Abstract
Abstract A ceiling fan is disclosed which is suspended from the ceiling in a conventional manner, and includes a plurality of fan blades secured to a rotatably driven outer portion of the motor assembly. The motor assembly is surrounded by a housing including top and bottom plates in a clamped engagement with an annular translucent panel, disposed peripherally between the plates, and including an annular fluorescent light bulb disposed within the housing in a surrounding relation to the motor assembly, including a support structure to hold the light bulb in a generally central position between the plates.
