Title:
REFLECTION DEVICE, RELATED WAVELENGTH CONVERSION DEVICE, COLOR WHEEL, AND LIGHT SOURCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/181965
Kind Code:
A1
Abstract:
Provided are a reflection device, a related wavelength conversion device, a color wheel, and a light source system. The reflection device comprises a ceramic substrate (S3) and a diffuse reflection glass layer (S1) located at a first surface of the ceramic substrate (S3). The diffuse reflection glass layer (S1) comprises a second surface away from the ceramic substrate (S3). The ceramic substrate (S3) is a ceramic body having adense structure. With respect to the same single ray of light, a solid divergence angle of the light reflected by the first surface is less than a solid divergence angle of the light reflected by the second surface. The diffuse reflection glass layer (S1) has a thickness of 0.04mm-0.15mm. The reflection device solves a breakage problem of a diffuse reflection glass layer having a greater thickness without changing a diffuse reflection characteristic of the diffuse reflection glass layer.
