Automatic LED Outdoor Lighting achieves by Smart Street Light & Tunnel Lighting using the IoT Lighting Technology which are integrated with Motion Sensor and Ambient Sensor for seamless connecting to get maximum energy optimization. Tunnel Art Lighting with Colorful at the tunnel ceiling or Column-- Prevent the Boring Dring in the Super Long Tunnel on expressway, make the driver more happier driving on the highway, Refresh and relax motorist. 2000+ Tunnels Lighting Projects in China Done(70% of China Marketing Share) 15,560m is the Longest  Freeway Tunnel 16 huge Cities Street Lighting Projects Done, between 5300 ~ 26000 units LED Shen Zhen Banyin Express Freeway Lighting Project adopt Intelligent Lighting Control & Management System, Motion Sensor and Daylight Intensity Sensor Detectors are seamless on the Data sending to the Centralized Controller, simplify operations and management, improve maintenance timeliness, on-demand lighting, energy saving and emission reduction. Tunnel Lighting: 1. Automatic Dimming according to Natural Daylight Intensity detecting Sensor, perfect solution for the Black Tunnel & White Tunnel Effects--Black Tunnel and White Tunnel Syndrome will be completely solvely, especially prevent Vehicle collision or rear-end collision accidents occur at the Tunnel Entrance and the Tunnel Exit area. 2. Linked with the Vehicle Motion Sensor: when a vehicle passes, it is automatically Dimming according to the moving vehilces or people; when there is no vehicle passes, it returns to a safe illuminance. Street Lighting: 1. Automatically Turn on & off the lamp according to the Sunset and Sunrise. 2. Automatically Dimming according to the Set Scene Timing. 3. Automatic Dimming according to Natural Light Intensity, automatic Turn On and Emergency Lighting in abnormal weather (such as Heavy Cloudy Weather, Heavy Rain, etc.). The System integrates Lamp Control Module, Expert Analysis Module, Energy Consumption Monitoring Module, Emergency Module, fully demonstrates the advanced technology and scheme of the system.

Automatic LED Outdoor Lighting achieves by Smart Street Light & Tunnel Lighting using the IoT Lighting Technology which are integrated with Motion Sensor and Ambient Sensor for seamless connecting to get maximum energy optimization. Automatic Dimming according to Natural Daylight Intensity detecting Sensor, perfect solution for the Black Tunnel & White Tunnel Effects--Black Tunnel and White Tunnel Syndrome will be completely solvely, especially prevent Vehicle collision or rear-end collision accidents occur at the Tunnel Entrance and the Tunnel Exit area. Some old Tunnels with long years HPS lighting service, but a rather dark brightness because of Light Attenuation. Lower buget owner can save big investment volume by choosing the 485 Solution. There is also PLC -- Power Line Communication Single Lamp Controller, but there is a shortadvange, once any of the lamp is failure,  the maintanence meet a critical problem to repair it by shut off the whole group's power. A better solution can be choosed is the Loop Circult Control Solution. All of the above solutions have been widely using  in our different 2000 Tunnels in the past 8 years. Tunnel length from 300m/500m ~ 2km/5km or 7/8km~15.6km. PLC & LoRa Hybrid Solution on the Highway Road Lighting/Street Lighting Projects
