Title:
WAVELENGTH CONVERSION DEVICE, LIGHT SOURCE SYSTEM AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/188460
Kind Code:
A1
Abstract:
A wavelength conversion device, a light source system and a projection system. The wavelength conversion device comprises a wavelength conversion element (1) which itself comprises a reflection layer (12), said reflection layer (12) comprising a first surface (120) and an opposite second surface (121). A light-reflecting layer (11) is positioned on the first surface (120). A first heat-dissipation film (13) is affixed to the second surface (121). The first heat-dissipation film (13) is a graphite heat-dissipation film. The present wavelength conversion device is characterized by high reflectivity and high thermal stability and is capable of maintaining highly efficient stability of light output in high-power light emission conditions.
