LIGHT-EMITTING DIODE AND LIGHT-EMITTING APPARATUS

The present invention relates to the technical field of light-emitting diode chips, and in particular to a light-emitting diode and a light-emitting apparatus. The light-emitting diode comprises: a semiconductor layer sequence, the semiconductor layer sequence sequentially comprising a first semiconductor layer, a light-emitting layer and a second semiconductor layer from bottom to top; and a first electrode and a second electrode, the first electrode or the second electrode having an electrode structure, the electrode structure comprising a first metal layer, a second metal layer and a third metal layer, the first metal layer being electrically connected to a second semiconductor layer sequence, the second metal layer being provided on the first metal layer, the third metal layer being provided on the second metal layer, and the second metal layer containing a nickel-phosphorus alloy or a nickel-phosphorus compound. Compared with the prior art, by means of the design of adding the second metal layer, the pre
