4 reasons why LED bulbs burn out quickly

Since the appearance of LED lamps, manufacturers have positioned them as one of the most reliable. They last longer than others and save energy. The prices of such lamps are justified by the performance characteristics. If the LED bulb has burned out several times or faster than stated in the warranty card, you should look for the causes.

LED bulbs consist of a matrix with a large number of LEDs, and the assembly is covered by a solid bulb. Sometimes the cause of burnout is a defect. But more often the problems are related to wiring or unstable voltage in the network.

№1. Poor quality bulb

The most common cause of burnout - poor quality assembly and cheap materials. In order not to run into a fake, you should not pay attention to the Chinese brands, which have a low price, but do not guarantee quality. During the first days of use the lamp can burn brightly, and lamps are often distinguished by tempting design, but these are the only advantages of Chinese products.

The structure of the LED lamp.

The main reason why a cheap light bulb burns out is the lack of driverThat stabilizes the voltage fluctuations. Its presence is important when installing the lamp in a ceiling chandelier. If it has LED backlighting, a current regulator is usually installed. The output voltage it is designed for varies over a wide range. The output current value will remain constant.

Brands to look out for when looking for a quality light bulb:

• Eurolamp;
• Lemanso;
• Feron;
• Philips;
• Osram;
• Lexman;
• Voltega;
• Maxus.

Since Chinese manufacturers are trying to save money and earn more, they install a ballast power supply instead of a driver. Its main disadvantage is is the lack of current stabilization functionwhich often causes lamps to burn out.

№2. Defects in the electrical wiring

To understand why LEDs in light bulbs often burn out, you can go to an electrician to check the wiring. You should also pay attention to the condition of the sockets in the chandelier. If a lamp often burns out in the same room, the problem is in the wiring. The first thing to check is the connection of the wires in the junction box.

Example of a proper connection of wires in a junction box.

Experts also advise checking the connection of the ceiling light. If after checking it turns out that the wiring is okay, but the diodes have not stopped burning out, check the sockets. If they are burned or destroyed, they need to be replaced. Sometimes a little repairing. To do this, it is enough to grind the contacts and bend them to their original positions.

№3. Instability of voltage in the network

LED bulb burnout due to problems with voltage instability is common in suburban homes. The surge can occur at a time of peak power consumption. If a lamp without a driver is installed in the chandelier, it is likely to burn out.

Measure instability and influence parameters.

Voltage surge in the house or apartment can overcome only a quality lamp with the presence of a driver with a wide range. In most expensive bulbs, it ranges from 160 V to 235 V. But if the bulbs burn out from popular and expensive manufacturers, the only solution is to buy a voltage regulator.

№4. Frequent switching on and off

If you can not understand the cause of the failure of the lamp, it makes sense to think about more trivial things. One of them is the constant switching on and off. It is worth paying attention to switches that are equipped with a display. In order to be able to adjust the current to save energy, the switches are equipped with dimmer. Before selecting a lamp for it, you should ask the consultant if it will work correctly.

The marking of the dimmable lamp.

If there is a sign on the package, as shown in the picture above, the bulb can be installed in a chandelier, the light intensity of which is regulated by the switch. If you purchase a non-dimmable bulb, because of the current that passes through it even when it is turned off, it will soon burn out.

The effect of frequent switching on and off on the life of LED lamps has not been proven. Most experts believe that it can not cause burnout due to the lack of starting electronics in the design.

Other causes

Intensive use does not affect the life of the bulb. In the instructions, you can find information that the number of turns on is not limited. But this applies only to expensive brands. Chinese manufacturers can not boast of such a feature. Therefore, a cheap bulb can burn out. due to frequent use.

The video describes a way to improve the LED lamp.

Defects in the chandelier can also provoke combustion. To avoid encountering such a problem, when choosing a chandelier, you should pay attention to:

• lighting area;
• the quality of the socket;
• service life;
• manufacturing material;
• the ability to adjust the brightness of the light;
• power stability, which will affect the period of operation.

If the bulb burns out often and the cause is not found, you should buy and install a voltage converter.

Another 4 main reasons are described in the video.

To determine the type of converter, ask for help from an electrician. If ice. bulbs in spotlights burn out constantly, the lack of a converter is not the only cause of the problem. It is often due to a poor quality power supply, insufficient power or improper power supply circuitry of the lights.
