Abstract
A U-shaped fluorescent lamp has a protective assembly that includes a two-part loop unit and a pair of leg units. Each loop part is formed of a transparent or translucent non-frangible polymeric material, is semi-cylindrical in cross section and is shaped in plan to match the shape in plan of the loop portion of the glass tube of the lamp. The loop parts are coextensive, engage each other along mating edges at a tongue and groove joint, and are joined to each other along the mating edges solely by mechanical couplings. Each leg unit is a straight tube of a transparent or translucent non-frangible polymeric material, is cylindrical in cross section, and is joined at one end to one end of the loop unit by a telescopic joint in which the end portion of the straight tube receives a cylindrical end portion of the loop unit and is joined at the other end to the terminal end cap of the lamp by a joint that includes an adhesive.
