Patent ID: 8403538

Claim:
An optical assembly comprising: a light source having an optical axis and configured to emit light, where a color of the light varies based on a direction the light is emitted from the light source; an optical element positioned transverse to the optical axis and configured to mix the light, the optical element including a unitary body that has a collimating lens and a plurality of deflecting lenses disposed on opposite sides of the unitary body, wherein the color of the light mixed by the optical element is independent of a direction at which the light emanates from the optical element; a reflector defining an interior chamber in which the light source is disposed, the reflector configured to reflect at least a first portion of the light generated by the light source toward the optical element, wherein the interior chamber is filled with a light transmissive material that is separate from the optical element and having an equivalent index of refraction as the collimating lens; and a mask disposed between the deflective lenses of the optical element, the mask configured to reflect at least a second portion of the light that is emitted from the light source back toward the light source and the reflector.
