Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/217523
Kind Code:
A1
Abstract:
Disclosed is an electronic device (1000), comprising a device housing (100) and a light-emitting assembly (200) arranged in the device housing (100). A light outlet (1001) is provided in the device housing (100), and the light-emitting assembly (200) comprises a light source (10) and a light guide apparatus (20); the light guide apparatus (20) comprises a light guide column (21), and the light guide column (21) comprises a light incident face (201), a reflecting face (202) and a light emergent face (203); the light incident face (201) is located on one side of the light guide column (21) and directly faces the light source (10); the light emergent face (203) is located on the other adjacent side of the light guide column (21) and directly faces the light outlet (1001); and the reflecting face (202) is obliquely opposite the light incident face (201) and the light emergent face (203), and the reflecting face (202) is an arc-shaped convex face and is formed from a recess of the light guide column (21). Light emitted by the light source (10) enters the light guide column (21) from the light incident face (201), is redirected after being reflected by the reflecting face (202), leaves the light guide column (21) from the light emergent face (203), and emerges from the light outlet (1001). By configuring the reflecting face (202) in the form of an arc-shaped convex face, the design requirement of a light emergent angle lateral to the irradiation direction of the light source (10) can be realized in a relatively small space, and a large external indication light-emergent area and a good light emergent effect are achieved.
