SURFACE MOUNT TYPE LIGHT-EMITTING DIODE LAMP LARGE-CURRENT AND HIGH EFFICIENCY AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting diode lamp that has a chip mounted on a circuit board and can be driven with a large current.

SOLUTION: The light-emitting diode lamp comprises: the circuit board; a light-emitting diode chip integrated on a thermal conductive metal electrode layer on the circuit board for packaging; a light extraction section molded on the light-emitting diode chip; and a heat emission section composed of at least one of an exposure structure for heat emission, where at least one portion of the bottom surface of the electrode layer to which the light-emitting diode chip is packaged is exposed, and a pole structure for heat emission having a through hole for nearly passing through the electrode layer vertically.
