LED technology has been gaining a lot of steam over the past few years. In accordance, we have seen the prices of LED light fixtures and LED light bulbs decrease. Thrilling new projects involving OLEDs have tickled our fancies, and colossal displays of LED lighting – turning bridges into dragons, creating towers of kaleidoscopic light – have entertained us. But the most exciting developments in LED lighting fall within the realm of smart lighting.
There’s a new LED light bulb in town. And it has been designed to help you fall asleep. Here’s the premise: Before we had electric lights, we adapted our sleep patterns to the rising and setting of the sun. But these days, many of us have completely lost touch with the natural rhythms of light and darkness. We stay up until the wee hours, our faces washed in the light of a computer or tablet screen, our eyes glazed over. We wake up to alarms, feeling perpetually like we haven’t gotten enough sleep. Sound familiar?
A couple months back, Medical News Today published an article on the effect of room lighting on decision making. Invoking crime dramas in which suspects are interrogated under bright lights, the report suggests that people tend to feel emotions more intensely in brighter light. This finding is significant not just for retailers but for anyone who consciously uses light in their spaces for a desired effect.
Recently, Digital Trends profiled a new product being developed by an associate professor of optics and experimental physics who works at the University of Insubria in Como, Italy. The professor’s name is Paolo di Trapani, and his work has a lot of people excited. For all the rapid progress that has been made with LEDs, no one else has made this important step towards recreating natural light.
A recent TedTalk about LED lights has garnered about a million and a half views. That high number isn’t surprising, given that LEDs have been making headlines a lot, lately. Tons of informational articles about the efficiency of LED light bulbs and how to choose them have been circulating online. But this TedTalk is about something quite different – data transmission.
The talk was given by Harold Haas, Chair of Mobile Communications at the University of Edinburgh, who coined the term LiFi, or light fidelity, to refer to a visible light communications (VLC) system. LiFi uses LEDs, which, of course, are electronic semi-conductors, as a medium to deliver networked, mobile, high-speed communication.
Below are five of the coolest lighting news items that caught our attention in January 2014, from Detroit’s big LED plans to a light-up bridge that looks like a dragon. Feeling slightly peckish? Here’s a light buffet…
1) Public Lighting Authority to install LED lamps in Detroit, cut installation period in half
Detroit is redoing the public lights in all city neighborhoods. At a meeting on Wednesday, January 29, Mayor Duggan and the state-create Public Lighting Authority decided not only to use LED lamps exclusively, but also to speed up the process of relighting the city. Read more…
