Description

IRRADIATION DEVICE AND IRRADIATION METHOD Technical field The present invention relates to an irradiation device. In particular, the present invention relates to a device that allows irradiating radiation to be directed at a subject, for example, the entire body of a person, or more specifically, at those parts of a person's body that are not exposed at all, or are exposed only to a lesser extent, to such radiation by conventional irradiation devices. Non-restrictive examples of such parts of a human being that are not the object of radiation by conventional irradiation devices are the scalp, shoulders, the areas between the arms and upper body, and the areas between the legs. Without limiting the invention, this specification illustrates irradiation devices that direct irradiating radiation to the shoulders of a subject, such as a person.The present invention also relates to a non-therapeutic method for delivering radiation to parts of the body that are not normally irradiated. Description of the prior art. Devices and methods for irradiating a subject with radiation, for example, the body of a human being, are known to the state of the art and are used in practice for various purposes. Human body tanning, that is, the activation of melanin production and the conversion of melanin into the dark (brown) form of the pigment that occurs naturally in human skin, is achieved by irradiating the skin of a subject with radiation having a wavelength λ in the range of 280 to 315 nm (UV-B radiation) and / or radiation with a wavelength of 315 to 400 nm (UV-A radiation). Tanning can have cosmetic and / or medical applications. The number of applications is constantly increasing. Furthermore, radiation with wavelengths in the visible and near-infrared (IR) range (from 400 nm, or better from > 550 nm to 850 nm), when irradiated on human skin, is capable of activating the synthesis of compounds beneficial for the nutrition, rejuvenation, and regeneration of human skin, for example, collagen, elastin, keratin, and hyaluronic acid, as known from, for example, EP 2 500 060 A1, and from US document 2012 / 150.265 A1 and document WO 2010 / 070.277 A1. Devices capable of irradiating UV-B, UV-A, red visible and near-infrared vision to the whole or part of a subject's body, for example, a person, during a phototherapy session have beneficial effects for the user standing on a user protection wall that transmits vertical surrounding light (for example, acrylic) from the device, or lying on a user stand that transmits light (for example, acrylic) from the device that has UV-B, UV-A and / or red visible and infrared light-emitting light sources mounted outside the user protection or under the user stand.These latter devices may also have an articulated, connected canopy containing additional UV-B, UV-A and / or red and infrared visible light sources mounted on a light-transmitting protective layer, thus allowing the light sources to radiate UV-B, UV-A and / or red and infrared visible light to the front and rear sides of the subject / user. Document DE 102 33 984 A1 relates to a solarium comprising two semi-cylinder-shaped units forming an irradiation tunnel and equipped with UV lamps and optionally HPA lamps for tanning a user's face. The solarium can be used in either vertical or horizontal positions. Document DE 43 14 679 A1 relates to a device disclosed as suitable for improving insufficient shoulder tanning typically achieved in a tanning bed, and thus expected to produce a shoulder tan that more closely resembles a natural sun tan. The device has a reflector integrated into a head pillow, which provides uniform UV radiation to the entire skin area of ​​the user's shoulders by reflecting the UV light emitted by high-pressure UV light sources that tan the user's face. Alternatively, low- or high-pressure lamps arranged in the pillow can emit tanning UV radiation directed at the user's shoulders. One of the disadvantages noted by many users was that not all areas of the user's body would receive the same type or amount of radiation as other areas. Specifically, the user's scalp, shoulders, the areas between the user's arms and upper body, and the areas between the user's legs were not exposed. z / onnn / Lznz / e / YiAi This fact is illustrated by Figures 1A and 1B: User 200, standing inside (though not shown) the irradiation / exposure tunnel 110 of the irradiation device 100, may receive radiation (exemplified by the dashed arrows) from the light sources 170 on its front and rear sides, while certain parts of the user's body (shown: the scalp 207 and shoulders 210) can hardly be exposed to such radiation. Furthermore, a tanning device like the one disclosed in the aforementioned document DE 43 14 678 A1 makes the tanning bed structure more complex. The aforementioned disadvantages must be overcome. Therefore, it was an object of the present invention to provide an irradiation device and a non-therapeutic irradiation method that allow areas of the user's skin (such as, for example, the shoulders) to be irradiated with beneficial radiation. Document DE 87 01 889 U1 describes a device for applying actinic radiation directed at a subject, comprising an exposure tunnel that can surround the subject and has an interior space where the subject is exposed to actinic radiation, separate from an exterior space comprising a plurality of radiation sources. An additional exterior space, also separate from the interior space, is located at a longitudinal end of the exposure tunnel, comprising a plurality of additional radiation sources configured to emit actinic radiation toward the subject. The device further comprises a reflector configured as a mirror that reflects light from the additional radiation sources at an angle of approximately 45°.

