The main causes of degradation of LEDs

When buying LED bulbs, we hope that it will shine for a long time and will last the claimed life. Unfortunately, after a while, many notice that the light begins to shine in a different way or do not work. In this article I will discuss the main causes of degradation of LEDs. So, let's begin.

Exceeding the amperage

Claimed battery LEDs can reach 50 000 - 100 thousand hours continuous operation. Agree, this is a very long time, about on the condition that the current consumption is less than 20mA.

But in order to save on production, Chinese manufacturers have set in place a quality LED, LED is used to illuminate the screens of mobile devices, as they are much cheaper. Their consumption current is 5 mA.

At a current of 20 mA they continue to work, but their life is greatly reduced and the luminous intensity is also changed.

heat release

In operation, the LED emits heat and for its removal from the super-bright diodes need to use appropriate modern platform. But manufacturers are again used to save the old body diodes that are not designed to increased heat, which leads to overheating of the crystal, which in turn shortens the lifespan LEDs.

Poor quality crystals

Perhaps the main reason for LED degradation is the use of low-quality chips. Some companies still buy chips produced by Nichia first-generation technology with a transparent p - contact.

This is the cheapest in the technology industry, mainly used in mobile devices. It is also often the production of mediocre monitor the quality of the process, which also does not add to safety produced by the LED.

careless assembly

The basic principle of the manufacturer - the main quantity, rather than quality, inevitably puts its mark on the quality of the collected of LED lamps. And at first collected in such a way LED light does not yield quite high quality, but expensive competitors.

But after you buy this cheap LED lamp, it will not serve even half of the declared period.

misuse

And another reason for LED degradation is the improper use of the finished product (refers to the LED strip). Even the cheapest LED ribbon, purchased in China, it will last you a long time, if you think over the removal of heat.

For example, if you attach the tape to the aluminum profile, the generated heat is dissipated quite successfully in space, and thermal overheating is excluded.

conclusion

These are all major causes of degradation of LEDs. In order to best protect themselves from such substandard products, purchase LED bulb with a guarantee only. This allows you to completely safely exchange the lamp which appeared on a new charge.
