The cause of the LED street light death light have?
the LED street lamp LED solar street light the lamps and lanterns temperature protection and automatic temperature adjustment function failure when aluminum plate * open the lamp cover, high temperature test short-circuit temperature control switch, disconnect the negative temperature coefficient thermistor ( NTC） , the LED street lamp lost temperature protection and automatic adjustment function of lamps and lanterns, guarantee to the full power of lamps and lanterns. In the central area of lamps and lanterns aluminium base PCB put thermocouple temperature sensor or 71 ℃ irreversible temperature indicating labeling. Then according to the normal work of the back cover, according to the normal work of lamps and lanterns up in 30 ℃ temperature by + / - 1 ℃ windless room or wind cap inside, and then to the lamps and lanterns of tong to 1 rated frequency and voltage of the rated voltage. Double power supply, continuous light 24 h, with the right temperature recorder with continuous monitoring the temperature of the thermocouple temperature sensor of the aluminium base PCB, if * high temperature does not exceed 71 ℃, the aluminum substrate * high temperature test, the opposite is unqualified, or open the cover when the power is to observe the temperature indicator whether to change the black, if there is no black, I didn't explain aluminium base PCB temperature reached 71 ℃, the aluminum substrate * high temperature test, the opposite is unqualified.
