Abstract
A vehicle lamp has a lamp holder, an LED array, an interior heat sink and a heat exchanger. The lamp holder is hollow and has a heat conductive portion. The LED array is mounted in the lamp holder. The interior heat sink is mounted on the LED array and has an inner conductor attached between the LED array and the heat conductive portion. The heat exchanger is mounted on an outer side of the heat conductive portion. Therefore, the vehicle lamp can efficiently dissipate heat generated by the LED array by the interior heat sink and the heat exchanger with little or no dust entering the lamp holder and accumulating on the LED array for improved lifespan and constant heat dissipating performance.
