Definitions

  • the invention relates to a device for emitting light and similar radiation such as UV radiation, with a radiation generator and a concave, one-dimensionally curved reflector.
  • a radiation generator in the form of a rod-shaped fluorescent lamp is arranged in a trough-shaped reflector, which ensures that parts of the radiation emerging from the rear of the lamp are also used.
  • the radiation source is visible to the viewer's eye. This leads to glare problems, the greater the higher the radiation intensity of the radiation generator and which can also be solved with the aid of upstream anti-glare grids, anti-glare glass panes and the like. Only partially remedy the like.
  • the invention has for its object to provide a device of the type described in the introduction, with which glare and similar problems can be reduced considerably.
  • the reflector has at least in the majority of its cross section the shape of a spiral and the Radiation generator encloses by more than 360 °, the inner end section of the reflector being at a distance from the zero axis and the outer end section overlapping the inner end section to such an extent that only reflected radiation emerges from the reflector.
  • the radiation generator is completely enclosed by the reflector and can therefore no longer be seen from the outside. Nevertheless, because of the spiral shape of the reflector, the entire radiation of the radiation generator after one or more reflections is directed outwards through the outlet opening which is formed between the outer end section and the rest of the reflector.
  • the luminance which is already smaller in the inner end section than on the surface of the radiation generator, continues to decrease with increasing radius of the spiral, so that the reflector surface visible through the outlet opening has a considerably reduced luminance. As a rule, the viewer can therefore look into the outlet opening without being blinded.
  • the spiral preferably has a constant angle of inclination with respect to radial lines starting from the zero axis, and is therefore an Archimedean spiral. This results in a high uniformity of the radiation intensity in the illuminated field.
  • the angle of inclination should not exceed 79 °. It is then ensured that the envelope curve of the once reflected rays runs radially outside the inner end section and that some of the rays are not returned to the inner part of the reflector.
  • the angle of inclination should be at least 70 ° so that the reflector does not become too large.
  • the angle of inclination is approximately 77.5 °.
  • the angle of overlap between the inner and outer end section depends on the particular circumstances. It is advantageously 30 ° to 60 °. On the one hand, this allows adequate coverage of the radiation generator, but on the other hand keeps the number of reflections required small. ; i
  • Luminaires are usually arranged with the beam exit opening facing downwards. It is known that an observer's eye is not dazzled when the horizontal component of the emerging rays is small. Therefore, should the output-side luminance be too high due to the use of very strong radiation generators; can be assigned to the outlet opening in a known manner anti-glare slats and / or an anti-glare glass pane, for example made of prism glass. A further possibility is that the overlap angle is selected to be large between inner and outer end portion, that the emerging radiation is emitted in an angular range of a maximum of 110 0, preferably 90 ° or less.
  • the outer end section ends in a flat piece tangentially adjoining the spiral, which is preferably flat.
  • the rays reflected here are directed so that they scatter less strongly and there is a concentration of the beam.
  • Reflective side walls are advantageously provided on the end faces of the reflector. In this way, rays that have a large component in the direction of the zero axis are also used, since they re; be inflected.
  • the reflecting side walls have an inclination with respect to the cross-sectional plane of the reflector.
  • the rays reflected here have a reinforced component in the cross-sectional plane, so that they scatter less when they exit.
  • the side walls have flat surfaces. But they can also be formed by spherical sections.
  • the reflector can be of a spherical housing be enclosed, which forms the reflective side walls.
  • the spiral reflector Due to the presence of the spiral reflector, essentially point-shaped radiation sources can even be used. These include numerous high-pressure burners and, above all, short-arc lamps. Such radiation sources make it possible to generate an extraordinarily high luminous flux with a comparatively low output. However, the total radiation power is generated in a relatively small area with an extremely high radiation density.
  • the spiral reflector both reduces the density of the emerging radiation to an acceptable level and distributes the radiation over a rectangular exit opening.
  • a high-pressure burner in the form of a metal halide burner is particularly recommended, since it generates radiation in the entire visible range, which results in high authenticity in the color rendering, and can also be designed so that it can emit UVA radiation.
  • a tin halide short arc lamp with tin-doped sodium vapor is recommended. This also achieves an even spectral radiation distribution with an almost sun-like spectrum.
  • the radiation generator can have at least two radiation sources with different spectral distributions offset with respect to one another in the direction of the zero axis.
  • the property of the reflector to distribute radiation in the direction of the zero axis is used to mix the radiation of at least two radiation sources. In this way, a spectral distribution can be achieved that would not be possible with a radiation source alone.
  • the radiation sources can include a high pressure burner and an incandescent lamp.
  • the two radiation sources complement each other because the blue spectral range is more pronounced in the high-pressure burner and the yellow-red spectral range is more pronounced in the incandescent lamp.
  • the radiation sources comprise two identical short-arc lamps, which have a blue-b etontes and a rotshowes spectrum caused by different doping of the vapor.
  • it can be prepared by different doping of sodium vapor with tin to change the color temperature of about 5200 ° K to 3000 ° K, thereby ere shift the long-wave spectrum into l ig.
  • the use of two radiation sources is also interesting if a lamp with start-up behavior and an incandescent lamp are used.
