Abstract

The invention describes an analog bleeder control arrangement () realized for use between a power supply () and a load (), which bleeder control arrangement () is realized to generate a bleeder activation signal (_on) to activate a bleeder () arranged between the power supply () and the load (), and wherein the bleeder activation signal (_on) is generated only upon detection of a phase-cut edge (LE, FE) on a voltage input signal (U). The invention further describes an LED lamp driver (), realized to drive a lighting load () comprising a number of LED light sources () and comprising such a bleeder control arrangement (). The invention also describes a lighting arrangement () comprising an LED lighting load (); a driver circuit () realized to drive the lighting load (); a bleeder () for providing compatibility between a dimmer () and the driver (); and such a bleeder control arrangement () realized to activate the bleeder () only upon detection of a phase-cut edge (LE, FE) on a power supply input signal (U).