An additional exterior space, also separate from the interior space, is located at a longitudinal end of the exposure tunnel, comprising a plurality of additional radiation sources configured to emit actinic radiation toward the subject. The device further comprises a reflector configured as a mirror behind the additional radiation sources to reflect the emitted light back into the exposure tunnel. Document DE 195 02 983 A1 describes a device for applying actinic radiation directed at a subject, comprising an exposure tunnel that can surround the subject and has an interior space where the subject is exposed to actinic radiation, separate from an exterior space comprising a plurality of radiation sources.

Document DE 196 40 118 A1 describes a device for applying actinic radiation directed at a subject, comprising an exposure tunnel that can surround the subject and having an inner space where said subject is exposed to actinic radiation separate from an outer space comprising a plurality of radiation sources, wherein an additional outer space separate from said inner space is located at a longitudinal end of the exposure tunnel, the additional outer space comprising a plurality of additional radiation sources configured to emit actinic radiation towards the subject. WO 2010 004 500 A1 describes a device for applying actinic radiation directed at a subject, comprising means for converting light emitted by radiation sources having a first wavelength into a different wavelength, wherein the different wavelength is in the visible wavelength spectrum. The different wavelength is also used to irradiate the subject. The conversion means can be a fluorescent color z / onnn / Lznz / e / YiAi or a combination of colors.

In other words; The terms comprise or comprise or comprising may have the meaning of describing a non-exhaustive enumeration of elements / steps or, alternatively, may have the meaning of describing an exhaustive enumeration of elements / steps, in the latter case without excluding other preferred embodiments characterized by additional features. Therefore, by means of the terms comprise, includes or comprising, a non-exhaustive enumeration and an exhaustive enumeration of elements or features or steps of the method is disclosed in this application and claimed in the appended claims. The features described herein in connection with the preferred embodiments may each be realized as a single feature or may be realized in combination with an additional feature, or together with some other features, or with several other features, or with all the features described herein and claimed in the claims. All such combinations of two or more features are covered by the present invention as claimed. Detailed description of the embodiments Reference is now made to Figures 2A to 2C, which show a preferred embodiment of a radiation application device 100 of the present invention. Such device 100 as shown in figures 2A to 2C serves for an application, to a subject 200, of directed actinic radiation. The term actinic radiation, as used in the specification and claims, is understood to mean light or radiation (more broadly) of the entire electromagnetic spectrum (see the definition given in Rompp Chemie-Lexikon, Thieme Publishers, Stuttgart, Germany), which has a photochemical effect (including a photobiochemical effect) and includes, as the case may be, light / radiation of natural or artificial origin. In the claims and specification, actinic light or actinic radiation primarily, but not restrictively, is used to mean light or radiation of artificial origin, for example, light / radiation emitted by light sources in a radiation application device 100 of the present invention.The term directed actinic radiation, as used in the descriptive memory and in the claims, has the meaning of actinic radiation that is irradiated with a preferred, if not more or less exclusive, focus on a target that is, according to the present invention, a subject, more preferably a human subject or a human user, i.e., a person 200. In a preferred embodiment of the device 100 of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, said actinic radiation may be broad-wavelength actinic radiation, the wavelength or wavelength range of which is not restricted in the present invention. Alternatively, although also preferred, said actinic radiation may be narrow-wavelength actinic radiation or even actinic radiation of a very specific wavelength or of several specific wavelengths. As is known to those skilled in the art, who may select the wavelength or wavelengths or wavelength ranges or bands to be applied according to the requirements of a specific case. Particular examples of actinic radiation having wavelengths usable within the scope of the present invention are: actinic radiation having a wavelength λ in the range of 280 to 315 nm (UV-B radiation) and / or actinic radiation having a wavelength λ in the range of 315 to 400 nm (UV-A radiation) for tanning the human body by activating melanin generation and converting melanin into the dark (brown) form of the pigment that occurs naturally in human skin, the tanning of which may have purposes in the wellness and / or cosmetic and / or medical fields; actinic radiation in the form of short-wavelength UV-B radiation in the wavelength range of λ = 297 nm±10 nm for promoting the biosynthesis of vitamin D from vitamin D precursors in human skin;or actinic radiation having wavelengths λ in the visible and near-infrared (IR) range (400 nm or, even better, > 550 nm, to 850 nm), which actinic radiation, when applied to human skin, is capable of activating the biosynthesis of compounds beneficial for skin nutrition, rejuvenation, and regeneration, such as collagen, elastin, keratin, and hyaluronic