Abstract:
1. A projector-type vehicle headlamp system, comprising: a light source, emitting the light rays; a multi-ellipsoid reflector, reflecting the light rays emitted from the light source and the multi-ellipsoid reflector is designed with a multi-ellipsoid equation (1); a lens, refracting the light rays emitted from the light source; wherein a variable sign “X” indicates a x-coordinate on the x-axis as a horizontal axis: a variable sign “Y” indicates a y-coordinate on the y-axis as a vertical axis; a variable sign “Z” indicates a z-coordinate on the z-axis as an optical axis; a function “a (θ,Z)” is a length equation (2) of the semi-major axis and a function “b(θ,Z)” is a length equation (3) of the semi-minor axis.
