Abstract

Una fuente de luz que incluye un cátodo de emision por campo, y un cátodo de emision por campo. La fuente de luz comprende un recipiente evacuado que tieneparedes, por lo menos una porcion de las cuales consiste de una capa de vidrio exterior (23, 23) la cual, sobre al menos una parte principal de la misma, estárevestida sobre el lado interior con una capa de fosforo (20, 24) que forma una capa luminiscente y una capa conductora (25, 25) que forma un ánodo. La capade fosforo (24, 24) es excitadahasta luminiscencia por bombardeo de electrones desde un cátodo de emision por campo (40, 40) ubicado en el interior delrecipiente. Un electrodo modulador está dispuesto entre el cátodo (40, 40) y el ánodo (25, 25) para crear un campo eléctrico necesario para la emision deelectrones. El cátodo de emision por campo (40,40) incluye un nucleo que se extiende longitudinalmente (41, 41) que tiene un eje central, y cuerpos emisorespor campo (42, 42) que se extienden desde el nucleo (41, 41). Los cuerpos emisores por campo (42, 42) son alargados y están distribuidos a lo largo de porlo menos una parte de la longitud del nucleo (41, 41). Los cuerpos emisores de campo (42, 42) se extienden radialmente hacia afuera desde el nucleo (41, 41)y tienen extremos libres provistos con superficies emisoras por campo.
