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.
