2014 Nobel Prize in Physics awarded to inventors of blue LEDs

Thomas Edison may have invented the lightbulb, but he never received the Nobel Prize for it. Isamu Akasaki and Hiroshi Amano at the University of Nagoya, and Shuji Nakamura working at Nichia Chemicals in Tokushima, Japan have proven more successful, being awarded the 2014 Nobel Prize in Physics for their invention of the blue LED, which is the key to modern energy-efficient lighting.

Nature inspires color-sensitive, CMOS-compatible photodetector

Researchers at Rice University's Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras. Read More

Review: Knog's Qudos Action camera light for GoPro Hero

We've seen a plethora of accessories for the GoPro Hero actioncam cropping up over the past few years, including everything from stabilizers to drones to helmet-mounted poles. Surprisingly, though, except for scuba-specific models, there's been almost nothing in the way of lights. Australian bike gadget manufacturer Knog recently set out to fill that void, by releasing its Qudos Action light earlier this month. I recently had a chance to get my hands on the thing, and liked what it had to offer. Read More

10 Gbps Li-Fi system shows wireless data transfer in a new light

Light might be the preferred option for transmitting data over long distances via cables, but when it comes to short range wireless, radio waves rule in the form of Wi-Fi and Bluetooth. Now Mexican company Sisoft, working with researchers from the Autonomous Technological Institute of Mexico (ITAM), has developed a wireless technology that transmits data in visible light emitted from LED lamps, while lighting the room at the same time.
