The invention relates to an LED (Light Emitting Diode) package structure capable of improving the illumination with a softened lighting effect. The LED package structure comprises a base plate, wherein the base plate is provided with a plurality of LED luminous chips; the LED luminous chips are provided with a heat-conduction-reinforced light emission part and are positioned at the bottom of interior of the heat-conduction-reinforced light emission part; and the heat-conduction-reinforced light emission part is provided with an illumination softening part which is pressed and covered by a first lens. According to the invention, heat conduction is carried out to an LED array and the emission of the light rays is improved both through the heat-conduction-reinforced light emission part; the light rays of the LED array are softened by the illumination softening part, so that the dazzling degree is reduced; a chip array of multiple LEDs is formed on the surface of the base plate, a lens array is formed by lenses corresponding to the arrangement of the chips, finally a package cavity is sealed, and the light emission efficiency is improved after the light rays pass through the first lens and a second lens; and the first lens is pressed and covered by a precise beam splitting lens, thus a precise beam splitting effect is achieved. The LED package structure has the advantages of simple and compact structure, convenience in installation and use, uniform emergent light color, high light emission efficiency, lowered use cost and wide application range.
