Patent ID: 8547022

Claim:
A lighting control system comprising: a plurality of luminaires powerable and controllable by a common AC power source, each of said luminaires having at least one selectively powerable HID lamp, at least one selectively powerable LED light source; HID electronics electrically connected to said HID lamp and selectively electrically connected to said AC power source; LED electronics electrically connected to said LED light source and selectively electrically connected to said AC power source; and a signal receiving controller electrically connected to said HID electronics and said LED electronics, said signal receiving controller having a power source input selectively electrically connected to said AC power source; wherein each said signal receiving controller selectively causes said AC power source input to be supplied to either said HID electronics or said LED electronics; a lighting controller electrically coupled with said AC power source remote from said plurality of luminaires; wherein said lighting controller is configured to pulsingly decrease and increase the voltage between said AC power source and said power source input of said signal receiving controller of a plurality of said luminaires, thereby causing a control pulse signal to be generated at said power source input of each said signal receiving controller of a plurality of said luminaires; and wherein said signal receiving controller of each of said luminaires is configured to recognize said control pulse signal at said power source input and after recognition of said control pulse signal to cause an alternate of said HID electronics and said LED electronics to be routed with said AC power source input.
