Description

[Technical field]

[0001] The present invention relates to a body irradiation device for applying directional actinic light to a living organism, in particular a human being, comprising at least one irradiation module, the at least one irradiation module comprising at least two LED light sources. [Background technology]

[0002] Body irradiation devices for living organisms, in particular the human body, are known, which are in particular configured in the form of a solarium with a bed or tanning table or red light treatment table, in which a light spectrum in a specific wavelength range is directed at the body or body parts, thereby influencing the cosmetic aspects, soundness, health or regeneration of the body or organism.

[0003] Typically in this case, such body irradiation devices use low-voltage light tubes, high-voltage light tubes or even high-voltage light lamps. In recent years, the use of LED light sources in body irradiation devices has been increasing.

[0004] Purely by way of example in this respect, reference is made to German Utility Model No. 202021100716, which relates to a body illumination device for illuminating the human body or parts of the human body with light rays which are in particular cosmetically and hygienically beneficial, the body illumination device having a radiation source with a base and at least one first LED chip and at least one second LED chip, the first LED chip being capable of emitting a first light spectrum with a first light peak and the second LED chip being capable of emitting a second light spectrum with a light peak different from the first light peak, the first LED chip and the second LED chip being arranged under a common lens in an LED housing and being separately controllable.

[0005] [Patent Document 1] German Utility Model No. 202021100716 Summary of the Invention [Problem to be solved by the invention]

[0006] It is an object of the present invention to provide an improved body illumination device, in particular to provide large area illumination from an LED light source in an improved body illumination device. [Means for solving the problem]

[0007] This problem is solved by the teaching of claim 1. Advantageous configurations are claimed in the dependent claims.

[0008] One aspect of the invention relates to a body irradiation device for applying directional actinic radiation to a living being, in particular a human being, comprising at least one irradiation module, the at least one irradiation module comprising: At least two LED light sources generating actinic light rays and arranged on a common support; a plate spanning the at least two first LED light sources; a space holder disposed between the plate and the support and configured to hold the plate and the support at a specified distance; and at least two plano-convex optical lenses materially bonded to the plate with the flat surfaces of the lenses facing the support, each one of the plano-convex optical lenses designed and arranged to at least substantially collimate or direct the light beam emitted from one of the LED light sources.

[0009] A body irradiation device in the sense of the present invention is preferably designed to irradiate a part of the body surface of a living being.

[0010] The term "actinic radiation" in the sense of the present invention refers to light or (broadband) radiation in the entire electromagnetic spectrum (see the definition in "Rompp Chemie-Lexikon", Thieme Verlag, Stuttgart, Germany) having a photochemical (including photobiochemical) action, whereby the light / rays may be of natural or artificial origin. In the claims and the description, "actinic light" or "actinic radiation" is used for light or radiation of artificial origin, preferably for light / rays emitted from a light source of a body irradiation device. The term "directed actinic radiation" as used in the present description and claims means actinic radiation that is more or less exclusively, if not exclusively, focused and directed at the target according to the present invention, i.e. a living organism, preferably a human being.

[0011] A lens in the sense of the present invention is an optical element. Preferably, at least one of the two surfaces is curved or spherical and curved. More preferably, the lens may be configured as a prism.

[0012] In a preferred embodiment of the body irradiation device, which can be implemented separately or together with one or two or more or all of the other features of the present invention, the actinic radiation can be a broad wavelength range of actinic radiation.Alternatively, but still preferably, the actinic radiation can be a narrow wavelength range of actinic radiation, or an actinic radiation of a specific wavelength or a number of specific wavelengths.This is well known to those skilled in the art, and they can select the wavelength or wavelength range or band to be used according to the requirements of each individual case.

