High power LED lighting assembly incorporated with a heat dissipation module with heat pipe
First Claim
1. A LED lighting assembly, comprising:
- a heat exchange base, comprising at least one LED configuration plane and at least one central hollow part, the LED configuration plane thereof being located on an outer surface of the heat exchange base;
at least one LED array, comprising a plurality of LEDs, each LED being positioned on the LED configuration plane of the heat exchange base at a predetermined angle for projection;
at least one heat pipe, comprising a heated section, a cooling section and a conducting section which connects the heated section to the cooling section and containing a working fluid, in which the heated section is inserted into the central hollow part of the heat exchange base and the connecting channel extends from the heat exchange base; and
a heat dissipation module, being arranged at the cooling section of the heat pipe;
wherein when a thermal energy generated by the LED is conducted from the heat exchange base to the heated section of the heat pipe, the working fluid in the heat pipe is heated and flows from the conducting section to the cooling section and transmits heat to the heat dissipation module at the cooling section to dissipates the thermal energy.

Abstract
A high power light emitting diode (LED) lighting assembly incorporated with heat dissipation module is provided. The LED lighting assembly includes a heat exchange base, at least one LED array, at least one heat pipe and a heat dissipation module. The heat exchange base includes at least one LED configuration plan for mounting of the LED array and at least a hollow part for insertion of the heat pipe. The LED array is arranged at a predetermined projecting angle at the LED configuration plane. The heat pipe includes a heated section, a cooling section and a conducting section, and contains a working fluid therein. The heat exchange base is mounted to the heated section and the heat dissipation module is mounted to the cooling section. The thermal energy generated by the LEDs is conducted from the heat exchange base to the heated section of the heat pipe, whereby allowing the working fluid in the heat pipe to be heated and vaporized, and flows, from the conducting section to the cooling section for dissipation at the heat dissipation module.
