Why the energy-saving lamp is flashing

If you compare incandescent and energy-saving lamps, then the second stand a step higher. This light source is much better and more progressive. Therefore, incandescent lamps are encountered less and less, and housekeepers, although more expensive several times, confidently drive them out of our homes. Having bought such a lamp, we have the right to expect from it an impeccable job. Basically so it is, but sometimes sometimes energy-saving lamps start to flash. Why is the energy saving lamp blinking? Our article will answer this question.

Design

energy-saving lamp energy saving lamp design includes:

• flask. The form is very diverse;
• two spirals;
• electronic ballast.

Operation of the energy-saving light bulb

The principle of operation is the same for both fluorescent and energy-saving lamps:

1. A glow discharge occurs between the 2 electrodes placed in a flask into which inert gas and mercury vapor is pumped.
2. The invisible ultraviolet radiation of mercury atoms during passage through the walls of the bulb, coated from the inside by the phosphor, turns into light, which we see. At the same time, the color of light is different, it all depends on the composition of the lamp from the inside.

Interesting : Despite the fact that in our networks the voltage is variable, the energy saving lamp works on a constant. Conversion of DC to AC voltage occurs in the electronic starter using a diode bridge.

Why the energy-saving lamps of

blink While penetrating the idea of ​​saving energy, a person threw out all the usual old lamps in the house and put energy-saving lamps. And how unpleasant it is when they suddenly start to flash.

Bulbs blink differently

The energy saving lamps flash in different circumstances:

• is constantly flashing when the switch is on;
• at the moment of switching on and some short time after;
• periodically;
• even when the switch is off.

The lamp is off, but the

is blinking. Why is the energy saving lamp blinking, because there is no voltage in the network? And it turns out that it's not in the lamp, but in a switch with LED or neon lights. And here's why:

1. Power contacts close as soon as we turn off the switch.
2. The lamp, which lights up, starts to burn.
3. The electric current of a very small amount from the network passes through a lamp, a chandelier with energy saving light bulbs on the ceiling and again returns to the network. In this case, the capacitor in the electronic circuit of the energy-saving light bulb is recharged and the light flashes.
4. The capacitor instantly discharges and again everything repeats in a circle. That's the whole secret of the blinking off of the energy-saving lamp.

Conclusion: can not combine a switch with a backlight and an energy-saving lamp. Even if you are not annoyed by flashing, then think about how much faster your not so cheap lamp worn. Because of the large number of launches, it will quickly spend the resource in it, and after a maximum of 2 months it will have to be discarded.

There may be other reasons, namely:

• errors in the installation of electrical wiring;
• lamp produced by an unscrupulous manufacturer.

The light is blinking when the switch

is on. As soon as the light comes on, the light starts flashing. The phenomenon is very unpleasant, but what is its cause:

1. The level of voltage in the network is so low that the ballast of the energy-saving lamp can not start it in operation. If so, then take the multimeter, bring it to the outlet and measure the voltage. If there is a deviation from normal( 220 V) from 5%, we turn to the company engaged in electricity supply with a complaint about the mismatch of the quality of supplied electricity to the established standard. After all, not only light bulbs, but also household appliances can come out of the system.
2. The start-up device of the energy-saving lamp is faulty. There is nothing else left to do but to buy a new lamp, becauseold repair is not subject.
3. There are voltage surges on the network. All claims to the power supply company, unless, of course, you do not perform welding operations by incorporating a welding inverter into the network of the house. Then the reason is there, and you can not do it.

The energy saving lamp flashes after the

is turned on. This phenomenon occurs when you have an energy-saving fluorescent lamp with an electromagnetic start system. With such a malfunction of energy-saving fluorescent lamps, like a fired starter, a slow start occurs. Delay up to 10 sec.still permissible, but if more, change the starter.

Elimination of the causes of flashing energy-saving lamps

If, when buying lamps, you put quality first and not the lowest price, then the issue of malfunctioning energy-saving lamps disappears. It remains to look for the cause in the other and eliminate it:

1. The first and easiest way to get rid of the blinking of the lamp in the off state is to open the light switch and open the circuit through which the current flows to the light bulb. The capacitor stops feeding and the lamp stops blinking.
2. The second way is radical - change the switch with a light bulb for a normal one.
3. The third is a compromise, i.e.and blinking eliminates and the switch with backlight remains. A small current, recharging the capacitor, is neutralized by screwing into the chandelier of 2 or more light bulbs 1 of the incandescent bulb. Of course, this will somewhat reduce the energy savings, but will allow the current to be drained from the condenser for filament incandescence. There is one more positive moment in this method:

• the energy saving lamp turns on gradually, and the incandescent lamp immediately, then the chandelier will light up faster;
• the color of the energy-saving lamp is not always comfortable, and in combination with the light of a conventional lamp, this defect is compensated. By the way, your eyes will get tired less.

4. The fourth method technically duplicates 3, only the addition will be not an incandescent lamp, but a capacitor or a 2 W resistor with a resistance of 50 kΩ as a shunt element. Through it will go the current small, but sufficient to ensure that the backlight works.

Energy-saving lamps of high quality

Buying energy-saving lamps, take for yourself the rule of paying attention to who is the manufacturer. No doubt the quality of lamps, from a well-known manufacturer like Philips( Philips).These lamps have good characteristics:

• heat dissipation is negligible;
• serves for a long time;
• saves electricity by 80%;
• turns on without blinking;
• provides a luminous flux of 85%.

Another leader in the production of lighting equipment is the German company Osram( Osram).This brand is very popular, and the lamps from the OSRAM DULUX SUPERSTAR and OSRAM DULUXSTAR series differ:

• is warm, pleasant, like incandescent light;
• almost instantaneous achievement of the planned luminous flux;
• excellent light output;
• long service life - 15 thousand hours;
• compact, attractive design.

Malfunctions of energy-saving lamps

What are the malfunctions of energy-saving lamps and methods for their elimination consider the example of PHILIPS 6yr 23W ECONOMY.

Dismantling of energy-saving lamps

We dismantle the case of the energy-saving lamp in the following sequence:

• we take a flat screwdriver and, moving gently along the perimeter, push out the latches;
• disconnect the bulb of the lamp, unscrewing the 4 wires with which it is connected to the electronic unit;
• perform a tap-off of the wires connecting the base and the board. In the hands will remain a block. Now it is possible to determine the malfunction.

Frequent faults:

1. If the network is experiencing an increased voltage, the capacitor will swell and flow, and the lamp will stop lighting. It requires a CD replacement and testing of all semiconductors.
2. For the same reason, there is such a malfunction as the breakdown of the capacitor C5.The lamp is lit only where the filaments are. We change the capacitor.
3. The cause of the incomplete illumination of the lamp can be a rather long operation. At the same time, the sealing of the flask is partially broken, the thermionic emission decreases. We throw out the lamp.
4. When one of the filaments breaks, the lamp ceases to burn. In this case, we check the serviceability of the capacitor C5.Where the glow is cut off, we dissolve the diode, and in its place we insert a 10 ohm resistor.
5. Another reason for the failure of an energy-saving lamp is a faulty diode thyristor( dinistor).This cause is detected by eliminating the malfunction of semiconductors, capacitors, windings of chokes, filaments. Exit is the replacement of the defective item.
6. If, by ringing resistors and semiconductors, you see that they are out of order, then the parts, of course, must be replaced. But think, whether it is necessary to do it, after all such repair will manage expensively. It's easier to buy a new lamp.
