The chip-array packaging, codenamed Cetus family, runs on DC or AC, making the company one of only a handful to offer AC LED solutions. The Cetus features a unique cavity design with each cavity connected through led high bay light ceramic substrates, allowing Intematix to build any array configuration to deliver color rendering that is pleasant to the eye, virtually mimicking natural light, according to the company’s vice president for engineering, Harik Su, also the inventor of the unique packaging design. He says such arrays truly contain all the desirable features lighting makers look for, including easy design, binning, efficient thermal management, and simplified and scalable power and spatial design.

The Apus line of single chip packaging, using square substrates of only 3mm to 5mm, delivers up to 80lm at one-watt for 5500K cool white and 70lm at one-watt for 3300K warm white. When combined with the company’s latest red phosphor, Apus boasts color rendering typically greater than 90. Cetus is available in configurations of four to hundreds of chips in series or parallel, as well as series-and-parallel combinations. Li predicts that AC LED to mature as lighting technology when its luminous efficacy rises to 100 lumen per watt, a rate he believes will be realized sometime in 2009.

Still relying on American ingenuity, the mainland Chinese factory has all its latest tech supplied by Intematix’s American headquarters. Intematix, since its opening in 2000, boasts an apparently unbeatable team of crack scientists, with a 25-member R&D force, all PhDs including Li himself, who have helped to lay down a solid technological foundation. "We have experts in electronics, photonics, materials, physics and chemistry," says Li, who has a superconductivity-science degree from Stevens Institute of Technology, an elite university in the U.S. Having started up making dielectrics materials for chip-making, optoelectronics and magnetic materials, Li in 2004 diversified into phosphor led high bay light backed by official American funding.The company recently brought onboard Jeff Lagaly as its vice president of LED lighting sales to expand its global market share in the segment. Formerly the Global Sales Director for yaham Lighting, Lagaly succeeded to not only introduce but also make the XLamp LED line a $100 million-plus sales generator.
