[0002] A light emitting diode (LED) is a semiconductor device that can directly convert electrical energy into light energy. It has the characteristics of high efficiency, low consumption, environmental protection and long life. The basic structure of a light emitting diode consists of P-type and N-type semiconductors. When current passes through, the two semiconductors contact each other to form a PN junction, generating light radiation. The direct-insert light emitting diode adopts an axial lead structure, which makes the device more stable during installation and improves the reliability and durability of the product.

[0003] Traditional through-hole light-emitting diodes (LEDs) usually have a simple axial lead structure, where one lead is the positive pole and the other is the negative pole. When using this type of LED, you first need to ensure that the positive pole is connected to the positive voltage terminal of the power supply, and the negative pole is connected to the negative voltage terminal or the ground wire. The lead length and diameter of the through-hole LED may vary depending on the manufacturer and specific model, but usually they are installed by fixing the leads to the circuit board (PCB) through holes or pads, and then using welding materials (such as solder) to connect the leads to the solder points on the board.

[0004] The above-mentioned traditional light-emitting diodes have their leads exposed after installation and are easily affected by moisture and humidity. In a humid or underwater environment, moisture can penetrate into the leads and packaging materials, causing short circuits or corrosion, thereby affecting the performance and life of the LED. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a direct-plug light-emitting diode, which aims to improve the traditional light-emitting diode. After installation, the leads will be exposed and easily affected by moisture and humidity. In a humid or underwater environment, moisture can penetrate into the leads and packaging materials, causing short circuits or corrosion, thereby affecting the performance and life of the light-emitting diode.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a plug-in light emitting diode, including an outer shell 1, a mounting base 3 is fixedly connected to the bottom of the outer shell 1, a pin 5 is fixedly connected inside the mounting base 3, a protective component is arranged on the outer wall of the pin 5, a circuit board 4 is arranged on the lower surface of the mounting base 3, the outer wall of the pin 5 runs through the inside of the circuit board 4, a limiting plate 9 is slidably connected to the inner wall of the mounting base 3, a sealing gasket 8 is fixedly connected to the lower surface of the limiting plate 9, the sealing gasket 8 is fitted with the circuit board 4, a telescopic rod 10 is fixedly connected to the upper surface of the limiting plate 9, a spring 11 is sleeved on the outer wall of the telescopic rod 10, one end of the spring 11 is fixedly connected to the inside of the mounting base 3, the other end of the spring 11 is fixedly connected to the upper surface of the limiting plate 9, a water absorbent pad 12 is fixedly connected to the lower surface of the mounting base 3, and the water absorbent pad 12 is fitted with the circuit board 4;

[0025] Specifically, first, the two pins 5 are accurately inserted into the preset mounting holes inside the circuit board 4 to ensure that the pins 5 are aligned and tightly fitted with the mounting holes to ensure a stable connection between the circuit board 4 and the entire device. After the pins 5 are inserted, the sealing pad 8 and the water-absorbing pad 12 can naturally fit on the upper surface of the circuit board 4 to form a preliminary sealing structure. With the support of the circuit board 4, a certain supporting force will be applied to the sealing pad 8, prompting the limit plate 9 to slide inside the mounting base 3. During the sliding process, the limit plate 9 will apply pressure to the spring 11 to shrink the spring 11. The shrinkage of the spring 11 will generate a certain thrust, which will react on the limit plate 9 and the sealing pad 8, thereby fitting more closely to the outer wall of the circuit board 4, which not only enhances the connection stability between the circuit board 4 and the entire device, but also achieves efficient sealing of the circuit board 4 through the water absorption performance of the water-absorbing pad 12.

[0026] Reference Figure 1 and Figure 2 The protective assembly includes a reinforcing sleeve 6 and a sealing base 7. The inner wall of the reinforcing sleeve 6 is fixedly connected to the outer wall of the pin 5. The inner wall of the sealing base 7 is fixedly connected to the outer wall of the pin 5. The bottom of the sealing base 7 is fixedly connected to the top of the reinforcing sleeve 6. The outer wall of the reinforcing sleeve 6 is slidably connected to the inside of the circuit board 4. The sealing base 7 fits the circuit board 4. The top of the pin 5 is fixedly connected with a light emitter 15.

