Hi..
In my 220VAC LED lamp 40W the driver suddenly stopped working, after inspection i found out that the capacitor 400v 15uf was burned. The part of the circuit is like 220VAC input -->4 diodes ---> to 400v 15uf cap. and then the rest of the circuit which i do not understand but looks very simple with very few parts and very compact. something like attached image.
I replaced it with a 400v 10uf capacitor which i took from an old circuit which by dimension is bigger. My lamp is working again with same amount of light i do not notice any difference. SO the question is why/how.
