1. A lighting control system comprising:
- a plurality of lighting devices arranged along a road for a moving body, wherein each of the lighting devices includesa light source that emits light,a sensor that detects the moving body,a control unit provided with a detection result of the sensor, anda communication unit that sends and receives the detection result of the sensor to and from the communication unit of at least one of the other lighting devices,wherein when the control unit of each lighting device receives the detection result indicating the detection of the moving body, the control unit controls the light source to be in a bright state and sends the detection result indicating the detection of the moving body from the corresponding communication unit to at least one of the other lighting devices,when the control unit of each lighting device receives the detection result indicating the detection of the moving body through the corresponding communication unit from another one of the lighting devices, the control unit controls the corresponding light source to be in a bright state, andthe sensor of the one of the lighting devices located in at least at one outermost position of the lighting devices is set to have a higher detection frequency than the sensors of the other lighting devices.

Abstract
A lighting control system includes lighting devices arranged along a road for a moving body. Each lighting device includes a sensor that detects a moving body approaching the lighting device, a light source that emits light, a sensor that detects the moving body, a control unit connected to the sensor and the light source, and a communication unit. The sensor of the one of the lighting devices located in at least at one outermost position of the lighting devices has a higher detection frequency than the sensors of the other lighting devices.
