    • A navigation system and a navigation method inside of a building using Visible Light Communications (VLC) are provided. The navigation system includes a map server, in which map information required to provide a navigation function is stored, for transferring the map information to each lamp, a plurality of lamps, installed in each zone inside of the building and having their respective identifiable and unique IDentifications (IDs), for receiving the map information required to provide the navigation function from the map server, and for generating a visible light signal in response to the received map information by using a VLC module, and a mobile terminal, equipped with a visible light Rx module, for being provided with the map information upon receiving the visible light signal generated from the lamp, and for displaying a map image in response to the provided map information.

    • An optical receiver for visible light communication includes a lens system for converging visible light for light communication and an optical filter for passing converged visible light to the optical receiver. A photoelectric transmission device detects data from visible light for light communication in a VLC system. An optical filter is positioned between the lens system and the photoelectric transmission device, the optical filter having a first film for transmitting visible light and a second film arranged/grown around the first film to transmit ultraviolet rays or infrared rays. A first optical detects data from visible light passing through the first film of the optical filter. A second optical detector detects the intensity of light transmitting the second film. The encoding, encoding rate or intensity of the optical transmitted signal can be adjusted in response to the detection of at least the second optical detector.
    • 用于可见光通信的光接收机包括用于会聚用于光通信的可见光的透镜系统和用于将会聚的可见光传递到光接收器的滤光器。 光电传输装置从VLC系统中的光通信中检测来自可见光的数据。 滤光器位于透镜系统和光电传输装置之间,滤光器具有用于透射可见光的第一膜和布置/生长在第一膜周围的透射紫外线或红外线的第二膜。 第一光学器件检测通过光学滤波器的第一膜的可见光的数据。 第二光学检测器检测透射第二膜的光的强度。 可以响应于至少第二光学检测器的检测来调整光学传输信号的编码,编码速率或强度。
