Title:
WAVELENGTH CONVERSION APPARATUS, LIGHT-SHADOW PROCESSING DEVICE AND LIGHT PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/120716
Kind Code:
A1
Abstract:
A wavelength conversion apparatus, a light-shadow processing device and a light processing method, relating to the technical field of light-shadow processing. The wavelength conversion apparatus comprises: a base (100), a light-conducting device (200) and a drive device (300), the base (100) being provided with a light-conducting portion (110) and a wavelength conversion portion (120), and the drive device (300) being in transmission connection with the base (100), so that the light-conducting portion (110) and the wavelength conversion portion (120) are alternately located in a preset light path of the light-conducting device (200). The emission of blue light is implemented in the wavelength conversion apparatus, so that uniform and healthy blue light can be obtained, thereby facilitating the simplification of an optical path structure.
