Patent number: 8152325Abstract: A reflective surface electric road flare designed to be positioned on a roadway and to emit light to alert oncoming drivers to a hazard on the roadway. The flare comprises a housing supporting a circuit. The circuit comprises an led light source, a power controller and a power supply. The power controller energizes the led light source with the power supply such that the led light source emits light according to its design specification. The emitted light is concentrated about the horizontal by a lens into a horizontal light beam visible throughout the azimuth. Concentrating the emitted light into a horizontal light beam increases its intensity as perceived by oncoming drivers located within the projected horizontal light beam. A portion of the horizontal light beam intersects a top surface of the road flare where it is reflected towards oncoming vehicles.Type: GrantFiled: September 10, 2009Date of Patent: April 10, 2012Inventor: Kevin F McDermott
