  • the luminaire base body is in this case designed for insertion of at least two light segments in these.
  • the total number of at least two or more light segments that can be inserted into the lamp base body are inserted for some applications in this, whereas for other applications by the user fewer light segments can be inserted into the lamp base body as the design of the lamp base body makes possible.
