Researchers at the Niels Bohr Institute have discovered a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. Using lasers, researchers cooled membrane fluctuations to minus 269 … [Read more...]
Thermal Modeling and Testing for LEDs and Luminaires
Mentor Graphics Corp. has introduced the T3Ster (“trister”) thermal transient tester for LEDs, board-level LED arrays and luminaires. Together with the company’s FloTHERM thermal simulation tool based on computational flow dynamics (CFD), lighting designers can model and improve heat transfer through the LED, printed circuit board (PCB) or luminaire system during design and … [Read more...]
LED Driver IC Market Buoyed by Growth in Backlights
A new report from Strategies Unlimited finds that the market for LED driver ICs is sizeable at $2 billion in 2010, buoyed by strong growth in LED backlights in mobile phones, TVs, and monitors. Innovations promise to help meet aggressive price and performance targets necessary to expand further the market for LED lighting, particularly in replacement bulbs. These innovations … [Read more...]
GE Invests in LED Cooling Technology Creator
GE has provided capital and entered into a license agreement to access Nuventix’s patent portfolio. Nuventix developed a method for moving air to cool LEDs using a single oscillating membrane, called a SynJet®, as an alternative to traditional fans. Lighting fixture companies can employ Nuventix’s technology for spot, down, track and accent lighting fixtures that also use … [Read more...]
