Abstract

L'invention a trait à un module optique d'éclairage et/ou de signalisation (2), notamment pour véhicule automobile, comprenant au moins une source de lumière du type laser (6) apte à émettre un rayonnement lumineux spatialement et temporellement cohérent, un dispositif de conversion (8) du rayonnement lumineux spatialement et temporellement cohérent en lumière blanche, et un dispositif optique (10) apte à recevoir la lumière blanche du dispositif de conversion en vue de former un faisceau lumineux d'éclairage et/ou de signalisation. Le module (2) comprend également un détecteur constitué d'un élément optique (14) et d'un capteur de lumière (16), préférentiellement du type photodiode, l'élément optique (14) étant configuré pour dévier les rayons de la lumière blanche du dispositif de conversion (8) vers le capteur (16).
