Visible Light Communication (VLC) system employ visible light for wireless communication that occupy the spectrum ranging from 380 nanometer to 750 nanometer. The paper describes an application of the Visible Light Communication (VLC) in museums. VLC technology is used for giving information about different monuments in the museum. This approach to convey information aims to replace current methods of delivering information using a MP3 player and other wireless technologies such as Bluetooth or RF. The optical source, LEDs perform two functions, illumination and transmission, simultaneously and is connected over the monuments. An audio information signal is used as a modulation signal to vary the intensity of light emitted by the optical sources. This audio signal contains the factual information related to the monuments. The receiver modules are connected to headphones. The modulated optical signal is sensed at photosensitive target and is demodulated at the receiver end. In this way, the factual information related to the monument is conveyed to the visitors.
