Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tunnel illumination equipment capable of implementing a supervisory control of a substation on radio without providing a cable even in a huge tunnel. SOLUTION: A base station 11 outputs a control instruction from a radio transmitting unit 13 to a plurality of substations 12 disposed in a tunnel. The individual substations 12 receive the control instruction from the transmitting unit 13 of the base station 11 on radio at a built-in transmitting and receiving unit 15, and operates in accordance with the control instruction. Therefore, a control wire for transmitting the control instruction to the substation 12 becomes unnecessary so that the cost is reduced. COPYRIGHT: (C)2005,JPO&NCIPI
