Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
153 words
A luminaire comprising, in combination, a functional lighting unit comprising an optical system including illuminating means, electrical means for operating said illuminating means, and support means holding said optical system and said electrical operating means in unitary assembly, said support means having a first mounting portion, housing means of preselected shape substantially enclosing said functional lighting unit and having a second mounting portion arranged adjacent said first mounting portion, slipfitter means arranged adjacent said mounting portion of said housing means, and bracket means secured to said support means and said housing means at said mounting portions thereof and to said slipfitter means for holding said functional lighting unit and said housing means in assembly with said slipfitter means, said bracket means being selectively positionable relative to said support means for accommodating housing means of different preselected shape, whereby said first-mentioned housing means is interchangeable with different housing means on said functional lighting unit.
Claim 2
Dependent Claim
153 words
A luminaire comprising, in combination, a functional lighting unit comprising an optical system including illuminating means, electrical means for operating said illuminating means, and support means holding said optical system and said electrical operating means in unitary assembly, said support means having a first mounting portion, housing means of preselected shape substantially enclosing said functional lighting unit and having a second mounting portion arranged adjacent said first mounting portion, slipfitter means arranged adjacent said mounting portion of said housing means, and bracket means secured to said support means and said housing means at said mounting portions thereof and to said slipfitter means for holding said functional lighting unit and said housing means in assembly with said slipfitter means, said bracket means being selectively positionable relative to said support means for accommodating housing means of different preselected shape, whereby said first-mentioned housing means is interchangeable with different housing means on said functional lighting unit.
Claim 3
Dependent Claim
37 words
A luminaire as defined in claim 1, said bracket means being arranged within said housing means and said second mounting portion of said housing means interposed in the assembly between said bracket means and said slipfitter means.
Claim 4
Dependent Claim
66 words
A luminaire as defined in claim 2, said functional lighting unit extending outwardly from said slipfitter means along a first axis, said slipfitter means being generally tubular and extending along a second axis transverse said first axis, whereby said slipfitter means may be mounted on a vertical pole and is adapted to have a plurality of functional lighting units and associated housing means extending outwardly therefrom.
Claim 5
Dependent Claim
55 words
A luminaire as defined in claim 3, said support mean comprising a yoke member arranged about and secured to said optical system, and having spaced arms projecting rearwardly toward said slipfitter means, said bracket mean comprising a U-shaped member having spaced arms detachably secured in overlapping relation to the corresponding arms of said yoke member.
Claim 6
Dependent Claim
81 words
A luminaire as defined in claim 4, said U-shaped bracket member having a web portion in engagement with said mounting portion of said housing means, said latter mounting portion having a shape corresponding to said preselected housing shape, said web portion having a first surface portion engaging said housing mounting portion and having a shape complementary thereto, said web portion having a second surface portion having a different shape complementary to the mounting portion of housing means of different preselected shape.
Claim 7
Dependent Claim
45 words
A luminaire as defined in claim 4, said housing mean comprising a canopy covering said functional lighting unit and a sidewall surrounding said unit, and spacer means connected to and arranged between said canopy and said yoke membeR for holding the same in spaced relation.
Claim 8
Dependent Claim
78 words
A luminaire as defined in claim 4, said housing mean comprising a canopy covering said functional lighting unit and a sidewall surrounding said unit, said sidewall having upper and lower portions extending therearound, said upper portion embracing the periphery of said canopy, said housing means further comprising a light-transmitting annular member surrounding said optical system and occupying the space between the same and said sidewall, said annular member being detachably secured to the lower portion of said sidewall.
Claim 9
Dependent Claim
