Embodiment Construction

[0027] 1 to 4 schematically show a plastic injection molded part 15 of a lampholder and contact lugs 16 , 17 , which form part of the leads of the filament coil, according to a first exemplary embodiment of the invention. The plastic injection molded part 15 is a component part of the socket of the halogen incandescent lamp shown schematically in FIG. 10 , which is used as a light source in a motor vehicle headlight.

[0028] The lamp has a substantially cylindrical bulb 10 made of glass with a hermetically closed constricted base 10a. The top 10b of the bulb 10 is provided with a light-absorbing coating. A helical filament 11 parallel to the bulb axis serves as the light source and is electrically conductively connected to two lead wires 12 , 13 consisting of molybdenum wires emerging from the constriction base 10 a. The constricted base 10a of the bulb 10 is fixed on a metal support, which is composed of a bowl-shaped holder 14a, an intermediate ring 14e and a ring-shaped s...

Abstract

The invention relates to a lamp base comprising at least one lead-in wire (16) and means for sealing the lamp base in the area of the at least one lead-in wire (16). Said sealing means are provided with at least one of the following combination of characteristics A, B, and C: A. an elastomer (161) or rubber that positively and annularly surrounds a section of the at least one lead-in wire (16), said section of the at least one lead-in wire (16), which is surrounded by the elastomer (161) or rubber, being positively embedded in an injection-molded plastic part (15) of the lamp base; B. a surface area of the at least one lead-in wire, which has a profile or a rough surface and is positively embedded in an injection-molded plastic part of the lamp base; C. a section of the at least one lead-in wire, which is fitted with slots and is positively embedded in an injection-molded plastic part of the lamp base.

Description

technical field [0001] The invention relates to a lampholder and an electric lamp with such a lampholder. Background technique [0002] An electric lamp having such a base is known from publication WO 97 / 40521. This document describes a halogen incandescent lamp for motor vehicle headlights with a base having two leads for a coiled filament. Two silicon tubes are provided in the base, which serve to seal the base in the region of the two lead wires. These silicone tubes each surround a part of the lead in an annular manner and are arranged by means of a press fit between the respective lead and the wall of the socket clamp. This type of sealing is relatively expensive, since a socket clamp must be provided for the silicon tube in the lamp socket, as well as a device for producing a press fit. Contents of the invention [0003] The object of the present invention is to provide a lampholder with simplified sealing of the lead wires. [0004] According to the invention, t...
