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.

[0023] like Figures 1 to 4 As shown, the present invention provides a composite curved array LED focusing lens, comprising a focusing lens body 1 and a composite curved array lens 2. A plurality of light sources 3 are equidistantly arranged on one side of the inner wall of the focusing lens body 1, and a collimation unit 4 is arranged on the other side of the light sources 3. The outer side of the collimation unit 4 is installed inside the focusing lens body 1, and a Fresnel focusing surface 5 is installed on the other side of the collimation unit 4. The collimation unit 4 and the Fresnel focusing surface 5 are installed on the outer side of the composite curved array lens 2, and a focal plane 6 is arranged on the other side of the Fresnel focusing surface 5. The focal plane 6 is installed inside the focusing lens body 1.

[0024] refer to Figure 2 A microstructured light diffusion layer 7 is provided on the other side of the light source 3 and the inner side of the collimation unit 4. The microstructured light diffusion layer 7 is installed inside the condenser lens body 1.

[0025] As a technical optimization of this utility model, by setting a microstructured light diffusion layer 7 between the light source 3 and the collimation unit 4, the light propagation can be optimized. Its unique microstructure enables the light to be initially and uniformly dispersed before entering the collimation unit 4, avoiding the situation where the light is concentrated and the local energy is too high or too low, further improving the uniformity of light distribution, helping to improve the overall lighting effect, and reducing adverse phenomena such as glare that may be caused by uneven light, thus protecting the user's eyes.

[0026] refer to Figure 4 Each sub-aperture in collimation unit 4 is hexagonal.

[0027] As a technical optimization of this utility model, by setting a collimation unit 4, each sub-aperture in the collimation unit 4 is designed as a hexagon. This unique shape design ensures effective collimation of light, and compared with traditional circular or square apertures, it can be arranged more closely, improving space utilization and making the entire lens structure more compact. Furthermore, according to the characteristics of different light sources 3 and application scenario requirements, the surface parameters of the collimation unit 4 can be flexibly adjusted to ensure good compatibility with various light sources 3, enhancing the applicability of the product under different lighting conditions.

[0028] refer to Figure 2 The Fresnel focusing surface 5 has an aspherical surface shape, and a mounting plate 8 is installed on one side of the light source 3.

[0029] As a technical optimization of this utility model, by setting the Fresnel focusing surface 5 and the mounting plate 8, the aspherical surface of the Fresnel focusing surface 5 can more accurately control the refraction path of light. Compared with the traditional spherical Fresnel focusing surface 5, it can significantly reduce the generation of aberrations and chromatic aberrations. During the light focusing process, it can concentrate more light on the target area on the focal plane 6, improve the utilization efficiency of light, enhance the energy concentration of the light spot, and thus further improve the overall lighting brightness and clarity. The setting of the mounting plate 8 on one side of the light source 3 provides a stable mounting base for the light source 3, ensuring that the position of the light source 3 inside the lens is fixed, and avoiding the displacement of the light source 3 due to vibration or other external forces, which would affect the lighting effect.

[0030] refer to Figure 2 A fixed ring 9 is fixedly connected to the other side of the mounting plate 8. A movable ring 10 is movably connected inside the fixed ring 9. A movable rod 11 is fixedly connected to one side of the movable ring 10. The surface of the movable rod 11 is threadedly connected to one side of the inner wall of the condenser lens body 1.

[0031] As a technical optimization of this utility model, by setting a fixed ring 9, a movable ring 10, and a movable rod 11, when it is necessary to adjust the position of the mounting plate 8 and the light source 3 during use, the movable rod 11 can be rotated. Under the threaded connection of the condenser lens body 1, the movable rod 11 can move to push the movable ring 10. The movement of the movable ring 10 can push the fixed ring 9 to move. The movement of the fixed ring 9 can push and adjust the usage position of the mounting plate 8 and the light source 3. Different usage scenarios and lighting needs have different requirements for the position and angle of the light source 3. Users can accurately adjust the position of the light source 3 to ensure that the light reaches the optimal optical propagation path when passing through optical components such as the collimation unit 4 and the Fresnel condenser surface 5, thereby achieving ideal light spot effect and lighting uniformity, and meeting special needs such as local strong light lighting in fine processing workshops or key lighting in exhibition areas.

[0032] refer to Figure 2 A rotating block 12 is fixedly connected to one side of the movable rod 11, and an anti-slip ring 13 is fixedly connected to the outside of the rotating block 12.

[0033] As a technical optimization of this utility model, by setting a rotating block 12 and an anti-slip ring 13, the rotating block 12 provides the user with a part that is easy to apply force, increasing the contact area and torque arm between the hand and the movable rod 11 during operation. When adjusting the position of the light source 3, the user can more easily and stably hold the rotating block 12 to perform rotation operation, and the anti-slip ring 13 effectively prevents slippage.

[0034] refer to Figure 2 A heat dissipation groove 14 is provided on one side of the condenser lens body 1, and a one-way heat conduction plate 15 is fixedly connected inside the heat dissipation groove 14.

[0035] As a technical optimization of this utility model, by setting up a heat dissipation groove 14 and a one-way heat conduction plate 15, during the lens operation, the heat dissipation groove 14 and the one-way heat conduction plate 15 can promptly conduct the heat generated inside to the outside. The one-way heat conduction plate 15 can effectively control the direction of heat conduction and avoid the reverse heat transfer affecting the performance of the optical components inside the lens.

[0036] refer to Figure 2 A graphene block 16 is fixedly connected to one side of the unidirectional heat conduction plate 15, and a graphene plate 17 is fixedly connected to the other side of the unidirectional heat conduction plate 15.

[0037] As a technical optimization of this utility model, by setting up graphene blocks 16 and graphene plates 17, the graphene blocks 16 on one side and the graphene plates 17 on the other side of the unidirectional heat conduction plate 15 utilize the excellent thermal conductivity of graphene to greatly improve heat dissipation efficiency, ensure that the lens temperature remains within a reasonable range during long-term operation, effectively reduce the impact of temperature on optical performance, ensure stable operation of the equipment, extend service life, reduce problems such as aging and damage of optical components caused by overheating, and improve product reliability.

[0038] The working principle and usage of this utility model are as follows: During use, several light sources 3, evenly spaced on one side of the inner wall of the focusing lens body 1, emit light. The light first reaches the microstructure light diffusion layer 7. The microstructure light diffusion layer 7 utilizes its unique microstructure to initially and uniformly disperse the light, preventing concentration or unevenness in the initial stage. This allows the light to enter the collimating unit 4 in a relatively uniform state. Each sub-aperture in the collimating unit 4 is hexagonal. This structure can adjust the light based on the divergence angle of the light emitted by each sub-light source 3 through its specific surface parameters. The light beams are collimated, making them more parallel and laying a good foundation for the subsequent focusing process. The collimated light then reaches the Fresnel focusing surface 5. Because the Fresnel focusing surface 5 is aspherical, it can efficiently focus and combine the light beams based on the optical characteristics of aspherical surfaces, precisely converging the light onto the focal plane 6. This achieves a compact structure, small size, light weight, and uniform distribution of light spot energy, effectively solving the problem of halo caused by poor light spot cross-cutting and diffusion in existing array LED lighting, thus achieving an ideal lighting effect.

[0039] In summary, this composite curved array LED focusing lens, through the synergistic effect of the composite curved array lens 2, collimation unit 4, and Fresnel focusing surface 5, solves the problems of cross-pollination and diffusion of illumination spots in existing array LED focusing lenses, effectively suppresses the occurrence of halo phenomena, improves light output quality and illumination effect, and enhances the user experience.
