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. A device (1) for irradiating objects, comprising:

a source (6) that emits electromagnetic radiation; and

a wall (21) that consists of material that is permeable to the electromagnetic radiation and is operable as a light guide for the electromagnetic radiation, the at least one wall located between objects to be irradiated, which are accommodated in a liquid, and the source (6) that emits the electromagnetic radiation.

2. The device according to claim 1, wherein the wall (21) forms a boundary surface of a tube in which the liquid and the objects to be irradiated are accommodated.

3. The device according to claim 1, further comprising:

a housing (2), having one or more of said walls (21) located therein in the form of bodies (4), the bodies formed of material that is permeable to the electromagnetic radiation that is emitted by the source (6),

wherein said source (6) is in the form of a plurality of sources (6) of the electromagnetic radiation, and

wherein each of the bodies (4) is paired with one of the plurality of said sources (6).

4. The device according to claim 3, wherein the bodies (4) comprise strips (5).

5. The device according to claim 4, wherein each of one said plurality of sources (6) is paired with an edge of a corresponding one of the strips (5).

6. The device according to claim 3,

wherein the housing (2) is tubular, and

wherein the bodies (4) each comprise one or more strips (5) that are radially oriented relative to the housing (2).

7. The device according to claim 6, wherein the strips (5) are oriented to extend in an outward direction from a center of the housing (2).

8. The device according to claim 7, wherein additional strips (5) are provided that are oriented pointing from the inside of the housing (2) inward toward a center of the housing.

9. The device according to claim 8, wherein the strips (5) that are oriented pointing outward overlap the additional strips pointing inward.

10. The device according to claim 6, wherein the strips (5) are oriented to extend from an inside of the housing (2) inward toward a center of the housing.

11. The device according to claim 10, wherein the strips (5) that point inward overlap other strips (5) inside the housing that are oriented pointing outward from the center of the housing (2).

12. The device according to claim 3, further comprising:

projections (14) that project from an inside of the housing (2).

13. The device according to claim 12, wherein the bodies (4) comprise strips (5) that project from the inside of the housing (2) to an outside the housing (2), and are arranged so that free edges of the strips (5) are located between said projections (14).

14. The device according to claim 3,

wherein the bodies (4) have tubular areas (8), and

wherein the bodies (4) further comprise strips (5) that project from said tubular areas (8).

15. The device according to claim 3, wherein said plurality of sources (6) are arranged outside of the housing (2).

16. The device according to claim 3, wherein said plurality of sources (6) are arranged in tubular areas (8) of the bodies (4) provided inside the housing (2).

17. The device according to claim 3, wherein the bodies (4) comprise strips (5) of tubular areas (8) of the bodies (4) that project to at least one side of the bodies (4).

18. The device according to claim 3, wherein the bodies (4) comprise tubes (15).

19. The device according to claim 3, wherein said plurality of sources (6) are arranged in tubes (15) provided on an inside of a jacket of the housing (2).

20. The device according to claim 1,

wherein the wall (21) consists of one of quartz glass or silicon, and

wherein the source (6) emits one of UV radiation or IR radiation.
