<P>PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element capable of emitting light having a plurality of wavelengths without increasing its size. <P>SOLUTION: A light emitter 30 is provided on a transparent wavelength conversion substrate 12 to an emission wavelength, and light generated by the emitter 30 is emitted from the side of the wavelength conversion substrate 12. The wavelength conversion substrate 12 has a plurality of projecting wavelength converters 11 on a substrate 10 (a sapphire substrate). For the wavelength converters 11, a conversion particle 14 is dispersed which is composed by containing, for example one or a plurality of rare earth elements inside a medium 13 made of, for example SiO<SB>2</SB>(silicon oxide). Light entering the wavelength converter 11 in emission light from an emission region 19A is wavelength-converted by the conversion particle 14 inside the wavelength converter 11, and is emitted from the side of the substrate 10. As a result, the light having a plurality of wavelengths is emitted from the semiconductor light-emitting element. <P>COPYRIGHT: (C)2007,JPO&INPIT |
