Abstract

PROBLEM TO BE SOLVED: To improve workability for the failure repair of a light source, a replacement work, and the like by forming a light guide transmitting light of a lower lens, a lower reflection means, an upper reflection means, and an upper lens. SOLUTION: A light guide 13 is provided between a radiative means 11 provided on the ground and respective floodlights 12 along the legs, and the like of a multi-storied building 1. The power supplied from a power supply means 6 is fed to a radiative means 11 via a distribution line 4 and an insulating transformer 5. After the light radiated from the radiative means 11 is converted into the parallel light via the lower lens 13a, and the lower reflection means 13b of the guide 13, the light is reflected and is guided upward. The light is guided to the flood lights 12 via the upper reflection means 13d, and the upper lens 13e of the guide 13, and is radiated toward the periphery as the diffusing light. Since the radiative means 11, a light source, is provided on the ground, workability in the maintenance, the replacement, and the like of the radiative means 1 is improved, and the working cost is also reduced.
