Abstract (en)

An electrical circuit is disclosed in which a constant current is passed through a plurality of sockets connected in series. Selected ones of a corresponding plurality of plugs are insertable into and removable from the sockets. The plugs are connected to LED light sources, and the sockets are arranged to form a short circuit when plugs are removed therefrom, thereby to allow remaining LEDs to be powered. The circuit may form part of a coloured lighting system.
