Often heard that now the LED lamps and lanterns is short life is mainly the power of life is short, and the power are shorter because electrolytic capacitor life short. They also have a point. Inferior because the market is filled with a lot of short life of electrolytic capacitors, plus spell the price now, so some manufacturer regardless of the quality and inferior to adopt the short life of electrolytic capacitors, the result is the conclusion.
So what on earth is the actual situation?
1. The service life of electrolytic capacitor depends on the ambient temperature when it works
The life of the electrolytic capacitor is how to define? Of course is hours definition. But if the life index of an electrolytic capacitor is 1000 hours, not after 1000 hours, the electrolytic capacitor is bad, no, I just said that the electrolytic capacitor capacity after 1000 hours capacity reduced half, was 20 uf, only 10 uf now.
There is nothing wrong with short wash time LED life electrolytic capacitor
In addition, the service life of electrolytic capacitor index has a characteristic, how many degrees is must in the life of the working environment temperature circumstances. And are often prescribed for the life of the under 105 ℃ environment temperature.
This is because we are now commonly used electrolytic capacitors are used liquid electrolyte capacitors, if the electrolyte dry, electric capacity, of course not. The higher the temperature, the easier it is to electrolyte evaporation. So the service life of electrolytic capacitor index must indicate what is in the life of the ambient temperature.
