| 20120001566 | POWER SUPPLY FOR LIGHT EMITTING DIODE ROADWAY LIGHTING FIXTURE - 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. | 01-05-2012 |
| 20110194281 | LIGHT EMITTING DIODE ROADWAY LIGHTING OPTICS - An optical module for an lighting fixture for providing roadway illumination. The optical module comprising circuit board having a plurality of light emitting diodes (LEDs). A reflector cups surrounds each of the plurality of LEDs, the cup comprises a narrow end surrounding the LED and a larger opening at a second end opposite the LED. A refractor lens cover comprising a plurality of molded lens, each lens positioned at the second end of the reflector cups. | 08-11-2011 |
| 20110188233 | LIGHT EMITTING DIODE (LED) ROADWAY LIGHTING FIXTURE - 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. | 08-04-2011 |
