Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a pentagonal light-mixing pattern optical structure in the field of lighting. 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 commonly uses a limited variety of pattern structures, and products from different manufacturers on the market are highly similar, leading to poor light mixing and color mixing effects, uneven light spot transitions, significant color differences in light spots, 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 provide a pentagonal light mixing pattern optical structure for the lighting field with good light mixing and color mixing effects.

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

[0005] A pentagonal light-mixing pattern optical structure for the field of lighting includes an optical component. The surface of the optical component is provided with a plurality of continuous pentagonal light-mixing micro-protrusions. The surface of the pentagonal light-mixing micro-protrusions is provided with an outwardly protruding arc surface. Four of the pentagonal light-mixing micro-protrusions are combined to form a hexagonal light-mixing micro-protrusion group.

[0006] Furthermore, the hexagonal uniform light micro-protrusions are arranged laterally.

[0007] Furthermore, the hexagonal uniform light micro-protrusions are arranged vertically.

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

[0009] Furthermore, the optical accessory 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.

[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.

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

[0012] Compared to existing technologies, this invention features multiple continuous pentagonal uniform light micro-protrusions on the surface of the optical components. Each pentagonal uniform light micro-protrusion has an outwardly protruding arc surface. Four pentagonal uniform light micro-protrusions are combined to form a hexagonal uniform light micro-protrusion group. Each pentagonal uniform light micro-protrusion has a curved arc surface. The resulting light mixing structure has an uneven surface with uniform, regular, and continuous patterns. This allows the optical 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 of the optical components for the lamp, uniform light spot transition, small light spot color difference, and a better user experience.

[0022] 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.

[0023] like Figures 1 to 7 The present invention discloses a pentagonal light-mixing pattern optical structure for lighting applications, comprising an optical component 1. The surface of the optical component 1 is provided with multiple continuous pentagonal uniform light-mixing micro-protrusions 2. Each pentagonal uniform light-mixing micro-protrusion 2 has an outwardly protruding arc surface 3. Four pentagonal uniform light-mixing micro-protrusions 2 are combined to form a hexagonal uniform light-mixing micro-protrusion group 4. The surface of the optical component 1 is provided with multiple continuous pentagonal uniform light-mixing micro-protrusions 2, each with an outwardly protruding arc surface 3. Four pentagonal uniform light-mixing micro-protrusions 2 are combined to form a hexagonal uniform light-mixing micro-protrusion group 4. Each pentagonal uniform light-mixing micro-protrusion 2 has a curved arc surface 3. The resulting light-mixing structure has an uneven surface with a uniform, regular, and continuous pattern. This allows for changes in the direction of the light path, achieving uniform light mixing and color mixing of the light spot. This results in good light mixing and color mixing effect for the lamp, uniform light spot transition, small color difference in the light spot, and a good user experience.

[0024] As one specific implementation method, the hexagonal uniform light micro-protrusion group 4 is arranged in a horizontal direction.

[0025] As another specific implementation, the hexagonal uniform light micro-protrusion group 4 is arranged vertically.

[0026] In one specific implementation, optical component 1 is a light mixer. The light mixer's incident or emitting surface has pentagonal light-uniforming micro-protrusions 2. The light mixer is generally a thin lens of uniform thickness, mainly consisting of three surfaces: the light-incident surface, the light-emitting surface, and the sidewall surface. Both the light-incident and light-emitting surfaces are planar. The pentagonal light-uniforming micro-protrusions 2 are typically designed on either the light-incident or light-emitting surface, or simultaneously on both surfaces.

[0027] In another specific implementation, the optical component 1 is a light mixing mask. The light mixing mask's entrance or exit surface has a pentagonal light-uniforming micro-protrusion 2. The light mixing mask is generally a lens with uniform wall thickness, mainly consisting of three surfaces: the light mixing mask's entrance surface, the light mixing mask's exit surface, and the non-optical surface of the light mixing mask platform. The light mixing mask's entrance and exit surfaces are generally curved surfaces. The pentagonal light-uniforming micro-protrusion 2 is usually designed on either the light mixing mask's entrance or exit surface, or simultaneously on both surfaces.

[0028] In another specific implementation, optical component 1 is a TIR lens. The top surface of the TIR lens's entrance aperture, the bottom surface of the TIR lens's exit aperture, or the TIR lens's exit surface is provided with a pentagonal light-uniforming micro-protrusion 2. The TIR lens typically uses a light-mixing pattern on three surfaces where the pentagonal light-uniforming micro-protrusion 2 is applied: the top surface of the TIR lens's entrance aperture, the top surface of the TIR lens's exit aperture, and the TIR lens's exit surface. The pentagonal light-uniforming micro-protrusion 2 is usually designed on any one of these three surfaces, or simultaneously on two or even all three surfaces.

[0029] Optical component 1 is an optical lens. The optical lens has a pentagonal uniform light-distributing micro-protrusion 2 on its light-incident or light-exit surface. Optical lenses are generally lenses with unequal wall thicknesses (depending on the difference in wall thickness distribution, this type of lens can be called a convex lens or a concave lens), and mainly consist of three surfaces: the light-incident surface, the light-exit surface, and the non-optical platform surface. The light-incident and light-exit surfaces can be either flat, concave, or convex. The pentagonal uniform light-distributing micro-protrusion 2 is usually designed on either the light-incident or light-exit surface of the optical lens, or simultaneously on both surfaces.

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.
