Abstract

"PAINEL LUMINOSO DE LUZ DIFUSA COM BAIXO CONSUMO DE ENERGIA E ESPESSURA LIMITADA". Um painel luminoso de luz difusa com baixo consumo e baixa espessura, útil para letreiros de propaganda, sinais de caminho, sinais de trânsito, elementos de mobilia luminosos etc. consistindo de uma primeira placa condutiva de luz (1) em material transparente, coberta no seu lado traseiro com um revestimento de tinta branca (6) ou com uma pelicula adesiva ou colada, consistindo de conjuntos de diodo emissor de luz lineares (2) encaixados em uma, duas ou mais bordas da placa transparente (1) acima mencionada, repousando sobre suportes adequados (3) usualmente representados por circuitos impressos energizados em sequência, consistindo de elementos (5) de reflexão da luz dos diodos emissores de luz localizados entre os suportes (3) e a borda polida da placa transparente (1), consistindo de uma segunda placa de vidro opalino transparente (7), que faz difusão da luz que vem da superfície da placa acima mencionada (1), consistindo de uma terceira placa protetora (8), posicionada em frente da segunda placa (7), e útil para fixação dos anúncios a serem iluminados, e consistindo de seções formatadas adequadamente (9) estruturando os quatro lados das placas (1, 7, 8) e dos diodos emissores de luz (2) aptas a formar uma armação periférica (9) completada nos seus cantos por cantoneiras (10).
