Depending on the type of light, the bulbs can be partly switched on or off separately from each other or separately. Furthermore, suspended luminaires, in particular for installation on dining tables are known. These usually have only a single (lower) surface side associated with bulbs that are either only on and off and dimmable in comfortable lamps beyond.
  • suspended luminaires Due to the static color temperature of their light sources, particularly known suspended luminaires have the problem that they are not designed to be adaptable to the daily different life situation or, as a rule, optimized only for a life situation. For example, to do paperwork, like homework, a cold white light is more needed, whereas in the evenings, a neutral white or warm white light would be more preferable. These different requirements or wishes can not be met by standard pendant luminaires. Particularly unsatisfactory are known suspended luminaires in the event that one of the ambient lighting and different table or work lighting is desired.
