Abstract

DISPOSITIVO DE ILUMINAÇçO DE FUNDO, E, APARELHO DE EXIBIÇçO DE CRISTAL LÍQUIDO. Um dispositivo de iluminação de fundo, para irradiar luzes em um painel de cristal líquido, compreendendo diversos números de blocos de iluminação de fundo, em que casa bloco de iluminação de fundo tem um membro de reflexão semelhante a folha (19), que é disposto em um semelhante a placa (2), que é provido faceando o membro de reflexão e é disposto separando na direção perpendicular a uma superfície de irradiação de luz de iluminação de fundo do membro de reflexão, para emitir as luzes na direção em paralelo com a superfície de irradiação de luz de iluminação de fundo, por meio do que as luzes dos LEDs, transmitidas através do elemento óptico, propagando-se enquanto sendo refletidas repetitivamente dentro do espaço definido entre o elemento óptico e o membro de reflexão, a fim de serem guiadas sobre a superfície de irradiação de luz da iluminação de fundo e , desse modo, aumentando a eficiência de utilização das luzes da fonte de luz; isto é, provendo uma tecnologia para possibilitar obter uma apropriada saída óptica (por exemplo, uniformidade de brilho), com uma simples estrutura do mesmo.
