LUMINAIRE WITH ATMOSPHERIC ELECTRICAL ACTIVITY DETECTION AND VISUAL ALERT CAPABILITIES
First Claim
1. A system to visually warn of atmospheric electrical activity, the system comprising:
- a housing; and
a control subsystem including;
at least one atmospheric electrical activity sensor that produces a sensor signal responsive to an occurrence of atmospheric electrical activity, the sensor signal including at least one aspect representative of sensed atmospheric electrical activity;
a nontransitory storage media to store at least one of machine executable instructions or data; and
at least one controller communicatively coupled to the at least one atmospheric electrical activity sensor, communicatively coupled to the nontransitory storage media, and communicatively coupled to a lighting subsystem, the controller responsive to the sensor signal to selectively interrupt a first state of the lighting subsystem, in which a luminous output of the lighting subsystem is controlled responsive to at least one of a detected solar event or a expected solar event, with a second state.

Abstract
An illumination system can provide at least a first state and a second state of a luminaire equipped with at least one lighting subsystem. In the first state, the luminous intensity of the lighting subsystem is controlled based on the occurrence of a detected solar event or the occurrence of an expected solar event. In the second state, the luminous intensity of the lighting subsystem forms a visually distinct pattern based on the detection of atmospheric electrical activity exceeding a defined threshold by an electrical activity sensor disposed within the luminaire. The visually distinctive luminous output can alert persons within line of sight of the luminaire of the proximity of threatening atmospheric electrical activity.

20. A method of operating a luminaire to provide a visual indication of atmospheric electrical activity, the method comprising:
-
generating by a control subsystem one or more signals that place a lighting subsystem in a first state in which a luminous output of the lighting subsystem is controlled responsive to at least one of a detected solar event or a expected solar event; responsive to the occurrence of an atmospheric electrical event generating a sensor signal by at least one atmospheric electrical activity sensor, the sensor signal including data representative of at least one aspect of the atmospheric electrical event; determining by the control subsystem whether the data representative of at least one aspect of the atmospheric electrical event in the sensor signal has exceeded a respective defined threshold; and responsive to the determination that at least one aspect of the sensor signal exceeds a defined threshold, interrupting the first state and placing the lighting subsystem in a second state by the at least one control subsystem. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
