Abstract

EL FARO PRESENTA UN REFLECTOR (10), QUE ESTA DIVIDIDO EN CUATRO SEGMENTOS CON DIFERENTES SUPERFICIES DE REFLEXION. EN EL REFLECTOR (10) SE HA INSERTADO UNA LAMPARA DE INCANDESCENCIA (14) CON UN FILAMENTO AXIAL (16), QUE SE EXTIENDE APROXIMADAMENTE A LO LARGO DEL EJE OPTICO (18) DEL REFLECTOR (10). EL REFLECTOR (10) ESTA LIMITADO HACIA ARRIBA Y HACIA ABAJO POR MEDIO DE SUPERFICIES PLANAS (30, 32). LA SUPERFICIE LIMITADORA INFERIOR (32) ESTA PROVISTA DE UNA CAPA REFLECTANTE, Y ESTA INCLINADA HACIA ABAJO RESPECTO AL EJE OPTICO (18) EN LA DIRECCION A LA LUZ, EN UN ANGULO O DE APROXIMADAMENTE DE 5 HASTA 7 (GRADOS) . LA LUZ EMITIDA DESDE EL FILAMENTO DE LA LAMPARA Y REFLEJADA POR LOS SEGMENTOS INFERIORES DEL REFLECTOR (10), SOBRE LA SUPERFICIE LIMITADORA INFERIOR (32), ES REFLEJADA LIGERAMENTE HACIA ABAJO RESPECTO AL EJE OPTICO, COMO CONSECUENCIA DE ESTA DISPOSICION DE LA SUPERFICIE LIMITADORA INFERIOR (32), APROXIMADAMENTE EN PARALELO O EN DIRECCION A LA LUZ. LA LUZ REFLEJADA POR LA SUPERFICIE LIMITADORA INFERIOR (32) PUEDE, POR LO TANTO, UTILIZARSE PARA LA PRODUCCION DE LA PROPIA DISTRIBUCION DE LA LUZ DEL REFLECTOR (10).
