Abstract

The lighting module, comprising a preferably elliptical reflector (1) with a concave wall (2), a convergent lens, and a reflective surface or bender (7), has the latter joined by its forward edge to the lens and made with a cut-off rear edge. The concave surface of (1) faces upwards and is situated below the level of (7), with a light source (5) shining downwards into the concavity of (1). The lighting module, comprising a preferably elliptical reflector (1) with a concave wall (2), a convergent lens, and a reflective surface or bender (7), has the latter joined by its forward edge to the lens and made with a cut-off rear edge. The concave surface of the reflector faces upwards and is situated, at least for the main part, below the level of the bender, with a light source (5) shining essentially downwards into the concavity of the reflector. The lens consists of an upper section (Lh) located above the bender, and a lower section (Lb) which has a block (6) extending rearwards from it with its upper horizontal surface acting as the bender for light rays entering the block.
