Definitions

  • the invention relates to a compact low-pressure discharge lamp consisting of a discharge vessel with electrodes and power supply, from a discharge vessel to which the discharge vessel is attached and composed of a housing, terminals and mounting plate with ballast socket, wherein the mounting plate mounted with the ballast in the interior of the base housing is and has connections for electrical connection of the mounting plate with the power supply lines and the connection contacts.
  • Such low-pressure discharge lamps may additionally be provided with a reflector or an enveloping bulb.
  • the discharge vessel consists of a multiply bent tube composed of one or more pieces, which is held in the housing with the aid of an elaborately designed carrier made of plastic or metal. An example of this can be found in the EP 0 044 196 ,
  • the elaborately designed support member for the discharge vessel leads to a correspondingly large dimensions for the low-pressure discharge lamp and on the other hand makes a manual assembly of the lamp required.
  • the manufacturing cost of such compact low-pressure discharge lamps are therefore relatively high.
  • the carrier for the discharge vessel is designed as a simple plate, which in turn is fastened in a further carrier. This further carrier is then attached to the housing of the base.
  • the further carrier can be designed as an envelope or as a reflector for the discharge vessel.
  • this further carrier can also be designed as a closure cap for the base housing
  • the plate is advantageously circular.
  • the ends may then be either by a hot melt ancestor, as in US Pat EP 1 105 906 listed, or be attached in a conventional manner by means of Skirting on the plate.
  • the plate advantageously has a retaining edge around the apertures for receiving the base cement.
  • the plate on the socket side facing brackets for contacts for electrical connection of the power supply lines with the electrical connections of the ballast on the mounting plate is provided.
  • An example of a corresponding contact can be found in the EP 0 854 497 where by means of spring elements which are held in receptacles on the end cap, a simple electrical connection between the power supply lines of the discharge vessel and the terminals of the ballast assembly is made on the mounting plate.
  • the further carrier on the inside of its lateral surface has an at least partially circumferential groove into which engage at least parts of the edge of the plate in the attachment of the plate in another carrier.
  • the further carrier on the inside of the lateral surface have a perpendicular to its axis of symmetry partially circumferential bead as a stop for the plate and the plate openings for the engagement of holding tools.
  • the further support on the outside of its lateral surface near the base facing the end of a perpendicular to its axis of symmetry, at least partially encircling bead, which engages in a correspondingly shaped groove on the inside of the base housing.
  • the base housing also has on the inside of its lateral surface a perpendicular to its axis of symmetry, at least partially circumferential stop on which rests the edge of the mounting plate in the direction of connection contacts.
  • the other carrier is designed so that it is assembled at Low-pressure discharge lamp with the edge of its base facing the end presses the mounting plate against this partially circumferential stop on the inside of its lateral surface. Characterized a tight fit of the mounting plate is ensured with the ballast in the lamp after assembly of the lamp from further support and socket.
  • the further carrier has at its end facing the base parallel to its axis of symmetry a plurality of circumferentially distributed short slots.
  • the support is advantageously made of plastic as well as designed as a reflector, outer bulb or end cap further carrier.
  • the other carrier as an envelope, reflector or end cap allows in production a simple change from compact low-pressure discharge lamps without enveloping pistons to the same lamp type with enveloping bulb or reflector.
  • the pure plug and snap connections a very simplified and fully automated assembly of the lamp is possible.
  • FIG. 1 is a sectional side view of a compact low-pressure discharge lamp 1 according to the invention with an envelope 2 reproduced.
  • the lamp has multi-wound discharge vessel 3 with an A malgam filling / which is filled in the pump tube 4.
  • the ends of the discharge vessel are inserted into openings in a support plate 5 made of plastic and fastened by Sockelkitt (not visible here) in the bead-shaped border 6 of the openings.
  • Sockelkitt not visible here
  • the electrodes melted into the ends of the discharge vessel 3 are connected to contacts which are fastened to the carrier plate 5 by means of holders 8.
  • the support plate 5 is snapped with its edge in a circumferential groove 9 on the inner wall of the enveloping piston 2.
  • the low-pressure discharge lamp 1 further has a substantially cylindrically shaped base 10 with a housing 11 and schematically illustrated connection contacts 12. Inside the housing 11, a mounting plate 13 is placed perpendicular to the lamp longitudinal axis on a peripheral stop 14.
  • the mounting plate 13 is formed as a board, wherein on the side facing the discharge vessel 3 side equipped with SMD components printed conductors and formed on the discharge vessel 3 side facing circuit elements of a ballast 15 are attached.
  • the outer bulb 2 with the discharge vessel support 5 is non-releasably connected to the housing 11 of the base 10 via an annular bead 16 on the outer surface of the Hüllkolbens near the free opening, which engages in a corresponding annular groove 17 in the inner periphery of the housing 11.
  • the mounting plate 13 is also pressed against the peripheral stop 14 and the plate-shaped support 5 of the discharge vessel 3 against corresponding webs 18 on the inner wall of the Hüllkobens 2.
  • spring tabs are pressed against the contacts against corresponding trace connections and so made an electrical connection between the ballast and electrodes.
  • FIG. 2 shows a low-pressure discharge lamp according to the invention, with a reflector 19.
  • the further support plate with the discharge vessel supporting the first support plate is not designed as an enveloping bulb, but as a reflector 19.
  • the other ingredients and the nature of the connection of these parts are in accordance with FIG. 1 illustrated low-pressure discharge lamp with enveloping pistons.
  • FIG. 3 is a low-pressure discharge lamp according to the invention with only one end cap 20 is shown.
  • the carrier plate with the Entiadungsgefäß In this case, as in the preceding figures, it is fastened in the further carrier plate, in which case this further carrier plate is embodied as an end cap 20. All other parts and connections are the same.
