Abrégé

Disclosed is a halogen light bulb comprising a carbide-containing filament and lead-in wires which retain the filament. A filament is vacuum-tightly introduced into a bulb along with a filling. The filament is provided with a metal carbide whose melting point is greater than that of tungsten, the carbon concentration of the metal carbide being smaller than that corresponding to complete carburization, i.e. carburization resulting in the production of metal carbides in which the number of metal atoms and the number of carbon atoms are at an integer stoichiometric ratio relative to each other.

Abrégé

The invention relates to a circuit arrangement for setting a colour locus of a light source arrangement comprising a first light source (2 to 4; 2’ to 4’; 2’’ to 4’’), which is formed for generating a light signal of a first colour locus, and at least one second light source (2 to 4; 2’ to 4’; 2’’ to 4’’), which is formed for generating a light signal of a second colour locus. The first light source (2 to 4; 2’ to 4’; 2’’ to 4’’) is electrically connected to a first resonant circuit, which has a first resonant frequency, and the second light source (2 to 4; 2’ to 4’; 2’’ to 4’’) is electrically connected to a second resonant circuit, which has a second resonant frequency. A power supply unit (6; 6’), which is electrically connected to the resonant circuits, is formed for supplying power to the two light sources (2 to 4; 2’ to 4’; 2’’ to 4’’). By changing a value of an initial operating parameter of the power supply unit (6; 6’) the resonant circuits can be controlled in such a way that the intensities of the light signals of the light sources (2 to 4; 2’ to 4’; 2’’ to 4’’) can be altered individually and the colour locus of the light source arrangement can be set. The invention also relates to a method for setting a colour locus of a light source arrangement.
