Abstract
Abstract The fluorescent lampholder includes a first compressible end for receiving one end of the lamp and a second fixed end for receiving the other end of the lamp. Mounting clips are provided on each of the lamp-holding ends to secure each of the ends in a base panel. Extension tabs are joined to mounting clips on the compressible end and on the fixed end. The tabs are adapted to receive and support a grounding wire or spring for the fluorescent lamp therebetween.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
In a fluorescent lampholder of the type having first and second lamp receiving ends, each of said ends having a pair of electrically conductive mounting clips connected thereto and adapted to mount each of said ends on a base panel and an electrically conductive grounding strip, an improvement comprising, in combination: a first electrically conductive tab secured and electrically connected to one of said mounting clips on said first end, and a second electrically conductive grounding tab secured and electrically connected to another of said mounting clips on said second end, said conductive clips adapted to support said grounding strip therebetween in fixed relation to said lamp.
Claim 2
Dependent Claim
107 words
In a fluorescent lampholder of the type having first and second lamp receiving ends, each of said ends having a pair of electrically conductive mounting clips connected thereto and adapted to mount each of said ends on a base panel and an electrically conductive grounding strip, an improvement comprising, in combination: a first electrically conductive tab secured and electrically connected to one of said mounting clips on said first end, and a second electrically conductive grounding tab secured and electrically connected to another of said mounting clips on said second end, said conductive clips adapted to support said grounding strip therebetween in fixed relation to said lamp.
Claim 3
Dependent Claim
28 words
The improvement as set forth in claim 1 wherein said first and second grounding tabs are integral with said one mounting clip and said another mounting clip respectively.
Claim 4
Dependent Claim
55 words
The improvement as set forth in claim 1 wherein said first and second grounding tabs have eyelets defined thereon and wherein said grounding strip includes a first hook connected to one end of said strip and a second hook connected to the other end of said strip, said hooks adapted to fit into said eyelets.
