The invention relates to a furnace () for producing a discharge lamp, comprising an outer furnace wall. It is characterized by a hollow body () that surrounds the outer furnace wall and is provided to receive discharge vessel parts () and joints of the same to a discharge vessel () for the discharge lamp. The hollow body () further comprises a discharge gas supply () for flooding with a discharge gas such that a discharge vessel () provided in the hollow body () is filled with the same. The invention further relates to a production method for discharge lamps comprising such a furnace ().

Furnace and method for producing a discharge lamp

The present invention relates to a discharge lamp with a floor plate and a roof plate, which is designed for dielectrically impeded discharge, with at least two electrodes of different polarity being allocated to the sections of the discharge space, which is divided by rib-like support elements, with the electrodes located at a distance from the longitudinal support elements.

The present invention relates to novel discharge structures for dielectric barrier discharge lamps, in which discharge electrode sections, which are associated with the individual discharges, of the respective electrode strips overhang adjacent sections of the electrode strips.

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 plateis, 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 plateoutside the first discharge vessel plate

Discharge lamp with stabilized discharge vessel plate

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.

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 plateis, as it were, of two-fold design, specifically as a first discharge vessel platewith an external electrode set and, in addition, as a stabilizing plateoutside the first discharge vessel plate

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.

The invention relates to the capacitive modulation of the field distribution in a silent discharge lamp, by a structured, electrically conductive devicefor definition of preferred locations for discharge structures in the lamp

Discharge lamp having capacitive field modulation

A flat fluorescent lamp () has a discharge vessel () having a base plate (), a top plate () and a frame () which are connected to one another in a gas-tight fashion by means of solder (). Structures resembling conductor tracks function in the interior of the discharge vessel as electrodes (), in the feedthrough region as feedthroughs, and in the external region as external supply leads (). Flat lamps of the most different sizes can thereby be produced simply in engineering terms and in a fashion capable of effective automation. Moreover, virtually any electrode shapes can be realized, in particular optimized with regard to a uniform luminous density with a reduced drop in luminous density towards the edges of the flat lamp. At least the anodes () are covered in each case with a dielectric layer (). The lamp () is preferably operated by means of a pulsed voltage source and serves as background lighting for LCDs, for example in monitors or driver information displays.
