Abstract

La présente invention concerne de façon générale des modules d'éclairage et des projecteurs d'images utilisant lesdits modules d'éclairage. La présente invention concerne également une technique visant à réduire la dégradation du polariseur réfléchissant utilisé dans de tels modules d'éclairage, et peut par conséquent conduire à une amélioration du rendement global d'un projecteur d'images sans restriction excessive de sa durée de vie.
