The invention relates to an uninterruptible power supply, in particular a control device for uninterruptible power supply for street lighting, which has a plug-in igniter and a spare circuit for the automatic elimination of errors.

An ignitor of conventional street lights has a light sensor for detecting the brightness of the environment and an electromagnetic switch for controlling the illumination of a street lamp. By detecting the brightness of the environment and operating the electromagnetic switch, street lighting can be automatically turned on or off. However, the ignitor and the switch each have a single circuit. If the switch is damaged by the effect of a lightning strike or a surge current on the circuit, it must be gradually checked, repaired or replaced. In addition, the assembly of an ignitor by electric welding nowadays usually leads to high repair and maintenance costs.

The invention is therefore an object of the invention to provide a control unit for uninterruptible power supply for street lighting, which has a backup circuit.
