Abstract
UN DISPOSITIVO DE ILUMINACION CON UNA FUENTE DE LUZ Y UNA CUBIERTA SUSTANCIALMENTE NO ABSORBENTE DE LUZ. LA TRANSMISIVIDAD DE LUZ DE LA CUBIERTA EN CUALQUIER PUNTO DE LA CUBIERTA VARIA EN FUNCION DE LA POSICION DE ESE PUNTO, DE TAL FORMA QUE LA LUMINANCIA DE LUZ QUE ESCAPA A TRAVES DE LA CUBIERTA EN ESE PUNTO TIENE UNA SALIDA LUMINOSA SELECCIONADA COMO UNA FUNCION DE LA POSICION DE ESE PUNTO.
