RZB Leuchten was founded by Rudolf Zimmermann in Bamberg Germany at the beginning of World War II, in 1939. Initially the company manufactured circuit breakers, fuses and junction boxes components as well as porcelain luminaires.
Production of all-glass luminaires begins in 1948. At the same time the export to other countries takes a start. The introduction of RZB’s pioneering rapid attachment system for all-glass luminaires, known as DKN system, a push and tilt system has started in 1960.
In the years that follow the RZB family business continues to expand. In 1987 RZB begins partnering with the famous Italian light company Reggiani S. p. A. of Monza and Rome in the field of low-voltage luminaires. The cooperation ended in 2007.
