摘要：
A reflector has a curved part covering the light source and a pair of end parts extending at the two sides of the curved part. The inside surface of each end part has a plurality of substantially parallel projections or depressions. The light-guiding plate has an incident surface and an emission surface substantially perpendicular to the incident surface, the incident surface having a plurality of projections or depressions extending substantially parallel to the emission surface. Also, the reflection surface of the light-guiding plate has projections.
