<P>PROBLEM TO BE SOLVED: To obtain a uniform luminous color stably by avoiding fine variations in the luminous wavelength and intensity of a semiconductor light-emitting element chip itself for emitting ultraviolet rays or near ultraviolet rays and an influence by the difference of each deterioration speed of a phosphor emitting visible light. <P>SOLUTION: A fluorescent unit 2 for holding the same number of light transmitting fluorescent members 22a, 22b, 22c as that of the semiconductor light-emitting element chips having the phosphor emitting visible light in one frame member in a light source unit 1, where a plurality of semiconductor light-emitting element chips 12a, 12b, 12c are held adjacently on one substrate, is detachably mounted to the front in the emission direction of the semiconductor light-emitting element chip. The light-emitting fluorescent member is arranged so that it opposes each of the semiconductor light-emitting element chips one by one, is allowed to emit light by ultraviolet rays or near ultraviolet rays emitted from the opposing semiconductor light-emitting element chip, thus mixing visible light emitted from the light-emitting fluorescent member forward in the direction of emission. <P>COPYRIGHT: (C)2007,JPO&INPIT |
