LIGHT SOURCE DEVICE AND PROJECTION-TYPE DISPLAY DEVICE

摘要

The present invention is provided with: a laser light source; a circular substrate (6) having a fluorescent body (5) that emits light, with light from the laser light source being the excitation light; a wheel motor (7) for causing the circular substrate (6) to rotate; a dichroic prism that reflects light from the laser light source and transmits light from the fluorescent body (5); a diffusion plate (19a) for diffusing light from the laser light source; and a plate spring (20a) for connecting the diffusion plate (19a) and the wheel motor (7).
