Light guide optical cable, light guide communication composite optical cable and lighting system

Abstract

The invention discloses a light guide optical cable, a light guide communication composite optical cable and a lighting system, and belongs to the technical field of communication optical cables, the light guide optical cable comprises at least one light guide unit used for light transmission, at least one optical fiber unit used for communication signal transmission, and an outer sheath wrapping the peripheries of the light guide unit and the optical fiber unit; the light guide unit comprises a first core layer, a second core layer and a third core layer, the refractive index of the first core layer is higher than that of the second core layer, and a scattering core with the refractive index different from that of the third core layer is arranged in the third core layer. According to the light guide communication composite optical cable, under the condition that open fire and electric power are not introduced, the illumination light source is arranged at the end of the optical cable, light in the illumination light source is led out to a specific area, the corresponding area is lightened through the light guide unit and the illumination system, the structure of the optical cable is simple, and the problems of explosion and the like cannot be caused in a closed area; network supply to a closed area can be completed, and lighting work can be completed while safety problems are not caused.

Description

technical field [0001] The invention belongs to the technical field of communication optical cables, and in particular relates to a light guiding optical cable, a light guiding communication composite optical cable and a lighting system. Background technique [0002] Fire and explosion accidents are major personal and equipment accidents. Fires and explosions caused by electrical appliances account for a large proportion of piston and explosion accidents, second only to the number of accidents caused by open flames. In our industrial production and daily life, there are often scenarios where it is necessary to avoid the generation of electric sparks, such as in mines, dust-filled processing plants, inflammable and explosive materials transportation and storage environments, etc. [0003] In the above scenarios to avoid electric sparks, most of them belong to relatively closed places, but they also have lighting requirements and communication requirements. During the opening...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned scenarios to avoid electric sparks, most of them belong to relatively closed places, but they also have lighting needs and communication needs, and electric sparks are easily generated during the opening and closing process of lighting appliances, which is likely to cause fire and explosion accidents

For the special scene of avoiding electric sparks, it is mainly realized by explosion-proof lamps at present, but it still cannot completely avoid the generation of electric sparks, and explosion accidents occur from time to time
