Abstract
A shield for a bulb of a lighting base includes an upper portion for at least partially encircling a bulb and means for coupling the upper portion to a lighting base. Another shield includes a first portion and a second portion. The first portion at least partially encircles and protects a bulb such that if a lighting base, a bulb and the shield are dropped on a surface, a bulb cannot come into contact with a surface. The second portion is for coupling the shield to a lighting base. The first portion has a length and at least one side of the first portion, as defined along the length of the first portion, is open to the bulb.
Claims12
A shield for a bulb of a cylindrical lighting base comprising:
- an upper portion for only partially encircling a bulb, said upper portion enclosed on one side and open on an opposite side, and having a bottom end;
- and
- an upstanding cylindrical base portion connected directly to the bottom end of the upper portion, said upstanding cylindrical base portion for coupling the upper portion to the cylindrical lighting base and for suspending the upper portion around the bulb so that it does not come into contact with the bulb, said upstanding cylindrical base portion being sized such that it substantially surrounds and covers a length of the cylindrical lighting base and seats on a circumference of a top end portion of the cylindrical lighting base,
- wherein the upstanding cylindrical base portion is substantially tubular and a longitudinally extending slit extending along an interior or an exterior length of the upstanding cylindrical base portion that permits the upstanding cylindrical base portion to flex open in order to surround the length of the cylindrical lighting base,
- and the upstanding cylindrical base portion is sized with a dimension that is smaller than the dimension of the top end of the cylindrical lighting base to provide a tension fit that is provided by an inner dimension that is smaller than an outer dimension of the top end of the cylindrical lighting base such that the tension fit of the upstanding cylindrical base portion provides for the upstanding cylindrical base portion to be self-supporting on the upper portion on the cylindrical lighting base, with the longitudinally extending slit of the upstanding cylindrical base portion permitting the upstanding cylindrical base portion to flex around the cylindrical lighting base,
- wherein the upstanding cylindrical base portion is coupled directly to the upper portion by a single rib that extends perpendicular to a length of the upper portion.

- wherein the upper portion has a truncated cone shape resembling a lamp shade, with a wider portion of the truncated cone shape being positioned at the bottom end of the upper portion and a narrower portion of the truncated cone shape being positioned at an upper end of the upper portion, and
- further comprising an open rib structure joining a top end of the truncated cone shape together.
