    • The invention is directed to a lighting system having a reflector, light sources and a light control member sequentially disposed from a light incident side to a light outgoing side. Preferably used for large displays requiring high uniformity, this invention eliminates lamp image and removes the necessity to do light source repositioning, while enabling luminance in the exit plane to achieve excellent luminosity and uniformity. This invention achieves total light transmittance of more that 50% when light is incident at a predetermined angle α from the normal direction of the incident plane and achieves 1.05-3 times more total light transmittance than when the light is from a direction normal to the incident plane. This is achieved by the light control member by controlling the ration between total light transmittance in the positions of greater transmittance and the total transmittance in the positions of lesser transmittance.
    • 本发明涉及一种照明系统,其具有从光入射侧顺序地设置到光出射侧的反射器,光源和光控制部件。 本发明优选地用于需要高均匀性的大型显示器,从而消除了灯图像,并且消除了进行光源重新定位的必要性,同时使出口平面中的亮度能够获得优异的发光度和均匀性。 当光以入射平面的法线方向以预定角度α入射时,本发明实现了大于50%的全光线透射率,并且与光线从垂直于入射方向的方向相比,总光线透射率达到1.05-3倍 飞机 通过控制光透射率比较高透射率的位置处的全光线透射率与透射率较低的位置的总透光率之间的比例,由光控制部件实现。
