Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an LED lamp bead connection structure. Background Technology

[0002] LED beads are semiconductor light-emitting devices that convert electrical energy into light energy. They primarily utilize the properties of semiconductor materials, generating photons through the recombination of electrons and holes to achieve light emission. Compared to traditional light sources, they have higher energy conversion efficiency. Connecting LED beads involves using specific connection methods (such as soldering, plug-in, etc.) to connect the LED beads to wires, circuit boards, and other components, achieving electrical conductivity and ensuring the smooth transmission of electrical energy to the beads.

[0003] The LED bead connection structure is a structure that ensures a stable electrical connection between the LED bead and the circuit. It includes components such as wires and leads to ensure smooth current transmission. It also serves to protect and fix the LED bead, thereby improving its performance and lifespan. In existing technologies, some LED bead connection structures have limited current transmission capacity. If a wire or lead fails, the entire circuit will be interrupted, affecting the normal operation of the LED bead. Therefore, an LED bead connection structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an LED lamp bead connection structure, which aims to improve the problem of limited current transmission capability in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An LED bead connection structure includes a housing, a connecting ring fixedly connected to the bottom of the housing, two leads fixedly connected to the bottom of the connecting ring, a heat shrink tubing fixedly connected to the outer bottom of the leads, two wires fixedly connected inside the heat shrink tubing, the outer top of the wires contacting the outer bottom of the leads, the wires being elongated and made of copper, and the outer top of the wires and the outer bottom of the leads being connected by tin alloy welding.

[0007] As a further description of the above technical solution:

[0008] The connecting ring has a placement groove inside, and a circuit board is fixedly connected to the inner wall of the placement groove. Two leads are fixedly connected to the top of the circuit board, and a light-emitting component is fixedly connected to the top of the leads.

[0009] As a further description of the above technical solution:

[0010] The circuit board is ring-shaped and made of glass fiber epoxy resin.

[0011] As a further description of the above technical solution:

[0012] The heat shrink tubing is in the shape of a long, thin tube, and the material of the heat shrink tubing is a polyolefin material;

[0013] As a further description of the above technical solution:

[0014] The light-emitting component is shaped like a small square chip, and the material of the light-emitting component is gallium nitride;

[0015] As a further description of the above technical solution:

[0016] The second lead is filamentous and made of copper.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, when welding the lead wire and the conductor, the lead wire and the two conductors are wrapped and welded together. The function of the two conductors is to prevent power transmission through the other conductor if one conductor is damaged and cannot be used. The welded part is enclosed by heat shrink tubing. When the heat shrink tubing shrinks due to heat, it can tightly enclose the welded part of the lead wire and the conductor, effectively eliminating gaps and preventing dust, moisture and other impurities from entering the weld point. This achieves the goal of welding two conductors to one lead wire, which can increase the current transmission channel, improve the power supply capacity, ensure a stable and sufficient power supply for LED beads, help maintain brightness and performance, and at the same time enhance the stability and reliability of the connection, reducing contact problems caused by loosening and other factors.

[0024] 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.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of an LED bead connection structure, including a housing 1. The housing 1 provides physical protection for the internal electronic components. A connecting ring 2 is fixedly connected to the bottom of the housing 1. The connecting ring 2 plays a crucial role in connecting the upper and lower parts of the housing. Two leads 3 are fixedly connected to the bottom of the connecting ring 2. The leads 3 are important channels connecting the internal circuit of the LED bead with the external circuit. A heat shrink tubing 4 is fixedly connected to the bottom of the leads 3. After being heated and shrinking, the heat shrink tubing 4 can tightly adhere to the object being wrapped, forming a sealed, insulating, and... The heat shrink tubing 4 has two wires 5 fixedly connected inside. The top of the wires 5 is in contact with the bottom of the lead wire 3. The heat shrink tubing 4 can protect the connection between the lead wire 3 and the wires 5. The wires 5 are long and thin, which helps to reduce space occupation. The wires 5 are made of copper, which can effectively transmit current and reduce the loss of electrical energy during transmission. The connection between the top of the wires 5 and the bottom of the lead wire 3 is made by tin alloy welding. Tin alloy welding will not easily loosen or break.

[0026] Reference Figure 1 and Figure 2 The connecting ring 2 has an internal slot. The connecting ring 2 is a key connecting and load-bearing component. A circuit board 6 is fixedly connected to the inner wall of the slot. Two leads 7 are fixedly connected to the top of the circuit board 6, and a light-emitting component 8 is fixedly connected to the top of the leads 7. The circuit board 6 is ring-shaped to fully utilize the internal space of the connecting ring 2. The circuit board 6 is made of fiberglass epoxy resin, which resists a certain degree of chemical corrosion and adapts to different working environments. The heat shrink tubing 4 is a long, thin tube. To effectively eliminate gaps and prevent dust, moisture, and other impurities from entering the welding point, the heat shrink tubing 4 is made of polyolefin material, which has good insulation properties and can provide good protection for the welding point. The light-emitting component 8 is shaped like a small square chip, which is conducive to chip encapsulation and heat dissipation management. The light-emitting component 8 is made of gallium nitride, which can maintain its optical and electrical properties in high-temperature environments. The second lead 7 is shaped like a filament, the same as the first lead 3. The second lead 7 is made of copper, the same as the first lead 3.

[0027] Working principle: When soldering lead 3 and conductor 5, lead 3 and the two conductors 5 are wrapped and soldered together. The function of the two conductors 5 is to prevent power transmission through the other conductor 5 if one conductor 5 is damaged and cannot be used, without affecting normal use. After soldering, heat shrink tubing 4 is used to cover the soldered part. When the heat shrink tubing 4 is heated and shrinks, it can tightly cover the soldered part of lead 3 and conductor 5 for protection, effectively eliminating gaps and preventing dust, moisture and other impurities from entering the solder joint.
