Abstract
A device for supplying at least two LED chains with electricity detects and then signals an interruption in the current path through the LED chains. A sub-device, in the event of a short circuit of an LED within a first LED chain, brings about a detection and/or a subsequent signalling of an interruption of the current path within another LED chain of these at least two LED chains. The associated method comprises the steps of detecting the short circuit of an individual LED in a first LED chain and of interrupting, as a result, the flow of current through at least one other LED chain and subsequently detecting this interruption of the flow of current through the other LED chain by means of the interruption detection system already existing as required.
