Color Mixing Optics for LED Lighting

摘要

Color mixing optics for a multi-color LED lamp comprise an outer reflector having a paraboloidal surface of revolution and a total inner reflection (TIR) lens having an outer contour with a paraboloidal surface of revolution. The outer reflector and the TIR lens are centered around a common center axis. A common focal point of the outer reflector and the TIR lens is provided for placing a LED assembly. Such LED lamps produce uniform color throughout the entire light beam while the outer dimensions are such that the optics fit into conventional lamp housings.

1. A color mixing optics for LED lighting comprising:
an outer reflector having a paraboloidal surface of revolution centered around a center axis and defining a reflector focal point; a total inner reflection (TIR) lens having an outer contour with a paraboloidal surface of revolution centered around the center axis and defining a TIR lens focal point; and wherein the reflector focal point is in close proximity to the TIR lens focal point.
