Title:
LASER LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/068471
Kind Code:
A1
Abstract:
A laser light source device, comprising: a light source exciter (10), an optical path integrating unit (20), a first color wheel (50) having a light transmitting area (51) and a fluorescent area (52), a second color wheel (60) having two kinds of color light filtering areas (61, 62) alternately arranged, an optical path guiding unit (30) for guiding the light source exciter, a relay lens group (43, 44), a group of collimators (41, 42), mirrors (23, 45) and a light source reception unit (46). The device reduces the consumption of the light source using the optical path guiding unit (30), and improves luminance, thereby improving the quality of pictures, and at the same time, the structure makes the color wheels easier to implement.
