PURPOSE: A LED lighting module is provided to effectively releasing heat coming from a LED chip by arranging LED heat sink between a metal PCB and LED package. CONSTITUTION: A LED heat sink(230) releases heat coming from a LED chip(226). A LED package(220) composed of a lead frame(222), lead line(224), and cover(228) is located on the top of the LED heat sink. A metal PCB(210) composed of a metal plate(212), insulating layer(214), and circuit pattern(216) is located on the lower part of the LED heat sink and releases heat of the LED heat sink.
