Abstract

The demand for the high Lumens output on the commercialized Light-emitting diode, LED bulb has resulted in the increase of operating power and generation of heat. A study on the thermal performance of commercialized LED bulbs was done by using Elmer finite element simulation method. The variation approach was limited to input power (2 Watt- 10 Watt) and the heat performance was compared. The result gives a comparison of the variation of the model and the heat distribution. Analysis showed that the input power and bulb geometry give direct effect on the junction temperature.
