Description

The self-propelled vehicle safety lighting fitting

The utility model relates to a kind of lighting assembly for vehicles, specifically a kind of lighting assembly for vehicles that utilizes the optical polarization phenomenon to be implemented in to weaken night the dazzle of self-propelled vehicle illuminating lamp, guarantee driving safety.

Self-propelled vehicle must be opened the front lit headlight and be used for illuminating road surface, the place ahead when night running, and the vehicle that comes to relative direction transmits meeting information simultaneously.When night, light was dark, especially night the field do not have under the situation of street lamp, the dazzle of vehicle front lit headlight and the strong contrast of low light environment generation on every side, the eyes of chaufeur thereby send a car in the stimulation opposite, make the other side's chaufeur be difficult to see clearly the vehicle and the road surface on opposite, thereby cause taking place traffic accident.

The purpose of this utility model is to provide a kind of self-propelled vehicle safety lighting fitting that can weaken opposite car light dazzle, ensure night travel safety.

For achieving the above object, the technical scheme that the utility model is taked is: the polaroid that an excellent transparency is installed on all self-propelled vehicle illuminating lamps, on the front windshield glass of each car or by the eyeglass (comprising goggles on motorcycle helmet) that chaufeur is worn, go up the polaroid that another excellent transparency is installed simultaneously, polaroid optical axis direction of installing on front windshield glass or the eyeglass and illuminating lamp polaroid optical axis direction form 30 ° of-80 ° of angles, can weaken the dazzle of the other side's lighting headlight thereby reach, can not influence driver's visual effect simultaneously again, make it can see and differentiate the purpose of the place ahead things clearly.

The utlity model has following characteristics:

1. two self-propelled vehiclees of this polarization illumination device are housed, under the darker situation of external light at night during meeting, the eyes of both sides' chaufeur can not be subjected to the intense stimulus of the other side's lighting headlight dazzle, can see and differentiate the object behind road surface, the place ahead, the other side's vehicle body and the vehicle body clearly, realize the night safe driving.

The optical glasses that 2. polaroid is housed not only is fit to chaufeur to be worn, and also is applicable to the personnel that work on highway night, as: traffic constable.They can see car clearly after wearing polarised light glasses, and can not stimulate the eyeball that can't keep one's eyes open because of the illuminating lamp forceful rays, have both helped the health care of eyes, safety that again can better safeguard work.

3. according to the polaroid optical principle, when natural daylight penetrates the polarized monolayer sheet (as sunlight, light), because of the energy that vibrates on the natural daylight all directions is identical, thereby when rotating the polarized monolayer sheet, natural daylight intensity equals the square root of former light intensity, and visual inspection does not have strong and weak the variation.Therefore, when the self-propelled vehicle that this safety lighting fitting is housed travelled daytime, the natural daylight of being injected by the windshield that polaroid is housed did not have strong and weak the variation, can not influence driver's visual effect.

Fig. 1 is the special optical filtering polarisation action principle figure of polaroid;

Fig. 2 is the structural representation of polarized light doubling glass in the self-propelled vehicle safety lighting fitting;

Fig. 3 is the structural representation of bonding polaroid in the self-propelled vehicle safety lighting fitting.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:

The optical filtering polarisation action principle that polaroid shown in Figure 1 is special.Light is passed through two polaroid P successively ₁And P ₂, P ₁Maintaining static, is that axle rotates P with light ₂, along with P ₂The orientation difference, the transmission light intensity changes.Work as P ₂When being in a certain position, transmission light intensity maximum (as A), after the position was changeed 90 ° thus, the transmission light intensity was kept to 0, and that light is fully by P ₂Institute stops that this phenomenon is called delustring (as B), if continue P ₂Half-twist, transmitted light become the brightest again.

According to the delustring principle of polaroid, we can be applied to it in the self-propelled vehicle safety lighting fitting.

The fabulous polaroid of one deck penetrability is installed on all self-propelled vehicle illuminating lamps, equally on the preceding windscreen of each car or the polaroid of one deck also is installed on the glasses of wearing by chaufeur (the comprising helmet glasses) eyeglass, and the polaroid optical axis direction of front windshield glass (or eyeglass) upper polarizer optical axis direction and illuminating lamp forms certain angle, reach and to see the other side's vehicle body clearly, weaken simultaneously quad headlight dazzle intensity to differentiate the purpose of the place ahead things.

It should be noted that polaroid can not weaken the illumination intensity of self-propelled vehicle self headlight.Reason is: road surface and the other side's car surface are coarse surface and nonspecular surface, and during coarse surface reflection line, produce diffuser reflection, and promptly light reflects with indefinite angle.That is to say that if the light of headlight goes through the vibration ejaculation with vertical direction behind the polaroid, when reflecting, light can vibrate in different directions, thereby can pass through the polaroid of the preceding windscreen in side.

Common polaroid is the crystal grain of evaporation one deck iodine sulfate quinine on X celluloid (polyvinyl alcohol) substrate that has stretched, and the stress of substrate can make the optical axis of crystal grain align, can obtain the very big polaroid of area like this.

Fig. 2, Figure 3 shows that the utility model specific embodiment: for the existing self-propelled vehicle that adopts doubling glass to make front windshield glass, can be when making the front windshield glass of processing machine motor-car, the polaroid 3 that penetrability is fabulous sandwiches in the doubling glass, and the front windshield glass of each self-propelled vehicle is formed successively by glass outer 1, bonded adhesives 2, polaroid 3, bonded adhesives 2, inner layer glass 4; And can make adhesive tape-like by the polaroid that penetrability is fabulous for the self-propelled vehicle that uses common case hardened glass to make front windshield glass, be that the polaroid adhesive tape is made of successively bonded adhesives 2, polaroid 3 and anti-scratch coating 5, directly with the polaroid adhesive tape bonding on the self-propelled vehicle front windshield glass.Certainly, also polaroid 3 directly can be bonded on glasses (or Casque for motorcycle driver) eyeglass that automobile driver wears, be made into special polarised light glasses (or goggles on motorcycle helmet).

Another polaroid is installed on the self-propelled vehicle illuminating lamp, and is different because of illuminating lamp, concave-convex surface is different, therefore, the polaroid adhesive tape can be made certain width, with they parallel self-propelled vehicle illuminating lamp outsides that is pasted on.Otherwise, if the polaroid that just must be suited by the various model car lights of special manufacturer production with a monoblock polaroid.Because of the car light case temperature higher, therefore should not be in illuminating lamp shade with the polaroid adhesive tape bonding.Certainly, also polaroid can be sandwiched in the doubling glass of making lighting lamp shade.

Polaroid (the P of the square front windshield glass of above-mentioned self-propelled vehicle (or glasses, helmet glasses lens) ₁) optical axis direction and the polaroid (P of the other side's self-propelled vehicle illuminating lamp ₂) optical axis direction form 30 ° of-80 ° of angles.As for the delustring power and the optical axis direction of self-propelled vehicle Lighting System, can formulate standard by national departments concerned.
