Humanity is faced with a pressing needsave energy. Therefore, scientists are developing new equipment that meets the high requirements of modernity. This technique consumes less energy than the devices of the last century. Not an exception steel and lighting. Diode and fluorescent lamps were actively used. This significantly saves the family budget. In a global sense, humanity reduces the consumption of electricity and other non-renewable energy sources.
When using the presented lightingdevices, many owners are faced with a small problem. If the light flashes when the lights are off, you should take one of the following actions. This will eliminate the unpleasant effect and fully exploit equipment such as an economical light bulb.
If the energy-saving light flashes whenoff the light, the blame may be several reasons. 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 institutionsused incandescent bulbs. Their device was quite simple. The light bulb has been studying light through the incandescence of a tungsten filament. An electric current was applied to it, which brought the device into action. At the same time quite a lot of electricity was consumed. To illuminate a small room required at least 100 watts per hour.
The housekeeper is able to emit as much lightwhen consumed only 15-20 watts per hour. This device has a special fuse. Through it, the mains voltage (220 V) is applied to the diode bridge. At the exit of it, a glow is produced with a certain pulsation frequency. To make it invisible to the eyes, there is a filtering capacitor in the bulb. That he becomes the cause of flicker.
Illuminated switch can explain whyThe energy-saving light flashes when the light is off. For obvious reasons, such an open circuit device is convenient. No need to look for a switch button in the dark. For this, he has either a special diode indicator or a neon light.
This light source is connected in parallel tocontact device, open circuit. The switch of the type presented has a certain resistance. For a device with LED, this figure is 1 W, and with neon illumination - 0.5-1 W.
When the device is off, it’sA small voltage is first applied to the filtering capacitor of the lamp, and afterwards to the backlight. The resistance value of the switch is negligible. However, it is enough to charge the filter capacitor and create flicker.
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 flaws, but the problem of flicker will be solved. A conventional breaker without backlight would be a more suitable option for economy lamps.
As mentioned earlier, the principle of the device canbecome a reason explaining why the LED light flashes when the lights are off. The second way to solve this problem is to add a small power bulb (25 W) to the network.
Current flowing to the filtering capacitor will bedistributed on a spiral of tungsten filament. Flicker will stop. However, this output is only possible when connecting to a circuit breaker a chandelier with several elements. If the system uses one lamp, this option will be more difficult to apply.
Replacing a power-saving light fixture with an economical outdated product would not be a good idea. Electricity consumption will increase significantly, as will the cost of the family budget.
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 nothas sufficient experience in conducting 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.
Еще одной причиной, объясняющей, почему лампочка flashing 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 switching of conductors. To do this, you must use special equipment, which is necessarily 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.
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.
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.
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.
If the light flashes when the lights are off, italarm signal. Be sure to eliminate the reason why this happens. Especially dangerous if this phenomenon is caused by a deviation in the work of the wiring. Over time, this may cause a fire.
Мерцание также довольно быстро выводит из строя even a very high quality LED lamp. It is not subject to repair. In this case, you must be prepared to incur additional costs for the purchase of new lighting fixtures.
In addition, the flicker is constantly repeated indarkness, can be annoying, negatively affect people's well-being. 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 flickerWith the lights turned 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.
