Patent ID: 8031393

Claim:
A light emitting apparatus comprising: an optic device having a top surface, a bottom surface, and at least one substantially transparent sidewall extending between the top surface and the bottom surface; a radiation source for emitting short wavelength radiation, the radiation source disposed adjacent the bottom surface of the optic device; a down conversion material, disposed on the top surface of the optic device and extending from the at least one transparent sidewall, receiving and down converting at least some of the short wavelength radiation emitted by the radiation source and back transferring a portion of the received and down converted radiation; the optic device disposed between the down conversion material and the radiation source and configured to pass radiation back-transferred from the down conversion material outside of the optic device through the at least one substantially transparent sidewall; a first reflective surface at least partially surrounding the optic device for reflecting at least some of the radiation extracted from the optic device through the at least one substantially transparent sidewall; and a second reflective surface at least partially surrounding the radiation source for reflecting at least some of the radiation emitted by the radiation source toward the down conversion material, an end of the second reflective surface extending from a bottom of the first reflective surface.
