Abstract

Apparatus for controlling the energization of at least two groups of lamps each of which is in series with a thyristor wherein the control signal for all thyristors is generated in a common control signal generator. An auxiliary control signal generator is provided for each lamp group to control the lamp energy in the event of a failure of the main control signal.
