Claim 6
Dependent Claim
70 words
A combined elongated light fixture and shade structure as claimed in claim 1 wherein the means located in said first end plate, adapted for the lengthwise insertion therethrough of a fluorescent tube into an initial position inside the said first housing, further comprises, an inlet opening for a tube located outside said first socket, said inlet opening being dimensioned to receive a fluorescent tube inserted lengthwise into said first housing.
Claim 7
Dependent Claim
103 words
A combined elongated light fixture and shade structure, as claimed in claim 4, wherein each said cross plate conforms to the inner cross-section of said first housing, and wherein said elongated opening in each said cross plate further comprises a first portion, surrounding said final position of the tube, a second portion, surrounding said initial position of the tube, and a connecting passage connecting said first and second portions, wherein the diameters of said first and second portions and the width of said connecting passage are each greater than the diameter of the largest tube adapted to be mounted in the light fixture.
Claim 8
Dependent Claim
59 words
A combined elongated light fixture and shade structure, as claimed in claim 6, wherein said first and second portions of said elongated opening are each bounded by a semi-circle of diameter greater than that of the largest tube adapted to be mounted in the light fixture, and said connecting passage is bounded by straight lines tangentially connecting said semi-circles.
Claim 9
Dependent Claim
48 words
A combined elongated light fixture and shade structure, as claimed in claim 6, wherein each said cross plate has an aperture, in its edge facing away from said open light-emitting side, adapted to receive and guide electric wiring between said first and second sockets and said transformer unit.
Claim 10
Dependent Claim
70 words
A combined elongated light fixture and shade structure as claimed in claim 3, wherein said second housing comprises extensions of said side plates and top plate past said second end plate, and a transverse outer plate connected to said extensions, and wherein said second housing has an opening, on the side corresponding to the light emission opening of the first housing, said opening being fitted with a detachable closing plate.
Claim 11
Dependent Claim
37 words
A combined elongated light fixture and shade structure, as claimed in claim 9, wherein the distance between said transverse outer plate and said second end plate is the same as the distance between adjacent said cross plates.
Claim 12
Dependent Claim
40 words
A combined elongated light fixture and shade structure, as claimed in claim 5, wherein said inlet opening has a cover, detachable from the outside, which is adapted to be connected to said second end plate, to cover said inlet opening.
Claim 13
Dependent Claim
51 words
A combined elongated light fixture and shade structure, as claimed in claim 5, wherein the center of said second socket and the center of said inlet opening are located on an imaginary straight line on said second end plate, which makes an angle greater than 45° with said imaginary median plane.
Claim 14
Dependent Claim
29 words
