Abstract
The present invention relates to an anti-dazzling technique for the background lighting of back and side lamps during vehicle meeting. Two non-signal lighting lamps are arranged on both sides of the back part of a vehicle; a plurality of side lamps are arranged on both sides of a vehicle body. When two vehicles meets at night, two drivers of the two vehicles turn on the back lamps and the side lamps when changing to near lamps for background lighting for lighting self vehicle bodies, and roads and scenery behind the vehicles; namely, the vehicles light advanced roads and vehicle bodies for each other. When a vehicle meets a motorcade or meets other vehicles on urban streets and trunk highways, a driver only turns on the side lamps for lighting the self vehicle body without turning on the back lamps; in this way, because the brightness contrast between headlamps and the background is reduced, a dazzling phenomenon can be eliminated for ensuring safe driving.
Description
The present invention relates to the side lamp that a kind of anti-meeting nighttime meeting is dazzle the eyes.
At night, when two automobiles were met, the light of the other side's car light formed strong visual stimulus to both sides' chaufeur and passenger.The viewer can only see the light that the other side's car light " radiates brilliant light ", does not see car body, road and the scenery of car light back, and then produces a kind of sensation of dazzling the eyes, and causes the accident sometimes.So-called " meeting is dazzle the eyes " phenomenon that Here it is.
At present, the state-of-the-art automobile that countries in the world produce does not all have substantial technological improvement at anti-meeting aspect dazzling the eyes, and closes lamp far away when its basic way remains meeting and uses low beam instead, simultaneously deceleration.
The side lamp that the object of the present invention is to provide a kind of anti-nighttime meeting to dazzle the eyes.
For principle of the present invention is described, at first analyzes and produce the reason that meeting is dazzle the eyes phenomenon.
" Hundred Thousand Whys " one piece of data according to the China's publication seventies, scientist did following test: go to take intense light source with camera, video camera, video recorder, the image that has only light source on photo and the movie and television film, not " radiance ", but the people but has the sensation of a kind of " radiating brilliant light " when directly with the naked eye going to see light source, this is can reconcile flexible radial hyaline cell tissue because the crystalline lens of people's eyeball has, these radial tissues make to see through lenticular light has formed " radiating brilliant light " on retina image just.By day with strong indoor of light, even the direct visual light source of people is also also dazzle-free.This be because: substantial light according under, the scenery reflected light rays around the light source is stronger, the brightness contrast of light source and scenery is approaching, can form brightness image relatively uniformly on the retina, " radiance " hide and do not live other scenery images, can not dazzle the eyes phenomenon so can not send out.But in the dark, instead the low light level of a match makes us dazzling the eyes, and this is because scenery is too dark on every side, the match luminance brightness is little, and very big with the brightness contrast difference of dark scenery, the image of " radiance " can cover very dark scenery image on retina, dazzles the eyes phenomenon and produce.As seen, the reason of dazzling the eyes phenomenon is in the brightness of light source, and is the light source and the brightness contrast of scenery on every side.The essence of dazzling the eyes phenomenon is the vision system of people in certain visual environment and the collimation error that produce limited to scenery image brightness resolution capability, and then influence the judgement of brain, and a kind of phenomenon of formation.
Specific to the meeting phenomenon, by day, two car phase meetings of turning on high beam of head lamp lamp, lamp from dazzling, but and dazzle-free, this be because the brightness of scenery greater than car light brightness; At the night of moon bright position, meeting is dazzle the eyes phenomenon and not serious; When a car and a fleet meeting, because the rear of each car of front all illuminated by the car light of back, so though light is strong and dazzle-free, when just meeting with last car, dark background just makes the people dazzle the eyes again; The phenomenon of dazzling the eyes when having only the two cars meeting is that " radiance " of light have covered the very weak image of dark background on the retina of human eye because of the background dark equally, therefore forms and dazzles the eyes.
