Abstract: The invention relates to an irradiation unit for the UV irradiation of particularly web-shaped substrates, comprising a housing (10), a tubular UV lamp (12), arranged therein and a reflector arrangement (14), running along the UV lamp (12). According to the invention, a simple exchangeability may be achieved, whereby the reflector arrangement comprises a support profile (22), retained in the housing (10) and a reflector profile (24), embodied as a shape-retaining molded piece which may be detachably connected thereto.

Abstract: The invention relates to a UV irradiation unit comprising a housing (10), a rod-shaped lamp (12) which is arranged therein, a reflector (14) which extends along the UV-lamp (12) and which defines a lamp chamber (22) which surrounds the UV-lamp (12), in addition to a channel system (20) for guiding a cooling coolant through the reflector (14). According to the invention, the channel system (20) is arranged on the outside of the lamp chamber (22) such that it remains void of the coolant flow (24) for operating the lamp in an optimum manner.

Abstract: The invention relates to an irradiating device, especially for irradiating with ultraviolet light substrates which are provided with a coating that can be cured using ultraviolet light. The inventive device comprises a longitudinally extending radiation source (12) which is provided for emitting ultraviolet and/or visible electromagnetic radiation, which is arranged in a housing (10) between a reflector (18) and a housing opening (14) that can be aligned with an object (16) to be irradiated, and which is preferably configured as a tubular mercury discharge lamp. The inventive device also comprises a cooling system (20) for dissipating the waste heat generated by the radiation source (12). The aim of the invention is to create a compact modular construction and, optionally, an oxygen-reduced illumination zone.

Abstract: The invention relates to a method and to a probe arrangement for the electromagnetic detection of metal objects. For this purpose several receiving loops are provided, which detect a secondary signal emitted by the sought object. The secondary signals received with the different loops are interconnected and evaluated in object-specific manner. This gives precise information on the position and location of the object to be detected.
