Beschreibung
Zusammenfassung:	The invention discloses a tunnel lamp based on the visible light communication technology and a communication control method thereof, and relates to the field of LED lighting. A closed-loop communication circuit is formed through the two close-range high-speed wireless communication technologies of visible light communication and infrared communication. The problem that the number of nodes of an RS-485 bus in a tunnel lighting control mode is excessively small for the reasons of drive capability limitation, cable losses and the like can be solved, and the work of manually presetting address codes is further omitted. The communication control method is easy and convenient to operate and low in cost. Data can be uploaded to a remote management platform through a master controller, and the lighting effect can be adjusted automatically according to the brightness outside a tunnel. 种基于可见光通信技术的隧道灯及其通信控制方法涉及LED照明领域。其利用可见光通信和红外通信两种近距离下的高速无线通信技术，通过形成个闭环通信回路。改善RS-485总线在隧道照明控制因驱动能力受限、线缆损耗等原因，致使节点数过少，还省去了需要人工预先设定地址编码的工作。
