Abstract

A lighting system for operation with a dimmer circuit (1) comprising a triac (TR1) connected to a load. The load comprises a driver circuit for supplying current to a light source comprising one or more LEDs (LED 1-4), the current being determined at least in part by an adjusted setpoint value. The system further comprises a setpoint filter circuit (20) for obtaining a dimmer setpoint value (21) determined at least in part by a setting of the dimmer circuit (1), and for generating an adjusted setpoint value (24). The sensitivity of the adjusted setpoint value to changes in the dimmer setpoint value is low at low values of the dimmer setpoint value.
