Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a light source plate pressing device for an LED lamp. Background Art

[0002] With the rapid development of LED lighting technology, LED lamps have been widely used in various fields. One of the core components of LED lamps is the light source board, which carries the LED chip. Its stability and performance directly affect the lamp's lighting effect, lifespan, and reliability. During the assembly and use of LED lamps, the light source board needs to be firmly pressed into a specific position inside the lamp to ensure good contact with the heat sink, circuit connections, and other components. This effectively dissipates the heat generated by the LED chip during operation, ensures stable current transmission, and improves the overall performance and lifespan of the lamp. Therefore, the light source board clamping device of LED lamps is an indispensable and important component in the production and application of LED lamps.

[0003] In the prior art, the clamping device of the light source board of an LED lamp usually adopts some traditional mechanical structures to realize the clamping function. The pressure plate is directly fixed to the lamp housing or the supporting structure by bolts. When the bolts are tightened, the pressure plate applies pressure to the light source board. The principle is to use the rotation of the thread to generate axial pressure so that the pressure plate presses the light source board tightly. This method has a relatively simple structure and the pressure adjustment is relatively intuitive. The size of the clamping force can be adjusted by controlling the tightening degree of the bolts. However, in actual operation, each time a light source board of different specifications is replaced, it is necessary to manually loosen and tighten the bolts to adjust the position and clamping force of the pressure plate. The operation is relatively cumbersome, and it is difficult to ensure that each adjustment can achieve the best clamping effect.

[0004] The existing LED lamp light source board clamping device has a prominent problem in practical application, namely, the fixed pressing plate is difficult to conveniently clamp light source boards of different specifications. Since different models of LED lamps use light source boards of different sizes and thicknesses, the position and clamping force of the pressing plate of the traditional clamping device are often fixed or require complex manual adjustment. This results in that during the production process, when switching light source boards of different specifications for assembly, the operator needs to spend a lot of time and energy to readjust the clamping device to ensure that the light source board can be properly clamped. Not only does this reduce production efficiency, but improper adjustment can easily lead to uneven clamping force, affecting the performance and life of the light source board. For example, on some lamp production lines, when the specifications of the light source board are frequently changed, the bolt-tightening clamping device needs to be tediously adjusted, or the cam position of the cam-tightening device needs to be adjusted each time. This seriously restricts the smoothness and efficiency of production, increases production costs and operational difficulty. Therefore, there is an urgent need for a clamping device that can adapt to light source boards of different specifications to improve the convenience of production and use. To this end, an LED lamp light source board clamping device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a pressing device for a light source board of an LED lamp, comprising a lamp housing 1. The lamp housing 1 is the main outer shell structure of the lamp and is usually made of high-strength, corrosion-resistant materials, such as aluminum alloy or engineering plastics. Aluminum alloy has good heat dissipation performance and mechanical strength, and can effectively dissipate the heat generated when the lamp is working, while being able to withstand certain external force impacts without being easily deformed; engineering plastics have the advantages of good insulation, light weight, and low cost, and are suitable for some occasions with high insulation requirements and do not need to withstand excessive external forces. A connecting component is provided on the outer wall of the lamp housing 1, and the connecting component is used to connect the lamp housing 1. A wiring hole 4 is provided inside the lamp housing 1, and a heat dissipation hole 3 is provided inside the lamp housing 1. A light panel 12 is provided inside the lamp housing 1. The light panel 12 is the core light-emitting component of the LED lamp, and is equipped with components such as LED chips. A pressing component is provided inside the lamp housing 1, and the pressing component is used to press the light panel 12;

[0033] The clamping assembly includes a fixed column 9, the top of the fixed column 9 is fixedly connected to the inside of the lamp housing 1, the outer wall of the fixed column 9 is fixedly connected to a limiting ring 8, the outer wall of the fixed column 9 is slidably connected to a lifting plate 6, the outer wall of the lifting plate 6 is slidably connected to a pressure plate 7, the outer wall of the fixed column 9 is sleeved with a spring 11, the top of the spring 11 is fixedly connected to the inner wall of the lamp housing 1, the bottom of the spring 11 is fixedly connected to the top of the lifting plate 6, and an adjustment assembly is provided inside the pressure plate 7, which acts to adjust the pressure plate 7.

[0034] Specifically, first pull the lifting plate 6 downward, at this time the lifting plate 6 will slide downward along the outer wall of the fixed column 9, and the pressure plate 7 will be driven down together by the lifting plate 6, and the spring 11 will be stretched to store elastic potential energy of the spring 11, and then the light plate 12 will be placed at the appropriate position on the top of the pressure plate 7, and then the lifting plate 6 will be released, and the spring 11 will rebound, and its rebound will drive the pressure plate 7 to move upward, thereby adaptively pressing the light plate 12 to ensure that the light plate 12 can be stably in the required position. During the operation of the entire device, the wires are connected through the wiring holes 4 to provide power support for the lamp, ensuring that the light plate 12 can emit light normally, and at the same time, the heat dissipation holes 3 are used to dissipate heat inside in time. The heat generated by the light plate 12 when it is working is dissipated, a good working environment is maintained inside the lamp, and the service life and performance stability of the lamp are improved. The pressing device can automatically adjust according to the different thicknesses, sizes and other specifications of the light plate 12, without the need for manual frequent adjustment of the pressing force or replacement of different pressing components, which greatly improves the versatility and applicability of the device. For example, on an LED lamp production line, the device can effectively press light plates 12 of different batches and models. At the same time, the adaptive pressing of the spring 11 can compensate for these errors well, ensuring that even if the size of the light plate 12 deviates slightly from the design standard, it can be stably pressed, thereby ensuring the production yield and product quality.

