1. An LED based lighting system for use in highway lighting, comprising:
(a) two or more LED lamps; (b) a master power supply having the capability of converting AC to DC power, the capability of removing harmonics, and energizing a grid with cleaned, high voltage DC power intended supply power to two or more LED lamps; (c) a secondary power supply having the capability of converting AC to DC power, the capability of removing harmonics, and energizing a grid simultaneously with said master power supply with cleaned, high voltage DC power intended supply power to two or more LED lamps, the secondary power supply to be located opposite said master power supply thereby alleviating some of the voltage drop problem that takes place at the end of said master power supply; (d) a master controller with the means for detecting traffic and daylight brightness; the means for communicating bi-directionally and continuously with one or more centralized stations for proper control, checking and reporting of LED light functioning of each LED light independently; the means for issuing commands to each of two or more LED lights independently, the commands including, but not limited to, turning on/off two or more LED lamps independently, dimming up or down two or more LED lamps independently, or checking for lamp failure of two or more LED lamps independently; the means of monitoring the proper functioning of controllers of other LED lighting systems; and the means for taking control of two or more LED lights of other LED systems over master controller of the other LED systems and issues same said commands to other LED lighting systems; (d) a backup controller with the means for detecting traffic and daylight brightness; the means for communicating bi-directionally and continuously with one or more centralized stations for proper control, checking and reporting of LED light functioning of each LED light independently; the means for issuing commands to each of two or more LED lights independently, the commands including, but not limited to, turning on/off two or more LED lamps independently, dimming up or down two or more LED lamps independently, or checking for lamp failure of two or more LED lamps independently; the means of monitoring the proper functioning of said master controller and other master controllers in other LED lighting systems; and the means for taking control of two or more LED lights controlled by said master controller and/or other LED systems and issues same said commands to LED lamps usually controlled by said master controller or to other LED lighting systems; (f) a main pavilion housing said master power supply and said master controller; (g) a secondary pavilion housing said second power supply and said backup controller, located opposite said main pavilion; (h) a DC voltage reducer and controller for each of said LED lamps for reducing DC voltage from power grid and supplying voltage to LED lamp; means for receiving commands from said master and said backup controller; and means for interpreting commands to adjust DC voltage supplied to LED lamp. |
