Referring to fig. 1 and fig. 2, the present embodiment provides a vehicle lighting module 100, which includes a bracket 110 and an optical element 120, wherein the optical element 120 is disposed inside the bracket 110, the optical element 120 includes an incident portion 125, a light-passing portion 124 and a light-emitting portion 123, light enters from the incident portion 125 and is transmitted in the light-passing portion 124, a portion of light is transmitted to the light-emitting portion 123 and is emitted through the light-emitting portion 123 to form a lighting shape, and another portion of light is transmitted to a side surface of the light-passing portion 124 and is emitted through a side surface of the light-passing portion 124 to form stray light 131; the bracket 110 is provided with a light-transmitting hole 111 for emitting stray light 131.
The vehicle lighting module 100 comprises a bracket 110 and an optical element 120, wherein the optical element 120 is used for collecting, conducting and converging light rays emitted by a light source and projecting the light rays out to form a required lighting light shape; the support 110 is disposed outside the optical element 120, and on one hand, the support plays a role in supporting and protecting the optical element 120, and on the other hand, the support can also block stray light emitted from the optical element 120. The stray light emitted from the optical element 120 is excessively irradiated on the support 110, if the energy of the light is concentrated, the local temperature of the support 110 is excessively high, and meanwhile, the support 110 also conducts heat to the optical element 120, so that the temperature of the optical element 120 is also increased, and the working performance and the service life of the optical element 120 are affected. Through arranging the light through hole 111 at a high-temperature position of the bracket 110, namely, a position where the irradiation energy of the stray light 131 is concentrated, the stray light 131 penetrates through the light through hole 111 to be emitted and is not absorbed by the bracket 110, so that the temperature of the bracket 110 and the optical element 120 can be prevented from being too high, the requirement on the heat resistance of the materials of the bracket 110 and the optical element 120 is reduced, the working performance of the bracket 110 and the optical element 120 is ensured, and the service life of the bracket 110 and the optical element 120 is prolonged.
It should be understood that the high temperature position of the bracket 110 refers to a position where the temperature is significantly increased after the stray light 131 with concentrated energy emitted from the optical element 120 is irradiated, and the stray light 131 with concentrated energy emitted from the optical element 120 directly irradiates the high temperature position, which may affect the working performance and the service life of the bracket 110 and the optical element 120. The hot position of the support 110 and the number, area and shape of the hot positions are influenced by the angle of the light emitted from the light source and the structure of the optical element 120.
In summary, in the vehicle lighting module 100 provided in this embodiment, the light-passing hole 111 is disposed at the high-temperature position of the bracket 110, so that the stray light 131 with concentrated energy emitted from the optical element 120 cannot irradiate on the bracket 110, thereby preventing the temperature of the bracket 110 and the optical element 120 from being too high, reducing the requirement on the heat resistance of the materials of the bracket 110 and the optical element 120, ensuring the working performance of the bracket 110 and the optical element 120, and prolonging the service life of the bracket 110 and the optical element 120.
Referring to fig. 3, optionally, in an implementation manner of the embodiment of the present invention, a light guide boss 121 is disposed on a surface of the optical element 120, the light guide boss 121 extends from the light through hole 111 to the support 110, the stray light 131 exits through the light guide boss 121, and the light energy is not absorbed by the support 110.
The light guide projection 121 and the optical element 120 may be made of the same material and located on the surface of the optical element 120, the light guide projection 121 is capable of transmitting light, and the stray light 131 with concentrated energy is emitted from the light guide projection 121 through the optical element 120. The light guide boss 121 extends out of the support 110 from the light through hole 111 of the support 110, and the stray light 131 is guided by the light guide boss 121 to exit more efficiently.
It should be understood that the light guide boss 121 may be adapted to the shape and size of the light through hole 111 on the bracket 110, so as to facilitate the positioning and matching of the optical element 120 and the bracket 110 when they are two parts separated from each other; the light guide boss 121 may also be smaller than the size of the light passing hole 111 as long as the light guide boss 121 can extend into the light passing hole 111.
Optionally, in an implementation manner of the embodiment of the present invention, the light guide bosses 121 and the light through holes 111 all include a plurality of light guide bosses 121 and a plurality of light through holes 111 in a one-to-one correspondence.
The light guide bosses 121 and the light through holes 111 have the same number and the positions thereof are in one-to-one correspondence, and are determined by the number and the positions of the high-temperature positions on the bracket 110. Illustratively, the number of the light guide bosses 121 and the light through holes 111 is four, four light guide bosses 121 are respectively located at four different positions on the surface of the optical element 120, two of the light guide bosses 121 are oppositely disposed, the other two light guide bosses 121 are oppositely disposed, the four light through holes 111 respectively correspond to the four light guide bosses 121, and the four light guide bosses 121 respectively extend into the corresponding light through holes 111.

The main function of the reflection groove 122 is to form a main dipped beam shape with a narrow upper and lower angle, so as to avoid the high illuminance near the vehicle, meet the requirements of relevant regulations and achieve good visibility in front of the vehicle. Due to the reflection groove 122, part of the light changes path and forms stray light 131, and the temperature of the bracket 110 is too high when the stray light irradiates on the bracket 110. The effective active surface of the reflective groove 122 that participates in reflecting light to become stray light 131 is the sidewall of the reflective groove 122. In a specific implementation process, in order to obtain a main low beam shape with a narrow upper and lower angles, the reflection groove 122 may be configured to have an arc shape, a triangular shape (in the form of a triangle in fig. 1) or a trapezoidal shape in a longitudinal section according to actual needs or process requirements.
Alternatively, in an implementation manner of the embodiment of the present invention, the reflection grooves 122 include two, and the two reflection grooves 122 are respectively located on two opposite surfaces of the optical element 120.

It should be understood that the bezel is used to block the stray light 131 emitted from the light-passing hole 111 of the bracket 110, but not to block the light emitted from the light-emitting portion 123 of the optical element 120 to form the illumination light shape.
Optionally, in an implementation manner of the embodiment of the present invention, the cross section of the light guide boss 121 is any one of a rectangle, a trapezoid, an arc and a triangle.
Specifically, the main function of the light guide projection 121 is to transmit the stray light 131 with concentrated energy, and in a specific implementation process, the cross section of the light guide projection 121 may be set to be rectangular, trapezoidal (in fig. 3, the example is a form of rectangular or trapezoidal), arc, triangular, or the like according to actual needs or process requirements.
