Document Type and Number:
WIPO Patent Application WO/2021/213195
Kind Code:
A1
Abstract:
Disclosed are a light-guiding element and a light source device. The light-guiding element comprises a first region and second regions respectively located on opposite sides of the first region, wherein the first region is used for reflecting at least some first light and transmitting second light; the second regions are used for transmitting the first light and the second light; and the wavelength range of the first light is different from the wavelength range of the second light. By means of the method, the present application can improve the light-emitting efficiency and reduce the cost.
