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...]
Wire Grid Cools Light Emitting Diodes
Ventiva has come up with a wire grid that effectively cools light emitting diodes, solid state lights and other electronic components in a way that can be considered both active and passive. A small charge is applied to some of the wires in Ventiva's mesh, which creates ions in the localized atmosphere. The ions begin to move and push against molecules in the air, which in turn … [Read more...]
Invention Speeds Solar Cell Quality Tests
Three scientists from the U.S. Department of Energy's National Renewable Energy Laboratory have developed a way to assess the quality of solar cells at a speed that is orders of magnitude faster than had been done before. The instrument, Real-time QE, licensed and embellished by Tau Science Corp. as FlashQE™, uses light-emitting diodes, high-speed electronics and mathematical … [Read more...]
New High-Brightness LED Driver Simplifies Area-Lighting Design
National Semiconductor Corp.’s new LM346 is a highly integrated linear LED driver that simplifies the design of high power, wide area lighting fixtures such as streetlights. The LM3466 provides a complete system that drives each LED string from any off-the-shelf AC/DC constant-current power supply. Learn more from National Semiconductor. … [Read more...]
