SOLAR PANEL ENABLING THE DISPLAY OF AN IMAGE

摘要

The invention relates to an optical assembly (1) for displaying an image on the surface of a solar panel, comprising a solar panel, the surface of which is at least partially covered by a lens array, with an image being disposed between the solar panel and the lens array in the form of substantially equidistant parallel strips with a predetermined spacing. Said optical assembly (1) is such that: the lens array has an inner planar surface and an outer surface formed by the outer surface of a series of identical adjoining cylindrical transparent elements, the generatrix of which is parallel to said strips; the outer side of the base of each cylindrical element has an asymmetrical profile; the width of each transparent element is equal to the spacing of the strips; and the strips are placed such that, for a first angular range (a) of given incidences under which the optical assembly is to be observed, radiation can reach an area in which a strip is placed, and, for a second angular range (b) of lower given incidences, radiation can reach the active surface of the solar panel within an area having at least one portion that is not masked by the strips. The invention also relates to a method for correctly aligning the lens array with the strips.
