CN2374398Y - Device for preventing front light from dazzling - Google Patents

Abstract

The utility model discloses a device for preventing big light lamps in the front of vehicles from dazzling, which is mainly composed of a big light lamp in the front of a vehicle and a windshield in the front of the vehicle. The utility model is characterized in that the front part of the big light lamp in the front of the vehicle is additionally provided with a polarized light piece, the windshield in the front of the vehicle is also additionally provided with a polarized light piece, and an included angle of the polarized light direction and the horizontal direction of two polarized light pieces is 45 DEG. The utility model has the advantages of artful design and reasonable structure. When a driver drives and meets the vehicles in the night, the driver can be free from the stimulation of strong light. The originating rate of driving accidents in the night can be decreased.

Description

Headlamp thorn eye device before the anti-car

The utility model relates to a kind of device that prevents that the nighttime meeting car light is dazzling, particularly relates to a kind of anti-stab eye device that adds the preceding headlamp of car of polarized light piece and add the car front windshield formation of polarized light piece.

Present existing car lighting lamp is filament lamp mostly, assembles the high light post of back formation through lampshade, when the night travel meeting, tends to the other side driver with strong impulse, thereby brings threat to safe driving.

The purpose of this utility model provides a kind of, can effectively overcome above-mentioned defective, and during the night travel meeting, the driver can avoid the preceding headlamp thorn of the anti-car eye device that high light stimulates.

The technical solution of the utility model is, headlamp thorn eye device before a kind of anti-car, mainly form by headlamp before the car and car front windshield, its characteristics are: add polarized light piece before the headlamp before the car, also add polarized light piece on the car front windshield, the polarization direction of two polarized light pieces becomes 45 degree with the angle of horizontal direction.

Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, during the night travel meeting, the driver can avoid high light to be stimulated, and has reduced the incidence of sailing train operation accident night, the tool promotional value.

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

Accompanying drawing is the scheme drawing of the utility model embodiment 1.

Among the figure, install polarization direction becomes the forward slash direction of 45 degree with the angle of horizontal direction polarized light piece 2 before the car before the headlamp 1 additional, driver's car front windshield 4 installs additional and preceding polarized light piece 3 in the same way.The light that headlamp 1 is sent before the car only keeps the emergent light of the vibration of the forward slash direction that becomes 45 degree with the angle of horizontal direction behind polarized light piece 2.Because when two cars are met, the direction of polarization of the polarized light piece on the car front windshield of opposite vehicle is this car relatively, become the back slash direction that becomes 45 degree with the angle of horizontal direction, so polarized light piece before the aforesaid emergent light impassabitity car front windshield, and aforementioned emergent light shines the other side's body outline and background profile, because after the reflection on the direction of polarization different objects surface of polarized light or the refraction, promptly produce the rotation or the scattering of different angles, changed former polarization direction of light, become and to make the driver can clearly observe scenery by a large amount of nonopiate light of car front windshield.Thereby when having solved the night travel meeting effectively, the dazzling problem of headlamp before the car.

Claims (1)

1, headlamp thorn eye device before a kind of anti-car, mainly form by headlamp before the car and car front windshield, it is characterized in that: add polarized light piece before the headlamp before the car, also add polarized light piece on the car front windshield, the polarization direction of two polarized light pieces becomes 45 degree with the angle of horizontal direction.
