PROJECTION LAMP FOR VEHICLE HAVING STRUCTURE FOR ILLUMINATION OF CUT-OFF BOUNDARY AREA

摘要

The present invention relates to an illumination structure of a vehicle projection lamp, and more particularly to an illumination structure of a vehicle projection lamp having an improved structure for illuminating a cutoff boundary region with an appropriate amount of light required for low beam illumination. The lamp comprises a light source disposed at a first focal point of the reflector, a shield for low beam illumination disposed at a second focal point of the reflector, and an aspherical lens disposed away from the light source from the shield, wherein the shield comprises: a light source A left cutoff forming portion having a generally horizontal upper end portion such that light emitted from the light exits forwardly left and is illuminated with a generally horizontal left cutoff boundary below the optical axis; A right cutoff forming portion having an upper end of a predetermined inclination to be illuminated while having a right cutoff boundary gradually higher than the optical axis toward the front right side; And an elbow which is a boundary area between the left cutoff forming portion and the right cutoff forming portion, wherein the thickness of the left cutoff forming portion is formed thicker than the thickness of the right cutoff forming portion. Accordingly, a lighting structure that can satisfy a law that specifies a predetermined maximum brightness on the left side of the front of the vehicle and a predetermined minimum brightness on the right side of the vehicle may be provided.;Lamp, Cutoff, Illumination, Reflective Surface
