LED luminous element for illuminating a light box having homogeneous light distribution
First Claim
1. An elongate luminaire element (1) with a plurality of approximately punctiform light sources (2) comprising LEDs arranged along a longitudinal direction, with a lens (6) which covers a plurality of or all of the light sources (2), wherein an exit angle of the light sources is focused by the lens, and one or more planar light diffusion means having a form of a wall (3), which extend in a longitudinal axis of the luminaire element (1) on one side or on both sides and parallel to an axis of symmetry of a light exit cone of the light sources (2).

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).
