Energy saver for area lights
First Claim
Patent Images
1. A method to save energy, comprising:
- providing an object sensor coupled to a light source;
sensing whether an object is adjacent to the light source;
determining whether a time of day corresponds to a particular start-up time;
determining whether the object includes an active source of illumination; and
illuminating the light source when the time of day corresponds to the particular start-up time, the object is adjacent to the light source, and the object does not include the active source of illumination.

Abstract
Saving energy includes at least one object sensor that is coupled to at least one light sensing if at least one object is present adjacent to the at least one light. If it is further determined that the time of day corresponds to a desired start-up time, the at least one light may then be illuminated by a control system.

4. A method to save energy, comprising:
-
providing an object sensor coupled to a light source, including providing a street light that includes the object sensor; sensing whether the object is adjacent to the light source, including sensing that the object is adjacent to the street light; determining time of day corresponds to a particular start-up time; and illuminating the light source when the time of day corresponds to the particular start-up time and the object is adjacent to the light source, wherein illuminating the light source includes illuminating the street light based on the sensing of the object and the time of day. - View Dependent Claims (5, 6, 7, 8)

9. A system to save energy, comprising:
-
an object sensor, coupled to a street light, that senses a presence of at least one object; a control system, including; a section control system configured to; transmit a signal to activate the object sensor based on a selected time, determine, based on the presence of the at least one object, whether to illuminate an area around the object sensor, and transmit the signal to illuminate a plurality of street lights; and a post control system, associated with the street light and the object sensor, configured to receive the transmitted signal and illuminate the street light. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
