A light-emitting diode component, which comprises a semiconductor sequence, one side of the semiconductor sequence being a light exiting surface, the other side comprising a semiconductor current spreading layer, the semiconductor sequence comprising a first electrically-conductive semiconductor layer, an active layer, and a second electrically-conductive semiconductor layer, and characterized in that: the current spreading layer is a doped electrically-conductive semiconductor layer, a part of the side of the current spreading layer away from the light exiting surface is provided with a recess, a transparent insulating layer is provided in the recess, and a reflective layer is provided on the other side of the transparent insulating layer and on the non-recessed part of the current spreading layer. With the part of the current spreading layer being provided with the recess, the transparent insulating layer filled in the recess, and the reflective layer provided on the transparent insulating layer and on the
