LED lamp cooling apparatus with pulsating heat pipe

An LED lamp cooling apparatus comprising:

• a substrate;
• a plurality of LEDs mounted on the substrate;
• a pulsating heat pipe having a heat receiving portion in thermal connection with the LEDs and a heat radiation portion;
• and
• a heat sink in thermal connection with the heat radiation portion of the pulsating heat pipe;
• wherein the pulsating heat pipe has working fluid therein, the working fluid having alternate liquid and vapor segments, the fluid moving from the heat receiving portion to the heat releasing portion in a pulsating manner when the heat receiving portion receives heat from the LEDs;
• and
• wherein the LED lamp cooling apparatus further comprises a reflector for reflecting light generated by the LEDs to a specific spot.
