Claim Text:
1. A high energy invisible light light emitting diode (LED) having safety indication, comprising: a high energy invisible light light emitting structure, sequentially stacking and comprising a P-type semiconductor layer, a high energy invisible light light emitting layer that receives a forward bias to emit invisible light, and an N-type semiconductor layer, the N-type semiconductor layer comprising a light exiting surface away from the high energy invisible light light emitting layer; two potential applying layers, respectively being in contact with the P-type semiconductor layer and the N-type semiconductor layer; and a safety indication structure, deposed on the high energy invisible light light emitting structure, comprising a semiconductor layer contacting with the light exiting surface directly and a photoluminescent light emitting layer absorbing and converting invisible light to visible light and contacting with the semiconductor layer directly, wherein the photoluminescent light emitting layer comprises a plurality of hollow regions to reveal invisible light directly and forming a three-dimensional structure which is partially hollow on the light exiting surface, wherein the safety indication structure is disposed on a partial region of the light exiting surface, and wherein the safety indication structure is one of numeric, text, and text and numeric representations.
