Abstract
The invention describes a method of cooling a lamp () in a projector (') independently of an orientation (P, P) of the projector (′), which method comprises directing a cooling airflow () symmetrically at a burner () of the lamp () during operation of the lamp (); and controlling the cooling airflow () 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 (T) in a base region of the burner () drops below a predefined minimum operating temperature (T) to allow a blackening of an inside wall () of the burner (), and during cooling at the second cooling level (C-II), the temperature (T) in an upper region of the burner () increases above a predefined maximum operating temperature (T) and the temperature (T) in the base region of the burner () increases above the predefined minimum operating temperature (T) to facilitate a cleaning of the burner wall (). The invention further describes a cooling module controller () for use in an orientation-independent cooling arrangement () of a projector (′); an orientation-independent cooling arrangement () for cooling a lamp () in a projector (′) independently of an orientation (P, P) of the projector (′); and a projector (′).
