Abstract
A luminaire can comprise a system that automatically adjusts light output from the luminaire to control light level in an illuminated area. The system can increase light output if the light level in the area falls below a target light level or decrease light output if the light level in the area rises above the target. For example, when the area is illuminated by a combination of sunlight and luminaire light, the light level can be maintained at the target level by gradually decreasing light output as the sunlight contribution increases in the morning and by gradually increasing light output as the sunlight contribution decreases in the evening. The system adjustments can take into consideration whether the light level is offset from the target due to a change in the target or a short-term fluctuation that may be due to a cloud temporarily blocking the sun.

21. A system for managing a light source of a luminaire, the system comprising:
-
a microprocessor system that comprises memory and that is connected to a light sensor that comprises a gain; and computer executable instructions stored in the memory for performing the steps of; monitoring light level based on input from the light sensor; changing the gain based on the monitored light level; and adjusting intensity of the light source based on the monitored light level. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A system for managing a light source of a luminaire, the system comprising:
-
a microprocessor system that comprises memory and that is connected to a sensor; and computer executable instructions stored in the memory for performing the steps of; monitoring light level based on input from the sensor; if the luminaire is in a mode and the monitored light level is beyond a threshold for an amount of time, then adjusting intensity of the light source; and if the luminaire is in a different mode and the monitored light level is beyond the threshold, then adjusting intensity of the light source prior to passage of the amount of time. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)

37. A system for managing a light source of a luminaire, the system comprising:
-
a microprocessor system that comprises memory and that is connected to a sensor; and computer executable instructions stored in the memory for performing the steps of; monitoring light level based on input from the sensor; determining whether the monitored light level has undergone a short-term change or a long-term change; and adjusting intensity of the light source based on the determination. - View Dependent Claims (38, 39, 40)
