Abstract
An optical emitter enabling conversion of light from a light source. The optical emitter includes a first conic reflector defining an aperture for receiving the light source, a second conic reflector opposite the first conic reflector for collimating light emitted by the light source, and a volumetric light conversion element between at least a portion of the first reflector and at least a portion of the second reflector. The optical emitter can also include a convex mirror adjacent the vertex of the second conic reflector, and an elliptical element adjacent the first conic reflector. The light conversion element can include phosphor dispersed in a resin to convert light from a first wavelength to light of a second, longer, wavelength, wherein converted light is emitted from the light conversion element.
