LIGHT-EMITTING MODULE AND LUMINAIRE

PROBLEM TO BE SOLVED: To acquire a light-emitting module which has a simple structure capable of efficiently utilizing the light emitted from side surfaces of light-emitting elements.SOLUTION: A light-emitting module emits light toward an irradiated body and includes: a light-emitting substrate on which a plurality of pieces of light-emitting elements are mounted; and a light guide substrate which is formed by a material having light transmissivity, in which openings are formed at positions corresponding to the plurality of light-emitting elements respectively, and which is overlapped with the light-emitting substrate in a state where the light-emitting elements are stored in the openings. The light guide substrate has: a first inverted triangle part protruding toward the light-emitting substrate at a lateral side of at least one light-emitting element out of the plurality of light-emitting elements; and a light emission surface opposing to the irradiated body. The first inverted triangle part includes: a first inclined surface for refracting the light emitted by the light-emitting elements; and a second inclined surface for totally reflecting the light refracted at the first inclined surface toward the light emission surface.SELECTED DRAWING: Figure 3 【課題】発光素子の側面から発せられた光を効率良く利用することができるシンプルな構成の発光モジュールを得る。【解決手段】発光モジュールは、被照射体に向けて光を発する発光モジュールであって、複数個の発光素子が実装された発光基板と、透光性を有する材質で形成され、複数個の発光素子のそれぞれと対応した位置に開口部が形成され、該開口部に発光素子を収容させた状態で発光基板と重ねられた導光基板と、を備え、導光基板は、複数個の発光素子のうちの少なくとも１個の発光素子の側方で、発光基板に向かって突出する第１逆三角形部と、被照射体と対向する光出射面と、を有し、第１逆三角形部は、発光素子が発した光を屈折させる第１傾斜面と、第１傾斜面で屈折された光を光出射面に向けて全反射させる第２傾斜面と、を含むものである。【選択図】図３
