Vehicle headlamp and vehicle headlamp system

Abstract

To provide a technique capable of achieving AFS control without using mechanical means. A vehicle headlamp (20R, 20L) for forming a low beam that illuminates a relatively lower region of a space in front of a vehicle, including a first light source apparatus (25) for forming a first irradiating light (100), a second light source apparatus (24) for forming a second irradiating light (101) with a width in the up-down direction that is smaller than that of the first irradiating light (100) on an upper end side of the first irradiating light (100), and a lens (23) that projects the light emitted from the first light source apparatus (25) and the second light source apparatus (24), respectively, wherein the second light source apparatus (24) includes a first light-emitting device array that extends in a first direction, and the first light-emitting device array includes a plurality of light-emitting devices capable of being individually turned on and off, arranged along the first direction.

Description

technical field [0001] The present invention relates to a light distribution control technology for controlling the irradiation range of the light according to the traveling direction (turning direction) of the own vehicle when the light directed toward the front of the own vehicle is irradiated. Background technique [0002] When driving a vehicle at night, the driver basically uses the headlights to illuminate the high beam (high beam) to confirm the front of the vehicle and switch to the low beam (low beam) as needed. However, due to the complexity of switching or the road environment There are also many cases of low beams being used. At this time, when the light is irradiated above a so-called cut-off line, glare may be given to an oncoming vehicle or a vehicle in front (hereinafter, these will be referred to as “a vehicle in front”). Therefore, in recent years, various light distribution control technologies have been proposed that use an image obtained by capturing a ...

Problems solved by technology

However, in the case of using such mechanical means, since there are movable parts, failures are relatively easy to occur, and there is still room for improvement in terms of reliability. Moreover, in order to maintain good operation, maintenance is required, so it becomes a problem. complex, there is room for improvement in this area
