Mankind has faced a pressing needto save energy resources. Therefore, scientists are developing new equipment that meets the high demands of the present. Such a technique consumes fewer energy resources than the devices of the last century. Not an exception, steel and lighting equipment. Diode and fluorescent lamps became active. This significantly saves the means of the family budget. In a global sense, mankind reduces the consumption of electricity and other non-renewable energy sources.
When using the presented lightingdevices many owners have encountered a small problem. If the light is blinking when the light is off, you should take one of the following actions. This will eliminate the unpleasant effect and fully exploit such equipment as an economical light bulb.
The principle of the lamp
If the energy saving lampoff light, there can be several reasons for this. To understand how to solve this problem, it is necessary to consider the principle of operation of such equipment.
Most recently in most homes and institutionsincandescent lamps were used. Their device was quite simple. The lamp studied the light by incandescent tungsten filament. An electric current was applied to it, which activated the device. It consumed quite a lot of electricity. To illuminate a small room, a minimum of 100 watts per hour was required.

The housekeeper is capable of emitting as much lightwhen consuming only 15-20 watts per hour. This device has a special fuse. Through it, the mains voltage (220 V) is fed to the diode bridge. At the output of it, a glow with a certain pulsation frequency is obtained. To make it invisible to the eyes, the bulb has a filtering capacitor. It is he who causes the flicker.
Illumination of the switch
A switch with illumination can explain whyThe energy saving lamp blinks when the light is off. For obvious reasons, such a device breaking the circuit is convenient. You do not need to look for a switch in the dark. To do this, it has either a special diode indicator, or neon lights.
This light source is connected in parallel tocontact of the device breaking the circuit. A switch of the type shown has a certain resistance. For a device with a light-emitting diode this indicator makes 1 W, and with neon illumination - 0.5-1 W.
![The energy saving lamp is blinking when the light is off](/images/domashnij-uyut/pochemu-migaet-lampochka-pri-viklyuchennom-svete_2.jpg)
When the device is turned off, thisa small voltage is first applied to the filter capacitor of the lamp, and afterwards to the backlight. The value of the resistance of the switch is negligible. However, it is sufficient to charge the filter capacitor and create a flicker.
The first solution to the problem
It should be noted that neon lights createrarer flashes of a lamp, than a diode version. It has less resistance in the circuit. Therefore, the filter capacitor charges more slowly. If the LED light flashes when the light is off due to a similar reason, it can be solved radically. The backlight is simply excluded from the circuit. To do this, disassemble the switch and open the backlight contact with the device.
This solution is not without its shortcomings, but the problem of flicker will be solved. A conventional device that disconnects the circuit, without backlighting, will be more suitable for economical lamps.
The second way to fix the problem
As it was said before, the device principle canto become the reason, explaining why the LED light is blinking when the light is off. The second way to solve this problem is to add a small incandescent light (25 W) to the network.
![The LED light is flashing when the light is off](/images/domashnij-uyut/pochemu-migaet-lampochka-pri-viklyuchennom-svete_3.jpg)
The current flowing to the filter capacitor will beTo be distributed on a spiral of a tungsten filament. Flicker will stop. However, this output is possible only when connecting a chandelier with several elements to the circuit breaker. If one lamp is used in the system, this option will be more difficult to apply.
Replacing a power-saving light fixture with an uneconomical outdated product would not be a good idea. Electricity consumption will increase significantly, as will the cost of the family budget.
Another solution
If the light flashes when the light is off, you cansolve the problem in another way. If the chandelier consists of only one cartridge, the additional element in it will not be easy to install. Instead of the previous option, you can replace the incandescent lamp with an additional element of resistance with a power of about 2 watts. This will be enough to get rid of annoying flicker.
This method is rather unsafe if the master is notHe has sufficient experience in carrying out such work. Resistance must be soldered to the circuit parallel to the lamp. This will allow to divert the current flowing to the backlight from the filtering capacitor.

This option is considered the most unsafe. The resistance element may heat up. It is better to disconnect the power of the backlight or purchase ordinary switches. It will be safe and efficient.
Wrong connection
Another reason why the light bulbflashing when the light is off, there may be a wrong wire connection. The network usually consists of 3 wires - zero, phase and ground. An inexperienced electrician may confuse them. As a result, the switch connects to the conductors incorrectly.
If you confuse the phase and zero, the lightwill flicker. In this case, when turned off, it will break not the phase, but zero. To correct the situation will allow the switching of conductors. To do this, you must use special equipment, which is mandatory in the arsenal of an electrician.
Even with the help of an indicator screwdriver, you can check which cable is energized. After testing the wiring, it will be easy to change the wiring if necessary.
Poor wiring
Another factor that causes the diode to flashlight when the light is off, there may be poor-quality wiring. If the power grid has not been updated for many years, there may be a large leakage current.
![Why the light flashes when the light is off](/images/domashnij-uyut/pochemu-migaet-lampochka-pri-viklyuchennom-svete_5.jpg)
In this case, the replacement of the entire power line is required, otherwise everything can end in a rather pitiable way. Old wiring leads to fire and other accidents.
If the wires are new, it should be installed in the circuitRCD and make a full ground. Modern requirements for electrical safety allow you to perform this process on the system TN-S, TN-C-S. In this case, if leakage currents, the RCD will disconnect the power supply of the damaged conductor. This is an effective protection of communications and property owners from unforeseen situations.
A few more reasons
Sometimes it happens that the light flashes whenoff light due to faulty product itself. In this case, you can only recommend not to save on such devices. Also, do not purchase economical lamps from a dubious seller.

Но даже при правильном подключении и полностью A good lighting device may cause flickering due to waves generated by strong electromagnetic devices. If you bring a diode lamp, for example, to a TV, it will also light up. In this case, you must either remove the radiation source or replace the lamp with an old-fashioned device.
Why do I need to eliminate flicker?
If the light flashes when the lights are off, italarm signal. Be sure to eliminate the reason for this. Especially dangerous if this phenomenon is caused by a deviation in the work of the wiring. Over time, this may cause a fire.
Flicker also pretty quickly disableseven a very high quality LED lamp. It is not subject to repair. In this case, you need to be prepared for additional costs for the purchase of new lighting fixtures.

In addition, the flicker is constantly repeated indarkness, can be annoying, negatively affect the well-being of people. This is especially noticeable in those rooms in which a person spends a large amount of time at night (bedroom, children's room). In this case, measures to eliminate unpleasant flicker should be taken immediately.
After reviewing the possible causes of flickerWhen the light is off, you can eliminate this problem quickly and efficiently. This is necessary to extend the life of the light fixture and to avoid unexpected troubles in the future.
