Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a semi-transparent, semi-reflective thick-walled component structure and automotive lighting. Background Technology

[0002] With the rapid development of automotive lighting technology, while users demand diverse lighting designs, production costs and efficiency are also pressing issues for automotive lighting manufacturers. Currently, the traditional reflective thick-walled components in automotive lighting have parabolic or near-parabolic reflective surfaces, with surface treatments of transparency or aluminum plating. While this traditional design meets lighting needs, it reveals numerous drawbacks when multiple functions share a single light outlet.

[0003] Specifically, because traditional thick-walled reflective components have only one focal point, when multiple functions are required and different colors of light are emitted, both colors will deviate from this focal point. This defocusing phenomenon directly leads to energy loss, resulting in a significant reduction in luminous efficiency. To compensate for this reduction, power consumption often needs to be increased. Furthermore, the light patterns of each function will deviate due to defocusing, failing to achieve the expected optical effect and exhibiting unevenness. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem of defocusing when multiple functions share a single light outlet in the prior art, this utility model provides a semi-transparent and semi-reflective thick-walled component structure and vehicle lamp, which solves the problem of defocusing when multiple functions share a single light outlet, and has the effects of improving lighting uniformity, high luminous efficiency, and reducing power consumption.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a semi-transparent and semi-reflective thick-walled component structure, which includes: a first light source;

[0006] Second light source;

[0007] A thick-walled component body includes a multifunctional light guide surface and a light-emitting surface. The multifunctional light guide surface is disposed at one end of the thick-walled component body, and the light-emitting surface is disposed at the other end. The multifunctional light guide surface includes multiple first optical surfaces and multiple second optical surfaces, which are alternately arranged to form the multifunctional light guide surface. A first light source is disposed at one end of the thick-walled component body. A first light ray emitted by the first light source is reflected by the first optical surface and then emitted from the light-emitting surface. A second light source is disposed behind one end of the thick-walled component body. A second light ray emitted by the second light source is transmitted through the second optical surface and then emitted from the light-emitting surface. Specifically, the first light ray emitted by the first light source is reflected by the first optical surface and then emitted from the light-emitting surface, and the second light ray emitted by the second light source is transmitted through the second optical surface and then emitted from the light-emitting surface. This reflects and transmits light for different functions respectively, thereby achieving multiple light transmissions and avoiding the problem of defocusing when multiple functions share a single light outlet. This improves lighting uniformity, increases luminous efficiency, and reduces power consumption.

[0008] Furthermore, the first optical surface has a focal point or focal line, and the first light source is arranged to coincide with the focal point or focal line. The specific technical effect is that: the first optical surface is a surface with a focal point or focal line, and the first light source is placed at the focal point; the first light emitted from the light source, after being reflected by the first optical surface, can form a parallel beam or exit in a predetermined direction, greatly improving the focusing accuracy and collimation of the light.

[0009] Furthermore, the second optical surface does not have a focal point or focal line. The specific technical effect is to ensure that the second light emitted from the second light source is uniformly distributed after being transmitted through the second optical surface, thus improving the uniformity of illumination.

[0010] Furthermore, the first optical surface and the second optical surface are connected by a connecting surface, which is horizontally positioned.

[0011] Furthermore, the multifunctional light guide surface is provided with a diffusion pattern or texture. The specific technical effect is that the diffusion pattern or texture enables uniform light distribution, improving the uniformity of illumination.

[0012] Furthermore, the first optical surface is coated with aluminum. The specific technical effect is that the aluminum-coated first optical surface can reflect light more effectively, reduce light transmission and loss, and help improve the overall light efficiency.

[0013] Furthermore, the thick-walled component body is a transparent PC structure or a transparent PMMA structure.

[0014] Furthermore, the lower end of the thick-walled component body is recessed inward to form a light-entry groove, which has a hemispherical or semi-ellipsoidal structure. The specific technical effect is that the hemispherical or semi-ellipsoidal structure of the light-entry groove ensures that the light emitted from the first light source does not refract after entering the thick-walled component structure, thus guaranteeing not only the direction of light propagation but also propagation efficiency.

[0015] Furthermore, the surface of the light-incident groove is provided with a textured or patterned surface. The specific technical effect is that the diffusion pattern or textured surface can achieve a uniform distribution of light, improving the uniformity of illumination.

[0016] A vehicle headlight, comprising a semi-transparent, semi-reflective thick-walled component structure as described above.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention reflects the first light emitted by the first light source through the first optical surface and exits through the light-emitting surface, and transmits the second light emitted by the second light source through the second optical surface and exits through the light-emitting surface. By reflecting and transmitting light with different functions respectively, multiple light transmissions are achieved, avoiding the problem of defocusing when multiple functions are lit by sharing a single light-emitting port. This improves the uniformity of lighting, increases luminous efficiency, and reduces power consumption. Attached Figure Description

[0028] Figures 1 to 2 The image shown is a preferred embodiment 1 of the present invention. This embodiment has a semi-transparent and semi-reflective thick-walled component structure, which includes: a first light source 2, a second light source 3, and a thick-walled component body 1.

