Causes of frequent burnout of LED lamps and how to eliminate them

For a long time, the market was confidently captured by LED lamps, and on the shelves you can find products for every taste and budget. If an ordinary incandescent lamp burned out earlier, we, without hesitation, simply threw out the old lamp and bought a new one.

If an LED lamp stops working (especially one bought for decent money), then with such frequent replacement, you can "fly into the pipe." In this article I will talk about the main causes of failure of LED lamps and how to avoid it. So let's get started.

The main causes of failure and how to eliminate them

Poor contact and arcing of the wiring

If you have an old switch, a defective socket or poor-quality twisting, then this can cause frequent failure of LED lamps.

How to fix

Well, it's actually simple. We first carefully inspect the cartridge, if there are no traces of heating and carbon deposits, then move on (if there is, change the cartridge to a new one). By the same principle, we inspect the switch and check the twists in the junction boxes.

If the contacts and connections are normal, then you need to look for the reasons in another.

Note. All work related to electricity must be carried out with a sufficient level of knowledge or by professionals. Also, checking the contacts should be done only on disconnected equipment.

Illuminated switches

Yes, do not be surprised, sometimes the reason for the frequent failure of the light bulb itself can be the backlight of the switch. If you have such a switch, you probably noticed how the lamp barely glows when it is off and sometimes even blinks slightly.

This can also greatly reduce the resource of the lamp itself and lead to its rapid failure.

How to fix

In this case, there are several solutions to this problem: the simplest is to simply refuse the backlight and turn it off, or install another switch without backlight.

"Wrong" chandeliers and lamps

Also, a common reason for the failure of a light bulb is the chandelier itself or the sconce. The thing is that approximately only one third of the consumed energy goes to light, and two thirds is converted into heat and needs to be disposed of somewhere. After all, overheating of the crystal is unacceptable and leads to rapid degradation of the pn junction in the crystal and failure of the lamp.

Low-quality lamps are especially sensitive to overheating (about them a little later), but still you should not screw powerful lamps into so-called sealed lamps, which have a degree of protection IP 65 or higher.

For such luminaires, it is better to use low-power lamps of 5 watts maximum. Since they generate less heat during operation, which means that they heat up the entire structure as a whole less.

Well, now let's move on to the lamps themselves.

Poor quality LED lamps

Before that, it was mainly about indirect causes of lamp burnout, but now we will take a closer look at the products themselves.

If you believe the advertising, then the LEDs should burn for a very long time and in fact this is true, but provided that a stable power supply of the LED chain is provided.

So for the stable operation of one LED, a voltage of 1.5 to 3 Volts is usually required and a certain amount of current strength (the value of which can be found in the technical documentation).

So the main and, perhaps, the only reason for the frequent failure of the lamp itself is the burnout of the LED due to an increase in the maximum permissible current level.

So there can be several reasons for this increase at once, namely:

• Bad faith of the manufacturer.

In order to increase the brightness of the light bulb (and thereby increase its cost when using the cheapest LEDs), some manufacturers deliberately "lift" the current strength. Thus, transferring the LEDs in the lamp to emergency operation.

And now a small jump in the network is enough for the lamp to burn out.

• Low quality parts.

Also, the reason for the failure is a banal and at the same time total economy. You already know that the LED lamp also generates a lot of heat during operation. And if the manufacturer spared money for a high-quality radiator (and overheating leads to degradation and failure of LEDs), then this greatly reduces the life of the LED lamp.

In addition, they often save on the driver and instead of a full-fledged control board, they put an extremely simple circuit.

This also does not add reliability to the light bulb and leads to a quick burnout.

These are the reasons for the frequent burnout of LED lamps. And now I will say a couple of important words about how to protect yourself from all this.

Conclusions.

You already know what to do with indirect problems, but what to do if the reason is in the lamp itself? There is only one option, not to try to save money, but to buy high-quality LED lamps, and best of all in specialized stores, where you will be provided with a product warranty.

After all, most stores that value their reputation work with reliable suppliers and provide a guarantee for their goods (usually from one to two years). And if during this time the lamp burns out, then you can safely exchange it for a new one completely free of charge.
