  • Such halogen incandescent lamps are intended in particular for operation on high voltage (HV) with typically 100 to 250 volts.
  • the WO-A 2009156251 discloses a mounting for an integral lamp in an outer bulb, wherein the holder has a metallic mounting clip, which sits on the end of the Tellerfußes.
  • the outgoing from the built-in lamp outer power supply lines are firmly connected to the towering from the base plate feeder lines for locking. In this case, a complex machine technology is required.
  • the object of the present invention is, in a lamp according to the preamble of claim 1, the installation of a built-in lamp in an outer bulb by means of mounting clip safely and reliably, but nevertheless to accomplish in a simple manner.
  • the invention ensures the simple and reliable production of a lamp with built-in lamp.
  • the invention provides, in particular, a single-ended electric lamp with an outer bulb fastened to a base and an integral lamp which is arranged inside the outer bulb and which is robust and easy to produce.
  • the lamp or integral lamp is a high-voltage halogen incandescent lamp, wherein at least two pins act as power supply wires.
  • the lamp can also be a high-pressure discharge lamp.
  • the built-in lamp has a piston with pinch, which is supported by means of a retaining clip on the base.
  • the retaining clip has a plate-like body and three spring feet attached thereto, which allow a centering holder and a contact in the base sleeve.
  • the lamp or integral lamp consists essentially of a hermetically sealed lamp vessel or bulb with pinch, of at least one light source and a power supply system for the lamp, which usually has two external power supply lines, which protrude axially parallel from the pinch.
  • the bulb is usually a filament, but it can also be a discharge arc between two electrodes.
  • the light source will always be described as a luminous element for the sake of simplicity. It is often connected to the external power supply lines via internal power supply lines and possibly foils.
  • the power supply system connects the lamp arranged in the interior of the lamp vessel with a lamp arranged outside the base, which is to be connected to a power source.
  • the power supply system consists, for example, of inner power supply wires, of fuser films and of outer power supply wires, wherein the aligned ends of the inner and outer power supply wires and the power supply wires interconnecting fusing films are fused in the lamp crimp.

  • a three-point holder On the apron in the direction of the base a three-point holder is mounted to rest on the skirt inner edge. These are three spring feet, which bear against the socket inner edge after joining.
  • the shape and length of the spring feet are sized to compensate for the tolerance of the inside diameter of the skirt edge. As a result, the clip sits stably in the base sleeve and ensures a secure power contact to the base sleeve.
  • the pinch of the integral lamp is preferably held by means of two mutually opposite spring tongues in the region of a lateral edge of the pinch.
  • corresponding spring tongues can also support the other lateral edge of the pinch.
  • this can advantageously be dispensed with in order to avoid luminous flux losses due to shading due to the additional spring tongues.
  • a first of the two outer power leads is welded to the base plate. This has to facilitate for about the middle of a bead on which the weld can take place. This first external power supply ends at the base plate.
  • the second external power supply is without any contact with the clip, it can be connected to an extension wire or be made long, so that they can make in each case a direct connection to the socket center contact.
  • the base plate is curved in a wavelike manner from a first lateral edge to a second lateral edge, so that it has two to three partial plates.
  • a first sub-plate is preferably aligned parallel to the broad side of the pinch, said first sub-plate is approximately in the extension of the plane of a first broad side of the pinch towards the base. Approximately in the middle follows a slope as a second sub-plate, which is also oriented axially parallel. It extends, seen transversely to the longitudinal axis, to about halfway between the two broad sides of the pinch.
