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.
Claims11
An apparatus for homogeneously distributing lights, comprising
- a single-layered light guide plate comprising an incidence surface and an emergence surface each of which defines a plurality of interlaced first areas and second areas, wherein each of the first areas is smaller than any of the second areas;
- an incidence microstructure being arranged on the first areas of the incidence surface of the light guide plate and directly in front of and opposite to a light source;
- and
- an emergence microstructure, the emergence microstructure being arranged on the second areas of the emergence surface of the light guide plate opposite to the incidence microstructure;
- wherein light emitted by the light source passes through said apparatus thereby being homogeneously distributed.
