Sound intelligent control should have manual control, intelligent control, light control, time control and fault alarm control functions. When the sun goes down and the sky darkening，the LED light especially the sensor LED flood light automatically lit and the lamp illumination can automatically halved after midnight; the sensor LED flood light and other LED light don’t automatically turns off until dawn ; which can manually control under special circumstances; while the lamp fails, the control system can automatically alarm .
Intelligent dimming system consists of servers, the central controller , single-chip controller and signal detection circuit composed of four parts .
Server: composed of the host computer and the host computer software, the main achievement monitoring operation and alarm functions. The server is located in street management and other control center , and its links with the central controller can use the power line carrier , network or wireless .
Central Controller: responsible for receiving signals sent from the server , and decode and send to the unit controller to achieve control, while the signal detection results are sent to the server.
Signal detection circuit : detects the environmental brightness , drive power supply voltage and current. And send the resultant detection signal to the unit controller or a central controller .
Unit controller : Each LED lights especially the sensor LED flood light is equipped with one unit controller , by receiving commands of the central controller is to dim the sensor LED flood light and other LED light or control on and off , while sending the driving voltage , the current of LED lamp to the central controller through the signal detection circuit. When the sensor LED lamp failure， the fault signal is sent to the central controller.
LED applications are currently rapidly growing popularity in the field of road lighting, long life and reliability is still the first factor to consider , but with the development of technology , when the life and reliability of the problem have been resolved to a certain extent , sensor LED flood light and road LED lighting applications inevitably strides towards intelligent dimming system.Taking a good look at http://www.lead-lighting.com/led-flood-light/high-power-waterproof-pir-led-flood-light-series.htm for detailed description of the awesome but affordable sensor LED flood light.
