  • Patent number: 8760072
    Abstract: A high efficiency light emitting diode power supply for roadway lighting fixtures is provided. The power supply enables conditioning and monitoring of input power and monitors LEDs current to ensures consistent performance of the LED by changing a power correction factor. The LED output can also be adjusted based upon age or external input parameters and by modifying the power correction factor value. In addition, the LED output can be dimmed, turned down in output to a lower level at any time of night for a prescribed duration in order to further save energy. This dimming function uses a programming scheme that keeps track of the “seasons” (summer, fall, winter and spring) so that time of night is tracked accurately all year long.

  • Patent number: 8529085
    Abstract: A light emitting diode (LED) lighting roadway lighting fixture and housing is provided. The lighting fixture comprises a center section enclosing a power supply for the LEDs. Two LED sections are positioned on either side of the center section and angled towards the center of the lighting fixture and the plane to be illuminated. LED engines are mounted on the LED sections to illuminate the plane.

  • Publication number: 20130057158
    Abstract: A method and apparatus for controlling a streetlight is provided. GPS data is required from a GPS coupled to a process of the streetlight. A geographic location of the streetlight is determined from the received GPS data. A real local time is determined from the GPS data and a sunrise and sunset time associated with the geographic location can then be determined. The on and off state of one or more LED lighting modules of the streetlight can then be controlled upon the determined sunrise and sunset times.
