...光通讯(Visible Light Communication, VLC)。 Li-Fi 光通讯利用 LED 灯泡做为讯号的发射器,并装设光电二极体(photodiode)作为接收器,当灯泡亮起即代表 1,熄灭代表 0,借由光线编码并传输资讯。由于灯泡闪烁速度极快,人类肉眼并无法察觉其变化。

请参照图七a,具有个别微透镜元件710 - A之微透镜阵列可用以将光线聚焦在光电二极体上。
Referring to Figure 7a, a micro-lens array having an array of individual lens elements 710-a May be used to focus light into the photodiodes.
第一种方式是透过光电二极体上的光源减少来对电容器进行放电,一旦所需的光源输出被产生之后就关闭装置。
The first USES the light falling on the photodiode to discharge the capacitor, turning off the device once the required light output has been generated.
