Definitions

• the invention relates to a treatment light emitting polarized light for biostimulation with polarized light.
• the invention relates to a treatment light which emits polarized light with a certain intensity and wavelength, and thereby covers a certain area.
• FIG. 5 of this reference shows a treatment lamp in which a polarization filter is used.
• the lamp is suitable for generating a light bundle with a diameter of approximately 55 mm and the lamp output is 150 W.
• the treatment lamp generates a lot of heat and is cooled by a fan. A lot of power is lost in the form of heat and the efficiency is relatively low, which also causes serious cooling problems.
• the manageability of this lamp is not optimized while at the same time realizing optimal cooling and optimum efficiency.
• the use of the Brewster polarizer with the mirror sandwich made of float glass panes lying directly on top of one another achieves a high polarizer efficiency while, on the other hand, the mirror sandwich made of float glass panes is easy to cool is realized because, for example, there are no insulating air gaps between the individual glass panes.
• the fact that the float glass panes lie directly on top of one another prevents the polarizer from becoming contaminated by the penetration of dust particles between the float glass panes. This means that the lamp has a longer service life.
• the light filter plate closes off the second hollow cylinder.
• the second hollow cylinder is closed translucently, but at the same time mechanically sealed against the ingress of dust.
• the reflector closes the first hollow cylinder by means of a seal, as a result of which the entire tube device consisting of the first and the second hollow cylinder is hermetically sealed and is thus protected from contamination.
• Light source arrangement arranged in the middle and front part such that the space around the light source arrangement in the vicinity of the polarizer is larger than in the vicinity of the reflector. This results in an optimal cooling air flow.
• the first angle is between 105 ° and 120 °.
• the handle is provided on its outer surface with indentations for receiving the fingers on its side facing away from the light exit opening of the front part. This allows the treatment light to be held optimally and directed towards the area to be treated, for example the face of the user.
• the float glass panes have elliptical shapes and the glass support has the shape of an elliptical receiving trough with an elliptical bottom and a wall running around a substantial partial area of the bottom, the wall being provided with a plurality of locking lugs which enter into the mirror sandwich intervene and hold it in this way. Furthermore, the mirror sandwich can rest directly on the cut surface of the tube device, which ensures a further hold.
• the lamp is advantageously a metal-halogen lamp assembled with the reflector and is underheated by at least 5% during operation. This results in a longer lamp life.
• the lamp is particularly advantageously designed in such a way that it emits no or only a negligible proportion of ultraviolet light.

• Figure 9 is a section indicated by section line A-A in Figure 7;
• Figure 10 is an enlarged view of the in Figure 9 as Detail called "Detail 1".
• the treatment lamp 1 shown in Figure 1 consists of three construction parts, i.e. a housing 2, a light source arrangement 3 and a fan 4.
• the housing 4 itself consists of a handle 21, a curved central part 22 and a front part 23, the shape of which can be clearly seen from FIGS. 1 to 4.
• the housing 2 is preferably made of two plastic parts which are matched to one another and which determine the cavity for accommodating the other structural parts.
• the light source arrangement 3 is arranged centrally in the middle part 22 and the front part 23 of the housing 2 in the position shown in FIG. 1 in such a way that a distance is formed essentially everywhere between the inner housing wall and the light source arrangement.
• the term "centric" means that this distance in the direction perpendicular to the plane of Figure 1 is the same on both sides.
• the light source arrangement 3 is not arranged completely centrally in the drawing plane.
• the light source arrangement 3 consists of two cylindrical tubes 31, 31 welded to one another at an obtuse angle, the axes of which are at an angle of approximately 114 °, which corresponds to twice the Brewster angle.
• the two tubes 31, 32 are cut at the outer apex along a plane in which the intersection of the tube axis lies, and the resulting elliptical opening is covered by a Brewster polarizer 33.
• the light source arrangement 3 can be seen in FIG. 5 in a perspective view.
• FIG. 6 shows part of the Brewster polarizer 33 in a sectional view.
• the Brewster polarizer 33 consists of a number (for example 5) of thin, plane-parallel, elliptical float glass panes 34 arranged one behind the other, which lie directly on one another, that is to say without forming a distance between them.
• the float glass panes 34 are enclosed in a glass carrier 35, which is shown in FIG. 6 only purely schematically.
• the float glass panes 34 achieve a high polarizer efficiency while, on the other hand, the mirror sandwich made of float glass panes is easy to cool because these lie directly on top of one another and are not separated from one another by insulating air gaps between the glass panes.
• the float glass panes are therefore in heat-conducting contact with one another, so that the mirror sandwich can be regarded as a one-piece component with regard to the heat-conducting properties.
• the fact that the float glass panes lie directly on top of one another means that dust particles cannot get between the glass panes.
