Excess lighting linked to bad moods

Specification of low profile lighting is about more than seamless integration into a building's architecture and energy efficiency, as new research shows cutting down on direct lighting is also linked to making occupants less grumpy.

LED light quality is kind of a big deal

Posted by Rob Gemmell on Aug 28, 2014 9:45:00 AM

 

Many people take their light quality as seriously as their morning coffee.

According to KNX Today, the task of specification has become less about what the fixture looks like and more about the light quality coming from it. As a result of individual point sources of LED indoor lighting, the beam of light distributed has become a bigger part of the design process and the structural components have become less so. In fact, companies like Vode Lighting have made it their goal to consciously minimize and reduce the lighting fixtures and related hardware. Lighting designers are not as concerned now about whether a pendant fixture has a brushed bronze finish as they are about how the light being presented can be used most effectively as part of the esthetic quality and functionality of a space.

While LED systems are suitable for providing uniform washes of light, they can also be used to create diffused glows just as easily as precise beams with less wasted light. This allows a designer to create wide ranges of effects from sharp contrasts between shadow and light to atmospheric looking spaces with little indication of where the light sources are.

LEDs becoming the darling of modern architecture

Posted by Rob Gemmell on Aug 20, 2014 7:50:00 AM

 

If there is one trend that we are seeing in the lighting industry, it is that LED lighting has finally worked out all of those hiccups, and is totally ready for the main stage. In fact, it is already happening among many lighting designers and architects across the country.

The "coming of age" moment is here for LEDs, as they have slowly crawled their way out of a niche market and asserted themselves as a viable source for large and small spaces. Architectural Record says that there aren't too many lighting problems that these fixtures can't fix, whether you are looking for a completely new, retrofit or renovation solution - indoor or outdoor.

Lack of Toxic Materials in LED Lighting and Human Health

Posted by Rob Gemmell on Aug 18, 2014 6:31:00 AM

 

Most consumers, lighting designers and architects already know that LED lighting is a fantastic option for energy efficiency, making Mother Nature and your bank account quite happy. However, one of the most underreported facets of LEDs is the collection of benefits that these fixtures can bring to our well-being.

In the past, the lighting industry had one goal: illumination. However, since LED and lighting fixture technology has advanced so far (and continues to become more and more innovative), many lighting manufacturers are creating LEDs that return the focus to health and wellness.

Improve physical and psychological health with tunable lighting

Posted by Rob Gemmell on Aug 12, 2014 6:17:00 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.

Set the tone on your creativity through lighting

Posted by Rob Gemmell on Aug 7, 2014 5:18:00 AM

 

The muses may have looked more like a light switch rather than beautiful ancient Greek goddesses.

Although dimmable LED indoor lighting doesn't posess any supernatural powers, a recent set of studies showed that it does have the capacity to inspire creativity. According to Medical Daily, German researchers found that dimming the lights is one way to prime the brain with darkness for creativity at work, in an art studio or at your home writing desk.

How LED lighting design can affect Circadian rhythm

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.
