Abstract:
1. A light emitting apparatus comprising: a radiation source for emitting short wavelength radiation; an optic device having a top surface distal the radiation source, a bottom surface proximal the radiation source, the proximal end of the optic device having a width smaller that a width of the distal end, and at least one substantially transparent sidewall extending between the top surface and the bottom surface; 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 adjacent the down conversion material and at least partially surrounding the radiation source, the optic device configured to i) receive at least a portion of the radiation back transferred from the down conversion material and ii) transfer at least some of the received portion of back-transferred radiation outside the optic device through the at least one substantially transparent sidewall; and at least one sealant for substantially sealing a space between the radiation source and the optic device.
