VISIBLE LIGHT COMMUNICATION SYSTEM

To provide a visible light communication system capable of implementing, inexpensively and without using two optical systems, performance similar to that of a transmitting-receiving shared device of an optical system using a half mirror and the like to share an optical lens, the device having disadvantages from the viewpoint of costs and weight.SOLUTION: A visible light communication system comprising a lens 200, a transmission board 400 including a light emission element 300, and a reception board 600 including a light receiving element 500 performs communication with an external communication target. The receiving element 500 is mounted at a focal position of the lens 200. The transmission board 400 has a transmission board 400 aperture. The light emission element 300 is mounted around the focal position of the lens 200.SELECTED DRAWING: Figure 1 【課題】可視光通信システムにおいて、光学レンズを共通のものとするため、ハーフミラー等を用いた光学系の送受共用装置は、コスト、重量の観点から不利である。光学系を２系統使用せず低コストで同等の性能を実現可能とする可視光通信システムを提供する。【解決手段】可視光通信システムは、レンズ２００、発光素子３００を有する送信基板４００、および、受光素子５００を有する受信基板６００を備え、外部の通信対象と通信を行う。受光素子５００はレンズ２００の焦点位置に実装され、送信基板４００は送信基板４００開口部を有し、発光素子３００はレンズ２００の焦点位置の周囲に実装される。【選択図】図１
