Abstract

A light source device includes a laser light source for emitting a first light, a refractive optical element disposed on a light exiting path of the laser light source and configured to guide the first light to a light conversion device. The refractive optical element includes a light-exiting surface and light refracted by the light-exiting surface of the refractive optical element is deflected towards the light conversion device to exit. The light conversion device is disposed at a light-exiting side of the refractive optical element and the incident surface and light-exiting surface thereof are the same surface. The medium of the incident surface of the light conversion device has Brewster's angle of a and outgoing light of the refractive optical element is obliquely incident to the light conversion device at an incident angle of α−20° to α+10°. Also, the light collecting device is disposed at the light-exiting side of the light conversion device and configured to collect light emitted from the light conversion device and then emit it.
