Abstract:
1. A light emitting apparatus comprising: a radiation source for emitting multi-colored radiation; a diffuser material coupled to a down conversion material for receiving at least a portion of the multi-colored radiation emitted by the radiation source and converting the multi-colored radiation into forward transferred radiation and back transferred radiation; and an optic device having a first end proximal the radiation source and a second end distal the radiation source, the proximal end of the optic device having a width smaller that a width of the distal end, the optic device disposed between (i) the radiation source and (ii) the diffuser material and the down conversion material, having at least one substantially transparent side wall absent the down conversion material, coupled to the diffuser material and the down conversion material, the optic device adapted to receive the back transferred radiation and extract at least a portion of the back transferred radiation from the optic device through the at least one substantially transparent side wall.
