Human Centric Lighting Hits a Home Run with the Seattle Mariners

The Seattle Mariners may have just upped their game when they retrofitted their clubhouse with an LED lighting strategy focused on intensifying the moods, energy levels and performance of their players.

The LED-based project, headed up by Planled CEO John Hwang, Lighting Wizards principal Stan Walerczyk, and Harvard professor Dr. Steven Lockley, aims to prepare the players for the game with one type of light, and then wind them down afterwards with another. The desired outcome is a baseball team that’s alert and awake before and during the game, and rested and relaxed after.

What is Human Centric Lighting?
Human centric lighting (HCL) is the study and application of light on the human body: mainly mood, energy & health. There’s no question that recent advances in LED lighting technology have helped our planet with its cost-savings and energy efficiency, but how might it benefit me, as a human being? Can a personal lighting strategy make me a better wife, mother, employee? Can it make a professional athlete perform better? (more…)

Light News: The 2015 International Year of Light

IYOL 2015 Logo2015 is the International Year of Light, and while we openly admit to being obsessed with anything light-related, we also understand that the rest of the world may not share our level of amazement. (Okay, we really don’t understand it, but we’ve come to accept it.) So imagine our joy when the United Nations announced this global initiative to educate the world about “the importance of light and optical technologies in their lives, for their futures and for the development of society.”

They could have done an International Day of Light, or even a month dedicated to light, but a year, folks. One. Entire. Year. (more…)

Using Your Tablet or Smartphone in Bed May Be a Lousy Idea

using your tablet in bed bad idea

The conclusion of Daylight Saving time this past weekend means the night comes a little earlier. Logic may tell you that the longer and darker evenings will make falling asleep easier. However, even though the nights are longer we are also using smartphones, tablets and HDTV’s more and more in the 21st Century, particularly at night. Some scientists believe that Mr. Sandman has a new nemesis – the little blue light in all of these new-fangled devices.

What It Is

Naturally occurring blue light, a short wavelength in the light spectrum, is abundant in sunshine and hugely beneficial during the day when the majority of people need to be awake and alert. It’s been said to boost mood and increase attention span by stimulating sensors in the eye that then send signals to our internal clock. It also suppresses melatonin — a hormone produced by humans that helps regulate sleep-wake cycles — more than any other light wave. In fact, blue light is so efficient at suppressing melatonin that it’s often used to treat seasonal sleep disorders by mimicking the naturally occurring light of the sun. Here is where the problem surfaces — modern devices like high definition televisions, smartphones and tablets are massive producers of blue light. This blue light wreaks havoc on our circadian rhythms — our internal “body clock” that regulates 24-hour cycles, approximately — by basically tricking our brains into thinking it’s still daytime.

Blue LED Light

The 2014 Nobel Prize in Physics Goes To …

Nobel Prize in Blue LED

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 giving 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. (more…)

What Is Smart Lighting?

Smart LED 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.

New LED Light Bulb Mimics Sunset to Improve Sleep

Sunset

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?
