Patent ID: 7750362

Claim:
A semiconductor light-emitting device comprising: a hollow body including a bottom wall and a surrounding wall extending upwardly from a periphery of said bottom wall, said bottom wall being formed with a through-hole, said surrounding wall cooperating with said bottom wall to define an encapsulant-receiving recess in spatial communication with said through-hole, said surrounding wall having a diffuse surface that surrounds said encapsulant-receiving recess and that has a reflectivity composed of a diffuse reflectivity and a specular reflectivity, the diffuse reflectivity being larger than the specular reflectivity; a heat-dissipating body provided on a bottom side of said bottom wall and covering said through-hole in said bottom wall; a light-emitting chip disposed in said through-hole in said bottom wall for generating a light in said hollow body, and supported on said heat-dissipating body; a transparent encapsulant filling said encapsulant-receiving recess and said through-hole to enclose said light-emitting chip; and a wavelength-converting layer that is capable of converting the wavelength of the light into a desired wavelength and that covers said transparent encapsulant.
