Background technique
In technical field of automobile illumination, in order to realize the different illuminations under different running environments, current headlamp
Tool is usually including far lighting and lower beam illumination.For high beam, range of exposures is wide, irradiation distance is remote, can be to drive
The person of sailing improves more wide visible area.Exactly because, may however, the also wide problem remote with irradiation distance of its range of exposures
Totally unfavorable influence can be caused to the normally travel of other vehicles.So introducing irradiation model in the lighting device of vehicle
It encloses and all lesser dipped beam modulated structure of irradiation distance.In this way, being used cooperatively by the switching between long-and-short distant light, guarantee that vehicle exists
It can normally be travelled under the bad environment of lighting condition.
There is the car headlamp product of a kind of high beam and dipped headlight integral type at present, is based on single light source, and in vehicle
One moveable anti-dazzle plate structure is set inside lamp, by the movement of control barn door, to carry out far lighting and lower beam illumination
Between switching.However, some light is blocked, so causing to a certain extent in the light issued due to light source
Optical energy loss, reduces the efficiency of light energy utilization of car light.
Also, when lower beam illumination, the region that above-mentioned light is blocked can be in lower beam illumination by the projection of projection lens
Above the "cut-off"line of field, an absolute dark space is formed, leads to not meet pressure standard.It is bright in order to reach lower beam illumination field
The standard of faint illumination above dark dead line, it will usually some micro-structure processing are done on projection lens, so that realizing makes portion
Light splitter projects the purpose of relevant range, this just proposes very high requirement to the machining accuracy of projection lens, bring compared with
High designs and manufactures cost.
Summary of the invention
