Abstract: A light emitting device is provided which includes a printed board, light emitting elements, and a light-transmissive member. The light emitting elements are arranged in three or more rows, and mounted on the printed board. The light-transmissive member includes three or more semi-semi-cylindrical lens portions that are arranged side by side transversely to cover the three or more rows. The heights of the tops of the semi-cylindrical lens portions are substantially equal to each other. The semi-cylindrical lens portions include first semi-cylindrical lens portions which are arranged to cover at least the both end rows, and a second semi-cylindrical lens portion which is arranged on the interior sides relative to the first semi-cylindrical lens portions in the transverse direction. The radius of curvature of the second semi-cylindrical lens portion is smaller than the first semi-cylindrical lens portions.

Abstract: A light emitting device includes light emitting elements. A substrate includes electrically conductive layers each having a first region in which the light emitting elements are arranged and a second region connected to the first region and provided at a position higher than the first region. An electrically conductive wire electrically connects the light emitting elements arranged on the electrically conductive layer and the second region of the adjacent electrically conductive layer. A resin molded portion is formed of a light-transmissive resin that seals the light emitting elements and the electrically conductive wire. The resin molded portion has a shape in which centrally projected cylindrical lens portions is aligned, and in each of the cylindrical lens portions, the light emitting elements is arranged in a line shape. The second region is arranged between the light emitting elements in the light emitting element array.

Abstract: A light emitting device includes a substrate, a plurality of light emitting elements arranged in three or more rows on the substrate, and a light-transmissive member including a cylindrical lens portion having an array of three or more cylindrical lenses arranged parallel to each other along the rows of the light emitting elements so that each of the cylindrical lenses is on one of the three or more rows of light emitting elements. The rows of the light emitting elements are arranged with substantially uniform intervals. The cylindrical lens portion includes first cylindrical lens portions including at least cylindrical lenses at outermost sides of the array, and a second cylindrical lens portion arranged at an inner side of the first cylindrical lens portions and having a height greatest in the cylindrical lens portion.

Abstract: Disclosed is a substrate for mounting light emitting element with a high positional accuracy and a method of fixing the substrate. A substrate for mounting light emitting element defines a first recess and a second recess in first side in a plan view. The first recess is defined by two corner portions and a straight portion which connects the two corner portions, and the second recess further includes at least two straight portions each narrowing toward the inner end portion.
