The present invention concerns light sources. The light source, according to the inventiion, is essentially characterized in that it comprises two potential terminals (1, 2) a transformer coil having a primary with two windings (9, 12) and a secondary (16), a transistor (300), whereby the voltage terminal (1) is in turn connected to the transistor base (22), whose collector (23) is connected to the primary coil's second winding and whose emitter (24) is connected to the terminal (2), whereby a current capacitor (25) connects the second winding (12) to the terminal (2), a potentiometer (400) connects the terminal (1) to the capacitor (25), at the common point between the capacitor and the second winding, and whereby a sealed enclosure (19) with two electrodes (20, 21) contains a gas, said electrodes being connected to the secondary coil winding (16). Application: the invention may be used advantgeously in lighting of all types, industry, publicity, the home and the like.

2026319 9009088 PCTABS00101 La présente invention concerne les sources lumineuses. La source lumineuse selon l'invention se caractérise essentiellement par le fait qu'elle comprend deux bornes (1, 2) de potentiel, un bobinage de transformation ayant un primaire à deux enroulements (9, 12) et un secondaire (16), un transistor (300), la borne de potentiel (1) étant reliée au premier enroulement (9) du primaire, qui est relié à la base (22) du transistor, dont le collecteur (23) est relié au second enroulement du primaire et dont l'émetteur (24) est relié à la borne (2), une capacité de charge (25) reliant le second enroulement (12) à la borne (2), un potentiomètre (400) reliant la borne (1) à la capacité (25), au point commun entre la capacité et le second enroulement, une enceinte étanche (19) à deux électrodes (20, 21) contenant un gaz, ces deux électrodes étant reliées à l'enroulement (16) du secondaire. L'invention trouve une application avantageuse dans l'éclairage de tout type, dans l'industrie, la publicité, le domestique, etc.
