Title:
LIGHT SOURCE DEVICE AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/002254
Kind Code:
A1
Abstract:
Disclosed is a light source device which can be built into a 3CCD projection-type display device and which uses fluorescent bodies as a light source and can extend the life span of the fluorescent bodies. The disclosed light source device is provided with: a semiconductor laser (1); a reflective fluorescent body assembly (42) which receives excitation light emitted from the semiconductor laser (1) and emits prescribed coloured light; a dichroic mirror (24) which reflects one of either the incoming excitation light and the incoming fluorescence and allows the other to permeate; a heat radiation unit (9) which radiates the heat generated by the reflective fluorescent body assembly; movement mechanisms (12, 14) which move the reflective fluorescent body assembly in the direction parallel to the surface of said reflective fluorescent body assembly; and an afocal optical system comprising at least one negative optical element (5) and at least one positive optical element (6) for changing the size of the luminous flux of the fluorescence from the reflective fluorescent body assembly.
