Abstract:
This luminous flux control member has: a plane of incidence having a first incidence plane and a second incidence plane; an emission plane; and a second concavity. The luminous flux control member satisfies the expression h1<h2+d×cot(θ1+θ2), where h1 is the space between the apex of the second concavity and a second imaginary line orthogonal to the center axis and that passes through the aperture edge portion, h2 is the space between the second imaginary line and the incidence position of light on the second incidence plane, d is the distance between the incidence position and the apex in the direction orthogonal to the center axis, θ1 is the angle of refraction of light in the incidence position, and θ2 is the angle of the tangent line at the incidence position in relation to the second imaginary line.

Claim (Index 1):
A light flux controlling member that controls a distribution of light emitted from a light-emitting element, the light flux controlling member comprising:\n an incidence surface that is an inner surface of a first recess, the first recess being disposed on a rear side of the light flux controlling member so as to intersect a central axis of the light flux controlling member, the incidence surface being configured to allow incidence of light emitted from the light-emitting element; an emission surface disposed on a front side of the light flux controlling member so as to intersect the central axis, the emission surface being configured to emit, to outside, light incident on the incidence surface; and a second recess disposed on the rear side so as to surround the incidence surface, wherein: the incidence surface includes a first incidence surface disposed so as to intersect the central axis, and a second incidence surface disposed so as to connect an outer edge of the first incidence surface and an opening edge of the first recess, in a cross section including the central axis, an intersection of the first incidence surface and the second incidence surface is disposed on the central axis side relative to the opening edge of the first recess, in the cross-section, an inclination angle of a tangent to an end portion of the second incidence surface on the first incidence surface side with respect to a first virtual line that is orthogonal to the central axis is smaller than an inclination angle of a tangent to an end portion of the first incidence surface on the second incidence surface side with respect to the first virtual line, and the light flux controlling member satisfies the following Expression (1):\n [Expression 1] \n h 1< h 2+ d \u00d7cot(\u03b81+\u03b82)\u2003\u2003(1) \n where: h1 represents a distance between an apex of the second recess and a second virtual line that is orthogonal to the central axis and passes through the opening edge of the first recess in the cross-section, h2 represents a distance between the second virtual line and an incident position of light which is emitted from the light-emitting element and is incident on the second incidence surface in the cross-section, d represents a distance between the incident position and the apex of the second recess in a direction orthogonal to the central axis in the cross-section, \u03b81 represents a refraction angle of the light incident on the incident position, and \u03b82 represents an inclination angle of a tangent to the incident position with respect to the second virtual line in the cross-section.
