Disposable reflectors for lighting fixtures

Claim 1

A pendant light fixture with a reflector means of the type having a base with a light source attached to and depending from the base, comprising: a thin, readily deformable foil insert formed with a reflective surface having the shape of an axially elongated surface of revolution configured to encircle the light source and directionalize light rays emitted therefrom; and attachment means for removably securing an upper end portion of said insert to the base, said means comprising means attached to the lower end of the fixture base and forming an annular, radial groove spaced radially outwardly of the light source, said insert being sized at said upper end portion to overlie said groove in close juxtaposition therewith when disposed with said upper end portion in radial alignment with said groove, a substantially circular, spring retainer engaging said insert on a surface thereof disposed oppositely of the surface confronting said groove and being resiliently biased radially inwardly of said groove, said upper end portion of said insert being deformed into said groove by said retainer thereby clamping said insert in firm assembly with the base, whereby said insert may be readily removed and replaced by moving said spring retainer against the bias thereof and outwardly of the groove to release said insert once the same has become soiled or otherwise ineffective to efficiently reflect the light rays emitted by the light source.
