A patent by the inventors Negley, Gerry van de Ven, Antony Paul; Pickard, Paul filed on December 8, 2010, was published online on November 19, 2013, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents. The following quote was obtained by the news editors from the background information supplied by the inventors: "Light emitting diode (LED) lighting systems are becoming more prevalent as replacements for existing lighting systems. LEDs are an example of solid state lighting and have advantages over traditional lighting solutions such as incandescent and fluorescent lighting because they use less energy, are more durable, operate longer, can be combined in red-blue-green arrays that can be controlled to deliver virtually any color light, and contain no lead or mercury.
