Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, specifically to a light distribution element, an automotive lamp, and a vehicle. Background Technology

[0002] Current automotive headlight designs typically incorporate fisheye or relatively regular patterns on the lens to meet light distribution regulations. However, this approach results in monotonous and homogenized patterns. When the headlights are off, their visibility is poor, lacking originality. When illuminated, they only present a planar light emission effect, lacking depth. This leads to a significant reduction in overall brightness when viewed from a wide angle, compromising driving safety. Utility Model Content

[0003] The purpose of this application is to provide a light distribution element, a vehicle lamp, and a vehicle that enables the vehicle lamp to have a three-dimensional light emission effect, so as to obtain higher visual brightness when observing the vehicle lamp at a large angle, thereby improving driving safety.

[0004] To solve the above-mentioned technical problems, this application provides a light distribution element, which has a light distribution region. The light distribution region has a curved surface structure and is provided with a light distribution pattern. The light distribution pattern includes a plurality of arrayed light distribution pattern units. Each light distribution pattern unit includes a first light distribution plane, a second light distribution plane, a third light distribution plane, and a fourth light distribution plane. Each light distribution plane has a pentagonal structure, and the normal directions of each light distribution plane are different.

[0005] The first light distribution plane and the second light distribution plane share a common first side, and the third light distribution plane and the fourth light distribution plane are located at opposite ends of the extension direction of the first side, wherein:

[0006] The third light distribution plane includes an adjacent second side and a third side. The third light distribution plane and the first light distribution plane share the second side, and the third light distribution plane and the second light distribution plane share the third side. One endpoint of the first side, the second side, and the third side coincides.

[0007] The fourth light distribution plane includes an adjacent fourth side and a fifth side. The fourth light distribution plane and the first light distribution plane share the fourth side, and the fourth light distribution plane and the second light distribution plane share the fifth side. One endpoint of the first side, the fourth side, and the fifth side coincides.

[0008] Because the light distribution area of ​​the light distribution element in this application has a curved structure and a light distribution pattern, the light distribution pattern includes multiple arrayed light distribution pattern units. Each light distribution pattern unit has four pentagonal light distribution planes, and the normal directions of each light distribution plane are different. Therefore, each light distribution pattern unit is a three-dimensional, diamond-like structure. When lit, the light from the light source can be emitted from each light distribution plane of each light distribution pattern unit at different angles, presenting a diamond-like brilliant and sparkling three-dimensional light-emitting effect. This allows the observer to see more light when viewing the headlight using the above-mentioned light distribution element from a large angle, thereby obtaining higher visual brightness and improving driving safety. In addition, when not lit, each light distribution plane of each light distribution pattern unit can reflect and / or refract natural light into different angles. Therefore, even when not lit, it also has a diamond-like three-dimensional brilliant visual effect, with high recognizability, providing users with a differentiated experience.

[0009] Optionally, the two endpoints of the first side are the first endpoints;

[0010] The endpoint of the second side, the third side, the fourth side, and the fifth side that is furthest from the first side is the second endpoint;

[0011] In each light distribution plane, the endpoints other than the first endpoint and the second endpoint are the third endpoints;

[0012] The first endpoint is located on the first surface, the second endpoint is located on the second surface, and the third endpoint is located on the third surface. The first surface, the second surface, and the third surface are arranged sequentially from the outside to the inside.

[0013] When the light distribution element is installed in the vehicle lamp, the direction closer to the inside of the vehicle lamp is called the inside, and the direction closer to the outside of the vehicle lamp is called the outside.

[0014] Optionally, the length of the first side is D1, the side in the third light distribution plane that is far from the second side and the third side is the sixth side, the side in the fourth light distribution plane that is far from the fourth side and the fifth side is the seventh side, and the distance between the sixth side and the seventh side is D2, where D2 = 2D1.

[0015] Optionally, each of the light distribution planes is a regular pentagonal structure.

[0016] Optionally, the light distribution pattern has multiple rows of light distribution pattern groups, each row of the light distribution pattern group includes multiple light distribution pattern units distributed along a first direction, and in the same light distribution pattern group, the line connecting the midpoints of the first side in each light distribution pattern unit is parallel to the boundary line extending along the first direction in the light distribution region.

[0017] Optionally, in two adjacent rows of light distribution pattern groups, the midpoints of the first side of each light distribution pattern unit are staggered.

[0018] Optionally, in the same light distribution pattern group, the line connecting the midpoints of the first side in each light distribution pattern unit is defined as a first curve, and the distance between two adjacent first curves is equal.

[0019] This application also provides a vehicle lamp, which includes the aforementioned light distribution element.

[0020] The vehicle headlights of this application include the aforementioned light distribution element, and therefore have the same technical effects as the aforementioned light distribution element, which will not be repeated here.