[0013] Suitable examples for actinic radiation of wavelengths which can be used within the scope of the present invention are: Actinic rays with a wavelength λ in the range 280-315 nm (UV-B rays) and / or with a wavelength λ in the range 315-400 nm (UV-A rays) for tanning the human body, i.e. for activating the formation of melanin and its conversion into the dark (brown) form of the pigment naturally present in human skin, the tanning of the skin can be used for purposes in the health and / or cosmetic and / or medical fields. Actinic rays, in particular in the form of short-wave UV-B rays with a wavelength range λ of about 285 nm to 305 nm, or with a wavelength λ in the visible and near-IR (infrared) range (400 nm and above, better above 550 nm to 850 nm), for promoting vitamin D biosynthesis in human skin from vitamin D precursors, which actinic rays are irradiated on the human skin and promote the biosynthesis of compounds useful for the care and rejuvenation and regeneration of the skin, such as collagen, elastin, keratin, hyaluronic acid, etc.

[0014] A support within the meaning of the present invention is preferably a substrate and / or a printed circuit board.

[0015] Red spectrum in the sense of the present invention preferably means red visible light and / or infrared light.

[0016] The present invention is based on the recognition that when LED light sources are used in body illumination devices, a large number of LED light sources are required to ensure uniform illumination of the organism over a large area. This arises from the fact that, on the one hand, in order to achieve uniform radiation intensity on the organism's body, the emission angle of the LED light wave needs to be limited by a collimator, while, on the other hand, a collimated or directed light beam can only illuminate a smaller area due to the reduced emission angle.

[0017] Here, LED light sources replace the low-pressure tubes or high-pressure lamps that are typically used in body irradiation devices to irradiate large areas. The advantage of LED light sources is that they operate more energy-efficiently than tubes, and in particular generate less waste heat that needs to be dissipated. Furthermore, LED light sources have a longer life than tubes and therefore require less maintenance in body irradiation devices, which translates into significant cost savings, especially in the commercial sector.

[0018] Finally, the use of LED light sources allows the generation of a defined light spectrum and a defined light intensity at any location where such LED light sources are present. This is a major advantage over tubes that have different light intensities over their entire length. In particular at the ends of the tube the light intensity decreases. This is a disadvantage, since it is exactly in these areas of the tube that the foot and head regions of a person are irradiated, in which areas users of body irradiating devices generally want a particularly strong tan. The use of LED light sources can be particularly useful in these areas.

[0019] The use of a plate on which several lenses are fixed allows the individual lenses, and therefore also the different LED light sources, to be arranged relatively close to one another, thus achieving a uniform light intensity at the irradiation surface, which allows a much higher density at the LED light sources, especially compared to irradiation modules in which reflector collimators are used.

[0020] At the same time, however, the illumination module can be constructed relatively large, since the plate supported by the spacer on the support can span a large area of ​​the support on which the LED light sources are located.

[0021] The invention therefore makes it possible to combine two optimization goals that previously seemed incompatible when using LED light sources in body illumination devices: on the one hand, it is possible to guarantee a uniform illumination intensity on the illumination surface, and on the other hand, it is possible to illuminate a relatively large area with one illumination module.

[0022] A further advantage of the invention is that the LED light sources can be arranged on a common support, which is particularly efficient and cost-effective and also increases the strength of the overall illumination module, which can then be constructed to be relatively large.

[0023] The carrier here is preferably a conductor board or a substrate for the LED light source, and in both cases the carrier with the LED light source can be fastened in a particularly cost-effective manner compared to separate conductor boards and / or LED light sources arranged on a substrate.

[0024] The use of plates arranged at a defined distance from the support allows a particularly simpler construction to be realized in connection with this support, without a reflector collimator, which leads in particular to savings in material and manufacturing processes. Furthermore, contaminants such as dust particles, which impair the irradiation efficiency, can accumulate on the reflector.

[0025] In an advantageous configuration of the body illumination device, the plate is textured on the side facing away from the support, which scatters the light rays passing through the plate outside the lens area, thereby reducing or preferably preventing unevenness in the illumination intensity of the illumination surface due to the directed light rays exiting outside the lens.

