from the direct rays when the sun has descended so that these rays make an angle with the principal plane of the prism-light greater than forty-five degrees. With the lenses as herein shown the rays from the sun or bright source of light will pass through the plate and be directed into the apartment throughout the entire range of the sun or bright source of light, and hence these rays may be successfully utilized during all the various positions of the bright source of light, provided, of course, the rays strike the window containing the lenses.     I claim—     1. As a new article of manufacture, a window-light or the like, comprising a substantially flat relatively thin body portion of transparent homogeneous material provided on one side with a substantially flat surface and on the other with a series of cone-like projecting lenses systematically arranged so as to produce an increased illuminating effect

and placed so that the lines of their bases intersect each other, thus to cover substantially all of such surface with such cone-like projections.     2. As a new article of manufacture, a window-light or the like, comprising a substantially flat relatively thin body portion of transparent homogeneous material provided on one side with a substantially flat surface and on the other with a series of cone-like projecting lenses systematically arranged so as to produce an increased illuminating effect and placed so that the lines of their bases intersect each other, thus to cover substantially all of such surface with such cone-like projections, the upper side of each of said cones cut away, substantially as shown and described.
