Document Type and Number:
WIPO Patent Application WO/2021/174892
Kind Code:
A1
Abstract:
Disclosed are a light guide assembly and a cosmetic mirror using the light guide assembly. The light guide assembly comprises a light guide plate (10), wherein the light guide plate (10) comprises a light-emitting part (20) and a light transfer part (30); the light-emitting part (20) is arranged in a ring shape; the light-emitting part (20) has an inner surface (21), and the light transfer part (30) is arranged on the inner surface (21); the light transfer part (30) has a light emergent face (31), an arc-shaped face (32), and a light incident face (33) that connects the light emergent face (31) and the arc-shaped face (32); the light emergent face (31) is configured to be attached to the inner surface (21); the distance between the arc-shaped face (32) and the light emergent face (31) gradually decreases in the direction away from the light incident face (33); and the light incident face (33) is located at one end of the light transfer part (30), and the light incident face (33) is obliquely arranged. The light transfer part (30) of the light guide assembly is configured to transfer light emitted by a light source (40) into the light-emitting part (20), the light-emitting part (20) is configured for scattering the light, and the oblique arrangement of the light incident face (33) facilitates extension of the path of propagation of light, achieves good light diffusion in the light-emitting part (20), and effectively weakens local bright spots in the light-emitting part (20), thereby effectively improving the uniformity of the light scattered by the light-emitting part (20).
