Abstract	A finite element method based on a direct algorithm is applied in this study to estimate the time-dependent and time-independent convection heat transfer of high-bright LED(HB LED) heat dissipating mechanisms. Numerically simulation and experimental measurement are both performed to investigate the thermal characteristics of HB LED devices. By monitoring the transient temperatures at the different measurement positions of the device, it is placed into well controlling ambient temperature environment when the LED is subjected to different thermal loading. Experimental data is subjected to the numerical tests in order to verify the accuracy of simulation models. Therefore, the thermal management of HB LED devices can be investigated. The results indicate that established models are not only proved to enhance heat dissipating of LED but also well consistency to the experimental data. Finally, a simple design of HB LED device is demonstrated to prove the success of this research and can it be applied in the present industry.
