[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the mini anti-glare lens module of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0014] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "center", "longitudinal", "lateral", "up", "down", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0015] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.
[0016] See also Figure 1 to Figure 2 The mini anti-glare lens module of the embodiment of the utility model is characterized by comprising an anti-glare bracket 1, an anti-glare cover plate 2 and a lens 3, wherein the lens 3 is arranged in the anti-glare bracket 1, the anti-glare cover plate 2 is covered on the lens 3, the anti-glare bracket 1 is provided with a light transmission hole 11, the anti-glare cover plate 2 is provided with a filter hole, the filter hole is provided with a filter lens 21, the bottom convex surface of the lens 3 forms a light incident surface 31, the curved surface of the side surface of the lens 3 forms a reflective surface 32, the top concave surface of the lens 3 forms a light emitting surface 33, and the reflective surface 32 faces the two sides of the anti-glare bracket 1.
[0017] In the above embodiment, the mini anti-glare lens 3 module of the utility model has a compact structural design and clear functions. The anti-glare bracket 1 serves as the main frame, and the lens 3 is placed inside to ensure the stability of the structure. The anti-glare cover plate 2 is tightly fixed on the lens 3, which not only fixes the position of the lens 3, but also covers the non-optical mirror part of the lens 3, effectively preventing the spill light generated by the non-optical surface and improving the optical performance. The bottom convex surface of the lens 3 is designed as the light incident surface 31, which directly receives and guides the light source into the module. After the light source enters, a part of the light is directly emitted through the concave light emitting surface 33 at the top of the lens 3 to achieve basic lighting. The other part of the light is irradiated onto the curved reflective surface 32 on the side of the lens 3. The reflective surface 32 faces the two sides of the anti-glare bracket 1. Through the angle and curvature, the light is internally reflected and then emitted through the light emitting surface 33, which increases the diffusion range and uniformity of the light. Stray light may be generated during the reflection process. Through the design of the reflection surface 32 facing the two sides of the anti-glare bracket 1, part of the stray light will be partially blocked on both sides of the anti-glare bracket 1, thereby significantly reducing the emission of stray light and improving the overall lighting effect and visual comfort.
[0018] Please refer to Figure 1 to Figure 2 In another embodiment, the light incident surface 31 includes a side light incident surface 311 and a front light incident surface 312 , and the angle between the front light incident surface 312 and the side light incident surface 311 is 75°.
[0019] In the above embodiment, the front light incident surface 312 directly faces the main light source, and the side light incident surface 311 provides an additional light entrance. The 75° angle design optimizes the angle range of light incidence, which not only ensures efficient light collection, but also avoids light scattering or loss caused by excessive angles, thereby improving light utilization and uniformity of light output.
[0020] Please refer to Figure 1 to Figure 2 In another embodiment, the diameter of the lens 3 is 5 mm.
[0021] In the above embodiment, the small diameter design reduces the path length of the light when passing through the lens 3, so that the light can be transmitted more directly and efficiently without the need for a large cross-beam method. This change allows the design of a more flexible light output angle, breaking through the light output angle of less than 50 degrees that is difficult to achieve due to the size limitation of the traditional lens 3.
[0022] Please refer to Figure 1 to Figure 2 In another embodiment, the diameter of the filter hole is 5.5 mm.
[0023] In the above embodiment, the diameter of the filter hole is set to 5.5 mm, based on the matching of the 5 mm diameter of the lens 3. The design of the filter hole slightly larger than the diameter of the lens 3 ensures that the lens 3 can be completely placed in the hole without obstruction, while providing enough space for the filter lens 21 to be installed and fixed.
[0024] Please refer to Figure 1 to Figure 2 In another embodiment, the diameter of the light-transmitting hole 11 is 6.5 mm.
[0025] In the above embodiment, the diameter of the light-transmitting hole of 6.5 mm is larger than the diameter of the lens 3 of 5 mm, which provides sufficient space for the installation and positioning of the lens 3, ensuring that the lens 3 can be firmly placed in the anti-glare bracket 1 without being squeezed. At the same time, this size also ensures that light can pass through the lens 3 smoothly, reducing light loss or light spot deformation caused by too small an aperture.
[0026] Please refer to Figure 1 to Figure 2 In another embodiment, the vertical distance between the surface of the anti-glare cover plate 2 and the light-transmitting hole 11 is 3 mm.
[0027] In the above embodiment, the 3 mm gap allows the light to pass through the lens 3, be filtered, and then pass smoothly through the light transmission hole 11, so as to achieve effective light emission. This distance ensures that the anti-glare cover plate 2 will not be close to the edge of the light transmission hole 11, thereby avoiding direct blocking of the emitted light or unnecessary reflection, and reducing glare.
[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
