Abstract:
A light emitting device, comprising:a base member; a reflecting surface formed on the base member; a transparent resin provided on the reflecting surface and containing a wavelength converting material therein; and a transparent semiconductor luminous element provided on the transparent resin and having a lower surface and an upper surface for emitting light, said semiconductor luminous element emitting the light upwardly without wavelength conversion, and downwardly to convert by the wavelength converting material a wavelength of the light emitted from the lower surface of the semiconductor luminous element, one part of the light emitted downwardly being converted by the wavelength converting material to orient upwardly and the other part of the light emitted downwardly and converted being reflected on the reflecting surface to orient upwardly, the one and the other parts of the light converted by the wavelength converting material and oriented upwardly being mixed with the light directly emitted from the upper surface of the semiconductor luminous element to emit white light.
