<p>A lighting system comprising a driving circuitry connectable to a lighting apparatus, where the driving circuitry comprises a constant current source for powering the lighting apparatus and a stabilizing circuitry electrically coupled to the constant current source for adjusting the voltage over the constant current source. The stabilizing circuitry may comprise at least one capacitive element and a controlled current source operable for controllably charging the at least one capacitive element so as to maintain a substantially constant electrical power supply of the lighting apparatus.</p> |
