The invention relates to an automobile headlight, in particular to an air cooling type energy-saving automobile headlight which comprises a light source containing cavity defined by a shell and light-transmitting windshield, a light-transmitting hood, an inner column, a power introducing head, a light-emitting body and an actuator. The light-transmitting hood, the inner column, the power introducing head, the light-emitting body and the actuator are arranged in the light source containing cavity. The light-emitting body is an LED, the light-transmitting windshield is provided with an air inlet, an air outlet is formed in the shell, and the light-transmitting hood and the inner column define an air cavity. The light-emitting body is suspended in the air cavity through the inner column, the outer end of the inner column is fixedly connected to the power introducing head, and the power introducing head is electrically connected with the actuator. The power introducing head is detachably connected with the shell, the air cavity is filled with cooling air, and the air pressure in the air cavity is larger than one standard atmospheric pressure. The air cooling type energy-saving automobile headlight has the advantages that the cooling effect is good, cooling is even, the LED is used as a light source, and the problem that the LED can not be used as the light source due to the fact that an existing automobile headlight is poor in cooling effect is solved.