  • the light bulb gives sufficient light immediately after switching on. After the start-up time, e.g. 1 to 4 minutes, then the complete spectrum and the total radiation power are available; addition.
  • a rod-shaped fluorescent lamp is used as the radiation generator, its axis should run approximately along the zero axis.
  • much stronger fluorescent lamps than usual can be used, for example a three-band fluorescent lamp emitting sun-like light.
  • the radiation generator emits UVA radiation with particular advantage and a filter which essentially filters out UVB and UVC radiation is provided.
  • This can be formed by the glass envelope of the radiation source or can also be provided.
  • additional UVA radiation generated to visible light there is an even more accurate replica of natural sunlight, which causes corresponding biochemical and endocrine reactions (e.g. improves vision, reactivates rhodopsin, controls nerve tone, activates glandular activity and stimulates skin metabolism), but with harmful effects ( Sunburn, keratitis, conjunctivitis) can be avoided.
  • pronounced radiation is generated in the UVA range, there is a cosmetic radiation device for quick tanning or a medical radiation device for the treatment of skin diseases, such as psoriasis.
  • the user can be placed near the outlet opening, where there is a high UVA radiation intensity, because heat radiation is absorbed to a great extent by the reflector.
  • the outlet opening can point downward and the reflector can be connected to a device for lowering up to a bed.
  • the radiation generator has a continuous spectrum between 320 nm and 760 nm. This corresponds to the optimal replica of natural sunlight. It does not matter whether only one radiation source is used or whether two or more radiation sources are involved.
  • Agents for changing the spectral composition of the radiation emitted are of particular value. In this way, the radiation can not only be adapted to individual needs. Rather, the spectrum and possibly also the illuminance can be changed according to the daily rhythm.
  • a support which carries a holder for a radiation source, is detachably connected to the reflector and covers an opening, the cross section of which is larger than that of the holder or the radiation source. This enables the radiation source to be installed and removed in a simple manner, but nevertheless to keep the interior of the reflector closed.
  • the carrier can form an end wall.
  • the opening is provided in the middle of the spiral surface of the reflector.
  • it can be designed as a reflector on the inside.
  • a part of the reflector which is adjacent to the radiation generator is designed as a flap which can be pivoted with respect to the rest of the reflector or is removably attached to the rest of the reflector.
  • a particularly economical embodiment has a spiral sheet metal housing, the inner surface of which forms the reflector.
  • the reflector and housing are therefore identical.
  • the structural dimensions are small.
  • the reflector is surrounded by a cuboid-shaped housing which tightly surrounds the reflector and in one of its largest area is the beam exit opening of the reflector.
  • a ballast can, for example, be accommodated between a side wall of the reflector and an outer end wall. As a result, the overall dimensions increase only insignificantly.
  • the reflector is connected to a holding device via supporting elements and a ballast is accommodated in this.
  • the reflector or the housing surrounding it. then very light and can be made of thin material. If the foot of a floor lamp serves as a holding device, the foot is weighted as desired.
  • the reflector preferably has at least one air opening on its side opposite the outlet opening. If, during operation, the radiation generator emits heat and the air inside the reflector is heated, chimney-like ventilation results through the outlet opening and air opening, so that favorable operating temperatures can be maintained.
  • the reflector 1 illustrated in FIG. 1 encloses a radiation generator, which here has the shape of a rod-shaped three-band fluorescent lamp 2.
  • the majority of the cross-section consists of an Archimedean spiral 3, the inner end section 4 of which is at such a distance from the zero axis 5 that not only the fluorescent lamp 2 has space, but also all the rays reflected from it, for example the Beam S1, bypassed the fluorescent lamp 2.
  • An Archimedean spiral is characterized in that it forms a constant angle of inclination ⁇ with all radial rays 6 emanating from the zero axis 5.
  • the outer end portion 7 of the reflector overlaps the inner end portion 4 by an angle ⁇ , which is chosen so that when looking into the outlet opening 8, which is formed between the outer end section 7 and the rest of the reflector, the radiation generator is no longer visible.
  • the overlap angle is not quite 60 ° in the present exemplary embodiment.
  • the overlapping end section 7 has a flat piece 9, which connects tangentially to the spiral 3, that is to say extends outside the dashed line 10, which represents a continuation of the spiral 3.
  • the beam S1 striking the inner end portion 4 is reflected four times before exiting the opening 8.
  • Another beam S2 is shown as an example and is reflected three times in total.
  • a third beam S3, shown as an example, is reflected twice. At least, however, a one-time reflection occurs, as the beam S4 shows. After the first reflection, all rays lie outside a region which is indicated by the dashed line 11. The angle of inclination ⁇ is selected at 77.5 ° so that the line 11 extends somewhat outside the inner end section 4.
  • the paths of the rays S1 to S4 can, however, also be understood as a projection of rays which have only one component in the plane of the drawing, but otherwise have a component in the direction of the zero axis 5.
  • 2 shows, reflecting side walls 12 and 13 are provided on the end faces of the reflector. These have an inclination with respect to the cross-sectional plane of the reflector, so that even rays that have only a small angle to the zero axis can still be guided to the outlet opening 8.

In this way, the fluorescent lamp 2, although it is completely inside of the reflector is included, can be easily installed.
