1 Claim.
The present invention relates to inewand improved fixtures and reectors primarily adapte p for .use with fluorescent tube lamps.
An important object of the invention resides in the provision of a xture and reflector for y uorescent tube lamps that may be used as a single unit o-r in multiple units and adapted to be used with or Without a glass panelin fro-nt of the reflector and lamp;
The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in con- Thelreflector 115' is .preferably-'formed of high- Ily `polished :aluminum ,orsimilar material, .the sideportions |l6 ofwhich are shaped .tot within the oiset portion I4 of the fixture I6 for attaching the reflector thereto `by means of bolts or the like I'I. The reflector i5 is convexed longitudinally as indicated at i3 to form a multiplicity v of individual corrugations which cooperate with the iluorescent tube lamps I to reflect the beams of light into every section of the room, display case or the like with which the iixture is used. n
The tubes. I9 extend longitudinally of the fixture and are disposed in front of the apex of nection with the accompanying drawings which form a part of the application.
In the drawings: i
Figure 1 is a side elevational View of a reflector and fixture embodying the features of the present invention.
Figure 2 is a vertical sectional view taken substantially on` line 2 2 `of Figure 1.
Figure 3 is a perspective lview of the reiiectorl element removed `from thel fixture.
Figure 4 is a vertical sectional View of a re` p ector and xture and illustrating theuse of a crvedvglass enclosure.
Figure 5 `is a vertical sectional View of a reflector and fixture of a single unit.
Figure 6 is a vertical sectional View of a reiiector and xture illustrating a double unit.
Figure 'l is a vertical sectional View illustrating the reflector in use in the corner of a display case or the like.
Referring to the drawings for a more detailed description thereof, a xture comprising a sub-v stantially rectangular-shaped frame is indicated generally by the reference numeral It, the same being formed of any desired light weight material and adapted to be attached to a ceiling or the like by any desired means. As shown in Figure 2 of the drawings, the fixture Ifl is substantially hollow being formed with angularshaped side and end portions II and I2, respectively. The bottom I3 of the xture has a relatively at surface with theopposed sides-thereof having an offset portion It to which is attached the reector generally designated by the niu'neral I5.
each corrugation as more clearly shown in Figure 2` of thedrawings, said tubes being supported in brackets 2i!` depending from the fixture I0. An important feature of the invention resides in assembling the fixture whereby the inverted V-shaped portions l of the reector rise to a point directly above the fluorescent tube Whereby full benet of light from the tube is obtained.
If desired, a relatively at sheet of transparent glass 2I may be supported infront of the tubes and reflectors, the same being supported from the xture by means of adjustable brackets 22. As is to be understood, the brackets 22 can be lengthened or shortened. through their intermediate portions 23 for bringing the glass panel 2| closer to or further away from the tubes I9.
In Figure 4 of the drawings, there is illustrated a fixture and reflector identical with that disclosed inV Figures l, 2 and 3. It will be noted, however, that there is employed a curved transl parent glass dome 24 in place of the iiat glass panel 2| whereby the reflector I5 and tubes I9 are completely enclosed. The curved dome 24 is associated with the fixture Iii and held thereto by means of a retaining ring 25, said ring being removably attached to the fixture by a threaded screwlor the like 25 which construction permits removal and replacement ofthe dome 24.
In Figure 5.0i the drawings, there is illustrated a single unit embodying a miniature xture 21 having attached thereto a reflector 28 which reflector includes a single corrugation 29 beneath which is positioned a fluorescent tube 38. The reector 28 and tube 3B are attached to the fixture 2l, in the manner previously described. In the single unit the use of a glass panel or dome,
t as in the previously described forms, has been dispensed with.
A further modified form of the invention is disclosed in Figure 6 of the drawings, which modification represents a double unit in that a pair of tubes 3l extend from the fixture 32 being placed at the apex of each of the corrugations 33. In this form of the invention, it will be noted that the reflector 34 is formed with a slight curvature to provide vthe longitudinal corrugations 33, the curvature assisting in providing improved illumination when using this type of unit.
In Figure '7 of the drawings, a reflector of the type hereinabove described is disclosed in use within the corner of a display case 35 and it will Lbe noted that the uorescent tube 36 is positioned of .substantial equivalents for the devices described are intended to be comprehended within the spirit of the present invention and that the invention is capable of extended application and is notconfned to the exact showing of the drawings nor to the precise Construction described Y and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claim.
What is claimed is:
A fixture for fluorescent tubes, comprising a substantially rectangular shaped frame with its outer face having rectangular shaped recesses extending across the same adjacent the side edges,
a reflector having convex corrugations engaging the frame and provided with flat faces beyond the corrugations engaging the frame, the side edges of the flat faces having rectangular inwardly extending side edges entering said rectangular recesses, and bolts passing through the said rectangular side edges and the bottom of said rectangular recesses.
