Luminaire 120°



#StudioIndustrialDesign #Master-Thesis

Optimal light conditions for interior spaces require a delicate composition of light quantity and light color which adapts to the natural course of the day. The luminaire «120°» sets the user in the right light for 24 hours. It provides cool light for an active day and prepares for the night with the dynamic and subtle change to warm white light towards evening. Since humans perceive lighting intensity differently, the brightness can be adjusted via touch-free sensors. The luminaire cases are designed as glare-free, minimalistic encapsulation of the LED light sources.

Assessing lighting purely based on light color or lighting types allows for assumptions about the light quality, but changes as soon as the space is included as a further factor and changes again when the user and application come into play.

In her Master's thesis, Rahel Stacher deals with the impact of light on humans. In particular, she examines the intersections between the user, the product and the possibilities of new lighting technologies. Stemming from questions like: «What is the best light? What influence does light have on us humans? What are the requirements for light? What is needed to enable the user to adjust and optimize the lighting that is optimal and stimulating?» Rachel Stacher develops a lighting solution for interior spaces, which take into account the melanopic effects of light. Based on recent scientific findings, «120°» provides the user with optimal and efficient light conditions with as little material consumption as possible.
