Patent ID: 8896215

Claim:
A luminaire, comprising: at least one light source; and a control subsystem to control a supply of power to the at least one light source, the control subsystem including: at least one timing circuit to provide a timing signal; at least one nontransitory storage media to store geolocation information that specifies at least a position on the Earth at which the luminaire is to operate; a controller communicably coupled to the at least one timing circuit and the at least one nontransitory storage media, and that: determines using at least the store geolocation information, at least one aspect of a scheduled solar event at the postion on Earth at which the luminaire is to operate; and generates at least one output signal having at least one characteristic indicative of the determined at least one aspect of the scheduled solar event; and at least one power controller conductively coupled to the controller, the at least one power controller selectively operable to control a supply of power to the at least one light source responsive to the at least one characteristic of the at least one output signal.
