Title:
HIGH TEMPERATURE RESISTANT REFLECTIVE LAYER FOR WAVELENGTH CONVERSION DEVICES
Document Type and Number:
WIPO Patent Application WO/2020/211824
Kind Code:
A1
Abstract:
A wavelength conversion device (100), such as a phosphor wheel, comprises: a substrate (110), a reflective layer(120) and a wavelength conversion layer(130) on the reflective layer(120). The reflective layer (120) comprises (A) an inorganic binder or an organic silicone, and (B) reflective nanoparticles(122). The nanoparticles(122) have a particle size of about 200 nanometers to about 500 nanometers. The reflective layer(120) has high thermal stability. A method of manufacturing the wavelength conversion device (100) and a light projection system comprising the wavelength conversion device(100) are also disclosed.
