Ledit protecteur comprend : un masque (1), un écran de verre (2), un récepteur d'énergie solaire (11), un panneau à cristaux liquides (3) et un système de circuits. La pile solaire (11) est montée sur le masque (1). Le panneau à cristaux liquides (3) est monté sur la surface intérieure de l'écran de verre (2). Le système de circuits comprend un circuit de commande (20), un circuit générateur haute tension (30) et un circuit d'entraînement (40). Le panneau à cristaux liquides (3) est raccordé à la sortie du circuit d'entraînement (40). L'énergie solaire reçue par le récepteur d'énergie solaire (11) est stockée dans une batterie solaire et sert de source d'alimentation (10) pour le système de circuits. Cette source d'alimentation (10) est raccordée au circuit d'entraînement (40) par l'intermédiaire du circuit de commande (20) et du circuit générateur haute tension (30).
