<p>A light-collimating system for collimating light from a light source has a plurality of elements (2, 2', ...; 12, 12', ...). Each element includes a first wall (3, 3', ...; 13, 13', ...) and a second wall (4, 4', ...; 14, 14', ...). The first wall and the second wall of each element are spaced with respect to each other. The first wall (3; 13) of an element (2; 12) and the second wall (4'; 14') of an adjacent element (2'; 12') form a wedge-shaped structure widening in a direction facing away from the light source. The first and second wall are at a side facing the wedge-shaped structure provided with a specular reflecting surface. Preferably, the space formed between the first and second wall of each element and the supporting member is provided with a specular and/or diffuse reflecting material.</p> |
