Abstract

The lamp comprises a discharge vessel (2) which is closed off in a vacuum-tight manner and is arranged in an outer bulb (12), a getter material being held on a support body inside the outer bulb (12). The support body is a support strip (31) to which the getter material is applied, the support strip being bent in such a way that it is automatically held in the outer bulb (12) without the need for any auxiliary means.
