Patent ID: 8029170

Claim:
A light emitting diode (LED) lamp for alternating current (AC) power, the LED lamp comprising: at least one LED that operates in AC power; a metal printed circuit board (PCB) formed of an aluminum alloy, the PCB being an LED substrate for AC power on which said at least one LED operating in AC power is mounted; a main body with a built-in heatsink formed of aluminum, where a bottom of the LED substrate for the AC power adheres to an upper surface of a double-sided adhesive thermal conductive tape attached on an inner upper surface serving as a substrate base and formed of graphite, a reflection funnel having a reflection layer whose inner surface is entirely chrome-deposited extends from an upper end, a power connection hole passing through an inside, into which a power connection unit applying power to the LED substrate for the AC power is inserted is formed, and heatsink pins are formed in an entire outer peripheral surface; and a cap covering an opening of the reflection funnel of the main body with the built-in heatsink, wherein an entire side surface of the LED substrate is surrounded by the reflection funnel.
