PROBLEM TO BE SOLVED: To provide a visible light communication system using an optical duct.SOLUTION: According to the present invention, a visible light communication system using an optical duct introduces natural light into the inside of a building. The visible light communication system includes: an optical duct having a plurality of light emitting sections formed; and a visible light transmitter for emitting communication light for visible light communication toward an inner wall surface of the optical duct. In the visible light communication system of the present invention, an optical axis direction of the visible light transmitter is positioned so that the communication light that has entered the light emitting sections passes through the light emitting sections and also is reflected by the light emitting sections.SELECTED DRAWING: Figure 2 【課題】本発明は、光ダクトを利用した可視光通信システムを提供することを目的とする。【解決手段】本発明によれば、建物の屋内に自然光を導入するための光ダクトを利用した可視光通信システムであって、複数の放光部が形成される光ダクトと、可視光通信の通信光を前記光ダクトの内壁面に向けて出射する可視光送信機とを含む、可視光通信システムが提供される。本発明の可視光通信システムでは、前記可視光送信機の光軸方向は、各前記放光部に入射した前記通信光が、該放光部を透過し、且つ、該放光部で反射するように位置決めされる。【選択図】図２
