汽車調光玻璃
Principle of dimming glass: Usually(power off), the internal liquid crystal arranges irregularly and its index of refraction is smaller than the external polymeric substance's, so the incident light scatters on the polymeric substance which makes the glass become milk white, not transparent. While when the dimming glass is electrified, the internal solution in polymeric substance which contains the diffused liquid crystal will rearrange, therefore the liquid crystal will order regularly. In this occasion, the refractive index of the liquid crystal and polymeric substance will be equal, thus the incident light can come through the dimming glass completely which makes it become transparent.
調光玻璃主要用于有保密或隱私防護的場所,由其制成的汽車、機車、軍用車等車窗玻璃就像電磁控制的窗簾一樣,在需要遮蔽視線時斷掉電源,使玻璃處于不透明狀態;在需要采光或透視時合上電源,玻璃就透明了。
The dimming glass is mainly utilized in privacy and secret protection places. And window glass made of these dimming glasses for automobile, locomotive, and military vehicle is just like electromagnetic control curtain, when privacy is needed you can electrify the glass to make it opaque. While when light and sight are needed you can electrify the glass so the glass will be transparent again.
汽車、機車、軍用車等調光玻璃車窗,在停車不使用時是不透明的,竊賊即使打開車門也無法將汽車開走,因為玻璃不透明,竊賊看不到前方的路,此時這種調光玻璃還能起到防盜作用。
And when these dimming glass is used as window for automobile, locomotive, and military vehicle it is opaque when these vehicles are parking. Therefore, even though the door is opened by the thief he/she still cannot steal the car, because he/she cannot see the road. In this occasion, the dimming glass plays an anti-theft role.
