Abstract
A lighting driver is designed for driving an unknown lighting load and is based on a controlled DC driver, with a controlled output current. It is used in a first mode of operation to determine an operating current of the lighting load and in a second mode of operation to deliver a current to the lighting load in dependence the determined operating current, and optionally also in dependence on a dimming setting. In this way, the driver configures its output to the load based on an analysis of the current characteristics of the load, such as the maximum rated current.
