Description

Technical Field

[0001] The invention relates to the field of optical lenses, and in particular to a lens for achieving light homogenization. Background Art

[0002] In some lighting systems, in order to obtain lighting with minimal intensity variation, that is, a light beam with a uniform intensity profile, so as to obtain a clear imaging pattern or a light beam with a clear profile, a uniformizing optical device is sometimes used to convert the initial light beam into a light beam with a uniform intensity profile. Figure 4 As shown, most of the light homogenization devices currently used are traditional lenses, and traditional lenses are mostly plane mirrors 2. Therefore, during use, the light transmission efficiency is low and the light spot presented is uneven. After the initial light beam passes through the traditional lens 2, the formed light beam is still wide and the uniform intensity is low, making it difficult to form an imaging pattern with a clear contour. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a lens for achieving light homogenization, thereby solving the problems of low light transmission efficiency, uneven light spots and low uniform intensity of light beams existing in the existing traditional lenses, improving the light transmission efficiency and improving the uniform intensity of the light beam.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] A lens for achieving light homogenization comprises a lens body, wherein the lens body is arranged between a light source and a projection plane; the lens body is provided with two layers, the diameter of the first layer is smaller than that of the second layer, and the first layer and the second layer are formed into an integral structure; the second layer is a plane mirror; the lens body also comprises a specialized structure with an inner concave arc surface, and a plurality of light guide holes are evenly distributed on the specialized structure; the first layer is provided with a recessed structure adapted to the specialized structure; the specialized structure is fixedly arranged in the recessed structure.

[0006] Furthermore, the light guide hole is a regular hexagon, and the inner wall of the light guide hole is inclined toward the center of the light guide hole; the light guide holes are evenly distributed and closely arranged in an array. The closely arranged light guide holes can evenly separate the initial light beam, so that the light beam has higher uniformity after passing through the light guide hole.

[0007] The beneficial effects of the present invention are that it can effectively avoid the problems of low light transmission efficiency, uneven light spot and low uniform intensity of light beam existing in existing traditional lenses, improve the light transmission efficiency, improve the uniform intensity of the light beam, make the light beam profile clearer, and has a simple structure and is easy to manufacture. At the same time, it can be used in various lamps to achieve a homogenization effect on the light beam. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the following embodiments are based on the present technical solution and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to these embodiments.

[0014] like Figure 1 -3, a lens for achieving light homogenization includes a lens body 1; the lens body 1 is provided with two layers, the diameter of the first layer 11 is smaller than the second layer 12, and the first layer 11 and the second layer 12 are an integrally formed structure; the second layer 12 is a plane mirror; the lens body 1 also includes a specialized structure 13 with a concave arc surface, and a plurality of light guide holes 131 are evenly distributed on the specialized structure 13; the first layer 11 is provided with a recessed structure adapted to the specialized structure 13; the specialized structure 13 is fixedly arranged in the recessed structure.

[0015] like Figure 4As shown in FIG. 5 , in the above-mentioned lens for achieving light homogenization, when in use, the lens is placed between the light source and the target projection plane, and the specialized structure 13 with an inner concave arc surface can converge the initial light beam when it passes through, so that the overall light beam becomes narrower and the illumination effect is more concentrated. In addition, this design can increase the area of ​​the specialized structure 13 and increase the number of light guide holes 131, thereby enhancing the light homogenization effect. With the setting of the specialized structure 13, when the initial light beam is irradiated onto the lens body 1, the light beam passes through the light guide hole 131, and a light beam with uniform intensity can be generated. This light beam has a clear outline, uniform brightness, and good imaging effect. In addition, unlike the traditional lens 2, the final light beam is relatively narrow, with better focusing effect and uniform light spot, which improves the light transmission efficiency of the lens. At the same time, unlike most lenses, the lens body 1 is provided with two layers. The light beam is homogenized and concentrated by the first layer 11 having the specialized structure 13, and the homogenized light beam is further converged by the second layer 12 similar to a traditional plane lens, thereby extending the length of the refraction path of the lens, which is beneficial for more concentrated light beams and is also beneficial for installation in conjunction with specific components such as lamps.

[0016] In this embodiment, the material of the lens for achieving light homogenization can be glass, plastic or silicone material according to actual conditions.

[0017] Furthermore, the light guide hole 131 is a regular hexagon; the inner wall 1311 of the light guide hole 131 is inclined toward the center of the light guide hole 131; the light guide holes 131 are evenly distributed and closely arranged in an array. The closely arranged light guide holes 131 can evenly separate the initial light beam, so that the light beam has higher uniformity after passing through the light guide hole 131; and due to the setting of the light guide hole 131, the light transmission efficiency is high. By using the inclined inner wall of the light guide hole 131, the initial light beam becomes narrower after passing through the light guide hole 131, and can be more concentratedly irradiated on the projection plane, so that the light beam has higher brightness and higher uniformity, and a clearer image is achieved.

[0018] For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the present invention.
