An adaptive headlamp device includes a light emitting unit capable of emitting light rays, and a lens located in front of the light emitting unit. The lens includes an light-emergent surface that is located at a front end thereof, a rear end that defines a light-incident opening, a light-incident surface that defines a light-incident space facing the light emitting unit and communicating with the light-incident opening, and a light-reflecting surface that surrounds the light-incident surface. The light-reflecting surface includes first and second surface portions respectively located at upper and lower sides of the light-incident surface, third and fourth surface portions respectively located at left and right sides of the light-incident surface, and a plurality of interconnecting surface portions. Each interconnecting surface portion interconnects two adjacent ones of the first, second, third, and fourth surface portions. Each of the first, second, third, and fourth surface portions is unsmooth.
