[0014] The term "actinic radiation" within the meaning of the invention means light or (broader) radiation of the entire electromagnetic spectrum (see definition in "Römpp Chemie-Lexikon", Thieme Verlag, Stuttgart, Germany) that has a photochemical (including photobiochemical) effect and optionally includes light / radiation 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 light / radiation emitted by radiation sources in a body irradiation device.

[0015] In a preferred embodiment of the body irradiation device, which can be implemented separately or together with one or two or more or all other features of the invention, the actinic radiation can be broad-wavelength actinic radiation. Alternatively, although also preferred, the actinic radiation can be narrow-wavelength actinic radiation or even actinic radiation of a specific wavelength or several specific wavelengths. This is known to the person skilled in the art, who can select the wavelength(s) or wavelength ranges or bands to be used according to the requirements of the individual case.

[0017] UV-A radiation within the meaning of the invention is actinic radiation, preferably with a wavelength in the range from 315 to 400 nm.

[0018] Short-wave UV-B radiation within the meaning of the invention is actinic radiation in the wavelength range from approximately 298 to 315 nm.

[0019] UV-B radiation particularly promotes the formation of new pigments, especially melanin formation. UV-A radiation particularly promotes the tanning of pigments, especially melanin conversion. Shortwave UV-B radiation particularly promotes vitamin D biosynthesis of vitamin D precursors in human skin.

[0020] IR radiation (infrared radiation) within the meaning of the invention is actinic radiation, preferably in a wavelength band of 400 nm, in particular greater than 550 nm to 850 nm. IR radiation promotes in particular the biosynthesis of useful compounds for the care, rejuvenation and regeneration of the skin, such as collagen, elastin, ceratin and hyaluronic acid.

[0021] "Approximately" in the context of wavelength specifications within the meaning of the invention means + / - 2 nm. Monochromatic LEDs preferably have such a wavelength band around the characteristic wavelength. An LED radiation source within the meaning of the invention preferably has a single LED chip or multiple LED chips. Alternatively or additionally, the LED radiation source has a receptacle and / or a circuit for the LED chip(s). LED stands for "light-emitting diode."

The program can be designed in such a way that it embodies or is capable of executing the methods described here, so that the CPU can execute the steps of such methods.In particular, a control means within the meaning of the invention is a software-implemented controller or a control device.

[0023] The term UV radiation in the sense of the invention includes UV-A radiation and UV-B radiation.

[0024] The term radiation intensity in the sense of the invention is preferably synonymous with the term irradiance.

[0025] The term specific in the sense of the invention preferably means predefined.

[0026] The invention is based on the finding that the use of UV-A LEDs and UV-B LEDs as radiation sources enables targeted emission in the UV spectrum and in the UV-B spectrum.

[0027] The invention makes it possible to arrange a large number of LED radiation sources of the UV-A and UV-B spectrum in a comparatively small space in such a way that, on the one hand, a homogeneous radiation field can be generated with respect to the different radiation spectra, and, on the other hand, LED radiation sources with different radiation spectra can be controlled separately. This allows emission spectra to be combined in a controlled manner and also controlled with regard to the respective emitted intensities and total emitted radiation doses of the various radiation spectra of the LEDs.

[0028] The radiation intensity and / or radiation dose emitted by the first radiation sources and the radiation intensity and / or radiation dose emitted by the second radiation sources can preferably be individually changed by the control means.

[0029] The invention makes it possible to utilize different time sequences of photobiological effects and to separate these photobiological effects. For example, pigment formation can be treated separately from pigment tanning. Furthermore, different irradiation scenarios can be implemented by a single user.

[0030] Furthermore, by providing multiple circuits with the same radiation spectrum, different areas of the body or a body part can be controlled differently depending on the desired effect and the photobiological sensitivity of the user. In particular, a user's facial area can be irradiated differently than the rest of the body.

[0031] In an advantageous embodiment, the at least one irradiation module further comprises: at least one first circuit board on which the first LED radiation sources are arranged; and at least one second circuit board on which the second LED radiation sources are arranged; wherein the first circuit board has first regions and the second circuit board has second regions, wherein the first regions overlap with the second regions, and wherein a first LED radiation source is arranged in at least one first region and a second LED radiation source is arranged in at least one second region.

[0032] By providing different circuit boards for the different LED radiation sources, they can be controlled separately. Furthermore, the individual types of LED radiation sources can be replaced separately by replacing individual circuit boards. This is particularly advantageous because UV-B LEDs have a shorter service life than UV-A LEDs. In particular, UV-B LEDs exhibit a higher power loss over time than UV-A LEDs. The overlapping areas of the circuit boards and a corresponding arrangement of radiation sources in these areas nevertheless ensure that a sufficiently homogeneous UV-A radiation field and a sufficiently homogeneous UV-B radiation field are generated in the same spatial section.

[0033] In a further advantageous embodiment, the at least one first circuit board and the at least one second circuit board are arranged essentially alternately in the longitudinal direction of the body irradiation device. This also ensures that a sufficiently homogeneous UV-A radiation field and a sufficiently homogeneous UV-B radiation field are generated in the longitudinal direction of the body irradiation device.

[0034] In a further advantageous embodiment of the body irradiation device, the first circuit board has at least one first circuit and the second circuit board has at least one second circuit, wherein the at least one first circuit interconnects the first LED radiation sources, wherein the at least one second circuit interconnects the second LED radiation sources, and wherein the circuit boards have separate electrical connections for the at least one first and the at least one second circuit.

[0035] This allows for improved controllability of the different types of LED radiation sources.

[0036] In a further advantageous embodiment, the body irradiation device further comprises an exposure tunnel in which a user can lie down to be irradiated with actinic radiation, wherein the exposure tunnel is closed by essentially pivoting an upper part of the body irradiation device toward a lower part of the body irradiation device, wherein the lower part of the body irradiation device has an at least substantially transparent surface, beneath which irradiation modules are arranged; and wherein irradiation modules are also arranged on the upper part.

[0037] This design is particularly advantageous if a user is to receive a full-body treatment while lying down.

[0038] In an advantageous embodiment, the body irradiation device has more first LED radiation sources than second LED radiation sources. To achieve a lasting tanning effect, it is advantageous to generate a higher radiation intensity in the UV-A range than in the UV-B range. In particular, UV-B has a higher erythema-effective radiation intensity on the skin of a user at the same nominal (physical) radiation intensity as UV-A. Therefore, to achieve a photobiological effect, it is advantageous to provide more emitted UV-A radiation intensity than UV-B radiation intensity. This can be achieved, among other things, by the respective number of LED radiation sources in the respective wavelength range.

[0039] In a further advantageous embodiment of the body irradiation device, the number of first LED radiation sources is selected such that an operating voltage of the at least one first circuit does not exceed approximately 70 V, preferably approximately 60 V, more preferably approximately 48 V, even more preferably approximately 36 V. Alternatively or additionally, the number of second LED radiation sources is also selected such that an operating voltage of the at least one second circuit does not exceed approximately 70 V, preferably approximately 60 V, more preferably approximately 48 V, even more preferably approximately 36 V.

