摘要:
A solid-state light source device, enabling to build up with using solid-state elements, and having the structure suitable to be applied as a light source for a projection-type display apparatus, comprises a solid-state light source unit 10 for emitting excitation light therefrom, a reflection mirror (or reflector) 130 made of a parabolic surface, for condensing the excitation light from the solid-state light source to be point-like, and a disc-like (or wheel) member 140, repeating reflection/scattering or transmission/scattering of the excitation light and conversion of the excitation light, alternately, in vicinity of a focus point of the excitation light, which is condensed to be point-like by the reflection mirror (or reflector), wherein the excitation light (B-color) reflected/or scattered by that disc-like (or wheel) member and fluorescence light (Y-color), wavelength of which is converted, is taken on a same optical path, by means of the reflection mirror (or reflector) 130 or a second reflection mirror (or reflector) 130′, and thereby outputting a white color light emitting from a point-like light source.
