<P>PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting device that further reduces color unevenness, and prevents the degradation of efficiency in excitation of phosphor and in light extraction. <P>SOLUTION: The LED lamp 10 (semiconductor light-emitting device) has an LED chip 1, phosphor layers 5, 6 which are provided at least in two layers in a light emission direction (B2 direction) side of the LED chip 1 and include a phosphor which converts a wavelength of light emitted from the LED chip 1 and an Al-based thin film-like light diffusion part 7 disposed to be held between the phosphor layers 5, 6. <P>COPYRIGHT: (C)2010,JPO&INPIT |
