Abstract

A UV discharge lamp with improved operating life features a sealed chamber (12) and two pairs of electrodes. A running electrode (13) is configured to run at a relatively high operating current, compared to a standby electrode (14) having a lower operating current. The running electrode is activated during normal operation when the lamp is required to emit a UV source for use in an industrial process. The standby electrode is activated (and the running electrode deactivated) during a standby mode in order to maintain a "ready-to-use" state. In practice the service life of the lamp is extended because each electrode pair is run closer to its optimum temperature, reducing a sputtering effect which is detrimental to operation and ultimately leads to failure.

Abstract

A UV steriliser assembly and associated method for disinfection purposes. The assembly includes a reflector (16) and a UV source, e.g. a lamp (10), configured to emit ultraviolet light at a range of wavelengths. Dependent on the assembly configuration, the reflector (16) is configured to permit or inhibit transmission therethrough of particular UV wavelengths known to assist in the photo-repair of micro-organisms. Transmission of wavelengths known to be destructive to micro-organisms can also be targeted. In this way the effectiveness of the assembly for sterilisation purposes can be optimised.
