LUMINAIRE WITH ELEVATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a luminaire with an elevation device capable of simplifying structure and securing safety in an elevated position.

SOLUTION: A light fixture 2 having a conical configuration is suspended at an upper end part 2b by means of a single wire 8. An elevation unit 3 winds/unwinds the wire 8 to move the light fixture 2 upward/downward. A fixture main body 1 is provided with a housing part 1a housing the light fixture 2 in the elevated position of the light fixture 2 and a guide part 1b, which guides the upper end part 2b of the light fixture 2, in the upper part of the housing part 1a. A pair of power receiving parts 7 are protruded at the different distances from the upper face center of the upper end part 2b of the light fixture 2, while a groove type power receiving part 13 is arranged in the guide part 1b so that a pair of power receiving parts 7 can be brought into contact by elevation of the light fixture 2.
