Jacksonville jilts GE intelligent street lighting

The city withdraws after a pilot IoT deployment because it “had other priorities.” Meanwhile, GE’s San Diego trial advances to a commercial stage. Amid all the hubbub about how smart street lighting will underpin an Internet of Things (IoT) push by cities to operate more efficiently and intelligently, Jacksonville, FL has served a stark reminder […]

Nanorod LEDs with Two Functions Could Make Multifunctional Displays

Cellphones and other devices could soon be controlled with touchless gestures and charge themselves using ambient light, thanks to new LED arrays that can both emit and detect light. Made of tiny nanorods arrayed in a thin film, the LEDs could enable new interactive functions and multitasking devices. Researchers at the University of Illinois at […]

Health fears make city think twice on major LED decision

The city of Montreal will settle on a final decision next week on the increasingly controversial matter of replacing 132,000 street lights with LED. It had originally been intended that the current incandescent street fixtures would be replaced with 4,000 Kelvin LEDs. However, after a number of negative reports, including one from the American Medical […]

LECs – The Light of the Future Thanks Nanostructures

In future they are to light up the inside of handbags or make evening joggers stand out in the dark: Light-emitting electrochemical cells, LECs, offer many advantages compared to familiar LEDs, but there’s still something lacking – the right light. Until now only yellow light LECs are suitable for realistic use. But at least one […]

Engineered “Sand” May Help Cool Electronic Devices and LEDs

Giorgia Tech Research reports that Baratunde Cola, associated professor at the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology, would like to put sand into your computer and other electronic devices. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling […]

Lumileds and BluGlass Collaborate for Developing RPCVD LEDs

Australian technology innovator BluGlass Limited has today announced that it has entered into an exclusive collaboration agreement with Lumileds. Lumileds develops, manufactures and distributes LEDs and automotive lighting products. The two companies will work together to explore potential use of low temperature RPCVD for specific LED applications defined by the agreement. This agreement follows on […]

New phosphor blend for LEDs could crank up Li-Fi speed

Adding perovskite to the material that converts blue LED light into white boosts visible light communication modulation rates by a factor of 40, researchers find, improving the capabilities of Li-Fi. LED-based data speeds could operate 40 times faster than they do today if manufacturers alter the design of the phosphors that convert light from blue […]
