Description

Technical Field

[0001] This application relates to the field of light source refractor technology, specifically to a lens module. Background Technology

[0002] With the rapid development of semiconductor lighting technology, LED lamps have been widely used in indoor and outdoor lighting due to their advantages such as high efficiency, energy saving, and long lifespan. In the design of LED optical systems, the lens module, as a key optical component, directly affects core performance indicators such as luminous efficacy distribution and glare control.

[0003] In existing technologies, to meet the lighting requirements for glare reduction, a structure with an independent reflector cup installed on the outside of the lens body is commonly used to reduce glare by concealing the light source. However, the reflector cup is usually assembled on the lens as a separate component, making the overall thickness of the lens module the sum of the heights of the lens body and the reflector cup, which restricts the design of thinner and lighter lamps. Summary of the Invention

[0013] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the face mask is provided with a light-shielding layer. The face mask can achieve light blocking by setting a light-shielding coating.

[0014] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the lens body includes a plurality of anti-glare cups, and the plurality of anti-glare cups are connected as one unit through the substrate.

[0027] Example 1

[0028] See attached document Figure 1 The disclosed embodiment 1 of this application shows that the lens module of this embodiment includes a lens body 10, the lens body 10 includes an anti-glare cup 11, the bottom of the anti-glare cup 11 is provided with an arc-shaped groove 12 for accommodating an LED lamp 60, the groove wall of the arc-shaped groove 12 constitutes the light-incident surface of the lens body 10, and the inner wall of the anti-glare cup 11 constitutes the light-exit surface of the lens body 10.

[0029] In this embodiment, the light emitted by the LED lamp shines into the anti-glare cup 11, passes through the anti-glare cup 11, and exits through the cup opening. In this application, the structure of the anti-glare cup 11 with a certain depth is directly made on the lens. The anti-glare cup 11 can reduce glare by deeply concealing the light source without the need for a reflector. This can reduce the height of the lamp, save material costs, and does not affect the light efficiency, which is in line with the principle of cost reduction and efficiency improvement.

[0030] Preferably, the groove wall of the arc-shaped groove 12 is provided with a light-mixing microlens structure 20. The light emitted by the LED lamp is mixed by the light-mixing microlens structure 20 and then shines through the anti-glare cup 11 before exiting, which improves the uniformity of the light source emitted by the lens module and helps to reduce light spots. In this embodiment, the light-mixing microlens structure 20 is a Fermat spiral bead surface.

[0031] Preferably, the outer wall of the anti-glare cup 11 is provided with a reflective microstructure 30. Referring to the accompanying drawings, the reflective microstructure 30 includes raised ribs arranged sequentially on the cup wall of the anti-glare cup 11. The light emitted by the LED light hits the cup wall of the anti-glare cup 11 and is reflected by the reflective microstructure 30 into the anti-glare cup 11 before being emitted, thereby improving the light utilization rate.

[0032] Furthermore, the lens body 10 also includes a substrate 13 surrounding the mouth of the anti-glare cup 11. When the light emitted by the LED light shines out of the anti-glare cup 11 and onto the substrate 13, the substrate 13 can also produce a light-emitting effect, improving light utilization and enhancing the aesthetics of the lens.

[0033] The substrate 13 is mounted on the LED light panel by fasteners, and the LED light panel can be provided with one or two LED lights corresponding to each of the arc-shaped grooves 12.

[0034] Based on the above, a microlens structure 40 is provided on the substrate 13 in this embodiment. When the light emitted by the LED lamp shines outside the anti-glare cup 11 and illuminates the microlens structure 40, the substrate 13 produces a sparkling visual effect, thereby further improving the aesthetics of the lens.

[0035] The microlens structure 40 is a microstriped lens structure. The microlens structure 40 can be disposed on both sides or any side of the substrate 13. Referring to the accompanying drawings, in this embodiment, the microlens structure is disposed on the side of the substrate 13 closer to the LED lamp. The microstriped lens can make the emitted light parallel, improving the uniformity of the emitted light from the lens module.

[0036] Preferably, the lens body 10 includes a plurality of anti-glare cups 11, and the plurality of anti-glare cups 11 are connected as one unit through the substrate 13. In this embodiment, the lens body 10 is provided with at least two anti-glare cups 11 to form a linear lens module. In other embodiments, they can be freely combined and spliced ​​to form lens modules of different lengths and shapes.

[0037] Example 2

[0038] Based on the lens module proposed in Embodiment 1, this embodiment also designs a mask 50 mounted on the substrate 13. The mask 50 is provided with a cup-shaped through hole that matches the anti-glare cup 11, and the wall of the cup-shaped through hole matches the cup wall of the anti-glare cup 11.

[0039] See attached document Figure 5-6 As shown, the mask 50 is added to the substrate 13. The cup-shaped through hole of the mask 50 further conceals the light source, thereby further reducing the glare value and improving the anti-glare effect. Compared with the prior art, the height of the reflector cup can be reduced, which is beneficial to compressing the height of the lamp while improving the anti-glare effect.

[0040] Referring to the accompanying drawings, the mask 50 is provided with a locking arm, and the base plate 13 is provided with a locking hole. The locking arm extends into the locking hole to realize the locking of the mask 50 and the lens body 10.

[0041] Preferably, the mask 50 is a colorless or colored transparent and light-transmitting mask, a semi-transparent mask, or a light-blocking mask.

[0042] The transparency and color of the mask 50 can be designed according to requirements. For example, the mask 50 can be transparent and colorless, or made of colored transparent material, or the mask 50 can be semi-transparent milky white, or an opaque mask.

[0043] When the mask 50 is an opaque mask, the mask 50 is provided with a light-blocking layer, and the mask 50 can achieve light blocking by setting a light-blocking coating.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
