Title:
LIGHT SOURCE DEVICE, PROJECTION DISPLAY DEVICE, AND DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/170966
Kind Code:
A1
Abstract:
A light source device (10) of the present invention is provided with: a light source (11) that outputs light of a first wavelength range; an optical path dividing element (12) that divides the optical path of the light of the first wavelength range into first and second optical paths, said light of the first wavelength range having been outputted from the light source; a first fluorescent body (131a), which is disposed on the first optical path, excited by means of the light of the first wavelength range, and outputs light of a second wavelength range that is different from the first wavelength range; a second fluorescent body (131b), which is disposed on the second optical path, excited by means of the light of the first wavelength range, and outputs light of a third wavelength range that is different from the first and second wavelength ranges; and an optical path synthesizing element (12) that synthesizes the light of the second wavelength range, said light having been outputted from the first fluorescent body, and the light of the third wavelength range, said light having been outputted from the second fluorescent body.
