Abstract

En un panel de instrumentos (1), un dispositivo de retroalimentación de LED (10) tiene por lo menos una fuente de LED (21), cuyo eje óptico (22) corresponde a la dirección en la cual la intensidad de la luz emitida es máxima; la luz de la fuente de LED (21) es reflejada sobre un área gráfica (5a) por medio de una primera y segunda superficies reflexivas (16, 25); la primera superficie (16) define una primera cavidad (13) y está alineada con el área gráfica (5a) a lo largo de un eje de iluminación (17) espaciado del eje óptico (22), mientras que la segunda superficie (27) está alineada con la fuente de LED (21) a lo largo del eje óptico (22) y define una segunda cavidad (25) que comunica con la primera cavidad (13) a través de una abertura (26); la segunda superficie (27) es una superficie cilíndrica, definida por una generatriz elíptica y configurada de tal manera que bloquea los rayos de luz que serían dirigidos desde la fuente de LED (21) sobre el área gráfica (5a).
