Abstract
Light flux controlling memberincludes first light flux controlling memberand second light flux controlling member. First light flux controlling memberincludes incidence surfaceon which a part of light emitted from light-emitting elementis incident, total reflection surfacethat reflects a part of light incident on incidence surfacetoward second light flux controlling member, and emission surfacethat emits a part of light incident on incidence surfaceand light reflected by total reflection surface. Second light flux controlling memberincludes reflection surfacethat reflects a part of light emitted from first light flux controlling member. Reflection surfaceis a rotational symmetric surface with the optical axis LA of light-emitting elementas a rotation axis.
