Abstract
A LED driving arrangement constituted of: a control circuitry; an inductance element having a primary side and a secondary side; the inductance element arranged, responsive to a switching circuit, to receive power at the primary side from a power source, and the inductance element further arranged, responsive to the received power at the primary side, to output at the secondary side a function of the received power; at least LED based luminaire; a parasitic capacitance between the at least one LED based luminaire and a chassis; and an electronically controlled switch coupled between the secondary side of the inductance element and the at least one LED based luminaire, wherein the electronically controlled switch and the secondary side of the inductance element and a discharge path of the parasitic capacitance are coupled in series.
