摘要： 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.

摘要： A lighting system, a reflector, light sources and a light control member are 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 transmittance of more than 50% when light is incident on the normal direction of the incident plane at a predetermined angle α and achieves 1.05-3 times more total transmittance than when the light is normally incident. This is achieved by using a light control member such as the light diffusion plate described herein, which is conformed to obtain required luminosity and uniformity by controlling the ratio between total transmittance in the positions of greater transmittance and the total transmittance in the positions of lesser transmittance.
