Description

Technical Field

[0001] This utility model relates to the field of lighting structure technology, and in particular to a fixing structure for a lighting reflector and a light-transmitting plate. Background Technology

[0002] In outdoor lighting fixtures (such as streetlights, courtyard lights, tunnel lights, floodlights, etc.), the method of fixing the light-transmitting plate, reflector, and lower cover of the fixture directly affects parameters such as light transmittance, angle, and installation efficiency. Currently, the light-transmitting plate is mainly fixed using the following two methods:

[0003] Glue fixing: The light-transmitting plate is glued to the fixing frame of the lower cover of the lamp with glue, and then the reflector is glued to the light-transmitting plate. However, the glue is prone to chemical reaction with the reflector, which promotes the aging and yellowing of the reflector, and eventually makes it brittle and causes it to fall off. The production efficiency is also relatively low, and it is difficult to disassemble and maintain after installation.

[0004] Direct fixation with socket screws (as shown in the picture) Figure 5 As shown): A large number of screws with spacers are set on the edge of the lamp fixing frame to directly fix the reflector and the light-transmitting plate. Due to the limited contact area between the screws with spacers and the reflector and the light-transmitting plate, the light-transmitting plate and the reflector are subjected to uneven force and are prone to warping and deformation. Moreover, the installation of the spacers requires precise alignment, and frequent operation can easily lead to stripping of the threads.

[0005] The above method has the following drawbacks:

[0006] Poor stability: The adhesive dispensing is easily affected by ambient temperature and humidity, and the fixation is unstable, making it prone to loosening due to vibration during transportation;

[0007] Installation is complex: the dispensing method can easily lead to uneven glue application and glue overflow; the installation of the micro screws requires precise alignment and frequent operation, resulting in low efficiency.

[0008] Maintenance difficulties: Once fixed with glue, it is difficult to disassemble without damage, and the fixing method of the micro screw is prone to stripping after repeated operation.

[0009] Therefore, there is an urgent need for a convenient fixing method that can effectively reduce the use of adhesive and micro screws while maintaining parameter consistency, efficient installation, and quick maintenance. Utility Model Content

[0010] The purpose of this utility model is to provide a fixing structure for lamp reflectors and light-transmitting plates to solve the problems of easy aging and detachment of adhesive in the prior art and low installation efficiency.

[0011] To achieve the above objectives, the specific technical solution of the lamp reflector and light-transmitting plate fixing structure of this utility model is as follows:

[0012] A fixing structure for a lamp reflector and a light-transmitting plate includes a lamp upper cover and a lamp lower cover. The lamp lower cover has a fixing frame for placing the light-transmitting plate and the reflector. The reflector is disposed on the upper end of the light-transmitting plate. Fixing posts are spaced apart along the edges of the fixing frame. Each fixing post has a pressure plate extending one end toward the light-emitting surface of the lamp. The pressure plate has a T-shaped cross-section and extends downward at both ends to form vertical positioning parts. The vertical positioning parts are fixed to the fixing posts by bolts, and the lower surface of the pressure plate extension is in close contact with the upper surface of the reflector.

[0013] Furthermore, the fixing frame is rectangular, and two fixing posts and two fixing plates are provided on the edges of the fixing frame corresponding to the pressure plate.

[0014] Furthermore, the fixing post is a boss structure, the height of which is greater than the thickness of the fixing frame, and the top of the fixing post is provided with a groove that matches the shape of the pressing plate positioning part.

[0015] Furthermore, a light source plate is provided at the upper end of the fixed frame, a light guide plate is provided at the upper end of the light source plate, and a reflector is provided at the upper end of the light guide plate. The reflector consists of a horizontal plane portion and an upwardly bent guide portion, wherein the guide portion is a recessed area formed by bending the horizontal plane upwards.

[0016] Furthermore, the end length of the extended portion of the pressing sheet is aligned with the width of the horizontal portion of the fixing frame.

