Description

Technical Field

[0001] This utility model relates to the field of prism plate technology, specifically to a prism plate with uniform light output. Background Technology

[0002] In the field of optics, prisms are important optical components. They mainly use the microstructure of their surface to change the direction of light emitted from the light source, thereby achieving anti-glare and light mixing. Currently, the two main types of conventional microstructure prisms commonly found on the market are as follows.

[0003] The first type is a multi-faceted conical microstructure prism plate. The microstructure of this type of prism plate presents a regular square pyramid, hexagonal pyramid, or similar shape. These microstructures are arranged in a linear, equidistant array in two directions on the plane (hexagonal pyramids are sometimes arranged along the six sides of a hexagon). This structural design allows for a certain degree of anti-glare and slight light mixing. However, during light mixing, due to the regular shape of the microstructure, it easily forms an image on the light spot, resulting in bright spots that match the shape of the microstructure. This imaging problem is particularly problematic when dealing with multi-colored light sources, making it difficult to achieve uniform mixing of multiple colors. Furthermore, color layering easily occurs between different colors, significantly affecting the mixing effect and light quality.

[0004] The second type is the beaded microstructure prism plate. This type of prism plate has a regular beaded microstructure, also arranged linearly and equally spaced in two directions on a plane, or filled along the six sides of a hexagon, to achieve anti-glare and light mixing effects. However, because there are non-intersecting areas between the beaded surfaces, even with a linear array, imaging issues can occur, resulting in noticeable secondary light spots. This problem makes it difficult to achieve uniform light mixing when dealing with multi-color light sources, failing to meet the requirements for high-quality light mixing effects.

[0005] In summary, existing conventional microstructure prisms have significant limitations in light mixing effects when dealing with multi-color light sources. There is an urgent need to develop a new prism structure to solve the problem of uniform light mixing of multi-color light, so as to improve the performance and application effect of optical products in complex lighting environments.

[0021] The components are: 1. Body; 2. Hemispherical microstructure; 3. Reflector; 4. Lens. Detailed Implementation

[0022] The present invention will be further described in conjunction with the following embodiments.

[0023] Depend on Figures 1 to 2 As can be seen, the prism plate with uniform light emission described in this embodiment includes a body 1; a plurality of hemispherical microstructures 2 are arranged in a matrix on one side of the body 1; the plurality of hemispherical microstructures 2 are arrayed in a planar regular hexagonal intersecting manner.

[0024] Specifically, the uniformly light-emitting prism plate described in this embodiment achieves good light mixing effect by setting the matrix-arranged microstructures to a hemispherical shape; and by arranging multiple hemispherical microstructures 2 in a planar hexagonal intersecting manner, that is, each hemispherical microstructure 2 has six hemispherical microstructures 2 arranged on its outer periphery, and these six hemispherical microstructures 2 are arranged in a planar hexagonal intersecting manner on the outer periphery of the central hemispherical microstructure 2; by arranging multiple hemispherical microstructures 2 in a planar hexagonal intersecting manner, the prism plate has a smaller secondary light spot.

[0025] In this embodiment, a prism plate with uniform light emission is provided, wherein the radius of the hemispherical microstructure 2 is greater than 0.3 mm and less than 0.75 mm.

[0026] Specifically, when the radius of the hemispherical microstructure 2 is less than 0.3 mm, due to factors such as mold precision, plastic material characteristics, and plastic processing errors, the light output consistency is poor when the prism plate is used with small-angle reflective elements (reflector 3 or lens 4, etc.), which easily leads to light concentration.

[0027] When the radius of the hemispherical microstructure 2 is greater than or equal to 0.75 mm, bright spots in the shape of intersecting hexagonal arrays will gradually appear around the light spot, and the bright spots become more and more obvious as the radius of the hemispherical microstructure 2 increases.

[0028] Therefore, in this embodiment, by making the radius of the hemispherical microstructure 2 greater than 0.3 mm and less than 0.75 mm, the prism plate can mix more uniform multi-color light and also obtain higher light output.

[0029] In this embodiment, a prism plate with uniform light output is provided, wherein the distance between the centers of two adjacent hemispherical microstructures 2 is greater than 1.3 times the radius of the hemispherical microstructure 2 and less than √3 times the radius of the hemispherical microstructure 2.

[0030] Specifically, in this embodiment, by making the distance between the centers of two adjacent hemispherical microstructures 2 greater than 1.3 times the radius of the hemispherical microstructure 2 and less than the square root of 3 times the radius of the hemispherical microstructure 2, the prism plate can mix more uniform multi-color light and also obtain higher light output.

[0031] In this embodiment, a prism plate with uniform light emission is described, wherein the radius of the hemispherical microstructure 2 is equal to 0.3 mm. Specifically, when the ratio of the distance between the centers of two adjacent hemispherical microstructures 2 to the radius of the hemispherical microstructure 2 is fixed, the light emission efficiency is highest when the radius of the hemispherical microstructure 2 is equal to 0.3 mm.

[0032] In this embodiment, a prism plate with uniform light emission is provided, wherein the distance between the centers of two adjacent hemispherical microstructures 2 is equal to 1.3 times the radius of the hemispherical microstructure 2.

[0033] Specifically, when the radius of the hemispherical microstructure 2 is fixed, the light output efficiency of the prism plate is highest when the distance between the centers of two adjacent hemispherical microstructures 2 is equal to 1.3 times the radius of the hemispherical microstructure 2.

[0034] In this embodiment, a prism plate with uniform light output is provided, wherein the distance between the centers of two adjacent hemispherical microstructures 2 is equal to the square root of 3 times the radius of the hemispherical microstructure 2.

[0035] Specifically, when the radius of the hemispherical microstructure 2 is fixed, the prism plate achieves the best multi-color light mixing effect when the distance between the centers of two adjacent hemispherical microstructures 2 is equal to the square root of 3 times the radius of the hemispherical microstructure 2.

[0036] In this embodiment, a prism plate with uniform light emission is described, wherein a reflector 3 is connected to the other side of the main body 1. Specifically, as shown... Figure 3 As shown, multi-colored light is reflected multiple times through the inner surface of the reflector 3, and the mixed colored light is emitted at an angle smaller than a certain angle to the light-incident side of the prism plate. After being refracted by the prism plate, the mixed colored light is mixed again by the hemispherical microstructure 2 on the light-outceasing side of the prism plate, thus mixing the multi-colored random colored light into uniform colored light.

[0037] In this embodiment, a prism plate with uniform light output is described, wherein a lens 4 is connected to the other side of the body 1. Specifically, as shown... Figure 4 As shown, multi-colored light is refracted and reflected inside lens 4, and the mixed colored light is incident on the light-incident side of the prism plate at an exit angle smaller than a certain angle. After being refracted by the prism plate, the mixed colored light is mixed again by the hemispherical microstructure 2 on the light-outceasing side of the prism plate, thus mixing the multi-colored random colored light into uniform colored light.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
