Optics system for solid state lighting apparatus
First Claim
1. An optical element for transmission of light produced by a solid state emitter, comprising:
- at least one diffuser element; and
a reflector supported by the at least one diffuser element and spaced-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 annular lip having a planar inner rim, the reflector comprising;
a first frustoconical surface coupled with the planar inner rim of the annular lip, the first frustoconical surface extending outwardly from the annular lip in a first direction and at a first angle relative to the axis;
a second frustoconical surface coupled to the first frustoconical surface and extending outwardly at a second angle relative to the first frustoconical surface in a second direction; and
a third frustoconical surface coupled with the second frustoconical surface and extending outwardly at a third angle relative to the second frustoconical surface, wherein the third frustoconical surface is disposed substantially horizontally relative to the axis and a surface of the third frustoconical surface is on a same horizontal plane with a surface of the annular lip.

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.
