Abstract: Each of a plurality of light emitting elements has a hexagonal shape with a center. An interior angle at each of corners is less than 180°. The plurality of light emitting elements include a first light emitting element having a first lateral side surface and a second light emitting element having a second lateral side surface. An orientation of the hexagonal shape of the second light emitting element is rotated by 30 degrees plus 30°+60°×N (N is an integer) with respect to the center of the second light emitting element relative to an orientation of the hexagonal shape of the first light emitting element such that the second lateral side surface is not parallel to the first lateral side surface.

Abstract: A light-emitting device includes a package and at least one light-emitting element. The package includes a concave portion which has a bottom surface. The bottom surface includes sides, package distances between opposite sides among the sides, a longest package distance among the package distances, a lower side among the sides, and an upper side among the sides opposite to the lower side. The at least one light-emitting element is arranged on the bottom surface of the concave portion and has a polygonal shape viewed along a front direction. The polygonal shape has light-emitting element distances between vertexes of the polygonal shape and has a longest light-emitting element distance among the light-emitting element distances. The at least one light-emitting element is arranged such that a light-emitting element lateral line along the longest light-emitting element distance is substantially parallel to a package lateral line along the longest package distance.

Abstract: Each of a plurality of light emitting elements has a polygonal shape with five or more corners. An interior angle at each of the corners is less than 180°. The plurality of light emitting elements include a first light emitting element having a first bottom surface, a first top surface opposite to the first bottom surface, and a first lateral side surface between the first bottom surface and the first top surface. The second light emitting element has a second bottom surface, a second top surface opposite to the second bottom surface, and a second lateral side surface between the second bottom surface and the second top surface. The second lateral side surface is provided not to oppose to the first lateral side surface in substantially parallel.
