Abstract
Aparato de alumbrado sin sombras proyectadas, caracterizado porque comprende, al menos, la siguiente combinación de medios: una fuente luminosa, una superficie reflectante de revolución, y un espejo de elementos radiales dióptricos, consistiendo la función de cada elemento en obtener, por refracción, y a ambos lados de un plano radial, una dispersión de un haz de luz reflejado por una parte de la citada superficie reflectante, en la proximidad de una generatriz, tal que la mancha elemental luminosa obtenida sobre un plano sea un cuadrilátero luminoso.
