Abstract: A light flux control member has a back face provided with a recess and a ring-like-recess-portion surrounding the recess. Output light of a point-like-light-source (light emission element) is incident to the recess and the ring-like-recess-portion. Incident light to the recess is emitted from a light control emission face after inner-propagation. Incident light to the ring-like-recess-portion is refracted as to hardly generate inner-propagation light deflected to directions near to a direction of reference optical axis L, resulting in outgoing from any part of the light control emission face, or, if some outgoing occurs from the light control emission face, such outgoing occurs only at an outer periphery portion of the light control emission face. As a result, illumination light quality is avoided from being reduced by appearance of conspicuous ring-like bright part. In addition, uniform illumination light can be supplied to a broad angle range.

Abstract: An optical emitting module includes a light-emitting device that emits light, and a lens member having a refracting surface configured to refract light emitted from the light-emitting device and to emit refracted light. The lens member is configured such that, when the angle of a light beam emitted from the lens member with respect to a principal light axis is ?1, a light beam with the maximum emission angle ?1 from the lens member is emitted from the refracting surface in the vicinity of a point where the refracting surface and the principal light axis cross each other. With this configuration, even when the light-emitting surface of a light source is large, it is possible to suppress the spread of emergent light from the lens member, obtaining a light intensity distribution with high uniformity.
