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

摘要

The present invention relates to light projection lamp structure for a vehicle, the low beam to the appropriate amount of light required during illumination relates to the cut-off boundary region to the illumination structure for a vehicle having an improved structure for a projection lamp for illuminating. The lamp includes a light source disposed on a first focus of the reflector, with the reflector shield for low beam illuminated on the second focal point of the arrangement, and includes an aspherical lens disposed on the side far from the light source and the shield, wherein the shield comprises: a light source light is emitted from, have a substantially horizontal cut-off boundary to the left below the optical axis while the front left and the left cut-off forming portion having a generally horizontal upper end such that lights; Forming part of the upper cut-off right with a constant slope to the right so that backlighting while having a cut-off boundary gradually gets higher than the optical axis to the front right; And includes a boundary area of an elbow portion formed between the left and right cut-off part forming the cut-off, where the left cut-off forming portion is formed thicker than the thickness of the right portion to form the cut-off thickness. Accordingly, the left side of the vehicle in front has a predetermined maximum brightness, is to the right side can be provided a lighting structure that meets the laws and regulations that specify a predetermined minimum brightness.
