  • Halogen incandescent lamps are becoming increasingly popular in many areas of daily life due to their good quality of light and long service life. Even in applications with high demands on aesthetics and cost-effectiveness, the desire arose to replace conventional incandescent lamps operating with line voltage with halogen incandescent lamps. For these reasons, lamps were developed with halogen incandescent lamps used, which are surrounded by an outer bulb and are therefore externally hardly distinguishable from conventional bulbs for general lighting.
  • Such a lamp is described on the Internet domain www.osram.de under the product name "HALOLUX ® CLASSIC”.
  • a one-sided squeezed halogen incandescent lamp is held by a holding wire provided with a clamp and the two power supply lines (Strotze) of the halogen lamp with power supply wires welded.
  • the retaining wire and the power supply wires are connected to a lamp base (Tellerfuß) of the enveloping piston in a melting technique, wherein the lamp base merged with the enveloping bulb and the resulting unit is inserted into a socket, such as a screw or bayonet base.
  • WO 03/043056 A2 discloses a lamp of similar construction, in which a one-sided pinched halogen built-in lamp in one of a retaining wire or a Power supply wire held clamp element used and surrounded by an outer envelope.
