ABSTRACT:
An apparatus for homogeneously distributing lights includes a light guide plate, an incidence microstructure and an emergence microstructure. The incidence microstructure is arranged on a surface of the light guide plate and opposite to a light source. The emergence microstructure is arranged on a surface of the light guide plate opposite to the incidence microstructure. The lights emitted by the light source pass through said apparatus thereby being homogenously distributed. Thus the manufacture costs are lowered, and the light source utilization ratio is increased.
