Definitions

  • the invention relates to a floor lamp, in particular for Illumination of computer workstations.
  • the invention has for its object a floor lamp for a group of two desks to indicate the a glare-free illumination of the two within the Two sets of work tables that can be aligned as required and also contributes to room lighting.
  • the object of the invention and solution to this problem is a Floor lamp with stand, cross bar placed on the stand and two lamp heads attached to the cross bar, the lamp heads having at least one elongated light source, Side reflectors, a translucent floor and have a top prismatic glass cover and on one longitudinal end about a vertical axis of rotation are pivotally connected to the cross member.
  • the lamp heads are at least 180 ° in the horizontal swiveling. As a result, they are at any angle to each other alignable.
  • Compact fluorescent lamps are the light sources prefers.
  • the translucent floor is for example, as a perforated floor or lamella floor. The light comes partly directly and partly at the side reflectors bundled down glare-free. Furthermore, by the prismatic glass cover emits scattered light upwards, which contributes to room lighting.
  • Lamp heads a removable, translucent plastic body have, which is designed as a push part and the prismatic glass cover and the translucent Bottom on the long sides and that facing away from the axis of rotation Front side embraces on the edge.
  • the plastic body made of a satin polymethacrylate, also called acrylic glass (Ullmann's encyclopedia of technical Chemistry, 4th edition 1980, volume 19, pages 22-26).
  • the translucent plastic body is an interchangeable one Inlay made from a colored strip of material. Through exchange of the deposited material strip are different Colorings possible and the visual effect of the Floor lamp adaptable to the interior design.
  • Floor lamp include a stand 1, one on the stand 1 cross bar 2 and two on cross bar 2 attached lamp heads 3.
  • the lamp heads 3 have two Compact fluorescent lamps 4 as an elongated light source, Side reflectors 5, a translucent bottom 6 and a top prismatic glass cover 7.
  • the lamp heads 3 are at one longitudinal end around a vertical Axis of rotation 8 pivotally connected to the cross member 2.
  • the arrangement is such that the lamp heads 3 are pivotable by 180 ° in the horizontal. This results in the examples in Figures 3 to 5 shown ways to align the Luminaire heads 3.
  • FIG. 1 A comparative view of Figures 1 and 2 one that the lamp heads 3 a removable Have translucent plastic body 9, the as Push part is formed and the prismatic glass cover 7 and the translucent bottom 6 on the long sides and the end face facing away from the axis of rotation 8 includes.
  • the plastic body 9 preferably consists of a satin polymethacrylate. At the Prismatic glass cover 7 diffused light passes through edge-side contact surfaces 10 in the plastic body 9 a. The light is in the translucent plastic body 9 directed and kicks easily on the wall-side surfaces diffuse with decreasing from top to bottom Illuminance off.
  • the plastic body 9 contains one interchangeable insert 11 from a colored Strips of material.
