Abstract

Une unité optique (40) comprend une source de lumière (42), un réflecteur rotatif (44) tournant autour de son axe de rotation tout en réfléchissant la lumière émise par la source de lumière (42). La source de lumière comprend des premières parties d'émission de lumière configurées pour émettre une première lumière afin de balayer une première région comprenant une région d'intensité lumineuse maximum du motif de distribution de lumière, et des deuxièmes parties d'émission de lumière configurées pour émettre une deuxième lumière afin de balayer une deuxième région adjacente à la première région. Lorsqu'une somme des longueurs des premières parties d'émission de lumière dans une direction longitudinale est exprimée par L1 et qu'une somme des longueurs des deuxièmes parties d'émission de lumière dans une direction parallèle à la direction longitudinale des premières parties d'émission de lumière est exprimée par L2, une relation de L1 > L2 est satisfaite.
