Patent ID: 7857485

Claim:
A light emitting apparatus, at least comprising: a light emitting device; a conducting wire structure; an encapsulating body, wherein the light emitting device is positioned inside the encapsulating body, electrically coupled with the conducting wire structure, and thus emits a light at a first frequency range under a suitable driving voltage; a first dielectric layer, covering a light emitting surface of the light emitting device and highly transmitting the light at the first frequency range, wherein the light emitting device includes a semiconductor layer having a first index of refraction, the encapsulating body has a second index of refraction higher than the first index of refraction, and the first dielectric layer has a third index of refraction that bridges a difference between the first index and the second index of refraction; a packaging material, filling into the encapsulating body, wherein the packaging material at least comprises one luminescent material, which can be excited by the first frequency range light to generate at least a second frequency range light; and a reflector, disposed on a light emitting surface of the encapsulating body, reflecting the first frequency range light back to the encapsulating body omni-directionally, wherein the excited second frequency range light can pass through the reflector, and the first frequency range light excites the luminescent material inside of the encapsulating body, thus resulting in light emission at least at a first, and a second frequency, or a single light emission at a second frequency range from the apparatus.
