ABSTRACT:
A vehicle headlamp is provided including a parabolic reflector, a high intensity discharge bulb mounted with the reflector having a main arc located generally at a focal point, and a lens for focusing the bulb having a vertical and a horizontal axis intersecting the reflector axis. The reflector has a maximum horizontal dimension W made up of a left width WL and a right width WR. There is a two-part zone 1 bordered on the bottom by the horizontal axis of the lens and bordered on the top by the top of the lens as long as the top of the lens is 60 millimeters or less from the horizontal axis. The zone 1 is bordered on the right side by a line extending a distance RT from the vertical axis going down to a distance RB taken from the vertical axis, and RT equals 1/4 WR and RB equals 3/4 WR. In like manner, the left side of zone 1 is bordered on the top at a distance LT from the vertical axis and a distance LB along the horizontal axis from the vertical axis, and LT equals 1/4 WL and LB equals 3/4 WL. The lens projects a hot spot test point one (0.5 d, 1.5 r) and at a hot spot test point two (1.5 d, 2 r) approximating at least 90 percent of the light at test point one and at least 70 percent of the light at point two from zone 1.
