Embodiment Construction

[0030] Exemplary embodiments of discharge lamps are explained below. As already stated at the outset, however, the application of the invention is not restricted to such discharge lamps or high-pressure discharge lamps, but can in principle be used in all lamp types in which the film seal serves as the current feedthrough.

[0031] figure 1 A partial view of a high-pressure discharge lamp 1 (also referred to as burner) is shown. The high-pressure discharge lamp has a discharge vessel 2 , on the end sections of which a rod 4 is formed in each case, on which the interior of the discharge vessel 2 is sealed off by a seal. An ionizable filling consisting, for example, of high-purity xenon gas and various metal halides is contained in the interior 6 of the discharge vessel 2 . Two electrodes protrude into the interior 6 between which a discharge arc is distributed during lamp operation. figure 1 The electrodes, not shown, are each supported by electrode rods 8 , one end section ...

Abstract

The invention relates to a method for producing a melting film, a melting film produced according to such a method, and a lamp having such a melting film. According to the invention, said melting film is separated from a film stock in that a weak zone is previously formed.

Description

technical field [0001] The invention relates to a method for producing a sealing film according to the preamble of claim 1 , a film produced according to this method according to the preamble of claim 9 , and A lamp with such a film according to the preamble of claim 11 . Background technique [0002] Lamps of this type, for example halogen lamps, discharge lamps, high-pressure discharge lamps, have a lamp vessel (also referred to as a burner) in which a luminous means such as a filament or (in the case of a discharge lamp) electrodes are accommodated. Depending on the lamp type, the power supply associated with the luminaire extends, for example, through an extrusion, a seal or a sealed extrusion of the lamp vessel. These embedding methods are to be understood here as synonymous and only the seal is also mentioned below. The direct sealing of feeds, usually made of molybdenum or tungsten, into glass (quartz) is difficult to achieve with the necessary tightness, since the ...
