US 5,998,925  Claims
What is claimed is:
1. A light emitting device, comprising a light emitting component and a phosphor capable of absorbing a part of light emitted by the light emitting component and emitting light of wavelength different from that of the absorbed light; wherein said light emitting component comprises a nitride compound semiconductor represented by the formula: Ini Gaj Alk N where 0≦i, 0≦j, 0≦k and i+j+k=1 and said phosphor contains a garnet fluorescent material comprising 1) at least one element selected from the group consisting of Y, Lu, Se, La, Gd and Sm, and 2) at least one element selected from the group consisting of Al, Ga and In, and being activated with cerium.
2. A light emitting device according to claim 1, wherein the phosphor used contains an yttrium-aluminum-garnet fluorescent material containing Y and Al.

US 7,531,960 CLAIMS
1. A light emitting device which comprises;
a light emitting component having a gallium nitride based semiconductor; and
a resin containing at least one phosphor capable of absorbing a part of a first light of blue color emitting from the light emitting component and emitting a second light of wavelength different from that of the absorbed first light, said emission of the second light emitted from at least one fluorescent material and a light of an unabsorbed first light passes through said fluorescent material from said light emitting component, said unabsorbed first light and said second light are capable of overlapping each other to make white light;
wherein a concentration of the phosphor increases from the surface of a resin that contains the phosphor toward the light emitting component, or the concentration of phosphor increases from the light emitting component toward the resin surface.
