Abstract

SE PRESENTA UN DISPOSITIVO DE ILUMINACION (10), QUE SE PUEDE UTILIZAR COMO UN FARO U OTRA LAMPARA EXTERNA DE UN VEHICULO, CUYO GROSOR (REQUERIMIENTO DEL ESPACIO EN TERMINOS DE PROFUNDIDAD) ES MUCHO MENOR QUE LAS DEMAS DIMENSIONES, Y COMPRENDE, AL MENOS, UNA FUENTE DE LUZ (1), UN EXTRACTOR/MODIFICADOR (13) Y, AL MENOS, UN REFLECTOR (3) PARA COLIMAR UN HAZ DE RAYOS LUMINOSOS DESDE LA FUENTE HASTA EL EXTRACTOR/MODIFICADOR (13), EL CUAL ESTA DISEÑADO PARA CONTROLAR LA DIVERGENCIA Y LA DISTRIBUCION DE LA INTENSIDAD DEL HAZ Y DESVIARLO A TRAVES DE UNA LENTE (6) COLOCADA, APROXIMADAMENTE, EN PARALELO CON LA DIRECCION DE PROPAGACION DEL HAZ, EN FRENTE DEL EXTRACTOR/MODIFICADOR; ESTE ULTIMO ES UN SEGUNDO REFLECTOR (13) CON UNA SUPERFICIE EXTERIOR, QUE SE ENCARA DIRECTAMENTE CON LA LENTE, COLOCADA EN OBLICUO CON LA DIRECCION (X) DE PROPAGACION DEL HAZ EN UNA FORMA TAL QUE EL SEGUNDO REFLECTOR (13) TIENE UNA FORMA APROXIMADA DE CUÑA EN SU SECCION TRANSVERSAL EN LA DIRECCION (X) DE PROPAGACION DEL HAZ,CUYA SUPERFICIE SUPERIOR ESTA HECHA DE UNA PLURALIDAD DE RELIEVES ADYACENTES ENTRE SI (15), CADA UNO DE LOS CUALES TIENE, EN LA DIRECCION DE PROPAGACION DEL HAZ, UN PERFIL DE DIENTE VISTO; LOS PICOS (20) DE LOS RELIEVES (15) YACEN TODOS EN UNA CURVA CONTINUA (21) DE UNA FORMA DEFINIDA, Y, PARA CADA RELIEVE (15), LA CARA OBLICUA (16) MAS CERCANA A LA FUENTE DE LUZ (12) YACE EN UN ANGULO DEFINIDO INDIVIDUALMENTE EN RELACION CON LA DIRECCION (X) DE PROPAGACION DEL RAYO.A LIGHTING DEVICE IS PRESENTED (10), WHICH CAN BE USED AS A LIGHTHOUSE OR ANOTHER EXTERNAL LAMP OF A VEHICLE, WHOSE THICKNESS (SPACE REQUIREMENT IN DEPTH TERMS) IS MUCH LESS THAN THE OTHER DIMENSIONS, AND UNDERSTAND, AT LEAST A LIGHT SOURCE (1), AN EXTRACTOR / MODIFIER (13) AND, AT LEAST, A REFLECTOR (3) TO COLLECT A BEAM OF LIGHT RAYS FROM THE SOURCE TO THE EXTRACTOR / MODIFIER (13), WHICH IS DESIGNED TO CONTROL THE DIVERGENCE AND DISTRIBUTION OF THE INTENSITY OF THE BEAM AND DEVICE THROUGH A LENS (6) PLACED, APPROXIMATELY, IN PARALLEL WITH THE ADDRESS OF PROPAGATION OF THE BEAM, IN FRONT OF THE EXTRACTOR / MODIFIER; THIS LAST IS A SECOND REFLECTOR (13) WITH AN EXTERIOR SURFACE, THAT FACES DIRECTLY WITH THE LENS, PLACED IN OBLIQUE WITH THE ADDRESS (X) OF PROPAGATION OF THE BEAM IN A FORM THAT THE SECOND REFLECTOR (13) HAS AN APPROXIMATE FORM IN THE CROSS SECTION IN THE ADDRESS (X) OF THE PROPAGATION OF THE BEAM, WHOSE HIGHER SURFACE IS MADE OF A PLURALITY OF ADDITIONAL RELIEFS BETWEEN (15), EACH OF WHICH HAS, IN THE ADDRESS OF PROPAGATION OF THE BEAM, A TOOTH PROFILE SEEN; THE PEAKS (20) OF THE RELIEFS (15) ALL REMAIN IN A CONTINUOUS CURVE (21) IN A DEFINED FORM, AND, FOR EACH RELIEF (15), THE OBLIQUE FACE (16) CLOSER TO THE SOURCE OF LIGHT (12) IT LIES AT AN INDIVIDUALLY DEFINED ANGLE IN RELATION TO THE DIRECTION (X) OF SPREAD PROPAGATION.
