Abstract

A strip-type antiglare vehicle lamp is composed of multiple barrier-shaped light-limiting partitions made of thin metal plates and horizontally arranged behind the transparent glass lampshade of headlight of ordinary motor vehicle and close to bulb. The width of the partition plates is wider at the middle part and narrower at the upper and lower parts, and a gap is reserved between the partition plates and the reflector. The light limiting partition board can block the light rays diffusely reflected by the reflector, only the light rays in the horizontal direction can irradiate towards the right front from the middle of the partition board, although the light limiting partition board has influence on the brightness, the light limiting partition board can obviously reduce the dizzy stimulation to the eyes of the driver of the opposite party during meeting, and the effect is more obvious when the distance is closer. Simple structure, low cost, convenient use and easy popularization.

Description

Strip type antiglare light for vehicle

The utility model relates to a kind of automobile-use illumination equipment, exactly, relates to a kind of slatted anti-dazzle eye car light.

During the automobile night running, whenever meeting, the strong illuminating ray of head light makes that the eyes of both sides' chaufeur of meeting are dizzy and opens not open; Especially since two cars at a distance of nearly 30 meters the time, along with the continuous shortening of its distance, the dazzling degree of light is but more and more severe, and the eyes of chaufeur can't be opened, thereby can not control working direction and cause the collision accident of car crash.The accident of this bitterness occurs repeatedly, for fear of the recurrence of this tragedy, people have thought many measures of the dizzy eye of car light when overcoming meeting, for example: the transparent glass of head light is made the net form concave-convex type, though improved action slightly, but still can not effectively prevent the dizzy reaction that backlight is dazzling.Have the manual change light that utilizes the other side's illumination principle to make original head light to change the device of automatic beam change into again, can reduce the reaction time difference of human body, still, chaufeur still is reluctant to adopt.The while automatic beam change because may when two cars are met, make them receive the other side's light simultaneously hardly; In case two cars have between the change light time successively, in this section still can produce the dizzy eye of above-mentioned thorn in the period intense light irradiation, traffic accident takes place not living bearing circle in the dizzy eye of the driver who is sent a car in the opposite.Still more, this device construction complexity, fetch long price is unfavorable for utilization and extention.

The purpose of this utility model provides a kind of simple in structure, cheap, helps the slatted anti-dazzle eye car light of penetration and promotion.

The utility model is achieved in that it includes transparent lamp shade, lamp housing, light deflector and lamp, it is characterized in that: in a side of the close bulb in the back of transparent lamp shade, the barrier shape light-limiting clapboard that polylith is made with sheet metal horizontally is housed, the width of these dividing plates does not wait, be that centre portion broad, upper and lower sides part is narrower, should and light deflector between leave the gap.

The utility model is simple in structure, and is cheap, can not change the head light external form of existing various automobiles at all, only needs the transparent lamp shade back in its lamp housing to install light-limiting clapboard additional just.Both helped applying (comprising the head light of transforming existing various automobiles and self-propelled vehicle), also saved trouble, and need not become light and can be subjected to the welcome of chaufeurs and be willing to adopt because of easy to use.In fact, the utility model is exactly on the basis of original front headlight of motor vehicle, installing barrier shape light-limiting clapboard additional at transparent glass cover rear side constitutes, according to test, after installing this occluder additional, to hang down 2～5% before the repacking of the illumination brightness ratio of head light, but the dazzling dizzy degree of the other side's chaufeur of meeting is then reduced more than 20～80%.And the utility model wide application can be fit to the head light of various model automobiles or self-propelled vehicle, also is one of its characteristic.The utility model not only can alleviate the other side's chaufeur when meeting dizzy eye stimulates, and on satisfying the need by bike the pedestrian on personnel and trade also have and alleviate the same effect that dizzy eye stimulates.These all play good effect to ensuring traffic safety.

Fig. 1 is the new structure diagram of this practicality

Fig. 2 is a front elevation of the present utility model.

Referring to Fig. 1,1 is the transparent glass cover of automotive headlamp among the figure, the 3rd, the car light shell, 4 are mounted in the tungsten filament lamp on the lamp socket 6,2 is exactly that light-limiting clapboard (claims again: occluder), it is mounted in the side of the rear side of transparent lamp shade 1 near bulb 4, is horizontally, is made up of many slatted dividing plates made from sheet metal.Fig. 1 has clearly illustrated that the width distribution situation of these light-limiting clapboards: i.e. the dividing plate broad of intermediate portion, two side portions is narrower up and down, should leave the gap between itself and the light deflector 5, for the light incident and the reflection in lamp source.Fig. 1 has also shown the principle of work of this device: shown in the dotted line is from lamp 4(light source) light that sends after light deflector 5 reflections, the passage of light of going out from the space illumination between the light-limiting clapboard 2.Because the resistance hurdle of light-limiting clapboard 2 has quite a few to be blocked from light deflector 5 irreflexive light, have only horizontal direction reflected light can between the dividing plate 2 to external radiation.So, load onto the light-limiting clapboard in this device, brightness of illumination is slightly lost, but therefore make car light only toward the dead ahead centralized lighting.Because two cars when meeting, all are on traffic way separately basically, two cars laterally still have certain distance.After using the utility model, because of light is concentrated to the dead ahead illumination, the diffuse light around reducing, the dazzling light of dazzling the eyes when just making meeting weakens greatly; Especially what deserves to be mentioned is that two cars are at a distance of near more, the light of dizzy eye reduces obvious more, has just in time overcome the former near more dazzling seed of trouble drawback of headlight distance of sending a car.

The utility model is implemented, and installs light-limiting clapboard additional with the head light of common vehicle and realizes that the sheet metal thickness of use is 0.35～0.5 millimeters thick.The light-limiting clapboard width that is contained in car Santana is 40～50 millimeters, and the spacer width that is contained in liberation automobile and 212 Beijing jeeps is 20～40 millimeters.Border test factually, when the lateral route interplanar distance when two cars are met is 6 meters, at two cars at a distance of 120 meters the time, reducing the light glare is about 20%, at a distance of 50 meters the time, reducing the light glare is about 50% at two cars, when two cars during at a distance of 30 meters, the improvement effect that light is dazzling is 80～100%, and promptly two car light light do not disturb mutually basically, influenced yet.

External form of the present utility model is just the same with the head light of original vehicle, can directly use original car light to convert, and, it install and use to the no any change requirement of car body itself.As long as two self-propelled vehiclees of meeting or automobile are not on same straight line, the light of this device irradiation all has different the alleviating of degree to dazzle the eyes glare to both sides' chaufeur, and two cars are at a distance of near more, and this effect is obvious more.
