Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A new and improved industrial luminaire system comprising: an optical assembly, having a socket housing, a lamp socket, a lamp, a reflector mounted therein, an electric assembly for physically supporting the optical assembly and providing an electrical power source to the lamp socket and the lamp of of said optical assembly, mechanical means for both fastening th e optical assembly to and disengaging it from the electrical assembly, electrical disconnect means for supplying electrical power from the electrical power source to the lamp socket of the optical assembly, said mechanical means including a latching mechanism both for quickly fastening the optical system to the electrical assembly and quickly disengaging it from the electrical power source, and said lamp socket housing being made of die cast aluminum and being provided with radiating fins for maximum dissipation of lamp heat.
Claim 2
Dependent Claim
138 words
A new and improved industrial luminaire system comprising: an optical assembly, having a socket housing, a lamp socket, a lamp, a reflector mounted therein, an electric assembly for physically supporting the optical assembly and providing an electrical power source to the lamp socket and the lamp of of said optical assembly, mechanical means for both fastening th e optical assembly to and disengaging it from the electrical assembly, electrical disconnect means for supplying electrical power from the electrical power source to the lamp socket of the optical assembly, said mechanical means including a latching mechanism both for quickly fastening the optical system to the electrical assembly and quickly disengaging it from the electrical power source, and said lamp socket housing being made of die cast aluminum and being provided with radiating fins for maximum dissipation of lamp heat.
Claim 3
Dependent Claim
52 words
A new and improved industrial luminaire as defined in claim 1 wherein the optical assembly is totally sealed to exclude insects, dust, and dirt, and has a fiber glass filter positioned between the socket housing and the lamp socket to insure a clean exchange of air during lamp heating and cooling cycles.
Claim 4
Dependent Claim
54 words
A new and improved industrial luminaire as defined in claim 2 wherein the optical assembly includes a prismatic reflector and an internally attached aluminum reflector providing support for the prismatic reflector, heat shielding for the socket and a reflective surface for reflecting any upward light to enhance the lighting output of the optical assembly.
Claim 5
Dependent Claim
106 words
A new and improved industrial luminaire as defined in claim 3 wherein longitudinal rods each of which has one end connected to the socket housing at the top and the other end threaded and extending through holes in a metal support ring at the bottom engaging a lower flange of the prismatic reflector are securely fastened to the metal support ring by nuts engaging their threaded ends the tightening of which not only provides additional support for the prismatic reflector but places the glass of the prismatic reflector in compression strengthening the glass so that the reflector is much less likely to break if accidentally struck.
Claim 6
Dependent Claim
31 words
A new and improved industrial luminaire as defined in claim 4 wherein the optical assembly includes a bottom closure for providing access to the interior of the optical assembly for relamping.
Claim 7
Dependent Claim
34 words
A new and improved industrial luminaire as defined in claim 5 wherein the bottom closure is pivotally mounted on a hinge and normally held in a closed position by a pair of spring latches.
Claim 8
Dependent Claim
29 words
A new and improved industrial luminaire system as defined in claim 1, wherein interchangeable optical assemblies provide various light distribution patterns without a need to change said electrical assembly.
