RIDI Group has grown dynamically in recent years. Not least due to the acquisition of Spectral and the interior lighting portfolio from Selux. RIDI Group has significantly strengthened its project and key account business. At the same time, technology and markets are changing faster and faster, and technological change will have an impact on all areas of the company.

In order to be able to face these challenges even better and faster in the future, Dietmar Zembrot joined the company as Technical Director of the RIDI Group on July 1st. Mr. Zembrot is a lighting technician and has many years of professional experience in various international lighting companies. Most recently, he was CTO of the Trilux Group.

Richard Diez is a self employed electrician in Jungingen, near Stuttgart.  

The so called post war ‘economic miracle’ was in full swing and business flourished and more employees were hired.

During the winter months business slowed and Richard Diez had a briliant idea!  In order to keep his employees busy he started producing a kitchen light, the A1.  Initially produced using bought in elements, quickly he bought in machines to make the manufacture independent.

The kitchen range was supplemented by living room lights and the company grew, moving into buildings near to the original house, and now the site for the main manufacturing facility.

Contacts were made with the wholesale trade which remains the bedrock of the sales strategy of RIDI in Germany.  The foundation for the success and growth of RIDI Lights and RIDI Group was laid.