[0021] Optionally, the vehicle light includes a thick-walled member and / or an inner lamp cover, wherein the thick-walled member and the inner lamp cover, one of which is closer to the interior of the vehicle light, forms the light distribution element.

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the light distribution pattern in the light distribution element provided in this application; Figure 2 for Figure 1 Schematic diagram of the structure of the central light distribution pattern unit; Figure 3 for Figure 1 One of the state diagrams in the process of forming the light distribution pattern.

[0033] This embodiment provides a light distribution element, which has a light distribution region a, which is a curved surface structure. The light distribution region a is provided with a light distribution pattern, which includes a plurality of arrayed light distribution pattern units 1. The light distribution pattern unit 1 includes a first light distribution plane 11, a second light distribution plane 12, a third light distribution plane 13 and a fourth light distribution plane 14. Each light distribution plane is a pentagonal structure and the normal direction of each light distribution plane is different.

[0034] The first light distribution plane 11 and the second light distribution plane 12 share a common first side L1, and the third light distribution plane 13 and the fourth light distribution plane 14 are located at both ends of the extension direction of the first side L1, wherein:

[0035] The third light distribution plane 13 includes an adjacent second side L2 and a third side L3. The third light distribution plane 13 and the first light distribution plane 11 share the second side L2. The third light distribution plane 13 and the second light distribution plane 12 share the third side L3. One endpoint of the first side L1, the second side L2 and the third side L3 coincides.

[0036] The fourth light distribution plane 14 includes an adjacent fourth side L4 and a fifth side L5. The fourth light distribution plane 14 and the first light distribution plane 11 share the fourth side L4, and the fourth light distribution plane 14 and the second light distribution plane 12 share the fifth side L5. One endpoint of the first side L1, the fourth side L4 and the fifth side L5 coincides.

[0037] Because the light distribution area a of the light distribution element in this embodiment is a curved surface structure, and the light distribution area a is provided with a light distribution pattern, the light distribution pattern includes multiple arrayed light distribution pattern units 1. Each light distribution pattern unit 1 has four pentagonal light distribution planes, and the normal directions of each light distribution plane are different. Therefore, each light distribution pattern unit 1 is a three-dimensional, diamond-like structure. When lit, the light from the light source can be emitted from each light distribution plane of each light distribution pattern unit 1 at different angles, presenting a diamond-like brilliant and sparkling three-dimensional light-emitting effect. This allows the observer to see more light when viewing the car headlight using the above-mentioned light distribution element from a large angle, thereby obtaining higher visual brightness. In addition, when not lit, each light distribution plane of each light distribution pattern unit 1 can reflect and / or refract natural light into different angles. Therefore, even when not lit, it also has a diamond-like three-dimensional brilliant visual effect, with high recognizability, providing users with a differentiated experience.

[0038] Please continue to refer to this. Figure 2 Define the two endpoints of the first side L1 as the first endpoint A1;

[0039] The endpoint furthest from the first side L1 among the second side L2, the third side L3, the fourth side L4, and the fifth side L5 is the second endpoint A2;

[0040] In each light distribution plane, the other endpoints besides the first endpoint A1 and the second endpoint A2 are designated as the third endpoint A3;

[0041] The first endpoint A1 is located on the first surface, the second endpoint A2 is located on the second surface, and the third endpoint A3 is located on the third surface. The first surface, the second surface, and the third surface are arranged in order from the outside to the inside.

[0042] When the light distribution element is installed in the headlight, the direction closer to the inside of the headlight is called the inside, and the direction closer to the outside of the headlight is called the outside.

[0043] As set above, in this embodiment, the light distribution pattern unit 1 is a three-dimensional structure with the central area protruding outward and the edge curves concave inward, similar to the structure of a diamond. It has a three-dimensional and dazzling visual effect whether it is lit or not, which enhances the refinement of the headlights and the whole vehicle and improves the user experience.

[0044] It can be understood that the light distribution region a is a curved surface structure with a certain thickness. The first curved surface, the second curved surface, and the third curved surface are arranged sequentially along the thickness direction of the light distribution region a, and the distance between the first curved surface and the third curved surface does not exceed the thickness of the light distribution region a.

[0045] Furthermore, such as Figure 2As shown, in this embodiment, the length of the first side L1 is D1, the side of the third light distribution plane 13 that is far away from the second side L2 and the third side L3 is the sixth side L6, the side of the fourth light distribution plane 14 that is far away from the fourth side L4 and the fifth side L5 is the seventh side L7, and the distance between the sixth side L6 and the seventh side L7 is D2, where D2 = 2D1.

[0046] As set up above, the distance between the sixth side L6 and the seventh side L7 is twice the length of the first side L1. This not only meets the light distribution requirements of the light distribution regulations, but also ensures that the diffusion angles of the four light distribution planes remain consistent, effectively improving the uniformity of the light.

