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 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, which has an elongated emitter foundation (3), and at least one electrical connection (4), and a base containing the UV-C emitter, characterized in that the UV-C emitter is cast into the base in the area of its electrical connections by means of casting material and at least the emitter foundation of the UV-C emitter is surrounded by a flexible protective cover, 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 casting material (7) is resistant to UV-C radiation.

5. 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.

6. 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).

7. 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).

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

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

10. 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).

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

11. A UV-C emitter with an elongated emitter foundation and at least one electrical connection, characterized in that the UV-C emitter is cast into a base in the area of the at least one electrical connection by means of casting material and is surrounded by a flexible protective cover, which is radiolucent to UV-C radiation, particularly made from Teflon, at least in the area of the emitter foundation.

12. The UV-C emitter according to claim 11 characterized in that the protective cover has a thickness of 0.1 mm to 0.5 mm, preferably 0.3 mm.
