| 20100284183 | LIGHT GUIDING MECHANISM FOR PORTABLE ELECTRONIC DEVICE - A light guiding mechanism for portable electronic device includes a cover, a light guiding module and four light sources. The cover includes a light transmitting region. The light guiding module includes a light guide plate having a first diagonal line and a second diagonal line. The light guide plate defines a first through hole. The light guide plate includes a light reflecting region around the first through hole. The light reflecting region includes a plurality of protrusions symmetrically positioned relative to the first diagonal line and the second diagonal line. Adjacent protrusions have a space therebetween. The size of the space uniformly increases with increasing distance from the first through hole. Light emitted from the light sources is repeatedly reflected by the protrusions and then passes the light transmitting region of the cover. | 11-11-2010 |
