Problems solved by technology

Although the position of the optical filter of this anti-glare glasses can be considered to be regulated by the mechanical structure, it is still inconvenient to adjust during the driver's driving. Existing problems; if adjusted, there will be a great hidden danger to the driver's driving safety
Moreover, this adjustment sometimes needs to be very frequent, which is even more inconvenient.
Above-mentioned two kinds of glasses all can't satisfy driver's needs of dual-use glasses day and night

Embodiment 1

[0034] like figure 1 As shown, this embodiment provides anti-glare glasses, which mainly include a left lens 1 , a right lens 2 and a frame 3 . The left and right eyeglasses are all liquid crystal sheets. Each lens is divided into two regions, taking the left lens 1 as an example, which includes a high-perspective region 1b and a low-perspective region 1a. The low-perspective area 1a is located on the left side, and the low-perspective area 1a corresponds to the direction of the vehicle coming from the opposite left. It is pointed out here that the anti-glare glasses in this embodiment are suitable for countries or regions where vehicles pass on the right side, such as China and the United States.

[0035] When used at night, the light transmittance of the low perspective area 1a can be automatically adjusted according to the distance or brightness of the headlights of the oncoming vehicle. When the brightness of the headlights of the oncoming vehicle is relatively large, t...

Embodiment 2

[0045] The main difference between the anti-glare glasses of the second embodiment and the first embodiment is that the system does not use solar cells, but the same group of button batteries are used for power supply in both daytime and nighttime modes. Day mode and night mode each have their own dedicated photodiodes or photoresistors as their respective illuminance sensors and oncoming vehicle light detectors. like Figure 5 shown. A toggle switch directs power to either day mode or night mode. In daytime mode, the entire lens is controlled by photoresistor, daytime illuminance comparator, and square wave generator; in night mode, the low perspective area of ​​the lens is controlled by photodiode, nighttime illuminance comparator, and square wave generator. The structure of the lens and the principle of the specific control circuit are the same as those in the first embodiment, and will not be repeated here.

[0046] In the first and second embodiments above, the lens h...

Abstract

The invention relates to a type of liquid crystal glasses, especially to a type of day and night anti-dazzle liquid crystal glasses for drivers. By the use of the glasses, dazzle interference caused by sunlight can be prevented at daytime, and interference of lamplight from a vehicle headed in the opposite direction with the vision of a driver in another vehicle can be prevented at night. The glasses contain spectacle frame (3), a right lens (2) and a left lens (1). The right lens and the left lens respectively have at least one high-perspectivity area and at least one low-perspectivity area. Two ends of the high-perspectivity area and the low-perspectivity area are respectively provided with electrodes. The glasses also contain a solar cell, a button cell, at least one oppositely-driving vehicle lamplight detector (4), a control circuit and a manual switch. The solar cell is used for an illuminance sensor and is also a power supply of the day anti-dazzle glasses. The button cell is used as a power supply of the night anti-dazzle glasses. The control circuit contains an illuminance comparator and a square-wave generator. The manual switch is used for switching day and night two application function modes and corresponding circuit structures. The glasses provided by the invention can have an anti-dazzle function and also can increase visual comfort level of drivers.

Description

technical field [0001] The present invention relates to a kind of driver's special spectacles for daytime and nighttime, in particular to a kind of anti-dazzling spectacles which are made of liquid crystal sheet to prevent the sunlight from dazzling in the daytime and to prevent the oncoming lights from interfering with the driver's vision at night. Background technique [0002] Anyone who drives knows that when driving in the sun during the day, the sunlight or the reflection of the road surface outside the car will irritate and disturb the driver's eyes; ), the visual interference to the driver is very obvious, and it is even impossible to see the road ahead. Both of these situations will cause the driver's visual fatigue, and there is a great potential safety hazard. For preventing above-mentioned situation from happening, the research of all kinds of anti-glare glasses at night also increases gradually. Typical anti-glare glasses are as described in the CN88220466.1 do...
