Abstract
Abstract An industrial luminaire comprising a central housing formed of two identical parts, a capacitor cover pivotally coupled to one side of the housing having a capacitor therein, a ballast and ballast cover on the other side of the housing, a lamp socket coupled to the bottom of the housing, and a top cover pivotally coupled to the top of the housing. Separation of the capacitor and the ballast from the heat generating lamp provides longer life and higher efficiency for these components. The pivotal coupling of the top cover and the capacitor cover provide for easy access during maintenance. The top cover is coupled to a fixed overhead support over the center of gravity of the entire structure providing a balanced, reduced stress connection.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
134 words
A luminaire assembly comprising: a central housing having a lamp socket extending downwardly therefrom; a capacitor; first means for mounting said capacitor on one side of said housing and externally thereof; a ballast; second means for mounting said ballast on a side of said housing opposite said capacitor with a major portion of said ballast being outside of said housing; a top cover; means for coupling said top cover to the top of said housing; and means for suspending said luminaire assembly from a fixed support, said means for suspending being located on said top cover laterally displaced towards said ballast and engaging the fixed support substantially above the center of gravity of said luminaire assembly, said means for suspending being the sole load bearing element interconnecting said luminaire assembly and said fixed support.
Claim 2
Dependent Claim
134 words
A luminaire assembly comprising: a central housing having a lamp socket extending downwardly therefrom; a capacitor; first means for mounting said capacitor on one side of said housing and externally thereof; a ballast; second means for mounting said ballast on a side of said housing opposite said capacitor with a major portion of said ballast being outside of said housing; a top cover; means for coupling said top cover to the top of said housing; and means for suspending said luminaire assembly from a fixed support, said means for suspending being located on said top cover laterally displaced towards said ballast and engaging the fixed support substantially above the center of gravity of said luminaire assembly, said means for suspending being the sole load bearing element interconnecting said luminaire assembly and said fixed support.
