Claim:
1. A LED driving arrangement comprising: a control circuitry; an inductance element having a primary side and a secondary side; a switching circuit, said inductance element arranged, responsive to said switching circuit, to receive power at said primary side from a power source, and said inductance element further arranged, responsive to said received power at said primary side, to output at said secondary side a function of said received power; at least one light emitting diode (LED) based luminaire; a parasitic capacitance between the at least one LED based luminaire and a chassis; and an electronically controlled switch coupled between said secondary side of said inductance element and said at least one LED based luminaire, wherein said electronically controlled switch is arranged, responsive to said control circuitry, to alternately switch between an open state and a closed state, said at least one LED based luminaire arranged to receive said output power when said electronically controlled switch is in said closed state and not receive said output power when said electronically controlled switch is in said open state, and wherein said electronically controlled switch, said secondary side of said inductance element and a discharge path of said parasitic capacitance are coupled in series.
