This study tests the characteristics of heat radiation by applying the pin-height variables to 30-W LEDfloodlights. The angle of the heat sink enables us to identify the characteristics of the heat radiation based onthe temperature distribution. The results of the study are as follows. When the heat sinks are set towards theground, the heat transfer decreases in speed only to expands the temperature distribution, which adverselyaffects the characteristics of heat radiation and expands the temperature distribution of PCB with the LEDchip. We verify that the characteristics of heat radiation are adversely affected when the height of the coolingpin decreases and the heat radiation area decreases, which impedes the heat transfer and increases thetemperature distribution on the heat sink.
