Abstract

A high alternating voltage between 10 to 40 kV is applied to at least two distinct tungsten electrodes enclosed in a halogen filled quartz tube. To compensate for the absence of a tungsten filament by firing the lamp at high voltage. The two electrodes are placed at each end of the quartz tube the applied high voltage is controlled by a voltage regulator and the lamp has also a frequency regulator. A variant of the lamp is characterized by a twin high or very high electrical supply inside the quartz tube, which has a square, flattened or cylindrical shape. The electrical supply is activated by a filament electrode fed at 220 volts and another electrode or plate fed at high or very high voltage. The independent electrodes are contained in the quartz tube.

Description

Dans le domaine de l'éclairage, il est utilisé des lampes dont l'additionIn the field of lighting, lamps are used whose addition

Les lampes utilisant du gaz de type halogène, sont munies d'un filament qui permet  gas halogen type, allows to have a gradation of the quality of light with an infinity of light intensity settings The presence of alkyl halide allows this performance. Lamps using halogen gas, are provided with a filament which allows

La présente invention procède à la suppression du filament dans le tube de la lampe. L'absence du filament ne permet plus l'amorçage dans les condition initiales de fonctionnement. Le présent procédé compense l'absence du filament par la mise en oeuvre d'une haute tension, qui permet l'amorçage de l'éclairage du gaz et surtout, un nouveaux type de  The present invention removes the filament from the lamp tube. The absence of the filament no longer allows priming in the initial operating conditions. The present process compensates for the absence of the filament by the use of a high voltage, which allows the ignition of the gas lighting and above all, a new type of

Un appareil est réalisé conformément au procédé, caractérisé en ce que au moins deux électrodes en tungstène distinctes sont placées à chaque extrémité du tube obturé. Le tube en quartz est chargé d'un gaz de type organo-halogèné, à l'intérieur du tube. Il est appliqué une haute tension alternative aux électrodes, voire une très haute tension, qui est réglable par un' gradateur de tension. Un gradateur de fréquence est également installé sur le circuit d'alimentation des électrodes.La lampe est tenue dans un boitier réalisé par l'homme de l'art, aux normes électriques. La régulation de la tension est en relation avec le volume du tube et les caractéristiques diélectriques du gaz, et la position des électrodes. La tension de seuil d'amorçage est ainsi parfaitement établie. Les tensions  An apparatus is produced in accordance with the method, characterized in that at least two separate tungsten electrodes are placed at each end of the closed tube. The quartz tube is charged with an organo-halogenated gas, inside the tube. An alternating high voltage is applied to the electrodes, or even a very high voltage, which is adjustable by a 'voltage dimmer. A frequency dimmer is also installed on the supply circuit of the electrodes. The lamp is held in a case produced by a person skilled in the art, in accordance with electrical standards. The regulation of the voltage is related to the volume of the tube and the dielectric characteristics of the gas, and the position of the electrodes. The ignition threshold voltage is thus perfectly established. The tensions
