Technical field
The utility model relates to automobile lamp technical field, is specifically related to a kind of optical occluder component for car headlamp PES unit.
Background technology
Along with the high speed development of Highway Traffic Modernization and densification, on highway, strictly restriction uses high beam headlamp.On the other hand, when most of highway communication, lower beam headlamp is still vehicle and travels actual a large amount of driving lamp used.Therefore, the improvement of headlamp concentrates on the improvement of near, the distance light handoff functionality to dipped beam performance and described headlamp substantially.Such as, people using the modified head lamp system adopting and have complex set configuration, reach 50% to improve illumination efficiency.
PES is a kind of many ellipsoids headlamp lighting system, and PES headlamp can form long strip type headlight module with traditional high beam headlamp, side direction identification light together with PES fog lamp.This utilizes elliptic speculum (CAL) to realize in conjunction with optical projection technology.The screen of reflecting object projection can accurately determine light/dark dead line.The requirement special according to each, this light/dark transition can be designed to intensity and changes suddenly or gradually change, and makes it can obtain any desired geometry.Because lens lamp has the effect of optically focused, according to being a horizontal line on the wall, and reflection is loose, and obviously, PES is a preferably headlamp lighting system.

In car headlamp, before dipped headlamp reflector, shadow shield is set, be used for the direct light covered when car light is lighted upwards, otherwise can cause that oncoming vehicle driver's is seriously dazzling, and these light at random also can form a light curtain in rainy day or foggy environment before car, make the visibility of driver lower.
The dipped beam of car headlamp is asymmetric, namely (be formed on the photometric screen of front) light shape and be distributed with an obvious "cut-off"line, dipped headlights is avoided dazzling the eyes by the driver that "cut-off"line makes pedestrian and opposite send a car or uncomfortable, the height of dipped beam "cut-off"line means the distance of dipped beam irradiation distance on road surface, dipped beam "cut-off"line is too high easily make opposite send a car or pedestrian feels dazzling, too low then according to too near, make driver cannot see larger distance before car.
Asymmetric luminous intensity distribution has two kinds, and one is on photometric screen, and the horizontal component of "cut-off"line is at left one side of something, and right one side of something is the oblique line of one-tenth 15 degree on horizontal alignment.Another kind is right one side of something of "cut-off"line is horizontal alignment becomes 45 degree of oblique lines to the broken line of vertical range 25cm steering horizontal.The point of interface of left one side of something and right one side of something is the flex point (Hv also claims corner or mid point) of "cut-off"line, and this flex point is the key point forming light form of car lamp.
In addition, passing beam "cut-off"line or "cut-off"line corner (or mid point) inspection should be carried out to the headlamp that driving beam can not adjust separately, if tested dim head lights light beam does not have obvious "cut-off"line, or the irradiation position of "cut-off"line corner (or mid point) is when being equal to or higher than the irradiation position at driving beam center, this headlamp is defective, should change qualified headlamp.Because if carry out the adjustment of distance-light light beam, distance light adjusts rear dipped beam can be defective, and dipped beam adjusts rear distance light again can be defective, must change headlamp like this and just can address this problem.
At present on the optical centre PES of distance-light switching, the main flow mechanism realizing the switching of nearly distance light leans on the switching of one piece of movable shadow shield to realize, movable shadow shield forms "cut-off"line, some regulation test points near the dead line flex point of dipped beam, the minor structure on utilization activity shadow shield carries out partial occlusion realization.Minor structure on current movable shadow shield is done orthogonal on cross section, and as shown in Figure 1,1 be movable shadow shield, 4 be rectangle block minor structure, rectangle blocks the shadow that minor structure blocks border more clearly.In the automatic algorithm that dipped beam dead line flex point is caught, thisly sharply marginatedly to block, easily be mistaken for the flex point of dead line, when carrying out product acceptance test to car headlamp, easily cause the erroneous judgement of using light fixture regulation when checking dim head lights beam irradiation position, thus cause the erroneous judgement that whether qualified car headlamp product is.
