Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an optical pattern structure and an optical system. Background Technology

[0002] With the rapid development of automotive lighting technology and consumers' increasing pursuit of lighting effects, production costs and efficiency are also urgent issues for automotive lighting suppliers to address. In existing solutions, light emitted from LEDs passes through a series of processing devices before exiting from the light-emitting surface to achieve a more uniform lighting effect.

[0003] In traditional projects, reflective patterns are usually aligned quadrilaterals or polygonal structures, which can help with light distribution uniformity, but may not achieve the desired effect for special structures. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem of uneven illumination in the prior art, this utility model provides an optical pattern structure and an optical system, which uses staggered reflective surfaces to ensure that the light spreads evenly on both sides, and supplements the light to the areas with less light, thereby improving the uniformity of illumination.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an optical pattern structure, including a thick-walled body, the surface of which has a plurality of reflective surfaces arranged in an array, the reflective surfaces being uniformly staggered, parallel light incident on the reflective surfaces being uniformly diffused after being reflected by the reflective surfaces, and the reflective surfaces being staggered from the adjacent column of reflective surfaces in the horizontal direction by 1 / 2 the width of the reflective surfaces.

[0006] The optical pattern structure of this utility model arranges the reflective surfaces evenly and staggered, so that the light is reflected evenly by the reflective surfaces, thereby supplementing the darker areas and improving the uniformity of illumination.

[0007] Furthermore, to ensure the light diffusion effect, the angle between the reflective surface and the horizontal direction is 25°–50°.

[0008] Furthermore, the reflecting surface is an inclined surface or a curved surface.

[0009] Furthermore, in order to meet the needs of different usage scenarios, the reflective surfaces are staggered horizontally, vertically, or obliquely.

[0010] Furthermore, the projection of the reflective surface in the horizontal direction is rectangular.

[0011] Furthermore, the projection of the reflective surface in the horizontal direction is a parallelogram.

[0012] Furthermore, the projection of the reflective surface in the horizontal direction is a pentagon, hexagon, or other polygonal structure.

[0013] The technical solution adopted by this utility model to solve its technical problem is: an optical system, including a concentrator, wherein the light-emitting direction of the concentrator is provided with the above-mentioned optical pattern structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The optical pattern structure and optical system of this utility model arrange the reflective surfaces evenly at a specific distance, so as to diffuse the incident parallel light evenly in all directions, ensuring the regularity of light scattering, thereby achieving the effect of uniform lighting.

[0016] 2. The optical pattern structure and optical system of this utility model allow the reflective surfaces to be arranged in an alternating pattern in different directions. The light is supplemented by the staggered arrangement of the reflective surfaces, ensuring uniform illumination. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1, such as Figure 1 and Figure 2 As shown, an optical pattern structure includes a thick-walled body 1. The surface of the thick-walled body 1 has a plurality of reflective surfaces 2 arranged in an array. The reflective surfaces 2 are uniformly staggered and distributed. Parallel light incident on the reflective surfaces 2 is reflected by the reflective surfaces 2 and diffused uniformly. The reflective surfaces 2 are staggered from the adjacent column of reflective surfaces 2 by 1 / 2 the width of the reflective surfaces 2 in the horizontal direction.

[0033] Specifically, the reflective surfaces 2 are arranged in a staggered manner in the horizontal direction, and the projection of the reflective surfaces 2 in the horizontal direction is rectangular.

[0034] Specifically, the angle between the reflective surface 2 and the horizontal direction is 25°–50°. Preferably, the angle between the reflective surface 2 and the horizontal direction is 45°, as in this embodiment. The reflective surface 2 is a curved or inclined surface. A regularly arranged, staggered pattern is used to ensure uniform light distribution and reduce the complexity of light distribution.

[0035] like Figure 4 As shown, during normal use of vehicle lights, the concentrator converts the diffused light of the LED into parallel light. However, the incident parallel light will not be directly in front of the center of the reflector 2. In this case, the staggered reflector 2 can ensure that the light spreads in the left and right directions in the same way, and reduce some of the light to supplement the areas with less light, thereby improving uniformity.

[0036] Example 2 differs from Example 1 in that, as Figure 4 The reflective surfaces 2 are arranged in a staggered pattern in the longitudinal direction. Furthermore, each reflective surface 2 is not arranged uniformly in the horizontal direction, but is arranged in a uniform column in the vertical direction.

[0037] Example 3 differs from Example 1 in that, as Figure 5 The reflective surfaces 2 are inclined and staggered, and the reflective surfaces 2 are arranged in a uniform manner in the direction that is perpendicular to each other on the same plane.

[0038] Example 4 differs from Example 1 in that, as Figure 6 The reflecting surface 2 is a parallelogram.

[0039] Example 5 differs from Example 2 in that, as Figure 7 The reflecting surface 2 is a parallelogram.

[0040] Example 6 differs from Example 1 in that, as Figure 8 The reflecting surface 2 is a regular pentagon.

[0041] Example 7 differs from Example 2 in that, as Figure 9 The reflecting surface 2 is a regular pentagon.

[0042] Of course, the reflective surface is not limited to the above features; it can also be a regular hexagon or other polygonal structure.

[0043] like Figure 10 As shown, an optical system includes a concentrator 3, and the concentrator 3 has the aforementioned optical pattern structure in the light-emitting direction.

[0044] In summary, the optical pattern structure and optical system of this utility model, through the interlaced reflective surfaces, ensure that light diffuses equally to the left and right, and supplements the areas with less light, thereby improving the uniformity of illumination.

[0045] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
