HIGH-EFFICIENCY LIGHT- EMITTING APPARATUS USING LIGHT EMITTING DIODES
摘要
A light emitting apparatus having a light source for emitting short wavelength radiation and an optic device configured to receive the radiation emitted from the light source. A device directs at least some of the short wavelength radiation emitted from the light source into the optic device and a down conversion material receives at least some of the short wavelength radiation directed into the optic device in one spectral region and emits the radiation in another spectral region.
