Abstract
Abstract A lighting fixture adapted to receive an elongated high intensity lamp is provided. The fixture includes a pair of socket assemblies spaced apart from each other within the fixture housing with each assembly including a ceramic socket housing adapted to nest in a base of material of high thermal conductivity. The ceramic housing is maintained in position by a spring which also urges the housing toward the other socket assembly to provide the necessary secure electrical connections between the sockets and the ends of the lamp which comprise the lamp terminals.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 words
A lighting fixture of the type adapted to receive an elongated lamp having terminals at the ends thereof, said fixture including: a fixture housing including a rear wall formed of a material having a high thermal conductivity and a pair of socket assemblies in said housing spaced apart from each other a distance substantially equal to the length of said lamp and adapted to secure said lamp in said position and provide electrical connections for said lamp through said terminals wherein at least one of said socket assemblies comprises: a socket base formed of a material of high thermal conductivity affixed to said housing in thermal conductive relationship, said socket base comprising a generally rectangular member formed integral with said rear wall and including surfaces thereon defiNing a nest having a raised forward end directed toward the other socket assembly and a top surface spaced above said fixture housing rear wall; a lamp socket housing formed of an electrically insulating material seated within said nest and containing a socket therein adapted to receive one end of said lamp; and spring means affixed to said fixture housing adapted to simultaneously urge said socket housing into said nest and bias said socket housing longitudinally toward the other socket assembly.
Claim 2
Dependent Claim
207 words
A lighting fixture of the type adapted to receive an elongated lamp having terminals at the ends thereof, said fixture including: a fixture housing including a rear wall formed of a material having a high thermal conductivity and a pair of socket assemblies in said housing spaced apart from each other a distance substantially equal to the length of said lamp and adapted to secure said lamp in said position and provide electrical connections for said lamp through said terminals wherein at least one of said socket assemblies comprises: a socket base formed of a material of high thermal conductivity affixed to said housing in thermal conductive relationship, said socket base comprising a generally rectangular member formed integral with said rear wall and including surfaces thereon defiNing a nest having a raised forward end directed toward the other socket assembly and a top surface spaced above said fixture housing rear wall; a lamp socket housing formed of an electrically insulating material seated within said nest and containing a socket therein adapted to receive one end of said lamp; and spring means affixed to said fixture housing adapted to simultaneously urge said socket housing into said nest and bias said socket housing longitudinally toward the other socket assembly.
Claim 3
Dependent Claim
86 words
The invention in accordance with claim 1 wherein said raised forward portion comprises wall means extending upwardly from the forward end of said member, said nest includes a recess extending downwardly from said top surface, said socket housing includes a depending bottom portion contoured to fit within said recess and a front portion contoured to abut against the socket base raised forward end, and said spring means simultaneously urges said socket housing depending portion into said recess and front portion against said socket base forward end.
Claim 4
Dependent Claim
39 words
The invention in accordance with claim 1 wherein said socket extends from the front portion of said housing and further comprising a cutout in said socket base forward end aligned with said socket and providing access to said socket.
Claim 5
Dependent Claim
121 words
The invention is accordance with claim 3 further comprising a pair of spring retaining posts secured to and extending upwardly from said fixture housing rear wall spaced rearwardly of said socket base forward end and positioned on opposite sides of said socket base and said spring means comprises a U-shaped spring having a base portion secured to one of said posts, a first leg abutting the other of said posts, a second leg abutting the socket housing front portion and biased to urge said front portion longitudinally toward said socket base forward end, both said legs rest on the top surface of said socket housing and said spring is further biased to urge said socket housing into said socket base nest.
