LED technology explanation: electrolytic capacitor will lead to the LED lamp life expectancy?

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 its temperature at work 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 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. 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. So now all electrolytic capacitors are marked the life of the under 105 ℃. Such as the most common electrolytic capacitor, life is only 1000 hours at 105 ℃. But if think that all the life of the electrolytic capacitor is only 1000 hours. It would be wrong. Simply put, if the environment temperature is higher than 105 ℃, then its life will be less than 1000 hours, if the environment temperature is below 105 ℃, then its life span is more than 1000 hours. The life and have a general quantitative relationship between temperature? Some! A most simple and easy to calculate, the relationship between environmental temperature rise every 10 degrees, life is lower half; On the other hand, every 10 degrees below the environment temperature, life is doubled. This is just a simple estimate, of course, but also be quite accurate. For surely used in electrolytic capacitor of LED drive power supply, is the inside of the shell on the LED lamps and lanterns, so we need to know the temperature inside the LED lamps and lanterns can know the working life of the electrolytic capacitor.
