After a thorough market research, the Head of Development at German lichtwerk realized a market need for a large round surface mounted or hanging luminaire. He discussed the idea with the construction department, and the first prototype of the ciros luminaire was built.
“Imagine how elegantly it looks with a large luminaire in a diameter up to 1200mm either mounted or hanging from the ceiling, for example in a hotel reception,” says Dominik Wohlleben, Lighting Planner at lichtwerk.
To complete the ciros product family, a luminaire for office environments was needed, but lichtwerk had difficulties in meeting the German market’s very strict requirements to workstations. Therefore, special attention was paid to UGR<19 and Candela values as well as beam angles in the development process. In addition, it was essential that LED dots weren’t visible.
Solving the issue
lichtwerk is a subsidiary of Regiolux, and not only do the two companies share building and facilities they also share knowledge, so a colleague from Regiolux’ photometric lab mentioned that perhaps Ingemann Components had a solution to this issue.
“We got in contact with Ingemann Components’ German Office and initiated a dialogue. Even though we knew more or less what we were looking for, it was valuable for us to get Ingemann’s advice on the specific components. They were very quick at sending us product samples which allowed us to proceed with the development,” tells Dominik Wohlleben.
The ciros luminaire is a multi-layer solution consisting of a microprism and a film for glare reduction. Another element that was taken into consideration during the construction of the prototype was the distance between the LEDs and the optical lighting solution.
