Abstract: The invention relates to an elongated luminous element (1) having a plurality of approximately point-shaped light sources (2) disposed along a line and having light diffusion means (3) deflecting at least one part of the light rays (12) sent out by the light sources (2) in a desired direction. The light diffusion means (3) are disposed lateral to the main emitting direction of the light sources. The elongated luminous element (1) is particularly suitable for installation in a light box (13) for advertising or demonstration purposes. The light box has a transparent or partially transparent front side (7) and a reflective back side (8). The elongated luminous element (1) or a plurality thereof is or are applied to at least one of the side areas (11, 14), such that the light rays (12) emitted by the light sources (2) and deflected by the light diffusing means (3) are aimed between or on the back side (8) and/or the front side (7) of the light box (13).
