LIGHT-EMITTING DEVICE

To provide a light-emitting device capable of homogenizing the illuminance of an irradiation region.SOLUTION: A light-emitting device is to form an irradiation region near an outer side of an opening, and includes a rectangular substrate, a light-emitting element disposed on the substrate, a reflection frame surrounding the light-emitting element with a pair of first reflection surfaces extending in a long-side direction of the substrate and facing each other with the light-emitting element disposed therebetween and a pair of second reflection surfaces extending in a short-side direction of the substrate and facing each other with the light-emitting element disposed therebetween and forming an outer edge of the opening for emitting the light from the light-emitting element to the outside, and a protrusion part protruding from each first reflection surface to the center of the light-emitting element. The first reflection surface is inclined to expand from the substrate to the opening and has a convex curved surface on the substrate side.SELECTED DRAWING: Figure 1 【課題】照射領域の照度を均一化させることを可能とする発光装置を提供する。【解決手段】発光装置は、開口部の外側近傍に照射領域を形成するための発光装置であって、長方形の基板と、基板に配置された発光素子と、基板の長手方向に延伸して発光素子を挟んで対向する一対の第１反射面、および基板の短手方向に延伸して発光素子を挟んで対向する一対の第２反射面により発光素子を囲み、かつ、発光素子からの光を外部に出射する開口部の外縁を形成する反射枠と、第１反射面から発光素子の中央に向かって突出する突出部と、を有し、第１反射面は、基板から開口部に向かって広がるように傾斜し、かつ、基板の側に凸の曲面を有する。【選択図】図１
