Title:
WAVELENGTH CONVERSION APPARATUS AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/037317
Kind Code:
A1
Abstract:
The present invention relates to a wavelength conversion apparatus and a manufacturing method therefor. The wavelength conversion apparatus comprises a light-emitting layer, a reflective film, a sintered silver layer, and a substrate. The light-emitting layer converts a laser light into emitted lights of different wavelengths. The reflective film is plated on the light-emitting layer and used for reflecting the emitted lights emitted by the light-emitting layer. The sintered silver layer is connected to the light-emitting layer and the substrate; the sintered silver layer comprises sheet-shaped silver particles connected with each other via surface contact; and the sintered silver layer is formed by sintering spherical silver nanoparticles and sheet-shaped silver particles. The wavelength conversion apparatus is characterized by excellent thermal conductivity and high luminous efficiency.
