Company history

Since 1977, our company has revolved around illumination. Since the change of company name to planistar Lichttechnik GmbH in 1990, this has been our exclusive focus.

  • Museums
  • Exhibitions
  • Trade show booths

2 m high illuminated columns for Hugo Boss

2000

Development of new markets:

  • Industrial image processing 

Establishment of a separate “Industry” product group. Our luminous surfaces were adapted to the needs of a new clientele. Step by step, a large product range was built up. 

With the growth of new markets, a new building was created, which now houses its own sheet metal processing and an acrylic laser. Screen printing was supplemented with a larger semi-automatic machine. 

Initially, the luminaires still used fluorescent lamps. Later these were replaced by high-performance LEDs. The housings, lighting technology and control systems were developed and manufactured by planistar right from the start. This allowed us to optimally adapt the luminaires to our customers’ requirements. 

2010

Increasing integration into industry

Expansion of the machine pool with a UV plate printer. Now it was possible to produce optical fibres in small batches and individual pieces. 

  • Expansion of a lower-cost Sled series and a high-quality Xled series
  • Development of machine and workplace luminaires
  • Updating the light boxes with LED technology
  • Winning over of many regular customers who are loyal to this day

2015

  • The office wing and the assembly section were gutted and completely rebuilt.
  • Ergonomic workstations for comfortable working
  • New PC equipment for archiving and communication
