Hi everyone, I'm making a house model in which I use one VAC bulb and another one but uses DC source. What blocking me at the moment is the electric source of the VDC bulb. I want to use circle in phone charger (I have many of them, ones of Nokia 12xx) to transform VAC into VDC and I tried but it seems no results. I'm neither a pure electrician nor majoring in electrics. So hope that you can raise your voice and help me.
 
A cellphone charger does not just act like a normal transformer with a rectifier. It has sensing circuitry that constantly monitors the load (usually the battery) and adjusts its output automatically. It's possible it doesn't recognize the characteristics of your LED and is going into standby mode.

It might work if you include an old Nokia cellphone battery in the circuit but you would probably be better using an LED driver or even normal AA batteries of the correct DC voltage without a charger.
