SOLUTION: An illumination appliance 2 is supported at a desired part of the pole 1, an inspection port 4 is provided near the lower end of the pole, and an opening/closing lid 5 is openably supported at the inspection port. A control circuit 6 is provided inside of the inspection lid, and an auxiliary lamp 8 is provided on an inspection lid to be visible from outside. The control circuit has a timer function. When a light source is not lit, the auxiliary lamp is lit. COPYRIGHT: (C)2004,JPO&NCIPI
