Title:
HEADLAMP FOR VEHICLE
Document Type and Number:
Japanese Patent JP2007157543
Kind Code:
A
Abstract:

To solve a problem that since low-beam light distribution is left-right asymmetry in a headlamp for vehicle providing light for low-beam light distribution when traveling by low-beam light distribution by providing reflecting surfaces for low-beam light distribution and traveling light distribution and obtaining traveling light distribution by compound light by providing light to both when traveling with traveling light distribution, light distribution of the compound traveling light distribution becomes uneven.

When providing light to the reflecting surface for the traveling light distribution, the reflecting surface is turned upward by 0.5 to 1.5 degrees simultaneously for increasing the amount of overlap of the low-beam light distribution and the traveling light distribution to eliminate a part which runs short of amount of light which especially tends to occur in a cut-off part on a side of the traveling light distribution. Thus, the problem is solved.
