Title (EN) CATHODE RAY TUBE FOR A LIGHT SOURCE
(FR) TUBE A RAYONS CATHODIQUES POUR UNE SOURCE DE LUMIERE
Abstract: front page image
(EN)A cathode ray tube for a light source includes a fluorescent screen (2) which emits a light of a single color such as red, green, blue, etc. formed on the inner surface of a face plate (3) located at one end of a vacuum envelope (1), and an electron gun (4) mounted at the other end of the vacuum envelope (1) opposite to the fluorescent screen (2). The face plate (3) is composed of a glass containing rare earth oxides Nd2O3 and Pr2O3, thus, it is possible to obtain good color tone and contrast under the sun in the day time.
(FR)Un tube a rayons cathodiques pour une source de lumiere comprend un ecran fluorescent (2) qui emet une lumiere d"une seule couleur par exemple le rouge, le vert, le bleu, etc., forme sur la surface interne d"une plaque (3) situee a une extremite d"une enceinte sous vide (1), et un canon a electron (4) monte a I"autre extremite de l"enceinte sous vide (1) a l"oppose de l"ecran fluorescent (2). La plaque (3) se compose d"un verre contenant des oxydes de terres rares Nd2O3 et Pr2O3. ainsi, il est possible d"obtenir une bonne tonalite de la couleur et de bons contrastes au soleil, de jour.
