PRINTED CIRCUIT BOARD FOR MOUNTING LIGHT EMITTING DIODE PACKAGE

摘要

PURPOSE: A printed circuit board for mounting a light emitting diode is provided to efficiently discharge heat from the light emitting diode by combining a heat radiation pad with the rear of a substrate. CONSTITUTION: A substrate(110) has a conductive pattern for mounting and driving a light emitting diode. A first heat radiation pad(114) and a second heat radiation pad are formed with the same circular type as the substrate. An insulation pattern(118) electrically insulates the conductive pattern and the first heat radiation pad. A bonding pad(130) makes a pair around a mounting point(134). A via hole(112) transmits heat from the light emitting diode to the second heat radiation pad attached to the rear of the substrate.
