Description

[Technical Field]

[0001] The present invention relates to a body irradiation device for a human body, comprising a radiation source having a base and at least one first LED chip capable of emitting a radiation spectrum having a first radiation peak and at least one second LED chip capable of emitting a second radiation spectrum having a second radiation peak different from the first radiation peak. [Background technology]

[0002] It is known from practice that body irradiation devices for the human body are designed, in particular, as irradiation devices in the form of solariums with a reclining surface, or as standing tanning devices, or as infrared treatment beds in which the human body or parts of the human body are exposed to a radiation spectrum of a specific wavelength range to affect the well-being, health, or regeneration of the human body. Known body irradiation devices use partly low-pressure radiation tubes and partly high-pressure radiation tubes, which emit a wide radiation spectrum and may require the placement of filters to prevent harmful radiation from reaching the surface of the human body. A disadvantage of body irradiation devices with low-pressure or high-pressure tubes is that, in particular, the radiation intensity varies greatly across a wide radiation spectrum, so that precise administration of radiation and the application of desired, particularly preferred radiation peaks cannot be achieved or involves high radiation losses. In particular, combination treatments in which specific radiation peaks are applied to the body in combination are largely random and can hardly be influenced in terms of their relative intensities.

[0003] In practice, body irradiation devices have been proposed in which in each case one LED chip is placed under the lens and emits a relatively narrow radiation spectrum with a relatively defined radiation peak, the difficulty here being to apply homogeneous radiation of different wavelengths to the human body so that uniform application across the entire surface of the human body is achieved.

[0004] EP 2800605 describes a body irradiation device for supporting vitamin D formation. It specifies different light sources, including multiple LEDs, capable of emitting a radiation spectrum. The light sources are placed within a reflector designed as a concave mirror, and the radiation emitted by the light sources is collimated by the reflector before passing through a filter layer that allows radiation of a predetermined bandwidth to pass. A drawback of this method is the impossibility of uniform irradiation due to the defined alignment of several peaks in the radiation spectrum. A further drawback is the large installation space required. Furthermore, the extinction of certain wavelengths by the filter layer leaves some of the energy unused.

[0005] US Patent No. 20050065579 discloses a body illumination device that allows radiation, particularly infrared radiation, to be irradiated onto a human body or part of the human body. The device is designed as a manually operated device and includes a circuit board. A lighting arrangement is connected to the circuit board via conductor tracks and includes one or more replaceable light-emitting elements, particularly LEDs. The lighting arrangement essentially represents a radiation source having a base and including LEDs, and thus the chips of each replaceable light-emitting element. The LED chips can emit a radiation spectrum with a radiation peak. Further light-emitting elements are arranged within the lighting arrangement, each of which also has a radiation peak and whose radiation spectrum is different from the radiation spectrum of the first LED chip. The entire lighting arrangement is covered by a lens 102, which is not an optical lens but constitutes a transparent cover.

[0006] The specification of US Patent No. 20200001105 shows a body irradiation device designed as a tanning device, which is designed to irradiate radiation of a specifically specified wavelength onto a human body or a part of a human body, and is provided with a radiation source having a plurality of LEDs, the LEDs can emit different radiation spectra, and the appearance design and structural arrangement of the LEDs are designed conventionally.

[0007] U.S. Patent No. 20120043907 describes an illumination device for illuminating plants, comprising a radiation source having a base for at least one first LED chip and a second LED chip. The first LED chip, unlike the second LED chip, emits a radiation spectrum greater than 400 nm in the visible spectrum, specifically, for example, red and blue, thereby providing distinct broadband radiation peaks. The first and second LED chips are arranged under a common lens within an LED package and can be controlled separately. Because the illumination device provides long-term illumination at a correspondingly low intensity over a relatively long interval compared to plants, it is not designed or suitable for illuminating the human body or parts of the human body. Bringing the illumination device too close to the target creates shadow areas.

[0008] U.S. Patent No. 20150097200 describes an illumination device for producing, in particular, visible light using a combination of LEDs and fluorescent materials, which has been found to produce a correspondingly broad and relatively uniform radiation spectrum. The illumination device has a base on which a first LED chip, a second LED chip, a third LED chip, and a fourth LED chip are arranged, each of which can be designed to produce different radiation spectra. The LED chips are arranged under a common lens within an LED package, and the LED chips can be controlled separately. The first radiation peak generated by the first LED chip is between 430 nm and 455 nm or 479 nm, the second radiation peak generated by the second LED chip is between 456 nm and 469 nm or 600 nm and 650 nm, and the first radiation peak generated by the third LED chip is between 600 nm and 650 nm in a first alternative. In this case, the fluorescent or excitable material emits radiation having a radiation peak between 500 nm and 555 nm, and the radiation of the LED and the radiation of the fluorescent material overlap. Use of the LED alone without the fluorescent material is not provided. The illumination device is used, for example, as a table lamp, and is not used to irradiate the human body. A method for manufacturing the illumination device is also described. Summary of the Invention

[0009] The object of the present invention is to specify a body irradiation device that can combine the radiation spectra of two or more LED chips and apply them uniformly to the human body.

[0010] This object is achieved according to the invention by a body irradiation device having the features of the independent claims.

