Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an optical lens microstructure and lighting device. Background Technology

[0002] With the rapid development of intelligent technology, most LED lighting products now have intelligent control functions to meet market demands, including adjusting power, color temperature, and light distribution curves.

[0003] Currently, the common practice for adjusting the light distribution curve is to mechanically replace the lens. This is done by adjusting the relative position of the lens and the LED to adjust the light distribution curve. This mechanical method requires tools to move the parts, which not only increases the difficulty of lamp protection and material costs, but also poses additional uncontrollable risks due to protection failure. Currently, no effective solution has been proposed to address these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0044] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] like Figure 1-7 As shown, this application relates to an optical lens microstructure and an illumination device. Figure 1-3 As shown, the optical lens microstructure includes: a substrate 10; the substrate 10 provides a support platform for the entire microstructure, forming a load-bearing frame; at the same time, it can also achieve good assembly effect between various components.

[0047] A concave cavity 20 is semi-openly disposed within the substrate 10. The concave cavity 20 is disposed inside the substrate 10 to provide embedding space for the subsequent lens array. It has a semi-open structure, which can protect the internal microstructure and facilitate the incident and control of light.

[0048] A plurality of first lenses 30 are arranged in an array at intervals along the length of the substrate 10 on the upper surface of the bottom of the cavity 20; by arranging the first lenses 30 in an orderly array at intervals on the upper surface of the bottom of the cavity 20, basic light focusing or diverging functions can be achieved.

[0049] Several second lenses 40 are respectively disposed between adjacent first lenses 30; they can achieve a good positional fit with the first lenses 30, thereby forming the effect of two optical channels.

[0050] It should be noted that the application of lens 70 in lighting devices includes, but is not limited to, the following aspects: beam control and focusing: by using convex lenses or combinations of lenses, lighting devices can focus the light beam into a smaller angle to achieve a focusing effect.

[0051] Diffusion: By using concave lenses or diffusion lenses, light beams can be diverged at a larger angle, providing uniform illumination.

[0052] Preferably, the material of lens 70 includes, but is not limited to: glass lenses have good optical performance and high temperature resistance, but are heavy and costly, and are suitable for high-end or special lighting applications.

[0053] Plastic lenses are lightweight, low-cost, and easy to process, making them widely used in general lighting fixtures. Examples include PMMA (acrylic) and PC (polycarbonate).

[0054] The first lens 30 and the second lens 40 are alternately arranged in an array to form a double-strip microstructure, giving the optical lens microstructure two micro-optical channels. By alternating the first lens 30 and the second lens 40, two channels with different optical paths are formed.

[0055] Preferably, the lens 70 is integrated with the heat sink.

[0056] As can be seen from the above description, this application achieves the following technical effects:

[0057] In this embodiment, an optimized lens structure is adopted. The first lens 30 and the second lens 40 are alternately arrayed to form a double-strip microstructure, giving the optical lens microstructure two micro-optical channels. This achieves the purpose of forming a double-strip structure, thereby realizing the technical effect of dividing the internal structure of the lens into two micro-optical channels. This solves the problem that the current common practice of adjusting the light distribution curve is to mechanically replace the lens. The light distribution curve is adjusted by changing the relative position of the lens and the LED. This mechanical method requires tools to move the parts, which not only increases the difficulty of lamp protection and material costs, but also poses the technical problem of additional uncontrollable risks due to protection failure.

[0058] Furthermore, the outer edge of the base 10 is provided with a plurality of mounting holes 101, which are located between the base 10 and the cavity 20. This facilitates assembly, ensuring structural stability between components; it also facilitates embedded or panel-mounted installation of modular lighting fixtures.

[0059] Furthermore, the inner wall of the cavity 20 is sloped at least along both sides of the long side of the substrate 10, and the sloped shape 201 extends obliquely outward from the bottom to the top. It can be understood that by adopting the sloped shape 201, it is beneficial for light to be guided along the slope direction after refraction in the lens, thereby reducing light energy loss; at the same time, it can also reduce edge shadows or occlusion effects and improve the overall light emission uniformity.

