Lamps, like other electrical appliances, have a lifetime and cannot stay healthy and bright all the time. Although the LED lamp has significant advantages, one of the main reasons for its popularity is its long life. The lifespan of a quality LED lamp should not be less than 15,000 hours. Extending the life of LED lamps is one of the concerns of the manufacturers of these products. LED lamps have a longer lifespan than incandescent lamps. But this is not always true and sometimes LED lamps burn out sooner than we expect.
The cause of the burning of the LED lamp
1) High voltage electric current
The voltage range of municipal electricity in Iran is 220 V AC with a frequency of 50 Hz, and most of the lighting equipment, including household lamps, with These voltages work. A 5% change in these values will not cause a problem in the lighting equipment, but more than that will be problematic. If the electrical voltage in your house is very high, the lamps will turn on anyway, but they will have a shorter life and this voltage is more than the lamp can withstand, causing the lamp to turn on with intense light, which causes the lamp to burn.
It doesn't matter what kind of lamp or fixture you install the lamp on, if the lamp is in a position where it vibrates a lot, it will burn out very quickly. This problem is mostly seen in chandelier ceiling fans and door lamps that are not well installed. When the fan blades are unbalanced, the fan starts to vibrate and this vibration is transmitted to the lamp. To prevent this problem, the fan needs to be serviced again. In general, excessive vibration and movement in the lamp leads to a decrease in its life. Compared to old lamps, LED lamps are more resistant to vibration.
3) Failure of the lamp screw
Problems that arise in the lamp screw are another reason for the lamp to burn and not light up. It is good to know that there is a small metal tab inside the screw head of each lamp, whose task is to establish a connection with the metal at the end of the lamp, and through this connection, electric current is transferred to the lamp. When the small metal tab at the bottom of the socket is pushed down too much, it cuts off the electricity inside the lamp, and as a result, the lamp does not turn on, and you think the lamp is burnt out, when the problem is with the lamp head.
4) Burning of the lamp due to the loosening of the screw head
One of the reasons for the lamp not turning on is the looseness of the lamp in the screw head. If the bulb is not fully secured in the cap, it can cause the bulb to flicker or short, which will eventually cause the bulb to burn out. Of course, the wires connected to the lamp or the screw may also have a problem, in this case the lamp will not turn on and if there is a connection wire, it will burn quickly.
5) Electric fuse jump >
It is good to know that cutting off or jumping the fuse is one of the most important reasons for burning the lamp. In case of power failure, the lamps are turned off by the fuse. Jumping the fuse can be due to the connection of electrical appliances, problems in wiring and connections, which may lead to the burning of lamps and other devices connected to electricity.
Strategies to extend the life of the lamp
To increase the life of the lamp, we must consider various points when buying and using the lamp. Extending the life of the LED lamp depends on following very simple tips. Using reputable brands can help in this regard. The cause of burning LED lamp or any other type of lamp can depend on the mentioned reasons. In the following, we will explain some tips to increase the life of the lamp: - Ensuring the validity of the lamp brand - Preventing mechanical shocks - Proper temperature of the environment and reducing the number of times it is turned off. and turn it on
- avoid voltage fluctuations
- do not install the lamp incorrectly
- make sure there is no wiring problem
- avoid installing it in a closed space
- use low consumption models< br>- Purchase of LED lamps with warranty
