Abstract

The utility model provides an improved night vision device for driver. The lens is made by a yellow optical glass layer and a blue optical glass layer adhered or is made by multiple layer of the medium film plated on the optical glass. The night vision can solve the problem that the big lamp of other side is dazzled and the front visibility of other car is not reduced when the driver meets other car in the night. The accident is reduced. The driver wears the night vision device for driver for a long time to reduce the fatigue of the eyes.

Description

Night vision device for driver

The utility model relates to a kind of improved night vision goggles, the chaufeur night vision goggles of wearing when particularly being applicable to automobilist's night driving.

Der Scheinwerfer mit FernlichtAbblendlichtStandlicht tends to make the meeting driver dizzy during the night driving automobile meeting, and traffic accident takes place easily.For this reason, driver's night driving must be worn night vision goggles.Night vision goggles in the market generally all are that yellow plastic or yellow organism glass make.This night vision goggles only are that white light is become gold-tinted, filter the light of a part of wavelength, do not dazzle the eyes problem but thoroughly solve.The night vision goggles of plastics or organism glass eyeglass making are simultaneously worn the health care that also is unfavorable for driver's eyes for a long time.

The purpose of this utility model provides a kind of novel chaufeur night vision goggles.It can reduce looking of the other side's light and see brightness, and is dazzle-free, does not reduce the preceding diopter of square car simultaneously, and driver's eyes is played a protective role.

The utility model utilizes the characteristic and the optical principle of light, adopts yellow optical glass and blue coloured light to learn glass cement and lumps together, or utilize technique for vacuum coating with yellow optical glass or colouless optical glass, plates multilayer dielectric film.It is the chaufeur night vision goggles that the eyeglass that utilizes said method to make is made glasses.

The yellow optics glass cement that the utility model provides close or optical glass on the night vision goggles made of plating multilayered medium film method; only allow the highest light of human eye luminosity function pass through; be that wavelength is near the light the 5500mm; the light of all the other most wavelength is filtered; like this; wear the night vision goggles that the utility model provides; during the night driving meeting; can not dazzle the eyes quad headlight; but the diopter before the square car does not reduce, thereby has significantly reduced the possibility that traffic accident takes place, and the night vision goggles that provide of the utility model are not worn for a long time and can be damaged eyes; comfortable, eyes there is protective effect.

Provide two embodiment and accompanying drawing thereof below, and be further described.

Fig. 1 is a cemented type night vision goggles eyeglass generalized section.Among the figure (1)---yellow optical glass, (2)---optical lens gelatin, (3)---blue coloured light is learned glass.The selection of optical glass material and thickness should make them satisfy when gummed is formed eyeglass and only allow the highest light of human eye luminosity function, and promptly near the light the wavelength 5500mm passes through, and filters the condition of other most of visible lights.

Fig. 2 is a plated film type chaufeur night vision goggles eyeglass generalized section.Among the figure (4)---yellow or colouless optical glass, (5)---deielectric-coating, it plates with technique for vacuum coating, and multilayer can obtain better effect so often.(6)---cover glass, it is to be bonded at optical glass on the plated film face with the optics transparent adhesive tape, effect is that the protective medium film is not scratched.It is only to allow the light of the highest part wavelength of human eye luminosity function to pass through that the multilayer dielectric film plated film requires.Use film plating process can obtain than the more gratifying result of cemented type.

The glasses that utilize above-mentioned eyeglass to make, promptly the chaufeur night vision goggles can reduce the degree of fatigue of chaufeur long-duration driving at night to eyes, significantly reduce accident rate, have tangible economic benefit and social benefit.

Claims

1, the chaufeur night vision goggles are made up of mirror holder and eyeglass, it is characterized in that eyeglass is to learn glass by yellow optical glass and blue coloured light to use the optical clear glue glued adhesion to form, or are made by yellow optical glass or colouless optical glass plating multilayered medium blooming.

2, chaufeur night vision goggles according to claim 1 is characterized in that plating the eyeglass that the multilayered medium blooming is made by yellow optical glass or colouless optical glass, are stained with the cover glass that one deck becomes with the optics glass on the plated film face.
