Description
Technical Field
[0001] This utility model belongs to the field of lighting technology, specifically relating to a diffuser that allows for quick replacement of light sources. Background Technology
[0002] Advertising light boxes are a common advertising decoration structure, which includes a light source and an advertising light cover. During assembly, the light source is fixed on the top of the advertising light cover, and the light from the light source shines outward through the advertising light cover. Although it can meet the general usage needs, in actual application, due to the structural limitations of the advertising light cover, it is not conducive to the quick replacement and maintenance of the light source, thus limiting the convenience of use. Summary of the Invention
[0003] The purpose of this invention is to provide a diffuser with a reasonable structure and convenient use, allowing for quick replacement of the light source.
[0004] The technical solution to achieve the purpose of this utility model is a diffuser cover that can quickly replace the light source, which is connected to the light source and includes a hollow spherical cover body. The top of the hollow spherical cover body is integrally bent downward with an upper recessed plate, and the bottom of the hollow spherical cover body is integrally bent upward with a lower recessed plate. A circular mounting hole is provided in the middle of the upper recessed plate; The top surface of the upper recessed plate is fixed with an internally threaded retaining ring by screws, and the outer wall of the light source is provided with an external thread in the middle. The light source is threadedly connected to and positioned on the internal thread retaining ring.
[0005] A further preferred embodiment is that the recessed plate has a light-transmitting hole in the middle.
[0006] A further preferred embodiment is that the hollow spherical cover is a rotomolded, light-transmitting plastic cover.
[0007] A further preferred embodiment is that a lightbox pattern layer is affixed to the outer wall of the hollow spherical cover.
[0008] A further preferred embodiment is that the diameter of the upper recessed plate is larger than the diameter of the light source.
[0009] A further preferred embodiment is that the internal thread retaining ring is a hardware retaining ring.
[0010] This utility model has positive effects: The structure of this utility model is reasonable. It has an upper recessed plate at the top and a lower recessed plate at the bottom of the hollow spherical cover. An internal threaded fixing ring is fixed on the upper recessed plate, which can quickly connect the light source to the internal threaded fixing ring. This facilitates the quick disassembly, replacement and maintenance of the light source, making it more convenient to use. In addition, the light from the light source shines outward through the hollow spherical cover, which helps to improve the effectiveness of advertising lighting and has strong applicability. Attached Figure Description
[0011] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings, wherein: Figure 1 This is a cross-sectional structural diagram of the present invention; Figure 2 This is a top view of the structure of this utility model; Figure 3 This is a schematic diagram of the structure of this utility model when combined with a light source; Figure 4 This is a schematic diagram showing the disassembled structure of the present invention and the light source; Figure 5 This is a schematic diagram of the light source and the present invention.
[0012] Reference numerals: 1. Light source; 2. Hollow spherical cover; 3. Upper recessed plate; 4. Lower recessed plate; 5. Circular mounting hole; 6. Internally threaded retaining ring. Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example
[0014] See Figures 1 to 5 As shown, a diffuser with a quickly replaceable light source, connected to a light source 1, includes a hollow spherical cover 2. The top of the hollow spherical cover has an integrally downward-bent upper recessed plate 3, and the bottom of the hollow spherical cover has an integrally upward-bent lower recessed plate 4. A circular mounting hole 5 is provided in the middle of the upper recessed plate. In this embodiment, the hollow spherical cover is a rotomolded, light-transmitting plastic cover. The diameter of the upper recessed plate is larger than the diameter of the light source. The hollow spherical cover allows light to pass through and illuminate the light source.
[0015] In practical applications, the top surface of the upper recessed plate is fixed with an internally threaded retaining ring 6 by screws. This internally threaded retaining ring is a hardware retaining ring. An external thread is provided in the middle of the outer wall of the light source; during assembly, the light source is threadedly connected to and positioned on the internally threaded retaining ring. This structure improves the ease and effectiveness of light source assembly, facilitates disassembly, replacement, and maintenance, and allows the internally threaded retaining ring to be installed on the lower recessed plate as needed, enabling precise positioning of the light source and expanding its applicability.
[0016] Furthermore, in this embodiment, a light-transmitting hole is provided in the center of the recessed plate. A lightbox pattern layer is attached to the outer wall of the hollow spherical cover. This enhances the decorative effect and has strong applicability.
[0017] This utility model has positive effects: The structure of this utility model is reasonable. It has an upper recessed plate at the top and a lower recessed plate at the bottom of the hollow spherical cover. An internal threaded fixing ring is fixed on the upper recessed plate, which can quickly connect the light source to the internal threaded fixing ring. This facilitates the quick disassembly, replacement and maintenance of the light source, making it more convenient to use. In addition, the light from the light source shines outward through the hollow spherical cover, which helps to improve the effectiveness of advertising lighting and has strong applicability.
[0018] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
