1. A high-beam lighting device, applied to a left vehicle lamp and a right vehicle lamp, wherein the high-beam lighting device comprises: a main high-beam module and an auxiliary high-beam module, the main high-beam module comprises a primary optical structure, and the primary optical structure enables the main high-beam module to form a main high-beam light shape with a light and shade cut-off line; the auxiliary high-beam module forms an auxiliary high-beam light shape adjustable in widening angle; and the main high-beam light shape is overlapped with the auxiliary high-beam light shape to form a high-beam light shape with the light and shade cut-off line and adjustable in light shape widening angle;
the primary optical structure comprises: a reflection unit and a shading structure located in front of the reflection unit, the shading structure blocks part of reflected light from the reflection unit, and the primary optical structure is configured to be one of the following two structures:
where the primary optical structure is for use in the left vehicle lamp, the shading structure is arranged at the left side portion of an optical axis in front of the reflection unit, and the reflected light blocked by the shading structure and the reflected light that is not blocked are bound by a right side edge and an upper side edge of the shading structure, to make, and locate, the light and shade cut-off line on the right side of the main high-beam light shape; and
where the primary optical structure is for use in the right vehicle lamp, the shading structure is arranged at the right side portion of the optical axis in front of the reflection unit, and the reflected light blocked by the shading structure and the reflected light that is not blocked are bound by a left side edge and the upper side edge of the shading structure, to make, and locate, the light and shade cut-off line on the left side of the main high-beam light shape.
