Digital Elektronik is a service-oriented Austrian service provider in the fields of electronics and precision engineering with branches in St. Leonhard near Salzburg and Tamsweg. The company was founded in 1978 and is headquartered in St. Leonhard near Salzburg. In 1998, the subsidiary in Tamsweg was opened. Currently they are using KNX in one of their projects to control several lamps, which consist of several LEDs. The respective control of each LED is carried out exclusively via the KNX protocol and allows control of the entire system via a central computer. The large number of controllable lamps (> 350), or their LED composites, contributes to the complexity of the project, because all require a dedicated LED driver control.
