Repair of LED lamps with their hands: step by step guide

Even a decade ago, it was not meant as a rapid rise in popularity LED lighting apartments and private houses. Today, you will not meet a man who would not use these economical and bright lamps. The problem is only in the cost of lighting - such cheap lamps can not be called. What do you do when the lamp is out of order? Purchase a new one? Not necessary. You can try to repair the lighting fixture. It is the "instrument", because it is a complicated technical device, in contrast to the "light bulb Ilyich." Today, we look at how to repair the LED lamps with their hands and how hard it is.

The principle of operation of LED lamps

LEDs They are the most economical type of lighting - it's hard to argue. Apply such elements and at home and at work. street lighting gradually moving to a similar energy savings. Light emitting diodes, in addition to efficiency, have another huge advantage over other types of lighting - on the durability of competitors do not have. But from the network to an alternating current of 220 V, they may not work directly. This requires special devices called driver.

Scheme LED lamp 220 include a device that is sufficiently compact and fits in the socket. More in lighting fixtures is no big deal, but the driver is performing the work on voltage stabilization, And often fails. Burned LEDs replace is not difficult enough to own soldering iron "Just learned" on the level. And here is how to repair the driver, we understand today.

The general principle of LED lamps is as follows. Alternating network current is supplied to the electronic device - driver, which stabilizes the voltage fluctuations. Direct current is directed to the light-emitting diodes, which emit visible light by us.

The simplest LED lamp circuit apparatus 220

If such a simplified system, we obtain the LED lamp driver circuit 220, which includes two damping resistors which stabilize voltage. LEDs connected in different directions, which protects against reverse voltage. flicker frequency increased by 2 times - from 50 to 100 Hz.

Power in this scheme passes through restrictive capacitor to the rectifier (diode bridge), and only then to the elements. Simplify the system. Changing one light diode rectifier. The lamp operates but the frequency of the current, instead of increasing, is reduced by 2 times and becomes equal to 25 Hz, which leads to chuvstvitelnomumertsaniyu lighting unit. It is harmful to vision, impairs health, increases fatigue and causes headaches.

The average cost of LED bulbs on the shelves of Russian

However, there are LED bulbs and a completely different value. For example, GENILED SOM-SCH 07077 80W 80 W and a color temperature of 4700K. Its price may surprise. It is 10 200 rubles.

Common causes of failures of LED lamps

Often the cause of failure LED lamps It becomes improper operation or sudden changes in voltage. Let us consider the most common:

• The sharp jump in the voltage. LEDs in such a situation will remain intact, but the driver may fail;
• Wrong choice of lamp. Unless proper ventilation is provided, the driver is overheated, which has a negative impact on its work;
• Factory marriage or falsified products. If the counter came across too cheap lamp this type, it is worth considering how the achieved low price;
• Vibration and shock. LEDs are not terrible, but for the drivers can be disastrous.

Most often it goes down the capacitor (light stops flashing), and the current-limiting resistor (delicate shimmer, until blinking). Not to buy new equipment, you need to figure out how to repair the LED lamp with your hands.

Repair of the LED lamp 220 in their own hands: step by step guide

Driver, becoming the cause of failure in 80% of cases, does not necessarily embedded in a light bulb. The light source may consist only of the LEDs, and the stabilizing device is built into the lamp, or chandelier. However, the remaining 20% ​​is not worth discounted. You need to check all the details before you start to repair the ice lamps.

In the case of individual drivers all the easier. Change the lamp, and, if it is lit, then the problem is in it, if not - to blame stabilizer. With built-in driver is more complicated.

	The first question - how to disassemble an LED light bulb. This is done easily. Turn the radiator counterclockwise.
	Removing the driver. We do not dwell on continuity LEDs - it is simple, but the electronics is "tricky".
	Here it can be seen the trouble spots, even visually, but to ring the diode bridge and chip stands. Around it notices that the driver experienced a sharp power surge.
	Soldering with SMD-components can not work - there is a danger of overheating the circuit board and the element itself, and therefore, have a hairdryer and soldering station. Such devices have not every master, so step by step instructions below we will open another secret of how to get around this problem with improvised means.
	Vypayat diode bridge and chip, we coat the contacts with a special paste and heated. It will subsequently put into place small parts and solder them carefully.
	We start with the chips. These parts can be purchased for 50 ÷ 70 RUB / 10 pcs in the Chinese online store. Gluing a chip on the paste, and solder adheres.
	Now, a diode bridge. He has a look like this, and sold on the same sites.
	Ready driver carefully solder first to the cap. Posting it is very short, and not to dismantle zavaltsovany on a plastic socket body, they need to build.
	Another driver side is soldered to the printed circuit board with LEDs. It is important not to reverse the polarity. PCB and driver pole marked.
	It remains to test the functionality. We apply power at the dismantled lamp. If you do not have experience of electrical work, do not - there is a risk of electric shock or short circuit.

