On stage at Euroluce 2017 the first and only representation of the night sky... indoors

The Moon, enchanting muse for artists of all times, is present at Euroluce 2017.   CoeLux®   Moon, first and only technological indoor representation debuts in the 29° edition of International Lighting Exhibition.

Savoring a glass of red wine and enjoying a candlelit dinner in the moonlight, fall asleep in the fascinating atmosphere of the night light, experience the peace and tranquility of the universe indoor. This is the emotion   CoeLux®   Moon. Always. Whenever there is a need to enter in contact with the universe and to stop the time even when outside the world runs.   CoeLux®   Moon  demonstrates how the ability of artificial light for generating comfort and relaxation is comes from delivering the experience of an infinite space, even before illuminating. The comfort produced by   CoeLux®   Moon, in fact, is not lower than the one generated by the systems CoeLux®  which reproduce the sun in the sky, although the intensity of the light is here thousands of times less.

We started to write a post about some of the most exciting research ideas in lighting - written together with Deborah Burnett of Benya Burnett Consultancy ( http://benyaburnett.com/ ) - and it grew into a full-fledged article.  After talking with Laura McDonald Stewart - who you know as the Owner/Founder of Plinth & Chintz: Interior Design Blog & Industry Resource and Show Manager & PR/Marketing Director of the very successful Dallas METROCON Conference  - she agreed to publish the article on her Plinth and Chintz website.  So, please take a look at the resources available there and for our article entitled Just When We Thought We Knew Lighting

As a perfect segue for what we want to write about next, in proofing the prior blog about the Dutch Scientist, our friends at CoeLux told us about the Artist - James Turrell also being a fan of the same book by Minnaert.   This is an inspiring video done right here in Texas at Rice University in Houston.  As we delve into some of the reasons for making the lighting in our homes and businesses more like nature, this artist provides very compelling reasons for doing so.  To view the YouTube, please click on the picture above.

In 1937 M.G.J. Minnaert published the first edition of his book entitled Light and Color in the Outdoors . This became a significant backdrop for the development of the CoeLux® artificial skylight systems. The book elaborates upon the fact that so much of what we see is biologically determined by both how our eyes see and by how light and the atmosphere affects what we see. Consider this quote on pg. 133 of the latest 1993 edition from none other:

“Green and blue are invariably accentuated in the half-shadows; yellow and red and white in the lighter parts” - Leonardo da Vinci, Trattato

Furthermore Mr. Minnaert describes on the same page:

“If you can find a red and a blue in a picture gallery that appear to be equally bright by day, you will see that, in the twilight, the blue becomes by far the brighter of the two, so much so that it seems to radiate light.

These are examples of the Purkinje effect. It is caused by the fact that in normal illumination our eyes observe with the cells in the retina called cones, but with the cells known as rods in the very weak illumination. “

Through examples too numerous to expound upon in one article, we also find that the colors in the atmosphere are the result of light scattering of the sun’s rays in atmosphere, at elaborated in Lord Rayleigh’s Laws on p. 263. From here we see that there is also a biological interaction between the sunlight, the mix of particles in the atmosphere and the angle (or length of atmosphere in which sunlight travels) of the sun during different times of the day. Because of this, during the middle of the day we see is “sky blue” (which is actually more violet in color than blue, but because of our eyes we see more blue) and later towards the end of the day we see more yellow and red colors.

This is, in large part, why Professor di Trapani (CoeLux’ founder) chose the path of using nanoparticles to accurately reproduce the same sun and blue-sky; since, this biological solution allows

1.      a more faithful replication of how the sunlight and blue sky and

2.      allows the biology of our eyes to see the sky we’ve known since birth.

Bottom line, CoeLux® is using the equivalent of 10 kilometers of atmosphere in a fused “window” panel for producing the same Rayleigh light scattering we see on sunny days outside; and are reducing the scale so that it will fit in your home or commercial applications.

Please stay tuned for our next article where we explore how what we’re learning about the Circadian System may benefit from what we know about CoeLux®.

The implementation of CoeLux® technology in any environment - whether in a commercial or residential installation - is enhanced with the design and use of the latest tunable LED technology as well.  Taking a step back and looking at the fact that the CoeLux® rendering of the sun and blue sky so realistically mirrors the real sun and blue sky, considering how this changes lighting design is appropriate.

Koa Technology Group has chosen to represent Colorbeam for the following key reasons:

  • Low voltage UL certified class 2 lighting solution
  • Powered and controlled over a single CAT cable
  • Flicker fee 0-100%
  • Delivers whites to any Kelvin on site
  • Enhanced mood settings via full RGB lamps
  • Energy efficiency
  • Single cable installation efficiency and lower cabling costs
  • Integration into complete automated technology system
  • Built-in IP addressable Gateway control   

Balanced lighting incorporates consideration of color temperature and intensity.  Using the images above as dramatic illustrations, the image on the left shows a room where no additional surrounding lighting is used, and the effect of the CoeLux® artificial skylight is very pleasant.  If, on the other hand, this was in an office environment where more light in the back and corners of the room is desired, we can add lighting as illustrated in the middle picture of the same room.  However, in this middle example, one will note that the white tuning is not exactly matching the CoeLux® and the intensity of the light is eliminating the sense of contrast and definition we have present in the image on the left.

While our illustration in the middle shows how important correct lighting intensity is, our room on the right is a dramatic example of how color temperature is important.  While this is perhaps what is desired for mood or entertainment events, it shows how the CoeLux® sunlight effect is essentially negated.  

Bottom line, regardless of the lighting systems employed, your professional architects, interior designers and lighting designers have more tools for creating more of what your project needs with these new technologies.

Technology today can seem like a journey that is much like "trying to see the forest for the trees".  So much is new with technology enabling new and different paths, there is a need for technology partners who can help, who also have an established history of doing just that.  The members of Koa Technology Group have worked together for over 20 years in establishing new technologies and markets; including, the latest new technology for high-end residential and commercial applications.  

For example, new advances in nanotechnology from CoeLux ® a llows us to reproduce an artificial sun and blue sky - that turns on and off - which rivals the actual sun and blue sky.  This is what began the efforts and alliance of personnel behind Koa Technology Group.  Now a new era of LED and low-voltage tunable lighting systems available through Colorbeam, is also re-writing how many think about lighting and design, altogether.  
After providing several training sessions regarding lighting design and implementation of CoeLux®and Colorbeam®for many professionals in the Design and Technology Communities over the last few months, it's clear that we need to keep the dialogue going.  New ways of thinking oftentimes require a few passes at different aspects before it begins to become "our own"; in a way that we feel comfortable and confident in implementing these new solutions.  

Lastly, we consider this an area of technology for which the book is just now being written.  Our hope is to use this site and blog as a coalescing point and methodology for communicating important new insights and updates, as we discover them; whether, from our own experience or from manufacturer, design and client partners who'd like us to pass on new information.
