copper percentages for its FR4 boards. Traditionally, FR4, a glassreinforced, epoxy-laminate material platform widely applied in inexpensive electronic products, isn’t suited for optoelectronic devices. But, when the copper percentage is increased to achieve highperformance thermal results for LED lamps, it becomes fairly expensive, even with the FR4 boards. Haeusermann specializes in industrial electronics, control, measurement and instrumentation technology, electronic manufacturing services, medical technology, telecommunications and entertainment electronics. • Ospira GmbH’s (Weingarten, Germany) Dr. Dirk Hansen presented information on characterizing polychromatic LED systems (RGB-based, LED-pixels for electronic message centers) with goniophotometric measurements along with color filters and raydata simulations. Goniophotometry is the technique used to measure the angular distribution of light as it scatters from an illuminated surface. Ospira develops optical systems and offers optical-measurement services. Such measurement and simulation tools can help design LED lamps with optimal emitting areas for illumination applications, while minimizing the viewingangle dependence. • GL Optic exhibited more than 10 different photometric and spectroradiometric instruments for characterizing various lamps, including retrofit LED lamps. Its integrated spheres accurately measure LEDs’ thermal-transient behavior, an important factor for characterization of high-power LED lamps. GL-Optic, which has an R&D center in Poland, is a subsidiary brand name of Just Normlicht GmbH (Weilheim Teck, Germany), a 42-year-old, lightingequipment firm that has worked with Fuji, Agfa and Kodak. n
