Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting, in particular to a headlight optical module and a headlight using the same. Background Art

[0002] The rapid development of automotive lighting technology has put forward more requirements on the lighting technology of automotive lamps. The design elements of through-lights are beginning to be applied to more and more car models. In order to attract customers' attention, existing car lights are no longer just meeting the requirements of uniformity, but pursuing more personalized lighting effects.

[0003] For example, the starry sky lighting effect. For example, the existing technology for implementing this starry sky lighting effect has a method, for example, announcement number CN 221076234 U discloses a headlight module and a vehicle. The method for implementing this starry sky lighting is roughly as follows: black paint is sprayed on the back of a colorless transparent part or a dark transparent part, and then a pattern is laser engraved. A light source is placed behind it, and when it is lit, light is transmitted through the pattern to achieve a star-like effect. However, the effect is single and lacks a sense of layering. Moreover, when the transparent part sprayed with black paint is not lit, although there is a transparent exit hole, there is no light inside the product, and the light exit hole is still dark, making it difficult to see the pattern with the hole. The overall shape is dark without any shape effect.

[0004] Therefore, for the existing technology used to achieve the star-shaped lighting effect of the headlights, in order to further optimize the lighting effect, it is necessary to further optimize its structure. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0033] Example 1:

[0034] See also Figures 1 to 4 As shown, this embodiment provides a headlight optical module, including: a light-emitting element 4, a reflector 3, a second transparent element and a first transparent unit used in conjunction with each other.

[0035] Specifically, the first transparent unit used in this embodiment includes at least one first transparent member. The number of first transparent members used can be determined based on the size of the specific headlight. For smaller headlights, only one first transparent member may be used, while for larger headlights, two or even more first transparent members may be used. This embodiment does not impose an absolute limitation on this. The following description, combined with the accompanying drawings, uses the example of a single first transparent member.

[0036] The first transparent part includes a first light-transmitting portion 11 and a first mounting portion 12 for facilitating assembly of the first transparent part with other parts. The first light-transmitting portion 11 is made of a light-transmitting material, while the first mounting portion 12 is made of an opaque material. The first light-transmitting portion 11 and the first mounting portion 12 here can be optionally made by two-color injection molding.

[0037] In addition to the above structure, a plurality of first sequins 13 are attached to the light incident surface of the first light-transmitting portion 11 at intervals, and a plurality of second sequins 14 are attached to the light exiting surface of the first light-transmitting portion 11 at intervals. The first sequins 13 can be designed using processes such as, but not limited to, hot stamping, painting, aluminum plating, or chrome plating. Similarly, the second sequins 14 can be designed using processes such as, but not limited to, hot stamping, painting, aluminum plating, or chrome plating.

[0038] It should be noted that the structures of the first and second sequins 13, 14 can be identical or different. Furthermore, the multiple first sequins 13 on the light-entering surface of the first light-transmitting portion 11 can have identical or different structures. "Structure" here includes shape and size. The shapes of the first and second sequins 13, 14 can be circular, square, triangular, hexagonal, or a signature, etc.

[0039] Next, we will explain the second transparent member, which is located at one end of the first transparent member. The second transparent member includes a second light-transmitting portion 21 and a second mounting portion 22 for facilitating assembly of the second transparent member with other components. The second light-transmitting portion 21 is made of a light-transmitting material, while the second mounting portion 22 is made of an opaque material. The second light-transmitting portion 21 and the second mounting portion 22 may be manufactured using two-color injection molding.

[0040] Based on the above structure, a plurality of third sequins 23 are attached at intervals to the light-emitting surface of the second light-transmitting portion 21 facing the first light-transmitting portion 11. The third sequins 23 can be designed using, but not limited to, hot stamping, painting, aluminum plating, or chrome plating. It should be noted that the structure of the third sequins 23 can be the same as or different from that of the first and second sequins 13 and 14, and this is not an absolute limitation in this embodiment. The shape of the third sequins 23 can be circular, square, triangular, hexagonal, or a personal signature, etc.

[0041] Based on the above, it should be noted that the light incident surface of the second light-transmitting portion 21 facing the reflector 3 is a black surface. This surface can be painted black, and a plurality of light-entering holes 24 having different structures suitable for light transmission are provided at intervals on this light-entering surface. The light-entering holes 24 can be processed by, for example, but not limited to, laser engraving. The structures of the plurality of light-entering holes 24 on the light-entering surface of the second light-transmitting portion 21 can be the same or different, and this embodiment does not impose an absolute limitation on this.

[0042] Regarding the first light-transmitting portion 11 and the second light-transmitting portion 21 of this embodiment, in an optional implementation, the first light-transmitting portion 11 and the second light-transmitting portion 21 are parallel to each other, and the distance between the light-entering surface of the first light-transmitting portion 11 and the light-emitting surface of the second light-transmitting portion 21 is greater than 2 mm and less than 10 mm.

[0043] Next, let's talk about the reflector 3. It is fixed to the bracket 6 on the side of the second light-transmitting portion 21 facing away from the first light-transmitting portion 11. The end face of the reflector 3 facing the second light-transmitting portion 21 is a total reflection surface 31 composed of polyhedrons. Here, the total reflection surface 31 is formed by multiple raised polyhedrons, giving the total reflection surface 31 an overall diamond pattern. It should be noted that the total reflection surface 31 of the reflector 3 is arranged at an angle relative to the second transparent member, and the light-emitting member 4 is arranged diagonally above the reflector 3. Based on this structure, the light-emitting member 4 is adapted to emit light that is reflected by the total reflection surface 31 of the reflector 3 and then sequentially passes through the second transparent member and the first transparent unit to be emitted. In detail, referring to the accompanying drawings, for the reflector 3 arranged at an angle relative to the second transparent member, the distance between the bottom edge of the reflector 3 and the second transparent member is smaller than the distance between the top edge of the reflector 3 and the second transparent member, and the light-emitting member 4 is located above the top edge of the reflector 3. Under such a layout, the utilization rate of the total reflection surface 31 of the reflector 3 can be improved, so that more light emitted by the light-emitting member 4 is incident on the total reflection surface 31.

[0044] In summary, for the headlight optical module of this embodiment, through the reflection of the total reflection surface 31 of the reflector 3, in combination with the first sequins 13 designed on the light incident surface of the first light-transmitting portion 11, the second sequins 14 designed on the light exit surface of the first light-transmitting portion 11, and the third sequins 23 designed on the light exit surface of the second light-transmitting portion 21, the sequins on each surface layer produce a patchwork distribution when the light-emitting element 4 emits light, thereby achieving a sparkling, galaxy-like lighting effect with a suspended pattern. When the light-emitting element 4 does not emit light, a slight flashing effect can also be produced under the action of the external light source 5, such as sunlight, street lights, etc., that is, a sparkling effect can be achieved when the headlight is not lit. This enriches the lighting shape of the headlight of this application and enhances the uniqueness of its overall headlight shape.
