[0031] The embodiments of the present utility model will be described below according to its overall structure.
[0032] An anti-static structure for an LED lamp bead, as Figures 1 - 4As shown in the figure, it includes a lamp bead 1. The lamp bead 1 includes a base 101, pins 102, and a lamp body 103. Two first side grooves 105 and second side grooves 106 are respectively arranged at the front and rear ends and both sides of the lamp body 103. A protective mechanism 2 is engaged and slidably connected to the outside of the lamp bead 1. The protective mechanism 2 includes an enclosing frame 201. Two sliders 203 are respectively arranged at the front end and the rear end of the inner wall of the enclosing frame 201. The sliders 203 are slidably connected to the first side grooves 105. Spring seats 204 are arranged on both sides of the inner wall of the enclosing frame 201. Spring grooves 205 are opened inside the spring seats 204. Springs 206 are installed inside the spring grooves 205. One side of the springs 206 abuts against limit catch blocks 207. An arc-shaped block 107 is arranged inside the second side groove 106. The arc-shaped block 107 abuts against the limit catch blocks 207. A sealing strip 202 is arranged at the bottom of the enclosing frame 201. By arranging the protective mechanism 2 to be engaged and slidably connected to the lamp bead 1, especially the sliding connection between the enclosing frame 201 and the sliders 203 and the first side grooves 105, the protective mechanism can stably and flexibly cover the lamp bead. The spring seats 204, spring grooves 205, springs 206 and limit catch blocks 207 cooperate with the arc-shaped block 107 inside the second side groove 106 to provide a reliable locking mechanism, ensuring the stable position of the protective mechanism above or below the lamp bead. The sealing strip 202 at the bottom provides additional sealing protection for the pins 102 when the protective mechanism is locked below, effectively preventing the invasion of static electricity and moisture.
[0033] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the limit catch blocks 207 and the arc-shaped block 107 can be used to lock the protective mechanism 2 above or below the lamp body 103. The interaction between the limit catch blocks 207 and the arc-shaped block 107 provides a stable locking mechanism for the protective mechanism 2, enabling it to be firmly fixed above or below the lamp body 103. This setting ensures that the protective mechanism will not accidentally move or fall off when subjected to external interference, thereby improving the anti-static protection ability of the LED lamp bead.
[0034] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, when the protection mechanism 2 locks above the two sides of the lamp body 103, it will not interfere with the soldering of the lamp beads 1. When the protection mechanism 2 locks below the two sides of the lamp body 103, the sealing strip 202 can be attached to the circuit board. After the sealing strip 202 is attached to the circuit board, it can effectively seal the pins 102. When the protection mechanism 2 is locked above the two sides of the lamp body 103, its setting will not interfere with the soldering process of the lamp beads 1, ensuring that the lamp beads can be smoothly installed on the circuit board. When the protection mechanism is locked below the two sides of the lamp body, the sealing strip 202 can be closely attached to the circuit board, effectively sealing the pins 102, preventing static electricity from discharging to the internal circuit of the LED lamp beads through the pins, and improving the electrical performance and stability of the lamp beads.
[0035] Refer to Figure 1 , Figure 4 [[ID=...]] , the first side groove 105 and the slider 203 can promote the stable up and down sliding of the protection mechanism 2. The sliding connection setting of the first side groove 105 and the slider 203 enables the protection mechanism 2 to slide stably up and down along both sides of the lamp bead 1. This setting not only facilitates the installation and disassembly process of the protection mechanism, but also ensures that the protection mechanism can maintain a stable position during the sliding process and will not move accidentally due to external interference.
[0036] Refer to Figure 1 , Figure 2 , two pins 102 are provided at the bottom of the base 101, and the two pins 102 are attached to the circuit board. The two pins 102 provided at the bottom of the base 101 are attached to the circuit board. This setting ensures that the LED lamp beads can be stably and firmly installed on the circuit board and realizes good electrical connection. The attachment of the pins to the circuit board also reduces the instability of electrical contact and improves the working reliability and lifespan of the LED lamp beads.
[0037] Refer to Figure 1 , Figure 2 , a lamp body 103 is provided at the top of the base 101, and a lamp head 104 is provided at the top of the lamp body 103. The lamp body 103 and the lamp head 104 provided at the top of the base 101 constitute the main light-emitting part of the LED lamp beads. This setting enables the LED lamp beads to emit uniform and bright light, meeting the lighting requirements. At the same time, the structural setting of the lamp head and the lamp body also optimizes the light propagation path and improves the light efficiency and light-emitting quality of the LED lamp beads.
[0038] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, the material of the enclosure frame 201 is engineering plastic, and the material of the sealing strip 202 is rubber. The enclosure frame 201 is made of engineering plastic, which has good insulation and corrosion resistance, and can effectively protect the LED lamp beads from the external environment. The sealing strip 202 is made of rubber, which has good elasticity and sealing performance, and can ensure the tight fit between the pin 102 and the circuit board, preventing the intrusion of static electricity and humid air. The selection of these two materials improves the anti-static ability and service life of the LED lamp beads.
[0039] The implementation principle of the present utility model is as follows: First, the enclosure frame 201 of the protection mechanism 2 needs to be aligned with the lamp bead 1, so that the slider 203 is aligned with the first side groove 105. Gently push the protection mechanism 2 to slide it along the first side groove 105 until it completely surrounds the lamp bead 1. After the protection mechanism 2 surrounds the lamp bead 1, slide it to the upper or lower sides of the lamp body 103 as needed. If soldering is required, slide the protection mechanism 2 to the upper sides of the lamp body 103 to ensure that it will not interfere with the soldering process;
[0040] When the protection mechanism 2 slides to the required position, use the elastic force of the spring 206 to firmly abut the limit block 207 against the arc-shaped block 107, which can ensure that the protection mechanism 2 is stably fixed above or below the lamp body 103 and will not move or fall off accidentally due to external interference;
[0041] If the protection mechanism 2 has been locked above the two sides of the lamp body 103, soldering operations can be carried out at this time. After soldering, check the welding quality to ensure that the pin 102 is well connected to the pad on the circuit board. If it is necessary to lock the protection mechanism 2 below the two sides of the lamp body 103, gently push the protection mechanism 2 to slide it down. When the protection mechanism 2 slides to the bottom, the sealing strip 202 will be in close contact with the circuit board, effectively sealing the pin 102, which can prevent the static electricity generated by the humid environment or direct human contact from discharging to the internal circuit of the LED lamp bead patch through the pin 102.
[0042] The parts not involved in the present utility model are the same as or can be implemented by the prior art, and will not be elaborated here.
[0043] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model, and they are not limitations of the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
