Abstract:
A headlight unit comprisingat least one low beam headlight including means for propagating a low beam,at least one high beam headlight including means for propagating a high beam,wherein said headlight unit is adapted for fulfilling at least two different sets of light intensity distribution requirements for the high beam;wherein a first set of light intensity distribution requirements for the high beam permit a first maximum light intensity in a center of the high beam not greater than 120 Lux and at least one first required light intensity in lateral regions of the high beam at about .+-.12.degree. of at least about 1.6 Lux in a horizontal center plane and of at least about 2.4 Lux at about 2.5.degree. under the horizontal center plane andwherein a second set of light intensity distribution requirements for the high beam permit a second maximum light intensity in the center of the high beam that is lower than the first maximum light intensity and from about 48 Lux to 240 Lux and at least one second required light intensity in lateral regions of the high beam extending further from the center of the high beam than the lateral regions illuminated according to the requirements of the first set of light intensity distribution requirements and of at least about 6 Lux at about .+-.5.15.degree. relative to a vertical center plane; andwherein the light intensities for fulfilling the second set of light intensity distribution requirements, at least in the lateral region on the opposing traffic side, are produced by the high beam issuing from the at least one high beam headlight and the second maximum light intensity according to the second set of light intensity distribution requirements is produced by the at least one high beam headlight.
