Title:
EXPLOSION-PROOF LIGHTING SYSTEM
Document Type and Number:
Japanese Patent JP2017174594
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an explosion-proof lighting system which is safe and produced at low cost.SOLUTION: A lighting device 2 is provided to a fire-prohibited region 1, and a light source device 4 is provided to a non-fire-prohibited region 3 away from the fire-prohibited region 1 at a distance from the lighting device 2, in which the light emitted from the light source device 4 is guided to the lighting device 2 by an optical fiber 5. A light source 6 made of a light emission diode or the like is provided to the light source device 4, the optical fiber 5 being composed of a bind of a plurality of naked optical fibers 11. With each of the bound naked optical fibers 11 being separated into a single fiber, for example, on an emission side of the optical fiber 5, each of the naked optical fibers 11 are fixed in the lighting device 2 with spaced apart from each other. The light generated by an operation of the light source device 4 and transmitted to the optical fiber 5 is emitted from a light emission end of the naked optical fibers 11 provided with spaced apart from each other per a single fiber, and irradiated on a lighted space region of the fire-prohibited region 1 through the lighting device 2 having a light diffusion member (acryl sphere 18 or the like).SELECTED DRAWING: Figure 1
