Light conducting plate for surface light source device and method for the manufacture thereof |
摘要 |
A light conducting plate for a surface light source device wherein a linear light source is disposed at a light entrance edge at at least one end of a light conducting plate whose one surface is provided with a reflecting layer and whose other surface is defined as a light-emitting surface. The light of the linear light source is scattered within the interior of the light conducting plate by the reflecting layer and emitted from the light-emitting surface. The light conducting plate for a surface light source device is constituted by forming the reflecting layer by moving a bit along the surface of the light conducting plate to be formed with the reflecting layer while pressing it thereon at a negative rake angle to continuously form hole-like pits of random depth and width by fracturing of the surface to be formed with the reflecting layer as a result of exceeding its elastic limit, and forming a plurality of the pit rows in which the pits are continuously aligned.