[0027] Specifically, first, the pin 5 that is exposed to the outside and has the risk of bending and breaking is effectively reinforced by the reinforcement sleeve 6, thereby improving the stability and durability of the pin 5. Then, during the installation process, the fit between the sealing base 7 and the circuit board 4 is ensured to be tightly fitted, which not only enhances the stability of the entire device, but also effectively prevents foreign objects from entering the interior of the outer shell 1 during installation.

[0028] Reference Figure 3 and Figure 4 The outer wall of the outer shell 1 is fixedly connected with a reinforcing shell 2, the inner wall of the outer shell 1 is fixedly connected with an aluminum heat dissipation sleeve 13, the aluminum heat dissipation sleeve 13 is arranged on the outer wall of the pin 5, the inner wall of the aluminum heat dissipation sleeve 13 is fixedly connected with a heat dissipation plate 14, the inside of the heat dissipation plate 14 is fixedly connected to the outer wall of the pin 5, the heat dissipation plate 14 is arranged inside the outer shell 1, an aluminum layer 17 is arranged on the lower side of the inner part of the outer shell 1, the inside of the reinforcing shell 2 is arranged with an aluminum layer 17, the outer wall of the outer shell 1 is uniformly coated with an anodic oxidation coating 16, and the inner wall of the outer shell 1 is uniformly coated with an aluminum oxide coating 18;

[0029] Specifically, through the close cooperation between the aluminum heat dissipation sleeve 13 and the heat dissipation plate 14 inside the outer shell 1, the heat generated by the light-emitting diode during operation can be quickly diffused, and the heat can be quickly dispersed and conducted to other parts of the outer shell 1, thereby effectively preventing heat from accumulating around the light-emitting diode. In addition, an aluminum layer 17 is provided inside the outer shell 1 and the reinforcement shell 2 to enhance the overall heat dissipation effect. The aluminum layer 17 not only expands the heat dissipation area, but also can quickly transfer heat to the outside of the outer shell 1 and the reinforcement shell 2, thereby achieving more efficient heat dissipation. The inner wall of the outer shell 1 is also evenly coated with an aluminum oxide coating 18. The aluminum oxide coating 18 has good thermal stability and thermal conductivity, which can further improve the heat dissipation efficiency. At the same time, it can also effectively protect the inner wall of the outer shell 1 to prevent it from being eroded by heat. In addition, the outer wall of the outer shell 1 is evenly coated with an anodized coating 16, which effectively prevents the outer shell 1 from being corroded and oxidized by the outside, thereby extending the service life of the light-emitting diode.

[0030] Working principle: When the plug-in light-emitting diode is needed, first insert the two pins 5 into the preset mounting holes inside the circuit board 4, so that the sealing pad 8 and the water-absorbing pad 12 are attached to the upper surface of the circuit board 4. At this time, the support of the circuit board 4 is increased to apply a supporting force to the sealing pad 8, so that the sealing pad 8 drives the limiting plate 9 to slide inside the mounting base 3, thereby applying pressure to the spring 11 to shrink the spring 11, and then the thrust generated by the shrinkage of the spring 11 pushes the limiting plate 9 and the sealing pad 8 to permanently fit on the outer wall of the circuit board 4, and cooperate with the water-absorbing pad 12 to achieve efficient sealing;

[0031] In addition, the leaking pin 5 is reinforced by the reinforcing sleeve 6 to prevent it from bending and breaking, and then the sealing base 7 is tightly fitted with the circuit board 4 after installation, thereby preventing foreign objects from entering the interior of the outer shell 1 during installation, thereby achieving a protective effect;

[0032] Finally, the heat generated during operation is quickly diffused through the cooperation of the aluminum heat dissipation sleeve 13 and the heat dissipation plate 14 inside the outer shell 1, and then the heat is quickly dissipated by cooperating with the outer shell 1 and the aluminum layer 17 inside the reinforcing shell 2. In this process, the inner wall of the outer shell 1 is evenly coated with an aluminum oxide coating 18 to further improve the heat dissipation effect. At the same time, the outer wall of the outer shell 1 is evenly coated with an anodized coating 16, which can effectively prevent external corrosion and achieve the effect of increasing the life of the light-emitting diode.

[0033] 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 substitutions for some of the technical features therein.
