Repro-light Consortium Concludes

Aldrans, Tyrol, November 2020 - The European research project Repro-light concludes after a three year journey which began in 2017. The consortium set out with the aim of supporting the European lighting industry in moving towards a more sustainable and competitive future. The project harnessed innovative technologies and materials to develop intelligent modular luminaires with matching smart production processes. The main components of these luminaires are interchangeable and configurable for the respective application (e.g. different LED modules and optics), and their software can be updated accordingly. The LED luminaire can change from a disposable object, into a customisable and sustainable product, with a high function value. Read more »

How to Increase the Efficiency of Two-Stage Drivers

In this article, Dr. Weirich from Infineon Technologies, describes a simple method for increasing the efficiency of drivers that can operate with LED engines with a wide range of current and power levels, at virtually no effort. In addition, the method allows for using smaller inductors in the buck stage, leading to lower cost and potentially, smaller size. Read more »