[0040] This eliminates the need for any or only minimal separate insulation for the circuits. This simplifies the manufacture of the irradiation modules and makes them more cost-effective.

[0041] In a further advantageous embodiment of the body irradiation device, the first LED radiation sources and the second LED radiation sources are arranged offset. This also allows for a particularly homogeneous radiation field of the irradiation modules to be achieved.

[0042] In a further advantageous embodiment of the body irradiation device, the circuit board has separate electrical connections for each of the first circuits and / or separate connections for each of the second circuits.

[0043] This allows each of the circuits to be controlled separately.

[0044] In a further advantageous embodiment of the body irradiation device, the first LED radiation sources cover different bands, in particular frequency bands and / or wavelength bands, of the UV-A spectrum, wherein the first circuits interconnect first LED radiation sources each of a single defined band of the UV-A spectrum and / or wherein the second LED radiation sources cover different bands of the UV-B spectrum, wherein the second circuits interconnect second LED radiation sources each of a single defined band of the UV-B spectrum.

[0045] This allows any number of wavelength ranges of LEDs to be combined in individual circuits. Depending on the activation or control of the individual circuits and the associated radiation spectrum, various effects and / or types of therapy can be generated. This allows, for example, body irradiation devices, especially tanning beds, of different UV classes to be implemented in a single device. Preferably, multiple devices with a fixed, i.e., non-modifiable, radiation source configuration can be implemented in a single body irradiation device.

[0046] In a further advantageous embodiment of the body irradiation device, the second LED radiation sources are designed to emit UV-B radiation from the following group of bands: approximately 297 nm, approximately 308 nm, approximately 311 nm, approximately 312 nm and / or approximately 280 nm to approximately 315 nm.

[0047] All of these wavelengths produce a photobiological effect in humans. A particularly high photobiological effect can be achieved at low radiation intensity at a wavelength of 308 nm. This is where the radiation intensity of the second LED radiation sources preferably peaks.

[0048] In a further advantageous embodiment, the body irradiation device further comprises: third radiation sources which are configured to emit further actinic radiation, in particular IR radiation, wherein the circuit board has at least one third circuit, wherein third circuits interconnect third radiation sources, and wherein the circuit board additionally has separate electrical connections for the at least one third circuit.

[0049] By providing means for emitting additional types of actinic radiation, further photobiological effects can be activated by the body irradiation device. Preferably, the first circuit connects exclusively first radiation sources, the second circuit connects exclusively second radiation sources, and / or the third circuit connects exclusively third radiation sources.

[0050] In a further advantageous embodiment of the body irradiation device, at least two circuits intersect on the circuit board, with each circuit having a bridge. This allows for particularly homogeneous radiation distribution with respect to the LED radiation sources with different radiation spectra. In particular, these can be arranged alternately in the direction of a radiation surface.

[0051] In a further advantageous embodiment of the body irradiation device, the irradiation module has a transparent plate which spans the first LED radiation sources and the second LED radiation sources, wherein the plate is spaced from the circuit board and at least one side of the plate, in particular the side of the plate facing away from the circuit board, is satin-finished.

[0052] Furthermore, the satin finish of the transparent plate allows for the light emitted by the LED radiation sources to be diffused. This also contributes to a particularly homogeneous irradiation of the body. Therefore, the plate is preferably the sole optical system of at least one irradiation module. Eliminating the need for additional optical elements such as lenses or collimators, as well as their installation, reduces the manufacturing costs of the irradiation modules.

[0053] In a further advantageous embodiment of the body irradiation device, the plate is a glass plate.

[0054] Glass has good resistance to UV radiation.

[0055] In a further advantageous embodiment of the body irradiation device, a radiation angle of the first LED radiation sources and / or the second LED radiation sources does not exceed approximately 50°, preferably approximately 40°, more preferably approximately 30° and most preferably approximately 45°.

[0056] By using LED radiation sources with a comparatively small beam angle, a particularly simple structure can be realized without reflector collimators and without lenses for collimating the emitted radiation, which nevertheless achieves good homogeneity of the irradiation, ie a homogeneous distribution of the radiation dose on a surface to be irradiated.

[0057] In a further advantageous embodiment of the body irradiation device, the irradiation module further comprises an at least partially transparent plastic plate which covers the plate, in particular on the side facing the circuit board, and has recesses in the region of the first LED radiation source and / or in the region of the second LED radiation source.

[0058] Depending on the design of the plastic plate, this can shade certain areas of the body.

[0059] The plastic plate preferably comprises a fluorescent material, in particular, it is coated with the fluorescent material. In this case, the plastic plate serves as an optical control function for the user who has difficulty perceiving UV radiation, or who, for example, cannot perceive it in the short-wave UV-B range. The fluorescent plastic disc signals to the user whether radiation potentially harmful to the eyes or skin is present. The fluorescent material converts the UV radiation at least partially into visible light.

[0060] In a further advantageous embodiment of the body irradiation device, the plate, in particular on the side facing away from the circuit board, has an engraving in the region of the first LED radiation source and / or in the region of the second LED radiation source, preferably in the form of a ring, more preferably in the form of several concentric rings.

[0061] The engraving(s) create a particularly well-suited control element that illuminates when visible light hits the engraving(s). This increases user safety.

[0062] In a further advantageous embodiment of the body irradiation device, the first LED radiation sources and the second LED radiation sources are controlled in such a way that the radiation intensity of the first LED radiation sources of the at least one first circuit and / or a radiation intensity of the second LED radiation sources of the at least one second circuit varies over time.

[0063] By varying the timing of irradiation, different time sequences of photobiological effects can be utilized and these photobiological effects can be separated. For example, UV-B radiation can be applied first to promote pigment formation, followed by UV-A radiation to induce pigment tanning.

[0064] In a further advantageous embodiment, the body irradiation device comprises a sensor configured to measure at least one physiological parameter, in particular a pigmentation and / or a reaction of the skin of the living being to an irradiation dose, wherein the first LED radiation sources and the second LED radiation sources are controlled in such a way that the radiation intensity or radiation intensities vary depending on the at least one physiological parameter.

[0065] By taking physiological parameters into account, a treatment process can be tailored to the individual user. Furthermore, it is possible for a user to set the desired treatment outcome, and the radiation treatment can be adjusted accordingly. Such radiation outcomes can include, for example, a pre-tan, a color, or a degree of tan.

[0066] In a further advantageous embodiment, the body irradiation device has a user interface which is set up in such a way that a radiation intensity to be emitted and / or a radiation dose of UV-A radiation to be emitted and a radiation intensity to be emitted and / or a radiation dose of UV-B radiation to be emitted can be set, in particular individually, by means of the user interface as a function of a maximum permissible erythema-effective radiation intensity of UV radiation, and wherein the first LED radiation sources and the second LED radiation sources (5) are controlled on the basis of a selection of the radiation intensity to be emitted and / or the radiation dose of UV-A radiation to be emitted and the radiation intensity to be emitted and / or the radiation dose of UV-B radiation to be emitted at the user interface.

