Abstract

La présente invention se rapporte à un dispositif (1) d'éclairage qui comprend une source lumineuse (2), une surface (3) de révolution ouverte vers le bas d'axe A, dans laquelle est disposée la source lumineuse (2), il est caractérisé en ce que la surface (3) est réfléchissante et sensiblement non-diffusante et de forme concave, que la surface (3) est découpé selon une forme constituée de droites (4) parallèles faisant un angle β avec l'axe A supérieur à 90° et que la source lumineuse (2) est disposée au plus près de la focale de la surface (3) de révolution. La surface renvoit donc les ondes lumineuses qu'elle reçoit uniquement dans une seule direction.The present invention relates to a lighting device (1) which comprises a light source (2), a surface (3) of downwardly open revolution of axis A, in which the light source (2) is arranged, it is characterized in that the surface (3) is reflective and substantially non-diffusing and of concave shape, that the surface (3) is cut in a form consisting of straight lines (4) parallel forming an angle β with the axis A greater than 90 ° and that the light source (2) is disposed closer to the focal length of the surface (3) of revolution. The surface therefore returns the light waves it receives only in one direction.
