PURPOSE:To eliminate the trouble with attachment of a reflector and improve the appearance of the luminaire by providing the rotation preventing rib of the reflector with both a recessed portion into which a circular presser bar can be inserted at the fixing position of the reflector, and a channeled portion into which a light regulating member supporting frame can be inserted by rotation of the supporting frame in its axial direction through predetermined degrees. CONSTITUTION:The inner face of the luminaire main body 1 is provided with three ribs 42 each continuously protruding from front face side to back face side thereof. The ribs 42 are provided with both a recessed portion 43 into which a circular-line-shaped presser spring 28 can be inserted at the fixing position of a reflector 22, and a channeled portion 44 into which the protruding portion 34 of a light regulating member supporting frame 30 can be inserted by rotation of the light regulating member supporting frame 30 in the direction of the axis of the supporting frame 30 through predetermined degrees. Thus, after the light regulating member supporting frame 30 is mounted to the inside of the front face opening of the luminaire main body 1, it is rotated in the direction of the axis of the tube of the supporting frame 30, whereby it is fixed to the luminaire main body 1 and also the light regulating member supporting frame 30 can hide engaging portions 29, 29 provided at both ends of the leg portion 30 of a cap 26. It is thus made possible to obtain a luminaire of much workability and good appearance. |
