Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting module and its splicing spotlight cover. Background Technology

[0002] A lampshade, also called a lamp umbrella, is a cover placed over a lamp panel to soften, concentrate, or protect against wind and dust. When light is emitted from the LEDs on the lamp panel and shines onto the lampshade, the surface of the lampshade reflects, refracts, or scatters the light, thus controlling the direction of the light and achieving a focusing effect.

[0003] In existing lighting modules, the lampshades are mostly produced as a single piece. During the manufacturing process, uneven thickness or surface defects can easily occur in different parts of the lampshade, significantly affecting its light-gathering effect and making it inconvenient to transport and store. At the same time, existing lampshades are mostly large covers that enclose multiple LEDs, making light more prone to scattering inside the cover. The scattered light deviates from the intended lighting direction, resulting in a decrease in light-gathering effect.

[0004] Therefore, it is necessary to provide a lighting module with a detachable lampshade that has a good light-focusing effect. Utility Model Content

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] refer to Figure 1 As shown, this utility model provides a modular spotlight cover, which is used to install on a lamp plate with a plurality of LED beads and can be used as a lamp cover for a rectangular lamp, specifically as a lamp cover for a clothes drying rack lighting module. The modular spotlight cover 0 includes a first rectangular light guide plate 2 formed by splicing a plurality of transparent first rectangular plates 1.

[0040] Specifically, refer to Figure 2 and Figure 3 As shown, each of the two opposite end faces of the first transparent rectangular plate 1 is provided with a first positive step interface 3 and a first negative step interface 4 that matches the first positive step interface 3; the first positive step interface 3 of the first transparent rectangular plate 1 is correspondingly connected to the first negative step interface 4 of the adjacent first transparent rectangular plate, so that the upper end face of the first positive step interface 3 and the lower end face of the first negative step interface 4 abut against each other.

[0041] The first positive step interface 3 has a connecting rod 31 on its upper end face, and the first negative step interface 4 has a through hole 41 on its lower end face that matches the connecting rod 31. When the first positive step interface 3 of the first transparent rectangular plate 1 is connected to the first negative step interface 4 of the adjacent first transparent rectangular plate 1, the connecting rod 31 is inserted into the through hole 41 to fix the first transparent rectangular plates 1 together, thereby achieving splicing between the first transparent rectangular plates 1. Two first positive step interfaces 3 are connected, and two second negative step interfaces 122 are connected.

[0042] refer to Figure 1 and Figure 4As shown, by setting up a first transparent rectangular plate 1 with x columns and y rows, and ensuring that adjacent first transparent rectangular plates 1 are connected through their respective first positive step interfaces 3 and the corresponding first negative step interfaces 4, the insertion rod 31 is inserted into the corresponding through hole 41, and the upper end face of the first positive step interface 3 and the lower end face of the first negative step interface 4 abut against each other, thus fixing the first transparent rectangular plates 1 together and completing the splicing of a first rectangular light guide plate 2 of a corresponding size. At this time, the spliced ​​first rectangular light guide plate 2 is complete except for the first positive step interfaces 3 and first negative step interfaces 4 on both end faces along the width direction and the first positive step interfaces 3 and first negative step interfaces 4 on both end faces along the length direction, which are not connected. All other first positive step interfaces 3 and first negative step interfaces 4 are spliced ​​together correspondingly. In this embodiment, x=1, y=8.

[0043] The matching connection between the plug rod 31 of the first positive step interface 3 and the through hole 41 of the first negative step interface 4 allows the first transparent rectangular plate 1 to be spliced ​​with adjacent first transparent rectangular plates 1 to form a first rectangular light guide plate 2. This enables the splicing of rectangular lampshades of different sizes, facilitating flexible adjustment of lampshade dimensions and simplifying disassembly, assembly, storage, and transportation. Simultaneously, it helps avoid malfunctions during the production of large-size lampshades, reduces defects prone to occur in large lampshade production, improves production efficiency, and ensures the stability of the lampshade's focusing effect.

[0044] refer to Figure 2 and Figure 3 As shown, the upper surface of the first transparent rectangular plate 1 is provided with a plurality of transparent covers 5. The transparent covers 5 are integrally formed with the transparent rectangular plate. The upper bottom surface of the transparent cover 5 away from the first transparent rectangular plate 1 is recessed inward to form a light guide groove 51. The bottom surface of the light guide groove 51 protrudes along the side away from the first transparent rectangular plate 1 to form a first arc-shaped protrusion 52. The transparent covers 5 are all fastened to a corresponding LED bead through the light guide groove 51.

