PURPOSE:To reduce the cost and simplify and quicken the installation of a photo-control member to a lighting fixture body by forming an inner frame in a single piece with a lower photo-control member, and engaging a detention part with a detent part of the lighting fixture body in such a way as capable of disengaging as desired. CONSTITUTION:An inner frame is formed in a single piece with a lower louver member 18. When louver 15 is mounted to a lighting fixture body 12, first an upper louver member 17 is secured to the mounting member 12b of the fixture body 12, and a hooking part 23 at the inner frame formed in a single piece with the lower louver member 18 is detained with the hooking receipt part 24 of the fixture body 12. The free end of the lower louver member 18 is revolved with this hooking part 23 as fulcrum add engaged with the hooking receipt part 2-1 of the fixture body 12 in such a way as capable of disengaging as desired. This permits the lower member 18 to be butted to the upper member 17 correctly, and mounting on the fixture body 12 is made properly. Thereby, the cost is reduced, and the installation of photo-control member 15 to the fixture body 12 can be performed simply and easily. |
