  • this cover can also be designed as a cap for the base housing.
  • the plate of the H-shaped discharge vessel carrier is advantageously designed circular.
  • the fastening of the discharge vessel is simple if the plate of the discharge vessel carrier has two apertures or half-shell-shaped depressions for receiving the ends of the discharge vessel.
  • 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 Sockelkitt or adhesive to the plate.
  • the plate points advantageous around the openings or half-shell-shaped depressions around a retaining edge for receiving the Sockelkitts or adhesive, wherein the retaining edge in the case of breakthroughs advantageously mounted on the side facing the base of the plate and in the case of half-shell-shaped recesses on the cover part facing side of the plate is.
  • the attachment of the discharge vessel to the discharge vessel support may also be effected by means of a depression into which a part of the discharge vessel, such as a discharge vessel, is attached. a bend is made, done. This type of attachment may also be useful in addition to the fixation of the two ends of the discharge vessel, especially if it is a long and multiply bent discharge vessel.
  • the plate further has on the side facing the base preferably mounts for contacts for electrical connection of the power supply lines with the electrical connections of the ballast on the mounting plate.
  • 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 cost-effective electrical connection between the power supply lines of the discharge vessel and the terminals of the ballast assembly is made on the mounting plate.

  • Each collar advantageously has between 2 and 8 hook-shaped formations.
  • the hook-shaped formations have a width of between 1 and 30 mm, depending on the socket housing diameter, and are laterally offset relative to each other, so that the projections of the hook-shaped formations do not overlap in a plane perpendicular to the lamp axis.
  • the hook-shaped formations on the two collars are further divided by reaching to the plate narrow slits in several segments. This segmentation leads to a reduction in the joining force.
  • the number and width of the segments are matched to one another in such a way that the strength values required in the relevant standards are maintained and the joining forces are within a range that is easily manageable even when mounted by hand.
  • On the plate openings may additionally be provided for the engagement of holding tools.
  • the H-shaped support is made of plastic, wherein the material is advantageously transparent.
  • the cover part is preferably made of plastic, wherein in a design of the cover as an envelope this can consist of a glass bulb with an attached plastic edge.
