Abstract

luminária com exposição de fundo usando pixels difusos entre fontes de luz-difusas um dispositivo de iluminação com um número de fontes de luz dispostas em pelo menos dois grupos de fontes de luz que são controláveis individualmentes . o primeiro grupo de fontes de luz (205) tem coletores de luz, como lentes de reflexão interna (tir), misturadores ou outras lentes colocadas sobre elas para coletar e converter a luz de fontes de luz em número de feixes de fonte de luz . o segundo grupo de fontes de luz (209) é organizado em uma matriz de pixels com a saída de luz entre o primeiro grupo de fontes de luz. a matriz de pixels pode ser controlada com base em um sinal de vídeo. a luz de cada pixel pode ser difundida na saída , passando por áreas difusivas de uma tampa difusora. os feixes de fonte de luz não são difundidos ,por a luz deles passa por regiões não- difusas do difusor. o dispositivo de iluminação pode ser incluído em uma fonte de luz com cabeça móvel com uma base , jugo rotacionamente conectado à base e a cabeça rotacionalmente conectada à cabeça. o segundo grupos de fontes de luz (703, 209) pode passar luz através de guias de luz ou tubos de luz (713a) e tem uma seção de saída (717a-718b) entre pelo menos dois feixes de fonte de luz.
