Abstract

"DISPOSITIVO PARA EXIBIçãO DE PROJEçãO" Um dispositivo do tipo para projeção (1), no qual a luz que parte de um sistema ótico de iluminação (80) é difundida por uma micro lente (101) formada em um bulbo luminoso de cristal líquido (100R), esta luz que parte ou é emergente, a qual é difundida pela micro lente (101) a partir do bulbo luminoso de cristal líquido (100R), sendo recebida de forma eficiente em um sistema ótico de projeção (60), um número F do mesmo sendo ajustado de maneira menor do que o do sistema ótico de iluminação (80), fato pelo qual pode ser impedida uma diminuição da eficiência da luz atribuída à difusão da luz pela micro lente (101), o dispositivo do tipo para projeção no qual é incorporada a micro lente que contém o bulbo luminoso de cristal líquido sendo capaz de prover uma projeção de imagem brilhante.
