Description

Technical Field

[0001] This utility model relates to the field of optical component technology, specifically to an optical component that uses a microstructure combining rhombuses and parallelograms for reflection. Background Technology

[0002] In the lighting field, the most commonly used optical components are reflectors and lenses. To achieve a more uniform light spot transition, optical components undergo light mixing treatment. Common light mixing methods fall into two main categories: disordered light mixing and ordered light mixing. Disordered light mixing typically involves surface roughening, matte finishing, and internal material fogging. However, these treatments result in significant luminous flux loss, generally poor aesthetics, and inconsistent actual sample performance with the design specifications. Therefore, ordered light mixing is more commonly chosen, manifested as the creation of light mixing microstructures on the optical surfaces of the optical components.

[0003] For reflectors and TIR lenses, both their reflective surfaces and internal total internal reflection surfaces can be microstructured to achieve light mixing. Existing products primarily use non-misaligned quadrilaterals, rhombuses, and hexagons for their microstructures, resulting in very limited variety. This leads to inconsistent light spot mixing and color mixing, uneven light spot transitions, and significant color differences, ultimately failing to guarantee illumination performance and resulting in a poor user experience.

[0004] Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide an optical accessory that uses a combination of rhombus and parallelogram microstructures for reflection, which has a simple structure and good performance.

[0006] This utility model is achieved through the following technical solution:

[0007] An optical accessory using a combination of rhombus and parallelogram microstructures for reflection includes an optical accessory body. The optical accessory body has a reflective surface on its inner or outer side. The reflective surface has a first microstructure and a second microstructure arranged in a curved array. The first microstructure and the second microstructure are interleaved and connected. The first microstructure includes an interleaved first rhombus and a first parallelogram, and the second microstructure includes an interleaved second rhombus and a second parallelogram.

[0008] Furthermore, the first rhombus is exactly the same as the second rhombus, and the first parallelogram is exactly the same as the second parallelogram.

[0009] Furthermore, the area of ​​the first rhombus is approximately 50% of the area of ​​the first parallelogram, and the area of ​​the second rhombus is approximately 50% of the area of ​​the second parallelogram.

[0010] Furthermore, the first rhombus, the first parallelogram, the second rhombus, and the second parallelogram are all formed by a combination of four boundary lines, which are either straight lines or curves.

[0011] Furthermore, both the first and second rhombuses include a first side, a second side, a third side, and a fourth side; both the first and second parallelograms include a fifth side, a sixth side, a seventh side, and an eighth side; the second side completely coincides with the eighth side; the upper right vertex of the first rhombus, the lower right vertex of the first parallelogram, the lower left vertex of the second rhombus, and the upper left vertex of the second parallelogram completely coincide; and the upper left vertex of the second rhombus coincides with the center point of the seventh side of the first parallelogram.

[0012] Furthermore, the reflective surface is composed of multiple rows of rhombuses and multiple rows of parallelograms arranged alternately, with the rhombuses or parallelograms in the same row located at the same horizontal height.

[0013] Furthermore, the reflective surface is formed by multiple equal parts of the first microstructure and the second microstructure arranged in a rotationally symmetrical array, and the arrayed surface exhibits a Fermat spiral distribution.

[0014] Furthermore, the optical component is a reflector cup, and the first microstructure and the second microstructure are disposed on the inner side of the reflector cup.

[0015] Furthermore, the optical component is a lens, and the first microstructure and the second microstructure are located on the outside of the lens.

[0016] Furthermore, the optical accessory is an anti-glare shield, and the first microstructure and the second microstructure are disposed on the inner side of the anti-glare shield.

[0017] Compared to existing technologies, this utility model features a reflective surface with a first microstructure and a second microstructure arranged in a curved array. The first and second microstructures are interconnected and interleaved. The first microstructure includes an interleaved first rhombus and a first parallelogram, and the second microstructure includes an interleaved second rhombus and a second parallelogram. This design simplifies the structure of the reflective surface, resulting in better reflection, light mixing, and color mixing of the light spot.

Detailed Implementation

[0024] 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.

[0025] like Figure 1 Figure 4 The present invention discloses an optical accessory using a combination of rhombus and parallelogram microstructures for reflection. It includes an optical accessory body 1, with a reflective surface on either the inner or outer side of the body 1. The reflective surface has a first microstructure 2 and a second microstructure 3 arranged in a curved array, interleaved and connected. The first microstructure 2 includes an interleaved first rhombus 4 and a first parallelogram 5, and the second microstructure 3 includes an interleaved second rhombus 6 and a second parallelogram 7. The microstructure of the reflective surface of this invention has a simple structure, good reflection effect, good light mixing effect, good light spot mixing and color mixing effect, uniform light spot transition, improved light spot color difference, guaranteed illumination effect, and good user experience.

[0026] The first rhombus 4 and the second rhombus 6 are completely equal, and the first parallelogram 5 and the second parallelogram 7 are completely equal. The reflection effect is good, the light mixing effect is good, and the light spot mixing and color mixing effect is good.

[0027] The area of ​​the first rhombus 4 is approximately 50% of the area of ​​the first parallelogram 5, and the area of ​​the second rhombus 6 is approximately 50% of the area of ​​the second parallelogram 7. This forms a stable and uniform series of rhombuses connected to a stable and uniform series of parallelograms, resulting in good reflection, good light mixing, good light spot color mixing, uniform light spot transition, and improved light spot color difference.

[0028] The first rhombus 4, the first parallelogram 5, the second rhombus 6, and the second parallelogram 7 are all formed by the combination of four boundary lines, which can be straight lines or curves.

[0029] Both the first rhombus 4 and the second rhombus 6 include the first side line 8, the second side line 9, the third side line 10, and the fourth side line 11. Both the first parallelogram 5 and the second parallelogram 6 include the fifth side line 12, the sixth side line 13, the seventh side line 14, and the eighth side line 15. The second side line 9 and the eighth side line 15 completely coincide. The upper right vertex of the first rhombus 4, the lower right vertex of the first parallelogram 5, the lower left vertex of the second rhombus 6, and the upper left vertex of the second parallelogram 7 completely coincide. The upper left vertex of the second rhombus 6 coincides with the center point of the seventh side line 14 of the first parallelogram 5, forming a stable and uniform series of rhombuses and parallelograms. This results in good reflection, good light mixing, good light spot mixing and color mixing, uniform light spot transition, and improved light spot color difference.

[0030] The reflective surface is composed of multiple rows of rhombuses and multiple rows of parallelograms arranged alternately. The rhombuses or parallelograms in the same row are located at the same horizontal height, resulting in good reflection, good light mixing, and good light spot mixing and color mixing.

[0031] The reflective surface is formed by multiple equal parts of the first microstructure 2 and the second microstructure 3 arranged in a rotationally symmetrical array. After arraying, it presents a Fermat spiral distribution, which has good reflection effect, good light mixing effect, and good light spot mixing and color mixing effect.

[0032] In one specific implementation, the optical component is a reflector cup, and the first microstructure 2 and the second microstructure 3 are disposed on the inner side of the reflector cup.

[0033] As another specific implementation, the optical component is a lens, and the first microstructure 2 and the second microstructure 3 are disposed on the outside of the lens.

[0034] As another specific implementation, the optical accessory is an anti-glare shield, with the first microstructure 2 and the second microstructure 3 disposed on the inner side of the anti-glare shield.

[0035] 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.
