Method for driving LED-lamp of electrical system of e.g. commercial vehicle, involves providing measured flow current as control value to booster, and regulating additional load by measured flow current that is supplied to battery

摘要

The method involves flowing current to a LED, and measuring flow of the current by a total current meter (1). The measured flow current is provided as a control value to a direct current/ direct current booster (3) e.g. boost-converter, and an additional load is regulated by the measured flow current. The measured flow current is supplied to a battery, and multiple outputs of a lamp control unit (2) are controlled over the booster. The additional load is parallely simulated to a LED-lamp of an electrical system.
