20120320586 | REFLECTOR WITH FOCUSED OUTPUT - A reflector with focused output is disclosed. The reflector comprises a reference parabolic portion and a plurality of non-reference parabolic portions. A focal length of the plurality of non-reference parabolic portions is determined from a focal length of the reference parabolic portion. In one embodiment, the focal length of the plurality of non-reference parabolic portions is a perpendicularly projected distance from a focus of the reference parabolic portion onto a central axis of the plurality of non-reference parabolic portions. In one embodiment, the focal lengths of the reference parabolic portion and the plurality of non-reference parabolic portions are scaled by a constant. A method of designing a reflector and an obstruction light that uses the reflector is also disclosed. | 12-20-2012 |
20110002118 | LED OBSTRUCTION LIGHT - A light emitting diode (LED) light with a corrugated reflective surface is disclosed. The corrugated reflective surface reflects and diffuses light beams emitting from a light source having at least one LED. The corrugated reflective surface can be concavely curved. The curvature and the corrugations of the reflective surface can be designed by an equation to achieve a specified beam spread. | 01-06-2011 |
20110001626 | APPARATUS AND SYSTEM FOR LED STREET LAMP MONITORING AND CONTROL - An LED street lamp including a PLC modem and a control circuit is disclosed. The LED street lamp is able to receive control commands from remote controller. It is also capable of doing self-control based on status information gathered by diagnostic circuit. A system for LED street lamp monitoring and control is also disclosed which includes a central controller, a distribution network and a plurality of LED street lamps. Based on the PLC technology, each LED street lamp can be centrally controlled by the central controller. | 01-06-2011 |
