Abstract:
A time delay power controller for use in controlling a plurality of high intensity discharge lamps, said controller comprising:a power input for receiving alternating electrical power from an external source;a timer activation device connected in parallel to one or more timers, each timer having an associated delay time and an output for delivering power after the delay time has elapsed; anda plurality of contactors, with a first contactor of said plurality of contactors coupled to the timer activation device and each remaining contactor coupled to the output of a respective one of said timers and each contactor coupled to one or more associated high intensity discharge lighting circuits, the first contactor allowing delivery of alternating electrical power to its associated high intensity discharge lighting circuits when the timer activation device is enabled and each remaining contactor allowing delivery of alternating electrical power to its associated high intensity discharge lighting circuit when the delay time of the respective one of the timers has elapsed.
