Abstract:
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.
