an optical assembly removably affixable to said top mounting assembly; and an electrical assembly including a lamp socket removably affixable to said optical assembly and mechanically coupled to said top mounting assembly by a quick disconnect wherein said electrical assembly is in electrical communication with said top mounting assembly. ### Claim 2 (depends on 1) A modular luminaire assembly as in claim 1, wherein said electrical assembly comprises: a mounting plate; a ballast; and a capacitor, the lamp socket, ballast and capacitor each affixed to said mounting plate and having electrical connections which terminate in said quick disconnect. ### Claim 3 (depends on 2) A modular luminaire as in claim 2 wherein said electrical assembly further comprises a starter having an electrical connection which terminates in said quick disconnect. ### Claim 4 (depends on 1) A modular luminaire assembly as in claim 1, wherein said top mounting assembly comprises: a cover portion; a terminal block affixed to said cover portion; an access cover plate; and a mounting assembly quick disconnect in electrical contact with said terminal block and affixed to said access cover plate for mechanical coupling to said electrical assembly quick disconnect. ### Claim 5 (depends on 4) A modular luminaire assembly as in claim 4, further comprising retaining means for retaining said optical assembly to said top mounting assembly during replacement or repair of said electrical assembly. ### Claim 6 (depends on 5) A modular luminaire assembly as in claim 5, wherein said retaining means comprises a hinge pin affixed to said optical assembly and a hinge affixed to said top mounting assembly which is adapted to rotatably receive said hinge pin. ### Claim 7 A modular luminaire, comprising: a top mounting assembly; an optical assembly having illumination means for generating light, said optical assembly selected from a plurality of approved optical assemblies and removably affixable to said top mounting assembly; an electrical assembly including a lamp socket in electrical contact with said illumination means, said electrical assembly selected from a plurality of approved electrical assemblies; and energizing means for providing electrical energy to said electrical assembly, said energizing means mechanically coupled to said electrical assembly by quick disconnect, wherein said top mounting assembly, said optical assembly and said electrical assembly form first, second and third unitary modules. ### Claim 8 (depends on 7) A modular luminaire assembly as in claim 7, wherein said electrical assembly comprises: a mounting plate; a ballast; and a capacitor, the lamp socket, ballast and capacitor each affixed to said mounting plate and having electrical connections which terminate in a quick disconnect. ### Claim 9 (depends on 8) A modular luminaire assembly as in claim 8 further comprising a starter having an electrical connection which terminates in said quick disconnect. ### Claim 10 (depends on 8) A modular luminaire assembly as in claim 8, wherein said top mounting assembly comprises: a cover portion; a terminal block affixed to said cover portion; an access cover plate; and a quick disconnect in electrical contact with said terminal block and affixed to said access cover plate for mechanical coupling to said electrical assembly quick disconnect. ### Claim 11 (depends on 7) A modular luminaire assembly as fin claim 7, further comprising retaining means for retaining said optical assembly to said top mounting assembly during replacement or repair of said electrical assembly. ### Claim 12 (depends on 11) A modular luminaire assembly as in claim 11, wherein said retaining means comprises a hinge pin affixed to said optical assembly and a hinge affixed to said top mounting assembly which is adapted to rotatably receive said hinge pin. ### Claim 13 A modular luminaire assembly, comprising: a top mounting assembly; an optical assembly affixable to said top mounting assembly wherein said top mounting assembly is pivotable from a closed operating position to an open repair position; and an electrical assembly removably affixable to said optical assembly and mechanically coupled to said top mounting assembly by quick disconnect. ### Claim 14 (depends on 13) A modular luminaire assembly as in claim 13, further comprising: a hinge pin affixed to said optical assembly; and a hinge affixed to said top mounting assembly and adapted to receive said hinge pin such that said optical assembly may be rotatably opened and supported during repair. ### Claim 15 (depends on 14) A modular luminaire assembly as in claim 14, further comprising locking means for retaining said optical assembly in said closed operating position. ### Claim 16 (depends on 15) A modular luminaire assembly as in claim 15, wherein said locking means comprises: an aperture disposed in said optical assembly; a threaded hole disposed in said top mounting assembly; and a captive screw adapted to be positioned through said aperture and retained in said threaded hole.
