Electronica 2010, the world's largest electronic fair, was hosted in Munich from November 9th to 12th. It was remarkable to see how diverse LEDs and related applications, as well as supplementary components were presented at the fair. The progress of LED components in parameters such as efficiency, CRI or thermal resistance is ongoing. There is now an LED with 160 lm/W in cool-white available on the market! Single LED packages derived from LED strings reach lumen output values of some 1,000 lumens. In addition, a range of package alternatives are available; optimized for explicit purposes like automotive headlamps, spotlights etc. Like at L&B, at electronica, component manufacturers offered system solutions such as bulbs, fluorescent replacement LED lamps or street-lighting headlamps, to name only a few. The rapid diversification of the lighting marketplace is a continuing process and a number of companies not only offer solutions, but have also formed their own planning services and distribution channels to penetrate the market. Another trend could be seen as well. LED lighting systems are increasingly linked and integrated with intelligent controls. The strategy of many semiconductor IC manufacturers is to focus on LED lighting. The " new semiconductor load – LED " is much easier to manage than, for example, a discharge lamp with its complicated behavior. The field is therefore now ready for semiconductor specialists to bring their expertise into LED systems. These companies combine their vast experience in IC design with LED technology. Some examples shown at electroncia were related to modern communication methodologies such as power-line and wireless communication while others presented intelligent LED controls to optimize thermal management. Some of the articles in this issue of LpR cover intelligent control schemes for improved performance. All in all, it was fascinating to …
