At the heart of this technology, a new generation of high-brightness light-emitting diodes. Very simply, if the LED is ON, user can transmit a digital string of 1, if it’s OFF then user can transmit a string of 0. It can be switched ON and OFF very quickly, which gives instant opportunity for transmitting data. It is possible to encode data in the light by varying the rate at which the LEDs flicker ON and OFF to pass different strings of 1s and 0s. The modulation is so fast that the human eye doesn’t notice. There are over 14 billion light bulbs used across the world, which needs to be replaced with LEDs ones that transmit data.

Working Principle:
The light intensity can be manipulated to send data by tiny changes in amplitude. This technology uses visible spectrum of light ,a part of the electromagnetic spectrum that is still not greatly utilized. In fact the technology transfers thousands of streams of data simultaneously, in parallel, in higher speeds with the help of special modulation, using a unique signal processing technology.
As shown in the above block diagram,
It consist of transmitter section and receiving section. Here by means of light we are transmitting streams of data. The Transmitter section transmit the data that we type from our pc through LED.This LED can transmit data serially at the baud rate 38400. This data is received serially by the receiver section and that data is displayed in the receiver section PC through serial to USB. The data is received only when receiver section is in the range of transmitter section as a result this system is highly secure.