[0011] According to one aspect of the present invention, a body irradiation device is provided, comprising a base and a radiation source having at least one first LED chip capable of emitting a first radiation spectrum having a first radiation peak and at least one second LED chip capable of emitting a second radiation spectrum having a second radiation peak different from the first radiation peak, the difference being that the first LED chip and the second LED chip are arranged in an LED package under a common lens and can be controlled separately. By arranging the first LED chip and the second LED chip under the common lens, radiation having the first radiation peak and radiation having the second radiation peak can be uniformly emitted through the common lens, preferably using a downstream collimation reflector for collimating the first radiation spectrum and the second radiation spectrum, so that a downstream area where a human body can lie is uniformly illuminated with the first radiation spectrum and the second radiation spectrum. This achieves a particularly homogeneous distribution of radiation. In particular, this prevents intensity peaks from reaching the human body. Furthermore, the ability to separately control the first and second LED chips allows for the radiation intensities of the first and second radiation spectra to be individually adjusted and regulated, thereby enabling simultaneous irradiation with the first and second radiation spectra as well as the ability to adjust the intensity peaks relative to one another for a desired result. Separate adjustment of the LED chips particularly preferably includes the possibility of individually adjusting the radiation intensities of different LED chips individually and independently of one another, thereby simultaneously setting a desired peak ratio that is effective in reducing energy consumption. Furthermore, the LED chips may also be individually contacted.

[0012] Here, the LED package is a housing that houses an LED chip. Therefore, it is actually an LED chip package. The LED package is not to be understood as meaning a housing that houses one or more LEDs, which themselves contain the LED chip housed in the LED package. The LED package includes contacts for contacting the individual LED chips. A lens covering the LED package seals off the LED chip housed in the LED package from the outside, so that the resulting LED can be used accordingly.

[0013] A body irradiation device is designed to irradiate the human body or a part of the human body, i.e., the body of an organism or individual, including all limbs and surface areas, with radiation that is particularly useful for cosmetic and hygienic reasons. As a result, it differs from irradiation devices that direct radiation at an object and do not have to observe health restrictions, for example, regarding dose and radiation spectrum. Therefore, in particular, individual or all limbs of a human or possibly another mammal can be considered as the body.

[0014] The radiation source preferably includes at least one third LED chip capable of emitting a third radiation spectrum having a third radiation peak different from the first and second radiation peaks, the third LED chip being disposed together with the at least one first LED chip and the at least one second LED chip under a common lens in an LED package and being separately controllable. As a result, the third radiation spectrum having the third radiation peak is preferably directed homogeneously and uniformly toward the human body, regardless of the intensities of the other two radiation peaks. Thus, it is also possible to irradiate the human body with three radiation spectra having three different radiation peaks, uniformly and with matching intensities. This makes it possible to perform complex combination therapies, in which the radiation spectra can be controlled simultaneously, overlappingly, and / or sequentially or in a pulsed manner, for example, to simultaneously address different aspects of body regeneration.

[0015] The radiation source preferably includes at least one fourth LED chip capable of emitting a fourth radiation spectrum having a fourth radiation peak different from the first, second, and third radiation peaks, and the fourth LED chip is disposed together with the at least one first, at least one second, and at least one third LED chip under a common lens in an LED package and can be controlled separately from them. The separate adjustment allows for individual control of all of the at least one first, second, third, and fourth LED chips, thereby enabling the setting of complex treatment patterns with alternating or interlaced activation radiation peaks.

[0016] The radiation source preferably includes at least one fifth LED chip capable of emitting a fifth radiation spectrum having a fifth radiation peak different from the first, second, third, and fourth radiation peaks, and the fifth LED chip is disposed in an LED package together with the at least one first, at least one second, at least one third, and at least one fourth LED chip under a common lens and can be controlled separately from them. The separate adjustment allows for individual control of all of the at least one first, second, third, fourth, and fifth LED chips, thereby enabling the setting of complex treatment patterns with alternating or interlaced activation radiation peaks.

[0017] Thus, a body irradiation device can also be used universally, since LED chips that are not used for the same radiation treatment but that allow different treatments to be performed in one device (combined device) can be placed under a common lens. Thus, for example, a body irradiation device can have, under the same lens, two LED chips used for the combined production of previtamin D3, and / or two or more LED chips used for tanning, and / or two or more LED chips used for skin and wound regeneration, and / or two or more LED chips used for the (cosmetic) treatment of acne, resulting in a multi-purpose device that is preferably therefore inexpensive to manufacture, purchase, and operate.

[0018] It is also possible to provide two or more first, second, etc. LED chips within the radiation source, for example, two LED chips with a first radiation peak and one LED chip with a second radiation peak. In another embodiment, for example, there may be one more first LED chip than second LED chip. In yet another embodiment, there may be one more second LED chip than third LED chip, resulting in a total of six LEDs in such an embodiment: three first LED chips, two second LED chips, and one third LED chip. Advantageously, six or fewer LED chips are arranged under a common lens, and similar types of LED chips can be controlled and contacted together.

[0019] Although the first radiation peak, the second radiation peak, etc., are different, this does not preclude the possibility of partial overlap of the associated radiation spectra, but the intensity and radiation density of the resulting overlap region are advantageously less than each of the individual radiation peaks.

[0020] In addition to the radiation source with the LED chip, the body irradiation device can also have further radiation generating means, such as for example a low-pressure tube or a high-pressure lamp.

[0021] It is possible to provide a universal base that can be equipped with different LED chips, with control depending on the LED chip provided.

[0022] The LED chip is advantageously placed on the base and covered by a lens forming a first primary lens. The lens can have a convex outer contour and a concave inner contour, like a focusing lens, and the lens diameter is at least three times, preferably at least four times, the largest diagonal of the LED chip. The distance that the lens lies within the projection from the LED chip, i.e., advantageously at least as large as the diagonal of the corresponding chip, ensures good distribution of the LED chip's radiation, even if the LED chip is not centrally located under the lens.

