Abstract

A device and method to automatically control timing of outside lighting are achieved. An ephemeris program and a calendar are loaded into memory on a timing device. Power is applied to the device wherein a GPS circuit on the device is energized, and Greenwich Mean Time (GMT), Current Day (CD), and physical location of the device are determined from satellite signals through an antenna or alternately from a repeater circuit or a key fob type device. GMT and CD that are retrieved are stored in memory. Lighting on and off times are calculated by the ephemeris program based on physical location, the calendar, GMT, CD, and the user selected distance of the sun below the horizon. Lights are turned on and off based on the calculated on and off times.

a memory for storing Greenwich Mean Time (GMT) and Current Day (CD), and a program to calculate lighting on and off times based on said device'"'"'s physical location, said GMT and CD, and on the ephemeris movement of the sun relative to said device'"'"'s physical location on the earth;

a processor to run said program; and

a relay to turn lights on and off based on calculated said on and off times.

2. The device according to claim 1 further comprising a power supply and an antenna wherein upon application of power to said device through said power supply at installation time, said GPS circuit is energized and said physical location is determined from satellite signals through said antenna.

3. The device according to claim 2 further comprising an indicator LED that is lit if said satellite signals are unavailable.

5. The device according to claim 1 wherein said GMT and CD are loaded into said memory from said GPS circuit or from a computer through a USB port, or wherein said GMT and CD are loaded from an internet-connected portable device onto said device by wireless means, through an input port, or from a key fob type device.

6. The device according to claim 1 further comprising storing in said memory date information for multiple years.

7. The device according to claim 6 further comprising storing in said memory said on and off times calculated by said program for each day from said date information, said GMT and CD, and said physical location.

8. The device according to claim 1 further comprising a LED that is lit whenever said relay is on.

9. The device according to claim 1 further comprising a battery or a photovoltaic cell and capacitor for maintaining said GMT and CD.

10. The device according to claim 1 further comprising dip switches or jumpers wherein said dip switches or jumpers are set at time of manufacture or at a later time wherein said dip switches or jumpers indicate said ephemeris movement of the sun relative to said physical location on the earth and wherein the setting of said dip switches or jumpers determines on and off times at varying degrees of the sun'"'"'s position below the horizon.

11. The device according to claim 10 wherein said dip switches or jumpers are set to 6 degrees at said time of manufacture and wherein said dip switches or jumpers can alternatively be set to 5, 4, or 3 degrees or other degrees that the sun is below the horizon.

12. The device according to claim 1 further comprising a test button to turn on said lighting.

13. The device according to claim 1 further comprising a current sensor to test for bulb failure of said lighting.

14. The device according to claim 13 further comprising a failure send circuit wherein when said current sensor indicates bulb failure, said failure send circuit sends a failure notice.

15. The device according to claim 14 wherein said failure notice further comprises a separate communication device comprising one or more of:

a telephone call;

an email notification; and

a regular mail notification; and

wherein said failure notice includes an identification number for said device and said physical location of said device.

16. The device according to claim 1 wherein said device is a first device and wherein a plurality of said devices are in a line in close proximity to one another, wherein said device includes a repeater wherein said repeater sends said physical location, and said GMT and CD from said first device to the next device in line, and wherein said next device in line sends said physical location and said GMT and CD to the second next device in line, and so on.

17. A method to automatically control timing of outside lighting comprising:

loading a timing program and a calendar into memory on a timing device;

applying power to said device, determining physical location of said device, and storing said physical location in said memory;

retrieving Greenwich Mean Time (GMT) and Current Day (CD) and storing GMT and CD in said memory;

calculating lighting on and off times by said program based on said physical location, said calendar, said GMT, and said CD; and

turning lights on and off based on calculated said on and off times.

18. The method according to claim 17 further comprising maintaining said GMT and CD during power failures with a battery or photovoltaic cell and capacitor.

19. The method according to claim 18 wherein said loading of location, GMT and CD is performed at one or more of:

time of manufacture of said device;

time of installation of said device; and

time of replacement of said battery.
