Abstract

A night light meeting system for automobiles is composed of a polarizing frame driving mirror, a front lamp polarizer and an automatic switching device. The main technical characteristic is that the headlight polarizer is controlled by an automatic switching device and has different kinetic energy of two light rays of polarized light and natural light for illumination. When meeting, the automatic switching device pulls the artificial polarizer to the front of the headlight, the light transmission axis of the artificial polarizer is orthogonal to the light transmission axis of the driving polarizer worn by the driver, and the driver can not see the direct light of the headlight. The road surface is illuminated by two cars and four headlamps together, reduce the traffic accident at night. The automatic switching device resets the front lamp polarizer after meeting is finished, and the natural light illumination is automatically recovered.

Description

Automobile bright lamp at night can truck system

The utility model relates to a kind of Lighting System of realization automobile bright lamp at the night meeting of being made up of polarization driving mirror, head lamp polariscope and automatic switching control equipment.

Along with increasing sharply of automobile pollution, the number of times of traffic accident, dead wounded or disabled number and direct economic loss constantly increase.The whole world is every year on average because of traffic death 700,000 people according to statistics, wounded or disabled 1,000 ten thousand people to 1500, ten thousand people, direct economic loss more than one hundred billion dollar (research report of World Health Organigation's issue on April 6th, 1993).Wherein 2/3rds occur in developing country.China's situation is shown in subordinate list, and have 180 people's death in traffic accident average every day, and the people that dies in per 10000 chassis years leads 35.7 times into Japan, is 30 times of the U.S., 24.8 times of Britain, 14 times of France.Traffic accident has become maximum social effects of pollution peacetime.

The night traffic accident rate is 2～2.5 times of daytimes, and night, unfavorable factor had:

(1) night light difference, underlit, reduced the visual performance of chaufeur.

(2) harmfulness dazzle (physiology dazzle) makes chaufeur feel dazzling, and eyesight descends.The time that returns to safe eyesight is about 10 seconds.Cause blindly and drive a vehicle about 150 meters.

(3) limitation of traffic law." the Chinese people altogether state regulation of road traffic control " the 49 regulation about vehicles meeting is " street lamp or underlit road on must apart from opposite send a car 150 meters beyond mutually close country beam not having night, uses passing light instead "." when chance the other side car does not cut out country beam, should promptly slow down and use continuously the instant and near light change-over switch, signal the other side closes country beam ".If close country beam, then with 30 meters farthest of passing light illuminations, less than vehicle stopping distance.As if not closing country beam or replacing with instant and near light, the chaufeur that is sent a car in the opposite causes vision harm, and the probability that gets into an accident is bigger.The information that the chaufeur vision is obtained accounts for full detail more than 80%.The abominable visual condition of night travel is the major cause that produces the traffic accident at night.

Existing technical scheme is fixed in polariscope on the automobile front cover, polaroid sheet is affixed on the automobile cab front window, though when meeting, can solve the rolling eye problem, but when normal driving, then because of polariscope, polaroid weaken intensity of light more than 50%, and fail all the time in practice, to obtain to promote.

The purpose of this utility model provides a kind of self-propelled vehicle Lighting System, and this system has natural daylight and two kinds of light source automatic shifting function of polarized light: night during cruising with common natural lighting; When night during meeting, be transformed to polarized illumination automatically, cooperates with the dual-purpose driving cover mirror that the driver wears, realize that switch-on distance light bright lamp meeting is non-dazzing, with minimizing traffic accident at night.

The purpose of this utility model is achieved in that utilizes polariscope 2 to make the natural daylight of head lamp 1 outgoing become linearly polarized light, and make its plane of vibration in vertical direction with 45, this linearly polarized light plane of vibration just with polarization driving mirror 3 light transmission shaft quadratures, light can not see through, and promptly preceding irradiation 1 direct light can not be injected in the driver eye 4.Meeting finishes, and head lamp polariscope 2 automatically resets, and recovers natural lighting.

The structural property of a kind of embodiment is as follows:

Head lamp 1 front adds the artificial polariscope 2 at a light transmission shaft and vertical angle at 45, this polariscope is by automatic switching control equipment 5 controls, when 150 meters of spacings are come on the opposite (this distance can suitably be set up as required), the front that automatic switching control equipment 5 is moved artificial polariscope 2 to head lamp 1 automatically, the light that makes outgoing is linearly polarized light.Chaufeur is worn polarization driving mirror 3, its light transmission shaft and vertical angle at 45, vertical with polariscope 2 light transmission shafts.White light biplate quadrature light transmittance is 0.1～1%, and the eyes 4 of chaufeur be can't see by head lamp 1 and directly penetrated next light, realizes seeing that lamp is non-dazzing.Polaroid sheet individual layer mean transmissivity reaches 42～45%, and relative two cars are being driven 4 headlights that add polariscope 2 and illuminated the road surface during meeting, and road illumination reaches bicycle 90% when the travelling of turning on light, and can satisfy the requirement that normal driving is observed.After meeting finished, automatic switching control equipment 5 was pushed head lamp polariscope 2 to a side automatically, recovered natural lighting, did not need driver's operation.Night travel visual field light intensity is basic identical when meeting and solo running, and no light and shade sudden change reduces the harmfulness dazzle, keeps the good eyesight of chaufeur, safe driving.

Polarization driving mirror 3 has two kinds of single layer structure and double-deckers: Fig. 2 (a) is single layer structure, and is identical with the common spectacles form, but its eyeglass makes with polaroid sheet; Fig. 2 (b) is a double-decker, and outer eyeglass is made by polaroid sheet, and the internal layer eyeglass can be selected any eyeglass or not add eyeglass according to the needs of chaufeur.When double-deck effect is meeting outer eyeglass is put down, meeting finishes and can hold up up.