[0067] The use of UV LEDs as radiation sources allows for individual adjustment of the radiation intensity. The user can specify the UV radiation intensity they are exposed to via the user interface. They can also adjust the radiation spectrum to which they are exposed. The maximum permissible erythema-effective radiation intensity serves as a reference value for setting the radiation intensity. This can be a legally prescribed value or a freely selected value within legal requirements.

[0068] In a further advantageous embodiment of the body irradiation device, a temporal profile of the radiation intensity of the UV-A radiation to be emitted and a temporal profile of the radiation intensity of the UV-B radiation to be emitted can additionally be set via the user interface, wherein the first LED radiation sources and the second LED radiation sources are additionally controlled on the basis of a selection of a temporal profile.

[0069] By considering the temporal progression of irradiation, different time courses of photobiological effects can be utilized and these photobiological effects can be separated. For example, UV-B radiation can be applied first to promote pigment formation, followed by UV-A radiation to induce pigment tanning.

[0070] In a further advantageous embodiment, the body irradiation device further comprises a user interface, wherein at least one irradiation scenario is stored in the means for controlling, for which a maximum permissible erythema-effective radiation intensity of UV radiation is defined and which comprises a plurality of irradiation profiles, wherein the plurality of irradiation profiles each define a radiation intensity to be emitted and / or a radiation dose of UV-A radiation to be emitted and a radiation intensity to be emitted and / or the radiation dose of UV-B radiation to be emitted as a function of the maximum erythema-effective radiation intensity of UV radiation, wherein the user interface is configured in such a way that the plurality of irradiation profiles can be selected,and wherein the first LED radiation sources and the second LED radiation sources are controlled based on a selection of one of the plurality of irradiation profiles at the user interface.,

[0071] Preferably, the control means stores a plurality of irradiation scenarios, which can be selected via the user interface, with a different maximum permissible erythema-effective UV radiation intensity being defined for each irradiation scenario. Furthermore, the irradiation profiles preferably additionally define a temporal progression of the UV-A radiation intensity to be emitted and a temporal progression of the UV-B radiation intensity to be emitted via the user interface.

[0072] The use of UV LEDs as radiation sources makes it possible to define irradiation profiles that define the radiation spectrum in terms of radiation intensity in individual ranges of the irradiation spectrum. Furthermore, irradiation profiles can also be used to define the temporal progression of an irradiation. This significantly simplifies treatment settings for the user and thus ensures maximum treatment efficiency while simultaneously increasing safety. If there are multiple irradiation scenarios, the boundary conditions for treatment with the various irradiation profiles can be set using these. For example, the maximum permissible erythema-effective radiation intensity, which serves as a reference, can be set using the irradiation scenarios.In addition, the irradiation scenarios and irradiation profiles can be used to optimally adjust the mood or atmosphere of a treatment with actinic radiation. Possible parameters include: temperature in the treatment room, light color in the treatment room, background noise in the treatment room, odor in the treatment room, misting in the treatment room, ventilation in the treatment room, and / or the addition of warming infrared radiation to the UV radiation. The irradiation scenario generally specifies which parameters are activated and which value ranges are possible. The irradiation profiles then define specific values ​​or temporal value progressions of the parameters.

[0073] The temporal progression of the irradiation profiles can extend over one or several treatment sessions, especially over several days. This can be advantageous, for example, with regard to controlled pigment formation.

[0074] In a further advantageous embodiment of the body irradiation device, the user interface is designed such that the multiple irradiation profiles can be selected, in particular continuously, between a maximum radiation profile with the highest radiation intensity to be emitted and / or the radiation dose to be emitted and at least one radiation profile with a lower radiation intensity to be emitted and / or the radiation dose to be emitted. This allows for particularly fine adjustment of the parameters of an irradiation profile.

[0075] In a further advantageous embodiment of the body irradiation device, the radiation intensity to be emitted and / or the radiation dose to be emitted of the UV-A radiation varies between different irradiation profiles differently than the radiation intensity to be emitted and / or the radiation dose to be emitted of the UV-B radiation.

[0076] This allows photobiological effects to be optimized.

[0077] In a further advantageous embodiment, the body irradiation device has at least two of the irradiation profiles from the following group of irradiation profiles: Morning Intensive, Morning Medium, Morning Sensitive, Midday Intensive, Midday Medium, Midday Sensitive, Evening Intensive, Evening Medium and Evening Sensitive, whereby at 100% UV-A radiation and 100% UV-B radiation, at least substantially the maximum permissible erythema-effective radiation intensity of UV radiation is achieved, whereby the irradiation profiles are defined in the following table: In a further advantageous embodiment of the body irradiation device, the at least one irradiation module further comprises: third LED radiation sources which are designed to emit red radiation and / or infrared radiation, wherein the control means are configured to control the third LED radiation sources in such a way that a specific radiation intensity and / or a specific radiation dose of red radiation and / or infrared radiation is emitted.

[0078] By adding red and / or infrared radiation, the mood or atmosphere in the treatment room can be specifically influenced. Infrared radiation can also achieve additional photobiological effects.

[0079] In a further advantageous embodiment of the body irradiation device, the irradiation profiles from the group of irradiation profiles are further defined as follows, wherein at 100% red radiation at least substantially the maximum permissible radiation intensity of red radiation and / or infrared radiation is achieved:

[0080] In a further advantageous embodiment of the body irradiation device, the at least one irradiation module further comprises: fourth LED radiation sources which are designed to emit radiation in the visible spectrum and which are connected in series with the second LED radiation sources in a second circuit.

[0081] Alternatively or additionally, the fourth LED radiation sources have the same power supply as the second LED radiation sources. Alternatively or additionally, the fourth LED radiation sources are controlled by the control means together with the second LED radiation sources in such a way that the fourth LED radiation sources are always activated when the second LED radiation sources are activated.

[0082] One or all of these configurations ensure that the fourth LED radiation sources are always activated together with the second LED radiation sources, which emit UV-B radiation, and in doing so emit light in the visible spectrum that a user can perceive. Depending on the radiation spectrum, the UV-B radiation is barely visible to a user or not at all. Since UV-B radiation can damage the user's skin and / or eyes, it is therefore an additional safety aspect that the user can perceive when the second LED radiation sources are emitting radiation. In addition, the fourth LED radiation sources can also be used to create a defined mood or atmosphere in the treatment room. The fourth radiation sources are therefore preferably yellow.

[0083] In a further advantageous embodiment of the body irradiation device, in a section of the irradiation module in the longitudinal direction of the body irradiation device, in which a face of the living being is arranged during intended use, more first LED radiation sources and / or second LED radiation sources are arranged than in other sections of the body irradiation device.

[0084] This ensures that a user experiences a higher radiation dose in the facial area than in the rest of the body. At the same time, the LED radiation sources in the facial area can be controlled in essentially the same way as in other areas of the body irradiation device, in particular with the same control current.

