Abstract

L'invention concerne un dispositif d'éclairage pour système de mesure optique. Ce système comporte des moyens pour engendrer de la lumière, une enveloppe pour pratiquement enclore complètement les moyens pour engendrer de la lumière afin de les protéger de la poussière. Des moyens conducteurs de lumière, exposés à la lumière formée à l'intérieur, dirigent cette lumière vers l'extérieur de l'enveloppe en vue d'éclairer un objet extérieur. De préférence, un réflecteur interne en ellipsoïde est prévu. Application : source de lumière pour colorimètre.
