Low-quality products of
Unfortunately, the main reason for LED burnout is poor build quality. In the search for cheap LED products, we often fall for the trick of Chinese brands - bright light bulbs, which, as an advertisement, shine fairly well on the stand and yet have a stylish design. The fact is that most of the LED products from China are manufactured in such a low-cost version that the bulbs burn out due to the lack of protection elements for the LEDs from current surges in the driver circuit. As a result - when the voltage jumps in the current increases, because of which the LEDs are heated above the nominal temperature and, of course, burn out.
In addition, we will return to another reason, which is closely related to the advertising move when demonstrating the glow of a light bulb on the stand. When choosing a LED lamp for the house, we all try to find an option that will shine well and at the same time cost cheap. That's why some manufacturers pick up resistors and capacitors in the bulbs in such a way that the LEDs work at full power, but bright. As a result, the service life of the products is rapidly reduced and they burn.
Another reason for the frequent burning of LED lamps is the defect in the configuration and the breakdown of soldering technology, which is typical of cheap Chinese products.
If you are sure that the bulbs in the chandelier are of high quality and they burn out only in one room, for example, in the bathroom, most likely the reasonin the wiring. First of all check the quality of the wire connection in the junction box, from which the wires to the switch and the chandelier go. In addition, check the connection of the ceiling light. There should be no twists and all the more bared connections, as in the photo below. It is recommended to connect the wires with special WAGO terminal blocks.
If the wiring is correct, but the LEDs burn out, check the chucks in the chandelier. They should not be burnt or completely destroyed. If the case in the cartridge, you can try to restore it - clean and bend the contacts. Otherwise it is necessary to replace the cartridge in the chandelier with a new one.
We have provided the 2 most important reasons for the burnout of LED lamps. If it's not a matter of quality, then it's likely that the wiring will soon be over, and vice versa. If you are sure that the light bulb and wiring are not the culprits, then you can check a few more points, which we described below.
What else could it be?
When we considered the technical characteristics of LED lamps, we pointed to a parameter such as the number of inclusions. In LED bulbs, as a rule, the number of inclusions declared by the manufacturer is unlimited. But in practice, the frequent switching on of light affects the life of the LEDs and if you use the light switch in the room tens of times a day, it may well be that the lamps burn out for this reason, especially if they are Chinese.
Here you should also talk about the switches with illumination. If the chandelier is controlled by such a switch, then most likely you noticed that the LED light bulb sometimes flickers or generally dimly lit when the light is off. In most cases, the LEDs are incompatible with switches with backlighting, so if they are used for a long time, they can burn out. Solve the problem by simply turning off the light on the switch.
Well, the last, rarely encountered situation is when the 12 volts LEDs burn in spotlights. Here, the situation may be either in the wrong scheme for connecting the backlight, or in the power supply( incorrectly selected power or poor quality).The correct schemes for connecting the spotlights we provided. As for the power supply, it should be selected with a power reserve( at least 20%).
We draw your attention to the fact that sometimes the owners of apartments think that they have blown out all the LED lamps with 12 volts in the stretch ceiling. The first step is to check the power supply,most likely, he burned, not the light bulb!
That's actually all the reasons for the LED products burnout. We hope that our information was useful to you and now you know why the LED lamps burn out, and what to do in this case! We draw your attention to the important nuance - each lamp has its own warranty period, so if in your case, the burnout occurred immediately after purchase due to poor build quality - you can safely go where you bought and solve this problem with the seller!
