1. the horizontal light and shade linear light in species stage type automobile short-distance headlamp, it is common single filament halogen tungsten bulb to be housed (such as H 7Bulb) special reflectors can realize that the brightness value of ladder light type and key point (such as the point of the 75R in the icon) significantly improves, and this special reflectors includes design considerations (the focal length F of focal axis horizontal plane top Base) identical left main surface (face 3. with face 4.) and right main surface (and face 3. '"'"' and face 4. '"'"'), in the station direction, with the downward shifts delta value of right main surface, the two has the corresponding discrepancy in elevation to lapping defect at the second quadrant, thereby realizes ladder light type;

  • 4. the face that correspondence is formed in the left main surface of right side top shade line makes " longitude and latitude " two-way confocal point (O that can both control light reflection direction and position 1Point) varifocal (F α

    4) face, impact point position (such as the 75R point) illumination is significantly promoted.
