Abstract

A lot of research has focussed on LED lights to move technology forward in the visible light communication field. Due to their properties which include high efficiency, high luminance, reliability, long life tune, low energy consumption and cost savings, white light LEDs are expected to be the next generation of lamp and communication systems. White light LEDs have dual functions; they illuminate rooms and have applications in optical wireless communication systems. In this study, the fundamental experiment was carried out to study the ability of white LEDs to be used as the transmitter with a photocell as the receiver. The LED worked as the transmitter and transmitted the modulated audio signal via open space to the receiver. The photocell worked as the transducer and once it was connected to the amplified speaker, the original audio signal could be heard. The results from these experiments showed that high frequency could enhance the ability of white LEDs to be used for data transmission with the ability to hear the output audio signal up to 50 cm from the transmitter to the receiver.
