Hi Nohammed Saad The same circuit can be used if it is mains operated LED appeared on Circuits today. If it is DC operated then you can use a variable current source using LM317 or MOSFET.

This circuit diagram is very popular and useful. But I have another one with An optional 7-segment display with its associated circuitry has been provided to display your choice of fan speed.http://circuitsector.blogspot.com/2010/12/digital-fan-regulator-circuit.html
