Abstract

LA INVENCION SE REFIERE A INDICADORES EN CUYA PARTE POSTERIOR SE DISPONEN FUENTES LUMINOSAS PARA ILUMINAR DESDE ATRAS UNA PANTALLA DE CRISTAL LIQUIDO (LCD). UN REFLECTOR SITUADO ENTRE LA FUENTE LUMINOSA Y EL LCD SE ENCARGA DE LA DISTRIBUCION UNIFORME DE LA LUZ POR TODO EN LCD. LOS INCONVENIENTES DE ESTOS DISPOSITIVOS CONOCIDOS SON SU PROFUNDIDAD RELATIVAMENTE GRANDE Y LA CIRCUNSTANCIA DE QUE ES PRECISO UTILIZAR CIERTA CANTIDAD DE PIEZAS ADICIONALES COMO ELEMENTOS DE SUJECION. PARA QUE EL INDICADOR TENGA UNA ESTRUCTURA COMPACTA CON UNA PROFUNDIDAD RELATIVAMENTE PEQUEÑA, EL REFLECTOR (27) ESTA CONFORMADO COMO ELEMENTO SEPARADOR. UNOS TOPES (32) LATERALES SIRVEN COMO SEPARADORES PARA FIJAR LA DISTANCIA ENTRE EL LCD SITUADO ENCIMA Y LA PLACA DE CIRCUITO IMPRESO DISPUESTA EN LA CARA LONGITUDINAL OPUESTA DEL REFLECTOR (27). EL REFLECTOR TIENE, ADEMAS, ELEMENTOS CON ENTALLADURAS (30) MEDIANTE LOS CUALES SE ENGANCHA A LA PLACA DE CIRCUITO IMPRESO. EQUIPO INDICADOR PARA VEHICULOS.
