Abstract: The subject matter of the present invention relates to an irradiation apparatus for irradiating a human body, with at least two types of tubular low-pressure lamps which emit UVA and/or UVB radiation and which are alternatingly disposed so as to lie parallel and close to one another, covering at least part of a radiation field, with the low-pressure lamps of the second type B emitting a higher UVB radiation than the low-pressure lamps of the first type A, with the diameter of the low-pressure lamps of the second type B being smaller than the diameter of the low-pressure lamps of the first type A, i.e.

Abstract: A lamp arrangement is provided having a lamp socket, a concave reflector body arranged on the lamp socket, an emitter arranged within the cavity of the reflector body and on the lamp socket, and preferably a filter disk, which covers an outlet opening of the reflector body for radiation. The reflector body is detachably connected with the lamp socket by a bayonet catch. Alternatively, the reflector body can be connected with the lamp socket by at least two gripping arms. The lamp arrangement is designed especially for use in the UV range.

Abstract: The invention relates to a rectangular frame system with one to two discoid radiation filters, as well as a tanning module with such a frame system. The rectangular frame system has an upper plate, a lower plate and two to three margin members, two margin members being opposite one another and joining the upper plate to the lower plate, the upper plate having a first opening whose perimeter describes a circle, an ellipse, a rectangle or a polygon, and the lower plate has a rectangular second opening, the second opening having a greater area than the first opening, and at least two double spring clips are arranged at the two opposite margin members, which border on side of the frame system at which no margin member is provided, such that between the lower plate and the double spring clips a first radiation filter is clamped.

Abstract: The invention relates to a tanning module with optimized guidance of the flow of cooling air, with a housing, a reflector, and at least one discoid radiation filter. The housing has the shape of a quadrilateral pyramid with a rectangular base on a first side opposite the radiation filter and a flattened pyramid apex, the rectangular base facing toward the at least one radiation filter.

Abstract: A high-capacity UV radiation apparatus, especially a high-capacity mercury low-pressure tube, for vertical applications, including a discharge chamber that is formed by a cylindrical flask made of UV-transmissive glass and that contains a filling gas, a first or a second electrode, and electrical connections leading to the outside, with an electrode holder being arranged in the area of each flask. One electrode holder is considerably longer than the other electrode holder. The temperature of the cold spot in the dead electrode space is therefore reduced on the longer electrode holder, with the steam pressure or efficiency curve of the radiation apparatus being optimized with a vertical arrangement of the radiation apparatus with the long electrode holder in the upper position. In order to ensure correct assembly, the apparatus contains a marking on at least one flask end, which provides information about the length of the respective electrode holder.

Abstract: To increase the radiation output from a discharge lamp having a diaphragm arrangement located between an anode (3) and a heatable cathode (4), the diaphragm arrangement constricts the radiation discharge path along an axis (5, 105) extending through the diaphragm opening and towards the anode (3, 103), and has a dimension along the length of said axis of at least 0.3 mm. The diaphragm arrangement can be formed by a plurality, preferably about 3 diaphragm elements (6, 7, 8), each having diaphragm openings of from between 0.1 to 2 mm, made of sheet metal of a thickness of at least 0.03 mm, and preferably of between 0.1 to 1 mm, and in which the spacing of the diaphragm openings (10, 11, 12) with respect to each other is in the range of about 0.1 to 5 mm, preferably about 0.3 mm; alternatively, the diaphragm arrangement may include one massive diaphragm having an axial thickness of between 1 and 50 mm, preferably between about 1 and 5 mm, and spaced from the anode by between about 0.

Abstract: A low-pressure discharge lamp, in particular a deuterium lamp, including a cylindrically symmetric partition unit which forms two hollow spaces at each of the sides of the discharge lamp. Both hollow spaces are connected through an opening in the partition unit, which confines the plasma generated by a high-frequency electromagnetic field to pass through the opening to increase the intensity of the emitted radiation. Both sides of the cylindrically symmetric partition unit are provided with a hermetic seal, at least one of which sides is a radiation emission window. The generation of the electromagnetic field takes place capacitatively through electrodes located on the sides of the discharge lamp. At least one of the electrodes is disposed on the radiation emission exit window and has an opening for the radiation to exit.

Abstract: A low-pressure discharge lamp, in particular a deuterium lamp, includes a lamp envelope in which a plasma for generating UV radiation is formed by the capacitative generation of a high-frequency electromagnetic field. At least two partitions having openings are provided, wherein the openings are disposed on a common optical axis. The openings serve to constrict the plasma contained within the discharge vessel, which provides a high radial intensity of the plasma with high radiation stability for directing radiation along the optical axis. The radiation exits through a radiation emission window which is pervious to UV rays or through two exit windows placed opposite each other along the optical axis. The discharge lamp is particularly suitable for analytic measuring tasks, for example, as a light source in spectrophotometers.

Abstract: An electrodeless low pressure discharge lamp, preferably filled with deuterium gas, is provided with a cylindrical envelope made from quartz glass and surrounded by a cylindrical excitation coil driven at between 10 and 800 MHz. Within the lamp envelope, there is provided a cylindrical aperture member made from boron nitride which in a radial direction extends to the inner surface of the envelope and which is provided with an uninterrupted coaxial channel for confining to a small diameter the plasma discharge arc generated during operation of the lamp, the aperture member having an optical axis extending through coaxially with its channel, the radiation emitting in a directed pattern along the optical axis.
