Abstract
A light emitting device effectively utilizes the light emanating from a semiconductor luminous element, and can acquire clear and high-luminance light emission without a color dapple. The light emitting device is configured as follows. A transparent resin containing a wavelength converting material is provided on a reflecting surface of a base member such as a case, a board and a lead frame. The transparent semiconductor luminous element is bonded and fixed on the transparent resin. A wavelength of light emitted from a lower surface of the semiconductor luminous element is converted by the wavelength converting material, and the converted light is reflected on the reflecting surface. The reflected light is mixed with light emitted from an upper surface of the semiconductor luminous element, and the mixed light is radiated.
