Abstract

um dispositivo de iluminação para um sistema óptico de um aparelho de leitura que compreende uma fonte de luz (3) disposta concentricamente em torno de um corpo oco anular (2), um refletor de luz externo (5) para redirecionar a luz para iluminar uma zona na sua extremidade distal (5b) e um elemento refletor (8) com uma superfície externa de acabamento espelhado (8a). a parede interna (6) do refletor de luz externo (5) é feita de material refletivo, com uma primeira porção (6a) com seções transversais crescentes de uma extremidade proximal (5a) para uma primeira região (6b) com seção transversal máxima, e uma segunda porção (6c) com seções transversais decrescentes da primeira região (6b) para uma segunda região (6d) com seção transversal mínima. o elemento refletor (8) está disposto em frente à fonte de luz (3) para redirecionar a luz para a primeira porção (6a) do refletor de luz externo (5). o dispositivo de iluminação (1) alcança, em um espaço reduzido, alta eficiência óptica e iluminação uniforme na marca de leitura, evitando a reflexão especular.