[0045] The design of the transparent cover 5 facilitates the guidance and focusing of light. When light is emitted from the LED beads, it is reflected and refracted by the inner wall of the transparent cover 5, thus propagating along a specific direction. The design of the light guide groove 51 and the first arc-shaped protrusion 52 can further adjust the direction of the light, making the light more concentrated on the target area and improving the lighting effect. By having the transparent covers 5 snapped onto the corresponding LED beads one by one, each transparent cover 5 can independently guide the light, and the light from each other will overlap on the first transparent rectangular plate 1, which helps to improve the uniformity of lighting.

[0046] By setting the transparent cover 5, the light guide groove 51 and the first arc-shaped protrusion 52, the scattering of light emitted by the lamp beads can be reduced, the number of light refractions and reflections can be increased, the distribution and softness of light can be optimized, and the light can be guided to the target area more effectively, improving the focusing effect of the lamp cover, and at the same time, it is beneficial to improve the lighting range of the lamp beads.

[0047] In this embodiment, the contact area between the transparent cover 5 and the first transparent rectangular plate 1 is larger than the cross-sectional area of ​​the end of the transparent cover 5 furthest from the first transparent rectangular plate 1, facilitating the dissipation of light to the outside. Furthermore, the transparent cover 5 is arranged in a rectangular array along the upper surface of the first transparent rectangular plate 1, resulting in a more uniform distribution of the propagated light. In this embodiment, the transparent cover is a frustum-shaped cone.

[0048] refer to Figure 4 and Figure 5 As shown, a plurality of first light guide surfaces 6 are spaced apart on the lower end surface of the first transparent rectangular plate 1. The first light guide surface 6 includes a plurality of interconnected second arc-shaped protrusions. The first light guide surface 6 is arranged in a horizontal direction, and the transparent cover 5 is located directly below the first light guide surface 6. The first light guide surface 6 is integrally formed with the first transparent rectangular plate 1.

[0049] The second arc-shaped protrusion can more effectively guide the light emitted from the first transparent rectangular plate 1, causing the light to be reflected and refracted multiple times on the lower end surface of the first transparent rectangular plate 1. This allows the light to be more effectively directed to the target area and evenly distributed inside the lampshade, reducing light loss during propagation and further improving the light-gathering effect of the lampshade.

[0050] The first transparent rectangular plate 1 on both sides of the first light guide surface 6 in the horizontal direction is provided with a second light guide surface 7. The second light guide surface 7 includes a plurality of light guide strips 71 with triangular vertical cross sections connected in sequence along the direction close to any adjacent first light guide surface 6. The second light guide surface 7 is integrally formed with the first transparent rectangular plate 1.

[0051] The second light guide surface 7, which includes several light guide strips 71 with triangular vertical cross sections, is located on both sides of the first light guide surface 6 in the horizontal direction. This allows the light propagating to both sides of the first light guide surface 6 to diffuse during propagation, thereby improving light utilization and further expanding the lighting range, enabling the lighting system to cover a wider area.

[0052] refer to Figure 1 and Figure 2As shown, the lower end face of the first transparent rectangular plate 1 is also provided with several fixing posts 8. The fixing posts 8 are all located directly below the second light guide surface 7. The fixing posts 8 are provided with a screw hole 9 that passes through the fixing post 8 and the second light guide surface 7. A screw (not shown in the figure) passes through the screw hole 9 and is fixedly connected to the threaded groove on the lamp plate 22, thereby fixing the spliced ​​spotlight cover to the lamp plate 22.

[0053] In this embodiment, the first transparent rectangular plate 22, the transparent cover 5, the first light guide surface 6, and the second light guide surface 7 are integrally formed, and the first transparent rectangular plate 22, the transparent cover 5, the first light guide surface 6, and the second light guide surface 7 are all made of transparent acrylic material.

The third rectangular light guide plate 11 includes a plurality of third transparent rectangular plates 13, a fourth positive step interface 131 and a third inverted step interface 132 are respectively provided on one opposite side end face of the third transparent rectangular plate 13, and a fourth inverted step interface 133 is provided on any side end face of the fourth transparent rectangular plate 17 adjacent to the fourth positive step interface 131.

The number of the second transparent rectangular plates 12 and the third transparent rectangular plates 13 is the same as the number of columns y of the first transparent rectangular plates 1 in the first rectangular light guide plate 2. In this embodiment, y = 8.

[0058] The second transparent rectangular plate 12 is connected in sequence through the second positive step interface 121 and the second inverted step interface 122 of another second transparent rectangular plate 12 to form the second rectangular light guide plate 10.

[0060] By splicing the first rectangular light guide plate 2, the second rectangular light guide plate 10, and the third rectangular light guide plate 11, the first inverted step interface 4 or the first positive step interface 3 on both sides of the first rectangular light guide plate 2 along the length direction are correspondingly connected to the third positive step interface 123 and the fourth inverted step interface 133 of the first rectangular light guide plate 2, the second rectangular light guide plate 10, and the spliced ​​lampshade has no interfaces on both sides along the length direction.
