LAMP SYSTEM HAVING A GAS-DISCHARGE LAMP AND OPERATING METHOD ADAPTED THEREFOR

In order to control a lamp system having a gas-discharge lamp, an electronic ballast and a control unit, a performance-influencing controlled variable of the lamp system is used. In order to specify,on the basis of this, a method for operating a gas-discharge lamp which enables operation with a high emission performance irrespective of the design of the lamp and any changes on account of lamp ageing and without knowledge of the optimum operating temperature, the invention proposes that light intensity control is provided, in which an actual value of a light intensity emitted by the gas-discharge lamp is measured by means of a light sensor and the emitted light intensity is used as the controlled variable. 为了调节具有气体放电灯、电子镇流器和控制单元的照明系统，使用照明系统的影响功率的调整变量。为了由此出发给出一种用于运行气体放电灯的方法，该方法能够与气体放电灯的结构以及由于灯老化而可能出现的改变无关地、在不必识别出最优的运行温度的情况下以高发射功率实现运行，根据本发明提出：进行光强度调节，在该光强度调节中借助光传感器测量由气体放电灯发射的光强度的实际值并且将所述发射的光强度用作调整变量。
