  • Led luminaire common fault repair method

    Led luminaires common fault repair methods. First, the LED energy-saving lamps have obvious damage to the components 1. If the high-frequency transformer B is damaged, it can be wound on a high-frequency magnetic ring of 10mm×6mm×5mm with a ∮0.32mm high-strength wire. Each of T1 and T2 is 4 turns; T3 is 8 turns (note the head and tail). Choke L: The lamp power is 5 to 40 W, which corresponds to between 1.5 and 5.5 mH. 2. Although the fuse is not blown, the line at the incoming line is not burned, and the resistance is obviously damaged, the triode will be undoubtedly damaged. This may be caused by aging of the lamp, followed by poor use of the environment, and possibly by the loss of capacity of C1. For the first two cases, it is best to replace the paired C3 and C4 small electrolysis when replacing the resistor and the triode. For the latter type, C3 and C4 do not have to be replaced. Since C1 works under high pressure conditions, it is necessary to replace it with high quality heat r...
