The document discusses how LEDs can be used to transmit data. LEDs connected to a transmitter can be switched on and off very quickly to transmit binary 1s and 0s, which are detected by a light sensor at a receiver. By modulating the intensity of many small LEDs too quickly for the human eye to detect, data can be transmitted through lighting without being visible. Dividing a lighting area into many thousands of small LED elements allows transmitting data through lighting.
8. PROCESS
LED is connected to the transmitter and light senso
to the receiver. LED, photo detector registers a bina
¡®1¡¯ for ON else its ¡®0¡¯ for OFF. The LED¡¯S can be
switched ON and OFF very quickly which gives nic
opportunities for transmitting data. LED is light
illuminating Device and its intensity can modulate in
a way that indictable to the human eye. The basic
idea by ganging together many small light source
rather than one light source we still have capability
to do lightning. We are dividing active area into ma
thousands of much smaller elements and these
individual elements that we called micro -
