Abstract

Official abstract text for this publication.

A light flux controlling member has: a light control/emission surface that controls a traveling direction of light; a concavity that allows a main beam to be incident inside; and a back surface that extends in a radial direction from an opening rim part of the concavity and that allows sub-beams to be incident inside. One of a grid convex part which arranges a plurality of strips of convex parts in a grid pattern and a grid concave part which arranges a plurality of strips of concave parts in a grid pattern is formed in the back surface of the light flux controlling member.

First claim

Opening claim text (preview).

The invention claimed is: 1. A light flux controlling member that controls light emitted from a light emitting element, the light flux controlling member comprising: a light control/emission surface that controls a traveling direction of the light emitted from the light emitting element; a concavity that allows a main beam to be incident inside, the main beam being light emitted in a predetermined range of an angle from a reference optical axis serving as a center axis of three-…
