Method for preventing glare of vehicle light and two-dimension lamp

The invention belongs to method and two-dimension lamp that a kind of glare phenomenon that vehicle was produced obtains weakening when night, big light opening was driven a vehicle.

At present, before self-propelled vehicle and the partially self car illuminating lamp is installed, is used for illuminating the road surface of vehicle front, be convenient to vehicle at night running.The automobile front generally is equipped with headlight and lampet, equal big light opening during cruising, because car light brightness is big, the zone of vehicle both sides and road surface are very dark, the zone of car light and vehicle both sides and road surface brightness differ too big and form " dazzle " this poor lighting phenomenon, make chaufeur and the pedestrian on the road on the vehicle that the opposite goes in the same direction feel dazzling, do not see the road surface whether situations such as pedestrian, roadblock are arranged, particularly be about to when driving vehicle that headlight travels and meet, only feel to be left in the dark, cannot see whatever, very easily cause traffic accident.Up to now, the method for taking that weakens dazzle is: self-propelled vehicle when nighttime meeting, each self closing headlight, opening lampet travels, though this method has weakened glare phenomenon effectively, the brightness of vehicle front ground-surface is reduced greatly, automobile driver is difficult for seeing clearly the road surface situation equally.Moreover this method just adopts when self-propelled vehicle and self-propelled vehicle meet, and self-propelled vehicle and bicycle and pedestrian switching off the headlamp not when meeting, thereby pedestrian's influence was also very big on glare phenomenon was satisfied the need.Therefore, glare phenomenon usually is the immediate cause of night travel generation traffic accident.

The present invention just provides and a kind ofly can weaken glare phenomenon effectively, can improve road surface brightness again, and not only favourable vehicles meeting but also do not influence the up people's walking in road reduces the method and the supporting with it two-dimension lamp thereof of night travel traffic accident.

The object of the present invention is achieved like this: on the vehicle except existing to the illuminating lamp of front irradiation, on vehicle, increase the illuminating lamp that the space and the road surface of vehicular sideview are illuminated, and be controlled by same switch to the illuminating lamp of front irradiation is in parallel, like this, vehicle is when night, big light opening was driven a vehicle, the area of space and the ground of vehicular sideview also are illuminated, make the luminance difference between headlight and territory, car lateral areas and car dypass face obviously reduce, thereby the glare phenomenon that automobile front lamp is formed is obviously weakened.Meeting between the self-propelled vehicle, self-propelled vehicle and road surface pedestrian meet, all needn't switching off the headlamp, and the pedestrian can think that neither headlight is too dazzling on chaufeur and the road, can see opposite car side ground-surface situation again clearly and relieved walking, the generation of traffic accident in the time of can obviously reducing night travel.For car side space and road surface are illuminated, can use the general automobiles illuminating lamp, but, because the light deflector of general automobiles illuminating lamp mainly is a concave mirror surface, light is played converging action, range of exposures is little, effect is not good enough, preferably can adopt two-dimension lamp provided by the present invention, this lamp and ordinary lamps are made up of lampshade, lamp housing, bulb, light deflector equally, different is the minute surface of light deflector, and the light deflector of two-dimension lamp is main in the horizontal direction if it were not for concave mirror, but is formed or be made up of part concave mirror and convex mirror and plane mirror by convex mirror and plane mirror; In the vertical direction, last, middle part is plane mirror or concave mirror and plane mirror, the bottom is a convex mirror.The reflective mirror of two-dimension lamp so the light that filament can be sent fully launches in the horizontal direction, illuminates the scope bigger from headstock to the tailstock owing to adopted this specific combination mode, and in the vertical direction cover car dypass face improves road surface brightness.

Owing to adopt such scheme, both can weaken the glare phenomenon that vehicle caused when big light opening is driven a vehicle at night effectively, can increase car side space and ground-surface brightness again, and make the long road surface of car side, pedestrian's safety on ensure safety meeting and the road by light lumine.
