Description

Technical Field

[0001] This utility model relates to the field of LED modules, and in particular to a through-hole spring contact LED module. Background Technology

[0002] An LED module is a component that integrates multiple LEDs arranged according to specific rules, including LED beads, PCB board, driver circuit, and housing, to achieve a specific light-emitting function. Through-hole spring contact LED modules are highly favored because they are extremely convenient to install and maintain, can be quickly assembled, reduce the difficulty of large-scale production, and allow for easy replacement of faulty beads during later maintenance. In terms of electrical performance, the spring contacts provide stable contact with the LED bead pins, reducing contact resistance, heat generation, and ensuring stable light emission. In addition, through-hole LED beads themselves have obvious heat dissipation advantages, and the gap formed by the spring contacts facilitates air circulation, promoting overall heat dissipation of the module and ensuring the performance and lifespan of LEDs in high-power applications.

[0003] When the through-hole contact LED module is in operation, current flows smoothly from the power supply terminal to the PCB board along the wires. The contacts on the board hold the through-hole LED chip pins, achieving a stable and reliable electrical connection and opening a channel for current to flow to the chip. When current flows into the LED chip, electrons and holes inside the chip begin to recombine. During this process, electrons jump from a high energy level to a low energy level and release excess energy in the form of photons, thus achieving light emission. At the same time, the driver chip in the module precisely controls the magnitude and on / off time of the current through the LED chip according to a pre-set program or external control signals. When the LED module needs to display specific patterns or text, or achieve dynamic effects such as light gradients or flashing, the driver chip will adjust the working state of each LED chip according to the corresponding logic, so that the entire LED module presents the expected light emission effects and meets the diverse application needs.

[0004] In the actual use of through-hole spring contact LED modules, there are significant drawbacks in the assembly process. When assembling the equipment, the top cover and the outer shell need to be fastened together. However, the existing design makes this operation extremely complicated. The structural design of the top cover and the outer shell is unreasonable, the positioning of the fastening parts is not precise enough, and the insertion angle has strict requirements. It often requires repeated attempts and adjustments. Moreover, some fastening parts require the assistance of tools, which increases the difficulty of operation. This series of problems seriously reduces the assembly efficiency and greatly affects the efficiency of through-hole spring contact LED modules in practical applications, limiting their application in large-scale, rapid deployment scenarios. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a direct-insertion spring contact LED module, which aims to improve the problem of requiring complicated operations to fasten the top cover and the outer shell during the equipment process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a direct-insertion spring contact LED module, comprising a housing, a plurality of connecting blocks fixedly connected to the top of the housing, a plurality of fixing components disposed inside each connecting block, a top cover slidably connected inside the housing, a circuit assembly disposed inside the housing, a plurality of light bulbs fixedly connected inside the top cover, a plurality of fastening blocks fixedly connected to the outer wall of the top cover, and a connecting groove opened at the bottom of each fastening block;

[0007] Each of the fixing components includes a fixing pin, a limiting plate, and a spring. The outer wall of each fixing pin is slidably connected to the inside of the connecting block. The inner wall of each limiting plate is fixedly connected to the outer wall of the fixing pin. Each spring is disposed inside the connecting block. One end of each spring is fixedly connected to the inside of the connecting block, and the other end of each spring is fixedly connected to one end of the fixing pin.

[0008] As a further description of the above technical solution:

[0009] The circuit assembly includes a circuit board and multiple connecting posts. The circuit board is slidably connected inside the housing, and the bottom end of each connecting post is fixedly connected to the top of the circuit board.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the outer shell has multiple water inlets and multiple water outlets.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the outer shell has multiple water channels and multiple sliding grooves.

[0014] As a further description of the above technical solution:

[0015] Multiple sealing strips are fixedly connected to the outer wall of the top cover, and multiple water flow channels are opened on the outer wall of the top cover.

[0016] As a further description of the above technical solution:

[0017] The water inlets are arranged in a symmetrical array on the outer wall of the outer casing, and the water outlets are arranged in a symmetrical array on the outer wall of the outer casing.

[0018] As a further description of the above technical solution:

[0019] The water channels are arranged in a circular array inside the outer casing, and the sliding channels are also arranged in a circular array inside the outer casing.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the top cover is first lifted up and its surrounding fastening blocks are aligned with the connecting blocks on the upper part of the outer shell. Then, it is moved downwards so that the connecting groove at the bottom of the fastening block contacts the outer wall of the connecting block and the connecting block slides into the connecting groove, thereby squeezing the fixing pin and causing it to retract into the connecting block. When the connecting block enters the deepest part of the connecting groove, the fixing pin pops out under the action of the spring and is stuck in the deepest part of the connecting groove. This achieves the effect of easily fastening the top cover and the outer shell together during the use of the equipment, avoiding the problem of needing complicated operations to fasten the top cover and the outer shell during the equipment process, thereby improving the efficiency of the direct-insertion spring contact LED module.

[0022] 2. In this utility model, during the process of fastening the top cover and the outer shell, the sealing strips around the top cover simultaneously enter the sliding groove opened in the inner wall of the outer shell, sealing the gap between the outer shell and the top cover. When using this device on a rainy day, rainwater will enter from the inlet, flow through the space formed by the first and second water channels, and flow out from the outlet. This achieves the effect of effectively isolating rainwater from the outside of the device during rainy weather, avoiding the need to cover the device with a waterproof cloth during use, thus improving the practicality of the direct-insertion spring contact LED module.

