Antiglare headlamp particularly a rectangular reflector type headlamp for motor vehicles |
摘要 |
The reflection surface of a rectangular reflector for a lower beam headlamp is composed of four sectors delimited by transition lines. Two diametrically opposed left and right sectors (11, 12) form a part of a paraboloid projecting a hot light spot. The diametrically opposed upper and lower sectors (13, 14) are part of a paraboloid-ellipsoid defining a parabola in its vertical center section and an ellipsis in its horizontal center section. The latter sectors project a light spot having a broad light dispersion and an increased front field illumination. The reflected light beam corresponds substantially to a dimmed lower light beam to be projected on the road so that a light dispersing glass of the headlamp does not require any optical means for light beam adjustment.
