Application February 9, 1945, S`eria1Nvo". 57.6,914

My invention relatesto an improvement in lighting equipment. One purpose is to providean ornamental lighting member. y

Another' purpose is to provide alightinig* mem-- ber which inherently thro-ws a li-gfht from ari interior light source in a predetermined direction.

Another purpose is to provide a tubular light element which throws light downwardly toward and about the base of a tube or toward a predetermined area to be illuminated.

Another purpose is to provide a light which may advantageously be used in display devices, showcases and the like and which is ornamental and also constitutes an elcient lighting medium.

Another purpose is to provide a lighting element which includes means for preventing direct impingement of light rays upon the eyes of the observer.

Another purpose is to provide a lighting feature which may function as a structural member or support.

Other objects will appear from time to time throughout the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein:

Figure 1 is a side elevation with parts broken away and parts in section;

Figure 2 is an axial section on an enlarged scale; and

Figure 3 is a section along theline 3 3 of Figure 2.

Like parts are indicated by like characters throughout the specification and drawings.

Referring to the drawings, I indicates a tubular light which may be of any suitable type and preferably has afitting 2 at each end with any suitable electric contact orcontacts 3. The lighting tube or bulb itself does not form part of my invention. Surrounding it, I illustrate a tubular member generally indicated as 4 which may be open at each end as at 5 and which may be formed of any suitable transparent ortranslucent material 6.

Arranged along the tube are a plurality of generally conic members 'I which may be opaque or less translucent than the interveningportions 6 o1 may be differentiated in color from themembers 6. They may, for example, be vof opaque material with a reflective lower face. I0 is any suitable bracket for the bottom of the tube I. It may be provided with electric contacts not herein shown, to receive the projecting contact orcontacts 3 from the base of the tube. The

3 claims.- (cl. arca-108) serve as a structural member.

`2. v member I0 may be supported as by the-flange H- on any suitable base support door or wall I2'.

I 3 indicates any suitable securingmember such as la' bolt or screw. The upper end of the tube 'I extends beneath an upper bracket elem-ent l5 shown as mounted by a harige I6 upon any suitable Wall or support I1 to which it may be secured by a securing member I8. The member I5 will also be understood to have any suitable receiving contact or socket for the projecting contact orcontacts 3 of the upper end of the tube I.

With the parts in the position of Figures l or 2, an interior source of light is surrounded by the outer tube. The members I are so spaced and proportioned that no light directly escapes laterally toward the observer, if the members I are of opaque material. However, light can freely shine downwardly and outwardly through the intervening transparent ortranslucent portions 6 and Will be effective to illuminate articles positioned about the exterior of the tube 4 or located within the cone of illumination provided by the tube 4.

I may form the tube 4 of suicient strength to For example, taking Figure 1 as diagrammatic, the member I0 may receive a base on which the lower end of the tube 4 rests. The member I5 may then rest on the upper end of the tube 4 and the tube 4 may be employed to support any suitable upward structure diagrammatically represented by I5, I6 and I'I. For example, in a display structure which might be mounted on the top of a counter or on a oor or suitable support, one or more of the tubes 4 may be used as supports for an upper element.

One advantageous use of my invention is in connection with tubes in which theparts 6 are transparent and the parts 'I are opaque. They therefore constitute fixed shutters for preventing the lateral radiation of light from the enclosed light source I. It may be advantageous to render the lower faces of themembers 1 reective.

Another application of my invention is to employ contrasting colors. For example, if themember 6 is transparent, the members 'I may be transparent or translucent or opaque, with thememfbers 6 and 1 of dilerent coloring.

My invention can be employed with a variety of materials but I und it preferable to use plastics.

It will be realized that whereas I have shown and described an operative device, still many changes might be made in size, shape, number and disposition of parts without departing materially nate adjacent the inner face of said tubular member.

2. For use with a tubular light source, a unitary tubular shade of transparent material, said shade having embedded therein a plurality of conic opaque louvre members, the larger ends of said conic members being located adjacent to the outer l surface of said tubular member, said conic members extending upwardly and inwardly to terminate adjacent the inner face of said tubular member, said shade being open at each end, and of substantially uniform diameter from end to end.

3. An elongated, hollow, cylindrical housing adapted to receive and completely mask a tu- 4 bular light source, said housing comprising alternate conical bands of translucent and opaque ma terial, both types of bands extending from the inside to the outside of the housing, said bands increasing in diameter downwardly, the upper boundary of each opaque band lying in the plane of the lower boundary of the opaque band immediately above it, the inner and outer peripheries of the housing being cylindrical and smooth.
