Abstract

An LED lighting system is disclosed, which generally consists of an enclosure, one or more LED modules, one or more transformers, and one or more drivers. A lamp assembly is disclosed, which generally consists of one or more vertically oriented LED chips, thermally conductive shells, and a thermally dissipating means positioned at the back of the LED chips. An LED module is disclosed, which generally consists of a lamp assembly, one or more reflectors and modules caps. A method of controlling light intensities is disclosed, which generally consists of method of decreasing light intensities in areas with little occupancy while minimizing user annoyance resulting from drastic light intensity fluctuations. A universal mounting bracket is disclosed, which generally consists of a fixture plate, mounting plate, and an adjustable means.

Claims

1. A method for controlling a lighting system comprising:

powering ON a light source, the light source having a high intensity level, an adjustable standby intensity level, and an OFF intensity level, and wherein the adjustable standby intensity level is dimmer than the high intensity level but brighter than the OFF intensity level;

decreasing an intensity of the light source from the high intensity level to the adjustable standby intensity level when a sensor of the lighting system fails to detect a person'"'"'s presence within a predetermined period of time; and

adjusting a light intensity setting of the adjustable standby intensity level based on an amount of human traffic detected by the sensor within one or more periods of time, the light intensity setting controlling a light intensity of the adjustable standby intensity level, wherein the light intensity setting of the adjustable standby intensity level is adjusted for a subsequent utilization of the adjustable standby intensity level.

2. The method of claim 1, further comprising:

incrementally increasing the light intensity setting of the adjustable standby intensity level when a person'"'"'s presence is detected by the sensor before expiration of a timer; and

incrementally decreasing the light intensity setting of the adjustable standby intensity level when a person'"'"'s presence is detected by the sensor after expiration of the timer.

3. The method of claim 1, further comprising:

increasing the intensity of the light source from an initial intensity level to the high intensity level after the sensor detects a person'"'"'s presence; and

starting a first countdown timer after increasing the light source intensity from the initial intensity level to the high intensity level.

4. The method of claim 3, further comprising:

restarting the first countdown timer when the sensor detects a person'"'"'s presence; and

maintaining the intensity at the high intensity level while the first countdown timer is running.

5. The method of claim 3, further comprising:

decreasing the intensity from the high intensity level to the adjustable standby intensity level when the first countdown timer expires without the sensor detecting a person'"'"'s presence; and

starting a second countdown timer after the first countdown timer expires without the sensor detecting a person'"'"'s presence.

6. The method of claim 5, further comprising:

incrementally increasing the light intensity setting of the adjustable standby intensity level when the sensor detects a person'"'"'s presence before the second countdown timer expires.

7. The method of claim 6, further comprising:

increasing the intensity from the adjustable standby intensity level to the high intensity level when the sensor detects a person'"'"'s presence before the second countdown timer expires; and

restarting the first countdown timer.

8. The method of claim 6, further comprising:

incrementally increasing a time duration setting of at least one of the first countdown timer and/or the second countdown timer when the sensor detects a person'"'"'s presence before the second countdown timer expires.

9. The method of claim 5, further comprising:

maintaining the light intensity setting of the adjustable standby intensity level at a maximum value when the sensor detects a person'"'"'s presence before the second countdown timer expires;

increasing the intensity from the adjustable standby intensity level to the maximum intensity level when the sensor detects a person'"'"'s presence before the second countdown timer expires; and

restarting the first countdown timer.

10. The method of claim 5, further comprising:

decreasing the intensity from the adjustable standby intensity level to a low standby intensity level when the second countdown timer expires without the sensor detecting a person'"'"'s presence; and

starting a third countdown timer after the second countdown timer expires without the sensor detecting a person'"'"'s presence.

11. The method of claim 10, further comprising:

incrementally decreasing the light intensity setting of the adjustable standby intensity level when the sensor detects a person'"'"'s presence before the third countdown timer expires.

12. The method of claim 11, further comprising:

increasing the intensity from the low standby intensity level to the high intensity level when the sensor detects a person'"'"'s presence before the third countdown timer expires; and

restarting the first countdown timer.

13. The method of claim 11, further comprising:

incrementally decreasing a time duration setting of at least one of the first countdown timer, the second countdown timer, and/or the third countdown timer when the sensor detects a person'"'"'s presence before the third countdown timer expires.

14. The method of claim 10, further comprising:

maintaining the light intensity setting of the adjustable standby intensity level at a minimum value when the sensor detects a person'"'"'s presence before the third countdown timer expires;

increasing the intensity from the low standby intensity level to the high intensity level when the sensor detects a person'"'"'s presence before the third countdown timer expires; and

restarting the first countdown timer.

15. The method of claim 10, further comprising:

decreasing the intensity from the low standby intensity level to the OFF intensity level when the third countdown timer expires without the sensor detecting a person'"'"'s presence.

16. The method of claim 10, decreasing the intensity from the low standby intensity level to the OFF intensity level when (a) the third countdown timer expires without the sensor detecting a person'"'"'s presence and (b) a determination is made that an end of time period is in effect.

17. A lighting system comprising:

a light source having a high intensity level, an adjustable standby intensity level, and an OFF intensity level, the adjustable standby intensity level being dimmer than the high intensity level and brighter than the OFF intensity level;

a sensor adapted to detect a person'"'"'s presence; and

decrease an intensity of the light source from the high intensity level to the adjustable standby intensity level when the sensor fails to detect a person'"'"'s presence within a predetermined period of time, and

adjust a light intensity setting of the adjustable standby intensity level based on an amount of human traffic detected by the sensor within one or more periods of time, the light intensity setting controlling a light intensity of the adjustable standby intensity level, wherein the light intensity setting of the adjustable standby intensity level is adjusted for a subsequent utilization of the adjustable standby intensity level.
