Description
Technical field
The present invention relates to a kind of car headlamp, especially relate to the anti-glare headlamp of a kind of vehicle.
Background technology
Vehicle front lighting lamp system is mainly combined by dipped headlights, high beam, wherein distance light is far away as far as possible road ahead and the guideboard information of illuminating in the brightness range of legal provisions, and on the other hand, also must not consider and can sail next vehicle to opposite, the vehicle travelling above or pedestrian cause the sensation of dazzle.Therefore, the luminous intensity distribution figure of dipped beam is to suppress dazzle, but its irradiation distance is limited, and driver is difficult for finding barrier and Pedestrians and vehicles at a distance.For driving safety, general urban road is seldom opened high beam.The head lamp structure of common distance-light one comprises light source, speculum, blocker, drive motors and lens.
Summary of the invention
The present invention has designed the low-cost anti-glare headlamp of a kind of vehicle, the technical problem of its solution is that the luminous intensity distribution figure of automobile headlight low beam is to suppress dazzle, but its irradiation distance is limited, driver is difficult for finding barrier and Pedestrians and vehicles at a distance, if use high beam to cause vision injury by opposite human pilot, be unfavorable for traffic safety.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
The low-cost anti-glare headlamp of a kind of vehicle, comprise the left headlamp and the right headlamp that is arranged in vehicle right side arranged with vehicle left side, left headlamp is identical with right headlamp structure and all by light source (1), speculum (2), blocker (3) and projecting lens (4) form, reflective mirror (2) is elliptical mirror, light source is placed in first focus of reflective mirror (2), blocker (3) is arranged at reflective mirror (2) second focus places, the focus of projecting lens (4) overlaps with reflective mirror (2) second focuses, it is characterized in that: blocker (3) exists a plurality of fins (32) that block, a plurality of fins (32) that block stop respectively different sizes and difform light, left headlamp and right headlamp complement each other to form a plurality of types of not sharing the same light by blocker (3).
Further, the rotating shaft (31) of described blocker (3) pivots, rotating shaft (31) is provided with a plurality of fins (32) that block, wherein, fin La is used to form left headlamp dipped beam light type, fin Ra is used to form right headlamp dipped beam light type, and left headlamp distance light light type Ld or right headlamp distance light light type Rd are formed by rotating shaft (31), the light type forming when a plurality of positions of blocking fin (32) place do not shut out the light.
Further, adjacent two block angle initialization between fin (32) according to following principles: after determining and blocking the height of fin (32), each blocks fin (32) and rotates to behind precalculated position, other block fin (32) and can not disturb arriving the formed smooth type of fin (32) that blocks in precalculated position.
Further, each blocks fin (32) and highly defines that to take fin La or the fin Ra that forms dipped beam light type be benchmark, and all the other fin maximum heights are no more than horizontal fin La or the fin Ra height that forms dipped beam "cut-off"line.
Further, blocker (3) can be along rotating shaft (31) 360 ° of rotations under the effect of motor.
Further, described light source is Halogen lamp LED, incandescent lamp, HID, LED or LASER Light Source.
Further, projecting lens (4) is aspheric surface convex lens.
The low-cost anti-glare headlamp of this vehicle is compared with existing vehicle head lamp, has following beneficial effect:
(1) the present invention is irradiated owing to realizing the multiple smooth type of headlamp by blocker, for driver provides comfortable enough lighting environments far away, and can be to opposite vehicle, vehicle and roadside pedestrian cause dazzling in the same way.
(2) left headlamp of the present invention, with right headlamp except forming identical upper beam type and dipped beam type, can also form other mutually mutually different smooth types, is combined to form multiple smooth type, for different condition of road surface provides suitable illumination by two lamps.
(3) the present invention is simple in structure, and low cost of manufacture is beneficial to and is widely used.

The specific embodiment
Below in conjunction with Fig. 1 to Fig. 7, the present invention will be further described:
As depicted in figs. 1 and 2, headlamp comprises does headlamp and right headlamp, and wherein left headlamp has identical internal structure with right headlamp: light source 1, reflective mirror 2, blocker 3 and projecting lens 4, consist of.
Light is sent by light source 1, and through speculum 2 reflection, the part device 3 that is blocked blocks, and another part light device 3 that is not blocked blocks, and penetrating projecting lens reflects and is mapped on 25m photometric screen, forms specific light type.
Left headlamp and right headlamp are except forming same dipped beam light type and distance light light type, and remaining light type is not identical.
In structure as above, the blocker of specific design right headlamp and left headlamp as shown in Figure 3 and Figure 4.
The fin Ra wherein arranging on the blocker 3 of right headlamp in Fig. 3 is used to form dipped beam light type, and the light type that fin Rb, fin Rc form is corresponding to light type schematic diagram in Fig. 7.
The fin La wherein arranging on the blocker 3 of left headlamp in Fig. 4 is used to form dipped beam light type, and the light type that fin Lb, fin Lc form is corresponding to light type schematic diagram in Fig. 7.
As shown in Figure 5, distance light light type Ld is formed by blocker rotating shaft, the light type forming when the position at fin La, Lb, Lc place does not shut out the light.
As shown in Figure 6, fin La is a laminated structure, and this laminated structure exists a breach, and this breach is an obtuse angle.Fin Lb is a laminated structure, and this laminated structure exists a breach, and this breach is a right angle.Fin Lc is a laminated structure, and this laminated structure exists a breach, and this breach is also a right angle.The difference of fin Lb and fin Lc is that fin Lb breach area is less than fin Lc breach area.
By the combination of left headlamp and right headlamp, form light type schematic diagram and present in Fig. 7.Left headlamp and right headlamp can be combined into 16 kinds of illumination types.
Therefore, left headlamp except forming identical upper beam type and dipped beam type, can also form other mutually mutually different smooth types with right headlamp, is combined to form multiple smooth type, for different condition of road surface provides suitable illumination by two lamps.
By reference to the accompanying drawings the present invention has been carried out to exemplary description above; obvious realization of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present invention and technical scheme to carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all in protection scope of the present invention.
