ABSTRACT:
A structure for illuminating vertical displays such as pictures or the like includes a rectangular window in the ceiling whose front and rear edges are spaced from the display area so that lines extending between such front and rear edges, and the top and bottom edges of the display area, are approximately between 15.degree. and 45.degree. to the vertical. A series of spaced inclined slats registering with the window have specular front faces and light absorbing rear faces and are inclined, related and dimensioned to direct and confine the ambient exterior light traversing the window to the display area. In one form the slats lie in forwardly downwardly converging planes and have top edges terminating in rearwardly directed flanges lying in a horizontal or inclined plane and a light modulating grid plate may be provided having alternate laterally extending opaque and transparent stripes overly the flanges and the plate is transversely adjustable.
