Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a pentagonal + hexagonal mixed light pattern optical structure and corresponding optical accessories. Background Technology

[0002] Currently, in various lighting fields, to improve the uniformity of various light spots, optical components of luminaires are generally designed with light mixing structures. Common light mixing methods are mainly divided into two types: disordered light mixing and ordered light mixing. Disordered light mixing typically involves methods such as texturing, sandblasting, or adding diffusing materials to make transparent materials appear foggy. Ordered light mixing generally involves creating light mixing patterns on the optical components. Because disordered light mixing results in significant luminous flux loss, a generally poor appearance, and poor consistency between the actual sample effect and the design effect, ordered light mixing is commonly used for optical components. However, the existing ordered light mixing patterns are limited in variety, and products from different manufacturers on the market are highly similar, leading to poor light spot mixing and color mixing effects, uneven light spot transitions, significant color differences, and unsatisfactory user experience. Therefore, to avoid the shortcomings of existing technologies, it is necessary to improve them. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and to provide a pentagonal + hexagonal light mixing pattern optical structure and corresponding optical accessories with good light mixing and color mixing effect.

[0004] This utility model is achieved through the following technical solution:

[0005] A pentagonal + hexagonal light-mixing pattern optical structure and corresponding optical accessories are disclosed. The optical accessories include multiple pentagonal uniform light micro-protrusions and multiple hexagonal uniform light micro-protrusions on their surface. Three of the pentagonal uniform light micro-protrusions are arranged in a circular array to form a hexagonal uniform light micro-protrusion group. Six hexagonal uniform light micro-protrusion groups are surrounded by the outer side of the hexagonal uniform light micro-protrusions, and twelve pentagonal uniform light micro-protrusions are surrounded by the outer side of the hexagonal uniform light micro-protrusions.

[0006] Furthermore, both the pentagonal uniform light micro-protrusion and the hexagonal uniform light micro-protrusion have outwardly protruding arc surfaces.

[0007] Furthermore, the hexagonal uniform light micro-protrusion is a regular hexagonal uniform light micro-protrusion.

[0008] Furthermore, the optical component is a light mixing sheet, and the light-incident surface or the light-outcident surface of the light mixing sheet is provided with the pentagonal light-uniforming micro-protrusion and the hexagonal light-uniforming micro-protrusion.

[0009] Furthermore, the optical component is a light mixing mask, and the light-incident surface or the light-exit surface of the light mixing mask is provided with the pentagonal light-uniforming micro-protrusion and the hexagonal light-uniforming micro-protrusion.

[0010] Furthermore, the optical component is a TIR lens, and the top surface of the TIR lens entrance aperture, the bottom surface of the TIR lens exit aperture, or the TIR lens exit surface is provided with the pentagonal uniform light micro-protrusion and the hexagonal uniform light micro-protrusion.

[0011] Furthermore, the optical component is an optical lens, and the optical lens has the pentagonal uniform light micro-protrusion and the hexagonal uniform light micro-protrusion on the optical lens incident surface or the optical lens exit surface.

[0012] Compared to existing technologies, this invention features multiple pentagonal and hexagonal uniform light micro-protrusions on the surface of the optical components. Three pentagonal uniform light micro-protrusions are arranged in a circular array to form a hexagonal uniform light micro-protrusion group. Six hexagonal uniform light micro-protrusion groups are enclosed on the outer side of the hexagonal uniform light micro-protrusions, and twelve pentagonal uniform light micro-protrusions are enclosed on the outer side of the hexagonal uniform light micro-protrusions. The resulting light mixing structure has an uneven surface with uniformly and regularly arranged patterns. This allows the light path direction to be changed, achieving uniform light mixing and color mixing of the light spot. This results in better light mixing and color mixing effects for the lamp, more uniform light spot transition, less color difference in the light spot, and a better user experience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 The present invention discloses a pentagonal + hexagonal light mixing pattern optical structure and corresponding optical accessories, including an optical accessory 1. The surface of the optical accessory 1 is provided with multiple pentagonal uniform light micro-protrusions 2 and multiple hexagonal uniform light micro-protrusions 3. Three pentagonal uniform light micro-protrusions 2 are arranged in a circular array to form a hexagonal uniform light micro-protrusion group 4. Six hexagonal uniform light micro-protrusion groups 4 are surrounded by the outer side of the hexagonal uniform light micro-protrusions 3. Twelve pentagonal uniform light micro-protrusions 2 are surrounded by the outer side of the hexagonal uniform light micro-protrusions 3. The optical component 1 has multiple pentagonal uniform light micro-protrusions 2 and multiple hexagonal uniform light micro-protrusions 3 on its surface. Three pentagonal uniform light micro-protrusions 2 are arranged in a circular array to form a hexagonal uniform light micro-protrusion group 4. Six hexagonal uniform light micro-protrusion groups 4 are surrounded by the outer side of the hexagonal uniform light micro-protrusions 3, and twelve pentagonal uniform light micro-protrusions 2 are surrounded by the outer side of the hexagonal uniform light micro-protrusions 3. The resulting light mixing structure has an uneven surface with a uniform and regular pattern, which can change the direction of the light path and achieve uniform light mixing and color mixing of the light spot. This makes the optical component have a good light mixing and color mixing effect on the lamp, with uniform light spot transition, small light spot color difference, and good user experience.

