PURPOSE: An LED lighting module is provided to extend the life time of a lighting module by increasing heat radiation efficiency of a heat sink by comprising a first heat radiating unit composed of a protective layer at the heat sink and a second heat radiating unit composed of a heat radiating pin. CONSTITUTION: A light emitting unit(110) comprises at least one LED chip(111). A heat sink(120) emits heat generated in a radiation process of the light emitting unit to the outside. The heat sink comprises a first radiating unit(120a) and a second radiating unit(120b). The first radiating unit comprises at least one heat radiating pin(125) extended from a body of the heat sink. The second radiating unit comprises a first metal layer(121), an insulating layer(122), and a protective layer(124) including a second metal layer(123).
