<p>The invention relates to an improved sun-tanning apparatus comprising a supporting or bed surface and a plurality of low-pressure UV-A tubes arranged parallel to and at a distance from each other as radiation generators in a housing of the apparatus, the UV-A tubes being installed in a trough-like reflector and being covered on top by the supporting surface that rests on the side walls of the housing and which permits the passage of UA-V radiation. The improved apparatus provides a largely even and flat radiation outlet immediately above the supporting surface by using spacers arranged over the length and/or breadth of the apparatus between the low-pressure UA-V tubes, the supporting surface resting on the upper ends of said spacers, the lower ends of said spacers being attached in or on the base of the reflector. The spacers are a plurality of stand-off bolts that are distributed over the length and breadth of the apparatus, the supporting surface resting on the upper ends of the bolts, the lower ends of the bolts being secured in the base of the reflector. As well, it is also possible that the spacers consist of spacer profiles that extend wholly or in part over the length of the apparatus, the supporting surface resting on the upper ends of these spacer profiles, the lower ends being secured to the base of the reflector.</p> |
