5. Protect the electrolytic capacitor
Sometimes even if long life electrolytic capacitors are used, but will often find electrolytic capacitor is broken, what reason is this?
Actually if you think this is the quality of electrolytic capacitor does not pass, that is really make in time to the electrolytic capacitor! In fact, electrolytic capacitor is not perpetrators, but the victim. Why do you say so?
Because we know that in the mains ac online, often instantaneous high pressure generated by lightning surge, while on the large power grid for lightning have done a lot of lightning protection lightning protection measures, but inevitably there will be still leaking through the net to residents’ home. Power grid should be very advanced in the United States, but one thing happened in my home, after a lightning strike, I found my fax machine doesn’t work, after carefully check, original because the power to be struck by lightning and completely broke, can only be scrapped.
If it is from the mains power supply for LED lamps and lanterns, so in the power of the lamps and lanterns must in mains input and surge prevention measures, including the fuse, resistance and over-voltage protection, often referred to as pressure sensitive resistance, to protect the back of the components, again long life electrolytic capacitors can also be breakdown by surge voltage.
I believe that if all the LED manufacturers can adopt normal electrolytic capacitors with high quality, and adopted the above relevant measures, then the electrolytic capacitor of time will be able to get clean!
