Philips Lighting not only illuminated the entire art collection with LED lighting, we also illuminated the whole exterior of the building with LED. And the Rijksmuseum is no small building — looming over the Amsterdam horizon with unparalleled majesty on … Continue reading rijksmuseum: exterior lighting
The History and Science of Color Temperature from FilmmakerIQ.com on Vimeo. Via Gizmodo, here is a well-produced video explaining the basics of color temperature. I highly recommend this for anyone just starting out or interested in the basics of light. … Continue reading the history and science of color temperature
The US DOE just issued a fact-sheet addressing the blue-light output of LEDs. It is a very good read for anyone concerned about this topic. The following two images are the crux of the document. The first chart shows the … Continue reading no, LEDs do not produce more blue light, so get over it
The Solid-State Lighting group at the US DOE just sent out an email with an excellent summary of the measurement standards already in place or currently in development for LED lighting. Here’s is an abbreviated version: “…we now have such … Continue reading DOE SSL standards update
Available in 4 parts via YouTube, here is a great BBC special featuring the reopening of the Rijksmuseum, hosted by Andrew Graham-Dixon. Although this video doesn’t specifically address the lighting, I highly recommend it. The entire collection is illuminated by … Continue reading rijksmuseum: BBC special
Everyone in the lighting industry knows Richard Kelly’s “three elemental kinds of light”: Focal Glow (make it easier to see) Ambient Luminescence (make surroundings safe and reassuring) Play of Brilliants (stimulate the spirit) However, few people have ever read the … Continue reading richard kelly’s six qualities of light
Thomas Schielke, who is in the communications group at ERCO and has spoken at many events and seminars, has a personal site with many interesting research videos for those of you who are “lighting nerds”…like myself. Above is an excellent … Continue reading history of luminous walls
Following up on the Dezeen video, my colleagues at Philips Lumiblades will host a webinar regarding OLED tech on January 22nd. Mark your calendars…the future of lighting…in a Powerpoint! Continue reading philips lumiblades – webinar
Here’s your lighting vocabulary word-of-the-day, and I’m betting that even if you’re the most hardcore lighting nerd, you haven’t heard it yet: Chromophore. According to Wikipedia: A chromophore is the part of a molecule responsible for its color.  The color arises when a molecule absorbs certain wavelengths of visible light and transmits … Continue reading word-of-the-day: chromophore
If you can get past the freaky intro, this video contains some nice information about the history of LEDs and a very cool lab experiment demonstrating how a raw silicon carbide crystal glows in different regions when electrified. Silicon carbide … Continue reading make magazine: the led
I found this terrific research piece by Margaret Maile Petty, a professor at the Victoria University of Wellington in New Zealand, called “Perpetual Noon: Fluorescent Lighting and the Modern Office“. Apparently she wrote this piece during her time at Parsons in New … Continue reading perpetual noon: fluorescent lighting and the modern office
Check out this great TED Talk: Ramesh Raskar – Imaging at a trillion frames per second http://on.ted.com/h42N Ramesh uses a new technique called femto-photography that is so fast is captures beams of light traveling in mid-air; aggregating the photographs into … Continue reading Femto Photography: Capturing Pulses of Light
Sometimes, life really surprises and delights you. Bobo Explores Light is an amazing educational iPad App that teaches children — and frankly, most adults — about the fundamentals of light. And the amazing thing: This is one of the best … Continue reading bobo explores light
HyperBody is an interesting research group, led by Kas Oosterhuis, under the Faculty of Architecture at the Delft University of Technology. HyperBody is researching various forms of interactivity within architectural design: “The goals set for the group’s research are to … Continue reading hyperbody
Atmospheric Optics is a cool site showcasing all of Mother Nature’s delightful anomolys in the sky. The site has terrific simulations and detailed explanations about how the optical effects work, such as the classic crepuscular rays above. Although it is … Continue reading atmospheric optics
Math and I don’t get along all that well, even on simple formulas. So that is why I love this “rule of thumb” from Wikipedia: “Doubling the distance reduces illumination to one quarter” Continue reading inverse square law (so you can remember it!)
Brilliant: The Evolution of Artificial Light by Jane Brox, is absolutely…well, uh, I just can’t resist…must not type this pun….brilliant! I highly recommend reading this book to anyone…super-mega-lighting-dork or not. Brilliant really goes beyond just lighting: It looks at the evolution of human history as filtered by the powerful effect that man-made light has had on our civilizations. The research that the author did is amazing; you will continually be blown away by the detailed historic tidbits sprinkled throughout. It’s a terrific, fast -reading book…really fun. Continue reading brilliant: the evolution of artificial light
Above is a rendering I made to help explain a basic way to categorize light sources. Lighting can be broken down into three fundamental geometric categories: point sources, linear sources, and planar sources.
Now, we don’t live in a conceptually perfect Euclidean world, and the perception of relative scale of course matters in how one defines a certain light source. What is approximating a skinny “line” of light at a far distance resembles a rectangular plane of light at a near distance, so context is essential in these categorizations.
A direct result of this relative scale perception issue is that when points, lines and planes are aggregated together in clusters, they create visual textures across a meta surface. Let’s call these the “3+1” fundamental geometries of lighting.
It appalls me to see how many blowhard crankpots are hiding behind the tenants of “personal freedom” and “liberty” and trying to actually reverse the residential energy efficiency standards enacted in 2007. I mean, come on…it was the one good thing Bush Jr. did for the environment!
The really twisted part is that history is sadly repeating itself. Like clinging to their glory days of long-gone youth, some people just can’t let go of past technologies. Did you know that people actually bemoaned the passing of gaslight in favor of electric light?
SEED Magazine has an interesting piece on bioluminescent organisms. One paragraph in particular reads like Mother Nature’s version of interactive lighting control: “Their lights have a variety of purposes: Camouflage, attracting mates, attracting (or distracting) prey have all been observed. In animals with nervous systems, in most cases, neural activity initiates the bioluminescence. But in the velvet belly lantern shark, Lynn says, researchers found that the glowing was not caused by nerve cells. Instead, it seemed, certain hormones controlled the glow: Melatonin and prolactin turned it on, and a hormone called Alpha-MSH turned it off. This makes some sense, as … Continue reading SEED Magazine: The Evolution of Illumination
