Abstract

The utility model relates to a pair of electric liquid crystal light valve antidazzle eyeglasses. Each eyeglass of the utility model is formed by that a liquid crystal layer is clamped between two pieces of glass, and the outer sides of the two pieces of glass are respectively stuck with a layer of liquid crystal light valve eyeglass which is composed of a polarizing film; one of the polarizing film and the liquid crystal layer is are completely stuck together in the eyeglass. The polarizing film of one side or both sides of the eyeglass can be partly removed according to a definite radian shape, and the liquid crystal layer is filled in the eyeglass in the partial absence way according to a definite radian shape. When the utility model meets the irradiation of intermittent continuous strong light with a short gap, the dazzle of the user can not occur, and the utility model can be adjusted easily, so that the same pair of eyeglasses is suitable for eyes of a plurality of users. The utility model is especially suitable for drivers of the motor vehicles in meeting at night.

Description

Electronic liquid crystal light valve anti-dazzle spectacles

The utility model relates to safety goggles, refers in particular to a kind of electronic liquid crystal light valve anti-dazzle spectacles.

Electronic liquid crystal light valve lens; can change transmittance automatically in moment; because the outside of this lens is coated with two-layer polarizing coating; when the direction of the polarization angle of this two-layer polarizing coating is orthogonal; lens is pellucidity under the natural light condition: the inboard of polarizing coating is a layer glass; two glass therebetween are held liquid crystal layer; be embedded with transparency electrode between glass and the liquid crystal layer; this transparency electrode links to each other with the PHOTO-ELECTRONIC SWITCH IC OHEN DONGFANG of special use; therefore when rayed; the optoelectronic switch action, circuit is switched on, and electrode forms an electric field between the liquid crystal two sides; liquid crystal twists under electric field action; changed the direction of the polarization angle between the two-layer polarizing coating, the high light line can't be passed through, thereby reached degree of depth blackening in ten thousand/second; the protection eyes are not injured by high light; though this liquid crystal light valve eye can be pellucidity when natural lighting, rapid blackening when intense light irradiation, find that in practice this glasses have following two shortcomings:

1, runs into the extremely short strong illumination in gap, then easily form the eyeglass flicker, and in some occasion, for example: meet at night, if when running into fleet, the high light of automobile intermittently shines on the eyeglass, secretly can glimmer when bright during eyeglass, very easily cause dazzling the eyes of driver, have accident potential, influence traffic safety.

2, different users's eyes are different to the suitable degree that light and shade light changes, therefore, for same glasses, deepening speed was too slow when the somebody wore and can feel that eyeglass is met intense light irradiation, eyes are subjected to high light to stimulate, and other people can feel that eyeglass deepening speed is too fast, blind area when moment appears in eyes when wearing.

The purpose of this utility model is to provide a kind of part that the eyeglass of polarizing coating or lcd segment disappearance is set, the disappearance position is transparent all the time, and remainder unglazed according to the time be bright attitude, when being arranged, illumination is converted to dark attitude, when running into the high light intermittent irradiation, the wearer can adjust the bright dark state of eyeglass by the angle that changes sight line and surface level a little, makes this glasses have applicability widely.

The purpose of this utility model is achieved in that

A kind of electronic liquid crystal light valve anti-dazzle spectacles, comprise lens and spectacle frame, lens is by clamping liquid crystal layer in the middle of two sheet glass, the liquid crystal light valve lens that each bonding one deck polarizing coating of the outside is formed, and one of described polarizing coating and liquid crystal layer are imperfect laying in eyeglass.

Described lens can be by the certain radian shape, partly removes the polarizing coating of lens one or both sides and realizes imperfect laying, and is filled in the eyeglass with also can making the liquid crystal layer excalation and realizes imperfect laying.

During enforcement, have horizontal slotted eye on the girder of the picture frame of described spectacle frame, this slotted eye length is corresponding with lens length, and this slotted eye width is corresponding with the lens width, and the connecting portion of picture frame two ends and mirror leg has longitudinal fluting, to place power supply and circuit.

The utility model compared with prior art has following good effect:

1, run into gap extremely short intermittence during continuous strong illumination, because eyeglass has the subregion can conversion brightness, therefore when eyeglass remainder light and shade state changed, whole glasses can not glimmer, and the wearer can not dazzle the eyes, and eliminate safe hidden trouble.

When 2, wearing same glasses for the different users, only need to change the nose bed hedgehopping degree of glasses, just changed the angle of sight line and surface level, can reach and regulate light and enter what purpose of eyeball, thereby make same glasses can adapt to a plurality of wearers' eyes.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments

Fig. 1 is the utility model eyeglass one example structure synoptic diagram.

Fig. 2 is another example structure synoptic diagram of the utility model eyeglass.

Fig. 3 is the structural representation of the utility model mirror holder.

Fig. 4 is the front elevation of the utility model outward appearance.

Referring to Fig. 1, lens of the present utility model is divided into 5 layers of structure, be followed successively by polarizing coating 1, glass sheet 2, liquid crystal layer 3, glass sheet 4, polarizing coating 5, wherein (stain is represented) part is covered on the eyeglass 2 between the polarizing coating, and liquid crystal layer 3 shadow representation all riddle eyeglass.

Referring to Fig. 2, wherein polarizing coating 1.5 all is covered on the eyeglass 2.4, and liquid crystal layer 3 has disappearance, and only the filling of part is between eyeglass.

Referring to Fig. 3, have horizontal slotted eye 6 on the mirror holder girder, its length, width and eyeglass are corresponding, eyeglass can be inserted on the picture frame, add the eyebrow lid on it, promptly constituted complete glasses, be used for loading liquid crystal light valve control circuit components and parts in the groove 7 at mirror holder two ends, these control circuit components and parts are prior art.

Fig. 4 is a glasses front elevation of the present utility model, and two lenses all are that part is provided with polarizing coating or liquid crystal layer, and 8 are the imperfect position of laying among the figure, and set polarizing coating or the position consistency of liquid crystal layer in lens.
