A lighting fixture has a housing, a socket provided to the center portion of the housing, a reflector attached to the inner surface of the housing, and a lamp screwed into the socket. An annular band-shaped sealing plate, a disc-shaped cover plate, and an annular band-shaped locking plate are sequentially placed on the upper end of the housing, and the locking plate is placed on the periphery of the cover plate and is locked to the housing. A groove is defined in the inner surface of the skirt portion bent from the locking plate, the sealing plate is detachably fitted into the groove, an engagement projection is formed on the inner edge of the locking plate, and the cover plate is locked to the engagement projection, whereby a space is defined between the cover plate and the sealing plate. The locking plate and the cover plate have different colors. |