[0023] According to a preferred embodiment, a filter layer is arranged between the LED chip and the lens. The filter layer can be designed as a filter glass with short-pass and / or long-pass filters and is particularly useful for filtering out radiation with critical radiation wavelengths below and / or above a wavelength defined as a threshold. Such filter layers are advantageous for the broad radiation spectrum of high- and / or low-pressure lamps. For LED chips with correspondingly narrow radiation spectra, they can be omitted under certain circumstances. Filters are particularly advantageous for relatively small wavelengths and / or for peaks that are close to each other.

[0024] According to another preferred embodiment, the lens has an integrated filter mechanism that prevents unwanted radiation spectrums from passing through, thus filtering them out. The filter mechanism is advantageously a filter with a short-pass and / or long-pass filter that prevents radiation outside the desired spectrum from passing through, thus filtering it out.

[0025] However, an embodiment is preferred in which the radiation spectrum of the LED chip is limited so that no filter is required, which also advantageously results in a beneficial temperature evolution of the radiation source, since otherwise a filtered wave would cause an increase in temperature and therefore an increase in cooling effort and a decrease in efficiency.

[0026] When the radiation peak of an LED chip is defined by a wavelength, particularly beneficial irradiation results occur if the LED chip's spectrum is more than two-thirds, preferably more than three-quarters, and particularly preferably more than nine-tenths, within a bandwidth calculated by multiplying the wavelength (nm) by a coefficient F (i.e., wavelength x F), where F is selected to be between 1 + / - 0.005 and 1 + / - 0.05, thus surrounding the radiation peak on both sides. As a result, the radiation spectrum is substantially concentrated within a width of approximately equal size on both sides of the peak, thereby achieving particularly effective treatment of the human body with the defined radiation peak. At the same time, a very narrow deviation around the radiation peak ensures that only a small amount of harmful radiation is emitted. Particularly preferably, 99%, preferably 99.9%, and particularly preferably even 99.99% of the radiation is within the specified limits.

[0027] Preferably, the radiation peaks of the LED chips, i.e., for example, the first, second, third, fourth, and fifth LED chips, are selected from the group consisting of 290 nm + / - 2 nm, 297 nm + / - 2 nm, 310 nm + / - 5 nm, 365 nm + / - 10 nm, 620 nm + / - 15 nm, 660 nm + / - 15 nm, 465 nm + / - 20 nm, 740 nm + / - 20 nm, and 840 nm + / - 20 nm. In this case, specific wavelengths can be combined to form therapeutically and / or cosmetically beneficial combinations with consistent radiation intensities, thereby achieving physiological effects in the irradiated body. Selecting specific radiation peaks reduces exposure and thus reduces potential damage or stress to the human body from ineffective or suboptimal radiation, thus preventing physical injury. In each case, the tolerances given reflect the fact that the radiation peak of each LED chip cannot be reproduced exactly and always identically, but can vary within narrow limits.

[0028] The aforementioned radiation peaks belong to the group of cosmetically and hygienically useful radiation, regardless of any medical effects that may be present at the same time. In particular, cosmetically and hygienically useful radiation has a photobiological effect on the irradiated individual. Cosmetic and hygienically useful radiation strikes the individual's skin but, depending on the specific wavelength, can also penetrate deeper into the body. Effects include, for example, skin tanning, but additional physiological and psychological effects also result from irradiation. Cosmetic and hygienically useful radiation includes ultraviolet (UV) radiation outside the UV-C spectrum, visible (VIS) radiation, and near-infrared (nIR) radiation. In this case, UV radiation outside the UV-C spectrum has wavelengths between about 280 nm and about 380 nm, VIS radiation has wavelengths between about 380 nm and about 780 nm, and nIR radiation has wavelengths between about 780 nm and about 1400 nm. The specified spectra blend together. Depending on the cosmetic or hygienic application, irradiation can be focused on a subspectrum of the listed spectrum. For this purpose, the arrangements emitting cosmetically and hygienically useful radiation can also be dedicated to individual wavelengths, for example, UV radiation. It is understood that the above-specified preferred radiation peaks of the LED chips are all within the range of cosmetically and hygienically useful radiation. However, the list of specifically mentioned radiation peaks and / or any combinations of two or more radiation peaks of the LED chips expressly mentioned herein as part of this disclosure is not exhaustive.

[0029] Furthermore, an interesting aspect is that the combination therapy not only allows the human or animal body to be exposed to radiation of corresponding wavelengths, but also allows these radiation peaks to be correlated in a targeted manner, so that the intensity of the radiation can be adjusted relative to each other, as can the duration and / or sequence of irradiation.

[0030] Preferably, at least one radiation peak emitted by one of the LED chips, for example, the first LED chip or the additional LED chip, has a wavelength outside the visible light spectrum. In contrast to body irradiation devices that emit only broad-spectrum visible light, a body irradiation device is provided herein that also has at least one radiation peak with a wavelength within the ultraviolet (UV) radiation and / or near-infrared (nIR) radiation range outside the UV-C spectrum. The additional radiation peak may have a wavelength within and / or outside the visible (VIS) radiation spectrum. In this way, an irradiation mode that provides radiation in the invisible range can also be conveniently set.

[0031] Preferably, at least one radiation peak outside the visible light spectrum has a wavelength of less than 380 nm, and is therefore within the ultraviolet (UV) radiation spectrum outside the UV-C spectrum. It is possible to provide several radiation peaks from this spectrum. For example, the at least one radiation peak outside the visible light spectrum has a wavelength selected from the group including 290 nm + / - 2 nm, 297 nm + / - 2 nm, 310 nm + / - 5 nm, and 365 nm + / - 10 nm.

