Abstract
The invention discloses a device for preventing dazzling of an automotive headlamp with an inlaid light baffle screen. The light baffle screen 2 with an depression angle alpha is arranged above a light source of an inlaid headlamp 1 parallel to the ground FM, a light barrel 6 is composed of the light baffle screen 2 and the lower part 3 of the light barrel 6 and is inlaid behind a cover of a conventional headlamp 11, namely a transparent glass cover 4 and in an automobile body 7. The lower edge C of the light baffle screen 2 and the bottommost point B of the lower edge of the headlamp with an inlaid horizontal light source are arranged in the same plane parallel to a pavement, and light baffled by the light baffle screen is emitted below a headlamp of a coming car. Light emitted by an inlaid headlamp shiner 8 and a parabolic reflection surface 9 is baffled by the light baffle screen of a certain length AC, and accordingly, eyes 5 of a driver of the coming car cannot see a dazzling light source 1, and only light beams emitted from the transparent glass cover 4 and parallel to the plane of the pavement can be seen from the dark place. Therefore, dazzling of the driver of the coming car due to the automotive headlamp when cars meet is avoided.
Description
The technical scheme art of technical field application claims protection relates to non-portable projection illuminating apparatus or system, and destination device is dazzled in especially a kind of anti-vehicle electricity headlight or spotlighting.
During background technology vehicle meeting at night, oncoming vehicle electrical headlight shines eyes grow dim, and does not see Chu.Chu's danger close is not seen during craspedodrome, more dangerous when turning round, and legal liability are bad defines, and are difficult to manual control and constraint.
Its dazzling reason: existing vehicle electrical headlight is all arranged on before car body, and parabolic emitting surface is directly installed on car fore shell, instead of built-in, during meeting, electricity headlight is in a flash, and eye from dark place to daylight, then arrives dark place; Pupil from large to small, become large again, to adapt to the change of light, this light and shade intensity of variation is larger, and the process that eyes adapt to light is longer, occurs the procedure of adaptation in a few second sometimes, cause moment blinding, so that the judgment travelling width is declined, car speed and perceived distance power is declined, and causes the generation of traffic accident.
For solving the dazzling problem of electric headlight, there is the device of various light trap lucifuge, as CN2068639U discloses a kind of not dazzling Vehicular illumination device, a shield assembly be made up of the screen of cylinder and some arrangements is added before automobile front, light is penetrated by screen space and throws light on, due to the shielding action of screen, the other side's chaufeur cannot see light source and parabolic reflector and not dazzling, its shortcoming is that Illumination intensity weakens due to many being in the light of screen, and during driving, front has screen shadow to rock, and affects illuminating effect.
Summary of the invention the object of this invention is to provide a kind ofly to be avoided some screen shading strips and affects the illumination intensity of electric headlight, and to jolt with car during driving and the vehicle electrical headlight of screen shadow shaking phenomenon that rocks, make opposite chaufeur of sending a car be unlikely and dazzle destination device.
For achieving the above object, the present invention adopts built-in level electricity headlight light trap light-blocking structure, namely by being parallel to the light source on road surface and arranging flat light trap in this light source front upper place and be in the light, the lower edge of light trap and light source lower to nadir being parallel to face road, the distance point being clipped to road surface is equal.The angle of depression of light trap is between 0 ~ 30 °, preferably at about 5 °.Be parallel to the light source on road surface at the highway of light trap effect nutation according to vehicle front, electricity headlight penetrates from the lower edge of the straight level of light trap, below (below driver's eyes) electric headlight height that its most high light line impinges upon that opposite sends a car, at two cars within the scope of more than 100 meter, opposite send a car the sight line of chaufeur shield by the light trap of certain length, cannot see the parabolic reflector of this car light source and electric headlight, the chaufeur that therefore send a car in opposite can not be dazzling.Owing to not using the screen shielding light source of some arrangements, therefore, neither weaken the exposure intensity of electric headlight, the shaking phenomenon of the screen shadow also do not caused because of rocking of vehicle body.
In order to attractive in appearance, by light trap, light cylinder lower part, apparatus of the present invention of light source and parabolic reflector composition are held back in the rear of former vehicle electrical front lamp cover after optical axis direction, stealthy in automobile body shell, are in fact a kind of built-in electric headlights.
Light trap can be not reflector, also can be that reflecting plate is made.

The highest light being parallel to road surface that BCE-penetrates from light trap
Angle (i.e. the angle of depression of light trap) between AC and the BC of α-light trap 2
In embodiment Fig. 1, built-in electric headlight 1 comprises built-in electric headlight luminous body 8 and built-in electric headlight parabolic reflector 9, the light being parallel to road surface that built-in vehicle formula electricity headlight 1 sends removes the light of light trap more than edge C through light trap 2 gear, remaining light passes between light trap 2 and light cylinder lower part 3, penetrate through transparent glass cover 4 again, illuminate the vertical section region in CEFNG, i.e. the remote zones of vehicle.Now, the send a car eyes 5 of chaufeur of the other side cannot see the built-in electric headlight luminous body 8 of this vehicle and the luminous componen of parabolic reflector 9 thereof, only see the light beam penetrated from transparent glass cover 4, therefore can not be dazzling to the chaufeur of direction running, and the built-in electric headlighting of this chaufeur is abundant, without shaking shadow interference.
Here, light trap 2 and light cylinder lower part 3 can be set to not reflecting part, as white; Also parasite form can be set to, as minute surface.Transparent glass cover 4 also can use other transparent material.
In order to the illumination allowing built-in electric headlight 1 send obtains farther, α angle should be allowed less as far as possible, on the one hand because the length AC of light trap 2 is by the restriction of body structure, should be as far as possible long; Reduce the height of the AB of built-in electric headlight 1 on the other hand as far as possible.In addition the left and right illumination width of built-in electric headlight 1 should be suitable.
Built-in electric headlight 1 after improvement, the light cylinder 6 be made up of light trap 2 and light cylinder lower part 3 is built in the rear of former car electricity headlight lamp shade, is hidden in the below car body 7 on car bonnet both sides, attractive in appearance like this.Transparent glass cover 4 replaces the lampshade position of traditional electrical headlight 11, plays printing opacity, dust-proof, waterproof action.
Built-in electric headlight 1 and light cylinder 6 also can be located on the level attitude between two original electric headlights, only adopt an electric headlight, substitute original two electric headlights.