[0017] The lamp reflector and light-transmitting plate fixing structure provided by this utility model has the following advantages:

[0018] 1. Adhesive-free fixing: Avoids adhesive aging problems and extends product life.

[0019] 2. Easy installation: Workers only need to align the pressure plate with the fixing column and tighten the bolts to complete the assembly, which effectively improves the installation efficiency.

[0020] 3. Vibration resistance and stability: The press plate is tightly fitted to the reflector, which can effectively improve the stability of the fixation between the reflector and the light source. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] See Figure 1-5 This utility model provides a fixing structure for a lamp reflector and a light-transmitting plate, suitable for scenarios requiring high stability and easy installation, such as LED panel lights. It mainly includes a lamp upper cover 1, a lamp lower cover 2, a fixing frame 3, a fixing post 5, and a pressure plate 6. The lamp lower cover 2 has a rectangular fixing frame 3 for placing the light-transmitting plate and the reflector 4. The upper end of the fixing frame 3 is provided with a reflector 4, which consists of a horizontal plane portion and an upwardly bent guide portion. The guide portion forms a recessed area to facilitate light reflection. Cylindrical protrusions are evenly distributed along the edge of the fixing frame 3 as fixing posts 5. The height of the circular protrusion-shaped fixing posts 5 is greater than the thickness of the fixing frame 3. The top of the fixing posts 5 is provided with a groove. The cross-section of the pressure plate 6 is T-shaped, including a horizontal extension 62 and a vertical positioning part 61. The lower end of the vertical positioning part 61 forms a U-shaped structure with the opening facing downward, which facilitates the positioning of the fixing posts 5. A groove is opened at the upper end to match the groove of the fixing posts 5, which facilitates the fixing with bolts 7. The lower surface of the horizontal extension 62 of the pressure plate 6 is tightly fitted with the horizontal plane of the reflector 4 and locked by bolts 7.

[0029] In use, first open the upper cover 1 of the lamp. Inside the fixing frame 3 of the lower cover 2, place components such as the light-transmitting plate and reflector. The reflector 4 is fixed at the upper end of the light-transmitting plate. Then, place the pressure plate 6 on the fixing post 5, aligning the vertical positioning part 61 of the pressure plate 6 with the fixing post 5, and aligning the groove of the pressure plate 6 with the groove of the fixing post 5. Tighten the bolts 7 to secure the device. Tighten the extension part 62 of the pressure plate 6 to press down on the reflector 4. This effectively completes the fixing after all the bolts 7 on the fixing post 5 are tightened, effectively reducing the application of adhesive. For maintenance, loosening the screws allows for quick opening and access.

[0030] Preferably, in one embodiment, the fixing frame 3 is rectangular, and two fixing posts 5 are provided on each edge to facilitate the distribution of pressure on the reflector 4 and to form a tight fixation.

[0031] In summary, this application achieves the technical effects of glue-free installation, high stability, and rapid installation through a fixing structure for a lamp reflector and light-transmitting plate. By evenly distributing fixing posts 5 along the edge of the fixing frame 3 on the lower cover 2 of the lamp, and setting pressure plates 6 on the fixing posts 5 and locking them with bolts 7, the lower surface of the horizontal extension 62 of the pressure plate 6 is tightly fitted to the reflector 4, evenly distributing pressure and avoiding the problems of aging or loosening of traditional adhesives. Simultaneously, the precise matching between the groove of the pressure plate 6 and the fixing post 5 allows workers to complete the installation simply by aligning and tightening the bolts 7, effectively improving installation efficiency. Disassembly allows for maintenance by loosening the bolts 7, eliminating the need for destructive operations. Compared to existing technologies, the advantages of this utility model are: a large contact area between the pressure plate 6 and the reflector 4, strong vibration resistance, and effectively improved stability; and the elimination of the adhesive dispensing process, reducing adhesive consumption and effectively improving installation efficiency.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
