Embodiment Construction

[0039] Below, based on Figure 1 to Figure 6 Preferred embodiments of the present invention will be described. In each figure, the direction of the road seen by each part of the vehicle headlight or the driver of the vehicle equipped with the vehicle headlight is up=Up, down=Lo, left=Le, right= Ri, front = Fr, and rear Re will be described.

[0040] use figure 1 and figure 2 A vehicle headlamp used in the first embodiment of the aiming adjustment method of the present application will be described. The vehicle headlamp 1 of the first embodiment is an example of a left headlamp, and includes a lamp body 2 , a front cover 3 , and a headlamp unit 5 . The lamp body 2 is made of resin or the like and has an opening on the front side of the vehicle. The front cover 3 is made of translucent resin or glass, and is attached to the opening of the lamp body 2 to form a lamp chamber S inside. figure 1 The illustrated headlamp unit 5 is configured by integrating a low-beam headlamp u...

Abstract

The present invention provides a vehicle headlamp, its aiming adjustment method, and an aiming adjustment mechanism capable of displaying a high-beam light distribution pattern without redundant extinguishing ranges by synthesizing multi-segmented light distribution patterns. Among them, the aiming adjustment method of the vehicle headlamp (1) is performed based on the reference point on the light and dark boundary of the light distribution pattern (Hb, Lb), and the light distribution pattern (Hb) for high beam is formed by synthesizing many The intersection point (EP2) of the vertical light-dark boundary (Lf1) of a part (Hb3) of the divided light distribution patterns (Hb1-Hb4) and the horizontal light-dark boundary (CF1) of the low-beam light distribution pattern (Lb) is used as the reference point.

Description

technical field [0001] The present invention relates to an aiming adjustment method of a vehicle headlamp for adjusting the irradiation direction of a light distribution pattern, an aiming adjustment mechanism of a vehicle headlamp, and the vehicle headlamp. Background technique [0002] In [0021] of patent document 1, it is disclosed that the intersection point (elbow point) of the horizontal light-dark boundary cut-off line HC and the oblique cut-off line DC for the low-beam light distribution pattern of the front headlight is used as the reference point for the front headlight The detection method of said intersection point for light adjustment is carried out. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2007-190986 [0006] In the variable light distribution headlight (ADB) using an LED array composed of a plurality of independently turned on and off LEDs, in order not to cause damage to objects such...
