Definitions

  • the invention relates to a compact low-pressure discharge lamp from a discharge vessel with electrodes and power supplies, from a discharge vessel support to which the discharge vessel is attached and with a housing, connecting contacts and mounting plate Ballast assembly composite base, the mounting plate is attached with the ballast assembly inside the base housing and connections for the electrical connection of the mounting plate with the Has power leads and the connecting contacts.
  • Such low-pressure discharge lamps can additionally with a Be provided reflector or an envelope bulb.
  • the discharge vessel consists of one or more pieces composite multi-bent pipe, which is elaborate with the help of a designed carrier made of plastic or metal held in the housing becomes. An example of this can be found in EP 0 044 196.
  • the elaborately designed carrier part for the discharge vessel leads to one correspondingly large dimensions for the low-pressure discharge lamp and on the other hand requires manual assembly of the lamp.
  • the manufacturing costs for such compact low-pressure discharge lamps are therefore relatively high.
  • the Carrier for the discharge vessel designed as a simple plate, which in turn in another carrier is attached. This additional carrier is then on the housing attached to the base.
  • the further carrier can be used as an envelope bulb or as a reflector for the discharge vessel be designed.
  • this additional support can also be used as a End cap for the base housing
  • the plate is advantageous circular.
  • the discharge vessel is very easy to attach when the Plate two openings for receiving the ends of the discharge vessel having.
  • the ends can then either be heated by a hot melt, as listed in EP 1 105 906, or in a conventional manner by means of Base putty to be attached to the plate.
  • the plate points advantageous around the openings a holding edge for receiving the Base cement on.
  • the plate advantageously has brackets on the side facing the base for contacts for the electrical connection of the power supplies with the electrical connections of the ballast assembly on the mounting plate on.
  • An example of a corresponding contact can be found in EP 0 854 497, where by means of spring elements which are in receptacles on the end cap be kept a simple electrical connection between the power supply lines of the discharge vessel and the connections the ballast is made on the mounting plate.
  • the other one Carrier on the inside of its lateral surface an at least partially circumferential Groove in the at least parts of the edge of the plate when fastening engage the plate in the other carrier.
  • the further carrier can be on the inside of the lateral surface Bead partially circumferential to its axis of symmetry as a stop for the plate and the plate openings for the engagement of holding tools exhibit.
  • the other one Carrier on the outside of its outer surface near the base facing End one perpendicular to its axis of symmetry, at least partially circumferential bead, which in a correspondingly designed groove on the Engages inside the base housing.
  • the base housing also has on the inside of its outer surface one perpendicular to its axis of symmetry, at least partially revolving Stop on which the edge of the mounting plate towards the connection contacts rests.
  • the other carrier is designed so that when assembled Low pressure discharge lamp with the edge of its that End facing the mounting plate against this partially circumferential Stops on the inside of its outer surface. This will after assembling the lamp from a further support and base a firm one Ensure the mounting plate with the ballast in the lamp.
  • the carrier is advantageously made of plastic just like that as a reflector,
  • the envelope flask or end cap designed additional supports.
  • the optional design of the additional support as an envelope bulb, reflector or end cap enables easy change in production of compact low-pressure discharge lamps without an envelope bulb same lamp type with envelope bulb or reflector. Through the pure Steckund Snap connections is a very simplified and fully automated Assembly of the lamp possible.
  • FIG. 1 is a sectional side view of a compact according to the invention
  • the lamp has multiple-wound discharge vessel 3 with an amalgam filling / which is filled into the pump tube 4.
  • the ends of the discharge vessel are inserted into openings in a carrier plate 5 made of plastic and by means of base cement (not visible here) in the bead-shaped border 6 of the breakthroughs attached.
  • About current leads 7 are in the ends of the discharge vessel 3 melted electrodes with contacts connected, which is fastened to the carrier plate 5 by means of brackets 8 are.
  • the edge of the carrier plate 5 is in a circumferential groove 9 on the inner wall of the envelope piston 2 snapped.
  • the low-pressure discharge lamp 1 also essentially has one cylindrical base 10 with a housing 11 and schematically shown connection contacts 12. Inside the housing 11 is a mounting plate 13 perpendicular to the lamp longitudinal axis on a circumferential Stop 14 hung up.
  • the mounting plate 13 is designed as a circuit board, being on the side facing the discharge vessel 3 with SMD components assembled conductor tracks and formed on the discharge vessel 3 facing away circuit elements of a ballast 15 attached are.
  • the envelope bulb 2 with the discharge vessel support 5 is unsolvable for lay people with the housing 11 of the base 10 via an annular bead 16 on the outer circumferential surface of the envelope piston connected near the free opening, which engages in a corresponding annular groove 17 in the inner circumference of the housing 11.
  • the envelope piston 2 is attached to the housing 11 of the base 10 is also the mounting plate 13 against the circumferential stop 14th and the plate-shaped carrier 5 of the discharge vessel 3 against corresponding Web 18 pressed on the inner wall of the envelope 2.
  • Spring tabs not shown here on the contacts against corresponding Conductor connections pressed and so an electrical connection made between ballast and electrodes.
  • Figure 2 shows a low-pressure discharge lamp according to the invention, with a Reflector 19.
  • the further support plate with which the discharge vessel supporting first support plate not as an envelope piston, but as Reflector 19 executed.
  • the other ingredients and the type of connection these parts correspond to the low-pressure discharge lamp shown in FIG with envelope flask.
