Description

Electrochromic glass light transmission consistency control device based on photoresistor

Technical Field

The utility model relates to an electrochromic glass technical field, concretely relates to electrochromic glass light transmission uniformity controlling means based on photo resistance.

Background

The electrochromic glass or electrochromic device is a device formed by utilizing the electrochromic effect of substances, taking an electrochromic layer as a base and assisting other related layers and structures, and has the unique advantages of wide viewing angle, low driving voltage, no power consumption memory and the like.

The typical structure of the electrochromic device is a glass substrate, a transparent conducting layer, an electrochromic layer, an ion conductor layer, an ion storage layer, a transparent conducting layer and a glass substrate from top to bottom respectively. Electrochromic devices that have been commercialized fall into the following categories: electrochromic intelligent dimming glass, electrochromic display and automatic anti-dazzling rearview mirror of automobile.

The working principle of the photoresistor is based on the internal photoelectric effect. Electrode leads are arranged at two ends of a semiconductor photosensitive material and are packaged in a tube shell with a transparent window to form the photosensitive resistor, and in order to increase the sensitivity, the two electrodes are usually made into a comb shape. The materials used to fabricate the photoresistor are mainly semiconductors such as metal sulfides, selenides, and tellurides. Usually, the method of coating, spraying and sintering is used to make a very thin photosensitive resistor and comb-shaped ohmic electrode on an insulating substrate, and lead wires are connected to be packaged in a sealed shell with a light-transmitting mirror so as to prevent the sensitivity from being affected by moisture. After the incident light disappears, the electron-hole pairs generated by the photon excitation are recombined, and the resistance value of the photoresistor is restored to the original value. Voltage is applied to the metal electrodes at two ends of the photoresistor, current passes through the photoresistor, and when the photoresistor is irradiated by light with a certain wavelength, the current is increased along with the increase of light intensity, so that photoelectric conversion is realized. The photoresistor has no polarity, is a pure resistor device, and can be applied with direct current voltage and alternating current voltage when in use. The conductivity of a semiconductor depends on the number of carriers in the conduction band of the semiconductor. According to the spectral characteristics of the photoresistor, three types of photoresistors can be classified: ultraviolet light-sensitive resistor, infrared light-sensitive resistor, visible light-sensitive resistor.

Due to the difference of the illumination intensity and the illumination angle, the illumination intensity distribution of the light after the light penetrates through the electrochromic glass is not uniform.

The electrochromic glass and the common glass arranged in parallel form an intelligent curtain wall.

The working principle of the utility model is as follows.

Electrochromic glass is located the outside of intelligent curtain for block heat gets into, so the photo resistance is installed in the cavity layer, detects the illumination intensity after seeing through electrochromic glass, and this illumination intensity and photo resistance directly can have a fixed relation curve. Every intelligence curtain all can a photo resistance of interior installation, and each photo resistance all passes through the wire with the controller that discolours and is connected. The color-changing controller reads the value of the photoresistor and then obtains the current illumination intensity through the prestored graph of the illumination intensity and the photoresistance value. The color-changing controller adjusts the light transmittance of each electrochromic glass according to the comparison result by comparing the value with the set value, thereby achieving closed-loop feedback adjustment, stabilizing the light transmittance at or near the set value, and enabling all the electrochromic glasses of the same curtain wall to have the same set value, so that the light transmittances of all the electrochromic glasses of the same curtain wall are consistent or basically consistent finally; in the utility model, one side of the light incidence is "inner" and one side of the light emergence is "outer".

The curve relation between the illumination intensity and the photosensitive resistance value is a known technology, the voltage of the electrochromic glass is adjusted by comparing the measured illumination intensity with a set value, and then the light transmittance of the electrochromic glass is adjusted, and the method belongs to the field of the prior art and is a common technical means for technicians in the field.

As shown in fig. 3, the photoresistor is connected to the color-changing controller through two wires (interface 1); the electrochromic glass leads out a positive and negative wire (interface 2) to be connected with a color-changing controller for color-changing control. The interface 1 and the interface 2 are convenient to be butted with the color-changing controller.
