Thermal characteristics of 20 W LED module on light thermal conductive plastic (TCP) heat sink were investigated in comparison with that on aluminum die casting alloy (ADC-12). Thermal simulations of the heat sinks were conducted by using flow simulation of SolidWorks with the following input parameters: density is 1.70 and $2.82kg/m^2$, thermal conductivity is 20 and $92W/(m{\cdot}K)$ for TCP and ADC-12, respectively. The simulated and measured temperatures of the LED modules on TCP heat sink were consistent with its measured temperature, which was $3^{\circ}C$ higher that on ADC-12. The fabricated LED module on TCP heat sink with a weight of 120.5 g was 30% lighter in weight than that of the ADC-12 reference with 171.0 g.
