[0002] In the existing automotive headlights, a glass lens 1 is assembled on a plastic-structured bracket 2, and a direct lighting panel 3 is assembled on another metal radiator 4 to achieve a certain heat conduction and heat dissipation effect, as shown in the attachment. Figure 1 In this assembly method, the plastic bracket 2 has a large volume ratio, while the metal radiator 4 has a small volume ratio. In this way, the direct lighting panel 3 works on the metal radiator 4 with a small volume, and a good heat dissipation effect cannot be achieved.

The front end of the metal heat dissipation housing is used to fix the direct lighting panel and the glass lens, and the rear end of the metal heat dissipation housing is used to be fixedly connected to the low beam heat dissipation housing of the low beam mechanism.

[0006] Further improvement: An annular mounting surface is arranged on the inner side of the front part of the metal heat dissipation housing, and the direct lighting panel is fixed on the annular mounting surface by bolts.
