Why are LED lights on so often?

LED lighting has already taken over the entire market and it is less and less likely to find people who have LED lamps are installed instead of incandescent or halogen (or fluorescent) lamps lamps.

But, despite all the assurances from marketers that Led lamps work for decades, they fail with unpleasant regularity and we have to buy more and more. In this article I will try to explain the reasons for this process and how to avoid it. So, let's begin.

Because of what LED lamps often burn out

In my opinion, there are three main causes of LED lamp burnout, accounting for 99 failures in 100. And the first of the main reasons is the excess of the LED operating voltage.

Most LEDs work (light up) when a constant voltage of 1.5 - 3 volts is applied to their electrodes. The magnitude of the voltage depends on the type of semiconductor used. So, if you exceed the value of this voltage, the LED will fail very quickly.

To prevent this from happening, manufacturers install overvoltage protection circuits that prevent voltage surges in the network from affecting the LEDs.

But if a fake or a low-quality product is bought, then it may simply not have such protection and absolutely any voltage surge will damage the lamp. And you will have to go and buy a new one, spending your hard-earned money.

Another reason for the frequent burnout of LED lamps is overheating. Indeed, despite the declared high efficiency and productivity, only about one third of the consumed energy is converted into light on LEDs, the remaining two thirds are spent on heating. And this heat needs to be put somewhere.

In high-quality lamps, this problem is solved by the installed radiator, which dissipates heat and ensures a normal operating temperature. But again, if you take a cheap sample, in which there is a weak radiator or the radiator is completely absent, then such a lamp is unlikely to work even for one year.

And the third reason why lamps fail is again the desire of manufacturers to save as much as possible on production and a deliberate overestimation of the operating current of LEDs. As a result of this "savings", you can install fewer LEDs that will work to their limit.

But as a result of such "economy", the LEDs in such a lamp may not survive the most dangerous period during operation - the moment of switching on. And the initial impulse of current will simply disable them.

So what should ordinary consumers do?

No, I will not say that you need to buy the most expensive lamps, as well-known brands are very often counterfeited. But there is a way out: to buy lamps in trusted stores (do not order them on foreign portals, where you cannot will provide no guarantee), where you will be provided with a warranty for the product and it is imperative to keep receipts and boxes from lamps.

Thus, you will protect yourself from unnecessary expenses for at least 2 years (usually this is the warranty period for lamps) and if during this time, the lamp will stop working, then you simply change it to a new one in the store without any costs.
