Abstract

L'invention concerne un système d'éclairage par projection (1) comportant un dispositif d'éclairage (3) pourvu d'une source lumineuse, en particulier un laser émetteur de lumière ultraviolette, un objectif de projection (7), un plan réticule dans lequel est placé un réticule (5), un plan tranche dans lequel est placée une tranche (2) ainsi qu'un système à gaz de lavage permettant de laver l'intérieur de l'objectif de projection (7) et/ou les zones extérieures, en particulier les plans réticule et tranche. Ledit système comporte au moins un dispositif (25, 32, 33) destiné à surveiller au moins un flux de gaz de lavage, lequel dispositif interrompt le rayonnement de la source lumineuse vers l'objectif de projection (7) lorsque la limite inférieure d'un débit de gaz de lavage prescrit est dépassée. Ce dispositif (25, 32, 33) destiné à surveiller le flux de gaz de lavage est relié à la source lumineuse par l'intermédiaire d'un dispositif de commande, lequel dispositif de commande (27) est équipé d'une minuterie (36).
