Abstract

The invention relates to a UV-C sterilizing lamp for the treatment of a medium with UV-C radiation in order to kill the microorganisms contained therein by means of at least one UV-C emitter (2). The emitter has an elongated emitter foundation (3) and at least one electrical connection (4), and a base (5) holding the UV-C emitter (2). The at least the emitter foundation (3) of the UV-C emitter (2) is surrounded by a flexible protective cover (6), which is radiolucent to UV-C radiation. The invention furthermore relates to a sterilizing system with at least one UV-C sterilizing lamp of the invention.

Claims

1. UV-C sterilizing lamp (1) for the treatment of a medium with UV-C radiation, in order to kill the microorganisms contained therein, with at least one UV-C emitter (2), which has an elongated emitter foundation (3), and at least one electrical connection (4), and a base (5) containing the UV-C emitter (2), characterized in that at least the emitter foundation (3) of the UV-C emitter (2) is surrounded by a flexible protective cover (6), which is radiolucent to UV-C radiation.

2. The UV-C sterilizing lamp (1) according to claim 1, characterized in that the protective cover (6) is made of Teflon.

3. The UV-C sterilizing lamp (1) according to claim 1, characterized in that the protective cover has a thickness of 0.1 mm to 0.5 mm, preferably of 0.3 mm.

4. The UV-C sterilizing lamp (1) according to claim 1, characterized in that the UV-C emitter (2) is cast into the base (5) in the area of its electrical connections (4) by means of casting material (7).

5. The UV-C sterilizing lamp (1) according to claim 4, characterized in that the casting material (7) is resistant to UV-C radiation.

6. The UV-C sterilizing lamp (1) according to one of the preceding claims characterized in that the base (5) is formed from a ceramics body, which is especially filled with glass wool as filling material.

7. UV-C sterilizing lamp (1) according to claim 1 characterized in that the UV-C emitter (2) is secured against involuntary removal or falling out of the base (5) by means of a clamp arranged in the base (5).

8. The UV-C sterilizing lamp (1) according to claim 1 characterized in that an operating technology for the UV-C emitter (2) is arranged separately outside of the UV-C sterilizing lamp (1).

9. The UV-C sterilizing lamp (1) according to claim 1 characterized in that the UV-C emitter (2) is a compact emitter.

10. The UV-C sterilizing lamp (1) according to claim 1 characterized in that the UV-C emitter (2) is a high output emitter.

11. The UV-C sterilizing lamp (1) according to claim 1 characterized in that the UV-C emitter (1) is a high output UV-C compact low pressure emitter with two discharge tubes (3a, 3b).

14. A sterilizing facility with at least one UV-C sterilizing lamp (1) according to claim 1.

12. A UV-C emitter (2) with an elongated emitter foundation (3) and at least one electrical connection (4), characterized in that it is surrounded by a flexible protective cover (6), which is radiolucent to UV-C radiation, particularly made from Teflon, at least in the area of the emitter foundation (3).

13. The UV-C sterilizing lamp (1) according to claim 12 characterized in that the protective cover has a thickness of 0.1 mm to 0.5 mm, preferably 0.3 mm.
