    • A cooling unit (2) having a pump (20) for generating an airflow is provided for cooling a High Power lamp (10) during operation. The value of the airflow is controlled by a control unit (3) which comprises a driver (30) for determining a required value of the airflow on the basis of the operating power of the lamp (10). The control unit (3) comprises two pressure sensors (32, 33) for measuring a pressure of the airflow as well as a pressure drop of the airflow across an orifice (31). The driver (30) is designed for processing the measuring results in order to determine an actual value of the airflow. The value of the airflow is accurately controlled by adjustment of the power supply to the pump (20) in order to obtain a match of the actual value of the airflow and the required value of the airflow.
    • 提供具有用于产生气流的泵(20)的冷却单元(2),用于在操作期间冷却大功率灯(10)。 气流的值由控制单元(3)控制,控制单元(3)包括用于基于灯(10)的操作功率来确定气流的所需值的驱动器(30)。 控制单元(3)包括两个压力传感器(32,33),用于测量气流的压力以及穿过孔口(31)的气流的压降。 驱动器(30)被设计用于处理测量结果以便确定气流的实际值。 通过调节对泵(20)的供电来准确地控制气流的值,以便获得气流的实际值和气流的所需值的匹配。

    • A method and a circuit arrangement for operating a discharge lamp, in particular during the first hours of operation after lamp manufacture, are described. The method and the circuit arrangement are provided in particular for high-pressure gas discharge lamps (HID or high intensity discharge lamps or UHP or ultra high performance lamps). Furthermore, a lighting unit with a discharge lamp and such a circuit arrangement and a projection system with a projection display and such a lighting unit are described. Switching-over between various modes of operation with different operating frequencies serves to avoid that the burning voltage of the lamp drops into a region of a minimum voltage of a lamp driver unit below which the latter can no longer drive the lamp with its rated power or a desired power.
    • 描述了用于操作放电灯的方法和电路装置,特别是在灯制造之后的第一小时操作期间。 该方法和电路装置特别用于高压气体放电灯(HID或高强度放电灯或UHP或超高性能灯)。 此外,描述了具有放电灯和这种电路装置的照明单元以及具有投影显示器和这种照明单元的投影系统。 在不同操作频率的各种操作模式之间的切换用于避免灯的燃烧电压下降到灯驱动器单元的最小电压的区域中,在该区域中,后者不能以其额定功率驱动灯,或者 所需的力量
