Abstract

L'invention concerne un appareil et un procédé permettant de recouvrir le système optique d'un appareil d'éclairage à tête mobile grâce à un filtre ou un diffuseur lorsque l'appareil d'éclairage est éteint. Le filtre ou le diffuseur est positionné dans le trajet optique entre un élément d'éclairage et une lentille. Un dispositif de rétraction est excité afin de rétracter le filtre ou le diffuseur à partir du trajet optique pendant un fonctionnement normal. Lors de l'arrêt de l'alimentation de l'appareil, le mécanisme de filtre remet automatiquement le filtre ou le diffuseur à sa position dans le trajet optique. De cette manière, le système optique de l'appareil peut être protégé contre les dommages causés par une lumière incidente intense et/ou la lumière du soleil lorsque l'appareil n'est pas utilisé.
