The present invention relates to a light-emitting diode (LED) structure, which comprises an LED unit. The LED unit is doped with a plurality of fluorescent powders in at least an arbitrary layer on one side of a light-emitting layer. Alternatively, the LED unit includes a plurality of fluorescent powder particles arranged on at least a light-emitting surface of the LED unit. No gel is adopted for disposing or packaging fluorescent powders. Thereby, gel yellowing caused by long-term high-temperature heating of the LED structure will not occur. The yellowing phenomenon will affect the light-emitting efficiency of LED and induce color deviation.
