Abstract

L'invention concerne un revêtement teinté et traité aux rayons ultraviolets pour lampes à éclair, destiné à protéger l'enveloppe de la lampe et à effectuer la correction requise des couleurs. Selon l'un des modes de réalisation, le revêtement est constitué par un photopolymère teinté au moyen d'un premier colorant constitué par une teinture ou un pigment. Le boîtier en plastique transparent où est disposée la lampe est également teinté au moyen d'un second colorant de telle manière que ce dernier présente une absorption maximale pour des longueurs d'onde sensiblement différentes de celles du revêtement teinté. Application à tous les types de lampes à éclair.
