Description
上記課題を解決するために、本発明に係る発光デバイスは、基板と、前記基板上に配置された発光素子と、前記発光素子を覆う透光性の封止樹脂と、前記封止樹脂の表面から内部に向かって形成され、光線を散乱し前記発光素子からの光線に指向性を与える散乱構造であって、前記封止樹脂の表面からの深さが、前記発光素子の発光面の前記封止樹脂の表面からの深さよりも浅い散乱構造と、を有し、前記散乱構造は、平行に配置された複数本の溝（断面略Ｖ字状の凹溝を除く）、複数の円柱形状、円柱形状の相補形状及びハニカム形状の少なくともいずれかである。
In order to solve the above problems, a light emitting device according to the present invention includes a substrate, a light emitting element disposed on the substrate, a translucent sealing resin covering the light emitting element, and a surface of the sealing resin. The scattering structure is formed from the inside toward the inside and scatters light rays to give directivity to the light rays from the light emitting element, and the depth from the surface of the sealing resin is the sealing of the light emitting surface of the light emitting element. A scattering structure shallower than the depth from the surface of the stop resin, and the scattering structure includes a plurality of grooves arranged in parallel (excluding a groove having a substantially V-shaped cross section) , a plurality of cylindrical shapes, It is at least one of a cylindrical complementary shape and a honeycomb shape.
