Abstract

A nighttime driving lighting system capable of preventing dizziness by the car light while driving at night operates based on the polarization principle. The whole system comprises two parts. The first part is a car light portion with a car light shade coated inside with a polarizing film and the second part is a glasses portion (See 1). While driving oppositely, from the perspective of the one who wears the glasses, the track of the coming car is moving from the center to the left side. Within this area, taking the track of the coming car as the standard, the polarizing lens or the polarizing film is arranged within in certain ranged at the proper position of the lens to make the polarization direction of the polarizing lens vertical to the polarization direction of the light of the coming car while other positions adopts the common lens. At night, the light enters the eye through the common lens at the center of the glasses lens when the car is far away, thereby will not be weakened and easy to be observed. While driving oppositely, the light enters the eye through the polarizing lens, thereby will be weakened, which will not bring about the dizziness.

Description

The driving at night illuminator

Technical field: this is practical to relate to a kind of driving at night illuminator of utilizing the polarisation principle.

Background technology: at present, utilizing glasses in the vehicling lighting system of polarisation principle to adopt whole eyeglass is polaroid entirely, and polaroid just has the part photoextinction to natural light, makes light weaken.After automobile lamp adopts polarized illumination, at night, two cars are when remote, the light of opposite automobile lamp relatively a little less than, the plane of polarization of adding polarized lenses is vertical with the plane of polarization of car light and produce delustring, makes the driver of wearing spectacles can not see the light of opposite automobile a long way off, can only wait until when two spacings are nearer and just can see, though not dizzy eye when this device makes meeting, the light of opposite automobile can not just be noticed by the driver a long way off, make travel safety reduce.

Summary of the invention:

The technical problems to be solved in the utility model is: for overcome delustring in the existing driving at night illuminator cause visual range dwindle and bring potential safety hazard.This use is novel to provide a kind of driving at night illuminator, and its dizzy eye of car light that can prevent to meet at night can not make the driver can't see automobile at a distance again.

The technical scheme that its technical matters that solves the utility model adopts is: automobile lamp attaches polarizer membrane (making the light polarization) in the illuminator, and plane of polarization is 45 ° of vertical direction right avertence.The eyeglass that the driver wears adopts local eyeglass polarisation, left side in wearer's (driver) optic centre, adopt polaroid (or attaching polarizer membrane) in the scope that is projected as benchmark of the track that during with meeting send a car in the opposite on eyeglass, remainder adopts common eyeglass, and plane of polarization also is 45 ° of vertical direction right avertence.Like this, nights two car in opposite directions and the distance situation far away under, the car light light of sending a car in the opposite is that the core (unpolarized) by eyeglass incides in driver (wearer's) the eyes! In this case, light is the delustring because of the polaroid that passes through eyeglass more not, and makes the wearer can just see the light of sending a car on opposite in two car wide aparts, prepares and carry out meeting in advance.When two car meetings, concerning the driver, the car light of sending a car in the opposite is the leftward position in optic centre, and this position of eyeglass is a polaroid, and the plane of polarization of opposite car light light is vertical with the plane of polarization of eyeglass, therefore light can be through the polaroid delustring, and the eyes that can not shine directly into the driver make the dizzy eye of driver, and it is safer that the driver is driven a vehicle.

The beneficial effects of the utility model are: the anti-dazzle eye effect when both having played the driving at night meeting can not make again and wear the traffic safety hidden danger that the back attention causes less than the light of sending a car at a distance.

Embodiment:

The car light lampshade inner surface attaches polarizer membrane.Polarization angle is 45 ° of vertical right avertence.The eyeglass that the driver wears adopts local eyeglass polarisation, as shown in Figure 1: in the left side of wearer's (driver) optic centre, adopt the polaroid (or attaching polarizer membrane) that the polarisation effect is arranged in the scope that is projected as benchmark of the track that during with meeting send a car in the opposite on eyeglass (guarantee opposite car light light can not direct irradiation wearer's eyes in), plane of polarization also is that 45 ° of vertical right avertence (making that the car light light plane of polarization of following the opposite to send a car is vertical) remainder adopts common eyeglass.

Claims (1)

1. driving at night illuminator of utilizing the work of polarisation principle, it comprises car light and the polaroid glasses that attach polaroid, it is characterized in that: the automobile lamp lampshade inner surface attaches polarizer membrane, in the whole eyeglass of glasses, the scope that be projected as benchmark of the track that during with meeting send a car in the opposite on eyeglass adopts polarized lenses or attaches polarizer membrane, and other parts adopt common eyeglass.
