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 7):
