Luminus Devices Receives Five Additional U.S. Patents for PhlatLight™ Technology

Issuance of Core Patents Reflects Luminus' Continued Investment in Intellectual Property Portfolio

WOBURN, MA -- (MARKET WIRE) -- April 30, 2007 -- Luminus Devices, Inc. today announced that it 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, bringing the company's total patents received to 11. Luminus is committed to protecting its PhlatLight technology with IP and has filed over 100 additional U.S. and international patent applications, many more of which are expected to issue in the near future.

Luminus Devices has leveraged its expertise in high-power LED technology to develop the proprietary PhlatLight product family, currently used in a variety of applications including projection TVs, LCD TVs, and other advanced high-definition displays and lighting systems. The underlying photonic lattices used in PhlatLight technology direct the photons through the surface of the LED, emitting substantially more light and in a narrower, collimated beam that is more readily collected and delivered to its target. This, combined with Luminus' advanced packaging technology, enables more powerful solid-state light sources than have ever been realized to date, setting PhlatLight apart as an entirely new category for LEDs. Luminus has also developed a cost-effective method of manufacturing PhlatLight LEDs in high volume, at the company's state-of-the-art manufacturing facility.

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.

"There has been a rapid increase in the market's adoption of our PhlatLight technology, which is enabling new classes of advanced high-definition displays and solid state lighting," said Alexei Erchak, co-founder and chief technology officer for Luminus Devices, Inc. "We continue to improve and expand the use of PhlatLight, uncovering new opportunities where PhlatLight technology is well suited to address a specific design challenge. For example, we've found many high-brightness applications benefit greatly from replacing hundreds or even thousands of LEDs with a single PhlatLight LED."

Luminus has significantly ramped up shipments of PhlatLight chipsets, which are currently used in projection TVs offered by Samsung and NuVision. Luminus' latest chipset, the PhlatLight PT120, is being mass produced for projection TVs with screen sizes as large as 61 inches, while its PT39 chipset is being used in LG Electronics' HS101 pocket projector, the brightest LED front projector in production. The company continues to lead the industry in developing breakthrough LED light sources for advanced display and other high-brightness applications.
