Bus Announcer System

Manual/Automatic Dimming System

     The LED destination board is equipped with a photosensitive device, which can detect the lighting intensity of its surroundings. (The lighting intensity is divided into 4 levels.) After collecting the information of the lighting intensity, feedback will be given to the control-panel, thus to adjust the lighting level of the LED destination board.

Advantages:
1. The lighting level of the destination board is increased during daytime to highlight the information on it.
2. The lighting level of the destination board is decreased at night.
3. Energy-saving and environmental-friendly.
