Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interiors and relates to a vehicle atmosphere lighting optical device. Background Art

[0002] The light-transmitting medium of traditional atmosphere lights is designed to be relatively smooth. The head of the light-transmitting medium is relatively smooth in design, lacking effective optical reflection, so that the light directly penetrates from the light-transmitting medium, resulting in the formation of a dark area in this area. At the same time, the end face of the light-transmitting medium is the main light-emitting surface, and its brightness is relatively high, resulting in an overly bright phenomenon at the end position. Traditional atmosphere lights only have single-color lighting and cannot create a diverse and layered atmosphere for users. At the same time, the light distribution is uneven, there will be a dark area at the head position and an overly bright phenomenon at the end position. When the light at the end is too strong, a glare effect will be generated. This uneven light distribution will not only affect the visual comfort of passengers but also reduce driving safety. Summary of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a vehicle atmosphere lighting optical device for the problems of single-color lighting of traditional atmosphere lights, dark areas at the head, and high-brightness light at the tail, so that it can not only solve the problem of single-color lighting but also turn the disadvantage of uneven light distribution into an advantage. By setting an optical pattern structure in the light-transmitting body, the transmission effect is enhanced to effectively improve the brightness and avoid the occurrence of dark areas. By optimizing the layout of the light-transmitting body and the light-blocking body overlapping each other, the distribution and scattering of light are effectively controlled to avoid glare.

[0004] The technical solution of the utility model is as follows: A vehicle atmosphere lighting optical device described in the utility model includes a light-transmitting body, a light guide is arranged inside the light-transmitting body, a lamp body is arranged at the end of the light guide, and the light guide is arranged on one side of the light-transmitting body close to the lamp body.

[0023] The following further elaborates on the specific technical solutions of the present utility model in detail with reference to specific examples.

[0024] As shown in the figure, a vehicle ambient light optical device of the present utility model includes a lamp body 1, a light guide 2, a light guide bracket 3, an opaque body 4 and a light-transmitting body 5. The structure is simplified and lightweight. At the same time, the parts are dispersed to spread the heat source, which can more effectively increase the surface area, thereby improving the heat dissipation efficiency;

[0025] The lamp body 1 is arranged at the end of the light guide 2; by switching multi-color light sources, a multi-color ambient effect can be achieved. Users can select different light source colors according to their needs, thereby customizing the required lighting atmosphere;

[0026] The lamp body 1 can select a white light source, and preferably a multi-color light source, and a multi-color ambient effect is achieved by switching the light source.

[0027] The light guide 2 is arranged on one side inside the light-transmitting body 5 close to the lamp body 1. The center of the light guide 2 is opposite to the center of the light-transmitting body 5. The number of light guides 2 is the same as the number of light-transmitting bodies 5, which is greater than or equal to 1. The light guide 2 is used to conduct light A to ensure uniform distribution of light inside the entire light-transmitting body 5, providing a brighter and more uniform light output. At the same time, the energy consumption is low and the optical utilization rate is high;

[0028] The light guide bracket 3 plays a positioning and guiding role during installation to ensure that the light guide 2 can be accurately placed in the position expected by the designer, ensuring the reliability and stability of the light guide 2;

[0029] The light guide bracket 3 is arranged on one side above the light guide 2 close to the lamp body 1 for fixing the light guide 2.

[0030] The opaque body 4 is arranged below the lamp body 1, parallel to the lamp body 1, and on the same straight line as the light-transmitting body 5. The opaque body 4 is used to shield those areas or corners that do not need to be illuminated. By precisely designing and arranging the opaque body 4, it is possible to prevent light from directly shining into the eyes of the driver or passengers, reducing the impact of glare.

[0031] The arrangement shape and number of the light-transmitting bodies 5 in the optical device are set according to the requirements of the styling effect, with little restriction and high flexibility, which is convenient for personalized design and optimization of the visual effect, improving driving safety and riding comfort; and the number of the light-transmitting bodies 5 is greater than or equal to 1;

[0032] The light-transmitting body 5 can be selected as a light-transmitting body 5 with colors such as blue, red, purple, etc., which can effectively improve the lighting effect and aesthetics of the ambient light at a relatively low cost of the white light source;

[0033] The light-transmitting body 5 can be selected to have discrete powders or particles inside, so that the light generates heat dissipation, enhancing the heat dissipation effect of the light, and then achieving a more brilliant light-emitting effect, and ensuring the stability and performance during long-term use;

[0034] The light-transmitting body 5 is provided with an optical pattern structure 501, which changes the original smooth design, enhances the transmission effect, effectively improves the brightness, and avoids the occurrence of dark areas;

[0035] The optical pattern structure 501 is arranged on the inner surface of the light-transmitting body 5. The optical pattern structure 501 is in a serrated line pattern structure, receiving the main light ray A transmitted by the light guide 2. When passing through the optical pattern structure 501, it can change the light propagation path, increase the light scattering, thereby providing a more uniform lighting effect and avoiding the phenomena of glare and dark areas;

[0036] By adding the optical pattern structure 501 to the light-transmitting body 5, its transmission effect is optimized, effectively solving the problem of dark areas generated at the head of the ambient light;

[0037] A part of the extension of the light-transmitting body 5 is embedded in the light-blocking body 4 to form an overlapping light-transmitting body 502, which hinders the propagation of part of the main light ray A, so that the main light ray A will not be concentrated in a specific area, and at the same time takes into account the stability of the overall structure;

[0038] There are 3 overlapping light-transmitting bodies 502 in total. The thickness of the overlapping light-transmitting body 502 accounts for one-third to one-half of the thickness of the light-blocking body 4. Part of the main light ray A scattered by the optical pattern structure 501 is blocked at the overlapping light-transmitting body 502, effectively avoiding the problems of light concentration and local high brightness existing in traditional ambient lights, and providing a comfortable visual experience for passengers.

[0039] When the main light ray A transmitted by the light guide 2 passes through the scattering of the optical pattern structure 501, part of the scattered main light ray A is blocked at the overlapping light-transmitting body 502, thereby effectively reducing the glare effect caused by too high light brightness;

[0040] In addition, by optimizing the layout of the overlapping of the light-transmitting body 5 and the light-blocking body 4, the stability of the overall structure can be improved.

[0041] When the ambient light is turned on, the light ray A emitted by the lamp body 1 is transmitted through the light guide 2 and irradiates the optical pattern structure 501 on the inner surface of the light-transmitting body 5. After being scattered by the optical pattern structure 501, it irradiates into the light-transmitting body 5. The main light ray A evenly irradiates the required area inside the vehicle, avoiding glare and dark areas, and playing a role in improving driving safety.

[0042] The present utility model provides a vehicle ambient light optical device, which solves the problems of single-color illumination, dark areas appearing at the head, and high brightness of light at the tail, reduces the manufacturing cost, improves the heat dissipation performance, and through optical technology innovation, enhances the aesthetics and functionality of the ambient light, creating a more pleasant riding experience for passengers.
