Abstract

EL FARO DE VEHICULO APANTALLADO SEGUN EL PRINCIPIO DE PROYECCION MUESTRA UNA PANTALLA (3) FIJA COLOCADA ENTRE LA LENTE COLECTORA (2) Y EL REFLECTOR (1), CUYO CANTO APANTALLADO (9) PRODUCE EL LIMITE CLARO-OSCURO DE UNA DISTRIBUCION ASIMETRICA DE LUZ. ADEMAS DE LA PANTALLA FIJA (3) MUESTRA EL FARO UNA PANTALLA AJUSTABLE (4) EN UNA POSICION ACTIVA Y DE DESCANSO. EN LA POSICION ACTIVA DESARROLLA LA PANTALLA SUS CANTOS APANTALLADOS (13) EN LA PARTE SUPERIOR Y EN LA POSICION DE DESCANSO EN LA PARTE INFERIOR DE LA PARTE DE LOS CANTOS APANTALLADOS FIJOS QUE PRODUCEN LA ASIMETRIA DE LA FIGURA LUMINOSA.THE VEHICLE HEADLIGHT SCREENED ACCORDING TO THE PROJECTION PRINCIPLE SHOWS A FIXED SCREEN (3) PLACED BETWEEN THE COLLECTOR LENS (2) AND THE REFLECTOR (1), WHOSE SCREEN EDGE (9) PRODUCES THE CLEAR-DARK LIMIT OF AN ASYMMETRICAL DISTRIBUTION . IN ADDITION TO THE FIXED SCREEN (3) THE LIGHTHOUSE SHOWS AN ADJUSTABLE SCREEN (4) IN AN ACTIVE AND REST POSITION. IN THE ACTIVE POSITION, THE SCREEN DEVELOPS ITS SCREENED EDGES (13) IN THE UPPER PART AND IN THE REST POSITION IN THE LOWER PART OF THE PART OF THE FIXED SCREENED EDGES THAT PRODUCE THE ASYMMETRY OF THE LIGHT FIGURE.
