Abstract
A light guiding device includes a first light guide having an end surface, a corner section and a downstream section. The corner section of the first light guide has a corner and is closer to the end surface of the first light guide than the downstream section. Light incident surfaces of the first light guide include the end surface, and an inner side surface of the corner section located on the inner side of the corner. A light exit surface of the first light guide includes an outer side surface of the first light guide located on the outer side of the corner. The light incident surfaces of the first light guide may additionally include the inner side surface of the corner section. It is found that the corner section can be lit on when the corner section is observed along the direction tangent to the corner section.
