Abstract (en)
[origin: EP0316617A2] In a high-pressure discharge lamp (1), the tubular discharge vessel (8) is held in the outer bulb (2) by means of a frame (5); the frame (5) consists of two supply wires (6a, 6b), one of which is connected to a supporting bar (12), aligned parallel to the discharge vessel (8); at least one of the power supplies led out of the discharge vessel (8) is connected to the frame (5) in an electrically conductive and mechanically rigid manner via a leaf spring stamped part (15); the latter has an outer frame part (17) and an inner intermediate part (18) sprung against it; this simplified construction of the frame (5) simultaneously solves the problem of thermal expansion and that of the electrical supply. <IMAGE>
