The invention relates to the technical field of light emitting diodes, in particular to a light emitting diode package structure. The light emitting diode package structure includes a crystal of a light emitting diode and further comprises a base, a fixing ring, a heat dissipating assembly, a heat dissipating wire, a lens and a transparent frame. The light emitting diode package structure is provided with the heat dissipating assembly, the fixing ring and the heat dissipating wire, heat generated by working of the light emitting diode is transmitted to the heat dissipating wire through the fixing ring, then the heat is transmitted to the heat dissipating assembly through the heat dissipating wire to realize timely heat dissipation of the crystal, and therefore the influence on the stimulating effect of phosphor powder coated on the crystal is avoided; the heat dissipating assembly consists of a clamping ring, heat dissipating fins and a connecting ring assembly, and the heat can be quickly dissipated through the heat dissipating fins; the lens is arranged, so that a light source emitted by the light emitting diode can be diffused through the lens to maximize the light emitting range; and meanwhile, hemispherical setting allows for uniform distribution of light throughout the lens, and uneven illumination range is avoided.
