Distributed lighting control of a corridor or open areas
First Claim
1. A method of distributed lighting control, comprising:
- a sensor sensing a change of light intensity per unit of time greater than a sense threshold;
if a light associated with the sensor is within a corridor and the sensed change of light intensity per unit of time is greater than the sense threshold, then activating the light at a preselected corridor light intensity;
if the light associated with the sensor is not within a corridor and the sensed change of light per unit of time is greater than the sense threshold, then activating the light at a preselected non-corridor light intensity.

Abstract
Methods and apparatuses of distributed lighting control are disclosed. One method includes a sensor sensing a change of light intensity per unit of time greater than a sense threshold. If a light associated with the sensor is within a corridor and the sensed change of light intensity per unit of time is greater than the sense threshold, then the light is activated at a preselected corridor light intensity. If the light associated with the sensor is not within a corridor and the sensed change of light per unit of time is greater than the sense threshold, then the light is activated at a preselected non-corridor light intensity. For an embodiment, the preselected corridor light intensity is greater than the preselected non-corridor light intensity.

4. A method of distributed lighting control, comprising:
-
a sensor sensing a change of light intensity per unit of time greater than a sense threshold; if a light associated with the sensor is within a corridor and the sensed change of light intensity per unit of time is greater than the sense threshold, and if within a predetermined amount of time before the sensor sensing a change of light intensity per unit of time greater than a sense threshold, a level light intensity sensed by the sensor is below an initial threshold, then activating the light at a preselected corridor light intensity; if the light associated with the sensor is not within a corridor and the sensed change of light per unit of time is greater than the sense threshold, then activating the light at a preselected non-corridor light intensity, wherein the preselected corridor light intensity is greater than the preselected non-corridor light intensity.
