January
eLearning: The webinar on LED lighting was well
attended and packed a large amount of information in a short
presentation.
It was supposed to cover operating principles of light-emitting
diodes, principles of human vision, planckian sources,
photometric and radiometric quantities, color rendering and the
color-rendering index, and areas for present and future
applications of solid-state lighting devices.
Unfortunately the network hung at about the one-hour mark and we
did not get the later few portions of the webinar. I
learned that there are many areas to improve LED lighting,
including improving efficiency and lowering cost. LED
lighting is now already a cost-effective technology, and will
improve many-fold over the next decade.
January Section Meeting and ETC
Tour: The evening was attended by over 35 people.
The meeting started with a period of appetizer and networking in
ETC's impressive commons. Ingrid McMasters then gave an
interesting talk from the perspective of a "lumen geek" rather
than a "photon pusher", showing many of the considerations of a
lighting systems designer. Ingrid brought an impressive
array of lighting fixtures showcasing what is possible with LED
lighting. In addition, ETCs well-lighted performance stage
was able to accent the effects of color temperature as she
lectured about it, The tour was led by Heather Robbins and other
colleagues, starting in the stock storage area, lit by
innovative area lighting. ETC also projected warning signs
directly on the floor, eliminating the need for painted
lines. The tour then visited the automated manufacturing
area where systems were built, tested, and burned in. The
tour ended in the metal forming area where sheets of metal were
automatically stamped and formed for the lighting
assemblies. The ETC tour showcased an advanced
manufacturer employing local people and automation to dominate
an industry with competitive products.
