Title:
WAVELENGTH CONVERSION DEVICE AND LIGHT SOURCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/088160
Kind Code:
A1
Abstract:
A wavelength conversion device (100, 200, 300) and a light source system (400). The wavelength conversion device (100, 200, 300) comprises: a substrate (110, 210, 310); a reflective layer (120) disposed on the substrate (110, 210, 310); a heat conduction layer (130) stacked at a side of the reflective layer (120) away from the substrate (110, 210, 310); a wavelength conversion layer (140, 240, 340) stacked at a side of the heat conduction layer (130) away from the reflective layer (120), and used to receive an excitation light and emit an excited light; and an adhesive layer (150, 350) disposed around peripheral walls of the reflective layer (120) and the heat conduction layer (130), located below the wavelength conversion layer (140, 240, 340), and used to bond the wavelength conversion layer (140, 240, 340) and the substrate (110, 210, 310) together. The invention improves the performance of the wavelength conversion device (100, 200, 300) and extends the service life thereof.
