摘要： The invention describes a method of shutting down a high pressure discharge lamp (1) in which a pair of electrodes (2) are disposed in an arc tube (3). This method comprises the steps of reducing the lamp power (PA) to a reduced operation level that enables the maintenance of an arc discharge between the electrodes (2) in a transition state from a lighting state to an extinguished state; driving the lamp (1) at the reduced operation level such that that the lamp (1) cools down; monitoring the lamp voltage (U) during this lamp power reduction process and during driving of the lamp (1) at the reduced operation level with regard to a defined discharge process stability criteria and increasing the lamp power (PA) if the discharge process stability criterion is not satisfied; completely shutting down the lamp power (PA) after sufficient duration to allow the lamp (1) to cool down to a state in which the gas pressure is such that the lamp (1) could be reignited shortly after being extinguished. Moreover the invention describes an appropriate driving unit (7) for driving a high pressure discharge lamp (1) and an image rendering system (40), particularly a projector system, comprising such a driving unit (4).

摘要： The invention describes a method of cooling a lamp (1) in a projector (2, 2′) independently of an orientation (Pdesk, Pceiling) of the projector (2, 2′), which method comprises directing a cooling airflow (4) symmetrically at a burner (10) of the lamp (1) during operation of the lamp (1); and controlling the cooling airflow (4) alternately between at least a first cooling level (C-I) and a second cooling level (C-II) such that, during cooling at the first cooling level (C-I), the temperature (Tbase) in a base region of the burner (10) drops below a predefined minimum operating temperature (Tmin) to allow a blackening of an inside wall (100) of the burner (10), and during cooling at the second cooling level (C-II), the temperature (Ttop) in an upper region of the burner (10) increases above a predefined maximum operating temperature (Tmax) and the temperature (Tbase) in the base region of the burner (10) increases above the predefined minimum operating temperature (Tmin) to facilitate a cleaning of the burner wall (100). The invention further describes a cooling module controller (31) for use in an orientation-independent cooling arrangement (30) of a projector (2, 2′); an orientation-independent cooling arrangement (30) for cooling a lamp (1) in a projector (2, 2′) independently of an orientation (Pdesk, Pceiling) of the projector (2, 2′); and a projector (2, 2′).
摘要翻译：本发明描述了一种与投影仪（2,2'）的方位（Pdesk，Pceiling）独立的方式来冷却投影仪（2,2'）中的灯（1）的方法，该方法包括引导冷却气流（4）在灯（1）的操作期间对称地在灯（1）的燃烧器（10）处; 并且在至少第一冷却水平（CI）和第二冷却水平（C-II）之间交替地控制冷却空气流（4），使得在第一冷却水平（CI）的冷却期间，在燃烧器（10）的基部区域下降到预定的最小工作温度（Tmin）以下，以允许燃烧器（10）的内壁（100）变黑，并且在第二冷却水平（C-II）的冷却期间，燃烧器（10）的上部区域中的温度（Ttop）增加到高于预定的最大工作温度（Tmax）并且燃烧器（10）的基部区域中的温度（T base）增加到高于预定的最小工作温度（Tmin ）以便于清洁燃烧器壁（100）。本发明还描述了一种用于投影仪（2,2'）的朝向不依赖的冷却装置（30）的冷却模块控制器（31）。独立于投影仪（2,2'）的方位（Pdesk，Pceiling）的用于冷却投影仪（2,2'）中的灯（1）的取向独立冷却装置（30）; 和投影仪（2,2'）。
