Abstract

The utility model relates to a lighting device for a motor vehicle, particularly a lighting device when vehicles running meet at night. The utility model comprises the remote light of the vehicle front of the motor vehicle and a light polarized filtering light cover sheet which is arranged on the front surface of the light bulb of the remote light of the vehicle front. The inner of the front glass window of the motor vehicle is provided with a light polarized blocking sheet, and the vector sum of the polarized angles of the light polarized filtering light cover sheet and the light polarized blocking sheet is 90 DEG. So the utility model can avoid the danger of strong light lighting when two vehicles meet face to face, surrounding road surface and other objects are clearly seen, and simultaneously the vehicles which run at normal speed is not affected.

Description

Polarized light filter lighting device for motor vehicle

The utility model relates to a kind of lighting assembly for vehicles, especially refers to the illumination equipment that vehicle at night meets in travelling.

At present, (or daytime shady place) two cars meet (relatively) because night, and the high light of the preceding country beam of car separately makes the other side's chaufeur feel dazzling (dazzling the eyes), is easy to generate danger; So, before car by the country beam, set up a passing light (only sending the low light level), with traffic rules regulation, must close the country beam that goes out when nights two, car met again, and open passing light, because passing light irradiation distance short (30～50 meters) has to reduce the speed of a motor vehicle, in fact, still there is to make the other side's chaufeur feel dazzling dangerous hidden danger.

In view of this, the purpose of this utility model provides a kind of self-propelled vehicle polarizing filter illumination equipment, the country beam front is provided with polarizing filter lampshade sheet before the self-propelled vehicle car, simultaneously the polarization shade also is set in the pilot's line of vision front, the high light that the vehicle that is met in the front sends can not allow chaufeur feel dazzling.

The purpose of this utility model is achieved in that a kind of self-propelled vehicle polarizing filter illumination equipment comprises the preceding country beam of car of self-propelled vehicle, the bulb front of country beam is provided with polarizing filter lampshade sheet before this car, one polarization shade is set in the front glass window of self-propelled vehicle again, and the angle of polarization vector sum of the angle of polarization of above-mentioned polarizing filter lampshade sheet and polarization shade is 90 °.

The angle of polarization of above-mentioned polarizing filter lampshade sheet and the angle of polarization of polarization shade are with level at 45.

Above-mentioned polarization shade supports with movable supporting rack.

Above-mentioned polarization shade is bonded on the self-propelled vehicle front glass window.

Above-mentioned polarization shade is contained on the spectacle frame of hanging in car.

Owing to adopt such scheme: can avoid two car fronts to meet, the danger of strong illumination, and also road surface and other object are seen very clearly on every side, also do not hinder the vehicle normal speed to travel simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments scheme drawing.

Among the figure: 1, country beam 11, polarizing filter lampshade sheet 2, front glass window 3, polarization shade 31, movable supporting rack before the car

Country beam 1 is the electric light that is contained in self-propelled vehicle the place ahead before the car, be equipped with in its bulb front the polarizing filter lampshade sheet 11(that makes with polarizing filter glass as: from horizontal conter clockwise upward 45 ° or 30 ° of angle of polarizations), make this country beam 1 forwards penetrate polarized light to upper right oblique 45 ° or 30 °, obviously, the polarized light angle that the vehicle that travels in the same way penetrates is identical.

Polarization shade 3 also is to make with polarizing filter glass, the angle of polarization vector sum of its polarization angle and above-mentioned polarizing filter lampshade sheet 11 is 90 ° (that is: polarization shade 3 is from horizontal conter clockwise upward 45 ° or 60 ° of angle of polarizations), but, with the angle of polarization of polarizing filter lampshade sheet 11 and polarization shade 3 all from horizontal conter clockwise upward 45 ° be combined as good, not only cost is low, and use is also convenient.This polarization shade 3 is arranged in the front glass window 2 of self-propelled vehicle, can support with movable supporting rack 31, make polarization shade 3 removable (can remove sight line when not using), also can directly be bonded on the front glass window 2, even can also be contained in (not shown) on the spectacle frame of hanging in the car.

Principle of work of the present utility model is as follows:

If the polarizing filter lampshade sheet 11 of identical angle of polarization and the polarization shade 3 of identical angle of polarization are housed on the self-propelled vehicle that two are met;

When the angle of polarization of the polarizing filter lampshade sheet 11 of a self-propelled vehicle is from horizontal conter clockwise upward 45 °, promptly penetrate polarized light to the upper right corner, simultaneously the angle of polarization of polarization shade 3 also is from horizontal conter clockwise upward 45 °, and country beam 1 sees through the light that its polarizing filter lampshade sheet 11 shoots out before the car of positive another self-propelled vehicle that meets, for an aforesaid self-propelled vehicle, then be in the polarized light that penetrates to the upper left corner, at this moment, polarization shade 3 angle of polarizations of an aforesaid self-propelled vehicle are perpendicular with the polarized light of a positive car that meets, therefore, an aforesaid automobile driver be cannot see the high light (make and installation error because filter exists, in fact still can see faint hot spot) of positive surface launching; But two meet, and the high light of country beam 1 illuminates road surface and other object on every side before the car of vehicle, and chaufeur can clearly visible (because polarizing light irradiation behind object, loses polarization after reflection or the refraction).
