LED lamp radiating assembly

A technology for heat dissipation components and LED lamps, which is applied in lighting and heating equipment, cooling/heating devices for lighting devices, lighting devices, etc., can solve the problems of reducing the contact area between the aluminum substrate and the cover plate, increasing the cost, and being unable to dissipate heat. To achieve the effect of not easy to slip teeth, increase the effective number of teeth, and maintain the flatness

Problems solved by technology

[0002] As the cost of LED radiators continues to decrease and the assembly requirements continue to increase, the requirements for the radiator cover continue to increase. The cover before the improvement has a phenomenon of bulging in the middle of the cover during assembly, resulting in a decrease in the contact area between the aluminum substrate and the cover. It is small and cannot dissipate heat well; the round-hole screw holes before improvement are easy to loosen when the aluminum substrate is assembled when there is no connector inside the radiator shell. Once the teeth slip, the entire radiator cover will be damaged Scrapped, increasing follow-up costs

Embodiment 2

[0022] In embodiment 2, such as Figure 4 As shown, the screw hole is provided with an inversion 102, and the inversion protrudes upwards from the cover plate. When screwing the aluminum base plate before the improvement, there is no positioning hole, and manual alignment is required, which is time-consuming and laborious, and may cause misalignment of the holes and misalignment of the screws. It is based on the round hole type screw hole before improvement, and the hole is stretched back, forming a raised shape on the back of the radiator cover, which is convenient for increasing the number of effective threads of the thread when the aluminum substrate is subsequently assembled. Strengthen the fixing effect on the screw, and also play the role of not easy to slip teeth.

[0023] In addition, in this embodiment, the flange 11 is provided with a reinforcing structure, and the reinforcing structure is an indented structure 111 in which the chamfered part is recessed toward the ...

Embodiment 3

[0024] In embodiment 3, such as Figure 5 As shown, the inversion protrudes to the bottom of the cover plate. It stretches the hole on the basis of the round hole screw hole before improvement, so that the aluminum substrate can be directly fixed when the aluminum substrate is screwed, reducing unnecessary time for employees to align the hole, saving time and effort.

Embodiment 4

[0025] Example 4, such as Image 6 As shown, the flange is a U-shaped bending structure, which can increase the heat dissipation area of ​​the cover plate.

Abstract

The invention discloses an LED lamp radiating assembly. The LED lamp radiating assembly comprises a radiator shell, a connecting and inserting piece and a radiator cover plate, and the connecting and inserting piece is arranged in the radiator shell. A supporting ring face is arranged on part, around a center hole of the inner bottom face, of the inner bottom face of the radiator shell. The bottom of the connecting and inserting piece is supported on the supporting ring face. The radiator cover plate covers the connecting and inserting piece. The radiator cover plate comprises a round flat-plate-shaped cover plate body. The cover plate body is provided with screw holes. The connecting and inserting piece is provided with round holes corresponding to the screw holes. An upward flanging is arranged on the edge of the cover plate body. An inner round section is arranged on the upper side of an inner conical section of the inner wall of the radiator shell. The flanging is in contact fit with the inner wall of the inner round section of the radiator shell. A chamfer is arranged at the part, connected with the cover plate body, of the flanging. The screw holes are provided with turning openings. The screw holes are provided with the turning openings, the number of effective teeth of threads can be increased during later aluminum substrate assembling, and the fixing effect on screws is enhanced.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a heat dissipation structure of the LED lamp. Background technique [0002] As the cost of LED radiators continues to decrease and assembly requirements continue to increase, the requirements for radiator cover plates continue to increase. The cover plate before improvement has a phenomenon of bulging in the middle of the cover plate during assembly, resulting in a decrease in the contact area between the aluminum substrate and the cover plate. It is small and cannot dissipate heat well; the round hole type screw hole before improvement is easy to loosen when the aluminum substrate is assembled when there is no connector inside the radiator shell. It is scrapped, which increases the follow-up cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat dissipation assembly for an LED lamp, which avoids slippage of wires coming out of s...
