Abstract

A method for configuring an LED, Light Emitting Diode, driver (100) for dimming of an LED (10), the LED driver (100) being arranged to provide a variable current which is modulated, using a transistor of the LED driver (100), based on a binary control signal having an instantaneous time-averaged value as time-averaged, the method comprising the stepsproviding the variable current with several different instantaneous time-averaged values; obtaining, for each of the several different instantaneous time-averaged values, a respective measurement value of an average current flowing through the LED (10) or the load (20) or an average light intensity emitted by the LED (10), thereby obtaining a measured first relationship; based on the first relationship, determining configuration information regarding a mapping of each of several different absolute or relative current/light intensity values to a corresponding value for the instantaneous time-averaged value; andstoring the configuration information.
