According to Lux Magazine: Neuroscientist professor Russell Foster…led the team at Oxford University which discovered the eye’s third photosensitive cells, creating a whole new paradigm in interior lighting. Previously unknown to science, the cells hold the key to our understanding … Continue reading russell foster
I found a fantastic PPT that looks like an academic lecture covering the pioneering mid-century lighting designer Richard Kelly. The slide deck contains an especially impressive range of photos of Kelly’s projects that are not commonly available on the web. The … Continue reading richard kelly – powerpoint deck with rare images
For us lighting nerds, a terrific webinar hosted by the US DOE discussing the state of the actual scientific research on street lighting and sky-glow sources, versus the extreme scare-mongering of recent “scientific” publications: Bruce Kinzey of Pacific Northwest National Laboratory … Continue reading US DOE street lighting “get the facts” webinar
I’ve advocated in many forums that embedded lighting, particularly fusing patterns of light into architectural wall and ceiling surfaces, will become a major trend going forward, especially in office applications. My theory is that in natural settings we humans are instinctively … Continue reading using embedded lighting in office environments
Check out my posting “Layers of Eye Candy” on Philips Lighting’s Future of Light blog where I explore using layers of embedded lighting in retail applications. Continue reading layers of eye candy
Wandering around the National Air and Space Museum last week, I found what is arguably the coolest light meter ever: The Minolta Space Meter used by Neil and Buzz on Apollo 11 to set exposure settings for their photography while walking … Continue reading the coolest light meter…ever!
I’m still amazed that after about 20 years specializing in lighting, I can still learn new things that lighting does. Today’s crazy new thing: Photoacoustic spectroscopy. Basically, light has enough energy in it to cause material to vibrate, generating acoustic signals that can be measured. I find this interesting because I’ve felt the affect first hand – holding my hand in the beam of a super powerful, crazy-narrow beam LED fixture (which doesn’t have any IR or UV energy in the beam), you can feel the power of the photons. Mostly what I felt is probably thermal absorption in my skin, … Continue reading lighting geekery: photoacoustic spectroscopy
This summer, go ahead and get half naked and prance around the beach/pool deck/music festival. The sunshine is good for you in so many ways…it gives you energy, relaxes pain, keeps your skin healthy…and lighting science is just beginning to … Continue reading tan your bum this summer…it’s good for you!
Can you see what is wrong with this picture of my work space (at an undisclosed Amsterdam company)? No? You can’t see what is wrong? Now granted, mobile phone cameras have no where near the adaptability of the human eye, so … Continue reading european office lighting is too bright for my eyes
For hard-core lighting designers: A very detailed description of daylight simulations, from Ian Ashdown, the Chief Scientist from Lighting Analysts, Inc., one of the two industry leaders for lighting simulation software (maker of AGI32, which is popular in the US). http://agi32.com/blog/2016/03/26/climate-based-daylight-modeling/ Continue reading Climate-Based Daylight Modeling | All Things Lighting

The IES has put forth a new color metric standard that is far more comprehensive then the old CRI (Ra) measurement system. It will take time, but I hope manufacturers and specifiers alike adopt the new system. For a more in depth discussion, check out this Architectural Lighting article. Below is the information from the DOE SSL Postings email: A New Method for Evaluating Color Rendition The Illuminating Engineering Society (IES) has just published an important technical memorandum, TM-30-15, which outlines a new system for evaluating the color rendition of light sources. It was developed by an IES task group that … Continue reading TM-30-15 color measurement standard
I’m presenting a 90 minute session at the upcoming Lightfair 2015, titled “Embedded Lighting: The Future of Integrating Lighting into Architectural Systems.” My session brief: Lighting has historically been fragile, dangerous, objectified. Yet new technologies are being developed to permit lighting … Continue reading lightfair 2015: embedded lighting
Interesting article in Treehugger posits that exploding global rates of myopia – nearsightedness – might be caused by children’s lack of exposure to daylight. Here’s the punchline: While some researchers think more data is needed to confirm the theory, animal experiments further support the idea that being outdoors, and exposure to the light that comes with it, is protective. The leading hypothesis, explains Dolgin, is that light stimulates the release of dopamine in the retina, and this neurotransmitter in turn blocks the elongation of the eye during development. Based on epidemiological studies, Ian Morgan, a myopia researcher at the Australian … Continue reading nearsightedness and daylight
I recently read Steven Johnson’s fun new book “How We Got to Now: Six Innovations that Changed the World“. Of course, Johnson claims one of those six critical innovations is artificial light. Johnson references a very interesting study from Yale … Continue reading william nordhaus: the historic cost of light
I will present a talk on the “The Evolution of Adoption” for LED systems, considering what innovation possibilities lie in the convergence of Connected Lighting, Embedded Lighting, and Sustainable Lighting, at the SSL Ecosystem Conference, September 23, 2014, at the Cambridge … Continue reading SSL Ecosystem Conference
Check out the new fact sheet published by the DOE. It helps to clarify and dispel some of the myths surrounding LED lighting and its impacts on health. I think this paragraph is the perfect summary: What may be beneficial for an occupant during the day may be harmful at night, and may vary significantly between individuals in a given space. Complicating things even more is the need to balance the desire for alertness with preservation of normal circadian rhythms among night-shift workers, for example. Therefore, even if a prescription for effective nonvisual stimulation is developed, implementing the solution may … Continue reading U.S. DOE releases new fact sheet on light + health
The folks at the Edison Report Europe have summarized the presentations at last week’s Strategies in Light Europe event in Munich, including a tidy summary of my presentation “The Paradox of Standardization“: Brad Koerner (Philips) gave an overview of the present design practices and tools in architectural lighting. He made a plea to provide information on SSL lamps-luminaires and modules in a way that it can be directly imported in the software tools used by lighting designers and architects. He showed an interesting example of so-called on site manufacturing of luminaires using Zhaga compliant SSL modules where the luminaire was basically … Continue reading edison report: SIL Europe – the paradox of standardization
Thanks to everyone who attended! In case you missed our presentation last week at PLD-C in Copenhagen, here is the slide deck that I presented along with Rogier van der Heide and Juliette and Sjoerd from BeersNielsen: 20131104_BradKoerner_PLD-C_IlluminatingTheRijksmuseum Continue reading rijksmuseum: PLD-C case study slides
