Description
Technical field
The present invention relates to automobile lamp lighting field, particularly a kind of car lighting headlamp.
Background technology
Vehicle front lighting lamp system combines primarily of dipped headlights, high beam, wherein distance light far as far as possible in the brightness range of legal provisions illuminates front, and on the other hand, also must consider and can not sail the vehicle come to opposite, the vehicle of traveling ahead or pedestrian cause the sensation of dazzle.Therefore, the light distribution pattern of dipped beam suppresses dazzle, but its irradiation distance is limited, and driver not easily finds barrier remotely and Pedestrians and vehicles.In the situation words that the speed of a motor vehicle is higher, use dipped headlights illumination distances far away not, not easily find vehicle front barrier, use during distance light and easily cause again opposite and front vehicles and pedestrian dazzling, reduce road-ability and security.
Summary of the invention
The present invention devises a kind of car lighting headlamp, its technical problem solved is the light distribution pattern of automobile headlight low beam is suppress dazzle, but its irradiation distance is limited, driver not easily finds barrier remotely and Pedestrians and vehicles, if use high beam to cause vision to injure by opposite human pilot, be unfavorable for traffic safety.
In order to solve the technical problem of above-mentioned existence, present invention employs following scheme:
A kind of car lighting headlamp, comprise light source (2), ellipsoidal mirror (1), shading column (3) and projecting lens (4) composition, light source is placed in ellipsoidal mirror (1) first focus, shading column (3) is arranged at ellipsoidal mirror (1) second focus place, the focus of projecting lens (4) overlaps with ellipsoidal mirror (1) second focus, projecting lens (4) is placed in shading column (3) front, it is characterized in that: shading column (3) is provided with the projection of different in width and height, in shading column (3) rotation process, the projection of different in width and height produces specific light type, make that light is namely far away as far as possible illuminates road ahead, vehicle in the same way can not be made simultaneously, opposite vehicle and road pedestrian with dazzling feeling.
Further, shading column (3) is by shading column a(31) and shading column b(32) two parts form, shading column a(31) and shading column b(32) rotate respectively by a rotating shaft (33), on shading column a distribution bulge-structure (311) and shading column b on distribute bulge-structure (321) different, shading column a(31) and shading column b(32) be combined into a column structure, shading column a(31) or shading column b(32) make respective projection connect into different combination of protrusions to form multiple different light type in rotation process.
Further, dipped beam light type combination of protrusions is for the formation of dipped beam light type, and distance light light type is formed by rotating shaft (33), the irradiation light type formed when namely the position at multiple combination of protrusions place does not shut out the light.
Further, the combination of protrusions of dipped beam light type is positioned at shading column b(32) on include the horizontal plane forming dipped beam 45 ° of inclined-planes and top, the combination of protrusions of dipped beam light type is positioned at shading column a(31) on be a planar structure, this planar structure height is lower than shading column b(32) horizontal plane at top.
Further, the height definition of combination of protrusions is to form the combination of protrusions of dipped beam light type for benchmark, and the height that remaining combination of protrusions is the highest is no more than and forms the horizontal combination of protrusions height of dipped beam.
Further, shading column a(31) or shading column b(32) on projection, except forming the projection of dipped beam light type, remaining ledge width is increased progressively to both sides by centre, and the bulge-structure is namely narrower, and the bulge-structure width the closer to both sides is wider.Such as, the protruding preferable width near shading column a, b of centre is 1.5-3mm, and then adjacent bulge-structure preferable width 2-4mm, outwards increases progressively successively.
Further, shading column a(31) or shading column b(32) respective rotating shaft (33) rotates respectively by under a motor effect.
Further, described light source (2) be Halogen lamp LED, incandescent lamp, HID, LED or LASER Light Source.
This car lighting headlamp, compared with traditional car lighting headlamp, has following beneficial effect:
(1) the invention provides outside traditional dipped beam, driving beam, provide different illuminating bundles according to different road conditions in addition, namely ensure that driver has enough visuals field, ensure again not cause dazzling to pedestrian and other vehicles.
(2) the present invention is by controlling shading column a or/and shading column b rotates, and forms specific light type, makes that light is namely far away as far as possible illuminates road ahead, does not make again vehicle, opposite vehicle and road pedestrian in the same way with dazzling feeling.

Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 4, the present invention will be further described:
A kind of car lighting headlamp, it includes elliptical mirror 1, the projecting lens 4 that is placed in the light source 2 of ellipsoid first focus, is placed in the shading column 3 of ellipsoid second focus and the motor (not shown in FIG.) driving it to rotate, is placed in shading column front.
Light is sent by light source 2 and reflects through elliptical mirror 1, and the part projection be blocked on post 3 is blocked, and some light outgoing after projecting lens 4 reflects, the virtual photometric screen of 25m forms specific light type.
According to condition of road surface, whether detect this vehicle front has vehicle existence or opposite to have vehicle to sail, there are the information such as pedestrian on pavement, roadside, central controller controls shading column a is or/and shading column b rotates, form specific light type, make that light is namely far away as far as possible illuminates road ahead, do not make again vehicle, opposite vehicle and road pedestrian in the same way with dazzling feeling.
The dimeric benefit of shading column 3 has, and simplify shading column structure and make to control conveniently, additionally by the combination of two axle different angles, can form multiple specific light type, light type controls meticulousr.
Except traditional driving beam and passing beam, shading column of the present invention simply increases by two kinds of structures, just can realize multiple lighting result.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