[0023] Both the pentagonal uniform light micro-protrusion 2 and the hexagonal uniform light micro-protrusion 3 have outwardly protruding arc surfaces 5. Each pentagonal uniform light micro-protrusion 2 and each hexagonal uniform light micro-protrusion 3 has a curved arc surface 5. The surface pattern of the light mixing structure is evenly and regularly arranged, which realizes uniform light mixing and color mixing of the light spot. This makes the optical accessories have a good light mixing and color mixing effect on the lamp, with uniform light spot transition, small light spot color difference, and good user experience.

[0024] As a specific implementation method, the hexagonal uniform light micro-protrusion 3 is a regular hexagonal uniform light micro-protrusion, which makes it easier for the pentagonal uniform light micro-protrusion 2 to be evenly arranged and combined, so as to achieve uniform light mixing and color mixing of the light spot.

[0025] In one specific implementation, optical component 1 is a light mixer. The light mixer's incident surface or exit surface is provided with pentagonal light-uniforming micro-protrusions 2 and hexagonal light-uniforming micro-protrusions 3. The light mixer is generally a thin lens of uniform thickness, mainly consisting of three surfaces: the light-incident surface, the light-exit surface, and the sidewall surface. Both the light-incident and light-exit surfaces are planar. The pentagonal light-uniforming micro-protrusions 2 and 3 are usually designed on either the light-incident or light-exit surface, or simultaneously on both surfaces.

[0026] In another specific implementation, optical component 1 is a light mixing mask. The light mixing mask's light-incident surface or light-exit surface is provided with pentagonal light-uniforming micro-protrusions 2 and hexagonal light-uniforming micro-protrusions 3. The light mixing mask is generally a lens with uniform wall thickness and mainly consists of three surfaces: the light-incident surface, the light-exit surface, and the non-optical surface of the light mixing mask platform. The light-incident surface and the light-exit surface are generally curved surfaces. The pentagonal light-uniforming micro-protrusions 2 and hexagonal light-uniforming micro-protrusions 3 are usually designed on either the light-incident surface or the light-exit surface of the light mixing mask, or simultaneously on both surfaces.

[0027] In another specific implementation, optical component 1 is a TIR lens. The top surface of the TIR lens entrance aperture, the bottom surface of the TIR lens exit aperture, or the TIR lens exit surface is provided with pentagonal uniform light micro-protrusions 2 and hexagonal uniform light micro-protrusions 3. The TIR lens typically uses the following three surfaces for the light mixing pattern created by the pentagonal uniform light micro-protrusions 2 and hexagonal uniform light micro-protrusions 3: the top surface of the TIR lens entrance aperture, the top surface of the TIR lens exit aperture, and the TIR lens exit surface. The pentagonal uniform light micro-protrusions 2 and hexagonal uniform light micro-protrusions 3 are usually designed on any one of these three surfaces, or simultaneously on two or even all three surfaces.

[0028] In another specific implementation, optical component 1 is an optical lens. The optical lens has a pentagonal uniform light micro-protrusion 2 and a hexagonal uniform light micro-protrusion 3 on its light-incident or light-exit surface. The optical lens is generally a lens with unequal wall thickness (depending on the difference in wall thickness distribution, this type of lens can be called a convex lens or a concave lens), mainly consisting of three surfaces: the light-incident surface, the light-exit surface, and the non-optical surface of the optical lens platform. The light-incident and light-exit surfaces can be any of a plane, a concave surface, or a convex surface. The pentagonal uniform light micro-protrusion 2 and the hexagonal uniform light micro-protrusion 3 are usually designed on either the light-incident or light-exit surface of the optical lens, or simultaneously on both surfaces.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
