They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy and have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices.

A groove is provided at the upper end of the base, and threaded holes are provided on both sides of the bottom of the groove. Heat conduction grooves are provided at both ends of the LED light-emitting body, and heat conduction rods are provided in the two heat conduction grooves. The bottom ends of the heat conduction rods are threadedly connected to the threaded holes. At the same time, the fixing method is also convenient for disassembly and maintenance of the LED light-emitting body. At the same time, conductive sheets are installed in the card slots provided on both sides of the bottom of the base, and the connection holes on one side of the conductive sheet are used to connect with the pins at the bottom of the LED light-emitting body, thereby preventing the pins from leaking out and causing damage. The heat conduction blocks installed at both ends of the base are connected by contact with the heat conduction rods, and a number of heat dissipation rods are installed on the heat conduction blocks, thereby solving the heat dissipation problem of the LED light-emitting body.
