  • Publication number: 20230317880
    Abstract: A light-emitting element includes a semiconductor structure, which has a long side extending in a first direction and a short side extending in a second direction orthogonal to the first direction and being shorter than the long side in a top view and includes an n-layer, a p-layer, and an active layer. The n-layer includes a plurality of first regions exposed from the active layer and the p-layer, and a second region above which the active layer and the p-layer are disposed. The light-emitting element further includes a plurality of n-external connection portions, each disposed above the second region and each electrically connected to the n-electrode, and a plurality of p-external connection portions, each disposed on the p-electrode and electrically connected to the p-electrode. In a top view, the first region is disposed between the plurality of n-external connection portions and the plurality of p-external connection portions.

  • Patent number: 9041039
    Abstract: A semiconductor light emitting element includes: an insulating substrate having a plurality of convex portions on a surface thereof; a plurality of light emitting element components having semiconductor laminated bodies that are laminated on the insulating substrate and are separated from one another by a groove that exposes the convex portions; and a connector connecting between the light emitting element components. The light emitting element components include a first light emitting element component and a second light emitting element component. The first light emitting element component is separated from the second light emitting element component with the groove in between, and has a first protrusion that protrudes toward the second light emitting element component. The connector includes a first connector having a shape that straddles the groove and that follows the convex portions, and has a straight section.
