A motor vehicle headlight element is specified which has at least one light-emitting diode and at least one control apparatus. The control apparatus is suitable for processing a signal which is dependent on a measurement variable and for applying a current corresponding to the signal, to the light-emitting diode. The control apparatus and the light-emitting diode are arranged on a common mount.

Disclosed is a lamp, particularly a halogen incandescent lamp, comprising a bulb that is provided with a pinch seal which is inserted into a base by means of an attachment ring. The attachment ring has a receiving section within which the pinch seal is clampingly fastened by means of attachment ring brackets that are supported on support surfaces. According to the invention, the support surfaces are placed at an angle from the longitudinal axis of the lamp.

The invention relates to a lamp base with a plastic base part which has electrical connections for the power supply of at least one lighting device of the lamp, the lighting device being enclosed by a lamp vessel and the electrical connections being configured by metal pins. The first ends of these pins project laterally, perpendicular to the longitudinal extension of the lamp base, from the plastic base part in order to establish electrical contact with the lamp socket, and the second ends are adapted to connect a power supply wire for the at least one lighting device which wire is to the outside of the lamp vessel. The invention is characterized in that the plastic base part has a recess on a lower face of the plastic base part facing away from the lamp vessel, the two ends of the metal pins being disposed in the recess.

The invention relates to a lamp base and to a high-pressure discharge lamp having a starting transformer arranged in the lamp base. According to the invention, an electrical contact element, which connects the starting voltage output of the starting transformer to the inner power supply line which protrudes from the discharge vessel, is in the form of a module having a plastic injection-molded part of the lamp base.

The lamp according to the invention has a metal holder part 2 with a rece in which the pinch seal 10 of the lamp bulb 1 is clampingly fixed with the aid of a plurality of support tabs 21a, 21b, 22a, 22b, 23a, 23b. In order to reduce the danger of damage to the pinch seal 10 when the lamp is being mounted on its base, the pinch seal 10 is tapered is graduated fashion toward the base, and all the support tabs 21a, 21b, 22a, 22b, 23a, 23b that act upon the pinch seal 10 are oriented toward the broad sides of the pinch seal 10, which is substantially rectangular in cross section, while the narrow sides of the pinch seal 10 are located in the holder part 2 without touching it. The narrow sides of the pinch seal (10) are retained in the holder (2) spaced from the holder. Guide ribs (50a, 50b) are formed on the pinch seal (10) positioned off-center, and laterally relatively staggered. Support tabs (21, 20b) fitting against the pinch seal in the region of the guide ribs, are formed with recesses (24a, 24b), which are wider than the width of the guide ribs, and also laterally staggered and offset so that the rib-and-recess combination provide for reliable lateral positioning of the lamp in the base, by laterally positioning the pinch seal in the base, and, further, ensuring that the seal cannot cant upon insertion of the lamp in the base. The ribs and recesses can be so arranged to form, respectively, right and left lateral abutment and support surfaces.

To reliably and simply connect one end of a double-ended discharge vessel it (1) and a surrounding envelope (11) to a base (8), the base has a base sleeve (8a) which encloses a base holder portion (8b). The envelope (11) is melt-connected to the discharge vessel unit (1), for example just beyond pinch seals formed thereon, and is additionally formed with an extension (11a) which is, in turn, melt-connected to the holder portion (8b) of the base. Preferably, a metallic cuff is placed within the holder portion so that, by high-frequency inductive heating, a reception region (8d) of the holder portion can melt and tightly grip the extension (11a) of the envelope. To improve adhesion, the surface of the extension region (11a) may be ribbed, knurled or otherwise, slightly deformed.

The invention relates to a dipping cap comprising a filament for a dual-filament lamp. The dimension between an outlet of an outgoing section of the filament, on the side of the base, and the point on the outgoing section of the filament, arranged opposite the outgoing section of the filament on the side of the base and welded to the dipping cap, measures more than approximately 5.2 mm and less than 9.7 mm, and the dimension between the outlet of the outgoing section of the filament, on the side of the base, and the front surface of the dipping cap, which is adjacent to the outgoing section of the filament, welded to the dipping cap, measures more than approximately 5.9 mm and less than 11.9 mm.
