My fixture therefor, handles the light much more efficiently than any othor lighting fixture known to main that it effectively hrings practically all the" li ht to the workin plane first instead of directing or permitt ng a large portion to pass to tho (oiling to be reflevted thence to the working plane. Ceilings, unless spo vially mmstructed, are poor reflectors and,

moreover, the intensity of light decreases rapidly with increasing distance from the source.

I am aware that modifications in details of construction may be made without sacrificing the principle of my invention and I, therefore,'do not desire that it be limited otherwise than by the appended claims.

Having fully described my invention, what I claim as ne and desire to secure by Letters-Patent of the United States is:

1. In alighting fixture, the combination with a reflecting member having a horizontally disposed flat lower reflecting surface, of a translucent light diffusing bowl open ing toward the central portion of the reflecting surface and positioned a short distance below said surface to provide free space for the passage of light between the reflecting surface and the upper edge of the bowl, the bowl opening being of smaller area than the reflecting surface, bowl suspending means attached to the upper part of the bowl, and a source of light within the bowl and near the reflecting surface, the relative position of the bowl, source of light and reflecting surface being such that all of the rays of light not passing directly from the source to the inner surface of the bowl will strike opening toward the central portion of the flat reflecting surface, the area of the bowl opening being less than that of the said reflecting surface, a lamp in the lamp receptacle and extending into the bowl, means for suspending the bowl so that light passing downwardly through it will be unobstructed, the bowl, lamp and reflecting surface being positioned with relation to each other to cause substantially all the rays of light from the lamp to be directed downwardly and distributed in a diffused condition over the entire surface of a horizontal plane beneath the fixture and of greater area than the reflecting member.
