Abstract
An LED lamp radiator comprises a radiator body, a fan connected with one end of the radiator body, a motor connected with the other end of the radiator body, a blocking piece tightly close to the inner wall of the radiator body and a controller arranged in the radiator body. A chute is formed in the inner wall of the radiator body, and a protrusion is arranged on the outer wall of the blocking piece and is arranged in the chute. Multiple heat dissipation holes are formed in the side wall of the end close to the motor, of the radiator body. An output shaft of the motor is connected with a screw, a connecting frame is arranged on the on the inner wall of the blocking piece and is connected with a nut sleeve, the nut sleeve is connected with the screw, and the fan and the motor are electrically connected with the controller. When the LED lamp radiator is electrified, the fan and the motor are started simultaneously, the motor rotates to drive the blocking piece to move and open the heat dissipation holes, and wind blown out by the fan can be quickly exhausted through the heat dissipation holes and accordingly carries away heat. When the LED lamp radiator does not work, the fan stops rotating, and meanwhile the motor reversely rotates to enable the blocking piece to close the heat dissipation holes, so that the safety of the LED lamp radiator can be improved.