[0026] In the region of the lens, the matte finish can be removed by material bonding, as long as the flat surface of the lens facing the support rests against the plate. In particular, the adhesive can be used to fill the unevenness on the plate caused by the matte finish, so that the plate becomes transparent again at this point. In the region of the lens, the light rays therefore pass through the plate unhindered.

[0027] In a further advantageous configuration of the body irradiation device, one side of the plate, in particular the side of the plate facing the support, is coated, in particular mirrored, and is reflective, in particular for light in the visible spectrum, which makes it possible to further reduce the emission of directed light outside the lens area.

[0028] In a further advantageous configuration of the body irradiation device, the at least two plano-convex lenses are press blank lenses. Press blank lenses are particularly economical to produce.

[0029] In a further advantageous configuration of the body irradiation device, the plate is a glass plate, which has a high strength and at the same time a high transmittance for light rays, and glass is furthermore particularly resistant to light rays, in particular ultraviolet light.

[0030] In a further advantageous configuration of the body irradiation device, at least one irradiation module further comprises an at least partially transparent plastic plate, which covers the plate, in particular on the side facing the support, and which has cutouts in the area of ​​at least two lenses, by providing the plastic plate, the actual plate is further strengthened and can cover this large area of ​​the irradiation module without the need for support.

[0031] In a further advantageous configuration of the body irradiation device, the plate is itself a partially transparent plastic plate. The use of a plastic plate is particularly economical. At the same time, the plastic plate can be processed particularly simply, for example by providing recesses in it.

[0032] In a further advantageous configuration of the body irradiation device, the plastic plate has, in particular, circular cutouts in the region of the at least two lenses, which are designed so that the at least two lenses can be materially connected to the plastic plate, which offers the advantage that, on the one hand, only one plastic plate can be used and, on the other hand, the passage of the lenses at high light intensities can be guaranteed by the cutouts.

[0033] In a further advantageous configuration of the body irradiation device, the recess forms a seat for the flat sides of at least two lenses. Such a seat can be configured in particular as a receiver or support for the flat sides of at least two lenses. Here, the seat is preferably formed as a protrusion or shoulder of the recess or in the recess. This allows the lenses to be fixed and centered or oriented in the recess particularly well.

[0034] In a further advantageous configuration of the body illumination device, the plate and / or the plastic plate have a fluorescent material, in particular are coated with a fluorescent material, which can indicate to the user of the body illumination device that the respective LED light source emits light in the area of ​​the fluorescent material. This is particularly important from the viewpoint of safety technology, for example in the case of ultraviolet light, which is harmful to the human eye.

[0035] In a further advantageous configuration of the body irradiation device, a first region of the plate and / or plastic plate contains a violet fluorescent material for a UV-A-LED light source, a second region of the plate and / or plastic plate contains a red fluorescent material for a red LED light source, and / or a third region of the plate and / or plastic plate contains a yellow fluorescent material for a UV-B-LED light source. By providing different fluorescent materials matched to the respective LED light sources, the fluorescence intensity can be increased. At the same time, the user can be visually informed about the type of light emitted respectively.

[0036] In a further advantageous configuration of the body irradiation device, the at least two plano-convex lenses are glass lenses. Glass is particularly resistant to light radiation, in particular ultraviolet light. Furthermore, the refractive index of glass makes it particularly suitable for optical elements.

[0037] In a further advantageous configuration of the body irradiation device, the at least two plano-convex lenses are silicone lenses. This allows the manufacturing process to be simplified, in particular the plate and / or the plastic plate and the lenses can be manufactured integrally in a single molding process. The plate is preferably made of silicone in this case and is further preferably supported by the plastic plate.

[0038] In a further advantageous configuration of the body irradiation device, at least one of the LED light sources emits UV-A light and the lens assigned to this LED light source for collimating the light beam is made of borosilicate glass, which is particularly transparent to UV-A light, so that particularly good energy efficiency can be achieved with low losses in the irradiation module.

