Abstract
Description
Technical Field
[0001] This utility model belongs to the field of LED chip technology, and in particular relates to an antistatic structure for LED chips. Background Technology
[0002] The anti-static performance of LED chips mainly depends on the LED chip itself, and has less to do with the packaging material and packaging process. LEDs are more susceptible to electrostatic damage, which is related to the small distance between the two electrodes of the bare LED chip. After LED products are packaged, due to the larger pin spacing, the potential difference is greater during electrostatic charge transfer, making LEDs more prone to electrostatic damage accidents. Normally, LED chips are protected against electrostatic damage by using lead wires and applying anti-static materials. Over time, material detachment and lead wire misalignment can easily occur, thereby reducing the effectiveness of the anti-static structure of the chip. Therefore, an anti-static structure for LED chips is proposed.
[0003] For example, Chinese patent CN205824964U discloses an antistatic LED lamp. The antistatic LED lamp includes a lampshade, a base connected to the bottom of the lampshade, a grounding wire connected to the base, a substrate on the base, an antistatic layer on the substrate, a heat dissipation layer on the antistatic layer, and a lamp board on the heat dissipation layer. Both the heat dissipation layer and the outer surface of the base are coated with antistatic powder. The lamp board has positive and negative leads, and an LED chip group is located above the lamp board. The LED chip groups are connected in series, and the series-connected LED chip group is connected in series with the positive and negative leads. A Zener diode is located at the center of the lamp board, and the Zener diode is connected in series with the positive and negative leads in reverse. The Zener diode is connected to the substrate via a wire below it.
[0004] The existing technical documents have the following problems:
[0005] Existing technologies have several drawbacks. For example, the anti-static properties of conventional LED chips rely on lead wires and the application of anti-static material. Over time, this material can detach and the lead wires can shift, reducing the effectiveness of the anti-static structure. Furthermore, due to the small size of LED chips, damage necessitates replacement of the entire chip, increasing operating costs. Therefore, we propose an anti-static structure for LED chips. Utility Model Content
[0006] The purpose of this invention is to address the aforementioned technical problems by providing an antistatic structure for LED beads, thereby increasing the antistatic capability of the beads using various solid adhesives and enabling easy disassembly and replacement of the beads when they are damaged.
[0007] In view of this, the present invention provides an antistatic structure for LED beads, including a substrate, and further comprising: a plastic reflector cup fixedly mounted on the top of the substrate, the interior of the plastic reflector cup being filled with protective adhesive, a die-bonding adhesive fixedly mounted at the bottom of the interior of the protective adhesive, a damming adhesive fixedly mounted on the top of the die-bonding adhesive, a gold wire being installed through the top of the damming adhesive, a threaded seat fixedly mounted on the top of the plastic reflector cup, a threaded head being installed through the top of the threaded seat, a diffuser shell fixedly mounted on the top of the threaded head, and limiting grooves fixedly provided on both sides inside the diffuser shell, with an mounting plate movably mounted between the limiting grooves.
[0008] Based on the above structure, the combined use of die bond adhesive and damming adhesive reduces the area of the LED lamp exposed to air, thereby effectively reducing static electricity generation and improving antistatic capabilities. The mounting plate can be disassembled by screwing on the threaded head to replace the LED chip, thus reducing the difficulty of replacing the LED chip and the cost of using the LED lamp.
[0009] Preferably, a connecting plate is fixedly installed at one end of the gold wire. The connecting plate is made of copper, which facilitates heat conduction of the gold wire.
[0010] Preferably, a lamp body is installed through the top of the mounting plate to emit light.
[0011] Preferably, a heat-conducting copper pillar is installed through the top of the substrate, and a fixing plate is fixedly installed at the bottom of the substrate, so that the heat-conducting copper pillar can conduct heat to the LED lamp.
[0012] Preferably, a gasket is fixedly installed on the top of the fixing plate, and a screw is installed through the top of the gasket to install the fixing plate.
[0013] Preferably, a pressure-reducing pad is fixedly installed at the bottom of the fixing plate. The pressure-reducing pad is made of rubber and is used to reduce the pressure on the bottom of the fixing plate.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] 1. The antistatic structure of this LED bead involves filling the plastic reflector cup with protective adhesive, then applying die-bonding adhesive through the plastic reflector cup, followed by filling and applying damming adhesive. Gold wires are then installed onto the damming adhesive, and the gold wires are protected by protective adhesive. The gold wires then transmit electrical energy to the LED chip. The combined use of die-bonding adhesive and damming adhesive reduces the area of the LED lamp exposed to air, effectively reducing static electricity generation and enhancing antistatic capabilities.
[0016] 2. The anti-static structure of this LED bead connects to the threaded head via a threaded seat, then installs the diffuser shell via the threaded head, and then sets the limiting groove via the diffuser shell. The limiting groove then limits the installation of the mounting plate. During product assembly, the mounting plate is snapped into the limiting groove, and then connected to the threaded seat via the threaded head, which is then pressed and tightened. The diffuser shell enhances the LED lighting effect. When the LED is damaged, the mounting plate can be disassembled by unscrewing the threaded head to replace the LED, thus reducing the difficulty of replacing the LED and the cost of using the LED.
