According to the invention, a certain number of discharge tubes 18a, 18b, 18c are controlled according to a predetermined or random cycle, the tubes emitting radiation of various colours in order to create a number of hues which is greater than the number of tubes. Especially in order to permit immediate lighting of each of the tubes, control means 24 operating according to the principle of low-voltage and high-frequency current chopping are used.