[0085] In a further advantageous embodiment of the body irradiation device, the number of second LED radiation sources of the at least one irradiation module is selected such that they can be operated at less than 70%, preferably less than 60%, most preferably at 50% of the rated current or rated power of the second LED radiation sources in order to emit the specific radiation intensity of UV-B radiation and / or to emit the specific radiation dose of UV-B radiation within a predetermined time. UV-B LEDs are characterized by the fact that their performance decreases significantly over their service life. By reducing the control current and / or the output power, the service life of the second LED radiation sources can be increased. Ideally, a sufficient radiation intensity of the second LED radiation sources is ensured over the entire service life of the body irradiation device.

[0086] In a further advantageous embodiment of the body irradiation device, the at least one irradiation module has a housing with end faces, wherein air-permeable regions for air supply are provided on the end faces and an opening for air discharge is provided in a central region of the housing.

[0087] This allows the first and second LED radiation sources as well as other electronic and electrical components installed in the irradiation module to be cooled efficiently without affecting the treatment room.

[0088] In a further advantageous embodiment of the body irradiation device, the opening of the housing of the at least one irradiation module is connected to an air duct in an upper part or in a lower part of the body irradiation device and the air duct leads to a fan in the lower part of the body irradiation device.

[0089] This eliminates the need to install a separate fan for each irradiation module or multiple irradiation modules. This reduces energy consumption and noise pollution.

[0090] The features and advantages mentioned with respect to the first aspect of the invention also apply to the second and third aspects of the invention accordingly and vice versa.

[0091] In an advantageous embodiment of the method, the circuits are controlled in such a way that a radiation intensity of the first LED radiation sources of the at least one first circuit and / or a radiation intensity of the second LED radiation sources of the at least one second circuit vary over time.

[0092] This allows the temporal separation of photobiological effects to be exploited, for example with regard to pigment formation and subsequent pigment tanning.

[0093] In a further advantageous embodiment of the method, the radiation intensity or intensities vary according to a predefined temporal profile. In a further advantageous embodiment, the method comprises the following work step:

[0094] Measuring at least one physiological parameter, in particular a pigmentation and / or a reaction of the skin to a radiation intensity and / or radiation dose of the living being, wherein the radiation intensity or radiation intensities and / or radiation dose vary depending on the at least one physiological parameter.

[0095] This allows a user to set the desired treatment outcome, and the radiation is adjusted accordingly. Such radiation outcomes can include, for example, a pre-tan, a color, or a degree of tan.

[0096] In a further advantageous embodiment of the method, the at least one first and / or the one second circuit are controlled in such a way that the first LED radiation sources emit approximately 98% and the second LED radiation sources emit approximately 2% of a radiation intensity generated by the body irradiation device.

[0097] This achieves a particularly good tanning effect.

[0098] In a further advantageous embodiment of the method, the at least one first and / or the at least one second circuit are controlled separately in a pulsed manner.

[0099] In a further advantageous embodiment of the method, the at least one third circuit is also controlled in such a way that a specific radiation profile and / or a specific radiation dose is / are emitted.

[0100] Further preferably, the radiation intensity of the further actinic radiation of the third radiation sources is also varied over time.

[0101] In a further advantageous embodiment, the method comprises the following work step:

[0102] Detecting a, in particular individual, selection of a radiation intensity to be emitted and / or a radiation dose to be emitted of UV-A radiation and a radiation intensity to be emitted and / or a radiation dose to be emitted of UV-B radiation as a function of a maximum permissible erythema-effective radiation intensity of UV radiation; wherein the first LED radiation sources and the second LED radiation sources are controlled on the basis of the selection of the radiation intensity to be emitted and / or the radiation dose to be emitted of UV-A radiation and the radiation intensity to be emitted and / or the radiation dose to be emitted of UV-B radiation.

[0103] In a further advantageous embodiment, the method comprises the following work step:

[0104] Providing at least one irradiation scenario for which a maximum permissible erythema-effective radiation intensity of UV radiation is defined and which comprises several irradiation profiles;

[0105] Detecting a selection of an irradiation profile from the plurality of irradiation profiles, each of which defines a radiation intensity to be emitted and / or a radiation dose of UV-A radiation to be emitted and a radiation intensity to be emitted and / or the radiation dose of UV-B radiation to be emitted as a function of the maximum permissible erythema-effective radiation intensity of UV radiation; wherein the first LED radiation sources and the second LED radiation sources are controlled based on the selection of one of the plurality of irradiation profiles.

[0106] In a further advantageous embodiment, the method comprises the following work step:

[0107] Recording a selection of an irradiation scenario from several irradiation scenarios, whereby a different maximum permissible erythema-effective radiation intensity of UV radiation is defined for each irradiation scenario.

[0108] In a further advantageous embodiment of the method, the second LED radiation sources are operated with less than 70%, preferably less than 60%, most preferably with approximately 50% of the rated current or the rated power of the second LED radiation sources.

[0109] In a further advantageous embodiment of the method, the first LED radiation sources and the second LED radiation sources are controlled in different sections in the longitudinal direction of the body irradiation device, in particular on different circuit boards, in such a way that different radiation intensities and / or radiation doses are emitted in different sections.

[0127] Figure 15: a second view of the user interface according to Fig. 13; and

[0128] Figure 16: A flowchart of an embodiment of a method for applying actinic radiation to a living being. Figure 1 shows an embodiment of a body irradiation device 1.

[0129] This has an exposure tunnel 17 in which a user can lie down to be irradiated with actinic radiation.

[0130] Preferably, the exposure tunnel 17 is closed by essentially pivoting an upper part 18 of the body irradiation device 1 towards a lower part 19 of the body irradiation device 1 after the user has entered the exposure tunnel 17.

[0131] The lower part 19 of the body irradiation device 1 has an at least substantially transparent surface 35, beneath which irradiation modules 2 are arranged in two housings 33. Irradiation modules 2 are also arranged on the upper part 18.

[0132] In the embodiment shown in Fig. 1, the lower part 19 further comprises a housing 33 with additional irradiation modules 2, which are arranged above the transparent surface 35. The actual pivotable upper part 18 in this case has only two housings 33 with irradiation modules 2, since a joint 36 for pivoting the upper part 18 is arranged between the two front housings 33 in Fig. 1 and the rear housing 33 above the transparent surface 35. The transparent surface 35, which is preferably formed by a glass or acrylic plate, is supported by two frame parts 37a, 37b.

[0133] In the longitudinal direction of the exposure tunnel 17, a plurality of irradiation modules 2 are preferably arranged in a housing 33 of the irradiation modules 2, each of which can preferably be controlled separately. This allows different body regions of the user, for example, the head, torso, shoulders, legs, front, and back, to be irradiated with different radiation spectra and / or radiation intensities or temporal radiation profiles.

[0134] Alternatively, a single irradiation module 2 can be arranged in a housing 33. In this case, individual LED radiation sources 4, 5 or circuits 6A, 6B, 7, each with several LED radiation sources 4, 5, are controlled separately.

[0135] Preferably, the body irradiation device 1 comprises a control means 25, which serves at least to control the LED radiation sources 4, 5, 11, 29 (not shown). This control means 25 is preferably designed as a software-implemented controller, which is executed in a computing unit of the body irradiation device 1, or as a standalone control unit.

