thePrema Presence Detector
One of the goals of energy-efficient building technology is to ensure that rooms are only lighted, ventilated and heated when they are actually occupied. Modern buildings can achieve this through the use of presence detectors. Created by Theben HTS, the market leader in presence detector technology, thePrema is a product family for presence-based lighting and climate control that has already won several awards. Helbling’s role was to develop the entire optical system.
Helbling was commissioned by Theben THS to develop a total of four optical systems for a new family of movement and presence detectors (thePrema and theMova). The biggest challenge was that all optical systems had to share the same external dimensions. At the same time, a performance level was needed that was at least on a par with or even exceeded that of comparable products. Under these circumstances, the design seemed unmanufacturable due to its shape, size and wall thickness. Yet Theben HTS had turned to Helbling for a reason. Helbling`s optics specialists work side by side with plastics experts. This puts them in a position to solve seemingly unsolvable problems.
