[0002] An LED power supply is a power supply device used to drive LED lamps. Its main function is to convert alternating current into direct current and provide stable current and voltage to ensure the normal operation of the LED. Most of the outputs of LED power supplies are constant current sources whose voltage can change with the forward voltage drop value of the LED.

[0003] Currently, the disadvantages of LED power supplies with overheat protection functions on the market are as follows: The output terminals of general LED power supplies are connected to multiple LEDs, but most of the connection methods use the way of screwing tightly for installation. Therefore, when connecting multiple LEDs, it is more cumbersome, and a screwdriver needs to be carried during installation, which is rather inconvenient. For this reason, we have designed an LED power supply with an overheat protection function. Content of the Utility Model

The top of the spring 207 is fixedly connected to the bottom of the fixing plate 202. The bottom of the cylinder 203 is fixedly connected to the center of the top of the movable plate 206. A groove is opened at the top of the cylinder 203, and a fixing rod 208 is fixedly connected to the inner wall of the groove. A guide rod 209 is movably connected to the surface of the fixing rod 208. One end of the guide rod 209 is rotatably connected to a semi-circular block 210. The bottom of the semi-circular block 210 is fixedly connected to one side of the top of the fixing plate 202. The other end of the guide rod 209 is fixedly connected to a threaded rod 211. A nut 212 is threadedly connected to the surface of the threaded rod 211. An L-shaped block 213 is fixedly connected to one side of the fixing plate 202. A clamping groove 214 adapted to the threaded rod 211 is opened at the top of the L-shaped block 213. Insert the power cord or the connecting wire of the LED into the corresponding connecting block 201, press down the end of the guide rod 209 with the threaded rod 211, so that the guide rod 209 moves on the surface of the fixed column and drives the cylinder 203 to descend, thereby pushing the movable plate 206 to descend, and at the same time stretching the spring 207, thereby making the movable plate 206 slide inside the support rod 204 to clamp the wire placed on the top of the connecting block 201. Push the threaded rod 211 into the rectangular slot 103 at the top of the L-shaped block 213, and then rotate the nut 212 until it rotates to one side of the rectangular slot 103 to fit the L-shaped block 213, making it difficult for the movable plate 206 to move, and the connection of the LED wire can be completed, which plays a role in facilitating the installation of the LED wire, improves the speed of installing the wire, and does not require a screwdriver during installation, increasing the convenience during installation.

Protective shells 8 are fixedly connected to the surfaces of the rectangular grooves 103 on both sides of the rectangular box 101. Among them, the protective shells 8 can block a part of the rectangular grooves 103 on both sides of the rectangular box 101.

[0024] Furthermore, a number of first trapezoidal grooves are formed in the top of the connecting block 201, and a second trapezoid meshing with the first trapezoidal grooves is formed in the bottom of the movable plate 206. Among them, the meshing of the first trapezoidal grooves and the second trapezoidal grooves can prevent the wire from falling off easily after clamping the wire.

[0025] In the present utility model, the working steps of the device are as follows:

[0026] First step: Insert the power cord or the connecting wire of the LED into the corresponding connecting block 201, press down the end of the guide rod 209 with the threaded rod 211, so that the guide rod 209 moves on the surface of the fixed column, and drives the cylinder 203 to descend, thereby pushing the movable plate 206 to descend. At the same time, the spring 207 is stretched, so that the movable plate 206 slides inside the support rod 204 to clamp the wire placed on the top of the connecting block 201. Push the threaded rod 211 into the rectangular groove 103 on the top of the L-shaped block 213, and then rotate the nut 212 until it rotates to one side of the rectangular groove 103 to fit the L-shaped block 213, making it difficult for the movable plate 206 to move, and the connection of the LED wire can be completed.

[0027] Second step: The fan 5 can be started when the temperature of the circuit board 102 is too high, inhale external air from the air intake groove 6 at the bottom of the rectangular box 101, dissipate heat from the circuit board 102, and finally discharge the hot air through the air outlet groove 4, thereby reducing the occurrence of short circuit caused by overheating of the circuit board 102.
