Abstract:

An optical element for transmission of light produced by a solid state emitter includes at least one diffuser element, and a reflector supported by the at least one diffuser element and paced-apart from the emitter, the reflector defining an annular lip having an aperture therein and an axis normal to a plane defined by the aperture. The reflector further includes a first frustoconical surface coupled with the annular lip and angling outwardly in a first direction at a first angle relative to the axis, a second frustoconical surface coupled to the first frustoconical surface and angled outwardly at a second angle in a second direction opposite to the first direction, and a third surface coupled with the second frustoconical surface and angling outwardly at a third angle.
