ABSTRACT:
The high-pressure discharge lamp has a discharge vessel (1) with seals (2) on each of which a metal clamping plate (20) is present. The discharge vessel is accommodated in an outer bulb (10) which has cylindrical portions (12). The clamping plates (20) have transversely flanged rims (24, 25) from which elastic tongues (23) extend towards the outer bulb in tangential direction and press against a cylindrical portion (12) of the outer bulb with clamping force. The clamping plates (20) render it possible to suspend the discharge vessel (1) in the outer bulb (10), keeping the discharge vessel centered and forming a buffer in the case of shocks.