[0032] The at least one radiation peak outside the visible light spectrum may alternatively have a wavelength greater than 780 nm and thus lie within the near-infrared (nIR) radiation spectrum. Several radiation peaks may be provided from this spectrum. The at least one radiation peak outside the visible light spectrum may, for example, have a wavelength selected from the group including 840 nm + / - 20 nm.

[0033] The aforementioned radiation peaks outside the visible light spectrum can also be combined with further radiation peaks emitted by other LED chips and included within the visible light spectrum.

[0034] Preferably, a collimating reflector for collimating the radiation is placed downstream of the lens forming the primary lens. It uniformly collimates the radiation of all LED chips, thus forming a secondary lens. For this purpose, the collimating reflector is preferably designed as a truncated truncated cone or paraboloid of revolution with a highly reflective inner periphery, for example made of aluminum. As a result, the radiation exiting the lens is homogenized, and in particular, no relative intensity peaks occur within the irradiated surface area. It is particularly surprising that the same collimating reflector can be used for wavelength ranges that differ by up to two times, yet the emitted radiation still strikes the human body almost uniformly. To adjust the impact intensity, the LED chips can be controlled accordingly, which can be easily achieved by calibrating the body irradiator.

[0035] The collimating reflector advantageously has a small opening on the side facing the lens and a larger opening on the side facing away from the lens, which openings are advantageously circular. Radiation passing through the lens enters through the small opening, and collimated radiation exits through the large opening. The collimating reflector is therefore positioned completely upstream of the LED package and lens.

[0036] According to a beneficial embodiment, more than half of the LED chips are arranged eccentrically relative to the center point defined by the projection of the apex of the lens onto the base. Surprisingly, it has been found that at least two LED chips with uniform emission can be arranged on the base in a particularly beneficial manner if neither the first nor the second LED chip is arranged exactly on the center point, but in each case is arranged away from the center point. This initially results in less uniform illumination, which is almost completely compensated for by the downstream collimation reflector, while an arrangement of one of the LED chips on the center point would be less uniformized by the downstream collimation reflector.

[0037] Preferably, in the case of three or more LED chips, one of the LED chips is positioned on the center point defined by the projection of the apex of the lens onto the base, in which case a chip with a low radiation intensity and therefore high energy consumption when increasing the intensity is preferably selected.

[0038] However, advantageously, all LED chips are arranged eccentrically relative to a central point defined by the projection of the apex of the lens onto the base, so that uniform illumination, established in particular by the downstream collimation reflector, can be achieved for all LED chips and their respective radiation spectra.

[0039] According to a preferred embodiment, at least one of the LED chips is capable of emitting radiation in a pulsed manner. Pulsed radiation, preferably with a wavelength above 280 nm, preferably above 700 nm, can achieve beneficial effects, particularly in the treatment of the human body, and in this case, can be particularly stimulating. Pulsing of one LED chip can be provided simultaneously or alternately with pulsing of the other. Pulsed LED chips are advantageously used in the visible and near-infrared spectrum. However, it is also possible to pulse the LED chips in the UV-A and UV-B spectrum.

[0040] During pulsing of the LED chip, in a first preferred embodiment, the "pulse width ratio" parameter, i.e., the on / off ratio or the ratio of the duration of radiation emission to the duration of non-radiation emission, can be set within wide limits. In the first preferred embodiment, the on duration is equal to the off duration. In a second preferred embodiment, the on duration is 25% to 200% longer than the off duration. Surprisingly, by pulsing the LED chip with the above-mentioned pulse width ratio, a significantly better illumination effect than continuous illumination appears to be achieved.

[0041] During pulsation of the LED chip, the frequency parameter, i.e., the number of ON / OFF pulses per unit time, can be set within wide limits in a second preferred embodiment, which can be optionally implemented simultaneously with the first embodiment. Particularly effective frequencies are selected between 0.25 Hz and 500 Hz, preferably between 1 Hz and 100 Hz, particularly preferably between 8 Hz and 15 Hz, preferably 10 Hz. Further useful wave numbers lie above the frequencies perceived as intermittent by the human eye, i.e., in the frequency range above 50 Hz. Here, frequencies of 60 Hz, 120 Hz, and 240 Hz are considered, for example.

[0042] Separate pulsing of the first LED chip, the second LED chip, etc., independent of each other, may also be achieved by separate adjustment of the LED chips, although they may be coordinated with each other in some cases, and these additional features need not be provided in all embodiments.

[0043] Advantageously, multiple lenses are arranged on the carrier, each of which covers multiple LED chips in one LED package. According to a preferred development, all radiation sources thus formed on the carrier have the same design, so that each lens covers the same number of LED chips. However, the radiation sources provided in the illumination system can be designed in various ways.

[0044] According to a useful development, the body irradiation device further comprises a carrier on which a plurality of radiation sources are arranged under a common lens, each having a plurality of LED chips, whereby advantageously the same LED chips are uniformly controlled on the carrier.

[0045] A useful embodiment is that preferably 20 radiation sources or an integer multiple thereof are arranged on a carrier, so that the carrier can in each case be equipped with 20 radiation sources with multiple LED chips that can be arranged and operated modularly in the body irradiation device but can be easily replaced.

[0046] Preferably, the base of the radiation source is placed on the carrier in either case. The base can be, for example, integrally provided as a recess on the carrier, or can be glued, clamped, or placed on the carrier, for example, in a recess provided for this purpose. The base is preferably the foundation of the LED package, which further has an annular wall and thus forms a kind of chamber or receptacle. The underside of the base facing outward is preferably flat and can be fixed to the flat side of the carrier 41.

