LUMINOUS FLUX CONTROL MEMBER, LIGHT EMITTING APPARATUS, AND ILLUMINATING APPARATUS

摘要

A luminous flux control member (120) has: a light input surface (121) having inputted thereto light that has been outputted from a light emitting element (110); a total reflecting surface (122) which totally reflects a part of the light inputted from the light input surface (121); and a light output surface (123), which outputs a part of the light inputted from the light input surface (121), and the light reflected by the total reflecting surface (122). The light output surface (123) of the luminous flux control member (120) has a substantially toroidal shape or a saddle-like shape.
