Cooper Lighting has upgraded its outdoor LED LightBAR™ technology. The new system’s optical performance delivers improved lumen output and efficiency, while continuing to offer up to 75% in energy savings over traditional High Intensity Discharge (H.I.D.) outdoor lighting sources. Cooper Lighting’s LightBAR™ technology features the company’s AccuLED Optics™. The system’s … [Read more...]
Electrical Insulation Systems Standard
IEC/TS 62332-1:2011(E) is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a dual-temperature test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). The following significant technical changes with respect to the … [Read more...]
New Superconductor Fibers Carry 40 Times More Electricity
Researchers at Tel Aviv University have developed superconducting wires using fibers made of single crystals of sapphire to be used in high powered cables. Factoring in temperature requirements, each tiny wire can carry approximately 40 times more electricity than a copper wire of the same size. They have the potential to revolutionize energy transfer. High power … [Read more...]
Bristly Particles Could Manage Heat Flow in Electronics
A well-known method of making heat sinks for electronic devices is a process called sintering, in which powdered metal is formed into a desired shape and then heated in a vacuum to bind the particles together. In a recent experiment, students at MIT led by Kripa Varanasi, d’Arbeloff Assistant Professor of Mechanical Engineering, tried sintering copper particles in air 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...]
