Description

  The present invention relates to a cable that emits light outward.

  Cables are used to supply power from outside to ships docked at the quay or parked vehicles. Such a cable is often used in an environment where the surrounding lighting is inadequate, and the use of a so-called shining cable is preferred for safety reasons.

  A conventional cable of this type is disclosed in Patent Document 1. The cable includes a conductor, an insulating endothelium covering the outer periphery of the conductor, a shielding layer covering the outer periphery of the insulating endothelium, an insulating outer sheath covering the outer periphery of the shielding layer and containing a power storage material, and an insulating outer sheath. It is comprised from the protective layer which covers the outer periphery of.

  According to this conventional example, when the power storage material in the insulating sheath receives light such as sunlight or a fluorescent lamp, light is emitted even at night by the stored energy. Therefore, the visibility of the cable at night is high. However, in the daytime or the like, when light irradiation cannot be obtained, light is not emitted at night, and light is not emitted when the stored energy is exhausted.

  Therefore, as a conventional cable that can emit light at night even when light irradiation cannot be obtained in the daytime or the like, there is one disclosed in Patent Document 2. This cable is composed of a conductor and a light-emitting resin layer that covers the outer periphery of the conductor and contains a light-emitting material that emits light by an electric field.

  According to this conventional example, if an electric field is generated in the light emitting resin layer, light is emitted even at night, and the visibility of the cable at night is high.
