LED lamp is a lighting device that uses light-emitting diodes as a light source. LED lamps have many advantages, including high efficiency and energy saving, long life, environmental protection and pollution-free, anti-vibration and vibration, fast start-up, dimmable and other characteristics. The following will introduce how to fix the LED flashing after turning on the light.
1. Power supply problem
1. Check whether the power socket is firmly plugged in. If it is firmly plugged in, unplug the power supply and try to plug it in again after a few minutes;
2. Check whether the power cord is damaged or has poor contact. Unplug the power cord and check whether the wire is obviously worn or damaged. If so, replace the new power cord;
3. Check whether the power adapter is working properly. You can use a multimeter to measure the output voltage and current of the adapter. If it is not within the standard range, you need to replace a new adapter.
2. Wiring problem
1. Check whether the connection between the bulb and the power cord is firm. Open the lampshade and check whether the interface between the bulb and the power cord is loose. If it is loose, reinsert and fix it;
2. Check whether the connection between the power cord and the bulb base is good. Tighten the screws at the connection to ensure good contact.
3. LED bulb problem
1. Check whether the bulb is burned out. You can connect the bulb to another power source for testing. If it does not flicker, you need to replace it with a new bulb;
2. Check whether the light-emitting diode of the bulb is normal. Observe in the dark whether there is an obvious blackout point or damage on the luminous part of the bulb. If so, you need to replace it with a new bulb.
4. Switch problem
1. Check whether the switch is damaged. Use a multimeter to measure the conduction of the switch. If it cannot be conducted or the contact is poor, you need to replace a new switch;
2. Check whether the switch wiring is good. Open the switch cover and check whether the circuit is in good contact. If there is a problem, rewire and fix it.
