Why is the light blinking?

Flickering or from time to time "blinking"light bulbs - a problem that is familiar to many residents of our country. Probably, you have ever been able to fight with such a capricious lamp, which categorically refuses to work in a stable mode. In order to eliminate this problem, you need to first understand the causes that cause it. In fact, flashing or flickering light bulbs in the house can for several different reasons. Let's consider the main ones.

Why does the light bulb flash?

• The first reason is that you changed the light bulb toenergy-saving (LED or fluorescent), and in the switch there is a small bulb showing the way to the switch in the dark. In order for your energy-saving lamp to stop blinking, you must remove this light bulb in the switch. It's pretty simple - parse it.
• The second reason is that someone next to youconducts electric welding work. During the operation of a powerful welding machine in an electrical network that is not designed for impulse welding currents, there is a short, large voltage drop, which causes the lamps in the house to blink frequently.
• The third reason is a wiring fault. If the wiring in the house is old, hidden faults can form in the wires. With the simultaneous inclusion of a large number of powerful household appliances in such a faulty network, worn out wires overheat, this overheating leads to the fact that the lamps in the house start to flicker or wink.
• The fourth reason is faulty contacts incircuit breaker or in the lamp holder. If the switched on lamp starts to wink, and from the switch the characteristic crackle is heard, then the whole reason lies in the bad contacts in the switch. If the circuit breaker is OK, the cause of the flashing may be oxidized contacts in the lamp holder or the bulb may simply not be fully screwed into this cartridge.
• Reason the fifth - it is unstablea transformer substation supplying electricity to your home. In this case, at the moments of peak load or during the switching of the lines, the lamps in the whole house may blink.

Why does the power-saving light bulb flash?

The first reason: the lamp is connected to the network by means of a switch having an LED illumination. To prevent the lamp from flickering, you can:

1. Change it to a normal incandescent lamp.
2. Replace the switch with a backlight with a normal switch.
3. Disconnect the LED lighting from the mains (open the switch and have a bite suitable for the backlight wire).

The second reason is the wrong connection of the lamp. Sometimes an energy saving lamp may flash when a phase and a neutral wire are connected to its switch in the wrong order. In this case, in order to eliminate the flashing of the lamp, it is necessary to interchange the phase and neutral wires in the distribution board located at the entrance to the apartment.
