Abstract

UN SIGNO ILUMINADO INTERIORMENTE EMPLEA UN RECUBRIMIENTO RETRORREFLEXIVO CON UNIONES TRANSMISIBLES OPTICAMENTE ENTRE UNA CAPA DE RECUBRIMIENTO Y UNA CAPA BASICA, HACIENDO A LA SEÑAL ADECUADA PARA SU APLICACION CUANDO SE PRECISE LA VISIBILIDAD DEL SIGNO SI FALLA LA FUENTE DE ILUMINACION. UN CONDUCTO DE LUZ PUEDE SER EMPLEADO PARA POSIBILITAR QUE LA FUENTE DE ILUMINACION INTERNA SE ENCUENTRE ALEJADA DEL INTERIOR DE LA CAJA DE SEÑALIZACION. SE PUEDE UTILIZAR ASIMISMO UN RECUBRIMIENTO DE REFLEXION TOTALMENTE INTERNA PARA DIFUNDIR LA ILUMINACION INTERIOR.
