Abstract

L'invention concerne un masque de protection en cristaux liquides pour des opérations de soudage permettant de protéger les yeux d'un opérateur humain d'une lumière en arc produite au cours d'une opération de soudage. Ce masque comporte un corps principal de masque de protection en cristaux liquides adapté de manière à être fixé au visage d'un opérateur humain, des moyens de détection disposés à proximité du corps principal de masque de protection en cristaux liquides et capables de détecter une lumière en arc incidente produite lors d'une opération de soudage et produisant ainsi un résultat de détection, une section en cristaux liquides arrêtant la lumière et placée de manière à correspondre aux yeux de l'opérateur humain portant le masque de protection, le visage humain étant recouvert par le corps principal de masque de protection et possédant un membre en cristaux liquides capable de bloquer la lumière incidente en réduisant instantanément la capacité de transmission de lumière des cristaux liquides en fonction de la production du résultat de détection par les moyens de détection et grâce à des cristaux liquides dirigeant la source d'alimentation et une plaque de polarisation placée devant les moyens de détection afin de couvrir les moyens de détection et pouvant contrôler l'orientation de la lumière incidente.
