Abstract

UNA GUIA LIGERA (10) PARA ILUMINAR UNA PANTALLA Y/O UN TECLADO SE FORMA CON MATERIAL TRANSLUCIDO CON UN ELEMENTO PLANAR QUE TIENE UN BORDE PERIFERICO (24). EN UN LADO HAY FORMADOS UNA PLURALIDAD DE ENCASTRES DE ACOPLAMIENTO LUMINOSOS DE FORMA CURVADA (150) PARA TRANSMITIR LA LUZ DESDE LAS FUENTES DE LUZ DE MANERA SUSTANCIALMENTE UNIFORME DENTRO DE LA GUIA DE LUZ (10). EN EL BORDE PERIFERICO (24) SE FORMAN UNA PLURALIDAD DE ENCASTRES REFLECTANTES DE LA LUZ (60, 62) PARA REFLEJAR LA LUZ EN EL BORDE DE NUEVO HACIA LA GUIA DE LUZ (10) DE UNA FORMA UTIL PARA ILUMINAR LAS CLAVES DEL DISPOSITIVO.