[0029] The thick-walled component body 1 includes a multifunctional light guide surface 101 and a light emitting surface 102. The multifunctional light guide surface 101 is disposed at one end of the thick-walled component body 1, and the light emitting surface 102 is disposed at the other end of the thick-walled component body 1. The multifunctional light guide surface 101 includes multiple first optical surfaces 1011 and multiple second optical surfaces 1012. The first optical surfaces 1011 and the second optical surfaces 1012 are arranged alternately multiple times to form the multifunctional light guide surface 101. The first light source 2 is disposed at one end of the thick-walled component body 1 and is located at the focal point of the first optical surface 1011. The first light emitted by the first light source 2 is reflected by the first optical surface 1011 and then emitted from the light emitting surface 102. The second light source 3 is disposed behind one end of the thick-walled component body 1. The second light emitted by the second light source 3 is transmitted through the second optical surface 1012 and then emitted from the light emitting surface 102. Thus, the first light emitted by the first light source 2 is reflected by the first optical surface 1011 and then emitted from the light-emitting surface 102, and the second light emitted by the second light source 3 is transmitted through the second optical surface 1012 and then emitted from the light-emitting surface 102. The light of different functions is reflected and transmitted respectively, thereby realizing the transmission of multiple light rays. This avoids the problem of defocusing when multiple functions are lit up by sharing a single light-emitting port, thereby improving the lighting uniformity, increasing the light efficiency, and reducing power consumption.

[0030] In this embodiment, the first optical surface 1011 has a focal point or focal line, and the first light source 2 is arranged coinciding with the focal point or focal line. Therefore, the first optical surface 1011 is a surface with a focal point or focal line, and the first light source 2 is positioned at the focal point. The first light emitted by the light source 2, after being reflected by the first optical surface 1011, can form a parallel beam or exit in a predetermined direction, greatly improving the focusing accuracy and collimation of the light. Specifically, the first optical surface 1011 is a parabolic surface, a near-parabolic surface, or a curved surface.

[0031] In this embodiment, the second optical surface 1012 does not have a focal point or focal line. Therefore, it ensures that the second light emitted from the second light source 3 is evenly distributed after being transmitted through the second optical surface 1012, improving the uniformity of illumination. Specifically, the first optical surface 1011 is planar, and can be vertically or inclined depending on actual usage requirements.

[0032] In this embodiment, the first optical surface 1011 and the second optical surface 1012 are connected by a connecting surface 1013, which is horizontally arranged.

[0033] In this embodiment, the multifunctional light guide surface 101 is provided with a diffusion pattern or texture. Therefore, the diffusion pattern or texture can achieve uniform light distribution and improve illumination uniformity. By adjusting the parameters of the diffusion pattern or texture, such as shape, size, and diffusion angle, the light beam can be shaped to meet specific application requirements.

[0034] In this embodiment, the first optical surface 1011 is plated with aluminum. Therefore, the aluminum-plated first optical surface 1011 can reflect light more effectively, reducing light transmission and loss, and thus helping to improve overall light efficiency.

[0035] In this embodiment, the thick-walled body 1 is a transparent PC structure or a transparent PMMA structure.

[0036] In this embodiment, the lower end of the thick-walled component body 1 is recessed inward to form a light-incident groove 103, which has a hemispherical or semi-ellipsoidal structure. Therefore, the hemispherical or semi-ellipsoidal structure of the light-incident groove 103 ensures that the light emitted from the first light source does not refract after entering the thick-walled component structure through the light-incident groove, thus guaranteeing not only the direction of light propagation but also propagation efficiency. Specifically, the diameter of the hemispherical or semi-ellipsoidal structure can be designed according to actual usage requirements.

[0037] In this embodiment, a textured or patterned surface can be provided on the light-incident groove 103. Therefore, the diffusion pattern or textured surface can achieve uniform light distribution and improve illumination uniformity.

[0038] In this embodiment, the light colors of the first light source 2 and the second light source 3 can be the same or different. For example, the first light source 2 is red light and the second light source 3 is yellow light, or both the first light source 2 and the second light source 3 are red light.

[0039] Example 2:

[0040] Based on Example 1, see Figures 3 to 4 As shown, a first light source 2 is provided at one end of the thick-walled component body 1. The first light source 2 can be either a single-core light source or a multi-core light source. The specific form is not limited here. In this embodiment, six single-core light sources are used as an example for explanation. The six single-core light sources are arranged sequentially along the first direction. Six sets of multifunctional light guide surfaces are also provided. The six sets of multifunctional light guide surfaces are arranged sequentially and connected along the first direction to form an integral thick-walled component structure. Each single-core light source is placed on the focal point or focal line of the first optical surface 1011 in its corresponding multifunctional light guide surface.

By reflecting and transmitting light of different functions respectively, multiple light transmissions are realized, avoiding the problem of defocusing when multiple functions are lit by sharing a single light-emitting port, thereby improving the lighting uniformity, increasing the light efficiency, and reducing power consumption.