[0136] The irradiation modules 2 preferably have air-permeable areas in the end faces 34a, 34b. Air can be drawn in through these end faces 34a, 34b to cool the LED radiation sources in the irradiation modules 2 and the electronics required to operate the LED radiation sources 4, 5, 11, 29 (not shown). This air is expelled through openings in the central region of the housings 33.

[0137] Figure 2 shows a first embodiment of an irradiation module 2.

[0138] First LED radiation sources 4 and second LED radiation sources 5 are arranged on a circuit board 3. The first LED radiation sources 4 are electrically connected in series by two circuits 6A, 6B. Circuit 6A connects the LED radiation sources 4 of the left-hand part of circuit board 3 in Figure 2, and circuit 6B connects the first UV-A radiation sources of the left-hand part of circuit board 3 in Figure 2. Both circuits 6A, 6B can be contacted separately via their respective contacts 8, 9 and can therefore also be controlled separately.

[0139] By splitting the UV-A radiation sources into two circuits 6a, 6b, the total operating voltage to be applied can be halved. If UV-A LED chips 5 with an operating voltage of 3.7 V are used, the total operating voltage for operating circuit 6a, which connects the UV-A LED radiation sources, can be limited to 66.6 V.

[0140] Furthermore, the irradiation module 2 has a further circuit 7, which electrically connects the second LED radiation sources, which emit UV-B radiation, in a series circuit. This further circuit 7 crosses both circuit 6A and circuit 6B on the circuit board 3. Bridges 23 are arranged at the intersection points to route the further circuit 7 across circuits 6A, 6B.

[0141] Furthermore, the circuit board 3 has a predetermined breaking point in the central area of ​​Figure 2. This predetermined breaking point is also bridged by the additional circuit 7 with bridges 23. As can be seen from Figure 2, the first LED radiation sources 4, which emit UV-A radiation, are arranged in rows and columns. The second LED radiation sources 5, which emit UV-B radiation, are also arranged in rows and columns, offset from the first LED radiation sources 4.

[0142] The further circuit 7 can also be contacted separately via another contact 10 and thus controlled.

[0143] By arranging the UV-B LEDs 5 in the spaces between the UV-A LEDs 4, particularly homogeneous irradiation with both types of radiation can be ensured. On the one hand, a uniform irradiation intensity is ensured over an irradiation area, for example, in the exposure tunnel 17, and on the other hand, a comparatively large area can be irradiated with the irradiation module 2.

[0144] If this is advantageous in an application, a single, correspondingly large, irradiation module 2 can preferably be used to irradiate an exposure tunnel 17 over its entire length.

[0145] Figure 3 shows a second embodiment of an irradiation module 2. This is essentially identical to the embodiment of Figure 2.

[0146] In contrast to the first embodiment shown in Figure 2, however, the circuit board 3 has third LED radiation sources 11 that emit red or infrared light. These are also electrically connected in series via a separate circuit 12.

[0147] Preferably, two circuits 12 are provided in the left part and in the right part according to Figure 3. These circuits also preferably have separate contacts (not shown).

[0148] Figure 4 shows a third embodiment of an irradiation module 2. In this third embodiment, the circuit board, on the side on which the LED chips or irradiation sources 4, 5, 11 are arranged, is spanned by a glass plate 15, which is satin-finished on the side facing away from the circuit board 3. Furthermore, rings 20 are engraved into the glass plate 15. Each of the concentric ring arrangements 20 preferably covers one of the UV-A LED chips 4. Further concentric rings 24 preferably cover the UV-B LED chips 5.

[0149] In contrast to the first and second embodiments, the third embodiment includes only eight UV-B LED chips 5. If UV-B LED chips 5 with an operating voltage of 5.5 V are used, the total operating voltage for operating the circuit 7, which connects the UV-B LED radiation sources, can be limited to 44 V. Of course, the number of UV-B LED radiation sources can be reduced accordingly in the first and second embodiments.

[0150] Figure 5 shows a side view of the third embodiment according to Figure 4.

[0151] As can be seen from Figure 5, the glass plate 15 is held at a distance from the circuit board 3 by fastening means (in Figure 5 by screws). The element 22 in Figure 5 is a heat sink. A further plastic plate 16 is preferably arranged between the glass plate 15 and the circuit board 3, which further preferably adjoins the glass plate 15. This plastic plate 16 is preferably fluorescent and has, in an area covering the LED chips or LED radiation sources 4, 5, 11, preferably circular cutouts through which radiation emitted by the LED chips 4, 5, 11 can impinge unhindered on the glass plate 15.

[0152] Such a plastic plate 16 is shown in Figure 6.

[0153] Figure 7 shows a rear view of the irradiation module 2. Cooling fins 42 of the cooling element 22 are visible.

[0154] Figure 8 shows a second embodiment of a body irradiation device 1.

[0155] This exemplary embodiment of the body irradiation device 1 also has an upper part 18 and a lower part 19, which can be pivoted relative to the lower part 19 in the region of the joint 36. Two irradiation modules 2 are attached to a pivot arm 40 of the upper part 18. Furthermore, the upper part 18 has a first display 26a towards the front of the body irradiation device 1 and a second display 26b in the region of an end face of the body irradiation device 1. The lower part 19 of the body irradiation device 1 also has irradiation modules 2. One of these irradiation modules 2 is arranged in a lateral region of the body irradiation device 1 above a transparent surface 35 of the lower part 19, on which a user lies in the longitudinal direction of the body irradiation device 1 during intended use of the body irradiation device 1. Two further irradiation modules 2 are arranged below the transparent surface.The irradiation modules 2 are each held on support arms 41a, 41b. The support arm 41b additionally supports the upper part 18 of the body irradiation device 1 via the joint 36. Furthermore, the lower part 19 has a base 39, which is connected to the support arm 41a, 41b. The transparent surface 35, which is preferably formed by a glass or acrylic plate, is supported relative to the base 39 by two frame parts 37a, 37b.

[0156] A comfort fan 38a is attached to at least one of the frame parts 37a, 37b (frame part 37a in Figure 8), which cools the user with an air jet during normal operation. However, the comfort fan 38a can also be attached to another element of the body irradiation device 1. As shown in Figure 8, the comfort fan 38a is preferably designed as a type of bracket, which has a recess in the frame part 37a. Air is blown out, preferably via slots in the bracket, essentially in the longitudinal direction of the body irradiation device 1, so that a primary air flow is generated in the direction of the transparent surface or essentially parallel to it. This primary air flow preferably generates a secondary air flow, which flows through the recess. The primary air flow cools the user together with the secondary air flow, so that good cooling performance is achieved.Furthermore, the recess creates a sense of open space. This allows a user to feel less cramped inside the body irradiation device 1. Such a comfort fan 38a could also be attached to the body irradiation device 1 according to the first embodiment shown in Figure 1 or to another type of body irradiation device 1 within the meaning of this disclosure.

