Abstract: front page image
(EN)An apparatus comprising a switchable optical filter comprising a layer of switchable material, the switchable material comprising a photochromic/thermochromic, a photochromic/photochromic, or a photochromic/electrochromic compound; a first light source providing light of a wavelength that causes the switchable material to transition from a faded state to a dark state, or a dark state to a faded state; and a switch for controlling activation of the first light source
(FR)La présente invention concerne un appareil comprenant : un filtre optique commutable comportant une couche en un matériau commutable contenant un composé photochrome/thermochrome, photochrome/photochrome ou photochrome/électrochrome ; une première source de lumière produisant une lumière ayant une longueur d'onde qui fait passer le matériau commutable d'un état estompé à un état sombre et inversement ; et un commutateur permettant de commander l'activation de la première source de lumière.