[0039] In a further advantageous configuration of the body irradiation device, at least one of the LED light sources emits UV-B light and the lens assigned to this LED light source for collimating the light beam is made of quartz glass. Quartz glass has a very good transmittance for UV-B light. By using quartz glass for the lens, the light losses in the lens are minimized, so that a high energy efficiency of the irradiation module can be achieved.

[0040] In a further advantageous configuration of the body irradiation device, the material bond is a UV-curable adhesive, which has the advantage that it is UV-resistant, so that the material bond is not weakened by irradiation with UV rays, but rather hardened further.

[0041] In a further advantageous configuration of the body irradiation device, at least one of the LED light sources comprises a first LED chip with a first light spectrum and a second LED chip with a second light spectrum different from the first light spectrum, thereby making it possible to realize a relatively broadband light spectrum.

[0042] In a further advantageous configuration of the body irradiation device, at least one first LED light source has a first light spectrum and at least one second LED light source has a second light spectrum, so that different areas with different light spectra can be realized in the individual light modules.

[0043] In a further advantageous configuration of the body illumination device, the first region of the plate is arranged around a lens for collimating the light of the first LED light source or the first LED chip, and the second region of the plate is arranged around a lens for collimating the light of the second LED light source or the second LED chip, thereby allowing the phosphor material to be arranged in different regions of the plate around the respective LED light source.

[0044] In a further advantageous configuration of the body irradiation device, the first LED chip and / or the first LED light source emits in the UV-A or UV-B spectrum and the second LED chip and / or the second LED light source emits in the red spectrum. In this embodiment, both tanning of the user and deep heating of the user's tissues are achieved.

[0045] In a further advantageous configuration of the body irradiation device, the irradiation module further comprises a cooling device, which is designed to cool the support at least on the side facing away from the at least two LED light sources.

[0046] In a further advantageous configuration of the body irradiation device, it further comprises an exposure tunnel capable of surrounding the living organism, the exposure tunnel being formed from at least one lower part of the body irradiation device having a surface made of a material substantially transparent to actinic radiation, and at least one upper part of the body irradiation device, the surface separating an internal space in which the living organism is exposed to actinic radiation from an external space, in which at least one LED irradiation module is mounted so as to emit actinic radiation through the surface, and the upper part also comprising at least one LED irradiation module mounted so as to emit actinic radiation into the internal space.

[0047] Further advantages and features emerge from the following description of an embodiment, taken in conjunction with the drawings, which are at least partly schematic. [Brief description of the drawings]

[Diagram 3] FIG. 3 is an exploded view of the illumination module of FIG. 2. [Figure 4] FIG. 4 is a further exploded view of the components of the support of the illumination module of FIG. 2 or FIG. 3; [Diagram 5] FIG. 5 is a cross-sectional view of a part of the illumination module of FIG. 2, 3 or 4. [Figure 6] FIG. 2 is a cross-sectional view of a further embodiment of an illumination module; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0049] Figure 1 shows a body irradiation device 1. It has an exposure tunnel 16 in which a user can lie to be exposed to actinic radiation.

[0050] Preferably, the exposure tunnel 16 is closed after the user has entered the exposure tunnel 16 by substantially pivoting the upper portion 28 of the body irradiation device 1 towards the lower portion 27 of the body irradiation device 1 .

[0051] The lower part 27 of the body irradiation device 1 has an at least substantially transparent surface 17, under which the irradiation module 2 with the LED light sources 3, 4 is arranged. The surface 17 here separates the exposure tunnel 16 into an inner space 19 and an outer space 20 in which the irradiation module 2 is arranged. The outer space 20 can be cooled in particular by an air flow.

[0052] FIG. 2 shows a plan view of the irradiation module 2 of the body irradiation device 1 .

