Definitions

  • the invention relates to a lamp with a built-in lamp according to the preamble of patent claim 1, connecting means according to the preamble of patent claim 8 and a method for producing such a lamp according to the preamble of claim 20.
  • 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 have been developed with halogen incandescent lamps used, which are surrounded by an outer bulb and are therefore externally hardly distinguishable from conventional incandescent lamps.
  • Such a lamp is described on the Internet domain www.osram.de under the product name "HALOLUX® CLASSIC".
  • a one-sided squeezed halogen built-in lamp is held by a provided with a retaining wire clamp and the two power supply lines of the halogen lamp with power supply wires welded.
  • the retaining wire and the power supply wires are connected to the enveloping piston in the melting technique, ie the retaining wire and the power supply wires are fused with the outer bulb and glued the resulting unit with glue or putty in a screw base.
  • WO 03/043056 A2 discloses a lamp of similar construction, in which a halogen installation lamp squeezed on one side is inserted into a clamping element held by a retaining wire or a current supply wire and surrounded by an enveloping bulb. The connection of the holding or the Stromzu Glassdrahts with the enveloping piston takes place in the already described melting technique.
  • WO 98/40936 A1 discloses a halogen lamp with socket, wherein the halogen lamp is held detachably in a multi-part, non-conductive adapter with its own power supply sections arranged therein.
  • the invention has for its object to provide a lamp with a built-in lamp, in particular a Halogeneinbaulampe, suitable connection means, as well as a method for producing the lamp, in which opposite conventional solutions an improved mounting of the built-in lamp is made possible.
  • the lamp according to the invention has a built-in lamp, in particular a one-sided squeezed halogen lamp, which is inserted into a socket and surrounded by an enveloping bulb.
  • the recessed lamp is inserted into an electrically conductive mounting clip and electrically and mechanically connected via this with the base of the lamp.
  • This mounting clip adopts both the electrical contact and the mechanical fixation of the built-in lamp, so that it is possible to dispense with separate power supply lines, as required in the solution shown in WO 98/40936 A1, and the device complexity is significantly reduced.
  • the mounting clip is surrounded by base and outer bulb and thus does not interfere with the lamp design.
  • the mounting of the recessed lamp without melting technology can be performed so that a more stable mounting of the built-in lamp allows and the cold shock resistance compared to conventional solutions is significantly improved.
  • the manufacture of the lamps is also significantly simplified in comparison to the generic method, since the separate steps for forming the melt can be omitted.
  • the recessed lamp used has two power supply lines, wherein a first power supply directly to the mounting clip and a second power supply via a power supply wire with a ground contact of the base of the lamp electrically is connected, wherein the first power supply is preferably welded or soldered to an outer wall of the mounting clip.
  • the mounting clip can be screwed into the base via peripheral screw-in projections.
  • the mounting clip is thus screwed directly into the base after insertion of the built-in lamp and the enveloping piston then placed.
  • the mounting clip can be pressed with the base.
  • This variant is used especially for larger sockets (for example, E27 socket), wherein a transition clip is then placed on the mounting clip, which is then pressed with the base.
  • the mounting clip used for larger screw base has in an advantageous solution, a peripheral wall which surrounds a portion of the enveloping piston and is encompassed by a base sleeve.
  • the bonding compound is preferably introduced into an annular space bounded by enveloping pistons and base, wherein the adhesive or putty can be distributed over the openings of the circumferential wall in the annular space.
  • the adhesive or putty can be distributed over the openings of the circumferential wall in the annular space.
  • the peripheral wall of the transition clip may preferably have an edge facing the envelope piston with an enlarged diameter, so that it can be brought into contact with the base sleeve.
  • To limit the depth of immersion when inserting the mounting clips in the base limiting elements are preferably arranged on the outer periphery.
  • the mounting clip has an approximately cylindrical jacket-shaped receiving portion, which is preferably formed by two diametrically arranged recesses in which a plane-parallel flattened portion of a pinch of the integral lamp is receivable, with an adjoining the flattened portion of the pinch extended edge portion outside of the receiving portion comes to rest ,
  • the recesses are formed with diametrically opposed projections, which are brought into abutment with the flattened portion of the pinch and provided with chamfers, accumulate on the arranged at the onset of the integral lamp at the pinch projections.
  • the insertion bevels facilitate the insertion of the pinch in the installation of the integral lamp and limiting the run-up projections whose immersion depth in the mounting clip.
  • a first power supply is connected to a power supply wire and a second power supply bent prior to insertion of the built-in lamp in the connection clip.
  • This power supply is fixed after insertion of the built-in lamp in the mounting clip on the outer wall, preferably welded, and thus positioned and held the built-in lamp.
  • the power supply wire is cut to length and ground contact soldering is performed.
