    • 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′).
    • 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)增加到超过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')。