[0047] According to another preferred embodiment, all radiation sources on the carrier are designed identically so that the respective LED chips can be controlled together, in parallel, or in series. Thus, the first LED chips are operated together, the second LED chips are operated together, etc. Alternatively, the radiation sources on the carrier can be designed differently. In this case, the LED chips must be controlled individually. A combination of both embodiments is also possible, i.e., for example, an array of identically designed first radiation sources and, additionally, individual, differently designed second radiation sources.

[0048] The body irradiation device preferably has an irradiation space in which the irradiated human body is enclosed like a tunnel, and the tunnel can be designed as a vertically aligned tunnel with movable wall elements or as a bed with a pivotable cover element. The irradiation tunnel can be subjected to an air flow for heat dissipation, which cools the inside of the tunnel.

[0049] In this case, the body irradiation device preferably comprises a housing that at least partially encloses a tunnel-shaped irradiation space for the irradiated person and has at least one storage space for the light source. The partition of the housing between the storage space and the irradiation space is preferably made of a material that is transparent to the radiation of the radiation source. Here, the radiation of the radiation source is directed from the storage space to the irradiation space.

[0050] In one preferred embodiment, the first radiation peak is at 290 nm + / - 2 nm and the second radiation peak is at 297 nm + / - 2 nm. This combination within the UV-B spectrum allows for the convenient production of provitamin D3 while causing particularly low damage to the DNA of the treated individual.

[0051] Another preferred embodiment has a first radiation peak at 310 nm + / - 5 nm and a second radiation peak at 365 nm + / - 10 nm. Preferably, this combination of wavelengths from the UV-B spectrum and UV-A spectrum can achieve tanning of human skin by bleaching of pigments.

[0052] Another preferred embodiment has a first radiation peak at 620 nm + / - 15 nm and a second radiation peak at 660 nm + / - 15 nm. This combination of wavelengths from the visible (VIS) spectrum can achieve and / or promote cosmetic effects, skin rejuvenation, and / or wound healing.

[0053] In a preferred development, the third radiation peak is then 740 nm + / - 20 and the fourth radiation peak is 840 nm + / - 20 nm, thereby promoting and / or achieving wellness effects and regeneration of tendons, fascia and muscles.

[0054] In a further development, the fifth radiation peak is 465 nm + / - 20 nm, which also reduces acne on irradiated skin.

[0055] Yet another preferred embodiment has a first radiation peak of 465 nm + / - 20 nm, a second radiation peak of 660 nm + / - 20 nm and a third radiation peak of 840 nm + / - 20 nm, which preferably helps to soothe acne on the skin in particular.

[0056] According to one aspect of the present invention, the use of the body irradiation device described above is provided for cosmetic, medical, psychological, wellness and regenerative treatments. In particular, the body irradiation device can be provided for non-therapeutic treatment of the human and / or animal body, for example for psychological or cosmetic treatments.

[0057] According to one aspect of the present invention, there is provided a method for preferably non-therapeutic irradiation of a person with cosmetically and hygienically useful radiation, comprising a radiation source having a base and at least one first LED chip capable of emitting a radiation spectrum having a first radiation peak and at least one second LED chip capable of emitting a second radiation spectrum having a second radiation peak different from the first radiation peak, the method differing in that the first LED chip and the second LED chip are arranged under a common lens and controlled separately. As a result, it is preferably possible to match the intensities of the radiation spectra of the first LED chip and the second LED chip while ensuring that the radiation emitted by the radiation source uniformly hits the irradiated individual. The body irradiation device described above, including any further developments thereof, may be provided for this method. Preferably, third, fourth, and fifth LED chips, arranged under a common lens and controlled separately, are also possible, according to the above description. The method preferably achieves irradiation of the person's body or a part of the person's body. As a result, it differs from irradiation methods that direct radiation toward the subject and do not require observing health restrictions regarding dose and radiation spectrum. By housing several LED chips in one LED package, it is possible to place the body irradiation device close to the subject, while still achieving homogeneous administration with all radiation peaks within a small space. Because the body irradiation device is located close to the body, the radiation acts more intensively, and the duration of treatment is preferably shortened.

[0058] Further advantages, developments and characteristics of the invention will become apparent from the following description of preferred exemplary embodiments and the dependent claims.

[0059] The invention is explained in more detail below using preferred exemplary embodiments and with reference to the accompanying drawings. [Brief explanation of the drawings]

[0060] [Figure 1] 1 is a schematic side view of a preferred exemplary embodiment of a body irradiation device according to the present invention; [Figure 2] FIG. 2 is an exploded view of an irradiation module installed in the body irradiation device of FIG. 1. [Figure 3A] 3 is a cross-sectional view through a radiation source from the illumination module of FIG. 2. [Figure 3B] FIG. 3B is a plan view of the radiation source of FIG. 3A. [Figure 4A] 3 is a cross-sectional view of another radiation source from the illumination module of FIG. 2. [Figure 4B] FIG. 4B is a plan view of the radiation source of FIG. 4A. [Figure 5] 4 is a diagram showing the radiation intensity of two LED chips in the radiation source according to Example 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0061] 1 shows a body irradiation device 1 for irradiating a person, represented diagrammatically by a human body 10, with cosmetically and hygienically beneficial radiation, the device comprising a lower housing part 20 and an upper housing part 30 articulated to one another along an axis A. The upper housing part 30 can be pivoted upward to unobstruct access for the user 10, and downward so that the housing parts 20, 30 surround a tunnel-like tube 2 in which the user 10 lies.