[0035] Reference Figure 1 The connecting component includes a fixing frame 2 and a lampshade 5. The inside of the fixing frame 2 is fixedly connected to the outer wall of the lamp housing 1, and the top of the lampshade 5 is slidably connected to the inside of the lamp housing 1.

[0036] Specifically, the mounting bracket 2 provides reliable support and fixation for the lamp housing 1, allowing it to be securely installed in the desired location. The lampshade 5 effectively prevents dust and moisture from entering the interior of the lamp housing 1. In daily life and work environments, there are a large number of dust particles in the air. Without the protection of the lampshade 5, this dust will gradually settle on components such as the light source and circuit board of the lamp, affecting the lamp's luminous efficiency and heat dissipation performance, and shortening the lamp's service life.

[0037] Reference Figure 2 and Figure 3 The component includes a turntable 16, which is usually made of high-strength engineering plastics or metal materials, such as aluminum alloy or polycarbonate. If aluminum alloy is selected, it has good mechanical strength and processing performance, can withstand large torque and friction, and ensure the stability and durability of the turntable 16 during rotation. The surface of the turntable 16 may be specially treated, such as chrome plating or anodizing, to improve its surface hardness and wear resistance, and prevent wear or corrosion during long-term use. The outer wall of the turntable 16 is rotatably connected to the inside of the pressure plate 7, and a card slot 10 is provided inside the lifting plate 6. A limiting slot 19 is provided inside the turntable 16. A knob 20 is fixedly connected to the bottom of the turntable 16. The knob 20 is a component for manually operating the rotation of the turntable 16. The knob 20 is generally made of plastic or rubber material, and its surface may be designed with an anti-slip texture so that the operator can better grip it when rotating to prevent hand slippage. The shape of the knob 20 can be designed according to ergonomics to conform to the operating habits of the fingers and facilitate force. A slide rail 22 is provided inside the pressure plate 7, and the outer wall of the lifting plate 6 is slidably connected to the inside of the slide rail 22. A translation groove 21 is provided inside the pressure plate 7. A card column 13 is slidably connected to the inside of the pressure plate 7, and the outer wall of the card column 13 is slidably connected to the inside of the card slot 10. One end of the card column 13 is fixedly connected to the connecting column 18, and one end of the connecting column 18 is fixedly connected to the sliding column 15. The sliding column 15 is fixedly connected to the moving column 17, and the outer wall of the moving column 17 is slidably connected to the inside of the limiting groove 19. The outer wall of the connecting column 18 is sleeved with a spring 2 14, and one end of the spring 2 14 is fixedly connected to the outer wall of the card column 13, and the other end of the spring 2 14 is fixedly connected to the inner wall of the translation groove 21.

[0038] Specifically, when installing the light plate 12, it is necessary to operate according to the specific size of the light plate 12. First, turn the knob 20. The rotation of the knob 20 will drive the turntable 16 connected thereto to rotate inside the pressure plate 7. As the turntable 16 rotates, the limiting groove 19 opened inside it rotates. The limiting groove 19 will prompt the internal moving column 17 to slide according to its trajectory. The sliding of the moving column 17 will drive the sliding column 15 to move, and the sliding column 15 will drive the connecting column 18 to translate. The translation of the connecting column 18 causes the card column 13 to slide outward from the inside of the card slot 10, compressing the spring 2 14. The spring The spring 14 stores elastic potential energy, which can push the pressure plate 7 at this time, so that the slide rail 22 slides on the outer wall of the lifting plate 6. After sliding to the appropriate position that matches the size of the light board 12, the knob 20 is released, and the spring 14 will rebound quickly, driving the card column 13 to slide back into the card slot 10, so as to fix the position of the pressure plate 7, so that it can accurately correspond to the light board 12 of the required specifications, providing precise adjustment and stable fixation for the installation of the light board 12. In the production and application of LED lamps, the size of the light board 12 is various, and the pressure plate 7 that can be adjusted horizontally can easily adapt to light boards 12 of different lengths and widths. For example, for a small LED light strip, its light board 12 may be only a few centimeters long, while the size of the light board 12 of a large LED panel lamp may reach tens of centimeters. By adjusting the pressure plate 7 horizontally, it can be ensured that no matter what size the light board 12 is, it can be effectively pressed and fixed. There is no need to design and manufacture a specific pressing device for each specification of the light board 12, which greatly reduces the production cost and the complexity of the equipment.

[0039] Working principle: When installing the light plate 12, turn the knob 20 according to the size of the light plate 12, and drive the turntable 16 to rotate inside the pressure plate 7 through the knob 20, and then drive the internal limiting groove 19 to rotate through the turntable 16, and then drive the internal moving column 17 to slide through the limiting groove 19, thereby driving the sliding column 15 to move, and then the sliding column 15 drives the connecting column 18 to translate, and then the connecting column 18 drives the card column 13 to slide from the inside of the card slot 10, and compresses the spring 2 14, thereby pushing the pressure plate 7, so that the sliding The rail 22 slides on the outer wall of the lifting plate 6, and the knob 20 is released after it reaches the appropriate position. The spring 2 14 rebounds and drives the card column 13 to slide into the card slot 10 to fix it, so as to correspond to the required specifications. Then the lifting plate 6 is pulled, and the pressure plate 7 is driven down by the lifting plate 6, and the lifting plate 6 is made to slide on the outer wall of the fixed column 9. At the same time, the spring 11 is stretched by the lifting plate 6, and the light plate 12 is placed on the top of the pressure plate 7. Then the lifting plate 6 is released, and the pressure plate 7 is driven upward by the rebound of the spring 11 to adaptively press the light plate 12.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