acid. These examples, however, should not be interpreted as a restriction of the invention. The term directed in combination with actinic radiation, as used in the descriptive memory and in the claims, is understood to mean actinic radiation that is emitted by a light source emitting actinic radiation and that has a direction originating from a light source and that reaches or impinges on a determined target, for example, a surface A (general) or a body surface (specific) of a subject / user 200. This is shown in Figures 1A and 1B for the prior art and in Figures 2A and 2B for the present invention. zyonnn / Lznz / e / YiAi As an example, Figures 2A, 2B, 4, and 5 show light sources with reflectors and actinic radiation emitters. Within the scope of the present invention, the target is preferably a subject, particularly a person. The directed radiation can be emitted from light sources equipped with shutters and / or reflectors and / or filters and / or other directing means or combinations thereof. The term actinic light-emitting light source, or simply light source, as used in the specification and claims, is understood to mean a medium that emits light / radiation of a specific wavelength or a more or less broad wavelength band. According to the invention, any such light-emitting medium may be designated as an actinic light-emitting light source. A person skilled in the art is familiar with a large number of different light sources within the scope of the foregoing definition.Illustrative embodiments of such actinic light-emitting light sources are low-pressure gas-discharge light-emitting lamps (or tubes) (also: low-pressure fluorescent lamps) or high-pressure light-emitting lamps (or radiators), which normally emit light in relatively broad wavelength bands, and of which several types are well known to a person skilled in the art and do not require further description herein. The term actinic light-emitting light source also includes LEDs, which normally emit light in very specific (and usually narrow) wavelength bands. All such actinic radiation-emitting light sources can be used in the present invention, as a person skilled in the art will readily learn from the following description and claims. The term "subject," as used in the specification and claims, is understood to mean any subject to which actinic radiation can be applied in a directed manner. A person skilled in the art knows various subjects (including apparatus) to which actinic radiation can be applied. In preferred embodiments of the invention, the subject is a person, and the terms "human," "person," and "subject" are used synonymously in this application. The terms application and apply and applying, as used in the descriptive memory and in the claims, are understood to mean, when combined with actinic radiation or (more generally) radiation, the step of irradiating actinic radiation from a light source that emits actinic radiation to a subject with the aim of exerting a certain photochemical or photobiochemical effect. z / onnn / Lznz / e / YiAi According to the present invention, the device 100 for an application of actinic radiation directed to a subject 200 comprises several elements which are explained in detail below. This radiation application device 100 may be a well-known device with respect to most of its elements and is described in detail in general and in its preferred embodiments, with reference to Figures 2A, 2B, 2C and 3, and in particular to Figures 2A, 2B and 2C, as follows; The device 100 for applying actinic radiation to a subject 200 comprises, as its central element, a so-called exposure tunnel 110. The term "exposure tunnel," as used in the description and claims, is understood to mean a tunnel-shaped space 110 in which a subject 200 can be received, i.e., the exposure tunnel 110 can surround said subject 200, and in which said subject 200, when received, can be exposed to directed actinic radiation. The size and shape of this exposure tunnel 110 are not restricted and can be selected by a person skilled in this regard according to the requirements of the specific case.In any case, the exposure tunnel 110 must have at least one size, i.e., a longitudinal length and a width and height perpendicular to the longitudinal length, so that the subject 200 can be generously surrounded by the exposure tunnel 100 to recline or stand comfortably in it. A person skilled in the art is familiar from the general art published in this technical field with the size and shape of an exposure tunnel 110 capable of surrounding a subject for the application of actinic radiation. In preferred embodiments of the invention (as in the prior art), the exposure tunnel may be of a suitable size to accommodate the subject in a convenient position (lying down, i.e., reclining, or standing, i.e., upright). Therefore, the size may be 200 to 220 cm in length and 90 to 120 cm in width / height around the subject, without restricting the invention to such a size. In other preferred embodiments of the invention (without restricting the invention), the shape of an exposure tunnel 110 is a cylinder (at least approximately). In a preferred embodiment of the radiation application device 100 of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, said exposure tunnel 110 has a longitudinal axis A-A, i.e., an axis identical to the axis of a cylindrical form, which is arranged horizontally, i.e., parallel to the ground on which the device 100 is placed when in operation. Devices 100 comprising said exposure tunnel 110' having the horizontally arranged axis are conventional exposure beds that receive the subject 200 in a reclining position. Most users of the device 100 rate this as very convenient and relaxing. Furthermore, actinic radiation can also be advantageously