting unwantedlightand other electromagnetic radiation out of the system or to a heat managementsystem. The systems can be part of another system, a luminaire, or any othersuitable light source. The systems can provide virtually any desired light,from thelight seen at the break of morning to specialized light for treating cancer orpsoriasis, and may change color and intensity at speeds that are perceptuallyinstantaneous.
