I purchased few simple LED lamps from market.They consume very less power but with a little problem, they are not durable enough. They only last a week or so. When I opened one of them It had this circuit.

The problem is that the Capacitor (100 uF 35V) in the circuit Pops Up (Bust) after continues use. I tried changing the damaged Cap. C2 to another value 100 uF 63 V, (Pls. note that I only changed the volt rating 35 to 63 not the uF rating i.e. 100 uF) but the LEDS didn't glow.

Can someone please suggest me the value of the Cap (or some other modification in the circuit), so that the lamp keeps on working without the Cap being busting, even after prolonged use.

I am open to all suggestions.

Thanks

 

Hello,

Direct mains powered things are not alowed here.
The possibility for lethal failure is there.

That is correct - only transformer isolated circuits do not present a lethal shock hazard.

No capacitor current limited circuit can be made safe.
