This luminaire was developed individually in the second semester, also as part of the „COLLABORATE“ project. The focus was on the students‘ own needs at their workplace. Through research at the beginning of the project as well as the own experience, the important role light plays in a working space became apparent. Often there is no sufficient lighting or only a single strong light, causing a strong cast shadow, which disturbs while drawing or writing. In such cases, indirect light reflected from walls and ceiling is usually more suitable. In large rooms, however, it is often not as easy to produce sufficiently strong indirect light, depending on the position and distance from walls and ceiling. The concept therefore includes a large height-adjustable reflector surface that makes it possible to create pleasant indirect light regardless of the appropriate environment.
