PRINTED CIRCUIT BOARD, LIGHT EMITTING MODULE HAVING THE SAME, LIGHTING UNIT HAVING THE LIGHT EMITTING UNIT AND METHOD OF MANUFACTURING THE LIGHT EMITTING MUDULE

摘要

PURPOSE: A printed circuit board, a light emitting module with the printed circuit board, a light unit with the light emitting module, and a method of manufacturing the light emitting module are provided to make a light source to directly contact a heat emitting board, thereby increasing heat emitting performance. CONSTITUTION: A metal copper foil laminate plate(110) is formed by laminating an insulating layer(113) and a resin coating copper foil(112) on a heat emitting board. The metal copper foil laminate plate includes at least one groove. A portion of the resin coating copper foil is cut and the cut portion is mounted on the groove. The light source is bonded with the heat emitting board. The heat emitting board is made of copper.