[0047] In this embodiment, each light distribution plane is a regular pentagonal structure.

[0048] With the above settings, the structure of each light distribution plane is the same, and the structure of each light distribution plane is more regular. On the one hand, the visual effect is more uniform when lit; on the other hand, the light distribution pattern is also easy to process and implement.

[0049] Please continue to refer to this. Figures 1-3 In this embodiment, the light distribution pattern has multiple rows of light distribution pattern groups. Each row of light distribution pattern groups includes multiple light distribution pattern units 1 distributed along the first direction 001. In the same light distribution pattern group, the line connecting the midpoint O of the first side L1 in each light distribution pattern unit 1 is parallel to the boundary line a1 extending along the first direction 001 in the light distribution region a.

[0050] As set up above, the arrangement of each light distribution pattern unit 1 is more suitable for the structure of the light distribution area a, so that each light distribution pattern unit 1 can fill the entire light distribution area a; at the same time, the structures of multiple rows of light distribution pattern groups are similar, making them easier to design, easier to process, and easier to implement.

[0051] Furthermore, in two adjacent rows of light distribution pattern groups, the midpoint O of the first side L1 in each light distribution pattern unit 1 is staggered from each other.

[0052] In other words, in two adjacent rows of light distribution pattern groups, the light distribution pattern unit 1 in the first row and the light distribution pattern unit 1 in the second row are not in a one-to-one correspondence. The staggered arrangement further increases the visual variation effect, making the light distribution pattern more layered and richer.

[0053] Furthermore, in the same light distribution pattern group, the line connecting the midpoints O of the first side L1 in each light distribution pattern unit 1 is defined as the first curve c1, and the distance between two adjacent first curves c1 is equal.

[0054] As set up above, each row of light distribution pattern groups is evenly distributed within the light distribution area a, resulting in a more uniform luminous effect when lit.

[0055] In this embodiment, the design process of the light distribution pattern unit 1 is as follows:

[0056] A first surface is selected on the light distribution area a, and a series of first curves c1 extending along the first direction 001 are made on the first surface. The first curves c1 are parallel to the boundary line a1 extending along the first direction 001 in the light distribution area a. The distance between two adjacent first curves c1 is equal. Multiple base points are selected on each first curve c1, and the base points between two adjacent first curves c1 are staggered.

[0057] Extending the base point as the center point and extending the same distance in opposite directions to both ends, we obtain the first side L1. It can be seen that the base point is also the midpoint O of the first side L1. The two endpoints of the first side L1 are the first endpoints A1. Rotating the first side L1 with the two endpoints as the center points, we obtain four line segments of the same length as the first side L1. Offsetting the first surface inward by a certain distance, we obtain the second surface. Projecting the endpoints of the line segments of the same length as the first side L1 that are far away from the first side L1 onto the second surface, we obtain four second endpoints A2. Connecting the first endpoints A1 and the corresponding second endpoints A2, we obtain the second side L2, the third side L3, the fourth side L4, and the fifth side L5. The first side L1, the second side L2, the third side L3, the fourth side L4, and the fifth side L5 are of the same length.

[0058] Rotate the second side L2 around the corresponding second endpoint A2 as the center point to obtain two line segments of the same length as the second side L2. Offset the second curved surface inward by a certain distance to obtain the third curved surface. Project the other endpoint of the line segment of the same length as the second side L2 away from the second side L2 onto the third curved surface to obtain two third endpoints A3. Perform the same operation on the third side L3, the fourth side L4 and the fifth side L5. Connect the third endpoints A3 on the third curved surface in sequence to obtain four closed regular pentagonal surfaces, thus obtaining a diamond-like light distribution pattern unit 1.

[0059] By moving the aforementioned light distribution pattern unit 1 to the positions of each base point and combining all the light distribution pattern units 1 together, a complete light distribution pattern can be obtained.

[0060] This embodiment also provides a vehicle lamp, which includes the aforementioned light distribution element.

[0061] The headlight in this embodiment includes the aforementioned light distribution element, and therefore has the same technical effect as the aforementioned light distribution element, which will not be described again here.

[0062] Specifically, in some embodiments, the vehicle lamp includes a thick-walled member and / or an inner lamp cover, which are installed inside the outer lamp cover. Both the thick-walled member and the inner lamp cover have a light guiding function, and the one of the thick-walled member and the inner lamp cover that is closer to the inside of the vehicle lamp forms the aforementioned light distribution element.

[0063] This embodiment also provides an automobile, including the aforementioned vehicle lights.

[0064] The vehicle in this embodiment includes the aforementioned headlights, and therefore has the same technical effects as the aforementioned headlights, which will not be described again here.

[0065] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
