<p>The present invention relates to a lamp device comprising a lamp tube (1), such as a UV intermediate pressure lamp, which is arranged in an outer globe (2) mounted in a socket (4). The end area of the outer globe (2) is enclosed by sealing means (5, 6, 7, 8, 9) for ensuring mutual vacuum-tight mounting of socket (4) and outer globe (2). It is further possible to re-use most of the elements in the lamp. Merely the worn down lamp tube must be replaced. This is particularly important when using a lamp device according to the invention in a UV system for photochemical water purification. The lamp device may additionally comprise a regulation device for regulating the intensity of electromagnetic radiation in selected wavelengths, said regulation device comprising means for temperature measurement of an inactive gas in the outer globe and means for regulating the tube voltage of the lamp.</p> |
