i need circuit ( schematic ) for tube light choke

 

I think you need to explain clearly just what a 'tube light choke' is.

 

What are we supposed to vote for?

 

Try Google "fluorescent lamp ballast".

i need a software to draw schematic by watching an actual circuit

I think you need to explain clearly just what a 'tube light choke' is.

The main function of Choke in tube light ckt is to boosting the voltage level & starter has nothing but a simple bi metallic strip inside which closes & opens the ckt.when we switch the ckt current flow in side Choke,starter & tube filament.when the voltage level increase nearly 10 time the normal voltage its heat the filament .as a result current passes through tube light directly with the help of argon gas & starter is automatically cut off from ckt

That would be very useful! All you'd need to do would be photograph top and bottom of a populated PCB, import the images into the software, let it reverse-engineer the circuit, then spit out a schematic. If you can identify a source of this software I'd be interested to know.
Or have I misunderstood your requirement?