irradiated onto parts of the subject's / user's body according to the present invention that are not at all, or only to a lesser extent, the target of the radiation emitted by the radiation sources 170 of the device 100 of the invention. An example of such a device 100 is shown in Figures 2A, 2B, and 2C. As seen by way of example in Figure 2A, the device 100 comprises a first part 180 of a chassis and a second part 190 of a chassis, and the first part (in operation of the device 100: the upper part) 180 can be rotated away from the second part (in operation: the lower part) 190 along an axis parallel to the longitudinal axis A - A of the exposure tunnel 110, to allow the subject / person 200 to enter the device 100, i.e., the exposure bed within the exposure tunnel 110, in an easy and convenient manner. In a preferred alternative embodiment of the device 100 of the invention, the exposure tunnel 110 has a longitudinal axis, i.e., an axis identical to the axis of a cylindrical form, which is arranged vertically, i.e., perpendicular to the ground on which the device 100 is placed when in operation. Devices 100 comprising the exposure tunnel 110 with the vertically arranged axis are exposure booths that receive the subject 200 in an upright or standing position. Most users of the device 100 find this very dynamic while in motion. Furthermore, this device 100 obviously saves a considerable amount of space. Furthermore, actinic radiation can also be advantageously irradiated onto parts of the subject's / user's body according to the present invention that are not at all, or only to a lesser extent, the target of the radiation emitted by the radiation sources 170 of the prior art device 100, as shown in Figures 1A and 1B. An example of such a device 100 is shown in Figure 3.As shown for example in Figure 3, the device 100 comprises a first (or front) part 180 and a second (or rear) part 190 of a chassis, and the first part (in operation of the device 100; the front part) 180 can be turned outwards, in a manner similar to a door, from the second part (in operation: rear part) 190 along an axis parallel to the longitudinal axis A - A of the exposure tunnel, to allow the subject / person 200 to enter the device 100, i.e., the exposure booth within the exposure tunnel 110, in an easy and convenient manner. Depending on the type of device 100 (i.e., accommodating the subject in a reclining or upright position), said exposure tunnel 110 is formed by a first surface 120 in the form of a semicylindrical barrel and by at least one second surface 140, wherein said at least one second surface 140 is capable of complementing the first surface 120 in forming said exposure tunnel 110. This means that, in specific embodiments of the device 100 of the invention, an exposure tunnel 110 can be defined in shape and size by said first and second surfaces 120, 140 completely. In more preferred embodiments of the radiation application device 100 of the invention, which may be carried out separately or together with one or two or several or all of the other features of the invention, said exposure tunnel 110 is formed by said semicylindrical barrel-shaped surface 120 and by at least one substantially flat surface 142. Preferably, this is an embodiment of the device 100 that has the form of an exposure bed in which the subject can be exposed to direct clinical radiation in a reclining position: The subject 200 is placed on said substantially flat surface 142 which, in this embodiment, is in a horizontal orientation.In this embodiment, said semicylindrical cylinder-shaped surface 120 is disposed above said substantially flat surface 142, usually capable of moving away from said flat surface 142 by rotating said barrel-shaped semicylindrical surface 120 around an axis parallel to a lateral edge of said flat surface 142 to open the exposure tunnel 110 for easy entry of the subject 200 for clinical radiation exposure. The term "substantially flat" in relation to the surface 142 on which the subject rests, as used in the descriptive memorandum and in the claims, is understood to mean a surface that extends in a horizontal plane substantially without recesses or elevations. As is usual, however, in the present field of the art, this resting surface for which the subject 100 is exposed to actinic radiation may include recesses for placing the subject's head 205, back, arms 215, or legs 220, without substantially departing from the overall flatness. In similarly preferred alternative embodiments of the device 100 of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, the exposure tunnel 110 is formed by the semi-cylindrical barrel-shaped surface 120 and at least one other, or second, semi-cylindrical barrel-shaped surface 141. Preferably, this is an embodiment of the device 100 that has the form of an exposure booth within which the subject 200 can be exposed to directed actinic radiation in an upright position: The subject 200 is positioned between the two semi-cylindrical barrel-shaped surfaces 120, 141, which, in this embodiment, are arranged vertically. In this embodiment, the semi-cylindrical barrel-shaped surface 120 is arranged side-by-side with the second semi-cylindrical barrel-shaped surface 141 to form a complete cylinder.A portion of said cylinder is usually able to move away from said second barrel-shaped semicylindrical surface 141 by rotating said barrel-shaped semicylindrical surface 120 about at least one axis parallel to a vertical edge of said second barrel-shaped semicylindrical surface 141 to open the exposure tunnel 110 for easy entry of subject 200 for exposure to actinic radiation. Subject 200 stands substantially in the center of a cylindrical space formed by the two barrel-shaped semicylindrical surfaces 120, 141 