Abstract
(EN) Disclosed is an optical unit wherein a rotating reflector (26) rotates in one direction with a rotating axis at the center, while reflecting light emitted from a light source. The rotating reflector (26) is provided with a reflecting surface such that the light reflected by the rotating reflector, while rotating, forms a desired light distribution pattern, said light having been emitted from the light source. The light source is composed of light emitting elements. The rotating axis is provided within a plane that includes an optical axis and the light source. The rotating reflector (26) is provided with, on the periphery of the rotating axis, a blade that functions as the reflecting surface.
(FR) La présente invention concerne une unité optique dans laquelle un réflecteur rotatif (26) tourne dans une direction avec un axe de rotation central, tout en réfléchissant la lumière émise par une source lumineuse. Le réflecteur rotatif (26) est pourvu d'une surface réfléchissante afin de permettre à la lumière réfléchie par le réflecteur rotatif de former, tout en tournant, un schéma de distribution lumineuse souhaité, ladite lumière ayant été émise par la source lumineuse. La source lumineuse se compose d'éléments électroluminescents. L'axe de rotation se trouve dans un plan qui comprend un axe optique et la source lumineuse. Le réflecteur rotatif (26) est doté, à la périphérie de l'axe de rotation, d'une lame qui fait office de surface réfléchissante.
