Abstract

Dispositif d'éclairage à plusieurs sources lumineuses, dont chacune est équipée d'un réflecteur orientable et qui sont disposées dans un boîtier commun de manière à permettre l'émission simultanée d'un rayonnement dans différentes directions. Les sources lumineuses sont des lampes électriques à décharge dans un gaz, le dispositif pouvant avantageusement être conformé en appareil électronique à éclats permettant l'éclairage soit direct, soit indirect, soit simultanément direct et indirect d'un objet. Application notamment en photographie.
