Definitions

  • the lighting of a room can be of practical and / or aesthetic reasons Be meaningful. When lighting one for the stay of people furnished space, both of the aforementioned reasons may be relevant. With lights for subordinate rooms, e.g. Basement rooms or simple work rooms, is in the in most cases the requirement for good lighting of the space in the area of the workplace or the floor of the room. In contrast, when it comes to lighting Living rooms or representative rooms, e.g. Reception rooms, too on the aesthetic effect of the lighting.
  • Both directly and indirectly effective lights have become known which the lighting of the room indirectly through a boundary surface of the room takes place, e.g. a ceiling or a wall.

  • a luminaire for a subordinate room e.g. a basement or a simple work space
  • the latter applies especially for wet rooms, which in many cases are to be regarded as subordinate rooms are, and for which a good one with mainly low energy consumption Illumination of the room should be achieved.
  • lights that provide both direct and indirect lighting for the Enable space. Such lights do not have a closed housing, e.g. only one screen open at the top, so that the direct lighting through the Light emission cone downwards and the indirect lighting upwards through the in Screen arranged opening takes place.
  • Such and other lights with an unclosed housing are for in particular architecturally sophisticated rooms with a humid atmosphere not suitable, as a closed housing should be available in these rooms, to protect the at least one lamp of the lamp and to prevent others from getting moisture and contaminants e.g. Dust in that Housing can get into it.
