Patent ID: 7938550

Claim:
A light emitting device comprising: first and second LED chips having first and second light emitting portions for emitting light with first and second wavelengths which are different from each other; a base member having a concave portion for housing the first and second LED chips therein; and a translucent sealing resin having a flat surface and sealing the first and second LED chips housed in the concave portion, wherein the sealing resin contains a fluorescent material which is excited by the light with the first wavelength but is not excited by the light with the second wavelength, so that the light with the second wavelength and white light resulted from the mixture of the light with the first and second wavelengths and light emitted from the fluorescent material can be selectively emitted, the concave portion having an inner flat bottom surface mounting the first and second LED chips thereon, the second LED chip being taller than the first LED chip so that an optical path length from the second light emitting portion to the surface of the sealing resin is shorter than that from the first light emitting portion to the surface of the sealing resin.
