Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a diffuse reflection vehicle lighting structure. Background Technology

[0002] With the rapid development of the automotive industry, LEDs have been increasingly used in vehicle lighting in recent years. To meet customer needs, vehicle lighting designs are no longer monotonous; while the shapes of vehicle lights have become more diverse, there is a greater pursuit of aesthetically pleasing, fashionable, and unique lighting effects, and vehicle lights are gradually becoming more intelligent.

[0003] Currently, the main design features of widely used vehicle headlights are: meeting regulations and uniformity. However, existing headlight lighting patterns suffer from monotony, resulting in a single and unattractive lighting effect. Headlights with a dazzling effect are aesthetically pleasing and have a good visual effect; however, existing dazzling headlights have complex optical structures, requiring reflective surfaces to be set on the edges, which increases costs, as exemplified by a vehicle lighting device disclosed in patent CN107076381B. Therefore, designing a low-cost, bright, dazzling, and sparkling reflector and headlight has become a demand for headlight manufacturers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a diffuse reflection vehicle light structure that has a brilliant lighting effect, relatively low cost, and high optical utilization.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The diffuse reflection headlight structure includes a light source and a reflector optical element, as well as a thick-walled component or reflector for changing the transmission path of light emitted from the light source. One side of the reflector optical element has an irregular faceted structure, and the other side of the reflector optical element is a reflective mirror surface. Light enters the reflector optical element, is reflected from the reflective mirror surface, and is then refracted through the faceted structure to form a dazzling lighting effect.

[0006] Further or preferred: The light source is located behind the optical elements of the reflector.

[0007] The other side of the optical element of the reflector is a smooth surface or a patterned surface, and the other side is provided with an aluminum plating layer, which forms the reflector surface.

[0008] The thick-walled component has an L-shaped optical structure, forming a closed loop for light rays, which then shine directly onto the surface of the reflector.

[0009] The edge of the optical element of the reflector is provided with a fixing structure.

[0010] The reflector is located above the optical element of the reflector.

[0011] The reflecting mirror surface is a parabolic surface or an inverted arc surface.

[0012] Compared with the prior art, this utility model has the following advantages: The diffuse reflection headlight has a reasonable structural design. One side of the reflector optical element has a faceted structure, while the other side is a smooth or textured surface. An aluminum-plated layer is provided on the reflective surface, which forms the reflector surface. It has a brilliant lighting effect, and the cost is relatively low. It has a high optical utilization rate, and the lighting effect and optical path are controllable. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0017] like Figure 1 and Figure 2 As shown, the diffuse reflection vehicle lamp structure 1 includes a lamp housing 2, an external lamp cover 3, a light source 4, a circuit board 5, a reflector optical element 6, and a thick-walled component 9 or a reflector 10; the light source 4 is mounted on the circuit board 5, and the circuit board and the reflector optical element are both located within the lamp cavity formed by the housing and the external lamp cover.

[0018] Thick-walled components or reflectors are mainly used to change the transmission path of light emitted from the light source. One side of the reflector optical element has a faceted structure 8, and the other side of the reflector optical element is a smooth surface or a patterned surface. Aluminum is plated on the smooth surface and the patterned surface to form a reflector surface 7. Light enters the reflector optical element, is reflected from the reflector surface, and is refracted through the faceted structure to form a dazzling lighting effect.

[0019] Preferably, the smooth surface of the reflector optical element 6 is provided with an aluminum plating layer, and the aluminum plating layer forms a reflector surface. The smooth surface is a parabolic surface or an inverted arc surface. Forming a reflector surface on a smooth surface has relatively low cost and stable and reliable quality.

[0020] The faceted structure is a raised, irregular polyhedron, consisting of several irregularly distributed polyhedrons; the light source is an LED light module; a set of LED light sources is set on the circuit board.

[0021] The light source is located behind the optical elements of the reflector, meaning the circuit board is located behind the optical elements of the reflector. This hidden design of the light source improves the quality of the product.

[0022] The thick-walled component is an L-shaped optical structure, with one end aligned with the light source. By altering the light path emitted from the light source, the thick-walled component directs the light from the light source onto the optical element of the reflector, forming a closed-loop light path that directly illuminates the reflector surface. The reflector is positioned above the optical element of the reflector; the light emitted from the light source strikes the reflector and is then reflected back onto the optical element of the reflector. The structure is integrated and compact. A fixing structure is provided at the edge of the optical element of the reflector. Alternatively, the thick-walled component can be designed as an inverted U-shape to achieve this optical path.

[0023] This utility model features a well-designed diffuse reflection vehicle light structure. One side of the reflector optical element has a faceted structure, while the other side is a smooth surface. An aluminum-plated layer is applied to the smooth surface, forming a reflector surface that provides a brilliant lighting effect and is relatively inexpensive.

[0024] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0025] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
