Abstract
A light flux controlling member includes an incidence region and an emission region. The incidence region includes a refraction part on which a part of the light emitted from the light emitting element is incident, the refraction part being disposed at a center portion of the incidence region and configured to refract the incident light such that the incident light travels away from an optical axis of the light emitting element, and a reflection part on which another part of the light emitted from the light emitting element is incident, the reflection part being disposed outside the refraction part and configured to reflect the incident light such that the incident light approaches the optical axis. The emission region has an area smaller than a projection area of the light flux controlling member and emits light reflected by the reflection part such that the light approaches the optical axis.
