This study examines the thermofluids characteristics of a LED lighting device. It is found that the heat sources of the present LED lighting are from the PCB and from the LED itself. To effectively improve the overall performance of the LED device, it is suggested that these two heat sources should be dealt with separately. For efficient thermal management of the LED, it is recommended to use the insulators and separate sink. The former can effectively block the heat flow from the PCB to LED panel where the latter can maintain the temperatures of PCB and LED within tolerable limit.
