Description

Anti-parallel light glasses based on semi-permeable membrane

Technical Field

The invention belongs to the technical field of glasses, and particularly relates to anti-parallel light glasses based on a semi-permeable membrane.

Background

When driving at night, drivers often use high beam lights in urban areas for bright and clear vision, and the behavior can shake eyes of the opposite drivers, so that the drivers can not see the pedestrian road condition clearly, and meanwhile, the drivers are irritated, and traffic accidents are easily caused; the existing products aiming at the problem in the market are yellow polarized glasses, and light polarization is utilized to filter out light in certain specific polarization directions; since the main source of influence of the high beam on the driver is strong parallel light, it is necessary to design glasses capable of reducing the strong parallel light.

Disclosure of Invention

In order to effectively solve the problems in the background technology, the invention provides anti-parallel light glasses based on a semi-permeable membrane, and the specific technical scheme is as follows;

the anti-parallel light glasses based on the semi-permeable membranes comprise a glasses frame and lenses (1) embedded in the glasses frame, wherein a plurality of semi-permeable membrane lenses (2) are obliquely arranged on the front end lens surface of each lens (1) at equal intervals, the front ends of the semi-permeable membrane lenses are coated with the semi-permeable membranes (3), the inclination angles of the semi-permeable membrane lenses (2) are 35-55 degrees, and the vertical distance between the semi-permeable membrane lenses (2) which are arranged at intervals is smaller than the vertical height of the semi-permeable membrane lenses (2) after inclination;

preferably, the semipermeable membrane (3) is electroplated on the semipermeable membrane lens (2), and the material of the semipermeable membrane (3) is titanium dioxide;

preferably, the semi-permeable membrane lens (2) is adhered to the front end mirror surface of the lens (1);

compared with the prior art, the invention has the beneficial effects that: the device adds the semi-permeable membrane lens at the front end of the original spectacle lens, so that part of strong light can be reflected when the strong light enters the lens in parallel, and further the strong light which can be absorbed into the glasses of a driver is reduced, thus the light intensity received by the eyes of the driver is reduced by half, and the problem of dazzling is greatly reduced; the reflected light is reflected to the road surface in front of the automobile and in the short distance, so that the lighting effect of the automobile is enhanced.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

Detailed Description

In order that those skilled in the art will better understand the technical scheme of the invention, the invention is further described in detail in the following with reference to the accompanying drawings and embodiments;

the utility model provides an prevent parallel light glasses based on pellicle, includes spectacle-frame and gomphosis lens 1 in the spectacle-frame, the front end mirror surface equidistance slope of lens 1 sets up a plurality of semi-permeable membrane lenses 2, semi-permeable membrane lens front end scribbles pellicle 3, pellicle 3 electroplates on semi-permeable membrane lens 2, and the material of pellicle 3 is titanium dioxide; the titanium dioxide has strong adhesive force, is difficult to chemically change and is snow-white forever, meanwhile, the titanium dioxide has better ultraviolet shielding effect and is often used as a sun-screening agent to be doped into textile fibers, and the titanium dioxide has high refractivity and high photoactivity; the refractive power and mechanism thereof are related to the particle size, when the particle size is larger, the light is mainly blocked by reflection and scattering, and the ultraviolet rays in a medium wave region and a long wave region are effective,

the inclination angle of the semi-permeable membrane lenses 2 is 35-55 degrees, and the vertical distance of the semi-permeable membrane lenses 2 which are arranged at intervals is smaller than the vertical height of the inclined semi-permeable membrane lenses 2; the semi-permeable lens 2 is adhered to the front end mirror surface of the lens 1; the inclination angle of the semi-permeable membrane lenses 2 is 35-55 degrees, so that under the premise of ensuring the normal use of the original lenses, a proper amount of refraction is realized, and the normal use of the glasses is ensured, and the vertical distance between the semi-permeable membrane lenses 2 which are arranged at intervals is smaller than the vertical height of the inclined semi-permeable membrane lenses 2, so that the semi-permeable membrane lenses 2 can completely cover the lenses 1, and the light-shading effect is ensured;

the semi-transparent principle glass has the transmittance of about 96 percent, achieves the semi-transparent effect by increasing reflection and reducing transmission, and is characterized in that a medium with the refractive index of n1 is coated on a glass plate, and the reflectivity R1 [ (n0-n1^2/ng)/(n0+ n1^2/ng) ] ^ 2; n0 is the refractive index of air, n2 is the refractive index of glass, the reflectance increases as the refractive index of the film increases, and the single-layer film is made of titanium dioxide (n1 is 2.45) having a high refractive index.

The mounting method comprises coating film on glass by electroplating, embedding several glass sheets coated with film into the front lens, and bonding the front lens and the rear polarizer.

Because the high beam emits parallel light, the high beam is parallel to the ground, and the height of the high beam is approximate to the height of the eyes of the opposite automobile driver; after light passes through the pellicle, 50% light is reflected, and 50% sees through the pellicle, gets into driver's eyes, and the light intensity that driver's eyes received like this reduces half, has alleviateed the problem of dazzling greatly, and on 50% light that is reflected then is reflected the road surface in front of the car not far away, the illuminating effect of reinforcing self car.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the invention.
