    There are calculator sites that will show you how, you will need the led specs and it will show you the series and parallel of the circuit.

    Thanks for taking time and replying Jotto and BobK

    I used the ledcalculator . I've got the schematic to build it .But is there any specification in the 12v source or any 12v adaptor will do job ?

    It needs to supply 12V and the current needs to be at least that which your load will draw preferably more, to give it some safety margin)
