Method and System for Luminance Characterization
First Claim
1. A method comprising:
- detecting a triggering event;
identifying an operating parameter of a streetlight;
identifying a different operating parameter associated with the triggering event; and
controlling one or more switches selectively to generate a control signal corresponding to the different operating parameter, the control signal configured to control the streetlight while the streetlight is enabled.

Abstract
A system for luminance characterization of a luminaire includes a ballast coil and a multi-tap capacitor connected in series with the ballast coil. The multi-tap capacitor has a plurality of tap capacitors integrated into a capacitor housing. A plurality of switches are each coupled to one of the plurality of tap capacitors for selectively coupling the tap capacitors together to produce a multi-tap capacitance corresponding to a configuration of the plurality of switches. A lamp is connected in series with the multi-tap capacitor and the ballast coil. A photometer is located to measure light intensity of the lamp and to produce a lumen output measurement. A memory is used to store a database having a plurality of lumen output measurements, each corresponding to a multi-tap capacitance corresponding to all configurations of the plurality of switches.

18. A system comprising:
-
a streetlight; and a controller configured to; identify a schedule associated with controlling the streetlight, the schedule including a plurality of scheduled events each corresponding to a different scheduled brightness level; control the streetlight to operate at a first brightness level; control the streetlight to operate at a first scheduled brightness level different from the first brightness level upon detecting a first scheduled event associated with the first scheduled brightness level; monitor a lighting parameter associated with the first scheduled brightness level; and control the streetlight to operate at a second brightness level different from the first scheduled brightness level until the lighting parameter reaches a predetermined level. - View Dependent Claims (19, 20, 21, 22)
