Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a polygonal reflector structure with a rotating curved surface and its array arrangement module structure. Background Technology

[0002] With the development of the lighting industry, competition among lighting products is becoming increasingly fierce. High luminous efficacy and energy saving are common development trends for all lighting fixtures. For indoor lighting, adjustable color temperature has gradually become a basic function. Therefore, indoor lighting fixtures must meet the requirements of high luminous efficacy, energy saving, and adjustable color temperature while maintaining a price advantage. Using inexpensive surface-mount light sources and optimizing the production efficiency of lighting fixtures is an effective way to achieve this. Simultaneously, using optical components arranged in multi-module arrays will significantly improve the installation efficiency of lighting fixtures and effectively reduce costs. Furthermore, each small module can simultaneously hold two surface-mount light sources with different color temperatures, thus improving luminous efficacy, reducing costs, and allowing for adjustable color temperature. However, while existing reflectors can meet the requirements for light spot effect, they cannot simultaneously accommodate optical requirements such as high luminous efficacy and adjustable color temperature, resulting in poor performance and additional costs. 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 prior art and to provide a polygonal reflector structure with a rotating curved surface that has good light spot effect and high light efficiency, as well as its array arrangement module structure.

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

[0005] A polygonal reflector structure with a rotating surface and its array arrangement module structure are disclosed. The reflector module includes a reflector module with a plurality of polygonal reflectors. Each polygonal reflector has an incident surface and an exit surface. Both the incident surface and the exit surface are n-sided polygons, where n ≥ 3. The incident surface has n identical first edges, and the exit surface has n identical second edges. The inner side of the polygonal reflector has a reflective surface, which is formed by connecting n identical rotating surfaces. The first edges and the second edges are respectively located at the incident end and the exit end of the rotating surface, and the first edges and the second edges form an angle less than or equal to 180° / 2n.

[0006] Furthermore, the first edge line is either a straight line or a curve.

[0007] Furthermore, the second sideline is a straight line.

[0008] Furthermore, both the light-incident surface and the light-exit surface are quadrilaterals.

[0009] Furthermore, both the light-incident surface and the light-exit surface are hexagonal.

[0010] Furthermore, the reflector module is rectangular or circular in shape.

[0011] Furthermore, the reflector module is provided with several polygonal reflectors arranged in a rectangular array.

[0012] Furthermore, the reflector module is provided with a plurality of polygonal reflectors arranged in a circular array.

[0013] Furthermore, the reflector module is equipped with a module connection platform.

[0014] Furthermore, all the rotating surfaces are rotated and twisted in a clockwise or counterclockwise direction.

[0015] Compared to existing technologies, this utility model features a reflector module with several polygonal reflectors. The inner side of each polygonal reflector has a reflective surface, which is formed by n identical rotating curved surfaces. The first and second edges are located at the incident and exit ends of the rotating curved surfaces, respectively, forming an angle less than or equal to 180° / 2n. This allows for the installation of multiple patch light sources, thereby achieving higher luminous efficiency. On the one hand, the total area of ​​multiple patch light sources is larger than that of a single light source; on the other hand, the dispersed arrangement of multiple light sources allows for better heat dissipation of the lamp. The reflector module can be used independently or in conjunction with a lens. While ensuring the light spot effect, it can improve luminous efficiency, reduce costs, adjust the color temperature, and achieve more uniform color mixing, resulting in better performance.

[0023] 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.

[0024] like Figures 1 to 5 The present invention discloses a polygonal reflector structure of a rotating surface and its array arrangement module structure, including a reflector module 1. The reflector module 1 is provided with a plurality of polygonal reflectors 2. The polygonal reflectors 2 are provided with an incident surface 3 and an exit surface 4. The incident surface 3 and the exit surface 4 are both n-sided polygons, where n≥3. The incident surface 3 is provided with n identical first side lines 5, and the exit surface 4 is provided with n identical second side lines 6. The inner side of the polygonal reflector 2 is provided with a reflective surface, which is formed by n identical rotating surfaces 7 connected together. The first side line 3 and the second side line 4 are respectively provided at the incident end and the exit end of the rotating surface 7, and the first side line 3 and the second side line 4 form an angle less than or equal to 180° / 2n. This utility model can be equipped with multiple patch light sources to achieve higher light efficiency. On the one hand, the total area of ​​multiple patch light sources is larger than that of a single light source. On the other hand, the multiple light sources are distributed in a dispersed manner, which can better utilize the heat dissipation of the lamp. The reflector module can be used alone or with a lens. While ensuring the light spot effect, it can improve the light efficiency, reduce the cost, adjust the color temperature, mix colors more evenly, and achieve good results.

[0025] In practice, the first sideline 3 is either a straight line or a curve.

[0026] In practice, the second sideline 4 is a straight line.

[0027] In one specific implementation, both the light-incident surface 3 and the light-exit surface 4 are quadrilaterals, forming a quadrilateral reflector.

[0028] As another specific implementation, both the light-incident surface 3 and the light-exit surface 4 are hexagonal, forming a hexagonal reflector.

[0029] In practice, the reflector module 1 is rectangular or circular, which facilitates its installation and makes it highly versatile.

[0030] As one specific implementation, the reflector module 1 is provided with several polygonal reflectors 2 arranged in a rectangular array, which is suitable for the installation of square lamps.

[0031] As another specific implementation, the reflector module 1 is provided with a plurality of polygonal reflectors 2 arranged in a circular array, which is suitable for the installation of circular lamps.

[0032] As another specific implementation, the reflector module 1 is provided with a module connection platform 8, which facilitates the installation of the reflector module 1 on the lamp.

[0033] The rotating surfaces 7 are all rotated and twisted in a clockwise or counterclockwise direction to improve the consistency and uniformity of light reflection, ensure the light spot effect, and enhance the light effect.

[0034] High luminous efficiency and energy saving principle: When the power of the lamps is equal, the larger the area of ​​the light source, the better the heat dissipation, and the less light is lost due to the increased junction temperature. When using a reflector module, since it is composed of multiple small reflectors, it will correspond to multiple surface-mount light sources, thereby achieving higher luminous efficiency. On the one hand, the total area of ​​multiple surface-mount light sources is larger than that of a single COB light source; on the other hand, the multiple light sources are distributed, which can better utilize the heat dissipation of the lamp.

[0035] Color mixing optics principle:

[0036] When two light sources with different color temperatures or two monochromatic light sources with different wavelengths are used simultaneously, the closer the proportions of the luminous flux of the two colors in any area of ​​the light spot formed after the optical components control the light before adding the light mixing structure, the more uniform the color mixing of the light spot will be after adding the light mixing structure, and the less color difference will be.

[0037] According to the principle of edge ray scattering, if two light sources of different colors are not perfectly aligned, a color difference will inevitably appear at the edge of the light spot. Furthermore, the shape and size of the emitting surface of commonly used 2835 and 3030 light sources are not similar to the shape and size of the optical components. Therefore, the distance between the edge of the light source and the edge of the reflector's aperture is not equal, which also leads to inconsistent color differences at different points along the edge of the light spot. Based on the above theory, the structure of a conventional hexagonal reflector means that some areas of the light spot will only contain one color. When a light mixing structure is added, this area will inevitably have a significant color difference from other areas of the light spot. When using a hexagonal reflector with a rotating curved surface, the rotation of the surface enhances its lateral reflectivity, reflecting different colors of light to a farther area. This makes the proportion of different colors of light in each area of ​​the light spot more similar, resulting in more uniform color mixing when a light mixing structure is added.

[0038] 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.
