Silk LED bulb emulates natural sunlight

By - June 25, 2015 1 Picture

Our well-being and mood throughout the day is largely influenced by the light we are exposed to. Following this principle, a start-up called Saffron has developed the prototype of a LED light that can sync our internal clock to the natural shifting color spectrum of the sun. The light is called Silk by Saffron, and the designers claim it can improve our humor and sleep patterns by giving us get the right kind of light for the each time of the day.

By - June 9, 2015 6 Pictures

Some notable advances have taken place in the world of LED lighting of late. From Ikea's flexible lighting tiles to Phillips' $5 bulbs, those looking to switch off their incandescent globes for good have plenty of practical and quirky options to choose from. But, just as it did with vacuum cleaners, hand dryers and air purifiers, Dyson has arrived and is promising a superior solution. Inventor Jake Dyson says the company has built the first light that cools LEDs properly, enabling them to last 37 years.

New invention expands Wi-Fi bandwidth tenfold

By - April 21, 2015 3 Pictures
The vast range of Wi-Fi-enabled devices available today means that anyone could have several personal electronic devices all trying to connect to a network simultaneously. Multiply this by many hundreds of people in a busy public place with Wi-Fi connectivity and this often means that available bandwidth is greatly reduced. To help address this problem, researchers at Oregon State University claim to have invented a new system called WiFO that incorporates infrared LEDs to boost the available Wi-Fi bandwidth by as much as ten times.

Optical antenna may allow LEDs to replace lasers in host of devices

By - February 4, 2015 3 Pictures
By applying 120 year old radio frequency antenna theory to the much newer field of photonics, researchers at Lawrence Berkeley National Laboratory claim to have produced a prototype optical antenna that increases the intensity of emission from a nanorod light source by more than 115 times. This technique may offer the opportunity to replace power-hungry lasers in short-range optical communications devices with enhanced low-power LEDs. Read More
