Recently, visible Light Emitting Diode light source has the features, such as high luminescence efficiency, long life and so on. Therefore, LED is also available for next generation optical wireless communication device. Then, our laboratory pay attention to the feature which has high response and have also proposed the application for visible light communication using white LED lights In this research, we propose Visible Light Positioning System. It can simply determine the receiver's position that each white LEDs in a lighting send differential three dimensional space coordinate and a receiver, such as two dimension sensor, receives the signal.
