Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
A lighting apparatus having a substantially tubular casing structure of transparent or translucent flexible material, a reinforcing means inside said tubular casing structure to allow said structure to assume a variety of stable curved line arrangements, a plurality of supporting means arranged spaced apart inside said tubular casing structure and said reinforcing means in engagement therewith, a plurality of lamps each arranged between two of said supporting means, electrical connection means between said lamps arranged inside said supporting means to electrically connect one of said lamps to the following lamp, and conductor means for supplying electric power to said plurality of lamps.
Claim 2
Dependent Claim
102 words
A lighting apparatus having a substantially tubular casing structure of transparent or translucent flexible material, a reinforcing means inside said tubular casing structure to allow said structure to assume a variety of stable curved line arrangements, a plurality of supporting means arranged spaced apart inside said tubular casing structure and said reinforcing means in engagement therewith, a plurality of lamps each arranged between two of said supporting means, electrical connection means between said lamps arranged inside said supporting means to electrically connect one of said lamps to the following lamp, and conductor means for supplying electric power to said plurality of lamps.
Claim 3
Dependent Claim
44 words
An apparatus as claimed in claim 1, wherein said reinforcing means comprise at least one spiral member wound inside said tubular casing structure in engagement therewith, said spiral member including an electric wire forming said conductor means for supplying electric power to said lamps.
Claim 4
Dependent Claim
38 words
An apparatus as claimed in claim 1, wherein said lamps arranged between said supporting means have an elongated tubular shape and two ends having a rounded portion at least partially shaped as a part of a spherical surface.
Claim 5
Dependent Claim
54 words
An apparatus as claimed in claim 3, wherein said supporting means comprise a substantially spherical hollow body having two diametrical opposite openings forming seats for said rounded portions of the ends of said tubular lamps, said body having a diameter substantially equal to the diameter of a wind of said spiral of wire material.
Claim 6
Dependent Claim
56 words
An apparatus according to claim 4, wherein said tubular lamps include end caps having counter-caps mounted by pressure on said caps, said counter-caps having an external configuration of substantially hemispherical form for cooperating with said seats of said spherical hollow bodies, and allowing angular displacement of said tubular lamps with respect to said spherical hollow bodies.
