Claim Text:
1. An LED lighting module comprising: a substrate; a (+) slug layer and a (−) slug layer formed on the substrate and spaced apart from each other at regular intervals; and at least one LED chip formed on the (+) slug layer or the (−) slug layer to have p-type and n-type electrodes, wherein the (+) slug layer and the (−) slug layer each include an electrode layer formed on the substrate and a reflection layer covering the electrode layer, and the LED chip is formed on the reflection layer, and wherein the substrate includes a metal layer and a ceramic layer formed on the metal layer, and the ceramic layer is mixed with at least one of aluminum nitrides (AlN) and aluminum oxides (AlOx), and wherein when the LED lighting module is less than 50 W class, aluminum oxide (AlOx) powder included in a content of 40 to 80 wt % and aluminum nitride (AlN) powder included in a content of 20 to 60 wt % on the basis of the total weight of the ceramic layer, when the LED lighting module is in the 50 to 100 W class, aluminum oxide (AlOx) powder included in a content of 15 to 50 wt % and aluminum nitride (AlN) powder included in a content of 50 to 85 wt % on the basis of the total weight of the ceramic layer, and when the LED lighting module is greater than 100 W or more class, aluminum oxide (AlOx) powder included in a content of 0 to 30 wt % and aluminum nitride (AlN) powder included in a content of 70 to 100 wt % on the basis of the total weight of the ceramic layer.