[0062] The housing parts 20, 30 are enclosed in acrylic glass, and an acrylic glass lying surface 21 is formed in the lower housing part 20. The lying surface can be equipped with a silicone mat, which is connected to the lying surface 10 and is flexible, providing a comfortable surface feel for the person 10. The acrylic glass and the silicone mat are each transparent to at least some of the radiation that is cosmetically and hygienically useful.

[0063] The illumination modules 40, directed towards the tubes 2 in the housing parts 20, 30, are arranged in both the lower and upper housing parts 20, 30. The illumination modules 40 are rectangular and arranged adjacent to each other, parallel to the lying surface 21 in the lower housing part 20. Furthermore, an illumination module 40 capable of illuminating the individual 10 is also provided in the vertical part 22 of the lower housing part 20, which is approximately perpendicular to the lying surface 21. In the upper housing part 30, a plurality of illumination modules 40 are arranged in a row, in each case abutting each other, and the illumination modules arranged in a row are inclined at an angle to the adjacent rows so as to be able to follow the semicircular contour of the upper housing part 30 within the housing part 30. Depending on the radius and size of the illumination modules, the angle is between 5° and 25°, preferably about 10°.

[0064] A shoulder tanning device 50 is arranged at the front end of one of the tubes 2, which shoulder tanning device particularly irradiates the head and shoulders of the user 10, and two further irradiation modules 40 are arranged within the shoulder tanning device 50.

[0065] The illumination module 40 is connected to the controller S of the device 1 .

[0066] The body irradiation device 1 also includes a series of additional components to improve the irradiation experience. A touch-sensitive flat screen is provided inside the upper housing portion 30 as a first interface for communicating with the individual 10, allowing input from the individual 10 and also allowing playback of entertainment programs. Furthermore, a speaker is located within the head region of the individual 10, enabling an audio experience, such as background music, and possibly interacting with the visual entertainment program to enhance the irradiation experience. A second interface for communicating with the individual 10 is provided on the outside of the upper housing portion 30, through which programs can be selected. A voice control device is provided as a third interface for communicating with the individual 10, detecting voice input via a speaker attached to at least one of the housing portions, evaluating the voice input with computer assistance, and converting it into control commands for the body irradiation device 1. Furthermore, the body irradiation device 1 includes ventilation for the tube 2, which supplies fresh air and exhausts heated air from the tube. Furthermore, the body irradiating device 1 has a scenting device that allows it to scent the fresh air with one of several scents. Finally, the body irradiating device 1 also includes all the electrical and electronic components necessary for operation.

[0067] 2 shows an exploded view of the illumination module 40. It can be seen that a total of 20 radiation sources 50, each comprising at least one first LED chip 51 and one second LED chip 52 in contact with an electrical energy supply source via a carrier 41, are mounted in respective areas 41a of the carrier 41. It is also possible to provide a different number and / or arrangement of LED chips than those present in a 4x5 array arrangement.

[0068] In FIG. 2, it can be seen that one common lens 53 is shown on the carrier 41 for a total of six LEDs 51, 52, which lens is fixed to the surface 41a, has an outwardly curved shape and is transparent to the radiation of the LED chips 51, 52.

[0069] A structural unit 44 with 20 identically formed collimating reflectors 44a is provided upstream of the carrier 41 with the LEDs 42, 43, the size of the holes in the collimating reflectors 44a corresponding to the lenses 53. For this purpose, the reflectors 44a are connected in an area spaced apart from the LEDs 42, 43 with a disk 44b having openings for the collimating reflectors 44a so that the structural unit 44 can be handled as a part.

[0070] An annular disk 45 is arranged upstream of the structural unit 44, which has in its inner periphery a plate body coated with a fluorescent material, a number of circular recesses 45a corresponding to the number of collimation reflectors 44a. When the LEDs 51, 52 emit radiation, this radiation excites the fluorescent material of the ring 45a, and it can be seen that illumination of the ring 45a, which takes place in the visible range, causes the LEDs 51, 52 to also emit radiation.

[0071] The heat transfer plate 46 is arranged on the carrier 41 on the side opposite the LEDs 51, 52. The heat transfer plate is designed as a plate body and is intended to dissipate heat generated during operation of the LEDs 42, 43. For this purpose, the heat transfer plate 46 is connected via a first cooling line 47 and a second cooling line 47 to a heat sink 48 designed as a heat exchanger, with a circulating cooling fluid being supplied between the cavity-formed heat transfer plate 46, the first cooling line 47, the heat sink 48, and the second cooling line 47. Cooling of the heat transfer plate 46 can be achieved in particular by a phase transformation of the cooling fluid between the heat transfer plate 46 on the one hand and the heat sink 48 on the other hand.

[0072] The illumination modules 40 located within the housing portion 20 or the housing portion 30 are all constructed identically, however, it will be appreciated that the illumination modules may be constructed and / or controlled differently depending on the light sensitivity of particular body regions of the user 10.

[0073] A first sensor 61 is provided in the upper housing part 30, which determines the body characteristics of the user 10, in particular the height, width, circumference, and position of the arms and legs. The radiation intensity of the radiation module 40 is adjusted depending on the detected body characteristics. Thus, for example, the radiation module 40 facing away from the head end can be completely switched off when the user's legs no longer cover this radiation module 40.

[0074] Alternatively or additionally, the sensor 61 can detect certain skin characteristics of the user 10's body, such as the presence of tattoos, burns, wounds, moles, scars, white spots, pigmentation disorders, current sunburn, and skin type. This second sensor can also be designed as a camera, and an evaluation logic unit is connected to it, which detects the skin color and contrast at high resolution and evaluates the acquired images to determine the above-mentioned body characteristics. Then, depending on the skin characteristics, if there is a risk that the skin may burn during normal irradiation and exposure based on the detected skin characteristics, the illumination module 40 is operated at reduced power.