and, when exposed to actinic radiation, optionally rotates about its own vertical axis. According to the invention, the first barrel-shaped semicylindrical surface 120, and also at least a second surface 140, are made of a material substantially permeable to said actinic radiation to be applied to the subject 200. The term material substantially permeable to said actinic radiation, as used herein and in the claims, is understood to mean that the material of the surfaces is of such a nature that at least that portion of the actinic radiation emitted by the light sources to have the desired photochemical or photobiochemical effect can pass through said surfaces without substantial amounts thereof being absorbed by the surface material.Furthermore, the selected material is required to have sufficient strength and stiffness to support the user lying on it. A person skilled in this technical field is familiar with such materials and can select them from among various materials according to the requirements of a specific case. In particularly preferred embodiments of the invention, surfaces 120 and 140 are made of a material selected from the group of light-permeable actinic polymeric materials, and acrylic polymers are particularly preferred, as in the prior art. In addition, other materials known in the prior art capable of allowing the passage of substantially all actinic radiation directed at them may be used alone or in combination. In an even more preferred embodiment of the invention, an additional surface 143, similar to the first barrel-shaped semicylindrical surface 120 and the at least one second surface 140, is also made of a material substantially permeable to said actinic radiation to be applied to the subject 200. According to the invention, the device 100 for an application of actinic radiation directed to a subject 200 has a shape such that the surfaces 120, 140 and, optionally, any additional surface 143, of the exposure tunnel 110 separate an inner space 130, where a subject 200 being exposed to actinic radiation is surrounded by said surfaces and exposed to said actinic radiation, from the outer spaces 150, 160 where light sources 170 capable of emitting actinic radiation through said surfaces 120, 140 are mounted such that said light sources can emit said actinic radiation through said surfaces 120, 140 towards the subject 200. Said outer spaces 150, 160 can have any shape that a person skilled in the art considers suitable for the purpose of, among other things, accommodating said light sources 170, without the invention being restricted in any way.In particular, the shape of such exterior spaces 150, 160 may depend on the type of device 100 used. In preferred embodiments of the device 100 of the invention, which may be carried out separately or together with one or two or several or all of the other features of the invention, if said exposure tunnel 110 has a longitudinal axis A - A arranged horizontally, as shown in Figures 2A, 2B and 2C, upper light sources 170u capable of emitting actinic radiation through said surface 120 downwards to the subject 200 placed in the reclining position on said substantially flat surface 142, and lower light sources 1701 capable of emitting actinic radiation through said surface 140, 141, 142 upwards to the subject 200 placed in the reclining position are mounted on said surface 120 in said outer space 150 and below said surface 140, 141, 142 in said outer space 160.In this embodiment, the exterior spaces 150, 160 are upper and lower spaces and are used, among other things, for housing said upper and lower light sources 170u, 1701. The exterior spaces 150, 160 can be used according to the invention for other purposes as well, which are described in more detail below. In alternative preferred embodiments of the device 100 of the invention, which may be carried out separately or together with one or two or several or all of the other features of the invention, if said exposure tunnel 110 has a longitudinal axis A - A arranged vertically (as shown in Figure 3), front-side light sources 170fs capable of emitting actinic radiation through said surface 120 backward to the subject 200 standing in an upright position in said inner space 130 surrounded by said surfaces 120, 140, and rear-side light sources 170bs capable of emitting actinic radiation through said surface 140 toward the standing subject 200 are mounted on the outer sides of said surfaces 120, 140 in said outer spaces 150, 160.In this alternative embodiment, the exterior spaces 150, 160 are front-side exterior spaces and rear-side exterior spaces, which are used, among other things, for the accommodation of said front and rear light sources 170fs, 170bs. The exterior spaces 150, 160 can be used according to the invention for other purposes as well, which are described in more detail below. According to the invention, said exterior spaces 150, 160 are housed in at least the first and second parts of a chassis 180, 190 of the device 100 and comprise means 181, 191 for securely fastening and electrically and electronically operating said light sources 170 and / or means 182, 192, providing said at least the first and second parts of the chassis 180, 190 and the components therein, for example, by emitting said light sources 170 actinic radiation to the subject 200, with electrical power and / or means 183, 193 capable of ventilating, heating and / or cooling the device 100; and means 184, 194 for further operation of the device 100, such as, for example, control means and / or at least one processing unit for controlling the operation of the device 100 and / or for enabling the connection of external control means.Other means known to a person skilled in similar devices of the prior art may also be fitted, individually