[0003] The inner side end of the conventional thick wall spare serves as an optical surface for receiving light emitted by the light source, and the outer side end of the thick wall spare is designed as a light emitting surface for emitting light outward. Meanwhile, a plurality of reflecting surfaces are arranged at the inner side end optical surface of the thick wall spare for improving the utilization rate and uniformity of light. A convex grid-shaped light distribution pattern is formed on the outer side end light emitting surface of the thick wall spare, and a step slope is left at the edge, which helps the light to be better diffused and uniformly distributed.
[0004] The existing car light modeling requires that a plurality of function light sources share one thick wall spare of the car light, and the thick wall spare is designed using the center points of the focal points of the plurality of light sources, so that the function light sources are completely out of focus relative to the optical surface, resulting in poor lighting effect.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0037] The core of this utility model is to provide an optical system, vehicle lights, and a vehicle that can achieve uniform illumination of various functional signal lights.
[0038] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] For details, please refer to Figures 1-6 , Figure 1 A schematic diagram of the structure of an optical system provided in an embodiment of this utility model; Figure 2 A schematic diagram of the optical principle of an optical system provided in an embodiment of this utility model; Figure 3 A partial structural schematic diagram of the collimator provided in an embodiment of this utility model; Figures 4-5 Schematic diagrams of the thick-walled component from different perspectives provided in the embodiments of this utility model; Figure 6 Rear view of a thick-walled component provided in an embodiment of this utility model.
[0040] The present invention provides an optical system including a thick-walled member 100 and at least one light source assembly 200. At least one collimator 110 is provided on the light-incident side of the thick-walled member 100, and the collimator 110 corresponds one-to-one with the light source assembly 200.
[0041] Thick-walled components, as an important optical part in automotive lights, are mainly responsible for conducting and distributing the light emitted by the light source assembly 200, so that the light can be evenly irradiated onto the light-emitting surface of the headlight, thereby improving the lighting effect and visual experience of the headlight. Collimator 110 is used for light collection and optical path adjustment. To adapt to the design of the headlight device, collimator is usually cut to adjust the shape of the light-emitting surface of collimator 110.
[0042] Each collimator 110 panel includes multiple optical surface groups, and each optical surface group includes multiple optical surfaces.
[0043] The light source assembly 200 includes multiple light sources with different functions arranged side by side, each light source corresponding to an optical surface group, and each light source is located at the focal point of its corresponding optical surface group.
[0044] The optical surfaces of different optical surface groups are arranged alternately in the same order. Different optical surface groups are used to achieve different vehicle lighting functions.
[0045] This solution provides an optical system in which at least one collimator 110 is mounted on a thick-walled component 100. Each collimator 110 corresponds to a light source assembly 200, and each light source assembly 200 contains multiple light sources with different functions. Each collimator 110 has multiple optical surface groups arranged on it, with each optical surface group corresponding to a single function of the light source. Each light source is located at the focal point of its corresponding optical surface group, and the optical surfaces of different optical surface groups are arranged alternately in the same order. This ensures that the focal points of multiple light sources in the light source assembly 200 correspond to multiple optical surfaces that are spaced apart and arranged close together, guaranteeing the optical effects of multiple functional light sources and enabling uniform illumination of various functional signal lights. Simultaneously, the defocused optical surfaces can supplement the large-angle optical effect, ensuring cost reduction while meeting regulatory requirements and achieving uniform illumination.
[0046] In a specific embodiment, the multiple light sources of the light source assembly 200 are multiple light sources with different functions.
[0047] For example, the light source assembly 200 employs a single light source with multiple light-emitting units, using a single light source but generating multiple light-emitting points or areas through some means. This technology can achieve complex lighting effects or display functions while maintaining the simplicity of the light source system.
[0048] For example, the light source assembly 200 can also use light sources of different colors, such as dual-color light sources, tri-color light sources, or even more colors of light sources. The specific selection can be made according to the actual functional requirements of the vehicle lights, and no further limitations are made here.
[0049] like Figures 1-2 In the optical system shown, multiple optical surface groups include a first optical surface group and a second optical surface group. The first optical surface group includes multiple first optical surfaces 111, and the second optical surface group includes multiple second optical surfaces 112. The first optical surfaces 111 and the second optical surfaces 112 are arranged alternately to form multiple optical surfaces with concave and convex spacing.
[0050] The multiple light sources include a first light source 210 and a second light source 220, where the first light source 210 corresponds to a first optical surface group and the second light source 220 corresponds to a second optical surface group.
[0051] To enhance the lighting effect, the optical surface of the collimator 110 is a transparent part with total internal reflection function, which allows multiple optical surface groups to reflect and collimate the light incident on it outward.
[0052] In one specific embodiment, the first light source 210 and the second light source 220 are a dual-color LED or two LEDs.
[0053] The first light source 210 uses a white LED chip. The light emitted by the first light source 210 is reflected by multiple first optical surfaces of the collimator 110 (including the 2nd, 4th, 6th... rows from left to right).
[0054] The second light source 220 uses a yellow LED chip. The light emitted by the second light source 220 is reflected by multiple second optical surfaces of the collimator 110 (including the 1st, 3rd, 5th, 7th... rows from left to right).
[0055] The thick-walled component 100 is provided with a plurality of collimators 110 arranged side by side. Each collimator 110 corresponds to the first light source 210 and the second light source 220. Each collimator 110 has a plurality of optical surfaces arranged with concave and convex intervals.
[0056] By adopting the concept of matrix optics, the rows of optical surfaces of each collimator 110 are spaced apart. This way, each light source has multiple optical surfaces that are spaced apart and arranged in close proximity, which can solve the problem of the inability to achieve a balance of multiple functional optical effects caused by multiple light source focal points.
[0057] When in operation, different colored LEDs can be lit to achieve different brightness levels in the vehicle lights. For example, the DRL (daytime running light) function lights up a white LED with a 100% duty cycle; the PO (position, etc.) function lights up a white LED with a 10% duty cycle; and the DI (front turn signal) function lights up a yellow LED with a 100% duty cycle.
[0058] In a specific embodiment, the side of the thick-walled component 100 is provided with a textured surface, which can enhance the lighting effect in that area.
[0059] When there are multiple collimators 110, the multiple collimators 110 are arranged side by side. The thick-walled component 100 is V-shaped as a whole.
[0060] Furthermore, this utility model also provides a vehicle lamp, including the optical system described in the above-described specific embodiments. This utility model also provides a vehicle, including the vehicle lamp described in the above-described specific embodiments.
[0061] Obviously, the headlights containing the above-mentioned optical system and the vehicles containing the above-mentioned headlights have the same beneficial effects, which will not be elaborated here.
