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.

Rectangular frame system with one to two windowpane-like radiation filters and a tanning module

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.

Tanning module with a housing

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.
