[0002] LED heat dissipation technology was born in 2000. It is made of semiconductor light-emitting diodes. The working principle is electroluminescence generated by radiation recombination. It is the most common heat dissipation method. Aluminum heat sink fins are used as part of the outer shell to increase the heat dissipation area.

[0003] Existing heat dissipation devices for LED lamps generally use fans for active heat dissipation. However, when the heat dissipation fan is damaged, the LED lamp heat dissipation device needs to be completely disassembled. This disassembly method is very cumbersome and time-consuming. In view of this, we propose a heat dissipation device for LED lamps. Utility Model Content

[0015] 2. When the LED lamp of the device fails, the U-shaped pins on both sides of the shell are pulled out to separate the lampshade from the shell, and the second rotating wheel is rotated. The rotation of the second rotating wheel drives the rotation of the second screw rod, and the lifting frame is lowered at the same time. When the lifting frame is lowered to a specific height, the circuit board is removed and repaired and replaced; at this time, the circuit board is placed above the lifting frame, and the second limiting holes on the circuit board are connected with the limiting columns on the lifting frame one by one, and then the second rotating wheel is rotated to make the lifting frame rise until the circuit board abuts against the copper base plate and then stops; through the above operation, not only the stability of the circuit board after installation is enhanced, but also the thermal conductivity of the copper base plate will enhance its heat dissipation effect, thereby increasing the service life of the LED lamp.
