For centuries man lit his night with an oil lamp that created only about 1/10th of a lumen per watt (a very small amount of light produced for the expenditure of a standard unit of energy). Then in the late 19th century the incandescent light bulb was invented and that eventually provided about 16 lumens per watt. In the late 1930s the fluorescent lamp became a reality and gave us an amazing average efficacy of about 70 lumens per watt. Now in the early 21st century still another revolutionary development is taking place – light emitting diodes (LEDs) are or will soon give us 300 lumens per watt. Think about the amount of change in the way we have lit our homes, offices, stores, factories, and streets in just the last 20-30 years. It is nothing short of astonishing and you can bet that more change is on the way in how we light the way we live. Continue reading »

Smart LIghting Control What Is Smart Lighting?

via blog.nxp.com

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.

sunset New LED Light Bulb Mimics Sunset to Improve Sleep

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?

bigstock Big Sun Element of design 18659510 Lighting Levels Affect Consumer Decision Making

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

 Pegasus Lighting Roundup: January 2014

Light Bulb Question Mark Green Where Did the Phrase Go Green Come From?

“Going green” has come to symbolize environmentalism in such a familiar way that most of us don’t think twice about who first coined the phrase.

I was curious about the origin of the term and wondered what made it take such strong hold in the English language. Speaking of curiosities, remember Heinz’s food flop several years ago when they decided to go green (literally) with ketchup? Glad that didn’t take hold.

Most people associate the beginning of the green movement and environmentalism with the publication of Silent Spring by Rachel Carson in the 1970’s.

Surprisingly, it dates back even further, to Henry David Thoreau’s writings in the 19th century. Thoreau spoke about living a “green” life in The Maine Woods in his call for conservation, forest preservation and respect for nature. You are probably familiar with several of Thoreau’s famous inspirational quotes (i.e., “Go confidently in the direction of your dreams,” or “What lies behind us and what lies ahead of us are tiny matters compared to what lies within us”). His greener remarks include:

What is the use of a house if you don’t have a decent planet to put it on?

This one’s my favorite (Thoreau, you were a funny guy!):

Beware of all enterprises that require a new set of clothes.

Did you have any idea the U.S. “green movement” was rooted in early American philosophy?

eco friendly light bulb lying The Biggest Impact of the EISA Is Here: Bye Bye 60 Watt Incandescent

It has taken 7 years but we are now here. On January 1, 2014 both the 60-watt and 40-watt incandescent light bulb will no longer be produced as a result of the Energy Independence and Security Act of 2007 (EISA) signed by President George W. Bush. In years past we have lost the 100-watt and 75-watt. However, this next phase will probably have the biggest impact. Why? Simple. The 60 and 40-watt light bulbs are the most popular. According to Residential Lighting, they represent over 50% of all light bulbs used today.

We have been covering the incandescent phase out on this blog for the last couple of years. However, as a reminder, a primary goal of this law is to raise appliance and lighting efficiency standards.

The 60 and 40-watt light bulbs will not just vanish into thin air on January 1, 2014. You will probably still see them in stores for a couple of months. The key is that as of 1/1/14 they can no longer be imported into or manufactured in the United States. Continue reading »

Is there a better way to kick off a lighting design awards show than to distribute glowsticks to the finalists for “experimentation”?

Well, we can’t think of one.

The photos below have been floating around on Twitter in anticipation of the 2014 Lighting Design Awards, a worldwide architectural lighting competition to be held in London on March 20. Leave it to the creative lighting professionals to craft a rainbow motif, an “alien landing” scene, and a dog collar – all from a box of glowsticks.

This slideshow requires JavaScript.

Photos: Innovation – @havellssylvania. Glowstick Art #1 – @zanocontrols. Alien Landing – @zanocontrols. Finalist Glowsticks – @iGuzziniUK. Glowstick Art #3 – @zanocontrols. #LDA 2014- @lightingmag. Dogs with Glowsticks – @lucentlighting

Which would you vote for?

Follow @LDA_2014 and @iGuzziniUK on Twitter for more, and check out a shortlist of the finalist projects and products for the 2014 Lighting Design Awards here.
