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.

Abstract: The electrode comprises a pin-like shank (7) and a head part (8), the electrode, in the region of its discharge-side end, forming a vessel (9) for an emitter, in which there is a bore (16) which is filled with emitter material (10). The vessel, at its discharge-side end face, forms a collar, having an inner collar part (13) which is curved convexly toward the bore and an outer collar part (14) which is curved convexly toward the side wall of the vessel.

Abstract: An electric lamp with a base (6), which is structurally subdivided into an upper part (7) that retains the bulb and a substantially circular-cylindrical lower part (5) for external fastening, which lower part protrudes past the upper part, and the protruding portion (13) is embodied as a detent mechanism for the external fastening. The detent mechanism in each case includes an inward-facing detent protrusion (20) located on the outside, which is an integral component of the lower part, and a metal spring (24), located opposite the detent protrusion and cooperating with it, that is secured in the lower part.

Abstract: The invention relates to a transformer with at least one primary winding at least one secondary winding, with a winding unit, on which the primary winding is arranged in a first chamber and on which the secondary winding is arranged in a second chamber, in which a core, particularly a ferrite core, can be introduced, and which has an uptake element for a cap. The invention provides that the cap covers only a partial region of the primary winding and the secondary winding. The primary winding and secondary winding are adjacent to each other in this partial region. The cap is configured with a first separating wall arranged essentially perpendicular to the cap, and this wall is arranged between the first chamber and the second chamber in the assembled state.
