' LIGHT FIXTURE Filed Jul 1. 193a .ao/ l a/ i/ /1 Patented Oct. 1, 1940 UNITED STATES PATENT OFFICE 2 Claims.

The principal object of this invention is to provide an indirect light fixture that gives the optical illusion of possessing glass or translucent light deflecting vanes or louvers.

5 More specifically, the object of my invention is to provide a light fixture of the indirect light type that has metal light bafiling members that are so shaped, constructed and arranged that the same are substantially undetectable from trans- ,0 lucent light diffusing elements.

A still further object of my invention is to provide a light fixture of the indirect lighting type that is substantially non-breakable, easily cleaned and highly efiicient.

5 A still further object of this invention is to provide an indirect light fixture that is highly attractive, economical in manufacture and durable in use.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth,

; pointed out in my claims and illustrated in the accompanying drawing, in which:

Fig. l is a front sectional view of my light ready for use.

Fig. 2 is a top plan view of my light fixture and more fully illustrates its construction.

Referring to the drawing, I have used the numeral I0 to designate the flat base of my device. The numeral I I designates two spaced apart half circle bracket rings operatively rigidly secured to the base Ill and extending forwardly from the base It as shown in Fig. 2. The numeral I 2 designates a longitudinal bar on the front dead center face of the-base board Hi having its forward surface some distance forward of the plane of the base board II). This member I2 is 0 designed to hold and support a plurality of incandescent light sockets IS in spaced relationship along its center front. These sockets I3 may be of the usual type, each having the usual electric lead wires I4 and I5. These wires I4 and I5 are each designed to be in communication with a source of electric energy when the fixture is in lighted use. In practice the plurality of sockets I3 may be wired in series or may be wired in a 0 single electric circuit. The numeral I5 designates an electric light bulb in each of the sockets I3. For difierent color lighting effects, these lamps I6 may be of different colors. When the lamps I8 are in place, the fixtures are so designed 5 that they will form a longitudinal line within the center plane of the ring brackets II as shown in Fig. 2. The parts of the fixture thus far described provide the framework of my device. The principal feature of my lamp fixture, however, is the elongated vanes or louvers arranged longi tudinally on the framework of the fixture. These louvers are of metal or other suitable material incapable of light rays passing through them. All of the louvers of my device are S-shaped in cross section as shown in Fig. 2. I have used the m numeral I! to designate the spaced part louvers secured to the circular brackets II. I have used the numerals I8 and I9 to designate the two louvers on the center front of the two bracket rings I I. These vanes or louvers are secured at their rear marginal edges by any suitable means such as by spot-welding, soldering or like to the bracket rings II. All of these louvers thus far described extend in a curved line first forwardly and outwardly and then forwardly and inwardly go as shown in Fig. 2. The louvers H and the rear edge portions of the louvers I8 and I9 are so arranged and spacedapart from each other that the forward marginal edge portion of one louver always over-laps the rear marginal edge portion of the louver just ahead of it. By this arrangement, no straight radial line can be drawn from any of the lamps I6 forwardly and outwardly without striking one of the louvers. As the vanes II, I8 and I9 are incapable of passing light through them, an observer cannot directly see the lamps I6 from a point in front of the fixture. The louvers I8 and I9 have their outer marginal edges joined as shown in Fig. 2 and the louvers I! extend from each side of these members I8 and I9 in spaced relationship toward the base board Ill. The progression of these louvers, due to the circular brackets II, proceed in a like circular path arrangement. The louvers II, I8, and I9 are duplicates and may be painted or plated in any desired color. To achieve combinations of color I, however, recommend that these louvers I'I, I8 and I9, and the other reflecting louvers of the device, be either of bright metal or else be painted or plated in a white or cream a color and used with differently colored lamps I6 to obtain the desired color efiect. The reflecting board directly back of the lamp I6 may be made from two louvers or vanes which I have designated by the numerals 20 and 2|. These louvers 50 20 and H are also S-shaped in cross section having the same contours as the louvers or vanes I! and these S-shaped louvers, extend outwardly from the center portion of the lamp, are then curved rearwardly and thence outwardly. At the I outer side of each of the louvers 20 and 2! is a second louver 22 and 23 also S-shaped in cross section and extending outwardly and curving rearwardly and thence curving outwardly and forwardly as shown in Fig. 2 of the drawing. A filler vane 24 may extend between the outer edge of the vanes 22 and the back board Ill. A similar filler vane 25 may extend between the outer edge of the vane 23 and the back board [9.

From the foregoing it will readily be seen that the vanes l1, l8, I9, 22, 2|, 22 and 23 are all substantial duplicates and S-shaped in cross section. The vanes 20, 2|, 22, and 23 provide a reflecting back board of the lamps l6. Due to this resultant reflecting board being of wave construction in cross section, light will be reflected. at a variety of angles to the forward vanes H, i8 and 19. Certain of the light rays from the lamps I6 will directly strike these forward vanes I1, [8, and I9 and be deflected to an observer in front of the" fixture. However, a great number of light rays will strike some of the forwardly arranged vanes and will be deflected on the other of the forwardly arranged vanes I l, l8, and #9. It is this reflection of light from some of these vanes to other of the forward vanes that gives the optical illusion that all of the vanes are made of translucent material, when as a matter of fact, they are of metal or like material and light cannot pass through them. The result is a highly desirable efficient lighting fixture of the indirect light type. All observable light is indirect and by the light being directed indirectly to the outer side of each of the forwardly arranged vanes l8, and I9, there will be no dark spots in the entire fixture, but on the other hand the fixture will be a glow of light radiating from its entire surface. By the use of these louvers, S-shaped in cross section and in arrangement as shown in Fig. 2, it will be noted that either direct or reflected light will be at'all points on both sides of all of the louvers l1, l8 and l9.

Although I have described my fixture as one being vertically arranged on a wall or like, it is obvious that it can be placed transversely on the wall or it may be placed on a ceiling or the like.

Some changes may be made in the construction and arrangement of my improved light fixture without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included withintheir scope.

I claim:

1. In a device of the class described, a base member, a lamp on said base member, a plurality V of straight longitudinally extended spaced apart opaque vanes arranged forward of said lamp; said vanes being S-shaped and so designed and arranged that each vane reflects the rays from said lamp on to the outward surface of the next succeeding vane and no light rays can pass in a direct line between any two vanes from said lamp, and a plurality of consecutively extending S- shaped members on said base for reflecting the rays from said lamp on to said S-shaped vanes.

2. In a device of the class described, an elongated base member, a reflecting surface forward of said base member consisting of a plurality of S-shaped elongated elements, a lamp on said base member extending forwardly of said reflecting surface, spaced apart bracket rings secured to said base member, and a plurality of spaced apart straight opaque vanes S-shaped in cross section secured to said bracket rings and arranged about said lamp; said vanes so designed and arranged as to directly reflect light rays from said lamp on to the outer sides of each other and no light rays can pass in a direct line between any two vanes from said lamp.