[0157] The body irradiation device 1 preferably has a control means 25, which serves at least to control the LED radiation sources 4, 5, 11, 29. This control means 25 is preferably designed as a software-implemented controller, which is executed in a computing unit of the body irradiation device 1, or as a standalone control unit. This computing unit 25 or the control unit 25 is preferably arranged in the base 39 of the lower part 19 of the body irradiation device 1, as shown in Fig. 8.

[0158] In addition, in a head region of the body irradiation device 1, at least one further comfort fan 38b is preferably provided in the irradiation modules 2 arranged above the transparent surface 35.

[0159] The irradiation modules 2 have a housing 33 which is delimited on a side facing the transparent surface 35 by a transparent plate 15 from which the radiation emitted by the respective irradiation sources (not shown) can emerge.

[0160] Furthermore, the irradiation modules 2 preferably have air-permeable areas in the end faces 34a, 34b. Air can be drawn in through these end faces 34a, 34b to cool the radiation sources in the irradiation modules 2 and the electronics required to operate the radiation sources. This air is extracted via openings in the respective housings 33 through air ducts in the pivoting arm 40 and in the support arms 41a, 41b into the lower part of the body irradiation device 1, in particular into its base 39, by means of a fan (not shown) installed there.

[0161] Using the displays 26a, 26b, which are designed as user interfaces, a user can adjust the operating settings for the body irradiation device 1. These displays are therefore preferably designed as touch-sensitive screens.

[0162] Figure 9 shows a plan view of the circuit boards 3a 3b of a fourth embodiment of the irradiation module 2.

[0163] These circuit boards 3a, 3b, equipped with LED radiation sources 4, 5, 29, in particular LED chips, are arranged inside the housing 33 of the irradiation modules 2 and, as explained further below, are preferably covered by a plate 15, in particular a glass or acrylic plate, which, during intended use, serves as a lying surface for a user. Further radiation sources 11, in particular third LED radiation sources, which are preferably designed in the form of LED light strips, are arranged on the longitudinally extending edge of the area delimited by the larger circuit boards 3a. As can be seen from Figure 9, the first circuit boards 3a and the second circuit boards 3b preferably have a kind of butterfly shape, with two halves of the circuit boards 3a, 3b preferably being axially symmetrical to a central axis.As can be seen from Figure 9, the contours of the first circuit boards 3a and the second circuit boards 3b preferably complement each other in such a way that they can be arranged adjacent to each other in the longitudinal direction of an irradiation module 2.

[0164] First LED radiation sources 5 are arranged on the first circuit boards 3a, which preferably have a larger area than the second circuit boards 3b. The arrangement of the first LED radiation sources 5 on the first circuit boards 3a preferably forms sectors of concentric rings. The second LED radiation sources 5 and fourth LED radiation sources 29 arranged on the second circuit boards 3b are preferably arranged in such a way that they essentially complement the sectors of the concentric rings formed by the first LED radiation sources 4. In addition, further second LED radiation sources 5 and fourth LED radiation sources 29 are arranged along the mirror axis of the second circuit boards 3b. The second LED radiation sources 5 and the fourth LED radiation sources 29 are preferably arranged in pairs on the second circuit boards 3b, in particular adjacent to one another.

[0165] In the fourth embodiment of the irradiation module 2 shown in Figure 9, the irradiation module 2 has ten first circuit boards 3a and nine second circuit boards 3b.

[0166] The two circuit boards 3a arranged in a section 32a in which the face of a user is arranged during intended use of the body irradiation device 1 preferably have more first LED radiation sources 4 than the first circuit boards 3a in the second section 32b. The second circuit board 3b arranged in the first section 32a also has more second LED radiation sources 5 than the second circuit boards 3b arranged in the second section 32b shown.

[0167] In the fourth embodiment shown in Figure 9, the first circuit boards 3a in the first section 32a each have 49 first LED radiation sources 4, and the second circuit board 3b has 16 second LED radiation sources 5 and 16 fourth LED radiation sources 29. In the second section 32b, the first circuit boards 3a each have 39 first LED radiation sources 4, and the second circuit boards 3b each have 12 second LED radiation sources 5 and twelve fourth LED radiation sources 29.

[0168] Preferably, the first LED radiation sources 4 emit UV-A radiation, and the second LED radiation sources 5 emit UV-B radiation. This means that preferably the substantial part of the radiation spectrum emitted by the first LED radiation sources 4 lies in the UV-A radiation range, and the substantial part of the radiation spectrum emitted by the second LED radiation sources 5 lies in the UV-B spectrum. The third LED radiation sources 11 preferably emit red and / or infrared radiation. The fourth radiation sources 29 preferably emit radiation in the visible spectrum, in particular in the yellow spectrum.

[0169] Preferably, the first LED radiation sources 4 and the second LED radiation sources 5 have a radiation angle of approximately 45°, i.e., an angle of twice approximately 22.5° to the surface normal. shows an enlarged view of an area A from Figure 9.

[0170] As can be seen in Figure 10, the first circuit board 3a and the second circuit board 3b preferably engage with each other. In particular, the first circuit board 3a has first regions 30 that engage with second regions 31 of the second circuit board 3b.

[0171] In the area of ​​the first areas 30, first LED radiation sources 4 are preferably arranged, and in the area of ​​the second areas 31, second LED radiation sources 5 are preferably arranged, in particular in pairs with fourth LED radiation sources 29. By overlapping the first areas 30 and the second areas 31 and by the first LED radiation sources 4 and second LED radiation sources 5 arranged in these areas 30, 31, a comparatively homogeneous irradiation intensity of UV-A radiation and UV-B radiation can be achieved in the longitudinal direction of the irradiation modules 2, even though the adjacent first circuit boards 3a and second circuit boards 3b arranged in this direction each exclusively contain first LED radiation sources 4, which emit UV-A radiation, and second LED radiation sources 5, which emit UV-B radiation.Furthermore, sections of two third LED radiation sources 11 are visible in Figure 10, which, as already explained above, are preferably formed by LED light strips.

[0172] Figure 11 shows a cross-sectional view of an irradiation module 2 according to the fourth embodiment. The cross-sectional view represents a cross section at the level of a first circuit board 3a.

[0173] The circuit board 3a is preferably attached to the housing by means of fastening means (no reference symbol). The same applies to the third LED radiation sources 11, which are preferably supported by another circuit board (no reference symbol). The first LED radiation sources 4 on the circuit board 3a are preferably covered by a plate 15, in particular a transparent glass or acrylic plate. This plate 15 is also supported on the housing 33 of the irradiation module 2 by means of fastening means (no reference symbol).

[0174] A cooling element 22 is preferably arranged on the rear side of the circuit board 3a, opposite the plate 15. On the rear side of the cooling element 22, a power supply 43 for the first LED radiation sources 4 of the first circuit board 3a is arranged on a further fastening element (no reference numeral).

[0175] Due to the comparatively large air space in the irradiation module 2, all elements can be effectively cooled by air. As already described with reference to Figure 8, this air is preferably drawn into the irradiation modules 2 via the end faces 34a, 34b (not shown) and then evacuated through an opening in the irradiation modules 2.

[0176] Figure 12 shows an enlarged view of area B from Figure 11.

