Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, specifically to an LED lamp bead with an antistatic structure. Background Technology

[0002] LED beads have a much higher electro-optical conversion efficiency than traditional light sources. At the same brightness, they consume only 1 / 10 of the power of incandescent lamps and 1 / 2 of the power of fluorescent lamps. Under normal use, LED beads can last for more than 50,000 hours, far exceeding the lifespan of incandescent and fluorescent lamps. LED beads do not contain harmful substances such as mercury, and they do not emit ultraviolet or infrared radiation during operation. Their high color rendering and cold light source characteristics result in low heat generation, making them very popular with consumers.

[0003] However, traditional LED chips have the following drawbacks:

[0004] LED chips have poor anti-static capabilities. The instantaneous electric field or current generated during electrostatic discharge will form a high voltage across the PN junction of the LED chip, leading to local melting, leakage, accelerated light decay, or even LED failure. Minor damage may not be immediately apparent, but it will reduce product reliability and increase the risk of subsequent failure. Utility Model Content

[0005] The purpose of this invention is to provide an LED bead with an antistatic structure to solve the problems mentioned in the background art, such as the poor antistatic ability of LED beads themselves, the instantaneous electric field or current generated during electrostatic discharge forming a high voltage across the PN junction of the LED chip, leading to local melting, leakage, accelerated light decay, or even lamp failure. Minor damage may not be immediately apparent, but it will reduce product reliability and increase the risk of subsequent failure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an LED lamp bead with an antistatic structure, comprising a lamp holder, a bulb body slidably connected to the top of the lamp holder, a lamp bead chip fixedly installed on one side of the bottom of the inner wall of the lamp holder, a first ionization static eliminator fixedly installed on the other side of the bottom of the inner wall of the lamp holder, a second ionization static eliminator provided on one side of the lamp holder, a first grounding connector fixedly installed on one side of the bottom of the lamp holder, a power connector fixedly installed on one side of the lamp holder, and a wiring mechanism fixedly installed inside the lamp holder. The wiring mechanism includes a positioning plate and a top plate. Limiting plates are fixedly installed on both sides of the top of the positioning plate. The tops of the opposite sides of the two limiting plates are respectively fixedly connected to the two ends of the top plate. A sliding plate is slidably connected between the two limiting plates, and several locking posts are fixedly installed at the bottom of the sliding plate.

[0007] Preferably, a screw is threadedly connected to the middle of the top plate, and the bottom end of the screw is rotatably connected to the middle of the top of the sliding plate. Several slots are provided in the middle of the top of the positioning plate, and each slot corresponds to a number of locking posts. The bottom end of the positioning plate is fixedly connected to the lamp holder. Return springs are fixedly installed on both sides of the top of the sliding plate, and the top ends of the two return springs are fixedly connected to the side of the top plate facing each other. When the user rotates the screw, the thread on the surface of the screw matches the thread on the inner wall of the top plate, so the screw rotates and translates relative to the top plate. The screw pushes the sliding plate from the top, causing the locking posts to engage in the slots. Every two adjacent locking posts cooperate to position the wires from both sides, arranging the wires in an orderly manner.

[0008] Preferably, the bulb body, the first ionization static eliminator, the second ionization static eliminator, the first grounding connector, and the power connector are all electrically connected to the LED chip. The user connects the LED chip to the power supply through the power connector, and the user grounds the LED chip through the first grounding connector. The first ionization static eliminator directly neutralizes the static electricity inside the LED chip, preventing static electricity from being conducted to the external area through the air. The second ionization static eliminator prevents charge transfer.

[0009] Preferably, a second grounding connector is fixedly installed at the bottom end of both the first ionization static eliminator and the bottom end of the second ionization static eliminator. The installation of the second grounding connector facilitates the grounding connection between the first ionization static eliminator and the second ionization static eliminator.

[0010] Preferably, mounting plates are fixedly installed on the bottom ends of both sides of the lamp holder, and threaded holes are opened at the top of the two mounting plates. The user can screw the screw through the threaded holes to install the mounting plate at the location where the LED lamp bead is used.

[0011] Preferably, the surface of the lamp holder is provided with several grooves. The grooves increase the unevenness of the lamp holder itself, making it easier for users to pick up the LED beads.

[0012] Preferably, two symmetrically arranged telescopic rods are fixedly installed at the bottom of the inner wall of the lamp holder. The movable ends of the two telescopic rods are fixedly connected to the side of the bulb body facing the lamp holder. Two connecting springs are fixedly installed on the lamp holder, each located on one side of a telescopic rod. The top ends of the two connecting springs are fixedly connected to the side of the bulb body facing the lamp holder. A locking screw is threaded to the top end of one side of the lamp holder. The lamp holder is fixedly connected to the bulb body by the locking screw. When the user slides the bulb body along the lamp holder, the bulb body pulls the telescopic rod from one side. The movable end of the telescopic rod slides along the fixed end of the telescopic rod, and the bulb body pulls the connecting spring from one side. The connecting spring is elastic, and its elastic deformation buffers the pulling force. Then, the user tightens the locking screw. The thread on the surface of the locking screw matches the thread on the inner wall of the lamp holder, so the locking screw rotates and translates relative to the lamp holder, fixing the lamp holder and the bulb body together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up a first ionization static eliminator and a second ionization static eliminator, the first ionization static eliminator directly neutralizes the static electricity inside the LED bead, preventing static electricity from being conducted to the external area through the air, while the second ionization static eliminator prevents charge transfer. They provide anti-static protection from both the inner and outer sides of the LED bead, respectively, avoiding minor damage, ensuring product reliability, and extending the lifespan of the LED bead.

