DRIVER DEVICE FOR LEDS

摘要

The present invention relates to a driver device (10) for driving and controlling light emitting diodes (LEDs) or LED-strings comprising a control unit (16), and at least two switching units (14) coupled in series, and each comprising a switch (22) controllable by said control unit (16) and two connection points (30) for connecting at least one LED, wherein the first connection point (28) is coupled with one end of said switch (22). The driver device is characterized in that each switching unit (14.1 to 14.n) comprises an inductance coupled between the other end of said switch (22) and said second connection point (30).
