PURPOSE: A heat sink for an LED(Light Emitting Diode) lamp is provided to improve illuminance and performance of an LED lamp by discharging the heat from the LED lamp. CONSTITUTION: A fluid space(112) is formed in a lower part of a housing(110). A cover plate(140) is fixed and coupled in the lower part of the housing in order to seal the fluid space. A plurality of heat pipes(120) are formed in an upper part of the housing to be connected to the fluid space. The plurality of grooves are vertically formed in an inner surface of the heat pipe. An inlet port is formed in one of the plurality of heat pipes. A plurality of heat radiation fins are formed in the outer circumference of the heat pipe. A spring wick(130) is inserted into the heat pipe. The operation fluid is filled in the fluid tube. |
