Title:
TRANSMISSION TYPE WAVELENGTH CONVERSION DEVICE AND LIGHT-EMITTING DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/052616
Kind Code:
A1
Abstract:
The present invention claims a transmission type wavelength conversion device and a light-emitting device using same. The transmission type wavelength conversion device comprises, stacked in sequence: a light-emitting glass layer, a transparent glass layer, a dielectric film and a transparent substrate. The light-emitting glass layer comprises a wavelength conversion material which converts excitation light into stimulated light; the dielectric film is plated on a surface of the transparent substrate, and the dielectric film transmits the excitation light and reflects the stimulated light; the transparent glass layer is disposed between the dielectric film and the light-emitting glass layer. The transmission type wavelength conversion device has the characteristics of simple structure and high reliability of the overall device.
