Abstract:
Method for controlling the operational performance of at least one gas discharge lamp wherein a manipulated-variable value for at least one specific controlled variable is generated with the aid of a controller as a function of a differential value between a predetermined desired value and an actual value of a specific operating parameter of the at least one gas discharge lamp, for the purpose of controlling the brightness of the at least one gas discharge lamp, and wherein the controller has a proportional component or amplification factor, said method comprising the steps of:feeding the desired value directly to the controller; andsetting the value of the proportional component or the amplification factor of the controller as a function of the desired value in such a way that the proportional component or amplification factor of the controller is reduced for desired values which correspond to comparatively high brightness values and is increased for desired values which correspond to comparatively low brightness values.
