A: The LED ceiling light shorted after being struck by lightning, need to replace the damaged parts for repair.
deep analysis
After the LED ceiling light encounters lightning, it usually damages the power circuit and LED light source, resulting in normal work. The repair method is as follows:
1. Check the appearance for damage. The LED ceiling light struck by lightning has obvious burn marks on the housing and internal components, which need to be cleaned and repaired.
2. Check the power input. Use a multimeter to check whether the input voltage is normal. If the input voltage is normal and the lamp is not bright, the power circuit is likely to be damaged.
3. Replace the power circuit. There is a high probability that the power circuit board is burned or the capacitor is damaged by lightning, and a new power circuit board needs to be replaced. Damaged capacitors and other parts can also be replaced for repair.
4. Check the LED light source. LED light source is also often damaged, you need to use a flashlight from the ceiling lamp heat dissipation hole to observe whether there is obvious damage to the LED chip, such as seeing the chip surface scorched may need to replace the new LED light source.
5. Replace the cable. Lightning will be transmitted to the ceiling light through the connecting cable, burning the connecting cable, need to replace the lead cable connected to the power supply and the cable connected to the LED light source.
6. Assembly and debugging. After installing the new power circuit board, LED light source and connection line, reassemble the ceiling light, power test whether the function is normal, and no abnormal debugging can be used normally.
Due to the damage of LED ceiling lights after lightning strikes is more complex, generally speaking, the maintenance difficulty and cost are higher. In addition to the above part replacement, the drive circuit and other connecting parts may also need to be replaced. If the damage is more serious and the maintenance cost is close to the new purchase price, it is more recommended to buy new lamps.
Although the repair of LED ceiling lights after lightning strikes is more troublesome, but as an energy-saving and environmentally friendly lighting product, it is worth consumers to try to repair the use of conditions. In particular, some high-quality and high-priced products, repair and use can better play their use value, but also in line with the concept of environmental protection and energy saving.
Give quality advice:
1. Disconnect the power supply immediately after lightning strikes to ensure personal safety.
2. Choose a professional electrician for evaluation and maintenance, and generally individuals are not recommended to operate by themselves.
3. If the maintenance cost is too high after evaluation, you can consider replacing new products with similar quality.
4. After maintenance and use, a comprehensive functional test should be conducted to ensure safety performance before it can be used again.
5. Improve lightning protection measures, choose products with lightning protection devices, install special lightning protection lines, etc.
6. Avoid lightning weather try not to use high-power electrical appliances to avoid lightning strikes caused by fire.
7. LED products made of environmentally friendly materials are more worthy of repair and use to maximize their use value.
8. Purchase professional maintenance warranty for high-priced quality products, which can reduce maintenance costs.
Need to replace the damaged parts or replace the lamp as a whole because lightning can cause instantaneous strong current to the circuit, thus damaging the components in the circuit, LED ceiling light damage may be due to the circuit board, power capacitor or overall damage caused; Repair the damaged parts need to be repaired or replaced, in the replacement can take into account the cost of materials, maintenance difficulty and can guarantee the appearance of the original lamps and other factors.
If the repair capacity is too low, or the replacement cost is too high, you can consider replacing a new LED ceiling light, it is recommended to buy a brand that meets the safety requirements of electrical appliances, and you need to pay attention to the quality assurance and after-sales service of some brands.
Need to replace the lamp or repair the circuit because when the LED ceiling lamp is damaged by lightning, it may cause damage to the lamp itself, and may also affect its circuit system, so the damaged part needs to be detected.
If there is a problem with the lamp itself, the lamp needs to be replaced; If there is a problem with the circuit, the circuit needs to be repaired.
In addition, in order to prevent similar situations from happening again, you can consider installing lightning protection devices when installing LED ceiling lights or closing the lamps in time when it rains to reduce the risk of lightning strikes.
Check the wiring. If not, just change the lights.
