A light projection apparatus (10) for projecting an illuminated line onto a surface which comprises a light source (11) for emitting a light beam and a light beam deflection lens (13) which is adapted to receive the emitted light beam and project a work light beam which will be visible as a straight line on the surface, the light deflection lens (13) is configured so that the visible line on the surface is of generally equal illumination along its entire length. The light beam deflection lens preferably comprises an optical lens which is adapted to refract and reflect the emitted light beam.

L'invention concerne un appareil de projection lumineuse (10) destiné à projeter une ligne d'éclairement sur une surface, et comprenant une source lumineuse (11) émettant un faisceau lumineux et une lentille de déflexion (13) du faisceau lumineux, conçue pour recevoir le faisceau lumineux émis et projeter un faisceau lumineux de travail qui soit visible sous la forme d'une ligne droite sur la surface. Cette lentille de déflexion (13) du faisceau lumineux est configurée de manière à ce que la ligne visible sur la surface présente un éclairement égal, d'une manière générale, sur toute sa longueur. La lentille de déflexion du faisceau lumineux comporte, de préférence, une lentille optique adaptée à la réfraction et à la réflexion du faisceau lumineux émis.
