Abstract

The invention relates to a cooling failure processing method for a light emitting diode (LED) lamp. A cooling device is used for failure processing and comprises a radiator, wherein the radiator is arranged on an LED circuit board; a base plate is connected onto the radiator; a temperature sensor, a control circuit and a driving power supply are arranged on the base plate; the control circuit and the driving power supply are used for controlling the radiator to dissipate heat; the control circuit comprises a comparison circuit and an electronic switch; the temperature sensor is used for acquiring temperature information of the radiator and comparing the temperature information with an maximum temperature; when the temperature of the base plate is higher than the maximum temperature, the power supply to the LED lamp is cut off; when the temperature of the base plate is reduced to be lower than the maximum temperature, the power supply to the LED lamp is switched on; and when the temperature of the base plate is risen to be higher than the maximum temperature again, the power supply to the LED lamp is cut off again. The turning on and off of the LED is controlled by the control circuit and the electronic switch; and when the temperature is overhigh, the power supply to the LED is cut off timely by the electronic switch, and an LED street lamp is prevented from being damaged or the service life is prevented from being shortened due to the heat dissipation problem.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a heat dissipation fault processing method for LED lamps. Background technique [0002] LED is a semiconductor that can convert electrical energy into visible light.