• the Brewster polarizer maintains its high efficiency even after a long service life.
• the glass carrier 35 has the shape of an elliptical receiving trough with an elliptical bottom 39 and a wall 40 running around a substantial partial area of the bottom 39.
• the wall 40 is provided with a plurality of locking lugs 41, which laterally into the in the
• FIG. 7 to 10 intervene mirror sandwich, not shown.
• the wall 40 does not have to extend around the entire elliptical base 39, so that, for example, an assembly of the mirror sandwich with the glass carrier 35 close to the tubes 31, 32 is possible without the glass carrier 35 abutting the housing 2.
• the float glass panes therefore lie directly on the cut edge surface of the tube device made of tubes 31 and 32, which are cut at a Brewster angle.
• the float glass panes 34 or the glass carrier 35 are sealed by means of a seal to the cut surface, as are a reflector 36 and a light filter plate 37 to the tubes 31 and 32, as will be explained further below. This will make the interior of the tubes 31 and 32 formed tube device mechanically sealed so that no dust can enter this interior.
• a lamp 42 preferably a metal-halogen lamp, with a reflector 36 which is held tightly pressed against an annular inner axial shoulder of the tube 31, preferably between the annular inner axial shoulder and the reflector 36 a seal, not shown, is arranged.
• the lamp 42 radiates visible and infrared light axially forward, the angle of incidence on the Brewster polarizer 33 being 57 °.
• the lamp 42 is designed in such a way that it emits virtually no ultraviolet light, which must be avoided with regard to the risk of burns for the user and the undesired, selective tanning.
• the lamp power is about 20 W, but must not be more than 80 to 100 W, since the cooling conditions are essentially optimal below this limit power.
• the float glass panes 34 of the Brewster polarizer 33 reflect the light parallel to the axis of the tube 32, the reflected light being linearly polarized.
• the non-reflected light components hit the black inner surface of the closure plate 35 and the heat generated is dissipated by the cooling air.
• the interior of the light source arrangement 3 is closed at the front end of the tube 32 with a yellow light filter plate 37.
• the purpose of the light filter plate 37 is, on the one hand, to filter out spectral components below approximately 400 to 450 n from the light beams reflected at the polarizer 33 and, on the other hand, as already indicated above, to mechanically close the interior of the light source arrangement 3, so that the optical properties of those arranged here Elements are not affected by dust formation.
• Mounting plate 38 is arranged, which is held by a plurality of support elements of the housing 2, not shown in the drawing.
• the electrical connection line leads to the mounting plate 38, which also carries a fuse and some electrical components.
• an electrical attenuator is connected in series with the lamp 42, so that the lamp 42 is underheated to about 2 to 5%.
• Overheating the lamp 42 on the one hand increases its lifespan and on the other hand shifts the spectral distribution of the emitted light in the direction of the infrared region (by reducing the effective light temperature), which increases the depth of penetration of the rays. It is also possible that such a spectral distribution is more favorable for biostimulation.
• the decrease in light temperature also reduces the
• the underheating of the lamp 42 can also be achieved by reducing the supply voltage. If the nominal voltage of the lamp e.g. Is 12 V, the transformer that feeds the lamp can be designed to deliver around 11 - 11.4 V.
• the fan 4 is oriented axially in the handle 21 axially opposite to the lamp 42 and sucks the air into the housing interior through the inlet opening 24 (FIG. 3) formed around the light source arrangement 3 into the housing.
• the outflow takes place via slots 25 (FIGS. 1 and 4) at the free end of the handle 21.
• the cooling air flows in the housing interior along the entire lateral surface of the light source arrangement 3. This flow is illustrated by arrows in FIG.
• the shape of the housing shown in the drawing is not only aesthetically pleasing, but it also leads to very cheap cooling. Behind the closure plate 33 and in the region of the upper end of the tube 31 is the volume of the
• the heat from the large surface of the closure plate 33rd dissipate; the interior space in the area of the lamp 35 then decreases, as a result of which the air speed is significantly increased.
• the air flows quickly over the parabolic surface of the reflector 36 with the lamp 42, as a result of which intensive cooling takes place here and the operating temperature of the lamp 42 does not exceed the permitted values.
• the temperature of the housing does not become more than 20 ° C higher than the ambient temperature even after the lamp has been in operation for a long time.
• the axis of the handle 21 is a little oblique to the lamp axis and in such a way that the direction of the light rays emerging from the treatment lamp 1 emerge at an angle between 105 to 120 °, preferably 105 to 110 ° to the handle axis. This orientation enables a very pleasant posture and a comfortable light treatment.
• the inner diameter of the tubes 31, 32 is also chosen to be 50 mm.
• the treatment lamp emits parallel, polarized light in a circular bundle with a diameter of 50 mm and the light power density is approximately 50 mW / cm 2 .
