基于液晶电光效应的智能调光玻璃装置

摘要

In order to realize the adjustment of indoor light , according to the photosensitive resistance , adjustable precision potentiometer and liquid crystal electro‐optic effect experimental principle , a kind of intelligent tunable glass was designed , which has carried on the theoretical analysis and experimental verification .In the automatic mode control circuit , when the outdoor light changed , the photosensitive resistance was changed with the light ,then the voltage across the LCD glass was changed by the control circuit ,the goal was reached that the light intensity behind the glasses was controlled within an appropriate range .In the manual mode control circuit ,the light intensity behind the glass was continuously changed by using the adjustable precision potentiometer .Test results show that this kind of design scheme of intelligent tunable glass could control the light intensity within a certain range when the light intensity is changed ,and continuously adjust the light intensity behind the glass .%为了实现对室内光强的调节，根据光敏电阻、可调精密电位器以及液晶电光效应原理，设计了一种智能调光玻璃，并进行了理论分析和实验验证。在自动模式控制电路下，当室外光强改变时，光敏电阻的阻值随光强改变，进而通过控制电路改变液晶两端的电压，达到将玻璃后的光强控制在一个合适的光强范围内的目的；在手动模式控制电路下，通过精密可调电位器连续地改变玻璃后的光强。测试结果表明，这种智能调光玻璃的设计方案，可在光强变化时把光强控制在一定范围内，并能连续调节玻璃后的光强。
