Abstract
The invention describes a low-power load arrangement () comprising a low-power load (); a driver () for the low-power load (); connectors () for connecting to an electronic transformer () realized for converting a mains power supply () to a power supply for a normal-power load (); and a reverse current generating means (L, SB) realized to provide a reverse current (I, I) to sustain self-oscillation during operation of the electronic transformer (), wherein the direction of current flow of the reverse current (I, I) is opposite in direction to the output current of the electronic transformer (). The invention further describes a lighting arrangement () comprising an electronic transformer () realized for converting a mains power supply () to a power supply for a normal-power load; a low-power load () connected to the electronic transformer (), which low-power load () comprises a low-power light source (); and wherein the lighting arrangement () comprises a reverse current generating means (L, SB) realized to provide a reverse current (I, I) to sustain transformer self-oscillation when the transformer () drives the low-power load (), wherein the direction of current flow of the reverse current (I, I) is opposite in direction to the output current of the electronic transformer (). The invention also describes a method of driving a low-power load () with an electronic transformer () realized for driving a normal-power load ().
