Definitions

  • the invention relates to a tubular screen made of an extruded metal tube with an opening running in the longitudinal direction thereof and with reflectors and / or IIalter devices inserted in the metal tube for the detachable fastening of electrical fluorescent tubes.
  • the fluorescent tube steals through the longitudinal opening on one side, wherein steels on the back of the fluorescent tube are directed through the longitudinal opening by a reflector covering the fluorescent tube.
  • the object of the invention is to improve a tubular screen of the type mentioned in such a way that the steels of the fluorescent tube are led out of the screen not only on one side but also on opposite sides with optimum bundling of steel.
  • the object is achieved with a tubular screen in that the screen is provided on two opposite sides with longitudinal openings for the steel exit, which are formed by two spaced longitudinal screen profiles, to each of which an angled reflector strip is attached on the inside , whose opposite legs each form an outwardly opening reflector.
  • Such a tubular screen designed with two longitudinal openings for the exit of the light rays of a fluorescent tube has the advantage that no additional lights directed towards the ceiling need to be attached to illuminate a room.
  • a further preferred embodiment is seen in the shape and arrangement of the reflector strips, in each of which the apex line of the opposing reflector strips runs parallel to the longitudinal axis of the fluorescent tubes.
  • the light rays are guided particularly advantageously in two opposite directions, so that light rays are optimally used.
  • the reflector strips can also be arranged offset from one another by 180 ° such that the light rays emerge asymmetrically to the longitudinal axis of the screen.
  • the fluorescent tubes are arranged offset with respect to the apex lines of the opposing reflector strips, so that the light beams emerge in a different way from the longitudinal openings of the screen.
  • the radiation intensity can thus be made variable.
  • a tubular screen 10 for receiving (holding) fluorescent tubes has two opposite longitudinal mirror-image profiles 11 which are mirror images of one another and which leave two through openings 12, 13 between them for the steels coming from the fluorescent tube 14.
  • an angled reflector strip 16 are releasably clamped on each longitudinal screen profile 11 by means of cam strips 15, the angular apex line 16a of which coincides with the imaginary longitudinal axis of the fluorescent tube 14 running parallel thereto.
  • the Leudtstoff tube 14 extends eccentrically within the tubular screen 10, so that accordingly the reflector 16 is unequal has long legs in order to optimally deflect (break) the rays coming from the fluorescent tube 14 outwards.
  • the angle which the two unequal legs of the reflector 16 form with one another is preferably over 900 .
  • the passage openings 12, 13 are expediently covered by a transparent, more or less light-diffusing cover plate 17, which also has the task of preventing the interior of the screen from becoming dusty.
  • these cover plates 17 are equipped on the edge with locking lugs 18, which are gripped behind cams 19 on the front edges of the longitudinal screen profiles 11 and are easy to release, e.g. replace the fluorescent tube or clean the reflectors.
  • the cover plates 17 consist of plastic or glass
  • two anchoring or holding shields 20 can be arranged at the end of each screen 10, which carry the capacitors 23 and other connection and / or switching devices 24 for the fluorescent tubes 14 between them on a holding plate 25.
  • narrow ribs 26 and 27 protrude into the interior of the chimney, which are integrally formed on the inside of the longitudinal screen profiles 11. Since these ribs 26, 27 preferably extend over the entire length of the longitudinal screen profiles 11, the shields 20 are accordingly contoured laterally.
  • the cam strips 15 and holding strips 22 leave a space 28 with a rounded cross-section free, so that connecting screws (not shown) can extend therein, which extend in the longitudinal direction of the screen,
  • the spaces delimited by the ribs 26, 27 can serve as cable ducts.
  • the reflector strips 16 extend symmetrically to the center plane. However, they can also be rotated through 180 ° (one relative to the other), so that the light rays emerge asymmetrically from the longitudinal openings 12, 13.
  • the ribs 26 and 27 are then to be changed in length.
  • Asymmetrical light beam exits can also be achieved by moving the fluorescent tube 14 within the screen.
  • the longitudinal profiles 11 can also be held together by other holding means, for example by screwing with end caps.
