Energy-efficient lighting system

摘要: The invention relates to a method for improving energy efficiency in lighting system having at least one light source ( 3 ), wherein the ) can be connected an external electrical source, example grid, power supply purposes via operating device 2 ). In order avoid standby losses which arise when needs grid even inactive state generate necessary runup semiconductor IC 8 switch-on command arrives bus, it is proposed that additional recovered from not used or direct indirect neighbouring luminaires ); ambient by means of photovoltaic conversion and supplied as this way, isolated during state.