[0177] As can be seen from Figure 12, the cooling element 22 preferably has cooling fins 42 in order to achieve better cooling performance.

[0178] The plate 15 is preferably satin-finished on one side, preferably on the side facing away from the first plate 3a.

[0179] Furthermore, a distance between the plate 15 and the surface of the circuit board is between approximately 20 mm and approximately 30 mm, preferably between approximately 15 mm and approximately 10 mm, most preferably approximately 13 mm. This makes it possible to achieve a particularly good scattering effect of the radiation emitted by the first LED radiation sources and second LED radiation sources, so that a particularly homogeneous radiation distribution on the surface of the user's body to be irradiated can be achieved. shows a view of the first user interface 26a. Preferably, the second user interface 26b, which is shown in Figure 8, can also be designed identically.

[0180] Preferably, the user interfaces 26a, 26b are designed as touch-sensitive screens. However, any other type of user interface is also conceivable, allowing user input.

[0181] As shown in Figure 13, the user interface 26a has a first controller 44, by means of which various irradiation profiles 28a, 28b, 28c can be set within an irradiation scenario 27a, which is preferably also displayed further down on the user interface 26a. Further preferably, the respective irradiation scenario 27a, 27b, 27c, 27d, 27e can also be selected by touching the respective graphic representing the irradiation scenario.

[0182] In the right-hand area of ​​the user interface 26a, a setting mask of a stereo system, which is preferably integrated into the irradiation device 1, can also be selected; in the left-hand area of ​​the user interface 26a, a setting mask of the comfort fan 38a, 38b (not shown) as well as the setting mask of the irradiation shown can be selected.

[0183] Each irradiation scenario 27a, 27b, 27c, 27d, 27e preferably has at least two irradiation profiles 28a, 28b, 28c. These irradiation profiles 28a, 28b, 28c are preferably selected from the following group of irradiation profiles: morning-intensive, morning-medium, morning-sensitive; midday-intensive, midday-medium, midday-sensitive; evening-intensive, evening-medium, evening-sensitive. The aforementioned irradiation profiles 28a, 28b, 28c are defined in the table below, with 100% UV-A radiation and 100% UV-B radiation at least substantially achieving the maximum permissible erythema-effective radiation intensity of UV radiation. The maximum permissible erythema-effective radiation intensity can be a statutory value or can be individually determined, for example, by an operator of the respective body irradiation device 1.

[0184] Furthermore, the irradiation profiles from the above-mentioned group can be defined according to the following table, where visible radiation means radiation in the visible range, particularly in the red spectrum, and / or infrared spectrum. 100%

[0185] Radiation corresponds to a predefined value.

[0186] Additionally, by selecting an irradiation scenario 27a, 27b, 27c, 27d, 27e, an offset value can be defined that changes the radiation intensity for the respective irradiation profiles 28a, 28b, 28c across the entire emission spectrum. This allows, for example, time-of-day-dependent irradiation profiles typical for different regions of the world to be selected.

[0187] Preferably, the irradiation profiles 28a, 28b, 28c are not only discretely selectable, but they can be continuously changed between a maximum value of the irradiation, which preferably represents the irradiation profile 28b, and minimum values ​​of the irradiation intensities, as represented by the irradiation profiles 28a and 28c.

[0188] This type of irradiation intensity control is illustrated in the schematic diagram of the function of the user interface 26a in Figure 14. The control 44a can be moved along a curved line between the discrete morning intensive irradiation scenario on the left side 28a, through midday intensive at 28b, to the discrete evening intensive scenario 28c. Depending on the position of the control 44a, the UV-A and UV-B irradiation then changes according to the curve shown further down in Figure 14.

[0189] In this way, a continuous stepless adjustment of the irradiation scenario 27a, 27b, 27c, 27d, 27e between the two discrete extreme scenarios morning intensive and evening intensive is possible.

[0190] Preferably, a lighting mood is generated via the third LED radiation sources 11 and / or the fourth LED radiation sources 29, which corresponds to the respectively selected irradiation scenario.

[0191] Furthermore, the mood or atmosphere of a treatment with actinic radiation can be preferably adjusted using the irradiation scenarios 27a, 27b, 27c, 27d, 27e and irradiation profiles 28a, 28b, 28c. Possible parameters include: temperature in the treatment room, light color in the treatment room, background noise in the treatment room, odor in the treatment room, misting in the treatment room, ventilation in the treatment room, and / or the addition of warming infrared radiation to the UV radiation.

[0192] The irradiation scenario 27a, 27b, 27c, 27d, 27e preferably generally specifies which parameters are activated and which value ranges are possible for the parameters. The irradiation profiles 28a, 28b, 28c then preferably define specific values ​​or temporal value profiles for the parameters.

[0193] Figure 15 shows a second view of the first user interface 26a As already described in

[0194] As explained with reference to Figure 13, this view could also be displayed on the user interface 26b.

[0195] In contrast to the first view in Figure 13, this view has a second controller 44b with which the irradiation intensity can be adjusted in the section 32b of the irradiation modules 2, in which the body of a user is located during intended use.

[0196] Furthermore, a third controller 44c can preferably be used to adjust the radiation intensity in the section 32a of the irradiation modules 2, in which the user's face is located during intended use. This allows the two sections 32a, 32b to be controlled independently of one another.

[0197] As in the view according to Figure 13, in Figure 15 in the left and right areas of the user interface 26a selection options for selecting other masks of the control are displayed.

[0198] Figure 16 shows an embodiment of a, in particular non-therapeutic,

[0199] Method 100 for applying actinic radiation to a living being.

[0200] Preferably, a body irradiation device 1 is used, as described with reference to the preceding figures and embodiments.

[0201] Preferably, a body irradiation device 1 is used, as described with reference to the preceding figures and embodiments.

[0202] The radiation intensity emitted by the first LED radiation sources 4 and the radiation intensity emitted by the second LED radiation sources 5 can be individually adjusted. In particular, the first LED radiation sources 4 of the first circuit board 3a are connected to one another via a first circuit, and the second LED radiation sources 5 and fourth LED radiation sources 29 of the second circuit board are connected to one another via a further circuit. These circuits are preferably supplied separately by separate power supplies. Preferably, each individual circuit board 3a, 3b is supplied by a separate power supply. Alternatively, groups of first circuit boards 3a and groups of second circuit boards 3b, or their respective circuits, can also be supplied by a single power supply 43.

[0203] In a first step 101a of the method 100, a selection of a radiation intensity to be emitted and / or a radiation dose of UV-A radiation to be emitted is preferably recorded. Simultaneously or independently, a selection of a radiation intensity to be emitted and / or a radiation dose of UV-B radiation to be emitted is preferably recorded. The respective selection is preferably recorded via a user interface 26a, 26b, which is further advantageously designed as a touch-sensitive screen. Controllers 44a, 44b, 44c are provided on such a touch-sensitive screen 26a, 26b, which allow the respective UV-A radiation and the respective UV-B radiation to be emitted to be set jointly or individually.

