Abstract

Dispositivo óptico que suministra un haz luminoso directivo a partir de una fuente luminosa que se presenta en forma de una lámpara tubular, caracterizado porque comprende: un primer reflector que presenta un perfil parabólico, capaz de enviar dicho haz luminoso hacia la zona útil que debe ser iluminada en una dirección que forma con el eje que pasa por el foco de la fuente y el eje de la parábola, un ángulo diferente de cero; y un segundo reflector que presenta un perfil elíptico, capaz, al tiempo que desempeña la función de pantalla, de reflejar hacia el primer reflector parabólico los rayos luminosos que recibe.
