Electrical circuit cycling controller
First Claim
1. 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; and
a 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.

Abstract
A time delay power controller has a power input for receiving alternating electrical power from an external source; a timer activation device connected in parallel to a one or more timers, each timer having an associated delay time and an output for delivering power after the delay time has elapsed and a plurality of contactors, with a first contactor coupled to the timer activation device and the remaining contactors coupled to the output of a respective timer. Each contactor is coupled to one or more associated circuits. The first contactor allows delivery of alternating electrical power to its associated circuits when the timer activation device is enabled and the remaining contactors allow delivery of alternating electrical power to their associated circuits when the respective timer'"'"'s delay time has elapsed. The controller may be enclosed in a housing. The controller may be configured to sequentially power lighting circuits.

15. A method for activating a plurality of outdoor security lighting circuits in a non-simultaneous manner, said method comprising:
-
(a) supplying alternating electrical power from an external source to a time delay power controller; (b) enabling a timer activation device connected in parallel to a first contactor and to one or more timers, each timer having an associated delay time and an output for delivering power after the delay time has elapsed; (c) initiating said associated delay time upon enabling each timer; and (d) delivering alternating electrical power to one or more high intensity discharge lighting circuits coupled to the output of each timer when the delay time of each timer has elapsed. - View Dependent Claims (16, 17, 18)
