Abstract: A method for fitting a base for a discharge lamp is provided. The method may include providing a discharge lamp with an end region, on which an option is provided for making contact with an electrode located in the interior of the discharge vessel; applying material to the end region; positioning a base sleeve onto the end region with the material; and positioning a clamping ring onto the base sleeve; wherein the clamping ring is of the kind that has at least one bead.

Abstract: A discharge lamp may include a substantially ellipsoidal discharge vessel that surrounds an anode and a cathode that are respectively fixed by current-carrying electrode holders, the latter being guided through bulb shafts arranged diametrically on the discharge vessel, there being provided around the electrode holders at the transition from the discharge vessel to the bulb shafts constrictions that form a connecting channel between the discharge space, surrounded by the discharge vessel, and in each case the bulb shaft spaces surrounded by the bulb shafts, wherein at least one of the discharge vessel, the constrictions and the anode coating is designed in such a way as to reduce or avoid blackening of the discharge vessel in the light-emitting region.

Abstract: A direct current discharge lamp with an anode (10) and a cathode (12) that are arranged opposite one another at a predetermined distance (r) inside a discharge vessel (14) filled with a filling gas, it being possible to apply electric power (P) to the anode (10) and the cathode (12) in order to produce a gas discharge. At least the predetermined distance (r) between the anode (10) and the cathode (12), the electric power (P) and a geometry of the anode (10) are adapted to one another in such a way that a region (22) of a surface (24) of the anode (10) facing the cathode (12) is free flowing in the heated state of the direct current discharge lamp.
