| 摘要 |
The invention relates to a high-pressure discharge lamp, which emits light at least in a defined wavelength range with a defined emission spectrum, having at least one burner ( 2 ), which comprises a discharge chamber ( 21 ), wherein at least the outer contour of the burner ( 2 ) has an elliptical shape in the area of the discharge chamber ( 21 ), two electrodes ( 41, 42 ) extending into the discharge chamber ( 21 ) which are arranged opposite one another and on the longest axis of symmetry of the discharge chamber ( 21 ), and a multilayer interference filter ( 3 ), which is arranged at least on th outer contour of the burner ( 2 ) in the area of the discharge chamber ( 21 ), wherein at least a portion of the light from the defined wavelength range may pass through the interference filter ( 3 ) and another portion of the light from the defined wavelength range may be reflected into the space between the two electrodes ( 41, 42 ).
