Abstract: A light flux controlling member includes n incidence units for allowing incidence of light emitted from n light emitting elements, respectively; an emission unit disposed between the n incidence units and allowing emission of the light incident on the n incidence units while guiding the light; and a plurality of legs. Each incidence unit includes an incidence surface and a reflection surface reflecting, in a direction along the substrate, the light incident on the incidence surface. The emission unit includes a first emission surface emitting a part of the light from the incidence unit, and a second emission surface disposed so as to face away from the first emission surface and emitting another part of the light from the incidence unit. Each leg is disposed at a position satisfying a predetermined condition.

Abstract: A luminous flux control member has: an incident surface, an emission surface; a back surface; and a plurality of recessed or projecting first quadrangular pyramid parts placed in grid form on at least a portion of the back surface. The first quadrangular pyramid part includes: a first inclined plane that is inclined so as to face the back side as separation increases from the central axis; a second inclined plane that is inclined so as to face the front side as separation increases from the central axis; and a connecting part that connects the first inclined plane and the second inclined plane. In a cross section including the central axis and the center of the connecting part, the first inclined plane is larger than the second inclined plane.
