LED MODULE FOR LIGHTING HAVING ADVANCED RADIANT HEAT PERFORMANCE

摘要

PURPOSE: An LED module for illumination is provided to uniformly maintain the temperature of an LED by releasing heat transferred from a metal printed circuit board to outside through a heat radiation steel sheet. CONSTITUTION: An insulating layer(120) is arranged at the upper side of a metal printed circuit board(110). The insulating layer is a DLC(Diamond Like Carbon) coating layer having a hyaline component. The metal printed circuit board is composed of a magnesium material in which thermal conductivity is excellent. A circuit pattern(122) is formed on around a mounting hole(121). An LED cell(130) is installed is installed at the mounting hole. A heat radiation steel sheet(140) is arranged at the lower side of the metal printed circuit board. The heat radiation steel sheet releases heat transferred from the metal printed circuit board to outside.
