Finite element modelling of thermal performance of LED lamp using open source software - salome and elmer

Light emitting diodes (LEDs) has presented its outstanding performance compared to other present lighting sources such as fluorescent and incandescent. Thus, LEDs has become the favourable lighting source in this decade. However, the heat generated from the LEDs has limited its overall performances. This paper has demonstrated the use of simulation technique to access the thermal performance of the LED lamp. The modelling and simulation was performed using the open source software - Salome and Elmer. The thermal simulation was conducted by considering LED chip, metal core printed circuit board (MCPCB) and heat sink. After achieving the grid independence, the result from the simulation model shows the highest temperature of 131.928°C on the LEDs and the lowest temperature of 126.974°C for the heat sink.
