Heat sink and LED illuminating apparatus comprising the same

摘要

A light emitting diode (LED) illuminating apparatus including a heat sink, a light emitting module, a power connection portion, a translucent cover and a wiring path. The heat sink has a plurality of heat dissipation fins. The light emitting module is positioned on an upper portion of the heat sink. The power connection portion is positioned below a lower portion of the heat sink. The translucent cover is mounted to cover an upper portion of the light emitting module. The wiring path is formed in the heat sink so as to accommodate a wire for electrically connecting the power connection portion and the light emitting module. In the LED illuminating apparatus, the light emitting module emits light by directly receiving AC power supplied through the wire accommodated in the wiring path.
