Color mixing optics for a multi-color LED lamp comprise an outer reflector having a paraboloidal surface of revolution and a TIR (total inner reflection) 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. |
