Problems solved by technology

[0003] In order to produce visually recognizable optical signs, light-emitting devices are usually used to produce bright areas, and light-shielding elements are used to produce dark areas. However, sometimes the formation of dark areas is not ideal, especially when the marking part is combined with a light-emitting device of a motor vehicle. Light leakage may occur due to insufficient shading, resulting in unwanted light spots, or color errors due to uneven shading, which will lead to unclear optical marks and affect display quality

Abstract

The invention provides a light guiding element, a lighting module, a motor vehicle and a manufacturing method thereof. The light guiding element (100) comprises a light guiding body (1) and a metal plating layer (3), wherein the light guiding body (1) comprises a light incident portion (6), a main light guiding portion (7) and a light emergent portion (8), the light guiding element (100) further comprises at least one layer of light-shielding paint layer (2), and the light-shielding paint layer (2) is at least arranged on a light emergent surface (5) of the light emergent portion (8) of the light guiding body (1), the metal plating layer (3) is arranged on the light-shielding paint layer (2), the light-shielding paint layer (2) at least partially covers the light emergent surface (5) of the light emergent portion (8), and the uncovered light emergent surface (5) is used for forming an identification portion (4) on the light emergent portion (8). The light guiding element (100) is usedfor generating an optical identifier.

Description

technical field [0001] The present invention relates to the technical field of motor vehicles, in particular to a light guide element, an illumination module, a motor vehicle and a manufacturing method for the light guide element. Background technique [0002] For the sake of aesthetics and decoration, it is often desirable to provide specially designed logos on motor vehicles, and the usual logos include words, numbers, letters, characters, symbols, graphics and various design elements and the like. It would be advantageous if the logo can be illuminated, because it can enrich the styling design of the motor vehicle, improve the level of personalization, improve the quality of the motor vehicle, and expand brand recognition. [0003] In order to produce visually recognizable optical signs, light-emitting devices are usually used to produce bright areas, and light-shielding elements are used to produce dark areas. However, sometimes the formation of dark areas is not ideal, ...
