Abstract
To reduce the size of the base and a socket therefor of a single-ended, sle-based, high-pressure discharge lamp, for example a mercury discharge lamp with halogen and noble gas additives therein, possibly including rare earths, a base (5) has a generally conically shaped portion (8) in the region adjacent the discharge vessel, the discharge vessel being formed with two supply shafts (3, 4) one of which is seated in a recess in the smaller part of the conical portion. The base is formed with a centering stub (9), preferably of rectangular cross section, and extending away from the discharge vessel, the centering stub having a lateral slot (11) within which one of the terminals (12) of the lamp is located. The other terminal is formed by a metal strip (14) carried through the cone surface and terminating laterally of the centering stub (9) at the side remote from the first terminal (12). The socket is formed with two chambers, separated by a rib or wall (19), one chamber receiving the centering stub (9) and having a connector (16) located therein, in form of a leaf spring, engaging within the slot (11) and against the one terminal (12) of the lamp; the second chamber, subdivided by the wall (19), retains the second terminal (17) to engage the end of the contact strip (14) and forming the second terminal (13) of the lamp. The socket as well as the base are made of temperature-resistant ceramic.
