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.
