Title:
LIGHT SOURCE DEVICE AND LIGHT PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/044374
Kind Code:
A1
Abstract:
Provided are a light source device with which it is possible to effectively enhance the light emission intensity of a scan region as a whole without causing a decrease in the light emission efficiency, and a light projection device in which the light source device is used. The light source device is provided with laser light sources, a wavelength conversion member for converting the wavelength of laser lights emitted from the laser light sources to another wavelength and causing the laser lights to diffuse, an optical deflector for scanning the laser lights emitted from the laser light sources on an incidence surface of the wavelength conversion member, and a cylindrical lens and a cylindrical mirror for causing the laser lights emitted from the laser light sources to converge on the incidence surface of the wavelength conversion member in a beam shape that is long in a direction intersecting the scan direction. The laser light sources and an optical system are adjusted so that the laser lights emitted from the laser light sources are aligned in the scanning direction on the incidence surface of the wavelength conversion member and are separated from each other.
