Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A lighting fixture for indirect lighting applications comprising: a mounting member in the form of an elongated generally U-shaped extrusion of reflective material having a base panel and right angularly extending side panels having inner and outer surfaces, each of said side panel inner surfaces being formed with an elongated groove extending therealong proximate and equi-distant from said base panel, and being formed as diverging angular surfaces proceeding outward from adjacent said respective elongated grooves; an insert strip in the form of an elongated panel having a plurality of spaced holes formed therealong and including ridge means on each side for mating engagement in the respective base member grooves; and a light strip having plural lamp assemblies mounted thereon in spacing similar to said insert strip spaced holes, said light strip being disposed between the insert strip and mounting member base panel and extending respective lamp assemblies through said spaced holes.
Claim 2
Dependent Claim
151 words
A lighting fixture for indirect lighting applications comprising: a mounting member in the form of an elongated generally U-shaped extrusion of reflective material having a base panel and right angularly extending side panels having inner and outer surfaces, each of said side panel inner surfaces being formed with an elongated groove extending therealong proximate and equi-distant from said base panel, and being formed as diverging angular surfaces proceeding outward from adjacent said respective elongated grooves; an insert strip in the form of an elongated panel having a plurality of spaced holes formed therealong and including ridge means on each side for mating engagement in the respective base member grooves; and a light strip having plural lamp assemblies mounted thereon in spacing similar to said insert strip spaced holes, said light strip being disposed between the insert strip and mounting member base panel and extending respective lamp assemblies through said spaced holes.
Claim 3
Dependent Claim
73 words
A lighting fixture as set forth in claim 1 wherein said insert strip is further characterized in that: said insert strip elongated panel includes opposite side right angle side panels, each of which has said ridge means formed thereon, said side panels being adapted for insertion toward the base panel when the insert strip is in secured position thereby to define a space between the elongated panel and the mounting member base panel.
Claim 4
Dependent Claim
37 words
A lighting fixture as set forth in claim 1 wherein said light strip is further characterized in that: said light strip includes a pair of electric conductors with each of said plural lamp assemblies connected in parallel.
Claim 5
Dependent Claim
39 words
A lighting fixture as set forth in claim 3 wherein: said plural lamp assemblies each consist of a lamp socket and lamp that is removable and replaceable while said mounting member and insert strip remain in ridge means-to-groove assembly.
Claim 6
Dependent Claim
44 words
A light fixture as set forth in claim 1 wherein: a portion of at least one mounting member side panel is uniformly removed along the length thereof in order to increase the amount of both direct and reflected light external to said mounting member.
Claim 7
Dependent Claim
39 words
A lighting fixture as set forth in claim 1 wherein each of said light strip plural lamp assemblies further comprises: a lamp socket for secure insertion through said spaced holes; and a lamp removeably inserted in said lamp socket.
