ABSTRACT:
A systemic method to control fluorescent and/or incandescent lighting fixtures located in or on an above ground, enclosed or partially enclosed, parking structure uniquely employing previously patented components whereby the existing lighting fixtures of an above ground, enclosed or partially enclosed parking structure are reconfigured and rewired to accommodate a zonal, sensored lighting control system. A remote sensing unit is employed at predetermined spacing locations utilized to detect vehicular and human body movement across the sensed thresholds and to detect infrared emissions from the same sources to initiate the switching units thereby energizing the zoned lighting fixtures. Also employing included photoelectric controls of previously patented detectors to prohibit energy usage of the fixtures during the daylight hours.
