Abstract

The invention relates to a lighting device (11) which resolves the problem of uniformly distributing light on a surface, in particular on a rectangular surface, from a so-called area light source, such as a light emitting diode (LED) or an off-centre organic light emitting diode (OLED). Said lighting device includes a light source (20) connected to a specific structuring optical unit (30) for lighting the predetermined surface. Said specific structuring optical unit (30) comprises an ophthalmic lens (31) for structuring the lighting of the predetermined surface (10), said lens comprising an input surface (33) for the light rays emitted by the light source (20) and an emitting surface (36) for the light rays that pass through the ophthalmic lens (31). The input surface (33) of the ophthalmic lens is configured such as to place the lighting area of the light source (20) vertically adjacent to the predetermined surface to be lighted, the emitting surface (36) of the ophthalmic lens being arranged such as to ensure the uniformity of the light across the entire predetermined surface.
