Light emitting device having luminous flux control member with recess radially distant from a light incident surface

A light-emitting device, comprising:

• a light-emitting element defining an optical axis;
• and
• a light flux controlling member configured to control a distribution of light emitted from the light-emitting element, wherein the light flux controlling member includes
• an incidence surface disposed to intersect the optical axis, the incidence surface being configured to receive light emitted from the light-emitting element,
• a rear surface extending radially outward from an outer edge of the incidence surface, the rear surface surrounding the incidence surface,
• a reflection surface opposite the rear surface, the reflection surface being configured to reflect light received by the incidence surface,
• an emission surface connecting the rear surface and the reflection surface, the emission surface being configured to output light received by the incidence surface, and
• a first recess formed on the rear surface, the first recess being farther from the optical axis than the incidence surface, the first recess including a first inclined surface closer to the front side with increasing distance from the optical axis, and
• wherein a front end of the first inclined surface is located such that a substantial portion of light that is emitted from a center region of a light-emitting surface of the light-emitting element and reflected by the reflection surface do not strike the first inclined surface and such that a substantial portion of light that is emitted from peripheral region of the light-emitting surface of the light-emitting element and not reflected by the reflection surface strikes the first inclined surface.
