Abstract：In order to improve the thermal performance of LED lamps used in tunnel , a radiator with circular heat sink has been designed .The finite element software ANSYS is applied to simulate and analysis the thermal performance of LED lamp and optimize the radiator .The experimental results shown that the simulation analysis is accurate and credible .And it was observed that the cooling capacity of heat sink increases with increasing of the height of fins and the number of fins , but this trend has slowed down when the variation reaches a certain value , and the cooling capacity of heat sink increases with increasing of the thickness of fins, but the trend inversed when the thickness of fins reached 4mm.The analysis results could provide valuable reference for the radiator design .
