SAN FRANCISCO—Bridgelux Inc., a Livermore, Calif.-based developer of LED lighting technologies, said Thursday (May 10) that Japan's Toshiba Corp. made an equity investment in the firm of undisclosed size.
Bridgelux also claimed that the two companies have achieved the industry's top class 8" GaN- on-silicon LED chip, emitting 614mW, <3.1V@350mA with 1.1mm square chip, just months after they have engaged in a joint collaborative agreement earlier this year. The two companies plan to further accelerate their development efforts for LED chips, which have seen increasing demand for LCD panels and lightening systems worldwide, Bridgelux said.
Last September, the Silicon Valley/San Jose Business Journal reported that an unnamed Japanese conglomerate invested $20 million in Bridgelux. The publication reported that unnamed sources had identified the Japanese firm as Toshiba. The report also indicated that Bridgelux was on the verge of laying off 20 percent of its workforce and ceasing on-site chip production.
The Business Journal report came just one month after Bridgelux announced it raised $60 million in a series E round of funding from a group of venture capital firms.
"Toshiba and Bridgelux have already been engaged in the development of the technology, and the equity investment brings both companies one step closer to a more strategic relationship and achieving our shared goal of driving down the cost of Solid State solutions for the general lighting market," said Bill Watkins, Bridgelux CEO, in a statement issued Thursday.
