The initial situation:

As a regional energy supplier, Syna GmbH operates street lighting in numerous towns and municipalities. In the historic old town of Oberursel in the Hochtaunus district, the sprawling city center with its characteristic half-timbered houses was previously illuminated by historic lights.

Most of the existing luminaire housings were in good structural condition. However, the lighting technology installed no longer met current technical, energy, and lighting design requirements. Against this backdrop, the decision was made to professionally renovate and convert the historic luminaires to modern LED lighting technology.

The customer’s wish:

As a specialist in the restoration of historic lighting fixtures in accordance with preservation guidelines, BRAUN Lighting Solutions was commissioned to refurbish 226 old town lights.

The requirements included:

• Complete dismantling of all luminaires
• Sandblasting and refurbishment of the cast housings
• Professional disposal of all old electrical components
• Return of materials to the recycling cycle
• Painting and complete reconstruction of the luminaires

The aim was to renew the lighting technology within the existing historic luminaires in an energy-efficient manner. The new lighting was to ensure glare-free illumination of the traffic lanes and sidewalks while achieving energy savings of well over 50% compared to the previous HQL lighting.

Our solution:

The technical conversion was carried out using the His.lux® Universal Module 4 in LED gas light version, which we developed and produced in-house. This module creates an authentic gas light look and combines historical lighting effects with state-of-the-art LED technology.

The light color was individually tailored to the client’s requirements. The historic round reflector was handcrafted using traditional methods. The system was supplemented by a BAMAG remote igniter housing with an imitation brass burner tube, which allows for centered cable routing that is not visible from the outside.

The visual appearance of the luminaires is therefore almost identical to the original gas-powered versions.

Other luminaires within the project were equipped with the cityLED II CoB module including an anti-glare ring. The use of special secondary optics enabled the required symmetrical light distribution to be achieved with precision.
