The multiple directivity lightpipe which accompanies the side dispersion which was adjusted

摘要

This invention, when turning on power in the equipment, deals with the lightpipe which is used in order illuminating light to do portion of the surface of the set top box. As for this lightpipe, for example, it is possible to form from the plastic. This lightpipe profitably, should make the ideal conveying body of the photon which passes by the route of rectilinear condition. Furthermore lightpipe should try to be able to transmit light outside the partial side.
