Abstract
The utility model relates to a vehicle headlight without dizzy light, which doesn't change the original lighting system. The front of a vehicle headlight cover is provided with a polariscope for a driver to wear; the polariscope is made of polarizing membrane stuck on a glass plate by optical resin gum and rubber rings on the both sides of the glass plate, and use pressing rings to connect the vehicle body via screws; or the polariscope is made of the polarizing membrane directly stuck on the outer surface of the headlight cover via optical resin gum. The polarization direction of the polariscope accords with the direction of the polarizing light emitted by the polariscope and forms an angle of 90 DEG with the polarizing light of the other vehicle. Therefore, the utility model without the dizzy light during night meeting reduces traffic accidents. The utility model has the advantages of simple structure, easy fabrication, convenient operation and strong applicability.
Description
The utility model relates to a kind of motor-driven vehicle meeting at night free from glare car light.Be to load onto polarizer in the front of front car light, the driver puts on the polarised light glasses consistent with the polarized light that sends from square car light, makes the driver can avoid the niphablepsia of the other side's car light, also can see the road ahead situation clearly, thereby improves the safety of night travel.
Existing automotive anti-glare illuminating lamp is to reduce light intensity when the meeting or dwindle its illumination zone and weaken and dazzle the eyes light source mostly, and when meeting, both sides all need close country beam mutually or intermittently close country beam mutually, but its anti-dazzle effect is unsatisfactory.Chinese invention patent prospectus CN1034695A discloses 3 one kinds of night meeting of vehicles blinding free illuminations and looks square method and device, and this device is to utilize the other side's illumination to make intersection both sides' illuminating lamp and the staggered variation rapidly repeatedly between illumination and non-illumination condition of the light valve of retaining before driver eye by photosensitive control setup.Because the vision retention effect of human eye, being embodied on the illuminating effect is to make the driver feel flicker slightly, but does not feel the stimulation of dazzling the eyes of the other side's lighting car light.Common photosensitive control action is subjected to the meeting distance limit, and when meeting spacing during greater than 150 meters, photosensitive control is just inoperative, and the driver will not see road and the Reduced Speed Now of having to because of feeling the other side's dazzling light.Also, make the illuminating effect of illuminating lamp descend owing to illuminating lamp conversion rapidly between illumination and non-illumination condition, and also corresponding shortening in its service life.In addition, light valve adopts liquid crystal light valve, and is unfavorable to houselights, makes the people feel that illuminating effect is obvious decline, even do not see road ahead.
Task of the present utility model is that the polarized light source that provides a kind of meeting to throw light on, and polarised light glasses matching used with it make its effect not be subjected to the restriction of meeting spacing.The driver can see the road (comprising the road of distance beyond 150 meters) from square car light irradiation clearly, free from glare when having realized meeting, and must not slow down, therefore the driver has improved service conditions, so the safety of night travel also improves thereupon.
The technical measures that realize the utility model task and take are, the polarizer that throws light on when being provided with in car light the place ahead for meeting, and promptly the headlight of each car all is equipped with its direction of polarization and horizontal surface angle at 45, by upper right side direction bevelled polarizer to left down.The driver also puts on the polarised light glasses of identical direction of polarization.Like this, two cars are when nighttime meeting, owing to go in the same direction, the direction of polarization of the automobile lamp polarizer that comes from the direction of polarization and the opposite of square car driver glasses is " deceiving " so the driver sees the other side's car light just in time at an angle of 90, the free from glare phenomenon; And since the direction of polarization of driver's glasses with identical from the direction of polarization of square car polarizer, when seeing other object that illuminates from square car light, then sight line is unaffected.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a fundamental diagram of the present utility model.
Fig. 3 is the utility model installation site scheme drawing.
In conjunction with the accompanying drawings structure of the present utility model and embodiment are described below:
Referring to Fig. 1, existing car head light mainly is by lampshade 4, lamp bowl 5 and bulb 6 are formed, be provided with polarizer 10 in its place ahead, it is by polarization film 1, two rubber rings 2 and 3, glass board 8 and trim ring 7 constitute, and the polarised light glasses 9 of polarizer 10 that the free from glare car light is provided with by car head light and the place ahead thereof and supporting same direction of polarization is formed.
Polarization film 1 is the film of being made through the crystal of directional process by a kind of, and its photometric characteristics is equivalent to optical slot, the direction of corresponding transmitted light intensity maximum.After the polyvinyl alcohol dissolving, filter, purify, the condensation film forming, stretch orientation is handled, and soaks the iodine drying at last and makes.
Angle between polarization direction of light and the polarization direction is α, then transmitted light intensity I and incident intensity I
ORatio be:
I:I
O=COS
2α, during α=90 °, I=0;
When α=0 ° or 180 °, I=I
O
Polarization film 1 adopts optical resin gum to be bonded on the glass board 8 of 1.5-3 millimeters thick, and cushioning effect is played in two rubber rings 2 and 3 both sides that are placed on glass board respectively.Convex edge by trim ring 7 connects with 3～4 screws and car body and constitutes polarizer 10, also can directly polarization film 1 usefulness optical resin gum be attached on the surface of lampshade 4, is coated with the last layer optical resin gum again at the periphery of polarization film 1, in case raise.The size and dimension of polarizer and the size and dimension of various car light are suitable.
Principle of work to described free from glare car light further specifies as follows now:
Referring to Fig. 2, the other side sends a car, no matter its distance how far, polarised light glasses by the driver removes the light of seeing that the other side's headlight (band polarizer) sends, because direction of polarization and the other side's car from square car driver polarised light glasses send the polarization direction of light just in time at an angle of 90, absorb a certain direction light vibration according to polarization film, and only convey the characteristic that the vertical light vibration of this direction is passed through, just in time absorb the polarized light that the other side's lamp sends from square car driver glasses, before driver eye, present " deceiving " look, and, fundamentally eliminated glare phenomenon to seeing clearly in the polarized light that sends from square car object that light illuminated and the ground consistent with the direction of polarization of glasses.
Advantage of the present utility model:
1. when meeting at night, the free from glare phenomenon can be because of the dazzle accident;
2. simple in structure, polarization film is made with polyvinyl alcohol, low price;
3. debug simple and easyly, easy to use, applicability is strong.
