LIGHTING ARRANGEMENT

摘要

The invention describes a low-power load arrangement (1) comprising a low-power load (3); a driver (2) for the low-power load (3); connectors (300) for connecting to an electronic transformer (2) realised for converting a mains power supply (4) to a power supply for a normal-power load (5); and a reverse current generating means (LP, SB) realised to provide a reverse current (Irev LP, Irev SB) to sustain self-oscillation during operation of the electronic transformer (2), wherein the direction of current flow of the reverse current (Irev_LP, Irev_SB) is opposite in direction to the output current of the electronic transformer (2). The invention further describes a lighting arrangement (1) comprising an electronic transformer (2) realised for converting a mains power supply (4) to a power supply for a normal-power load; a low-power load (3) connected to the electronic transformer (2), which low-power load (3) comprises a low-power light source (30); and wherein the lighting arrangement (1) comprises a reverse current generating means (LP, SB) realised to provide a reverse current (Irev_LP, Irev_SB) to sustain transformer self-oscillation when the transformer (2) drives the low-power load (3), wherein the direction of current flow of the reverse current (Irev_LP, Irev_SB) is opposite in direction to the output current of the electronic transformer (2). The invention also describes a method of driving a low-power load (3) with an electronic transformer (2) realised for driving a normal-power load (5).
