Title:
LIGHT SUPPLEMENTATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/107162
Kind Code:
A1
Abstract:
Disclosed is a light supplementation device (100), comprising a mounting plate (6) as well as a first lamp bank (1) and a second lamp bank (2) disposed thereon. Light emitted from a first light emitting element (11) of the first lamp bank (1) exits from a first light-exiting surface (122) of a first prism (12), the first prism (12) having a first prism angle. Light emitted from a second light emitting element (21) of the second lamp bank (2) exits from a second light-exiting surface (222) of a second prism (22), the second prism (22) having a second prism angle. The first prism angle is different from the second prism angle such that light from the first lamp bank (1) and light from the second lamp bank (2) exit to different directions so as to supplement light for different ranges (51) of an area subject to light supplementation (5), thereby avoiding nonuniform brightness caused by light supplementation in a single direction. The mounting plate (6) realizes the combination and assembly of lamp banks with different light exiting directions, avoiding the complexity of respectively installing a plurality of lamp banks.
