And what is limiting the LED current? BTW, a LED does not have back EMF.

resistor limiting current to LED. you can replace LED with lamp, work similar but need to change resistor

And when the temperatur increases and the Hfe (the DC current gain factor) does also, the LED does burn?

I'm not sure that I got you right, but I don't think so

Ok, another question, you have an idea which transistor you are going to use for a real implementation?

Looks like you have no idea.
