发明名称 Light-emitting diode with high lighting efficiency
摘要 The invention discloses a light-emitting diode, including a substrate, a first conductive type semiconductor layer, a second conductive type semiconductor layer, a light-emitting layer and plural laminated structures. The first conductive type semiconductor layer, the light-emitting layer and the second conductive type semiconductor layer are formed on the substrate in sequence. The plural laminated structures are formed on the upper surface of the second conductive type semiconductor layer such that the upper surface is partially exposed. Each laminated structure consists of at least one first insulated layer with a high refractive index and at least one second insulated layer with a low refractive index, where the at least one first insulated layer and the at least one second insulated layer are alternately formed to obtain said each laminated structure. Thereby, light emitted from the light-emitting layer can be reflected by the laminated structures to enhance the light-extraction efficiency.
