Claim 5:
6. The adaptive headlamp device as claimed in claim 2, wherein the lens has a central axis, and defines an imaginary parabola that has a imaginary focal point, imaginary focal point being spaced apart from the central axis in a radial direction of the lens perpendicular to the central axis, the light emitting unit including a light emitting source that is located in front of the imaginary focal point, some of the light rays that are emitted by the light emitting unit and that travel through the light-incident surface encountering the partition of the first surface portion of the light-reflecting surface and being defined as first light rays, extensions of the first light rays that are refracted by the light-incident surface intersecting at the imaginary focal point, the partition of the first surface portion having a front end point that is located between the imaginary parabola and the central axis in the radial direction, and a rear end point that is located at one side of the imaginary parabola opposite to the central axis in the radial direction.
