A new intelligent lighting system based on adaptive neighborhood algorithm using correlation coefficient(ANA/CC) is proposed, which uses the new visible light communication(VLC) technology for direct communication between the lighting fixture and the illuminance sensor to supply illuminance for the special spot.

This research proposes a new intelligent lighting system based on ANA/CC(Adaptive Neighborhood Algorithm using Correlation Coefficient),and uses the new Visible Light Communication(VLC) technology for the direct communication between the lighting fixtures and the illuminance sensors.

This channel can be applied to video communication.

With the promotion of Visual Communication business based on broadband, more and more people would like to use it.

The paper introduces common schemes of terminals used in visual communication nowadays at the first.

The visible-light communication utilizing the white LEDs is a kind of optical wireless communication characterized by high emission power rate,spreading everywhere,electromagnet free interference and energy-saving,etc.

As a potential technology for high-speed indoor wireless networks,visible-light communication still needs to overcome the penalties of background-light noise and the multipath effect.

The current situation and development trend of indoor visible light communication by white LED illumination

The visible light communication(VLC) is a kind of optical wireless communication that uses the white LEDs.

Thanks to the white LED s excellent properties such as low power consumption, long lifetime, high reliability and short response time, it is possible to upgrade the indoor white LED illumination source to a wireless optical communication system In this thesis, we analysised the current visible light communication system and discussed the key t.
