Abstract
LA INVENCION SE REFIERE A UNA CAJA LUMINOSA PARA UN DISPOSITIVO DE VISUALIZACION AVIONICA, CONTENIENDO ESTE DISPOSITIVO UNA PANTALLA DE CRISTALES LIQUIDOS QUE TRANSMITEN LA LUZ SUMINISTRADA POR LA CAJA LUMINOSA. CONTIENE UN PRIMER DISPOSITIVO DE ILUMINACION, QUE TIENE TRES TUBOS FLUORESCENTES (1, 3, 5) QUE TIENEN UN FOSFORO QUE EMITE UNA LUZ BLANCA QUE PERMITE UNA VISUALIZACION POLICROMA, CON UNA INTENSIDAD LUMINOSA SUFICIENTE PARA OBTENER UN BUEN CONTRASTE A PLENO DIA; UN DISPOSITIVO DE CONMUTACON (13) PARA APAGAR EL PRIMER DISPOSITIVO DE ILUMINACION CUANDO SE HACE NOCHE; UN SEGUNDO DISPOSITIVO DE ILUMINACION QUE TIENE DOS TUBOS FLUORESCENES (2, 4) DE TALLA INFERIOR A LA DE LOS PRECEDENTES, QUE PRODUCE UNA INTENSIDAD INFERIOR A LA EMITIDA POR EL PRIMER DISPOSITIVO DE ILUMINACION DE DIA, Y DE COLOR VERDE, ESPECIALMENTE POBRE EN INFRARROJOS, PARA SER COMPATIBLE CON LA UTILIZACION DE ANTEOJOS DE BAJO NIVEL DE LUZ QUE AMPLIAN LOS INFRARROJOS. APLICACION A LOS DISPOSITIVOS DE VISUALIZACION INCORPORADOS EN LOS CUADROS DE LOS AVIONES MILITARES.
