1. A passive luminescent cable, comprising:
a cable core and an outer sheath;
wherein,
the outer sheath is wrapped outside the cable core;
the cable core comprises a plurality of power wire cores, a ground wire core, an electromagnetic field energy collection wire core and a light strip;
the electromagnetic field energy collection wire core comprises a magnetic conducting wire core, and a plurality of first conductor wires;
the plurality of first conductor wires is wound outside the magnetic conducting wire core to form coils, and both ends of each of the plurality of first conductor wires are respectively connected to two electrodes of the light strip to form a loop;
the outer sheath and a protective sleeve of the light strip are made of a light-transmitting material; and,
the electromagnetic field energy collection wire core is arranged beside the plurality of power wire cores, wherein an accommodating gap is formed between every two adjacent power wire cores of the plurality of power wire cores, and the electromagnetic field energy collection wire core and the light strip are respectively placed in two accommodating gaps, or the electromagnetic field energy collection wire core and the light strip are placed in a same accommodating gap, the electromagnetic field energy collection wire core does not increase the diameter of the passive luminescent cable.
