A light emitting diode (LED) array package structure includes a package substrate, a LED array, a high thermal conductive color conversion layer and a transparent ceramic substrate. The high thermal conductive color conversion layer includes a mixture of transparent optical resin, phosphor powder and transparent ceramic filler, and is directly dispensed on the LED array. The transparent ceramic substrate contacts directly the high thermal conductive color conversion layer. A portion of the transparent ceramic filler contacts the package substrate while another portion contacts the transparent ceramic substrate. The conduction and radiation heat generated by the high thermal conductive color conversion layer, and the conductive heating caused by the LED chips, both can be removed through either the package substrate or the transparent ceramic substrate, thereby improving the white light output power and being suitable for implementing with polymeric optical components to reduce glare and enhance luminous efficiency.
