Energy-saving lamps are quite popular products. But sometimes it is necessary to deal with the fact that they fail. Since the lighting devices are not suiced, it is possible to save their funds if we carry out the repair of energy-saving lamps.

Elements of the lamp and the principle of its action

In order to correctly diagnose the view of the breakdown, you need to know the device of the energy-saving lamp. The modern light source has two main elements:

• gas-discharge flask;
• the electronic unit.

The gas-discharge flask can be made in the form of a spiral or have a U-shaped. The inner part of the flask is covered with a luminophore, and its ends are connected to two spirals.

The electronic unit consists of:

• transistors with medium power:
• chokes;
• diodes;
• high-voltage capacitors;
• high frequency transformer.

After supplying the spiral voltage, electrons are heated and emitted, which, when interacting with the mercury atoms in the flask, form invisible ultraviolet radiation. Ultraviolet falls on the phosphor and the bright light of the lamp is obtained, which for a person becomes visible.

Due to the presence of an oxide layer on the helix, the resistance of the electrode decreases. If this layer is destroyed, the resistance rate increases several times. And this will cause a decline in the life of energy-saving lamps.

Disassembly lamp

It should be noted that to eliminate any fault, the primary check of all elements of the electronic unit is carried out using a multimeter. In particular, to verify:

• the capacitance of the apparatus capacitors of the device is connected to the sockets in the range of 20-200 NF;
• current conductivity in the winding and choke Multimeter is set to the resistance measurement position.

To perform this stage of repairing the energy-saving lamp, you should use two screwdrivers. The inner part of the lamp cartridge is equipped with special latches that need to be disconnected. The process of disassembling the light source resembles the disassembly of the mobile phone or remote control.

The lamp disassembles the following sequence:

• the working part of the screwdriver is inserted between two halves of the lamp housing;
• the tool is spinning in both directions;
• with an increase in the opening, the second screwdriver is inserted into it;
• the first screwdriver is rearranged deeper into the hole and turns again;
• both half of the housing are neatly spread (it is impossible to break the wires).

After disassembling the energy-saving light source, the electronic unit board is carefully examined, which is connected to the flask and the basement. During the disassembly, you can inadvertently abandon the lower part of the cartridge. But do not cost to despair. After repairing the energy-saving lamp, the crack can be searched or stuck.

Determination of faulty elements

To identify the malfunction of energy-saving lamps, alternately check:

• fuse;
• flask;
• diodes;
• stabilirt;
• transistors;
• resistors;
• condensers.

Fuse lamp

Find a fuse will not be much difficulty. One end is connected with the board, and the second is with the central contact of the base. A tube made from insulating material is usually put on the fuse.

When measured, the multimeter is set to resistance measurement mode. One probe applied to the board, where the fuse output is soldered, and the second to contact with the basement. The integrity of the fuse show the testimony of 10 ohms. If the multimeter shows infinity, then the chain is drunk.

Removal of the distilled fuse is carried out closer to its body. So it will be easier to solder a new element.

Flask lamp

After checking the safety of the fuse, the resistance of the filaments of the heat of the flask is measured. For this, on each side there is a decay by one output. The resistance indicator of both threads should be equal. If the value is different, then one of the threads burned.

This problem is solved by solder the resistor located parallel to the failed spiral. The only requirement is the indicators of resistance of the resistor and the second (working) spirals should be the same.

Semiconductors lamp

All semiconductors (diodes, stabilods, transistors, resistors and capacitors) are checked most carefully. This is explained by the fact that these elements fail after short circuits and overloads.

To check the stabilion and diodes, they are not needed. Their "transk" is carried out directly on the board. The direct resistance of the diodes should be about 750 ohms, the opposite is infinity. Performance stabilion indicators are within infinity on both poles.

It is possible to verify the performance of transistors only by sprinkling them, since their transitions are shunting low-voltage transformer winding.

Dropping of burnt resistors is made as follows:

• both sides are warming up;
• with screwdriver, resistors are shifted from the place.

Both operations are done very carefully. Conductors should not turn off the board.

Assembling energy saving lamp

This process occurs in the reverse order. First, resistors are soldered. If solder remains in the contact places (it interferes with the normal fixation of the resistor), it should be removed. To do this, the board is slightly tilted, and the tip of the soldering iron rushes to the contacts. After heating, the solder itself will move to the soldering iron.

The new resistor is stacked instead of a burnt element, aligned, pressed the screwdriver and rolls up on each side. The same is done with the transistors and the fuse.

Before the final assembly of the energy-saving lamp is necessary:

• inspect the places where soldering;
• check the correct installation of all elements;
• perform a trial launch of the light source.

Work on modernization

To increase the service life of energy-saving lamps, you should use the NTC thermistor, and there are ventilation holes in the plastics base.

The thermistor is installed in the incandescent thread break. Thanks to its installation, the number of start-up current is limited, as a result of which the filament is not allowed. The only nuance - the thermistor cannot be recorded near the electronic ballast, since it is very heated.

As for the ventilation holes in the base, then thanks to the incoming air, the optimal temperature regime inside the flask is ensured. The main requirement is such a lamp is not used in rooms with high humidity.