or in combination, to the outer spaces 150, 160 of the first and second parts 180, 190 of the chassis, such as, for example, handles for opening and closing the moving parts of the chassis 180, emergency switches capable of stopping the operation of the device 100 in emergency situations, nozzles (and their operating channels and pumps) to allow access of fresh, cooling or heating air or liquid aerosols to the exposure tunnel 130, a central processing unit 194 capable of operating the device 100, actinic radiation sensors, a skin color / condition sensor for determining the condition of the subject's / user's skin as relevant to an actinic radiation exposure, to list only a few examples. In preferred embodiments of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, subject 200 is a person 200 who is exposed to said directed actinic radiation. Persons 200 who are exposed to said directed actinic radiation are sometimes also referred to in this specification as users of the device 100. As described in detail above, according to the present invention, the first and second parts of the chassis 180, 190 of the device 100 are capable of complementing each other by forming the external shape of the device 100 when moved closer together or further apart in an articulated manner. As shown by way of example in Figures 2A and 2C, the device 100 comprises a first part 180 and a second part 190 of a chassis, and the first part (in operation of the device 100: the upper part) 180 can be rotated away from the second part (in operation: the lower part) 190 along an axis parallel to the longitudinal axis A-A of the exposure tunnel 110, to allow entry into the device 100, i.e., into the exposure bed within the exposure tunnel 110, in an easy and convenient manner. According to the invention and as shown in Figures 2A and 2B, the device 100 further comprises at least one additional outer space 300 separated from said inner space 130 by neither of said first and second radiation-permeable surfaces 120, 140 and located at one or both longitudinal ends, i.e., the head-side end 111, in a longitudinal direction, of the exposure tunnel 110 and the foot-side end 112, in a longitudinal direction of the exposure tunnel 110. According to the invention, said at least one additional outer space 300 houses a plurality of additional radiation sources 310A, 310B capable of emitting radiation towards the subject 200 in a direction that forms an acute angle with the longitudinal direction of the device 100.There may be another exterior space 300, or there may be two (or even more, for example, three or four) other exterior spaces 300 located at one or two of the longitudinal ends 111, 112 of the exposure tunnel 110, suitable and configured to accommodate a plurality of additional radiation sources 310A, 310B and capable of emitting radiation towards the subject 200 in a direction that forms an acute angle with the longitudinal direction of the device 100. A person skilled in this field may make a selection of the number of additional exterior spaces 300 on the basis of the requirements of a single case. In preferred embodiments of the invention, which may be carried out separately or in conjunction with one, two, several, or all of the other features of the invention, said at least another outer space 300 is another outer space 300 located at the longitudinal end 111 of the head side of the exposure tunnel 110, said other outer space 300 housing a plurality of additional radiation sources 310A, 310B capable of emitting radiation towards, for example, and without restriction, the scalp 207 and shoulders 210 of the subject. This embodiment of the invention is considered particularly advantageous because the object of the invention can be easily achieved; areas of the user's body that are not the target of the irradiated light in conventional irradiation devices 100 can be irradiated as desired. In other preferred embodiments of the invention, which may be carried out separately or together with one or two or several or all of the other features of the invention, the device 100 of the invention may be able to radiate radiation of different types onto a user 300. In a preferred embodiment, the device 100 is a tanning device that emits tanning radiation onto a user 200, for example, radiation having an intensity suitable for tanning the user's body in the wavelength range of 280 to 315 nm (UV-B radiation) and / or radiation having a wavelength of 315 to 400 nm (UV-A radiation). Conventional tanning devices were not technically effective in tanning the user's shoulders 210 or scalp 207, for example, and a uniform tan on the user's skin could hardly be achieved. According to the present invention, even parts of the user's body that are not normally targeted by UV radiation (for example, the shoulders 210) can be reliably tanned, thus achieving a uniform tan of the user's entire body. In another preferred embodiment, the Device 100 is a device that radiates visible red light and / or near-infrared light of wavelengths in the range of 400 nm, or better than > 550 nm, to 850 nm onto the user's body, thereby activating the synthesis of compounds beneficial for the nutrition, rejuvenation, and regeneration of human skin, e.g., collagen, elastin, keratin, and hyaluronic acid. For these and other purposes, in preferred embodiments of the invention, which may be carried out separately or in conjunction with one, two, several, or all of the other features of the invention, the plurality of additional radiation sources 310A, 310B are selected from the group consisting of high-pressure lamps, medium-pressure lamps, low-pressure gas discharge lamps, LEDs, and combinations thereof. Even more preferably, the plurality of additional radiation sources 