Definitions

  • All tanning devices whether for home use or for professional use, are equipped with UV radiation sources.
  • these high-pressure units usually consist of a reflector, a high-pressure mercury lamp in a corresponding socket and a filter in front of it.
  • These subsystems are usually summarized in one housing.
  • An additional fan ensures that the heater is not overheated.
  • the usual reflector is a light box made of aluminum, in which the discharge arc of the spotlight is arranged parallel to the parabolic reflector plate.
  • the point of intersection of the plasma path lies in the focal point of the cutting line of the reflector plate.
  • the correct adjustment to the focal point is usually not achieved.
  • the reflectivity of the aluminum material used is usually less than 80%. This value is reduced again by using a hammer impact surface.
  • the design of the reflector as a light box is also not optimal, since the optical geometry only applies to one level. This results in further losses.
  • a badly designed reflector leads to losses on the irradiation surface of up to 70%. This means that then only 30% of the beam flow of a high-pressure lamp is effective on the surface to be irradiated.
  • the glass used serves as the sole filter, the opening flank of which differs greatly in the UVB, which means that there is no uniform UVB radiation. Furthermore, neither the IR nor the visible light is blocked, which means that use remains very problematic.
  • the glass thickness remains below 1 mm, which also means that the filter function is limited to the unusable one.
  • the device according to the invention of a simple UV filter lamp represents the solution to the problem.
  • a glass bulb which preferably consists of two parts, surrounds a tanning lamp that is built on a stand. Since the lower part of the glass bulb is designed as a paraboloid and is provided with an aluminum coating and the center of the plasma path of the emitter is at the focal point of the paraboloid, the reflection behavior of this combination is excellent. For this reason, namely the high effectiveness of the radiator-reflector combination, the power of the radiator can remain lower than in conventional systems.
  • the evacuation of the lamp eliminates the need for a fan. However, if a very high output is required, the lamp can also be set up for forced cooling. Because of the symmetrical structure of the lamp, the air flow of the cooling can be precisely determined, with which the performance data are retained.
  • the filter system is an essential part of the lamp. Either the entire glass bulb or preferably only the upper part of the UV filter lamp are made of a special glass, which is characterized in that it is largely blocked for visible and near IR light, whereas UVA has a high transmission.
  • the opening flank of the filter glass for short-wave UV is set up in such a way that the 313 nm line of mercury vapor can come into effect, the transmission here, depending on the area of use, being between 10 and 35%. A higher transmission must be ruled out, since otherwise the aggressive 303 nm line will also take effect, with which the radiation can cause more DNA damage than the natural sun.
  • the glass parts are shaped in such a way that the direct radiation from the mercury high-pressure lamp does not strike the silicone rubber in order to avoid its embrittlement by high-energy UVC radiation. If the silicone rubber remains elastic, the different expansions of the glass parts can be absorbed without causing a leak, with which the lamp vacuum would be lost.
  • the paraboloid of revolution is made of metal, optimally made of aluminum, the inside being made of anodized aluminum in order to ensure the highest possible reflectivity for UV.
  • This metal mold runs down into a tube in which the radiator is inserted. At the top, a collar ensures that the Fil tersusion can be fitted.
  • Both the filter disk and the radiator should be connected to the housing via a seal, so that it is ensured that the housing can be sealed airtight. Both the inserted radiator and the filter disk are pressed onto the seals with spring pressure.
  • the air in the housing expands due to the heating of the radiator and the air can leave the housing past the radiator seat as well as past the filter disk. If the heater is switched off, the indoor air cools down and a negative pressure is created. Since both the filter disc and the radiator are pressed against the seals, no air can flow in from the outside. If ozone is generated, it is now trapped in the housing and cannot escape to the outside. Also When it is operated again, the internal air only heats up to the previous pressure, so that there is no longer any excess pressure in the interior, which means that no more air escapes to the outside. This keeps the ozone inside the case.
  • the seals preferably consist of polysiloxane filled with titanium oxide. The filling is necessary to prevent high-energy UV radiation from entering the sealing ring. Clear polysiloxanes absorb the UV light, which leads to the dissolution and embrittlement of the plastic.
  • Another advantage of this construction is the possibility of exchanging both the emitters and the filter disks.
  • the emitters are preferably those with auxiliary electrode ignition. This is particularly indicated in the case of a metallic housing, since arcing can occur here at high voltage surges.
  • the filter disk is preferably a diffusion disk which also acts as a filter at the same time.
  • Figure 1 shows the UV filter lamp and Figure 2 a solution for the glue point.
  • Figure 2 shows the following details. The following details are shown in the figures:
  • the resistors 6 lead to the auxiliary electrodes 5 of the Hg high-pressure burner.
  • the further wire feeds open onto the main electrodes 4, between which the plasma path 3 is formed when the operating voltage is applied.
  • the lower glass bulb 7, which is designed as a paraboloid, is provided with a reflection layer 8, which is optimally designed for the reflection of UV radiation. It is also possible to design this reflection layer only for UV, with which the heat radiation can pass through the bulb 7 to the outside.
  • the filter part 9 is placed on this glass bulb lower part 7 and seals the lower part 7 airtight via the adhesive point 10.
  • the filter disk 9 rests on the lower part of the glass bulb 7.
  • the reflective layer 8 protects the polysiloxane 11, which connects the glass parts to one another in a gas-tight manner.
  • Expansion of the filter region 9 is compensated for by the elasticity of the silicone rubber 11 compared to the less expanding glass lower part 7.
  • the filter disc 13 On the housing made of metal 12 lies the filter disc 13, which is held in the collar 14 of the housing.
  • the seals 15 ensure the airtight seal.
  • the base 17 of the radiator 16 is seated in the connecting tube piece 18 of the housing 12.
  • the sealing rings 20 ensure the airtight seal on the tube protuberance 19.
  • the power is supplied via the connector 21.
  • both the filter disk 13 is pressed onto the seals 15 in the collar 14 and also the base 17 onto the seals 20 on the raw protuberance 19.
