[0023] By fixing the LED chip automobile lamp 4 on the heat sink 1, since the upper surface of the heat sink 1 is connected with a ring-shaped aluminum heat sink 2, and the aluminum heat sink 2 is connected to the bearing cavity of the heat sink 1 in a ring shape in sequence, and there is a gap between each aluminum heat sink 2, the air can be cooled back and forth in the multiple aluminum heat sinks 2, so that the connection of the aluminum heat sink 2 group can fully utilize the limited space of the automobile lamp assembly and improve the heat dissipation performance.
