Tech-Talks BREGENZ: Martina Paul, General Secretary, CIE (Article published in LpR #43)

Martina Paul With the rise of LEDs as the future lighting technology, the relatively stable lighting industry faces many changes and challenges. One of the main challenges is the ever increasing speed of transitions, something already seen in the semiconductor business. Standardization organizations are facing similar challenges. On the one hand they should define standards that will last as long as possible and on the other hand the standards need to be as clear and precise as possible. Martina Paul, Secretary General of the most important standardization body, the International Commission on Illumination (CIE) was invited to the Tech-Talks BREGENZ to discuss these topics.

Target Group-Adequate Lighting of Shop and Retail Areas – New Retail Study by Zumtobel

Figure 1: The group STIMULANCE (Hedonists, Adventurers), responded most positively to lighting scenes with relatively strong contrasts, created by accent lighting and a variety of different spots (Photo credits: Zumtobel) n a laboratory study conducted by Zumtobel and Gruppe Nymphenburg it has been possi-ble for the first time to measure people's affective responses to various lighting scenarios in shops on an empirical basis. In the process, the lighting preferences of seven different groups of customers were analysed using a neuropsychological target group model. The findings of this study will help to develop lighting concepts for retail, to present goods per-fectly and to increase the customers' sense of well-being, thus making them stay in the shop longer.

"Beyond LM Testing - A New Metric for Quality over Lifetime" by Thor Scordelis

Testing laboratory In a recent blog post, the United States Department of Energy’s Jim Brodrick noted that solid-state lighting standards and testing methods “may not be glamorous, but they’re essential for the success of any technology, and SSL is no exception.” Certainly, this is true with respect to lumen quality, and for many years, the LM-80 standard, used to measure lumen maintenance of LED packages and modules, has sufficed. However, with the growing adoption of LED technology has come higher customer awareness and expectations. “Good enough” isn’t good enough anymore. Read more »

Two-Switch Flyback Solution for LED Street Lighting

Won-Seok Kang has worked for Fairchild Semiconductor since 2006 and is currently an Industrial Senior Application Engineer for Fairchild’s Switch Mode Power Supply in the Power Conversion Division located in Korea. His research interests are in functional power module, LED drivers, resonant and soft switching dc/dc converters, and electronic ballast. He has a B.S. and M.S. degree in electronics engineering LEDs provide high efficiency and long life compared to conventional lighting sources. Therefore, they are becoming first priority of lamp types to reduce energy consumption for internal or external lighting. This is also the case in street lightings where better efficiency and longer life are essential for less cost. A switching power supply designed to power up LED lamp should also have high efficiency and robustness to assure maintenance free lifetime as long as LED lamp. Resonant converters are one of the most popular power supply topologies here since their performance delivers increased power efficiency. LLC resonant converter has drawn attention thanks to its features such as high power conversion efficiency and low voltage stress on secondary rectifier. However, complicated design and high manufacturing cost of LLC resonant converters have been obstacles to fast time-to-market and cost reduction. Another problem of LLC resonant converter is large circulating current that is required to maintain zero voltage switching (ZVS). It causes relatively high power consumption at light load. LLC resonant converter also has potential failure issue when MOSFET with poor body diode performance is used. Two-switch flyback converter is proposed as an alternative solution to overcome the limitations of the LLC resonant converter. With additional switch on the high side, leakage inductance energy is clamped and recycled back to input to improve efficiency. The dissipative snubber circuit is no longer needed. A 120W rated switching power supply is designed utilizing two-switch flyback topology. The details of design specification and test results are presented. Read more »
