Abstract

According to the invention, a dielectrically obstructed discharge is either superimposed or series-connected in a discharge chamber (3) on or to a conventional, pulsed, dielectrically unobstructed discharge generated between two electrodes (5, 6).
On the one hand the colour location of the lamp (12) can be deliberately altered and on the other ~~~ operating voltages of the discharges can be reduced via the ratio between the electric powers of the two discharges. The degree to which the colour location can be affected may be reinforced by a luminophore coating (4).
To achieve the operation of the invention, the discharge chamber (3) has at leat one additional electrode (13, 14) which is separated from the discharge by a dielectric layer (3).
