Abstract

"ILUMINADOR DE DOCUMENTO". A presente invenção refere-se a um iluminador de documento, que compreende um elemento transmissivo de luz possuindo um LED de emissão lateral embutido encaixado em uma cavidade formada no mesmo. O elemento transmissivo de luz é formado com um ou mais entalhes ópticos e é totalmente envolvido em uma parte circunjacente branca para produzir a reflexão interna total dos raios de luz emanando a partir do LED. Os raios de luz refletidos são reunidos em uma abertura que por sua vez transmite o perfil de iluminação de alta potência e altamente uniforme para iluminar um documento.