[0053] The illumination module 2 comprises a plate 6 on which plano-convex lenses 7, 8 are arranged. These lenses 7, 8 are preferably materially connected to the plate 6. Furthermore, the lenses are preferably connected to the plate 6 on a side 9 facing away from the support 5 (not shown), in particular arranged on a surface of this side 9. The illumination module 2 further comprises spacers 21a, 21b, 21c, 21d, the upper ends or fixing means of which are visible in FIG.

[0054] Furthermore, in FIG. 2, parts of a fixing frame 24 of the irradiation module 2 are visible, the fixing frame having holes into which screws (without reference numbers) are introduced to fix the fixing frame 24 to the body irradiation device 1 .

[0055] FIG. 3 is an exploded view of the illumination module 2 of FIG.

[0056] The plates 6 shown in Fig. 2 are shown in an exploded view. The plates 6 are preferably glass plates, each having lenses 7, 8 materially bonded to their surface 9, in particular glued thereto.

[0057] The surface 9 of the plate 6 is preferably textured. This texture is preferably removed in the region of the lenses 7, 8 by using an adhesive, so that the interface between the flat surfaces of the lenses 7, 8 and the plate 6 is transparent. On the side of the plate 6 facing the conductor track plate 5, which preferably forms the carrier 5, a plastic plate 11 is preferably arranged. The plastic plate preferably has cut-outs 12, 13, which are cut out in the regions of the plastic plate 11 that correspond to the arrangement of the lenses 7, 8 on the plate 6.

[0058] Alternatively, the surface 10 of the plate 6 facing the support 5 can also be matte finished.

[0059] The plastic plate 11 is preferably made of or comprises a fluorescent material, which can be excited to fluoresce on the conductor board 5 by the light beam from the LED light sources 3, 4.

[0060] The plastic plate 11 is preferably fixed and oriented or positioned to the plate 6 by a fixing plate 22 which surrounds the plastic plate 11 at its end faces.

[0061] On the right side of the exploded view of FIG. 3, a conductor circuit board is arranged, on which the LED light sources 3, 4 are arranged, fixed and electrically wired.

[0062] A cooling device 23, in this case cooling ribs 23, is arranged on the side of the conductor board 5 facing away from the plate 6. Between the cooling device 23 and the conductor board 5, a thermal paste is preferably applied.

[0063] The irradiation module 2 can be preferably fixed by a support frame 24. In this embodiment, the support frame 24 supports the cooling means 23 and the conductor track plate 5 fixed to the cooling means 23. The plate 6, the fixing plate 22 and thus also the plastic plate 11 are fixed to the cooling means 23 by means of screws (without reference numbers). More preferably, however, they can be fixed directly to the support frame 24. Between the plate 6 and / or the plastic plate 11 and the conductor track plate 5, spacers 21a, 21b, 21c, 21d are provided which adjust a defined distance. These can also be arranged between the fixing plate 22 and the plate 6 and / or between the fixing plate 22 and the conductor track plate 5 or the cooling means 23 or the support frame 24, depending on how the screw fixing is carried out.

[0064] FIG. 4 shows an exploded view of the entire unit shown in FIG.

[0065] As can be seen from this figure, the support frame 24 can be fixed to the cooling device 23 in this embodiment by means of screws.

[0066] Figure 5 shows a cross-sectional view of the irradiation module 2 of Figures 2 to 4. Figure 5 is schematic and therefore differs slightly from the actual embodiment of Figures 2 to 4. The cooling device 23 is also not shown in Figure 5, but can be arranged on the underside of the support 5.

