Common faults and maintenance of LED flashlight

by:Light Squared     2024-01-11
Maintenance of common faults: 1. LED dead light does not light up, just replace the LED, but be careful not to reverse the polarity of ±.
2. The lead-acid battery is damaged, causing it to be unable to charge and discharge, and it can only be used when it is plugged in.
3. The high-voltage step-down capacitor is damaged, or the rectifier diode is damaged by overvoltage, resulting in failure to charge. At this time, an ordinary pointer-type multimeter can be used to detect and solve the problem.
4. The pull switch is in poor contact or damaged and cannot be turned on.
