<P>PROBLEM TO BE SOLVED: To provide a light emitting device in which light emitted from a light emitting element can be highly efficiently converted into light of longer wavelength owing to employment of plural fluorescent materials each having a mutually different emitting light wavelength. <P>SOLUTION: Fluorescent material-contained resin 5 fills up the inside of a containing portion 4A in the light emitting device in such a way that the resin 5 covers the light emitting element 2 and a spacer 3. In a region where output of light emitted from the light emitting element 2 is high, a volume of a first fluorescent material section 5A containing a blue light fluorescent material is large. In a region where output of light emitted from the light emitting element 2 is low, a volume of a second fluorescent material section 5B containing a green light fluorescent material and a red light fluorescent material is large. <P>COPYRIGHT: (C)2008,JPO&INPIT |
