Review of January’s Events
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.
