Abstract

The utility model discloses an optical structure for weakening impact of meeting strong light for vehicles. The optical structure is characterized in that optical polarizers, namely light polarizers, with same fixed polarizing angle are arranged on lamp shades of intense light sources of all vehicles; optical polarizers, namely window polarizers, with same fixed polarizing angle are also arranged on window glass of all vehicles; and polarization directions of the light polarizers and the window polarizers form polarizing angles of 0-90 degrees. With the optical structure, drivers only see light emitted from lamps of their own vehicles and weak light from lamps of coming vehicles during meeting when front window glass and lamp glass shades for cabs of all the vehicles are all provided with the polarizers. Therefore, the need for turning off lights or slowing down is avoided for the vehicles driven at night, and safe driving is also guaranteed.

Description

Weaken mutually the optical texture of high light impact during vehicle meeting
Technical field
The utility model relates to the application of optical mirror slip, relates in particular to the application of optical polarizer.
Background technology
Automobile at night travels vehicle with the opposite when meeting at highway, and for fear of dazzling the eyes of both sides' car light, the driver should close headlight, only opens lampet, slows down the speed of a motor vehicle, to avoid traffic accident.Driving license test subject one teaching material clear driving at night meets the opposite and sends a car in the time of should cutting out high beam, and Reduced Speed Now, in case the intersection of two car lights have the pedestrian by the time have an accident.But a lot of driver of low quality lamps of not turning up the soil, big light opening always, and the high light that headlight sends can cause to pedestrian's eyesight the vision blind spot, potential safety hazard occurs, numerous accidents cause thus.
At present the street lamp of some big and medium-sized cities is all night well-illuminated, or the shot-light in some construction site is all night well-illuminated, shines directly into residential building and see through window to shine into the room, and scientific research shows, if people's background when rest has light, the life-span will shorten.
The light that common light source sends, its vibration plane is not only limited to a fixed-direction but equally distributed on all directions, and this light is called natural daylight.Polarizer has the function of covering and seeing through to incident light, can make that vertical light or lateral light are a kind of to be seen through, a kind of covering.Can only allow vertical light pass through when at luminous object vertical polarizer being installed, light intensity does not weaken, and if when receiving the light object polarizer in vertical direction with certain angle is installed, the light intensity of reception will weaken.When this angle is 90 when spending, light will zero sees through.
The utility model content
The purpose of this utility model is according to the polarised light principle, weakens mutually the optical texture of high light impact when proposing a kind of vehicle meeting.
The technical scheme that the utility model is taked is, weakens mutually the optical texture of high light impact during a kind of vehicle meeting, it is characterized in that, it is the optical polarizer that the lampshade of all car intense light sources is provided with identical fixedly polarization angle, is called source polarizer; On the glass pane of all cars, also be provided with the optical polarizer of identical fixedly polarization angle, be called the vehicle window polarizer; The polarization direction of requirement source polarizer and vehicle window polarizer is the polarization angle of 0-90 degree each other.
Above-mentioned polarizer can also be polarizing coating.
The utility model has the advantages that: because the polarizer setting angle on all lamp shades is identical, polarizer setting angle on all glasss for vehicle window is also identical, and on the lampshade and the certain polarization angle each other of the polarizer on the glass pane, when the cloche of the front screen of automobile cab and car light is equipped with polarizer mutually in the time of so just guaranteeing all car carriage returns, the driver can only see the light that the car light of oneself sends from front window, and the light ratio of seeing the opposite car light is fainter, like this, automobile is when night running, namely do not turn off the light, do not slow down yet, can guarantee safe driving.
According to above-mentioned principle, can be generalized to the place of other intense light source irradiations.For example, all coat the each other polarizing coating of certain polarization angle of one deck on the street lamp of sending out high light that all dwelling houses are other and the household bedroom window, owing to selectively seeing through of light, high light will partly be weakened, therefore can reduce bedroom brightness at night, increase sleep quality, life-extending.And because polarizer is not installed on sun surface, so can not affect the use to natural daylight.
Optical texture of the present utility model is best suited for the automobile with glass pane, for only having car light not have motorcycle, electric motor car of window etc., even only install source polarizer at car light, with the automobile carriage return time, easily make the other side driver see oneself clearly, thereby greatly improved safety coefficient.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
The 1-source polarizer, 2-vehicle window polarizer.
The specific embodiment
As shown in Figure 1, weaken mutually the optical texture of high light impact during a kind of vehicle meeting, it is the optical polarizer that the lampshade of all car intense light sources is provided with identical fixedly polarization angle, is called source polarizer 1; On the glass pane of all cars, also be provided with the optical polarizer of identical fixedly polarization angle, be called vehicle window polarizer 2; Requiring source polarizer 1 and the polarization direction of vehicle window polarizer 2 is the polarization angle of 0-90 degree.
Above-mentioned polarizer can also be polarizing coating.