[0204] In addition, it is preferably detected whether different radiation intensities and / or radiation doses are to be emitted in different sections 32a, 32b of the body irradiation device 1. This can also be done via corresponding controllers 44a; 44b, 44c of a user interface 26a, 26b.

[0205] User inputs are recorded via a user interface 26a, 26b.

[0206] Preferably, the radiation intensity and / or the radiation dose of UV-A and UV-B radiation to be emitted is selected depending on a maximum permissible erythema-effective radiation intensity, and this maximum permissible erythema-effective radiation intensity is stored in the control means 25, in particular the control unit 25 via the computer-implemented controller. The erythema-effective radiation or power is preferably specified in power per square meter [W / m²] and takes into account the erythema effectiveness of the respective radiation type. The term erythema effectiveness refers to the ability of ultraviolet radiation to cause sunburn in the skin after certain threshold values, such as the erythema threshold dose or the threshold irradiation duration, are exceeded.Due to the dependence of the skin's erythema sensitivity on dose and wavelength, the erythema efficacy of a UV radiation source is determined by its spectral distribution and its radiation intensity. For example, UV-B radiation has a higher erythema efficacy than UV-A radiation. Regarding these photobiological effects, reference is also made to the standards IEC 60335-2-27 and DIN EN 60335-2-27.

[0207] In an alternative embodiment, in a first sub-step 101b-1, at least one irradiation scenario 27a, 27b, 27c, 27d, 27e is made available for selection, particularly via a user interface 26a, 26b. These irradiation scenarios 27a, 27b, 27c, 27d, 27e also define a maximum permissible erythema-effective radiation intensity.

[0208] Furthermore, each irradiation scenario 27a, 27b, 27, 27d, 27e preferably comprises a plurality of irradiation profiles 28a, 28b, 28c. The irradiation profiles 28a, 28b, 28c each define a radiation intensity to be emitted and / or a radiation dose of UV-A radiation and UV-B radiation to be emitted depending on the maximum permissible erythema-effective radiation intensity of UV radiation.

[0209] Different irradiation profiles 28a, 28b, and 28c thus determine different intensities of irradiation of a user in the body irradiation device 1. Furthermore, the irradiation profiles 28a, 28b, and 28c can also be used to determine the radiation doses of UV-A and UV-B radiation to be emitted. Temporal profiles of the UV-A and UV-B radiation can also be specified.

[0210] If third LED radiation sources 11 and / or fourth LED radiation sources 29 are present, the radiation intensity to be emitted therefrom as well as temporal profiles of the radiation intensity and a total radiation dose to be emitted with respect to these third radiation sources 11 and / or these fourth LED radiation sources 29, in particular to red and / or infrared radiation and / or radiation in the visible spectrum, can be determined by the irradiation profiles 28a, 28b, 28c.

[0211] This allows a wide variety of irradiation variants to be realized using an irradiation scenario 27a, 27b, 27c, 27d, 27e in conjunction with the irradiation profiles 28a, 28b, 28c, which, in terms of the irradiation types and moods, evoke or reproduce different geographical locations. Thus, it is possible (as shown, for example, in Figure 13) to store irradiation scenarios such as the Bahamas, Paris, Berlin, the Côte d'Azur, and the Canary Islands in the control means 25, each of which can be selected by a user. Preferably, the actinic radiation emitted then mimics these locations, as does the mood or atmosphere.

[0212] In a second sub-step 101 b-2, a selection of a user of the respective irradiation scenario from the several irradiation scenarios 27a, 27b, 27c, 27d, 27e is recorded.

[0213] This selection is also preferably recorded via the user interface 26a, 26b. Based on the selection of the irradiation scenario 27a, 27b, 27c, 27d, 27e, several irradiation profiles 28a, 28b, 28c are provided to the user for selection, preferably also via the user interface 26a, 26b.

[0214] In a third sub-step 101 b-3, a selection of the respective irradiation profile from the plurality of irradiation profiles 28a, 28b, 28c is then recorded.

[0215] Accordingly, the body irradiation device 1 preferably has the functions and corresponding means that allow the user to select such scenarios. For example, it is conceivable that a specific geographical location on Earth is specified, along with the time of day whose irradiation is to be simulated, for example, Malibu, June, midday, or Mallorca, August, afternoon.

[0216] For this purpose, the body irradiation device 1 preferably has a location determining means, for example a GPS module, in order to determine its location and to control the irradiation according to this geographical location.

[0217] In a second step 102, physiological parameters of the user, in particular pigmentation and / or a skin reaction to a radiation dose, are preferably measured. The respective emitted radiation intensity of the LED radiation sources 4, 5 can then be varied depending on the at least one physiological parameter.

[0218] Alternatively or additionally, in the second step, an actually emitted radiation intensity, in particular a radiation intensity of UV-A radiation and / or UV-B radiation, can also be measured and the radiation intensity can be varied depending on the actual radiation intensities.

[0219] In a third step 103, the LED radiation sources are controlled such that a specific radiation intensity, in particular in a time-dependent pattern, and / or a specific radiation dose is emitted within a predefined period of time. In particular, UV-A radiation, UV-B radiation, and / or red and / or infrared radiation from the respective first 4, second 5, and third LED radiation sources 11 can be emitted in a controlled manner in this way. Preferably, the radiation intensity of the LED chips or LED radiation sources 4 that emit UV-A radiation and / or the radiation intensity of the LED chips or LED radiation sources 5 that emit UV-B radiation can be varied over time.

[0220] In particular, circuits 6a, 6b, 7, which connect the first LED radiation sources 4, the second LED radiation sources 5 and the third LED radiation sources 11 to one another, are controlled in such a way that the radiation intensity of the respective LED radiation sources 4, 5, 11 varies over time.

[0221] The determined temporal irradiation profiles 28a, 28b, 28c and / or the determined radiation dose can be determined based on the measurement of the at least one physiological parameter performed in the second work step 102. Furthermore, the determined temporal irradiation profiles 28a, 28b, 28c and / or the determined radiation dose can be determined in advance based on further criteria.

[0222] The second LED radiation sources 5 are further controlled in such a way that they are operated with less than 70%, preferably less than 60%, most preferably with approximately 50% of the rated current or the rated power of the second LED radiation sources 5.

[0223] Furthermore, the first LED radiation sources 4 and the second LED radiation sources 5 are preferably controlled in different sections 32a, 32b in the longitudinal direction of the body irradiation device 1 in such a way that different radiation intensities and / or radiation doses are emitted in the different sections 32a, 32b.

[0224] The ability to vary different types of radiation, in particular UV-A radiation, UV-B radiation, and red or IR radiation, independently of one another over time using the body irradiation device 1 and the method 100 allows various scenarios of natural irradiation, in particular solar irradiation, to be simulated. It should be noted that the exemplary embodiments are merely examples that are not intended to limit the scope of protection, application, or design in any way. Rather, the preceding description provides the person skilled in the art with a guide for implementing at least one exemplary embodiment, wherein various modifications, in particular with regard to the function and arrangement of the described components, can be made without departing from the scope of protection as it results from the claims and combinations of features equivalent to these.
