LIGHT EMITTING DIODE DRIVER WITH DIFFERENTIAL VOLTAGE SUPPLY

摘要

The current invention relates to a driver for driving one or a plurality of LEDs (D1, D2), comprising at least one driving unit (201, 202) adapted to be supplied with a differential voltage, between one first bias voltage (VB1) and one second bias voltage (VB2), the differential voltage being adapted to be equal or larger than the largest expected variations (ΔVF) of the forward voltage of said one or a plurality of LEDs (D1, D2). Another aspect of the invention relates to an integrated package comprising at least an LED and associated driving unit (201, 202). Another aspect of the invention relates to a light module comprising a plurality of LEDs (D1, D2) and associated driving units (201, 202).