A power connector 8 is fixedly installed on one side of the lamp holder 1. A wiring mechanism 5 is fixedly installed inside the lamp holder 1. The wiring mechanism 5 includes a positioning plate 51 and a top plate 53. Limiting plates 52 are fixedly installed on both sides of the top of the positioning plate 51. The tops of the opposite sides of the two limiting plates 52 are fixedly connected to the two ends of the top plate 53, respectively. A sliding plate 56 is slidably connected between the two limiting plates 52. Several locking posts 57 are fixedly installed at the bottom of the sliding plate 56.

[0022] A screw 54 is threadedly connected to the middle of the top plate 53. The bottom end of the screw 54 is rotatably connected to the middle of the top of the sliding plate 56. Several slots 58 are provided in the middle of the top of the positioning plate 51. The slots 58 are respectively set with several locking posts 57. The bottom end of the positioning plate 51 is fixedly connected to the lamp holder 1. Return springs 55 are fixedly installed on both sides of the top of the sliding plate 56. The top ends of the two return springs 55 are fixedly connected to the side of the top plate 53 facing each other. When the user rotates the screw 54, the thread on the surface of the screw 54 matches the thread on the inner wall of the top plate 53. Therefore, the screw 54 rotates and translates relative to the top plate 53. The screw 54 pushes the sliding plate 56 from the top, so that the locking posts 57 are locked into the slots 58. Every two adjacent locking posts 57 cooperate to position the wires from both sides, and arrange the wires in an orderly manner.

[0023] The bulb body 2, the first ionization static eliminator 6, the second ionization static eliminator 12, the first grounding connector 11, and the power connector 8 are all electrically connected to the LED chip 4. The user connects the LED chip to the power supply through the power connector 8, and the user grounds the LED chip through the first grounding connector 11. The first ionization static eliminator 6 directly neutralizes the static electricity inside the LED chip, preventing static electricity from being conducted to the external area through the air. The second ionization static eliminator 12 prevents charge transfer.

[0024] The bottom end of the first ionization static eliminator 6 and the bottom end of the second ionization static eliminator 12 are both fixedly installed with a second grounding connector 10. The installation of the second grounding connector 10 facilitates the grounding connection of the first ionization static eliminator 6 and the second ionization static eliminator 12.

[0025] Mounting plates 9 are fixedly installed on the bottom of both sides of the lamp holder 1. Threaded holes 13 are opened at the top of both mounting plates 9. The user can screw the screw through the threaded holes 13 to install the mounting plate 9 at the location where the LED lamp bead is used.

[0026] The surface of the lamp holder 1 has several grooves 14. The grooves 14 increase the unevenness of the lamp holder 1 itself, making it easier for users to pick up the LED beads.

[0027] Two symmetrically arranged telescopic rods 3 are fixedly installed at the bottom of the inner wall of the lamp holder 1. The movable ends of the two telescopic rods 3 are fixedly connected to the side of the bulb body 2 facing the lamp holder 1. Two connecting springs 7 are fixedly installed on the lamp holder 1, each located on one side of the telescopic rod 3. The tops of the two connecting springs 7 are fixedly connected to the side of the bulb body 2 facing the lamp holder 2. A locking screw 15 is threaded to the top of one side of the lamp holder 1. The lamp holder 1 is fixedly connected to the bulb body 2 through the locking screw 15. When the user slides the bulb body 2 along the lamp holder 1, the bulb body 2 pulls the telescopic rod 3 from one side. The movable end of the telescopic rod 3 slides along the fixed end of the telescopic rod 3, and the bulb body 2 pulls the connecting spring 7 from one side. The connecting spring 7 is elastic and undergoes elastic deformation to buffer the pulling force. Then the user tightens the locking screw 15. The thread on the surface of the locking screw 15 matches the thread on the inner wall of the lamp holder 1, so the locking screw 15 rotates and translates relative to the lamp holder 1, fixing the lamp holder 1 and the bulb body 2 together.

[0028] In this embodiment, during use: the user screws the screw through the threaded hole 13 to install the mounting plate 9 at the LED bead's location. The user rotates the screw 54, and the threads on the surface of the screw 54 match the threads on the inner wall of the top plate 53, causing the screw 54 to rotate and translate relative to the top plate 53. The screw 54 pushes the sliding plate 56 from the top, causing the locking pins 57 to engage in the locking slots 58. Each pair of adjacent locking pins 57 cooperate to position the wires from both sides, arranging the wires in an orderly manner. The user connects the LED bead to the power supply through the power connector 8 and grounds the LED bead through the first grounding connector 11. The user slides the bulb body 2 along the lamp holder 1, and the bulb body 2 pulls the telescopic rod 3 from one side. The movable end of the telescopic rod 3 slides along the fixed end of the telescopic rod 3, and the bulb body 2 pulls the connecting spring 7 from one side. The connecting spring 7 is elastic and undergoes elastic deformation to buffer the pulling force. Then, the user tightens the locking screw 15. The thread on the surface of the locking screw 15 matches the thread on the inner wall of the lamp holder 1, so the locking screw 15 rotates and translates relative to the lamp holder 1, fixing the lamp holder 1 and the bulb body 2 together. The size and specifications of the LED beads are adjusted. The first ionization static eliminator 6 directly neutralizes the static electricity inside the LED beads, preventing static electricity from being conducted to the external area through the air. The second ionization static eliminator 12 prevents charge transfer and ensures the antistatic performance of the LED beads themselves.
