Luminus Devices has received five new U.S. patents for its PhlatLight™ (Photonic Lattice Light Source) technology. The new patents add to the six patents previously granted to Luminus (see news item). The company says it has filed over 100 additional U.S. and international patent applications.
Luminus has invested over $10 million dollars in IP development and the company’s extensive portfolio now provides coverage for high-power LED chips, packaging and optical systems. While Luminus is currently manufacturing PhlatLight LEDs for large screen high-definition displays, PhlatLight technology can be applied to many other LED applications, some of which Luminus is exploring through various collaborations and licensing agreements.
Nexxus receives patent for LED pool & spa lighting
Nexxus Lighting has been issued a patent for its Galaxy/IGP LED pool light. US patent number 7,204,602 is directed at an LED light assembly that utilizes multiple red, green and blue LEDs to change the color of the water and a control circuit that allows users to change colors or programmed light patterns with the on/off toggling of a switch.
"We applied for this patent back in 2002 and we believe it is a fundamental technology to many of the pool lights that have been introduced since we introduced our IGP," stated inventor Roy Archer, Nexxus Lighting's General Manager and Director of Orlando Operations. "LED lighting for pools has become very common for both new construction and also for the replacement of old incandescent/halogen light bulbs to provide dramatic color changing and lighting effects with the flip of a switch. Our technology is the foundation on which many of the products were built."
Nexxus Lighting, formerly Super Vision, now has 21 issued patents, four of which relate to LED technology. The company recently signed a patent license agreement with Color Kinetics after a long and bitter dispute.
Recent US patents related to LEDs
Number: 7210806
