LIGHT GUIDE MEMBER, ILLUMINATING DEVICE USING THE LIGHT GUIDE MEMBER, AND LIGHT GUIDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a light guide member which easily enables downsizing of the whole member (device) since the light guide member which can make light emit from the whole face in an emitting direction can be achieved and its large-sizing to obtain a light-emitting face (outgoing part) of a desired size is not necessary, to provide a light source device using the light guide member, to provide an illuminating device using the light guide member, and to provide a light guiding method using the light guide member.

SOLUTION: The light guide member has a molding part 12a which totally reflects light emitted from a light source 2 by guiding the light from the incident part 11 and which further reflects the totally reflected light on a reflecting face and emits it.
