<P>PROBLEM TO BE SOLVED: To prevent electrification of a user, and maintain appearance of a system installment site by a low-cost constitution in a duct type illumination system. <P>SOLUTION: The duct type illumination system 1 includes: a duct 2; an illumination fixture 4 slidably supported by this duct 2; and a power-feeding part 5 to supply electric power to a power-receiving part 41 of the illumination fixture 4. The duct 2 has an aperture 21 in order to support the illumination fixture 4, and is mounted so that a side opposite to this aperture 21 faces architectural base material P side. The power-feeding part 5 has a constitution of feeding power contactlessly to the power-receiving part 41 by electromagnetic induction, and is arranged on the opposite side to this aperture 21. Since the illumination fixture 4 is supported by the aperture 41 of the duct 2 and the power-feeding part 5 is arranged on the opposite side to the illumination fixture 4 by having the separated duct 2 in between, wiring for a power source to the power-feeding part 5 can be arranged so as not to be exposed from a building. <P>COPYRIGHT: (C)2011,JPO&INPIT |
