Description
Technical field
The present invention relates to lighting device technical field, more particularly to a kind of multiple light courcess high beam.
Background technology
In lighting device technical field, particularly in technical field of automobile illumination, in order to realize different running environments
Different illuminations, current illuminator is typically to include far lighting and lower beam illumination, for high beam, its range of exposures
Wide, irradiation distance is remote, and more wide viewing area can be improved for driver, exactly because however, also its range of exposures is wide
With irradiation distance it is remote the problem of, totally unfavorable influence may be caused to the normally travel of other vehicles, so, in vehicle
The all less dipped beam modulated structure of range of exposures and irradiation distance is introduced in lighting device, in this way, by between long-and-short distant light
Switching is used cooperatively, it is ensured that vehicle can be travelled normally under the not good environment of lighting condition.
For current distance light modulated structure, it, which is mainly, includes light source and is collected and anti-for light source to be emitted beam
The reflection shield of irradiation area is mapped to, because its range of exposures is fixed, so, in irradiation area, simply by the presence of there is wherein one
Divide and other vehicles or pedestrian are adversely affected, it is necessary to use the less dipped headlight of range of exposures, although dipped headlight energy
Enough to reduce to other vehicles or the adverse effect of pedestrian, still, because its range of exposures is smaller, can also limit driver can
Viewed area, is unfavorable for driver's observation ambient conditions.
That is, current high beam, although it can provide more wide irradiation area for driver, but its
Use environment is but significantly limited, based on it is such the problem of, need to design the high beam that a kind of irradiation area can change at present.
The content of the invention
