Embodiment

For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of antiglare film, and this film comprises brightness enhancement film DBEF, and described brightness enhancement film DBEF is characterised in that, can correct the light not becoming the right path at the light of the right path and pass through, reach anti-dazzle brightening effect.Antiglare film is for night vision anti-dazzle spectacles and automotive front baffle eclipser;

Particularly, when antiglare film is used for night vision anti-dazzle spectacles, middle layer is brightness enhancement film DBEF.

Application coating technique, brightness enhancement film DBEF is compounded in the middle of transparent optical material, make night vision anti-dazzle spectacles eyeglass, Material cladding is become 0.74mm to 1.1mm, reach the standard doing eyeglass, be cut into the small pieces of lens size again, curved through drying, cut-parts, be arranged on spectacle frame, make night vision anti-dazzle spectacles, dazzle can be filtered, its advantage is to reach polarization effect when not reducing too many brightness, filter veiling glare, dazzle, compared with the night vision antidazzle mirror made by electronic equipment with other, the glasses quality made is light, wear comfortable, the glasses made do not change extraneous color, keep the color of original object, see that object does not have aberration, by crossing, driver is seen that traffic lights can not have any impact.In addition, can also do complete mirror form, person uses conveniently to be furnished with glasses.

The night vision anti-dazzle spectacles made drives a car when being applicable to very much insufficient light or outdoor activities use.Be applicable to driver to drive at the night of avenue, can eliminate on the light dazzle of road both sides and road surface and diffuse, drive the night be particularly suitable for outside effect to use, prevent the high light sent a car in opposite, when countryside and rural light are not very bright, while anti-dazzle, accomplish the least possible minimizing light.

In addition, for people by bike, the automobile high light at night does not have the filtration of automobile front windshield, more dazzling concerning dazzle driver by bike, can make night vision anti-dazzle spectacles of riding, can make the helmet with night vision antidazzle mirror yet by antiglare film.Can well solve night by bike time intense laser interfere.

Because brightness enhancement film DBEF is half silver color light transmissive material, when urban lighting too bright at night, glasses both sides have image once in a while and produce, need to make night vision anti-dazzle spectacles with the larger picture frame of camber ratio, adopt 600 curved or 800 curved picture frames, the least possible sidelight that allows enters, and would not produce image.In addition, the mirror pin on glasses both sides is designed to broadside, shuts out the light and enters, also can avoid producing image.

Particularly, the upper and lower of described night vision anti-dazzle spectacles are triacetate fiber TAC, glass, polycarbonate film, any the high transmission rate optical material in resin.

When in selection TAC, PC, glass, resin, any one does night vision anti-dazzle spectacles compound substance, three kinds of materials respectively have relative merits: when TAC does compound substance, and advantage is that price is low, and shortcoming is that optical property is general, and anti-wear performance is poor.The advantage of glass material is good in optical property, and hardness is high, shortcoming eyeglass weight, frangible.When PC does compound substance, its advantage is high temperature resistant, indeformable, non-friable, shortcoming be not easy dry curved, price is high; How to select, need to determine in conjunction with the actual conditions of user.

Particularly, when antiglare film is used for automotive front baffle eclipser, upper strata is brightness enhancement film DBEF.

Brightness enhancement film DBEF one side is coated optics glue, be fitted in variable color liquid-crystalline glasses driver's one side dorsad, be clipped on Light barrier for automobile plate, when light is strong by day, Photoinduction device starts liquid crystal electric supply installation, there is provided voltage or provide voltage less, liquid-crystalline glasses energy printing opacity at this moment but opaque to variable color liquid-crystalline glasses.The dazzle of DBEF membrane filtration, heightens the color in conjunction with liquid-crystalline glasses, and the more light of specific filtration resistance makes sunlight not dazzling, and the object seen is more clear, eye is fine more comfortable.By day, because DBEF film is attached to the one side of driver dorsad, dark outer bright situation in being formed, daytime can not produce mirror effect, only can filter diffuse reflection, plays the effect of filtering dazzle.

Simultaneously, variable color in evening liquid-crystalline glasses is when light is inadequate, through photosensitive material induction, power supply starts power supply, liquid crystal molecule bleach, DBEF film can filter opposite and to send a car high beam high light, the diffuse reflection of light on filtration road surface, can not make driver be subject to high light and dazzle is disturbed and impact driving, under transparent liquid crystal, polarization light increases by more than 30% than daytime, makes the more clear wash rice of object seen.In evening car, light is dark, and car UV light is bright to be crossed in car, does not also worry producing minute surface phenomenon.

Utilize DBEF film to be fitted on variable color liquid-crystalline glasses, the problem that will reduce brightness anti-dazzle daytime and brightness anti-dazzle will be increased evening can well be solved simultaneously.Be arranged on the frequency modulated light plate of shelves before automobile, clip with chuck, round-the-clock anti-dazzle effect can be realized.

In addition, DBEF film is compounded in the middle of the transparent material such as polycarbonate or acrylic board (Acrylic, organic glass), make the eyeglass that has certain degree of hardness and thickness, cut into the eyeglass of about 300mm*120mm size, making chuck is clipped on Light barrier for automobile plate, also can make an anti-dazzle eyeglass of simple night vision and use.

When making color-changing vehicle eclipser and the anti-dazzle eyeglass of night vision, when urban lighting too bright at night, have some minute surface phenomenons, draw by minute surface bottom to driver direction, form a very little angle with vertical direction, minute surface phenomenon will disappear, there is the anti-riot film of grey on present automobile both sides, if at this moment do not open the window of pilothouse driver side, do not allow light enter, minute surface phenomenon can be eliminated.

Particularly, the middle level of described automotive front baffle eclipser is variable color liquid crystal structure, and lower floor is transparent explosion-proof membrane structure.

The cardinal principle of variable color liquid-crystalline glasses is the object reaching light modulation according to the orientation of liquid crystal molecule under voltage effect, and liquid crystal molecule is arranged in a linear in the energized state, at this moment liquid-crystalline glasses printing opacity and transparent; During off-position, liquid crystal molecule is scattering state, at this time liquid crystal film printing opacity but opaque.

Blow-out disc is a kind of film providing defencive function, and film one side scribbles high viscose glue water, when liquid-crystalline glasses is broken, glass can be sticked together and not cause producing debris damage human body, play safeguard protection effect.

The utility model makes night vision antiglare film by using brightness enhancement film DBEF, DBEF part can be conveyed self polarization direction directional light and be passed through, and can through reflection correct and the not parallel light of self polarization become parallel after pass through again, using this film to do, night vision antidazzle mirror can do than common light polarizing film will increase by more than 30% brightness, reach the effect of anti-dazzle blast again, make the object seen more clear, be particularly suitable for night driver driving and use.
