Lighting system with improved preheating of discharge lamps
The system has an electronic operating device and a gas discharge lamp with coils. Each coil has a terminal connected to an impedance network whose impedance function has a null point at a frequency close to a frequency that the electronic operating device produces before ignition of the gas dischar...
