Abstract

The invention discloses an LED (light-emitting diode) radiation device which comprises a cylindrical hollow radiation sleeve, wherein a radiating fin array consisting of arc-shaped radiating fins is arranged on the sidewall of the radiation sleeve; a through regulation elongated hole is formed in the sidewall of the radiation sleeve. According to the LED radiation device, positioning fork levers are arranged at the bottom of the radiation sleeve, so that the whole radiation device can be firmly fixed, and the radiation sleeve can be lifted to greatly accelerate the convection of airflow on the radiating fins and effectively improve the radiation efficiency of an LED; in addition, due to the lifted structure, an electronic device on a PCB (printed circuit board) can be effectively prevented from being burnt by the radiation device, and multiple purposes can be achieved; the LED radiation device is simple in structure, convenient to mount and high in practicability.