Repair of LED lamps with their hands: work without soldering station

Now the promised secret. For renovation LED lamps conventional soldering iron is needed piece of copper stranded wire cross section 4 mm², length 10 ÷ 15 cm. Wind it over the soldering tip tight spiral so that the sting is extended by 4 ÷ 5 cm, and the end of the copper wire sharpened under "awl" or "blade". Will depend on the length and temperature. Conveniently, if the multimeter is a function of the thermometer. For LED SMD components, which are used in LED lampsWe need a temperature of 240 ÷ 260 ° C.

How to disassemble LED lamp, laminated with a sealant

Some devices are not so easy to understand. When you try to turn the upper part of it does not work? Then the solvent is useful. We collect it in a syringe and needle gently pass through the seam. Leave for 5 minutes, then repeat the operation. Usually 2 ÷ 3, lacks procedures. Gently rock the upper part of left and right turns. After removal of the stripping cap old sealant and degreasing the surface. If you plan to use lamps in a dry place, a new sealant do not need to apply.

Repair of LED lamps: the device and the electrical circuits of various devices

Figure out how to fix LED lamp at 220V, and it makes sense to deal with more complex devices, such as spotlights or lamps. Though much of a difference in the work there. Experts say that the repair LED spotlights even easier, because the drivers and components are larger. We join in this opinion. Only it seems that such devices are high-tech and complicated. In fact, having at hand the scheme (they are always kept in the technical documentation of the lighting device) to produce, for example, repair of the LED lamps is simple enough. The same continuity LED driver details. After - selection of suitable instead of burned.

Important information! If the LED is burned out and the hand is not suitable for replacement, you can slightly extend the life of the lighting device. Contact burnt member bridged between themselves, and the light illuminates again. But it is necessary to be prepared for the fact that after a short time it goes out again. Burns following a bridged LED. If you continue to install jumpers between maintenance periods will decrease exponentially.

Extinguished all the lights in the bathroom: Causes and Remedies

If all went out at the same time LED lighting bathroom, Should start small. Remove the switch cover and the check voltage supply. If everything is OK, then the problem power supply.

Bathroom - a room with high humidity, Which is unacceptable to use lighting to 220 volts. For this reason, set the power supply to 12 volts. The reason that has ceased to burn all the lights at once can be a failure of this device or the breakdown of the wiring that is hardly realistic. This unit will have to buy. Dismantling the old block look technical parameters, gain stabilizer, with the same characteristics and set in place.

Important! All work on the dismantling and installation of stabilizing the power supply are made only when de-energized. It is better to disable the automatic introduction. The only way to protect yourself from electrical shock.

Addressing the causes of blinking LED lamps

This is a common problem. Sometimes people refuse to replace conventional lighting in the apartment on the LED due to the fact that when the lights are blinking LEDs in the manner of a stroboscope. The reason for this one - light switch.

If it is, it passes through a certain amount of electricity, which has no effect on normal bulbs. But the driver of LED lighting products present a capacitor that has the ability to store electricity, and then hand him over. It then collects "bit by bit" this energy, and upon reaching a certain amount outputs it as a pulse to the LEDs.

To solve the problem can be very simple - Turning off the backlight on the switch. However, the flashing of the display on the key - it is a consequence. And what's the reason? There is also no difficulties. The reason is the improper connection of cartridges chandeliers. It is known that during the installation of incandescent lamps is zero on the thread of the cap, and the center of - phase. Blinking LEDs begin, if this order is disturbed and the wiring is done correctly.

Summing up

LED lighting is not to slow down the pace of growth of its popularity. But even with the price reduction for lighting devices based on them, they remain expensive. And why pay more when you can fix a light bulb or lamp with your hands. You do not even need to get the details. Just do not throw defective. Then two or three can gather one working.
