摘要

The one-piece blind has a light conducting layer and a light source which is arranged at the edge of the light conducting layer and is coupled with the light conducting layer. The surface of the light conducting layer radiates a predetermined portion of the light from the light source. The position, brightness and reflected beam angle of the light source are adjusted so that the radiation amount of light at each point of the light conducting layer is defined.
