  • It is an object of the invention to provide a compact, low-pressure discharge lamp of the type mentioned provide a compact structure owns and is simple and therefore inexpensive to manufacture.
  • the object is achieved in the compact low-pressure discharge lamp according to the invention by a carrier for the discharge vessel with essentially H-shaped cross section solved, the carrier from a plate with there is a collar running along the edge on each side of the plate.
  • Discharge vessel carrier is now on the one hand a cover part and on the other hand that Housing of the base attached.
  • the cover part can be used as an envelope bulb or as a reflector for the discharge vessel be designed.
  • This cover can also be used as an end cap for an envelope bulb or reflector be designed for the base housing.
  • the plate is H-shaped Discharge vessel carrier advantageously designed circular.
  • the discharge vessel is easy to attach when the plate of the discharge vessel carrier two openings or half-shell-shaped depressions for receiving the ends of the discharge vessel.
  • the Ends can then either by a hot melt ancestor as in listed in EP 1 105 906, or in a conventional manner by means of base cement or glue are attached to the plate.
  • the plate points advantageous around the openings or half-shell-shaped depressions around a holding edge for receiving the base cement or adhesive, whereby the holding edge advantageous in the case of breakthroughs on the base facing side of the plate and in the case of half-shell-shaped depressions is attached to the side of the plate facing the cover.
  • the discharge vessel can be fastened to the discharge vessel carrier also by means of a trough into which a part of the discharge vessel, e.g. a Bend is inserted.
  • This type of attachment can also be added be useful for fixing the two ends of the discharge vessel, especially if the discharge vessel is long and bent several times is.
  • the plate also preferably has on the side facing the base Mounts for contacts for the electrical connection of the power supply with the electrical connections of the ballast arrangement on the mounting plate.
  • 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 an inexpensive electrical connection between the power supply lines of the discharge vessel and the connections the ballast is made on the mounting plate.
  • the base housing has for attaching the base to the H-shaped support an at least partially circumferential on the inside of its lateral surface Groove into the hook-shaped formations of the other, engage the collar of the plate facing the base housing.
  • Each collar advantageously has between 2 and 8 hook-shaped configurations on.
  • the hook-shaped formations have depending of the base housing diameter are between 1 and 30 mm wide - with respect to the two collars - laterally offset from each other, so that the projections of the hook-shaped formations become one Do not overlap the plane perpendicular to the lamp axis.
  • the hook-shaped formations on the two collars are still divided into several segments by narrow slits reaching to the plate. This segmentation leads to a reduction in the joining force. number and width of the segments are coordinated so that under Utilization of the anti-rotation lock listed above in the relevant The required strength values are adhered to and the joining forces lie in an area that is easy to control even with manual assembly is.
  • the H-shaped carrier is made of plastic, the material being advantageous is transparent.
  • the cover part is preferably made of plastic, with one design of the cover part as an enveloping bulb made of a glass bulb with an attached Plastic edge can exist.
  • cover part as an envelope bulb, reflector or End cap enables easy change in production compact low-pressure discharge lamps without envelope bulbs on the same Lamp type with envelope bulb or reflector. Through the pure plug and Snap connections is a very simplified and fully automated assembly the lamp possible.
  • FIG 1 is a sectional side view of a compact according to the invention
  • Low-pressure discharge lamp 1 with a envelope 2 designed as an envelope bulb Cover part made of plastic.
  • the lamp has a multiple winding discharge vessel 3 with an amalgam filling.
  • the ends of the discharge vessel are in openings in the circular plate 4th of an H-shaped discharge vessel support 5 made of plastic and by means of Base putty (not visible here) in the bead-shaped holding edge 6 around the Breakthroughs attached.
  • About current leads 7 are in the ends of the Discharge vessel 3 melted electrodes connected with contacts, by means of brackets 8 on the H-shaped discharge vessel support 5 are attached.
  • the H-shaped discharge vessel support 5 has the edge of its plate 4 a collar 9 extending in the direction of the envelope piston 2 with hook-shaped Formations 10, which in an at least partially circumferential groove 11 engage on the inner wall of the envelope piston 2. This makes one for the non-detachable connection between the H-shaped discharge vessel support 5 and envelope piston 2 created.
  • hook-shaped Formations 10 of the collar 9 By the interlocking of four hook-shaped formations 10 of the collar 9 in corresponding groove sections 11 in the region of the neck of the envelope piston 2 is an anti-rotation device realized between envelope bulb 2 and discharge vessel support 5. This causes that no forces act on the mechanical connection ensuring hook-shaped training arise and are therefore protected from damage.
  • Grooves and hook-shaped Formations are arranged in a 90 ° symmetry. In order to it is ensured that after placing the envelope piston 2 at the latest after a 90 ° turn both parts are in the joining position and then be connected to each other by application of the joining force. This is advantageous during assembly.
  • the low-pressure discharge lamp 1 also essentially has one cylindrical base 12 with a housing 13 and schematically Connection contacts 14 shown. Inside the housing 13 there is a mounting plate 15 perpendicular to the lamp axis, which as Circuit board is formed. On the side facing the discharge vessel 3 Conductor tracks are formed on the circuit board and on the discharge vessel 3 facing away are the circuit elements of a ballast arrangement 16 (shown schematically) attached.
  • the housing 13 of the base 12 is with the discharge vessel support 5 for the layman also non-releasable hook-shaped training 17 further annular collar 18 on the side facing the base 12 of the Plate 4 connected, the hook-shaped formations 17 in at least one partially circumferential annular groove 19 in the inner wall of the lateral surface of the housing 13 engages.
  • Both collars 9, 18 point parallel to the axis of symmetry of the H-shaped support 5 several distributed over the circumference narrow slots 20 that extend to the plate 4 and wider slots 21, in the corresponding ribs 22 on the inner lateral surface on the neck of the envelope piston 2 and engage on the base housing 13.
  • the narrow slots serve for segmentation of the hook-shaped formations and for reduction or adjustment of the joining force.
  • the wide slots serve as a connection with the ribs also to implement an anti-rotation lock between Base 12 and discharge vessel support 4 and for the correct alignment of the Contact elements in the brackets 8 to the corresponding contacts on the top of the mounting plate 15.
  • the hook-shaped formations on the collars 9 and 18 are realized in such a way that their projection onto the plane perpendicular to the lamp axis has no overlap has. This has the advantage of being a slide-less tool for spraying of the discharge vessel carrier 5 can be used.
  • FIG. 2 shows a low-pressure discharge lamp according to the invention, with a Reflector 21.