[0029] 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.

[0030] Reference Figures 1-3 The present invention provides an embodiment of a direct-insertion spring contact LED module, comprising a housing 1, a plurality of connecting blocks 4 fixedly connected to the top of the housing 1 for connecting the housing 1 and the top cover 8 together, a plurality of fixing components provided inside each connecting block 4 for fixing the housing 1 and the top cover 8, a top cover 8 slidably connected inside the housing 1 for sealing the housing 1, a circuit assembly provided inside the housing 1 for providing power to the entire device, a plurality of bulbs 9 fixedly connected inside the top cover 8 for emitting light, a plurality of fastening blocks 10 fixedly connected to the outer wall of the top cover 8 for connecting the housing 1 and the top cover 8 in conjunction with the connecting blocks 4, and a connecting groove 11 provided at the bottom of each fastening block 10 for accommodating the connecting block 4;

[0031] Each fixing component includes a fixing pin 5, a limiting plate 6, and a spring 7. The outer wall of each fixing pin 5 is slidably connected to the inside of the connecting block 4 to fix the outer shell 1 and the top cover 8. The inner wall of each limiting plate 6 is fixedly connected to the outer wall of the fixing pin 5 to limit the range of movement of the fixing pin 5. Each spring 7 is disposed inside the connecting block 4 to provide elastic force to the fixing pin 5. One end of each spring 7 is fixedly connected to the inside of the connecting block 4, and the other end of each spring 7 is fixedly connected to one end of the fixing pin 5. The circuit assembly includes a circuit board 2 and multiple connecting posts 3. The circuit board 2 is slidably connected to the inside of the outer shell 1 to connect the entire device. The bottom end of each connecting post 3 is fixedly connected to the top of the circuit board 2 for connection with the bulb 9.

[0032] Specifically, in actual operation, when it is necessary to fasten the outer shell 1 and the top cover 8 together, the operator must first pick up the top cover 8 and align the fastening blocks 10 around the top cover 8 with the connecting blocks 4 on the top of the outer shell 1. After alignment, the operator moves the top cover 8 vertically downward with both hands, so that the connecting groove 11 at the bottom of the fastening block 10 gradually contacts the outer wall of the connecting block 4. As the top cover 8 moves down, the connecting block 4 slowly slides into the connecting groove 11. At the same time, the connecting block 4 will squeeze the fixing pin 5, causing it to slowly retract into the connecting block 4. When the connecting block 4 successfully enters the deepest part of the connecting groove 11, the fixing pin 5 will quickly pop out under the strong elastic force of the spring 7 and be firmly locked in the deepest part of the connecting groove 11. Thus, the outer shell 1 and the top cover 8 are firmly fixed together.

[0033] Reference Figure 4 The outer wall of the outer shell 1 has multiple water inlets 12 for rainwater to flow in, multiple water outlets 13 for rainwater to flow out, multiple water channels 14 for rainwater to flow out, and multiple sliding grooves 15 for accommodating sealing strips 16. Multiple sealing strips 16 are fixedly connected to the outer wall of the top cover 8 to seal the gap between the outer shell 1 and the top cover 8. Multiple water channels 17 are provided on the outer wall of the top cover 8 for rainwater to flow out. The water inlets 12 are arranged in a symmetrical array on the outer wall of the outer shell 1, the water outlets 13 are arranged in a symmetrical array on the outer wall of the outer shell 1, the water channels 14 are arranged in a ring array inside the outer shell 1, and the sliding grooves 15 are arranged in a ring array inside the outer shell 1.

[0034] Specifically, during the fastening operation of the outer shell 1 and the top cover 8, as the fastening action progresses, the sealing strip 16 embedded around the top cover 8 will simultaneously enter the sliding groove 15 opened on the inner wall of the outer shell 1. The sealing strip 16 is soft and elastic, and during the process of embedding into the sliding groove 15, it tightly fits the groove wall, sealing the gap between the outer shell 1 and the top cover 8. When it rains, rainwater will flow into the equipment in an orderly manner through the water inlet 12 on the top of the equipment. The rainwater will then enter the water passage space formed by the first water channel 14 and the second water channel 17. Under the action of gravity, the rainwater flows from the water inlet 12 to the water outlet 13 along the inclined angle of the first water channel 14 and the second water channel 17, and finally is discharged smoothly from the water outlet 13, ensuring that the normal operation of the equipment is not affected by water accumulation inside.

[0035] Working principle: When using the direct-insertion spring contact LED module, first lift the top cover 8 and align the fastening blocks 10 around it with the connecting block 4 on the top of the outer shell 1. Then move it downward so that the connecting groove 11 at the bottom of the fastening block 10 contacts the outer wall of the connecting block 4 and the connecting block 4 slides into the connecting groove 11, thereby squeezing the fixing pin 5 and causing it to retract into the connecting block 4. When the connecting block 4 enters the deepest part of the connecting groove 11, the fixing pin 5 pops out under the action of the spring 7 and is stuck in the deepest part of the connecting groove 11, thereby fixing the outer shell 1 and the top cover 8. During the fastening process of the outer shell 1 and the top cover 8, the sealing strip 16 around the top cover 8 enters the sliding groove 15 opened in the inner wall of the outer shell 1 at the same time, sealing the gap between the outer shell 1 and the top cover 8. When using this device on a rainy day, rainwater will enter from the inlet 12, flow through the space for water passage formed by the first water channel 14 and the second water channel 17, and flow out from the outlet 13.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
