ALT, Inc. Introduces High-Efficiency Monolithic LED Driver Technology

Advanced Lighting Technologies, Inc. (ALT) today announced a high-efficiency and highly reliable LED lamp driver solution (LED driver) comprising no bulky, unreliable components such as capacitors, coils or EMI filters. ALT''s ultra reliable “AC LED Light Engine”consists of an LED array and ALT’s novel driver, requiring no other parts except two AC power wires. ALT’s driver is compatible with all dimmers, is over 90% efficient, has a power factor greater than 0.95, and the entire driver can be integrated into a tiny 16 pin or 8 pin chip.

ALT's high-efficiency and highly reliable LED lamp driver solution (LED driver) comprising no bulky, unreliable components such as capacitors, coils or EMI filters. Unlike the few other companies announcing similar products, ALT’s target is to offer an ultra reliable “AC LED Light Engine” comprising only an LED array and a tiny 8 pin or 16 pin chip, requiring no other parts except two wires to connect to the AC outlet. The ALT LED driver is fully compatible with all dimmers, is over 90% efficient and has a power factor greater than 0.95.

Working printed-circuit board prototypes to be unveiled at next week’s LightFair Conference in Las Vegas demonstrate proof of concept and the technology. Because there are no reactive parts in the ALT driver circuit, the entire LED driver can be reduced to a single ASIC chip or be embedded as an IP block in a customer-specific system-on-a-chip. ALT will be conducting meetings with potential partners by appointment at LightFair2012 as well as offering daily 8:00 AM morning technology briefings May 8 - 11 at the company’s demo suite.

Wayne Steinhoff, ALT’s CEO, states, “Combining the ALT single chip driver with an LED array creates the ‘Ultimate Lighting Device’, an electric light completely made of solid state components that can be manufactured in large volumes completely by automated equipment. ALT has working prototypes to prove the concept, and ALT is looking to partner with semiconductor companies and lighting companies to bring this revolutionary technology to market.” The ALT driver is designed for an extremely wide range of output power (1W-300W) and ambient temperature (-50ºC to 150ºC). The technology is protected by a broad “frontier” pending patent executed by an experienced inventor, Beniamin Acatrinei, who originally conceived of the novel constant voltage constant current (CVCC) driver topology during the 1995 – 1997 time period when he obtained his first US patent.

ALT principals Wayne Steinhoff, ALT CEO and former President & CEO of Fawoo LED Technology NA and past Vice President & General Manager of Osram Sylvania; Charles Jerabek, ALT Board member and former President & CEO of Osram Sylvania and past Chairman of NEMA (National Electrical Manufacturers Association); Ray Martin, ALT Director and Ben Acatrinei, ALT Director and Inventor, will be conducting meetings with potential partners by appointment at LightFair2012 in Las Vegas, May 8 – 11.

ALT will be demonstrating working prototypes in a typical PAR-38 fixture configuration, and potential partners, media and analysts interested in a technology briefing in advance of LightFair, or at LightFair, may request an appointment by emailing rich(at)prmgt(dot)com or calling (941) 780-8100. ALT will also be conducting a daily 8:00 AM to 9:00 AM morning technology briefing May 8 through 11 in Suite 1719 at the Hilton Grand Vacations Suites located next to the Las Vegas Convention Center at 455 Karen Avenue.
