Abstract (en)
[origin: WO2010086191A2] The invention relates to a method for operating a gas discharge lamp, wherein the gas discharge lamp is operated by a square-wave current, wherein the lamp current has predetermined commutation points over time and a commutation for creating a commutation pattern can take place at said commutation points. The invention likewise relates to an electronic operating device having an igniter, an inverter and a control circuit, wherein the electronic operating device carries out said method. The invention likewise relates to a projector having an electronic operating device, wherein the projector is designed to project an image during performance of the method without the performance of the method being viewable in the image.
