Abstract
This invention is the automobile lighting method that can effectively filtrate the dazzling light from the opposite at night. It replaces or adds on the transparent materials of the windshield and the front lights of the automobile by the transparent materials that has 45 DEG polarizing angle with the horizontal. When the head-on two autos meet, the polarizing direction of the opposite light is 90 DEG with that of the windshield and so it can be filtrated. Therefore, this invention makes use of the polarizing phenomenon to filtrate the dazzling light from the opposite.
Description
Affiliated technical field
The opposite technical field of dazzling light of sending a car when the present invention relates to utilize the polarisation of light performance to eliminate driving at night significantly
Background technology
At present, vehicle all needs to open headlight and illuminates pavement behavior when night running, is convenient to driver observation.But when the vehicle intersection, the opposite dazzling light of sending a car often makes driver's eyes be subjected to very big stimulation, can only see the headlight that the opposite is dazzling, and other darker object all be cannot see.At this moment, traffic accident often taking place easily, also causes tired driver easily.Existing method is constantly to strengthen the headlight of vehicle.Though so temporarily illuminated pavement behavior, sent a car to the opposite again simultaneously and caused more serious stimulation.Everybody constantly increases the brightness of headlight, has just caused a kind of vicious circle, does not only deal with problems but also wasted the energy.
Summary of the invention
In order to solve above these problems, the technical method of my invention is the principle that adopts polarised light.Not only can effectively filter the light of sending a car in the opposite, and the object that can clear view be shone, so just can fundamentally solve the opposite dazzling problem of car light of sending a car to this car light light.
The method that I adopted is that the headlight at vehicle replaces existing transparent material or adds one deck polariscope in addition with polariscope, make polariscopic polarization direction and horizontal plane in angle of 45 degrees, allow only direction of vibration that headlight penetrates polarised light from the horizontal by 45 degree angles.In addition, also replace on the front windshield of vehicle with the identical polariscope of polarization direction.Like this, the light that the object that this car headlight light is shone reflects because the direction of vibration is identical with the polarization direction of windshield, just can see through windshield smoothly, is arrived by driver's observation.When all vehicles are all pressed installation like this.Send a car and done 180 degree rotations in the horizontal direction with regard to suitable this car in the opposite.At this moment, polariscopic polarization direction on headlight of sending a car in the opposite and the windshield just in time becomes 90 degree angles with this car headlight with polariscopic polarization direction on the windshield.The direction of vibration of light that its headlight sends just in time becomes 90 degree angles, and has significantly been filtered with the polarization direction of this car bumper wind glass.Equally, the light of this car has also been filtered by the polariscope of the windshield on opposite.So just reached and clearly to have observed the object that this car headlight is shone, can filter the send a car purpose of dazzling light of opposite again significantly.
Claims (3)
1. Optical filtering lamp on the headlight of vehicle, replaces existing transparent material or adds one deck polariscope in addition with polariscope, also adopts the identical polariscope of polarization direction to replace windshield on the windshield of vehicle.
2 Optical filtering lamps according to claim 1, its feature are the polariscopes before the automobile front lamp, and are identical with polariscopic polarization direction on the windshield before the vehicle, all become the angles of 45 degree with horizontal plane.The direction of vibration of the light that headlight sent is also from the horizontal by 45 angles of spending.
3 when all vehicles are all installed after this manner, will produce best effects.
