  • Publication number: 20070161317
    Abstract: A process for producing a discharge lamp, includes the following process steps: providing a discharge vessel, producing a paste for a functional layer from the components: pulverulent base material, polyalkylene carbonate as binder and solvent, forming the functional layer by applying the paste to at least part of the wall of the discharge vessel. The type of base material depends on the type of functional layer, such as for example phosphor layer, reflective layer or soldering glass layer. The use of a polyalkylene carbonate as binder allows the binder to be removed without leaving any residues at relatively low binder-removal temperatures and therefore allows efficient lamps to be produced.

  • Patent number: 7144288
    Abstract: A process for producing a discharge lamp which is designed for dielectric barrier discharges in which, during a filling step, before the discharge chamber is closed, a part of the discharge vessel is held in a raised position by a support element which is then at least partially softened, in order for the part which is being held in a raised position to be lowered. The support element lies outside the discharge chamber.

  • Patent number: 7144290
    Abstract: The invention relates to a new design of discharge vessel for a discharge lamp, in which dielectrically impeded discharges are to be generated. In this case, a discharge vessel plate 1, 9 is, as it were, of two-fold design, specifically as a first discharge vessel plate 1 with an external electrode set and, in addition, as a stabilizing plate 9 outside the first discharge vessel plate 1.

  • Patent number: 6976898
    Abstract: The invention relates to an improved method of production for a flat radiator discharge lamp designed for dielectrically impeded discharges, in which, during a filling step for the discharge vessel, a plate of the discharge vessel is jacked up on parts, later softening, of support elements in order to be lowered onto the other plate at a specific temperature. In this case, the support elements serve, in addition, to improve the mechanical stability of the finished flat radiator. According to the invention, only a small number of the support elements present in a relatively large number are used for the outlined function of holding up the plate.
