Soraa and Kaai, an All Star LED Company

Soraa is a stealth cleantech startup that is focusing on LED technology and Kaai , workng for Blue Lasers. Khosla Ventures has invested in both of the aforementioned firms, and while company representatives aren't disclosing much at the moment, we do know that the duo is exploring ways to "exploit gallium nitride", which is also the basis for existing blue LEDs and blue lasers.Soraa is also known as SJS Technology, and is reportedly in the midst of a $5M fund raise.


What makes the companies intriguing are the founders Shuji Nakamura, Stephen DenBaars and some of the ex-staff from Lumileds and Cree. In Japan LED circle, Shuji Nakamura is a major celebrity. Nakamura invented the blue LED in the early '1993 while working for Nichia.
Nakamura also made history by suing his employer, which gave him a bonus of around $200 for his invention, and winning in court. The somewhat un-Japanese action on Nakamura's part resulted in a settlement in the millions. He later became a professor at the University of California at Santa Barbara. He also won the Millennium Technology Prize. (Refer to the interesting biography of Nakamura by Bob Johnstone called Brilliant I introduced beginning of the Month).

Stephen DenBaars, a professor of material science at the University of California at Santa Barbara, is one of the leading researchers on LEDs. DenBaars has said that if 25 percent of the lightbulbs in the U.S. were converted to LEDs putting out 150 lumens per watt (higher than the commercial standard now), the U.S. as a whole could save $115 billion in utility costs, cumulatively, by 2025. "They (Nakamura and DenBaars) found the next breakthrough in LEDs in 2000 and they have been working on it for seven years," said Tamer. Tamer, who formerly worked at Broadcom, will primarily focus on energy-efficiency investments. Earlier this month, for instance, the firm announced it has an investment in EcoMotors, which is developing diesel engines that could get 100 miles per gallon.

Let's watch out for the possibly brightest LED ever made by Soraa!

Illumitex will go for 300 Lm/watt LED in 2015

Illumitex LLC (Austin, Texas), started in 2005, the company now has 25 employees, with the toolset required to create and test HB-LED prototypes. Mass production will be done in Asia.

Paul Winberg VP of Engineering said a new startup aimed at the high-brightness light-emitting diode (HB-LED) market, says it has proprietary optics technology that will increase the amount of light emitted from the package.

Co-founder and CTO Dung Duong brought optics engineering ideas to the table, when three co-founders started the company in Winberg's garage. "Our packaging technology is such that we approach it from an optics standpoint, with the use of secondary optics," Winberg said. "By doing that, we can direct the light so it all comes down to the front of the package, which gives customers a much smaller package.

Illumitex buys commercial epitaxial sapphire wafers, and builds the diode much as other HB-LED vendors do. The company's advantage lies in the metal reflective layers incorporated into the flip-chip package, the external quantum efficacy is the more important metric. The highly refractive surfaces in an LED and its package can quickly dissipate the emitted brightness and turn light into heat, reducing the thermal benefits that LEDs offer.

The package measures 1.1 mm on a side, and 1.5 mm high, which Winberg said is "much smaller than anything else out there. That advantage stems from the secondary optics in the package, which get more light out." Flip Chip technology is mainly the process of Lumileds and that has certain good points as Gold to gold has very good heat dissipation highway, but the negative side is the high manufacturing cost as the Flip Chip process is slow typical in term of 1-1.2sec a LED, plus the need to have underfill by jetting machine.

There are only a few companies in the world produce Thermosonic Bonding equipment for LED. Namely, ASM, Panasonic and TDK.

Illumitex’s primary product will start at 100 then 150 Lm/W at 300ma driving current...till 2015, they would produce a LED with 300 Lm/W!
