[0002] With the rapid development of the automotive industry, LEDs have been increasingly used in automotive lighting in recent years. To meet customer needs, automotive lighting designs are no longer monotonous; while headlight shapes have become more diverse, there is a greater pursuit of aesthetically pleasing, fashionable, and unique lighting effects. For example, creating various special lighting effects when illuminated. Current technologies often use structures such as light shields to block some light to achieve these special effects, but these shields lead to significant light waste. Therefore, to improve light utilization, an optical structure for creating unique lighting effects is proposed. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, this utility model proposes an optical structure with a unique lighting effect, which has the advantages of ensuring light utilization while presenting a special pattern.

[0005] The optical structure for the unique lighting effect according to an embodiment of this utility model includes: a collimation unit, a light guide assembly, and multiple microstructure patterns; the collimation unit is used to collimate the light emitted by the light source; one end of the light guide assembly is formed as a light-emitting surface, and the other end of the light guide assembly is formed as a light-incident surface; the light-incident surface is located on the light path of the collimation unit, and the light-incident surface is used to refract or reflect the light emitted by the collimation unit to the light-emitting surface; multiple microstructure patterns are spaced apart on the light-incident surface, and the microstructure patterns are used to change the path of the light they receive, so that the light energy in the region of the light-emitting surface corresponding to the region of the microstructure pattern is different from that in other regions.

[0006] According to one embodiment of the present invention, a diffusion pattern is formed on the microstructure pattern.

[0007] According to one embodiment of the present invention, the microstructure pattern is one or more of the following shapes: heart, star, rhombus, rectangle, triangle, and cross.

[0008] According to one embodiment of the present invention, the light incident surface is a reflective surface, the collimation unit is located on one side of the light guide assembly, and the light incident surface is an inclined surface formed at the other end of the light guide assembly.

[0009] According to one embodiment of the present invention, the light-incident surface is a curved surface.

[0010] According to one embodiment of the present invention, the light guide component is a thick-walled part, and the microstructure pattern is integrally formed with the light guide component.

[0013] According to one embodiment of the present invention, the collimation unit is a concentrator.

[0014] According to one embodiment of the present invention, the inclination angle of the light-incident surface is 40-50 degrees.

[0015] The beneficial effects of this utility model are that it uses multiple microstructure patterns spaced apart on the light-incident surface to diffuse the light after it has been collimated by the collimation unit.

[0027] The optical structure of the unique lighting effect of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-3 As shown, the optical structure for the unique lighting effect according to the embodiment of this utility model includes: a collimation unit 1, a light guide component 2, and multiple microstructure patterns 3; the collimation unit 1 is used to collimate the light emitted by the light source; one end of the light guide component 2 is formed as a light-emitting surface 21, and the other end of the light guide component 2 is formed as a light-incident surface 22; the light-incident surface 22 is located on the light path of the collimation unit 1, and the light-incident surface 22 is used to refract or reflect the light emitted by the collimation unit 1 to the light-emitting surface 21; multiple microstructure patterns 3 are distributed at intervals on the light-incident surface 22, and the microstructure patterns 3 are used to change the path of the light they receive, so that the light energy in the region of the light-emitting surface 21 corresponding to the region where the microstructure pattern 3 is located is different from that in other regions.

[0029] In this embodiment, the light source is located at the focal point of the collimation unit 1. The collimation unit 1 collimates the light emitted by the light source and directs it toward the light-emitting surface 21. The collimation unit 1 can be located at the other end of the light guide component 2 or on the side of the light guide component 2. When the collimation unit 1 is located at the other end of the light guide component 2, after the light is collimated by the collimation unit 1 and reaches the light-incident surface 22, part of the light is refracted through the light-incident surface 22 and then emitted onto the light-emitting surface 21. The point of this part of the light is relatively uniform, while the other part of the light is diffused after being refracted by the microstructure pattern 3. Therefore, the light-emitting area directly opposite the microstructure pattern 3 has relatively weak energy when viewed directly. Thus, through the diffusion of light by the microstructure pattern 3, the energy distribution of the illuminated area has a large difference, realizing the difference in brightness when illuminated, thereby displaying the pattern when viewed directly from the light-emitting surface 21; achieving a special illumination effect, while avoiding the waste of light and ensuring the utilization rate of light. Furthermore, the light diffused by the microstructure pattern 3 increases the viewing angle, meaning that the light can still be seen even at a certain angle away from the direct view of the light-emitting surface 21. When the collimating unit 1 is located to the side of the light guide assembly 2, the light collimated by the collimating unit 1 enters the light guide assembly 2 and hits the light-incident surface 22. After being reflected by the light-incident surface 22, it reaches the light-emitting surface 21 (e.g., ...). Figure 2 (The dashed path in the image), similarly, when light hits the microstructure pattern 3, the light diffuses (as shown in the image). Figure 2 (The solid line path in the image) thus achieves the same special lighting effect while avoiding the waste of light.

[0030] The microstructure pattern 3 has a pattern with a diffusion angle. The pattern of the microstructure pattern 3 can be a polyhedral pattern, which can protrude from the light guide component 2 or be recessed into the light guide component 2, and has a multi-angle cut surface. The size and angle of the cut surface can be randomly distributed.

[0031] The microstructure pattern 3 is shaped like one or more of the following: heart, star, rhombus, rectangle, triangle, cross, and letter. Microstructure pattern 3 is made of transparent material.

[0032] Specifically, it can be set as a combination of single shapes or a mixture of multiple shapes, depending on the requirements.

[0033] The light-incident surface 22 is a reflective surface. The collimating unit 1 is located on one side of the light guide assembly 2, and the light-incident surface 22 is an inclined surface formed at the other end of the light guide assembly 2. The inclination angle of the light-incident surface 22 is 25-50 degrees, preferably 45 degrees. That is, an inclined surface with a 45-degree angle to the light emitted from the collimating unit 1 is formed at the other end of the light guide assembly 2. This inclined surface is the light-incident surface 22, and the inclined surface can be a curved surface or a plane. That is, the inclined surface is formed by stretching a contour line in a vertical plane along the length direction (horizontal direction) of the light guide assembly 2. The contour line can be a curve or a straight line, and the stretching direction can be determined according to the shape of the light guide assembly 2. It can be a straight line or a curve. Therefore, when the contour line and / or the stretching direction is a curve, the inclined surface is a curved surface, which can achieve the effect of collecting light and increase the light efficiency. The specific light-collecting direction can be set according to the requirements. When the contour line is a straight line and the stretching direction is a straight line, the inclined surface is a plane, which can ensure the collimation of the light. When the stretching direction is a straight line, it can be parallel to or gradually approach the light-emitting surface 21. A reflective layer is formed on the area of ​​the light-receiving surface 22 other than the microstructure pattern 3. The reflective layer can be an aluminum layer.

[0034] The light guide component 2 is a thick-walled part, and the microstructure pattern 3 is integrally formed with the light guide component 2, which can be manufactured by injection molding.

[0035] Microstructure pattern 3 is a polyhedral pattern.

[0036] Collimation unit 1 is a condenser or other structure that can achieve light collimation.
