ABSTRACT:
A lampshade made in accordance with this invention is characterized in that it consists solely of a plurality of comparatively thin sheets of a same shape corresponding to a front vertical cross-sectional view of the lampshade or a vertically cut out half of said view. Each sheets has strips which are aligned in parallel with each other, and each strip has a base portion located adjacently to an outer contour of the sheet and a free end located oppositely to the base portion. When the plurality of sheets bound together at least at upper ends thereof are framed to the lampshade, they extend radially outwardly with a desired angular distance therebetween and strips thereof bridge over the outer contours of the sheets.
