Embodiment Construction

[0098] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0099] figure 1 is a front view of a vehicle headlamp according to an embodiment of the present invention, figure 2 yes figure 1 The II-II line profile, image 3 yes figure 2 Sectional view of line III-III.

[0100] As shown in these figures, the vehicle headlamp 10 of this embodiment is a lamp installed on the right side of the front end of the vehicle. Eight lamp units 30, 50, 70 are accommodated, and each floor has two upper and lower floors and each floor has four configurations. In addition, in this vehicle headlamp 10 , light irradiation from these eight lamp units 30 , 50 , and 70 forms a low beam light distribution pattern.

[0101] In the light chamber, an inner panel 16 is provided along the translucent cover 14, and cylindrical openings 16a surrounding each lamp unit are formed at positions corresponding to the lamp units 30, 50, 70 in the inner panel...

Abstract

A vehicle headlamp that forms a predetermined light distribution pattern using light irradiation from a plurality of lamp units. It not only achieves thinning of the lamp but also allows the optical axes of each lamp unit to be aligned. Perform optical axis adjustments for multiple lighting units. A plurality of lamp units (30) using light-emitting elements (34) as light sources are tiltably supported on a common unit support member (20) to collectively adjust the optical axis. At this time, the unit support member (20) is configured such that the light source fixing portions (20B1) formed at a plurality of positions are in contact with the back surface (42a) and the outer peripheral surface (42b) of the support plate (42) that supports the light emitting element (34). The structure of the positioning recess (20d) is formed. This allows the light-emitting element (34) to be mounted on the unit support member (20) with high positional accuracy. Make the optical axes (Ax) of each lamp unit (30) consistent.

Description

technical field [0001] The present invention relates to a vehicle headlamp that forms a predetermined light distribution pattern by light irradiation from a plurality of lamp units. Background technique [0002] Usually, the vehicle headlamp is a structure that can form a low beam light distribution pattern with a cut-off line at the upper end edge, thereby not bringing glare to the driver of the oncoming vehicle, and at the same time, ensuring the safety of the driver of the vehicle as much as possible. forward visibility. [0003] In this case, Patent Document 1 discloses that a vehicle headlamp forming a low beam light distribution pattern is irradiated with light from a plurality of lamp units using light emitting elements as light sources. [0004] Patent Document 1: JP-A-2003-123517 [0005] By employing the lamp structure described in Patent Document 1, the lamp can be made thinner, but in this case, it is necessary to adjust the optical axis of each lamp unit.
