Abstract (en)
[origin: WO2009052868A1] The invention provides an electronic ballast with a control ASIC which allows a discharge lamp to be dimmed. A switch connects or disconnects a mains connection which controls a transistor which connects or disconnects a resistor, so that the potential at a control input of the control ASIC changes.