[0060] Furthermore, the height of the first lens 30 is less than the height of the second lens 40. This allows the channel lens area to form a uniformly divergent light beam, while the narrow-angle lens area forms a concentrated beam; simultaneously, it provides a three-dimensional composite light distribution structure, combining area illumination and point illumination functions; and it helps to construct an asymmetric beam distribution, broadening the application scenarios for lighting products.

[0061] Furthermore, the first lens 30 is a channel lens, which is used to form a uniform longitudinal light band. This ensures uniform light distribution within the illumination area, preventing noticeable light spots or dark areas.

[0062] Furthermore, the second lens 40 is a narrow-angle lens, which is used to confine light within a preset angle range. This allows for precise projection of light onto a specific area, increasing illuminance, reducing ineffective diffusion, and enhancing lighting efficiency.

[0063] like Figure 3 As shown, the channel lens has a first directional arc surface 301 on one side of the incident surface. This allows for effective light guiding, concentrating the light and spreading it longitudinally, thereby reducing the angular error of the incident light and improving the consistency of the emitted light.

[0064] Furthermore, the narrow-angle lens is provided with a second directional arc surface 401 on one side of the incident surface;

[0065] The height of the first directional arc surface 301 is greater than that of the second directional arc surface 401. It can be understood that by employing different curvatures, different incident control mechanisms are formed, helping to accurately construct multiple beam patterns; high curvature is used for diffusion, and low curvature is used for focusing, enhancing the light distribution layering function of the overall lighting system.

[0066] like Figure 1-2 As shown, this application also relates to an illumination device including the aforementioned optical lens microstructure;

[0067] It also includes: a lamp panel 50, which is connected to a plurality of first lenses 30 and a plurality of second lenses 40 respectively, and is located on one side of the incident surface of the first lenses 30 and the second lenses 40; and

[0068] A waterproof component 60 is disposed between the substrate 10 and the lamp panel 50;

[0069] The lamp panel 50 is provided with a plurality of lamp beads 501 arranged in a spaced array, and the plurality of lamp beads 501 are arranged in a sequential array within the first lens 30 and the second lens 40.

[0070] Specifically, by setting a lamp plate 50 on the incident surface of the optical lens microstructure, and sequentially and orderly arranging a plurality of lamp beads 501 on the lamp plate 50, with each lamp bead 501 corresponding to the first lens 30 and the second lens 40 respectively, a complete modular lighting unit can be formed. This also ensures that each type of lens obtains an independent light source, thereby enabling precise control of the light-emitting behavior of each optical unit, avoiding cross-interference between multiple light sources, improving optical cleanliness, and ultimately facilitating dynamic lighting or intelligent zone control. Preferably, the lamp beads 501 are LED lamp beads.

[0071] By employing the waterproof component 60, electronic components can be protected from moisture corrosion, making it suitable for outdoor or high-humidity environments. Preferably, the waterproof component 60 can be a waterproof ring.

[0072] like Figure 4 As shown, it also includes: an adjustment switch, which is electrically connected to the lamp panel 50;

[0073] The lamp panel 50 controls the lamp beads 501 located in the first lens 30 and the second lens 40 to light up or turn off according to the control signal issued by the adjustment switch, so that the smallest optical lens unit has multiple modes of light distribution curves. It is understood that by providing an adjustment switch, a good switching adjustment effect can be achieved, thereby achieving a good circuit control effect and ultimately a precise opening and closing effect. Preferably, the adjustment switch can be a DIP switch, which can achieve convenient DIP control and adjustment.

[0074] like Figure 5-7 As shown, through

[0075] This utility model also has the following beneficial effects:

[0076] 1. This application enables a more convenient and faster optically adjustable function, solving problems such as lens replacement, difficult disassembly and assembly, numerous accessories, and safety hazards.

[0077] 2. This application utilizes two optical structures of lenses and achieves adjustable light pattern through the controller's DIP switch, eliminating the difficulty of repeated disassembly and assembly when replacing lenses, and making installation and maintenance convenient without the need to disassemble the lamp.

[0078] 3. This application uses this lens structure, which reduces the number of parts and lowers manufacturing and assembly costs.

[0079] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
