In order to achieve the purpose, the utility model adopts the technical scheme that: an LED automobile headlamp provided with a thin D4S converter comprises a body device, a D4S converter and a power line for connecting the two; the D4S converter comprises a drive PCB board, a shell for placing the drive PCB board; the driving PCB comprises a first PCB, a second PCB and two connecting wires for electrically connecting the first PCB and the second PCB; the shell comprises a first cavity and a second cavity which are used for placing a first PCB and a second PCB respectively.

Preferably, the thickness of the first PCB and the second PCB is 0.8mm, only one surface of the first PCB and the second PCB is provided with an electronic component, and the electronic components are all patch components.

Preferably, a connecting plate integrally formed with the first cavity and the second cavity is arranged between the first cavity and the second cavity, and a transverse groove for two connecting lines to pass through is formed in the connecting plate.

Preferably, the second PCB is circular, and a cylindrical insertion part is provided on a bottom surface thereof; and a cylindrical accommodating part for accommodating the cylindrical insertion part is arranged in the second cavity.

The beneficial technical effects are as follows: the driving PCB adopted by the D4S converter is divided into two parts, namely a first PCB and a second PCB, wherein the thicknesses of the first PCB and the second PCB are small and are only 0.8 mm; only one side of the electronic element and the single side of the electronic element are provided with the electronic elements which are all patch elements, so that the overall thickness of the electronic element and the single side of the electronic element can be reduced; meanwhile, the first PCB and the second PCB are respectively arranged in the first cavity and the second cavity instead of being stacked together, so that the thickness of the shell is reduced, and the heat dissipation of the first PCB and the second PCB is facilitated; therefore, compared with the D4SLED converter in the prior art, the D4S converter is small in thickness, convenient to adapt to more vehicle models and wide in application range.
