  • the invention relates to a modular light protection system for protection against UV light when cleaning a medium, such as an air or liquid flow, consisting of a first chamber wall and at least one second chamber wall, which together partially delimit a plurality of flow paths for a medium, wherein the first chamber wall has a plurality of inlet openings for the medium, wherein the respective inlet opening has an opening axis and spans a first opening plane which is aligned at right angles to the opening axis, and wherein the second chamber wall has a plurality of outlet openings for the medium, wherein the respective outlet opening has an opening axis and spans a second opening plane which is aligned at right angles to the opening axis, and wherein the respective chamber wall has a wall zone between the openings which is designed to be closed.

  • a modular light protection system is already known from DE 10 2020 204 403 A. This has a light protection chamber made up of three components: an outer chamber with an inlet nozzle and a chamber nozzle, an outer wall with an outlet nozzle and a cup-shaped inner chamber that sits on the chamber nozzle.
  • the invention is based on the object of designing and arranging a modular light protection system in such a way that simple production is ensured despite optimal light protection.
  • the respective wall zone is at least partially concave and has several depressions, whereby the respective depression of a chamber wall protrudes relative to an adjacent opening plane of this chamber wall by a dimension t in the direction of the opening axis.
  • the respective depression is thus limited at the bottom by the adjacent opening plane. This ensures that there is sufficient space for a UV source within the depression.
  • the construction height of the light Protection system consisting of two chamber walls can thus be kept to a minimum.
  • the task is also solved by an assembly consisting of a modular light protection system with a UV source within at least one trough or by an air purification system with such an assembly.
  • first chamber wall and the second chamber wall are positioned relative to one another in such a way that the respective trough of one chamber wall is positioned in front of the respective opening of the other chamber wall. If an opening axis of the inlet opening is aligned coaxially to an axis of symmetry of the trough, optimal protection or shielding effect of the light protection system is achieved.

  • the respective opening is designed as a recess and the respective trough as a molding.
  • first chamber wall and the second chamber wall have the same shape. This brings further cost savings. A second tool is not necessary.
  • the shape of the chamber wall is largely determined by the architecture of the troughs together with the offset openings.
  • the respective opening axis together with the orientation of the collar, essentially determines the main direction of the inlet flow or the main direction of the outlet flow.
