Abstract
Provided is a method including determining a first incident angle at which light from a light source will impinge on a first thin-film reflective stack of a planned first reflector for a lighting system. The method also includes determining a second incident angle at which light from the light source will impinge on a second thin-film reflective stack of a planned second reflector for the lighting system. The method further includes designing, using a processor executing a software package, the first reflector, comprising tuning a reflective characteristic of the first thin-film reflective stack as a function of the first incident angle determined, and designing, using the processor executing the software package, the second reflector, comprising tuning a reflective characteristic of the second thin-film reflective stack as a function of the second incident angle determined.
