Title:
WAVELENGTH CONVERSION DEVICE AND LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2019/010910
Kind Code:
A1
Abstract:
Disclosed are a wavelength conversion device (100) and a preparation method therefor, and a light source. The wavelength conversion device (100) comprises a light-emitting layer (101), a glass bonding layer (102), a silver reflective layer (103), a setter substrate (104), a silver bonding layer (105), a welding layer (106) and a heat conducting substrate (107) being successively superposed, wherein the light-emitting layer (101) is an inorganic light-emitting layer capable of absorbing light within a certain wavelength range and emitting light within a different wavelength range. The wavelength conversion device (100) has the characteristics of high reflectivity, low thermal resistance and high long-term reliability.