[0067] From top to bottom, the individual elements of the illumination module 2 are arranged in FIG. 5 as follows: The flat sides of the plano-convex lenses 7, 8 are materially connected to the glass plate 6. Here, the side 9 of the glass plate facing away from the carrier 5 is preferably matte-finished. Under the glass plate 6, a plastic plate 11 is arranged, which has cutouts 12, 13 in the area of ​​the lenses 7, 8. The side 10 of the glass plate 6 facing the carrier 5 is preferably mirror-finished. Alternatively, the glass plate 6 can be free of matte-finishing and / or mirror-finishing. Furthermore, alternatively or additionally, matte-finishing and / or mirror-finishing can be performed on the respective other side of the glass plate 6.

[0068] The plastic plate 11 preferably comprises a fluorescent material which can be excited by the LED light sources 3, 4. The light sources 3, 4 are arranged in the region of the optical axes of the lenses 7, 8, respectively, so that a large part of the light emitted by the LED light sources 3, 4 passes through the cutouts 12, 13 into the lenses 7, 8 and can be at least substantially collimated there.

[0069] Regarding the support 5 with the LED light sources 3, 4 there are essentially two different embodiments, both of which are illustrated in FIG.

[0070] However, typically only one of the two embodiments will be realised in a single illumination module 2. The illustration of both embodiments here is particularly illustrative.

[0071] Here, the support 5 is held at a defined distance to the plastic plate 11 and / or the glass plate 6 by space holders 21a, 21b, 21c.

[0072] The alternative embodiment differs in that the carrier 5 is formed by a conductor track plate, on which in this case, as shown on the left, a substrate 18 is arranged, on which the LED chip 14 can ultimately be arranged, which LED chip is designed to emit light rays.

[0073] Alternatively, the carrier 5 itself can also be configured as a substrate, in which case the LED chip 14 or, if the LED light source has two LED chips, the LED chips 14, 15, as shown on the right side of Fig. 5, are arranged directly on the carrier 5. The LED light sources 3, 4 and the conductor plate 5 are here configured as known from the prior art.

[0074] FIG. 6 shows a cross-sectional view of a further embodiment of the illumination module 2.

[0075] The embodiment shown in Fig. 6 differs from the embodiment shown in Fig. 5 essentially in that only a plate 6 is present in the upper region of the illumination module 2. This plate 6 is preferably designed as a plastic plate.

[0076] In this embodiment, the cutouts 12, 13 have two hole diameters, where the lower hole diameter is reduced relative to the upper hole diameter, thus forming a nose, protrusion or shoulder which forms a seat 25, 26 for the lenses 7, 8, respectively, which is preferably circular like the lenses 7, 8.

[0077] The lenses 7, 8 are preferably materially fixed, in particular adhesively, to the bases 25, 26. The lenses 7, 8 are also here oriented or centered by the bases 25, 26, respectively, such that the flat surfaces of the lenses 7, 8 preferably extend at least substantially parallel to the support 5. Preferably in this embodiment, the side 10 of the plastic plate 6 facing the support 5 is mirrored, and the plastic plate 6 further preferably also comprises a fluorescent material.

[0078] Preferably, different areas of the plastic plates 6, 11 of figures 5 and 6 can be provided with fluorescent materials which fluoresce different colours, preferably with fluorescent dyes which are adapted to the emission spectrum of the respective LED chips of the LED light sources 3, 4.

[0079] With regard to the LED light sources 3, 4 and the carrier 5, what has already been said in connection with Fig. 5 applies. In Fig. 6, two further embodiments of the LED light sources 3, 4 are again shown, which are also suitable for the embodiment of Fig. 5 (and vice versa). Here, the LED chip 14 is once again arranged on the left side directly on the substrate 18, while on the right side the carrier 5 represents a conductor track plate. An additional substrate 18 is provided, on which two LED chips are arranged, preferably with different light spectra.

[0080] It should be noted that the embodiments are merely examples and do not limit the scope of protection, application and structure in any way. Rather, the above description provides a guideline for a person skilled in the art to implement at least one embodiment, whereby various modifications can be made with respect to the function and arrangement of the components specifically described without departing from the scope of protection as obtained from the combination of the claims and their equivalent features.
