In a heat dissipating apparatus for an automotive LED lamp, the automotive LED lamp includes an automotive lamp set, a heat dissipating module, a plurality of LEDs, and a reflecting unit. The heat dissipating module is wrapped to form an insulation circuit for separating heat energy and electric power of the insulation circuit and heat dissipating module. The LED is electrically connected to the insulation circuit, and a main base of the LED installs a metal conducting plate for conducting the heat produced by the LED to the heat dissipating module. The reflecting unit is installed in the automotive lamp set, so that the heat dissipating module can use a cold air or a liquid coolant as the heat dissipating medium for dissipating heat, preventing a drop of light output caused by an overheat, and avoiding damages to the LED to extend the life expectancy of the automotive LED lamp.
