Basically concentrate the beam: To reduce the beam width (to near parallel) so the intensity at a larger distnace from the headlight is higher.
Explanation:
Work out the light ray diagram if an object is at the focus of a concave mirror.
You will find the rays are parallel as the exit the mirror, so the light beam is parallel and all the light generated from the lamp is focussed.
