[0002] The plastic-coated aluminum lamp is a kind of LED lamp. With the development of LED lighting technology, LED lamps are gradually popularized due to their advantages such as energy saving, environmental protection, and long service life. However, in practical applications, the heat dissipation performance, waterproof performance, and electrical safety of LED lamps have become one of the key factors affecting their reliability and service life.

[0003] At present, for the two energized wires of the LED chip of the plastic-coated aluminum lamp in the market, generally one is directly connected to the conductive nail of the lamp head, and the other is conductively connected to the conductive sleeve. Generally speaking, the longer the length of the energized wire bent out, the more stable the connection. However, there is also a problem. Sometimes when the energized wire is too long, the lamp head cannot completely cover the energized wire, and the head of the energized wire is exposed, which affects the product quality; or when the energized wire is too long, the head of the energized wire needs to be cut, which increases the operation steps and affects the production efficiency.

[0004] The present utility model is made based on the above situation. Content of the Utility Model

[0028] The following further describes the present utility model in conjunction with the attached drawings:

[0029] As Figures 1 to 5 shown, a wire threading structure of a plastic-coated aluminum lamp socket includes a radiator 1, a waterproof decorative part 2, and a lamp head 3. A placement groove 11 for placing a light source assembly is provided on the radiator 1. A connecting column 12 is provided on the back of the radiator 1. The waterproof decorative part 2 is sleeved on the connecting column 12. The lamp head 3 is sleeved on the end of the connecting column 12 to prevent the waterproof decorative part 2 from coming off. A first through-hole 121 communicating with the placement groove 11 is provided on the connecting column 12. A wire threading groove 21 for allowing a wire 40 to pass through is provided between the outer wall of the connecting column 12 and the inner wall of the waterproof decorative part 2. The wire 40 is blocked by the waterproof decorative part 2 and is not exposed.

[0030] A threading groove 21 for the wire 40 to pass through is provided between the outer wall of the connecting column 12 and the inner wall of the waterproof decorative part 2. The length of the energized wire 40 bent out can be appropriately lengthened, so that the connection between the wire 40 and the lamp holder 3 is more stable. The head of the wire 40 that is too long can be inserted into the threading groove 21, so as to avoid the head of the wire 40 being exposed and affecting the product quality, and there is no need to cut the wire head. The waterproof decorative part 2 is sleeved on the end of the connecting column 12 through the lamp holder 3 to limit its escape, so that the waterproof decorative part 2 does not need to be fixedly connected by processing buckles or other connecting structures, which reduces the structural cost of the mold and is more convenient for processing and molding.

[0031] In some embodiments, the lamp holder 3 includes a conductive sleeve 31 and a conductive nail 32 connected to the conductive sleeve 31, an insulating block 33 is provided between the conductive sleeve 31 and the conductive nail 32 to insulate the two, and the connecting column 12 and the heat sink 1 are an integrated structure. The above-mentioned conductive sleeve 31 can be pressed into the connecting column 12 by mechanical pressure to complete the fixed connection, and of course the conductive sleeve 31 can also be fixedly connected to the connecting column 12 by glue or other connection methods.

[0032] In some embodiments, the back of the heat sink 1 is provided with a second through hole 13 which is connected to the placement groove 11 and is used for threading or ventilation, and the second through hole 13 is connected to the threading groove 21. The two power wires 40 of the LED chip can both pass through the first through hole 121 to be connected to the lamp holder 3, or one can directly pass through the first through hole 121 of the connecting column 12 to be connected to the conductive nail 32 of the lamp holder 3, and the other can pass through the second through hole 13 to be connected to the conductive sleeve 31. The independent threading through hole can reduce the electromagnetic interference between the two wires 40, which helps to improve the signal stability and the working performance of the lamp; at the same time, the second through hole 13 helps to improve the air circulation inside the lamp, thereby facilitating heat dissipation, which is beneficial to improving the overall performance and life of the LED lamp.

[0033] Specifically, the waterproof decorative member 2 covers the outer side of the second through hole 13, so that the water flow to the second through hole 13 is limited by the waterproof decorative member 2, and a transition cavity 22 is provided on the inner side of the waterproof decorative member 2, and the second through hole 13 and the threading groove 21 are both connected to the transition cavity 22. The transition cavity 22 can also further improve the heat dissipation performance of the radiator 1.

[0034] Furthermore, a waterproof fence 131 surrounding the second through hole 13 is provided on the back of the radiator 1. When the waterproof decorative element 3 is accidentally flooded, the waterproof fence 131 can further prevent water from flowing into the radiator 1 and affecting the LED chip. The waterproof fence 131 and the radiator 1 are an integrated structure.

[0035] Further, a plurality of second through holes 13 are provided on the back of the radiator 1, and the plurality of second through holes 13 are evenly distributed outside the connecting posts 12. The heat dissipation performance is enhanced through the plurality of second through holes 13.

[0036] As Figure 6 shown is a schematic diagram of the wire threading method of the existing plastic-coated aluminum lamp. The existing aluminum blank is arc-shaped and requires multiple processes of progressive die to form an arc surface. Moreover, the progressive die processing wastes materials, has many processing steps, and slow processing efficiency. The radiator 1 in this case is made of plastic. The radiator 1 includes an inner ring wall 16 in the shape of a cylinder or a frustum of a cone. One end of the inner ring wall 16 is provided with a bottom wall 15 with a flat or inclined surface. A placement groove 11 is formed by enclosing the inner ring wall 16 and the bottom wall 15. The wire threading structure further includes an aluminum cup 6 connected in the placement groove 11 through a plastic-coated aluminum process. The aluminum cup 6 is adapted to the shape formed by enclosing the inner ring wall 16 and the bottom wall 15. The aluminum cup 6 can be stamped out through a single punching die, with high material utilization rate, few processing steps, and high processing efficiency.

[0037] In some embodiments, a broken line groove 123 for further restricting the displacement of the wire is provided at the end of the connecting post 12.

[0038] In some embodiments, a flange 311 for shielding the wire threading groove 21 is provided at the port of the conductive sleeve 31. The wire threading groove 21 can be shielded by the flange 311 to improve the aesthetics of the lamp socket, and at the same time, it also has a certain waterproof function. Specifically, the flange 311 is bent or punched outwards from the port of the conductive sleeve 31.

[0039] In some embodiments, a limiting step 122 is provided on the inner wall of the first through hole 121. When an electrical component is provided in the first through hole 121, the displacement of the electrical component to the lamp head 3 can be restricted by the limiting step 122, reducing the risk of short circuit.

[0040] In some embodiments, a limiting structure for restricting the relative rotation between the radiator 1 and the waterproof decorative member 2 is provided. Specifically, the limiting structure includes a raised rib 14 provided on the radiator 1 and a limiting groove 23 provided on the waterproof decorative member 2 and for the raised rib 14 to be inserted into to restrict the rotation of the waterproof decorative member 2.
