1.4-Meter Organic LED TV Sets to Be Unveiled at Consumer Tech Extravaganza

For years manufacturers have tantalized consumers with the promise of organic light-emitting diode (OLED) televisions capable of delivering more brilliant colors (including deeper blacks), and greater levels of contrast and brightness than any other television screen—all with rapid video response rate. OLEDs are already in regular use to provide crystal-clear screens for smart phones, car [...]

The quest for cool: Novel approach leads to brighter, more efficient white LEDs

Intematix, ChromaLit

For phosphor-based light-emitting diodes (LEDs) to continue their current trend of displacing incandescent and fluorescent bulbs, makers of these small semiconductor-based lights are looking to, among other things, continue improvements in energy efficiency, increase longevity and reduce glare. LEDs are illuminated by the movement of electrons in a semiconductor material, but the common practice of [...]

A World Record for Energy-Efficient Lighting

Philips-TLED-prototype_researcher-Coen-Liedenbaum-1.jpg.492x0_q85_crop-smart

On Thursday, Philips announced that it has developed the world’s most efficient “warm white” LED lamp. Designed to replace the fluorescent tube lighting that is ubiquitous in offices and industrial facilities, the new TLED (tube-style light emitting diode) has the potential to reduce worldwide energy consumption by more than 7%. Innovation in the LED lighting [...]

More on food sourcing and food sustainability

I heard this story on NPR/PRI’s The World while driving home from yoga last night. Here’s the tl;dr of it: a Dutch company is perfecting ways to grow food indoors using LED lights and elaborate climate controls. By optimizing light levels and wavelengths, a range of crops can be grown. One could theoretically grow plants [...]
