Abstract

UN DISPOSITIVO DE ILUMINACION, POR EJEMPLO UN DISPOSITIVO DE ILUMINACION PARA UN ALUMBRADO DE EMERGENCIA QUE CONSTA DE UNA FUENTE LUMINOSA (1) Y DE UN ELEMENTO OPTICO (3) MONTADO DETRAS DE LA FUENTE LUMINOSA. EL ELEMENTO ESTA CONFORMADO A MODO DE ELEMENTO TIPO FRESNEL DE TAL MODO QUE SUSTANCIALMENTE TODA LA LUZ QUE INCIDA EN EL MISMO PROCEDENTE DE LA FUENTE LUMINOSA SEA REDIRIGIDA A UN ANGULO ESPECIFICO, NORMALMENTE DE 60 (GRADOS) RESPECTO AL EJE CENTRAL DEL DISPOSITIVO DE ILUMINACION. EL ELEMENTO AUMENTA LA SALIDA DE LUZ SOBRE UN AREA ESPECIFICA.
