<P>PROBLEM TO BE SOLVED: To provide a lighting apparatus which facilitates detachment of the lighting apparatus without incurring much cost and in which work efficiency is improved. <P>SOLUTION: The lighting apparatus 1 installed on a duct rail wired on the ceiling has: a power supply plug 12 fixed to the duct rail by a lever portion 121 in one end of the apparatus base body 11; and a locking unit 13 locking to the duct rail at the other end. The locking unit 13 has a projection portion 131 having elasticity to be engaged with the duct rail on both sides of the apparatus base body 11 viewed in longitudinal direction. The projection portion 131 has a first inclined face 131a for guiding the lighting apparatus so as to be easily attached when attaching the apparatus 1 to the duct rail, which becomes narrower the more it goes to the duct rail to be attached viewed in longitudinal direction, and a second inclined face 131b for guiding the lighting apparatus so as to be easily detached when detaching the apparatus 1 from the duct rail, which becomes narrower the more it goes to the one end side viewed from the side of attachment to the duct rail. <P>COPYRIGHT: (C)2007,JPO&INPIT |
