Barely one month after reporting a $10 million venture investment, QD Vision Inc. says it has taken in $3 million from DTE Energy Ventures to help expand the market for its technology for LED lighting and displays products.
In addition to the $10 million round announced in December, QD Vision has raised a total of $33 million in venture capital financing from investors including North Bridge Venture Partners, Highland Capital Partners and In-Q-Tel, the investment arm of the CIA.
Watertown-based QD Vision rolled out its first product last year, a nanotechnology-based optic for a new high-efficiency, high-color-quality LED lamp developed by Nexxus Lighting Inc., based on QD Vision’s Quantum Light technology.
Founded in 2004 by a research team from MIT, QD Vision’s Quantum Light technology uses quantum dots to produce high output LEDs that draw less power than traditional products, according to the company.
QD Vision reported last June landing a Phase 2 Small Business Innovation Research grant worth $775,000 from the U.S. Army for the development of its technology for use in micro displays.
