Abstract

See full text

A light guiding device is applied to an indication apparatus with a lighting function. The light guiding device includes a light guiding component and a piercing hole structure. The light guiding component has an incident surface and an emergent surface. The piercing hole structure is disposed between the incident surface and the emergent surface. An inner wall of the piercing hole structure includes at least one arc surface portion and at least one plane surface portion. Alight beam from the incident surface can be turned to a first angle via the arc surface portion, and the light beam can be turned to a second angle via the plane surface portion, so as to evenly project the light beam onto the emergent surface. A dimension of the emergent surface is greater than a dimension of the incident surface, and the first angle is greater than the second angle.
