Features:
1. Because LED Tunnel Lighting's CRI can reach 80 and above, close to natural light. Therefore at day, car pass through tunnel, driver can quickly accept light color change, very advantage for travel safety.
2. LED Tunnel Lighting don't has "operating time" problem, can immediate work after on. It is convenient to realize Intelligent Power Saving Control, such as diagram below:

This controlling solution is compose of Car Detector which install at tunnel entrace and exit, PLC Power Controller. When no car is travel to this tunnel, PLC Power Controller will cut off tunnel power, in order to reduce electicity waste. When car approach to this tunnel, Car Detector transmit car Pass trough information to PLC Power Controller, PLC Controller provide power to tunnel lighting system in advance. After car safely pass though tunnel, controller again cut off power input, effectively avoid electricity waste, save operating cost.

Applying this solution, day can save 10%, night can save 30%, at the same time can enlong lamp using lifespan. Very suitable apply totunnel lighting system.
