Abstract
A lighting fixture, particularly a ceiling fixture adapted to surround a source of illumination, includes a horizontal mounting bracket with a set of upwardly open recesses formed in its upper edge. The bracket is preferably formed from a strip with a rectangular cross section, has overall a closed loop configuration, and is oriented with the recesses formed in a narrow edge surface of the strip. A set of translucent members are replacably assembled to the bracket without rivets or welding by a set of attachment members each have a hooked, upper end portion that seats in an associated one of the recesses. The seating is preferably snug and the hooked portion sandwiches the bracket below the recess to provide mechanical stability. The translucent member is preferably secured to the attachment member at a closed hole formed in the lower portion of the body by a conventional fastener that engages the hole and the translucent member.
