An innovative indoor LED lighting prototype that uses pressed-flat grooved heat pipes as heat transfer channels to conduct LED-released heat to heat-sink-fins is proposed. Natural convection inside the flow channels within the heat-sink fins serves as the main heat dissipation mechanism. In order to accommodate different illumination directions, the thermal performance of the LED lighting prototype at different inclination and rotation angles (different heat pipe performances) were experimentally investigated. The results show that the temperature distribution of the prototypes is dependent on inclination angles, however, independent of rotation angles. FFT analysis reveals that dominant fluctuation frequencies of the temperature around the central area of the prototype with different inclination angles are about 4.7 minutes.
