LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed April 18, 1919. Serial No. 291,014.

of this invention is the confixture in which the outer surface of an upper opaque reflector sending light rays upward for reflection downward by the ceiling or its equivalent, is illuminated by a lower translucent member. Hitherto in constructions of this type the outer surface of the opaque reflector is illuminated only by reflection from the walls of the room-and is, therefore, sometimes not sufficiently illuminated to prevent it from appearing as a dark object. It is the purpose of this invention to remedy this defect and to accomplish this purpose the trans lucent member is suspended at a distance below the lower edge of the opaque reflector and is preferably extended outwardly beyond such lower edge, whereby rays of light from the source of light not only pass through the translucent member but are in part reflected from the upper surface thereof upwardly and outwardly illuminating the outer surface of the opaque reflector so as to prevent it from appearing as a dark object, while the reflected rays add also to the illumination of the ceiling and the upper portions of the walls of the room. It is contemplated that the proportions of the upper reflector and the lower plate are such that the illuminated sides of the reflector shall not be concealed or hidden by the plate, that is that the plate shall not be of such size and shape as to surround the reflector. The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated and in which- Figure 1 is a view in vertical section of a lighting fixture which embodies the invention, the lamp and its support being shown in elevation.

Fig. 2 is a top view of the fixture shown in Fig. 3 is a view similar to Fig. 1 but showthe translucent member 1) ing a dished, translucent member in place of the flat plate shown in Fig. 1.

The opaque reflector a, made of any suitable material and supported in any convenient manner, is open both at the top and at the bottom, at least so far as the passage 0 light rays is concerned, and has generally a lower contracted portion and an upwardly flaring rim, the curvature of the sides being preferably of the type shown, the outer curve being concave in vertical elevation. The shape may be varied to suit the conditions of use and the requirement of artistic effect. Below the opaque reflector a is supported a translucent member I) which preferably has adiameter somewhat greater than the lower end of the opaque reflector, extending outwardly beyond the edge thereof. This translucent member may be supported in any convenient manner. As shown in the drawing it is supported by a spindle 0 carried by a narrow bridge piece d which, in turn, may be supported by the opaque reflector.

In Fig. 1 of the drawing, the translucent member I; is flat, but obviously it might concaved upwardly or dished, as shown at b in Fig. 3.

As indicated by the broken lines in Fig. 1 some of the rays of light from the source, indicated at e, strike the upper surface of and are thence reflected upwardly and outwardly so that the outer surface of the opaque reflector a is illuminated sufficiently to prevent it from appearing wholly dark except as it may be faintly illuminated by reflection from the walls of the room; the outer as well as the inner surfaces of the reflector may be covered with a reflecting coating of paint or other material or may be composed of material in itself reflective of light to increase the reflective capacity of the outer surface b am screen the effectiveness of the outer surface of the reflector.

I claim as my invention:

1. A lighting fixture comprising an upwardly flaring outwardly concaved opaque reflector open at top and bottom to rays of light, and a translucent member spaced apart from the lower edge of the reflector and extending beyond the lower edge but Within the diameter of the upper opening of the reflector, the translucent member being adapted to reflect a portion of the light striking it to the exterior of the reflector.

2. A lighting fixture comprising a light source, a fixture support, an upwardly flaring outwardly concaved reflector open at top and bottom to rays of light and reflective of light On both surfaces, and a translucent member spaced apart from the lower edge of the reflector but Within the diameter of the upper opening of the reflector, such member being adapted to reflect a portion of the light striking it to the exterior of the reflector.
