Abstract

LA INVENCION SE REFIERE A UN PROYECTOR PARA VEHICULO AUTOMOVIL QUE COMPRENDE UNA FUENTE LUMINOSA REAL (101), UN ESPEJO ELIPTICO (102) Y UN CONDUCTOR DE LUZ (200) PROVISTO DE UNA PLURALIDAD DE FACETAS (210A, 220A, 220B, 230A, 240A) QUE CONSTITUYEN OTRAS TANTAS FUENTES LUMINOSAS VIRTUALES QUE COOPERAN CON ELEMENTOS DIOPTRICOS HOMOLOGOS PARA CONSTITUIR UN CONJUNTO DE HACES LUMINOSOS ELEMENTALES QUE SE FUNDEN EN UN HAZ UNICO. SEGUN LA INVENCION, EL CONDUCTO DE LUZ CONSTA DE UNA PLURALIDAD DE LAMINAS TRANSPARENTES (210, 220, 230, 240...) DE VIDRIO YUXTAPUESTAS QUE SE EXTIENDEN A LO LARGO DEL EJE LONGITUDINAL DE DICHO CONDUCTO DE LUZ Y QUE INCLUYE CADA UNA AL MENOS EN SU EXTREMO MAS ALEJADO DE LA FUENTE LUMINOSA REAL UNA FACETA DE REFLEXION OBLICUA (210A, 220A, 230A, 240A, ...); DICHAS FACETAS ESTAN DISPUESTAS DE MANERA QUE COOPERAN OPTICAMENTE CON LOS MENCIONADOS ELEMENTOS DIOPTRICOS DE EJE PARALELO A LA DIRECCION DE ILUMINACION (E) PARA QUE PROYECTEN EN ESTA DIRECCION IMAGENES QUE SE CORRESPONDEN CON LAS FACETAS.
