Fagerhult Lighting Academy at Intersect by Lexus

DUBAI. Fagerhult in association with APID has held an event at the city’s trendiest places, Intersect by Lexus. This unique event brought together architects, interior designers and lighting industry professionals to discuss the phenomena of light. Conversation was kindled by Henrik Clausen, the Director of Fagerhult Lighting Academy. Henrik spoke of the human aspect of light. “Light makes us recognise each other as living beings,” Clausen said. His talk called for deeper understanding of the effect of light in any environment on personal wellbeing. This visionary approach supported by the academic research in Denmark results in adoption of new standards by manufacturing and consulting community and novel methods of controlling light.

Creepy post on visual images

“Color is the keyboard, the eyes are the harmonies, the soul is the piano with many strings. The artist is the hand that plays, touching one key or another, to cause vibrations in the soul,” said Wassily Kandinski, famous Russian abstractionist artist. The video above is an illustration to this, or is it?

Dr Jack Gallant from University of California, Berkeley, has created a library of images generated in peoples brain during watching hours of random footage in his lab. Guinea cinefiles were put into magnets of MRI scanners, and activity inside their head was meticulously recorded. Geeks will like it: the lab experts coded a so called movie-to-brain mathematical model predicting brain activity evoked by novel visual imaging.

… and I thought I was the one having trouble recognising people’s faces.

If Light Is Not What You Expect

radiation-law
DUBAI, UAE. A question from a client has recently prompted to digg into a question why dimming LED does not feel like dimming conventional halogen spotlights. They have refurbished a restaurant and replaced spotlights with halogen lamps to LEDs. The effect did not impress: instead of warm ambience the client got pale dull environment.
The phenomenon of warmth in a dimmed halogen lamp is achieved through cooling down the tungsten filament. Less current passing through it gives out a redder spectrum of the light. Naturally we are expecting warmer hues from lesser light!
LED light source uses a different physical mechanism: electroluminescence. Halogen lamp is still incandescent in its nature. There is no major change in the color of the light when the current passes through an LED die. This change, in fact, is not discernible to the human eye. The color of light in an LED depends on the chemicals used to coat the LED die, and not on the thermal radiation.
Hope we have not yet lost you by the fourth passage. Because here is the good news:  the industry has a solution to offer. LED Engin from the USA has developed a light source which combines several dies driven separately which helps to imitate a shift from 3000K to 1800K (your incandescent lamp is 2700K, and your candle is 1700K).
