Definitions

  • the present invention relates to a set comprising a laminar flow unit and illuminating equipment to produce illuminated zones of extremely clean atmosphere.
  • Contamination of working places by foreign particles and germs from the surrounding atmosphere can be excluded with the aid of modern clean air techniques according to the laminar flow principle with a safety that is several decimal powers higher than that of methods hitherto used, provided, however, that on the respec-- tive working places laminar flow currents of air of high I quality are maintained.
  • the set according to the invention comprises a laminar flow unit and illuminating equipment to produce illuminated zonesof extremely'clean. atmosphere,
  • the illuminating equipment consists of a source of light and a deviating system for the light, the source of light being installed outside and the light deviating system inside of thezone of "extremely clean atmo-
  • the deviating system consistsof atleast one mirror or prism or light-conducting cable. Deviating systems consisting of small mirror strips or a plurality of narrow prisms are preferred so that no shadow'with respect to flow technics is formed at the place of operation.
  • FIGS. 1 and 2 illustrate the state of air of laminar flow units in vertical and horizontal arrangement.
  • FIGS. 3-5 illustrate respective embodiments of the present invention.
  • air is introduced into the laminar flow unit consisting of enclosure 1, in which are installed fans (not shown) and highefficiency filters 6, with lateral limitations or curtain walls confining the flow of air to a predetermined area.
  • High-efiiciency filters 6 purify the air and produce a parallel flow of air 2 in the sense of laminar flow technics.
  • one lateral limitation or'wall l1 of the laminar flow unit has an opening 10 through which the light of reflector 8, which is outside of the laminar flow unit, enters the theless almo'st'fthe entire'light reaches the working place. The same applies to the use of prisms.
  • the reflector 8' is within the laminar flow unit.
  • the reflector causes the formation of air whirls and, owing to the upcurrent due to hotair, uncontrolled back and transverse cu rrents-4 areformed.
  • the uncontrolled flow prevents the supply of extremely clean air, the elirn ination of contaminations set free by the working process, or operation and promotes the transport of impurities to the working-place or patient 3.
  • metal 5 indicates the working personnel from which air should possibly not be directed to the working place 3.
  • a device for illuminating and providing clean air' to a clean room cornprising, in combination, means for producing laminar air flow of clean air in at least a pre determined portion of said room and means for producing an illuminated zone in the clean air laminar flow in the room, said means for producing an illuminated zone comprisinga source of light located outside of the laminar air flow in said predetermined portion of the room for directing light thereto and means positioned in the path of said laminar air flow and in said predeterminedportion of the room,'for deviating light from said light source to a predetermined location within said laminar air flow while substantiallymaintaining said laminar air flow to said predetermined portion of said room.