[0075] Finally, a second sensor 62 is arranged in the upper housing part 30 and detects the radiation of the illumination module 40 or the associated LEDs 51, 52. The second sensor 62 or its evaluation unit compares the detected radiation with target values, e.g. stored in the controller S, and depending on the deviation of the detected values ​​from the target values, the controller adjusts the operating parameters of the illumination module 40 so as to set them to the target values.

[0076] 3A and 3B show a cross-sectional view and a plan view of a first embodiment of the radiation source 50, which are not drawn to scale and which illustrate the structure of the radiation source 50. The radiation source 50 is housed in an LED package 60 made of an electrical insulator such as plastic or ceramic. The LED package has a rectangular, in this case square, layout and a base 61, the underside 61u of which can be connected, e.g., glued, to the surface of a carrier 41, such as a highly thermally conductive plate made of aluminum. Alternatively, the LED package 60 can be mounted in a socket attached to the carrier 41. Furthermore, electrical wiring is installed in the carrier 41. Typically, the carrier 41 has approximately 20 LED packages 60 arranged in a 5x4 array.

[0077] The first LED chip 51 and the second LED chip 52 are arranged eccentrically with respect to the center point of the base 61a on a base 61a opposite a substantially circular lower surface surrounded by a ring region 62. The two LED chips 51, 52 are contacted on the base 61a via corresponding conductor tracks 63. The electrical connections of the radiation source 50 are indicated at 64. The base 61a forms a recess, above which a filter layer 55 is arranged on an annular shoulder 62a of the annular region 62. The LED packages 60 form recesses that are open in only one direction, some of which may be arranged on the carrier 41.

[0078] The filter layer 55 filters the radiation emitted by the LED chips 51, 52 within predetermined wavelength limits, which may be pre-specified, for example, for health reasons. The lens 53 is supported and held circumferentially in a clamped state on an annular flange region 62b, which is positioned further outward from the base 61a. In addition, the lens can be glued to the annular flange region. It can be seen that a further base region is provided on the base 61a, on which further LED chips can be placed. It can be seen that only radiation filtered through the filter layer 55 can exit the lens 53.

[0079] 4A and 4B show a cross-sectional view and a plan view of another embodiment of a radiation source 50. In contrast to the embodiment according to FIGS. 3A and 3B, here a filter layer 55 is not provided. However, a filter mechanism 55a is integrated into the lens 53, which filters the radiation emitted by the LED chips 51, 52 within predetermined wavelength limits. It is possible to provide a combination of a filter layer 55 and a filter mechanism 55a in the radiation source 50. In another embodiment, no filtering of the radiation is performed.

[0080] Example 1 The radiation source 50 of the body irradiation device 1 includes a first LED chip 51 having a first radiation peak at 290 nm and a second LED chip 52 having a second radiation peak at 297 nm. The intensity ratio (level) of the first radiation peak to the second radiation peak is 1:5. This treatment helps to produce provitamin D3, and in this case, DNA damage to the irradiated body of the individual 10 is minimal.

[0081] 5 shows the intensity profiles of the first radiation spectrum of the first LED chip 51 and the second radiation spectrum of the second LED chip 52 with the above-mentioned radiation peaks in a diagram above the wavelength. The resulting curves are also shown.

[0082] Example 2 The radiation source 50 of the body irradiation device 1 includes a first LED chip 51 having a first radiation peak at 310 nm and a second LED chip 52 having a second radiation peak at 365 nm. The intensity ratio (level) of the first radiation peak to the second radiation peak is 3:1, but can be changed as desired. This treatment serves to stimulate pigmentation in the skin of the individual 10, also commonly referred to as tanning.

[0083] Example 3 The radiation source 50 of the body irradiation device 1 comprises a first LED chip 51 with a first radiation peak at 620 nm and a second LED chip 52 with a second radiation peak at 660 nm. The intensity ratio (level) of the first radiation peak to the second radiation peak is 2:1 and can be adjusted within wide limits. The treatment is useful for skin rejuvenation, wound healing, and cosmetic purposes.

[0084] Example 4 The radiation source 50 of the body irradiation device 1 comprises a first LED chip 51 having a first radiation peak at 465 nm, a second LED chip 52 having a second radiation peak at 660 nm, and a third LED chip (not shown) having a third radiation peak at 840 nm. The intensity ratio (level) of the first radiation peak to the second radiation peak to the third radiation peak is 1:2:1 and can be adjusted within wide limits. The treatment is useful for preventing and reducing acne on the skin of the person 10.

[0085] Example 5 The radiation source 50 of the body irradiation device 1 includes a first LED chip 51 having a first radiation peak at 620 nm, a second LED chip 52 having a second radiation peak at 660 nm, a third LED chip (not shown) having a third radiation peak at 740 nm, and a fourth LED chip (not shown) having a fourth radiation peak at 840 nm. The intensity ratio (level) of the first radiation peak to the second radiation peak to the third radiation peak to the fourth radiation peak is 2:1:1:2 and can be adjusted within wide limits. The treatment is useful for skin rejuvenation, wound healing, and cosmetic purposes, particularly for the regeneration of tendons, fascia, and muscles of a person 10.

