ABSTRACT:
A vehicle headlamp reflector comprises a dished body having a generally rectangular front opening and a bulb-receiving rear opening. The body is internally reflective and includes a first pair of laterally disposed reflective portions, a second pair of laterally disposed reflective portions, an upper reflective portion and a lower reflective portion. The portions are disposed inwardly of the respective portions, are on opposite sides of the opening and between the portions. The portions lie on the same paraboloidal surface while the portions lie on a different paraboloidal surface. The two paraboloid surfaces have common axes and common foci but the focal length of the paraboloidal surface in respect of the portions is less than the other paraboloidal surface.
