night lamp sample check

[rajaram04]

Hello sir
I found a night lamp white led high voltage operational circuit




is it okk ?

is there any possibility of increasing number of LED ?

Hi RajaRam,

You can search EDABoard threads for transformeless power supply designs.

hmm okk
actually what my aim is to increase current parameters for these supplies but i failed everywhere i visited . . well let c or may be its impossible

The current is mostly decided by the value of the capacitor. Please note the comments in your other thread about using a bridge rectifier to get higher brightness and the problems of using LEDs in parallel.

hm thats true , now i ve enough info here to proceed

now its time for the action

Be careful with mains voltage, transformeless circuits definitely is not for start in electronics.

Be very careful. I suggest you to skip such circuits.
