Sunshade device and lighting module for vehicle including sunshade device

Abstract

The invention provides a shading device (3), which comprises a shading body part made of an opaque material for at least partially blocking light from a light source (1) (101), a plurality of air convection passages are provided on the light-shielding main body, and the air convection passages are configured such that light (101) from the light source (1) cannot propagate through the air convection passages. The present invention also provides a lighting module (100) for a vehicle including the shading device (3). The shading device of the present invention has sufficient anti-glare effect when used with the lighting module and is not easily damaged by the heat of the light source assembly.

Description

technical field [0001] The present invention relates to the technical field of lighting equipment, in particular to a shading device and a lighting module including the shading device for vehicles, especially the shading device and the lighting module used in motor vehicles. Background technique [0002] In the application of some lighting modules, a shading device or a shading assembly, also known as a lampshade, is required. The shading device controls the spread of light by inhibiting the light from irradiating in a specific direction or inhibiting the light from illuminating a specific area. In a lighting module of a motor vehicle, such as a headlight module, a shading device is provided in front of the light source assembly, so as to prevent the light emitted by the light source assembly from directly irradiating to the front and causing glare to pedestrians in front of the vehicle or drivers of other vehicles, so as to Make the light shine in the desired way.

AI Technical Summary

Problems solved by technology

[0003] In the lighting module of a motor vehicle, traditionally, the shading device, the light source assembly and the reflector are arranged sequentially. In order to achieve the anti-glare effect, the shading device needs to be covered on the light source assembly and arranged at a predetermined distance from the light source assembly. The design of the predetermined distance is difficult to design. If the predetermined distance is large, the anti-glare effect will be reduced, because the light emitted by the light source assembly may irradiate outside the reflective surface of the reflector or irradiate on other components, so that the On which uncontrolled diffuse reflections are produced, with the undesired result of blinding pedestrians or drivers of oncoming vehicles

However, if the predetermined distance is small, although the anti-glare effect can be ensured, the large amount of heat generated by the light source assembly will cause the shading device to be burnt or damaged, reducing the service life of the lighting module

[0004] In addition, in the prior art, arranging the shading device in front of the light source assembly requires a separate connecting structure or fixing element, so the number of parts is large, the installation is complicated, and the manufacturing and installation costs are high
