Title:
COLOR WHEEL ASSEMBLY, LIGHT SOURCE APPARATUS, AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/134261
Kind Code:
A1
Abstract:
A color wheel assembly, comprising: a bearing component 161; a wavelength conversion component 165 surrounding and fixed to the circumferential wall of the bearing component 161, and used for receiving the excitation light of an excitation light source 120 and for generating excited light; a light filtering component 167 fixed to one end surface of the bearing component 161 and surrounding and extending along the circumferential direction of the bearing component 161, and used for receiving and filtering said excited light. A light source apparatus, comprising: the excitation light source 120 used for generating excitation light; and a color wheel assembly 160, wherein the wavelength conversion component 165 is arranged to be in the transmission path of the excitation light and sequentially outputs excited light and excitation light when irradiated by the excitation light source 120. A projection system, comprising a light source apparatus 100.
