1. A parallel redundant integrated-circuit system, comprising:

  • a backplane;

    a common input connection;

    a common output connection;

    a first active circuit comprising one or more first integrated circuits disposed on the backplane, the first active circuit comprising an input directly connected to the common input connection and an output directly connected to the common output connection, wherein each first integrated circuit of the one or more first integrated circuits comprises a separate, independent, and distinct substrate; and

    a second active circuit comprising one or more second integrated circuits disposed on the backplane, the second active circuit redundant to the first active circuit and comprising an input directly connected to the common input connection and an output directly connected to the common output connection, wherein each second integrated circuit of the one or more second integrated circuits comprises a separate, independent, and distinct substrate,wherein each input of the first active circuit is directly electrically connected to a corresponding redundant input of the second active circuit and each output of the first active circuit is directly electrically connected to a corresponding redundant output of the second active circuit,wherein the one or more second integrated circuits are separate and distinct from the one or more first integrated circuits so that the first active circuit and the second active circuit are substantially identically electrically connected to the common input connection and to the common output connection and the first active circuit and the second active circuit are operable in parallel to provide a substantially identical output, andwherein the first active circuit comprises a first light emitter and a first driver circuit that controls the first light emitter and the second active circuit comprises a second light emitter and a second driver circuit that controls the second light emitter.
