Abstract
The utility model provides colour changeable glasses, comprising glasses frames and lenses which are arranged in the glasses frames. The colour changeable glasses are provided with a photoelectric conversion device, the lenses are made of liquid crystal sheets, and the photoelectric conversion device is connected with the liquid crystal lenses through control circuits. The colour changeable glasses have the advantages that while in use, the colours of the lenses of the colour changeable glasses can be changed quickly, and consequently, the eyes of a user can be effectively protected; the colours of the lenses has greater changeable range, so that the colour changeable glasses are suitable for using under intense light.
Description
Technical field
The utility model relates to a kind of light-sensitive sunglasses.
Background technology
Existing light-sensitive sunglasses mainly are made up of picture frame and the color-changing lens that is arranged in the picture frame; when making color-changing lens; normally in glass for lenses, add to meet the chemical substance of changeable colour behind the light; thereby make this color-changing lens under the sunlight of different brightness, produce different colors, reach the effect that the protection eyes are not subjected to the sunlight injury with this.This light-sensitive sunglasses mainly have the following disadvantages: because this color-changing lens is realized the variable color process by chemical method, therefore, the variable color speed of eyeglass is slower.When sunlight was undergone mutation, eyeglass is variable color immediately, thereby can not protect user's eyes effectively.Simultaneously, the variable color amplitude of this glasses is also less usually, often can not play a very good protection for special forceful rays.
Summary of the invention
The purpose of this utility model is to provide a kind of can make the rapid variable color of eyeglass, and can effectively protect the light-sensitive sunglasses of user's eyes.
For realizing the purpose of this utility model, a kind of light-sensitive sunglasses comprise picture frame and are arranged on the interior eyeglass of picture frame that described light-sensitive sunglasses are provided with photoelectric conversion device, and eyeglass adopts LCD panel to make, and photoelectric conversion device is connected with liquid crystal lens by control circuit.
The utility model has the advantages that: during use, the rapidly variable color of the eyeglass of these light-sensitive sunglasses, thus can protect user's eyes effectively; And the variable color amplitude of color-changing lens is bigger, is adapted at using under the high light.

Embodiment
As shown in Figure 1, 2, a kind of light-sensitive sunglasses, comprise picture frame 1 and two eyeglasses 2 that are arranged in the picture frame 1, two eyeglasses 2 all adopt LCD panel to make, photoelectric conversion device 3 is connected with two liquid crystal lens 2 by control circuit 4, and photoelectric conversion device 3 and control circuit 4 are arranged on the picture frame 1 between two eyeglasses 2.
As shown in Figure 3, described control circuit 4 comprises resistance 5 and variable resistor 6, and eyeglass 2 is concatenated into the loop by lead 7 and photoelectric conversion device 3, and resistance 5 and variable resistor 6 difference parallel connections are between two leads 7.
When light-sensitive sunglasses of the present utility model use, when irradiate light to photoelectric conversion device 3, photoelectric conversion device 3 can become electric energy with transform light energy automatically, and voltage is added on the liquid crystal lens 2 by the lead in the control circuit 47, thereby make liquid crystal lens 2 variable colors, light is strong more, and the electric current of generation is big more, and the degree of liquid crystal color-changing is also big more.Because opto-electronic conversion and conduction of current speed are fast, therefore, these light-sensitive sunglasses can use applicable to industries such as electric welding operations at instant color-changing.
In the above-described embodiments, eyeglass 2 also can adopt the liquid crystal of a monoblock to make, and also can adopt two blocks of liquid crystal to make.Photoelectric conversion device 3 can be arranged on the picture frame 1 usually, also can be arranged on the eyeglass 2.
