How LED lighting design can affect Circadian rhythm

Posted by Rob Gemmell on Aug 4, 2014 6:52:00 AM

 

Like so many other things - TV listings, flights, trains and appointments - your body operates on a clock. Experiencing that sluggish feeling after jet lag and Daylight Savings Time happens for a reason, and it all has to do with our circadian rhythm.

Human-centered lighting expected to be top trend

Posted by Rob Gemmell on Jul 31, 2014 5:44:00 AM

 

Commercial LED lighting design that focuses on the needs of occupants as well as cost savings is expected to be a major trend between now and 2020.

While further optimizing lumen output, light uniformity and luminous efficacy, lighting manufacturers and designers are expected to direct more emphasis and research toward the soft costs of lighting - glare reduction, circadian regulation and employee morale - Green Biz reported. The expanding proliferation of studies regarding the role of lighting in concentration and productivity in educational, healthcare, corproate and other commercial facilities has caused a turning point in discussion around fixture specification.

Improve physical and psychological health with tunable lighting

Posted by Rob Gemmell on Jul 28, 2014 7:55:00 AM

 

Artificial light has created more "time," so to speak, for all of humankind to get things done. We can work whenever we please, carry on business 24 hours a day if needed. However, as animals who have spent millennia living by the rhythms of the sun's rays, this artificial option has definitely taken a toll on some individual's health and personal well-being. 

Because 8-hour day and night shifts are not going to stop anytime soon, the solution must come from the lighting source itself: In comes tunable lighting.

The sun doesn't provide the same level or even color of light throughout the day, so sitting under the same white light in an office, hotel or school can make you tired when you need to stay awake, or, conversely, too wound up when your body should be starting to relax. Tunable lighting mimics that natural ebb and flow of sunlight, working more symbiotically with your own circadian rhythms.

Form as well as function in LED lighting

Posted by Rob Gemmell on Jul 24, 2014 11:37:00 AM

 

During the early days of LED manufacturing (which weren't too long ago), finding a balance between the new technology and designing beautiful fixtures wasn't always the easiest task. Everything from the color of the light, ergonomics and product design was typically an afterthought for many in the beginning, but all of that has definitely changed as LED have been maturing within the lighting industry.

"We were all kind of drunk on efficiency," Chris Bailey, a solid-state lighting technology strategist, explained to Architectural Lighting.

In a mad sweep to get products on the shelves and LEDs into the hands of lighting designers and architects worldwide, form oftentimes sat on the backburner as function took the lead role. And it's understandable. During the initial phase, the economy was struggling and environmental friendliness was the biggest challenge facing not just the lighting industry, but the energy sector as a whole. So, it makes sense that energy-efficiency was the main goal during the first days of LED manufacturing.

Cutting down the lighting lumens to shave off the pounds

Posted by Rob Gemmell on Jul 22, 2014 12:16:00 PM

 

Dimming the lights during a romantic meal does more than set the mood.

Lower lumen outputs may also help you lose weight. In addition to sweating off a few pounds at the gym or lowering your intake of sweets, turning the lights down low may help you reduce your calorie intake. According to a 2012 study originally published in Psychological Reports, dimmable commercial lighting design in conjunction with milder music can be used to get people to avoid wolfing down their meals, Reuters reported.

Color Quality with LED Lighting Systems

Posted by Rob Gemmell on Jul 18, 2014 6:37:00 AM

 

LEDs might require lighting designers' clients to dig a little further into their pocketbooks, but there are numerous reasons why lighting designers and architects should stick to their high reverence for LED lighting - and color quality is definitely one of them.

One of the best reasons to make the switch to an LED lighting system is the major benefit you can achieve regarding color quality and illumination. In the lighting industry, getting the appropriate amount of color flexibility in your fixtures can be a challenge, especially if you are a lighting designer or architect that is being paid to light up a space that relies on some strict parameters, such as those applicable to art, retail and hospitality venues.

Easy ways to determine efficient LED lighting controls for your space

Posted by Rob Gemmell on Jul 16, 2014 8:31:00 AM

 

By now, most lighting designers and architects know that LED linear lighting systems are the way to go in terms of efficiency and practicality for modern buildings. However, one roadblock for these professionals is choosing what kinds of lighting controls they want for their given space.

Lighting up the library with LED systems

Posted by Rob Gemmell on Jul 14, 2014 5:04:00 AM

 

If you're not much of a bookworm, you might not have set foot in a library for a while. Although there's often plenty of space to peruse pages, libraries are also hubs of research, areas to complete homework, apply for jobs in the computer labs, work on groups projects in study rooms and sometimes host events. As a result, library lighting has to be as multifaceted as the tasks that happen around the stacks. Additionally, it has to highlight all of the knick knacks and posters on the wall while operating at a brightness that won't be damaging to any older texts.

The answer to these demands is fixtures equipped with dimmer switches, according to Libris Design.

Chronobiology: Connections between health, lighting and architecture

Posted by Rob Gemmell on Jul 11, 2014 5:14:00 PM

 

LED lighting designers have a lot more to think about than simply making the next wave of fixtures - they may be playing a pivotal role in the world's well-being. Now more than ever, it seems that there is a more intense focus on lighting systems, exposure to natural daylight, building design and their major impacts on human health.


According to The Washington Post, issues with sleep, moodiness and staying alert can all be traced back to your exposure to light, and the way that buildings are constructed has a lot to do with it. Even though linear lighting design has become very advanced over the years and does its best to mimic solar rays, there is just no question that sun exposure can't be duplicated.

Affordable Architectural LED Lighting Goes Mainstream

Posted by Rob Gemmell on Jul 8, 2014 5:37:00 AM

 

The personal computer. Computer Aided Design. The iPhone. These are inventions that have changed the way that professional designers and architects work and create. For the most part, they have been beneficial to the built environment and paved the way for other innovations in this and related fields.


The light bulb is another invention that has evolved over time, and LEDs, the solid state electronic replacement for bulbs, are now clearly the big wave hitting the beach. However, the affordability of LED lighting has been a significant challenge to sell for lighting designers and architects - not to mention the general public.