[0086] Example 6 The radiation source 50 of the body irradiation device 1 includes a first LED chip 51 having a first radiation peak of 465 nm, a second LED chip 52 having a second radiation peak of 620 nm, a third LED chip (not shown) having a third radiation peak of 660 nm, a fourth LED chip (not shown) having a fourth radiation peak of 740 nm, and a fifth LED chip (not shown) having a fifth radiation peak of 840 nm. The intensity ratio (level) of the first radiation peak to the second radiation peak to the third radiation peak to the fourth radiation peak to the fifth radiation peak is 1:1:1:1:1 and can be adjusted within wide limits. The treatment is useful for skin rejuvenation, wound healing, and cosmetic purposes, especially for the regeneration of tendons, fascia, and muscles, as well as for the prevention and alleviation of acne on the skin of a person 10.

[0087] In all the examples given above, the illumination by one of the LED chips can be continuous and intermittent, for example in a pulsed manner, where the duration of the illumination is preferably twice as long as the pause between two successive illuminations.

[0088] The above example shows that targeted treatment of the body with radiation of a specific wavelength can achieve very favorable results. However, there is a risk of overdose if an individual wants to force a successful treatment. Therefore, in a preferred embodiment, at least one, and preferably both, of the two LED chips from Example 2 are additionally installed in the radiation source 50, thereby preventing misuse of the initiation of tanning.

[0089] From the above examples, it can be seen that a radiation source 50 having, for example, five dedicated LED chips can provide multiple illumination combinations, where not all of the LED chips are necessarily used, depending on the desired result. Thus, the radiation source 50 from Example 6 can also generate the illumination patterns of Examples 3, 4, and 5.

[0090] The LED chips are numbered above in each case according to increasing wavelength. It is understood that the assignment of some LED chips to first, second, etc. can be done in any desired way. For example, in Examples 4, 5, or 6, the 840 nm radiation peak, which is outside the visible spectrum, can be assigned to the first or second LED chip. In examples with two LED chips, the assignment to radiation peaks can be swapped, for example, so that the order is random.

[0091] The present invention has been described above with reference to exemplary embodiments in which the irradiance peak is selected from a group having a particular wavelength. It should be understood that additional LED chips having irradiance peaks at other wavelengths can easily be added to the group.

[0092] The present invention has been described above with reference to exemplary embodiments in which a filter layer 55 is provided between the LED chips 51, 52 and the lens 53, or the lens 53 has an integrated filter arrangement 56. It should be understood that in case of a narrow spectrum of radiation produced by the LED chip, the filter layer and / or filtering mechanism can be omitted. The same applies to LED chips whose radiation spectrum is in the visible or near-infrared range.

[0093] The present invention has been described above with reference to an exemplary embodiment in which only one LED chip having a particular radiation peak is provided in the radiation source, but it should be understood that two or more LED chips having a particular radiation peak may also be provided, regardless of further LED chips having other radiation peaks.

[0094] The present invention has been described above with reference to an exemplary embodiment in which the carrier 41 of the irradiation module 40 is generally rectangular and has a 4 x 5 array of radiation sources 50. It should be understood that the carrier 41 can also have a different shape, for example a square or hexagonal or rectilinear shape, and the radiation sources 50 can also be arranged differently on the carrier 41.

[0095] The present invention has been described above with reference to an exemplary embodiment in which a carrier 41 is connected to a heat exchanger plate 46 which is connected to a heat exchanger via a cooling line 47. It is to be understood that the heat exchanger 48 can simultaneously be connected to further carriers 41 via further cooling lines, and it is also possible to connect several heat exchanger plates to the heat exchanger 48 via connecting lines to form a closed system.

[0096] The present invention has been described above with reference to an exemplary embodiment in which all illumination modules 40 in the device 1 are designed identically. It is to be understood that the illumination modules 40 for the shoulder and head areas, the illumination modules in the lower housing part 20 and the illumination modules in the upper housing part 30 can also be designed differently and in particular can have different numbers of LEDs.

[0097] The present invention has been described above with reference to an exemplary embodiment in which the illumination module 40 is fixedly arranged within the housing parts 20, 30 and is controlled substantially in response to data acquired by the first sensor 61 and the second sensor 62. It will be appreciated that instead of being electrically controlled, the illumination module 40 may be adjustable with respect to its distance to the body of the user 10, for example via a pneumatic, hydraulic, mechanical or electrical adjustment device.

[0098] The present invention has been described above with reference to an exemplary embodiment in which the device 1 has a fixed lower part 20 and an upper housing part 30 that can be pivoted downward onto the lower part 20, with the user 10 resting on the lying surface 21 of the lower housing part 20. It should be understood that the device can also be designed in the form of a standing tanning device in which the two housing parts are arranged approximately vertically and the user essentially stands on the floor during irradiation and is surrounded by the housing parts. It should further be understood that the device can also be designed in the form of a vertical tanning device or tanning module, preferably arranged on a movable stand, which can be placed, for example, above a bed on which the user lies. Such an tanning device can be used, for example, to tan the face or another body part, or for other cosmetic and hygienic purposes.

[0099] The present invention has been described above with reference to exemplary embodiments in which sensors 61, 62 detect properties of the device 1 or the individual 10. It is understood that several sensors may be provided for this purpose and the data acquired by the sensors may be stored in order to record the appropriate adjustment of the device.

[0100] The present invention has been described above with reference to an exemplary embodiment in which the radiation sources 50 are combined with their bases 61 a to form the irradiation module 40. It should be understood that an irradiation module with several individual radiation sources 50 does not have to be on a common carrier, but each radiation source 50 can also be arranged on a separate carrier, which allows it to more easily follow, in particular, the curved shape of the upper housing part 30. The radiation sources 50 are then directly connected to the body irradiation device 1.
