Title:
WAVELENGTH CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/136830
Kind Code:
A1
Abstract:
Provided is a wavelength conversion apparatus, comprising: a metal substrate; and a light-emitting ceramic layer, wherein the light-emitting ceramic layer is used for absorbing excitation light and emitting excited light with a wavelength different from that of the excitation light, wherein a metal reflective layer and a silica gel layer are stacked between the metal substrate and the light-emitting ceramic layer, and the reflective layer is used for reflecting the excited light and an unconverted part of the excitation light. The wavelength conversion apparatus can reduce heat generated in the wavelength conversion apparatus, while realizing the aim of emitting excited light with a high illumination intensity in the wavelength conversion apparatus.
