Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an optical structure, automotive lighting, and automobile that can improve light uniformity and light efficiency. Background Technology

[0002] With the development of automotive lighting technology, headlight designs are becoming increasingly diverse, making the uniformity and aesthetics of illumination a critical issue for suppliers. In existing technologies, light emitted from LEDs typically exits through direct or reflective structures from the light-emitting surface to achieve uniform illumination. However, traditional solutions (such as reflector structures) are limited by space and shape, resulting in insufficient uniformity over large angles and low light efficiency. Therefore, a novel optical structure is urgently needed that can efficiently and uniformly distribute light, save space, and improve luminous efficacy. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a uniformly illuminated optical structure, a vehicle headlight, and an automobile. This optical structure can solve the problems of insufficient light uniformity and low light efficiency in existing technologies, while simultaneously meeting the requirements of aesthetics and space saving in vehicle headlights.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An optical structure with uniform illumination, comprising:

[0006] The first optical unit is a light-concentrating structure at the light-incident end.

[0007] The second optical unit is disposed above the first optical unit, and the second optical unit is a reflective structure;

[0008] The incident light is converged by the first optical unit and then reflected by the second optical unit to achieve uniform light output.

[0009] The first optical unit has a focal point or focal line, and the inner wall of the second optical unit is provided with a pattern for reflecting and uniformly distributing light.

[0010] By combining the first optical unit (focusing structure) and the second optical unit (reflection structure), the light is first focused and then reflected, optimizing the light path distribution and improving the uniformity of light output.

[0011] The second optical unit is positioned above the first optical unit, which maximizes space utilization and is suitable for applications in confined spaces such as vehicle lights.

[0012] Furthermore, the first optical unit is a circular condenser, a nested condenser, or a stretched condenser. A circular condenser is suitable for conventional optical needs, a nested condenser can improve focusing efficiency, and a stretched condenser is suitable for asymmetric optical path designs, which can improve the applicability of the first optical unit.

[0013] Furthermore, the surface of the first optical unit is patterned. The surface pattern can further scatter light, reduce the light spot effect, and make the light distribution more uniform.

[0014] Furthermore, the first optical unit has one or two focal points. A single focal point is suitable for simple converging needs, while a dual focal point can optimize complex optical paths and improve light efficiency.

[0015] Furthermore, an aluminum-plated layer is provided on the inner surface of the second optical unit. The aluminum-plated layer can completely cover the inner surface of the second optical unit or partially cover it. The aluminum-plated layer can enhance light reflection efficiency, reduce light energy loss, and improve overall light efficiency.

[0016] Furthermore, the second optical unit is a multi-faceted splicing structure, with the faces being one or two of inclined planes and curved surfaces. The combination of inclined planes or curved surfaces allows for flexible adjustment of the reflection angle, adapting to different vehicle headlight designs and regulatory requirements.

[0017] Furthermore, the second optical unit is a focalless reflection mechanism. The focalless design avoids excessive light concentration, ensures uniform light distribution, and avoids localized over-brightness or under-brightness.

[0018] Furthermore, the second optical unit is a focal-line-less reflection mechanism. The focal-line-less design avoids excessive light concentration, ensures uniform light distribution, and avoids localized over-brightness or under-brightness.

[0019] A vehicle light, the vehicle light comprising the aforementioned optical structure for uniform illumination.

[0020] An automobile, including the aforementioned headlights.

[0021] The beneficial effects of this utility model are as follows: This utility model has a simple structure and reasonable design, and has the following advantages:

[0022] (1) Significantly improved light uniformity: Through the synergistic effect of the first optical unit (focusing light), the second optical unit (reflection), and the pattern on the inner wall of the second optical unit, the light spot problem of traditional car lights is eliminated;

[0023] (2) High light efficiency, aluminum-plated reflective structure and optimized light-concentrating design reduce light energy waste, making it energy-saving and efficient;

[0024] (3) The structure is flexible and adaptable. The light-concentrating structure of the first optical unit, the multi-faceted splicing structure of the second optical unit, and the patterns of the first and second optical units can all be customized, which is suitable for different car light shapes and regulatory requirements.
