Abstract
A light emitting diode (LED) illumination apparatus including an illumination module, a heat dissipating unit and a loop heat pipe (LHP) device is provided. The illumination module includes a base and many LEDs. The LEDs are disposed on the base. The LHP device contains working fluid and includes an evaporator, a condenser, a first transmitting pipe and a second transmitting pipe. The evaporator is associated with the base and has an outlet, an inlet and a chamber. The condenser is conformably associated with the heat dissipating unit. The condenser has an inlet and an outlet, wherein at least one part of the condenser stretches in a curved pipe shape along a surface of the heat dissipating unit. The first transmitting pipe communicates the evaporator outlet to the condenser inlet. The second transmitting pipe communicates the condenser outlet to the evaporator inlet.