310A, 310B are selected from the group consisting of high-pressure lamps, LEDs, and combinations thereof. Although high-pressure or low-pressure lamps can be used, according to the invention, as individual radiation-emitting sources or as pairs of two or groups of three or more of the same in the device 100 of the present invention, the LEDs can preferably be used as a plurality of LEDs arranged in arrays of, for example, 20 or 30 or even fewer of the same or even more of the same, fixed and electrically connected and electronically controlled on a board. In other preferred embodiments of the invention, which can be carried out separately or together with one or two or several or all of the other features of the invention, for example, an irradiation device 100 suitable for tanning the user's body, various combinations of additional radiation-emitting sources 310A, 310B were developed and deemed suitable, without being limited to these preferred embodiments. Although the present invention proposes that, in order to direct tanning radiation to parts of the user's body which, when using tanning devices of the prior art, do not receive tanning radiation at all or receive only quantities of tanning radiation evaluated as insufficient for the desired tanning result, LEDs can be used as additional radiation sources 310A, 310B, a good tan of the shoulders, scalp, etc., can also be achieved, according to the present invention, by irradiating the subject's / user's shoulders (as an illustrative embodiment of the invention) or the scalp by means of low-pressure fluorescent lamps or high-pressure discharge temperatures or LEDs emitting radiation of the appropriate wavelength (range) alone or in every conceivable combination.Particularly suitable are combinations of LEDs with low-pressure fluorescent lamps or combinations of LEDs with high-pressure discharge lamps, all of which emit tanning UV radiation in the corresponding UV-A and UV-B ranges. Of course, a person skilled in the art is not restricted by the present invention to selecting radiation sources that emit such relevant UV-A and UV-B ranges according to the requirements of a single case. In further preferred embodiments, such ultraviolet radiation may also be combined with radiation in the visible and / or infrared (IR) wavelength ranges for specific purposes, as will be recognized by a person skilled in the art, without being subject to any restriction imposed by the present invention. In other words: In other preferred embodiments of the invention, which may be carried out separately or together with one or two or several or all of the other features of the invention, for example, an irradiation device 100 suitable for tanning the user's body, the usual low-pressure (fluorescent) lamps may be used as sources of light / actinic radiation 170. Furthermore, it is possible (as another preferred embodiment of the invention) that medium- or high-pressure (discharge) lamps (i.e., combined with low-pressure lamps) may also be used for specific purposes: As is known to those skilled in the art, in tanning devices such as the devices 100 of the present invention, high-pressure lamps (radiators) may be employed, for example, to tan specific parts of the user's body, for example, the user's face.In other preferred devices 100 of the invention, LEDs z / onnn / Lznz / e / YiAi emitting appropriate radiation of tanning light wavelengths may be used, either alone (i.e., instead of) or in combination with other light sources emitting radiation 170, for example, low-pressure (fluorescent) lamps and / or medium- or high-pressure (discharge) lamps. In particularly preferred embodiments of devices 100 of the invention, the light sources emitting luminous / actinic radiation 170 are low-pressure (fluorescent) lamps and / or high-pressure (discharge) lamps, and the additional light / radiation sources 310A and 310B are selected from combinations of LEDs and low-pressure lamps and / or high-pressure lamps and LEDs, or from LEDs exclusively.A skilled person may select suitable light / radiation sources 170 and / or 310A / 310B, and combinations thereof, from the devices 100 of the present invention on the basis of the requirements of a single case, without being subject to any restriction. In other preferred embodiments of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, the device 100 may be provided with other lamps / light sources to achieve a number of specific objectives, such as, for example, enhancing the tanning effect of tanning light sources and / or stimulating the synthesis of collagen, keratin, or other biochemically beneficial compounds. Such stimulation may preferably (without restriction) be initiated by emitting light / radiation onto the user's body or parts thereof in wavelength ranges from 400 nm (visible wavelengths) to 850 nm (near-infrared wavelengths) or in partial ranges thereof. The following table shows non-restrictive examples of LEDs that emit visible light / radiation at specific wavelengths: Table of non-restrictive examples of suitable LED wavelength ranges / intervals zyonnn / Lznz / e / YiAi Wavelength (range) [nm] Intended purpose 545-550 (540) Stimulation of PPIX (protoporphyrin IX) in photodynamic therapy (PDT) 585 - 590 (580) Stimulation of PPIX (protoporphyrin IX) in photodynamic therapy (PDT) Wavelength (range) [nm] Intended purpose 610-615 (613.5-623.5) Optimum compromise wavelength range between the H2O molecule stimulation wavelength (606 nm) and the lower cytochrome oxidase C stimulation wavelength (613.5 nm - 623.5 nm) (range 1) 635-640 Optimum compromise wavelength range between the PPIX (PDT) stimulation wavelength (635 nm) and the upper cytochrome oxidase C stimulation wavelength (613.5 nm - 623.5 nm) (range 1) 670-675 Cytochrome oxidase