Lighting stepless dimming controller
The stepless dimming controller of the lighting can automatically adjust the brightness in the cave according to the brightness outside the cave by receiving the signal from the car detector during the daytime. At night or when the traffic volume is small, the power of the lamps can be reduced synchronously. To minimize lighting energy consumption and achieve energy-saving goals of on-demand lighting.
Product characteristics
System Function：
-
The output voltage circuit is divided into two circuits of basic lighting and enhanced lighting, and each circuit has two outputs
-
The control output 0V corresponds to the maximum brightness of the lamp, and 5V corresponds to the minimum brightness of the lamp; this enables the lamp to work at full power under the fault state, thus ensuring the driving safety
-
The output power of basic lighting can be set at will, the enhanced lighting can change in real time with the brightness outside the tunnel, and the two channels can be continuously dimmed to realize the understanding of lighting on demand
-
There are two RS-485 communication ports, which can communicate with the central control room. The central control room can control the lighting intensity in the tunnel according to the real-time road conditions (such as traffic flow, maintenance, accident, etc.)
-
It can receive the control signal from the vehicle detector, and when there is no vehicle passing, it can adjust the lighting power to the minimum; when there is a vehicle coming, it can adjust the lighting in the tunnel to the required brightness in an instant, and save the electric energy to the maximum extent
-
It is fully compatible with the original system in the electrical circuit