Can reach a conclusion from last surface analysis: nighttime meeting is dazzle the eyes the basic reason of phenomenon and is not lain in the brightness of car light, and is the car body of car light and car light back background, and the brightness contrast difference of road scenery is too big.
Side lamp provided by the invention can illuminate the road and the scenery at car body and car rear, and the brightness of headlight and the brightness contrast difference of car light back background are reduced, and dazzles the eyes phenomenon thereby eliminate meeting.
The purpose of the side lamp that the anti-meeting of the present invention is dazzle the eyes realizes by following mode:
A kind of anti-nighttime meeting dazzle the eyes side lamp, this lamp is installed in car body two sides, this lamp is made up of lamp housing, catadioptre, light source, lampshade; It is characterized in that: cover light source under the shell of side lamp is oblique, be used to cover the horizontal direct light of light source to both sides, the side lamp inwall is the diffuser reflection minute surface of non-focusing, and the lampshade of side lamp has can be to the lens arrangement of car body outside refracted ray; The brightness of side lamp is less than the headlight and the back light of automobile.This side lamp external attached type is installed in the side or the built-in side that is installed in car of car.
Be described further below:
Under the side of two headlights of automobile and two sidecar windows and boxcar two upper lateral parts several side lamps are installed respectively, what of side lamp are determined according to the vehicle size.The lamp housing of side lamp should be oblique following, cover the direct light of light source to two sides, make side lamp can illuminate car body and two side line roads, but other viewers on both sides' chaufeur and the road can not direct visual side lamp light source, side lamp is not direct projection or reflected light rays in car also, in order to avoid form car internal reflection image at the vehicle window inwall.The brightness of side lamp can be less than the front and back lamp.The inwall of side lamp is the diffuser reflection minute surface of non-focusing, and lampshade has the lens arrangement to two side refracted rays.
In automobile rear two sides two non-signals illumination back light is installed simultaneously, the brightness of back light is not less than the headlight of automobile.The principle of the structure of back light, reflected light rays and refracted ray is identical with headlight, but back light does not carry out distance light and dipped beam conversion, and every back light is only installed a light source.Opening back light can be to the illumination of car rear, and essence is to illuminate road ahead for the other side's chaufeur.
The mounting means of side lamp can be taked two kinds of modes according to vehicle:
First kind is that external attached type is installed, and for example external attached type side lamp and back light can be installed in the outside, compartment in the boxcar; Back light and side lamp are installed on used car can take external attached type to install.Second kind is built-in installation, processes some pit shape lamp nests when producing the car shell, in adorn built-in side lamp.In like manner, also can adopt this installation method under the operator's compartment vehicle window of truck.
The back light of car and passenger vehicle is also suitable takes built-in mounting means.
Certainly, back light and side lamp also will have corresponding lead, switch, and this is a general knowledge, repeats no more.
The concrete using method of the present invention is as follows:
1, when having only two car meetings, both sides' chaufeur will be opened back light and side lamp when using passing light instead, implement background illumination, illuminate road behind self car body and the car, scenery, hold in fact be both sides each other the other side's chaufeur illuminate road, car body and the scenery in the place ahead, dazzle the eyes phenomenon thereby eliminate.
2, when two fleet meetings, because the rear of fwd car is all illuminated by the car light at rear, do not drive back light so only open side lamp, prevent that so also back light light the other side chaufeur from forming the direct light irradiation, last car then needs out back light (whether chaufeur can be observed the rear by rear-view mirror car).
3, at avenue and the big backbone highway of vehicle density, only open side lamp, do not drive back light.
Principle of the present invention, the installation site of back light and side lamp and using method also are applicable to other ground maneuver vehicle, for example trac., motor bike, train etc.
The side lamp that adopts the anti-nighttime meeting that provides of the present invention to dazzle the eyes can be eliminated meeting effectively and dazzle the eyes phenomenon, guarantees traffic safety.
