Document Type and Number:
WIPO Patent Application WO/2020/042318
Kind Code:
A1
Abstract:
A light-emitting device (1) for retinal cell repair and regeneration, which comprises a base (11) and an excitation light source (12), wherein the excitation light source (12) is arranged on the base (11), and comprises an LED chip (121) and a fluorescent powder layer (122), wherein the LED chip (121) is fixedly arranged on the base; the fluorescent powder layer (122) comprises a silica gel layer (1221), fluorescent powder (1222) is dispersed in the silica gel layer (1221), and the fluorescent powder layer (122) is fixedly arranged on the end surface of the LED chip (121) facing away from the base. The emission wavelength of the LED chip (121) is 200-520 nm, and under the excitation of the LED chip, the emission wavelength of the fluorescent powder is 570-850 nm.
