Do-it-yourself energy-saving lamp repair: features, step-by-step instructions and recommendations
This article provides a classification of energy-saving lamps. Shows the order of their disassembly and verification of elements. Recommendations for troubleshooting.
Energy-saving lamps (ECL) are gradually becoming the main source of light both in the manufacturing sector and in everyday life. Their advantages are undeniable. Energy savings, high efficiency and light output, long service life and low heating make them one of the most promising electrical devices in the near future.
Scientists are conducting research to improve the quality of ECL. Positive results are not long in coming. However, it is not yet possible to completely eliminate some of the serious flaws in the products.There are many low-quality products on the markets that do not meet the requirements of energy saving and environmental safety. Products of iconic manufacturers are good in most indicators, but they are expensive. Under these conditions, the repair of energy-saving lamps with their own hands retains its relevance.
Types of ECL
Energy saving lamps for household use are divided into three types:
- Fluorescent. The most common electrical appliances. They are tubular, annular and compact. Discharge light sources. They contain inert gas with a small amount of mercury.
- Halogen. An improved version of incandescent bulbs. The spectrum of light is identical to the sun. By ECL are conditional. Energy savings are only twice as high as incandescent bulbs. Heat dissipation is high.
Before you repair the energy-saving lamp 9 w do it yourself, consider their device. Fluorescent energy-saving lamps have an identical device. Structurally, they consist of a gas-discharge tube, a housing, a base, a start-up unit and a power supply (electromagnetic ballast).
Starting control device - a pulse voltage converter from 220 W to 400 W. The gas-discharge tube is called an ECL bulb. It is sealed on both sides. Contains electrodes, mercury vapor in an inert gas. Mercury gives a glow under the influence of electric current. Spiral or arc-shaped tube types are designed to give the product a compact shape.
The flask is connected to the body. It is made of non-combustible polymer composites. It houses an electronic circuit (printed circuit board) of a high-frequency converter, a fuse, connecting wires, control gears. Base - standard element. The structure and size of the product is identical to those used in incandescent lamps.
Malfunctions of fluorescent lamps are mainly related to electronics. Parsing products is aimed at gaining access to the printed circuit board and electromagnetic ballast. Dismantling of the device begins with its external inspection. There may be mechanical damage and cracks. If you make a little effort, the structure will collapse without the possibility of recovery.
The separation of the flask from the body is not difficult. Fastening of two parts is carried out by means of latches installed inside the case. Access is convenient with a suitable screwdriver size. The process requires accuracy and attention. Hurry or excessive efforts in the separation of elements will lead to the breakage of the wires, which will significantly complicate further work. If the lamp is used for a long time, then due to the drying of the plastic, the latches may lose their elasticity. Open mechanically they will not succeed. The body will have to destroy the disk cutter of a small size or in another way.
There are options for saving the case. To do this, you need to make a cutter on it a few cuts and gently open the formed petals. The flask will easily detach. Upon completion of the work, all parts of the case are restored in their original form with the help of glue.
This disassembly step will open access to the electronic board unit. It is connected to the discharge tube and the base. A printed circuit board is a regulating and starting device. Replaces outdated starters and chokes.The board is connected to the discharge tube and the base in the flask with the help of wires. Without their rupture with the electronic circuit, further repair of energy-saving lamps with their own hands is almost impossible. They can be separated from the base by soldering or cutting. In both cases, they should be reset to their original state after lamp troubleshooting. Round board - the desired component for further work.
Repair of ECL
Repair energy-saving lamps with their own hands begins with finding out the causes of damage to the device. As a rule, there are two of them: a malfunction of the electronic circuit or the filament spiral. Most often they burn out. A comprehensive visual inspection of the board often allows you to identify damaged items that need to be replaced. The process of researching electronics begins with a fuse. It is soldered to the base contact of the base and the board. It is insulated from the rest of the parts with a special dielectric material.
Since the lamps cease to function due to increased energy loads, including short circuits, it is the fuses that first burn out, breaking the electrical circuit.The element is checked using a multimeter. In the absence of a gap in the element, a similar study is carried out in a resistor. Finding a fault in one of these elements, fix it. To do this, have a snack connecting wires.
The next test component is a flask. The dial determines the resistance of the filaments. To do this, they unsolder on each side. If the resistance in each of the filaments is nominal (about 10 ohms), then they are intact. With the burning of incandescent elements, repairing energy-saving lamps is not easy. We'll have to hold a new thread with the desired resistance indicator. At home it is not always possible.
They are related to semiconductor testing. Of them are made diodes, transistors, stabilizers. They are most sensitive to overload. The advantage of diodes and stabilizers is that their dialing can be made directly at the place of installation without a tap. Defective parts can be replaced by purchased radio stores. Having in the lamp transistors (there are two) to be unsoldered.Without this, it is impossible to check their health.
Similar diagnostics are made for resistors and capacitors. Practice shows that when replacing even a significant part of semiconductor elements, repairing energy-saving lamps with your own hands will be cheaper than buying a new lamp. If you collect the product from 3-5 defective devices, the savings will be significant.
Repair ECL Zeon
The Chinese manufacturer of luminescent elements Zeon in recent years has noticeably deteriorated the quality of the products offered. Products rarely withstand the stated operational life of 8000 hours. Do-it-yourself Zeon energy-saving lamp repair is becoming commonplace. It does not differ from the removal of faults in other ECL. However, the peculiarity of Chinese products lies in the possibility of replacing most wiring products with more advanced domestic and foreign products. In particular, widely used in D226B lamps are replaced by silicon diodes with a current of 0.3 A.
Instead of Chinese capacitors, Russian analogues (IHL) are used. They operate at voltages above 400 W. R1 resistors correspond to MLT analogs.Nichrome wire is chosen so long that the resistance corresponds to the nominal value of the original. All electronic elements of lamp construction are commercially available. The practice of repairing energy-saving lamps from a Chinese company shows that resource indicators can be increased by 20 percent. There are examples of increasing the working period to 10,000 hours, which is higher than the parameter from the manufacturer Zeon itself.
Repair ESL Maxus
Another famous Chinese product is ECL Maxus. In general, products manufactured by the company are of high quality and are popular. Do-it-yourself repair of energy saving Maxus lamps is complicated by one feature that has a technological nature. When the load rises above the critical values, the paint, with the help of which the parts are marked, melts and falls on the board track. The basis of the latter is textolite. He is in short-circuit places fade. Both faults lead to breakdown circuits.
How to repair energy-saving lamps with their own hands? Schemes to recover is quite possible. The problem can be easily solved by simply removing the paint with a sharp object.Then the resistance will tend to infinity. However, finding a place of damage is extremely difficult. In some cases, for this it is necessary to do a tap-off of all conductors.
Do-it-yourself energy-saving lamp repair (20W)
It has no fundamental differences from other lamps. The exceptions are cases when the connecting wire of the board and the case is presented in the form of a thin wire wound on a resistor. When cutting, care must be taken not to disrupt the design nominal resistance. Otherwise, inevitable power surges in the structure with the destruction of individual elements. So, we figured out how to repair energy-saving lamps. The instructions will help you to restore the old item.
