    • The invention describes a method of driving a gas-discharge lamp (1), wherein the lamp (1) is driven at any one time using one of a number of driving schemes and wherein the operating voltage of the lamp (1) is monitored to obtain a number of operation data values (D) during operation of the lamp (1), a target voltage (VT) is determined on the basis of at least one of the number of operation data values (D), and a driving scheme switch-over occurs according to a relationship between the target voltage (VT) and the operating voltage of the lamp (1). The invention further describes a driving unit (10) for driving a gas-discharge lamp (1) comprising a voltage monitoring unit (12) for monitoring the operating voltage of the lamp (1) to obtain a number of operation data values during operation of the lamp (1); a target voltage determination unit (13) for determining a target voltage (VT) on the basis of at least one of the number of operation data values, and a driving scheme switching unit (14) for switching from a first driving scheme to a second driving scheme according to a relationship between the target voltage (VT) and the operating voltage of the lamp (1).
    • 本发明描述了一种驱动气体放电灯(1)的方法,其中使用多个驱动方案中的一种驱动任何时间来驱动所述灯(1),并且其中监视所述灯(1)的工作电压 在灯(1)的操作期间获得多个操作数据值(D),基于操作数据值(D)的数量中的至少一个和驱动方案开关来确定目标电压(VT) 根据目标电压(VT)和灯(1)的工作电压之间的关系发生。 本发明还描述了一种用于驱动气体放电灯(1)的驱动单元(10),其包括用于监视灯(1)的工作电压的电压监视单元(12),以在操作期间获得多个操作数据值 灯(1); 目标电压确定单元(13),用于基于所述操作数据值的数量中的至少一个确定目标电压(VT);以及驱动方案切换单元(14),用于从第一驱动方案切换到第二驱动方案 根据目标电压(VT)和灯(1)的工作电压之间的关系,驱动方案。
