LED flood light dimming technology and future development
Improve the intelligent control should have manual control, intelligent control, light control, time control and fault alarm. When the sun goes down the sky gradually dim light can automatically light at midnight 12 lights can be automatically halved; dawn, the light can be automatically extinguished; in exceptional circumstances, people can manually control; control and failure, the control system automatically Call the police.
Intelligent dimming system includes server, the central controller, monolithic controller and signal detection circuit 4 copies.
Server: Host and computer software, the main monitoring and alarm functions. Website Server The connection between the street light management control center and the central controller can be achived via powerline carrier, network or wireless.
Central Controller: Responsible for receiving signals from the server and sending them to the controller, control and signal detection, while sending the results to the server's decoding unit.
Signal detection circuit, detection of ambient light, drive power supply voltage, current. And the detected signal is sent to the cell controller or the central controller.
Unit Controller: Each LED lamp is equipped with a unit controller that receives the command by the central controller to control the light or turn the LED on and off, and at the same time the LED is controlled by the drive voltage and current signals to the central controller of the circuit. When the existing LED lamp failure to the fault signal to the central controller.
Currently in the field of road lighting, LED applications are rapidly spread, long life and reliability is still considered the first thing to do, but with the development of technology, when the life and reliability issues are resolved, to some extent, LED lighting applications will inevitably move toward intelligent dimming system.
