Abstract

A device (1) for irradiating titanium-dioxide-coated fibers with UV radiation includes a housing (2) that is filled with water. Bodies (4), including strips (5), which consist of quartz glass, are arranged in the housing (2). LEDs (7), which emit UV radiation, are paired with at least one of the longitudinal edges of the strips (5). UV radiation is uniformly emitted to the fibers by the strips (5), so that these fibers acquire anti-fouling properties.

Claims

1. Device (1) for irradiating objects, in particular fibers coated with titanium dioxide, comprising at least one source (6) for the emission of electromagnetic radiation, wherein at least one wall (21) that consists of material that is permeable to the electromagnetic radiation and that acts as a fiber optic light guide is provided between the objects that are accommodated in a liquid, such as water, and the source (6) for the emission of electromagnetic radiation.

2. Device according to claim 1, wherein the wall (21) is the wall (21) of a tube (20), in which a liquid, such as water, and the objects that are to be treated are accommodated.

3. Device according to claim 1, wherein the device comprises a housing (2), wherein at least one wall in the form of bodies (4) that consists of material that is permeable to the electromagnetic radiation that is emitted by the sources (6) is provided in the housing (2), and wherein sources (6) for the electromagnetic radiation are paired with the bodies (4).

4. Device according to claim 3, wherein the bodies (4) comprise strips (5) and/or tubes (15).

5. Device according to claim 1, wherein the wall (21) or the body (4) consists of quartz glass or silicon, and the sources (6) emit UV radiation or IR radiation.

6. Device according to claim 3, wherein the housing (2) is tubular and wherein strips (5) are radially oriented relative to the housing (2).

7. Device according to claim 6, wherein strips (5) that are oriented pointing outward from the center of the housing (2) are provided.

8. Device according to claim 6, wherein strips (5) that are oriented pointing from the inside of the housing (2) to its center are provided.

9. Device according to claim 8, wherein the strips (5) that point inward and outward overlap one another.

10. Device according to claim 3, wherein projections (14) project from the inside of the housing (2).

11. Device according to claim 10, wherein strips (5) that project from the inside to the outside are arranged with their free edges between projections (14).

12. Device according to claim 3, wherein the bodies (4) have tubular areas (8) and wherein strips (5) that project from tubular areas (8) are provided.

13. Device according to claim 4, wherein sources (6) for electromagnetic radiation are paired with edges of the strips (5).

14. Device according to claim 3, wherein sources (6) for electromagnetic radiation are arranged outside of the housing (2).

15. Device according to claim 3, wherein sources (6) for electromagnetic radiation are arranged in tubes (15) or tubular areas (8) of bodies (4) provided inside the housing (2).

16. Device according to claim 3, wherein strips (5) of tubular areas (8) of the bodies (4) that project to at least one side are provided.

17. Device according to claim 7, wherein strips (5) that are oriented pointing from the inside of the housing (2) to its center are provided.

18. Device according to claim 17, wherein the strips (5) that point inward and outward overlap one another.