C stimulation (667.5 nm - 683.7 nm) (range 2) 750-755 Cytochrome oxidase C stimulation (750.7 nm 772.3 nm) (interval 3) 830 - 835 Stimulation of cytochrome C oxidase (812.5 nm 846.0 nm) (interval 4) z / onnn / Lznz / e / YiAi In other preferred embodiments of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, the device 100 may comprise other elements, for example, to improve the efficiency of the light emitted by the light sources 170 and / or 31OA / 310B. With reference to Figures 2A, 2B, 4, and 5, it is exemplified (without restricting the invention to such embodiments) that the sealed sources 170 and / or 31OA / 310B emitting actinic radiation according to the invention may be provided with shutters and / or reflectors and / or filters and / or other directing means or combinations thereof. Within the scope of the present invention, the target is preferably a subject, particularly a person.In particularly preferred embodiments of the invention, where LEDs are employed, for example, in the additional light-emitting radiation sources 310A and 310B of the invention, LED arrays comprising a larger number of LEDs (such as, but not limited to, 16 LEDs, 20 LEDs, 24 LEDs, or any other preferred number of LEDs), a reflector array may be provided. As is known to a person skilled in this technical field, the radiation emitted by each of the LEDs, each provided with a reflector, can be collimated, i.e., concentrated and directed to a relatively small, predetermined area on the target (hereinafter, on the user's body or parts thereof), thereby improving its effectiveness. In particularly preferred embodiments of the invention, at least one reflector, and even more preferably one reflector per LED, is used for the purpose of collimating the radiation emitted by said LEDs as additional light / radiation sources 310A, 310B.This is shown in Figures 4, 5, 6A and 6B. Similarly, light sources other than LEDs that emit tanning radiation suitable to the subject / user's body may be provided with suitable means, for example, reflectors, to collimate and / or concentrate the emitted radiation to the desired target, i.e., the object's / user's body, especially parts thereof, most preferably those parts that do not receive sufficient tanning radiation when using tanning devices of the prior art. In other preferred embodiments of the invention, which may be carried out separately or in conjunction with one, two, several, or all of the other features of the invention, the device 100 may comprise means for cooling the light sources 170 and / or the additional light sources 310a / 310b. As is known to a person skilled in the present field of art, a considerable portion of the energy emitted by the light sources 170 and / or the additional light sources 310a / 310b is emitted in the form of thermal radiation. High-pressure discharge lamps and LEDs generally emit thermal radiation in addition to the radiation at the UV, visible, and / or IR wavelengths for which they are designed.The emitted heat can be used beneficially to heat the air volume of the radiation tunnel (where the subject to be irradiated is reclining or standing) or at least a part of the irradiation device 100, for example (but without limitation), the light-transparent protective layer on which the subject / user to be irradiated reclines. On the other hand, it must be taken into account that the heat emitted by the light sources must be dissipated to avoid impairing the functions of the light source lamps and shortening their lifespan. The dissipation of the heat generated and emitted by the light sources can be achieved by means known to a person skilled in the prior art, and no restriction is imposed on a person skilled in the present invention in this respect. Therefore, a person skilled in the art may select suitable cooling means according to the circumstances of a single case. Although the cooling means for the radiation sources 170 of the invention—that is, for those located above / behind the first barrel-shaped semicylindrical surface 120 and emitting radiation to the face and abdomen of the subject / user, and for those located below / behind the second surface 140 (either below / behind the second barrel-shaped semicylindrical surface 141 or below / behind the second substantially flat surface 142)—can be selected without any restriction regarding the space available for their accommodation and mode of operation. Therefore, such cooling means can be ordinary fans blowing air against the radiation sources for cooling, or they can be ordinary cooling jackets using coolant fluids (including liquid coolant fluids) to dissipate excess heat.However, such conventional cooling means cannot be used when the space for housing the radiation sources is already restricted, as proposed as an alternative, for example, when using arrays of a plurality of LEDs, thus considerably confining the space for (additional) housing of the cooling means. Therefore, in other preferred embodiments of the invention, which may be implemented separately or in conjunction with one, two, several, or all of the other features of the invention, the device 100 may comprise a confined space cooling system 500 as a cooling means for dissipating the heat generated / emitted by the light source lamps and not required for any beneficial heating purpose.Even more preferred according to the invention, and optionally carried out separately or together with one or two or several or all of the other features of the invention, the device 100 of the invention may comprise a light apparatus cooling system 500 for a confined space with the aim of, and for the purpose of, cooling (and thus dissipating the heat generated by) the plurality of additional radiation sources 310A, 310B configured to emit radiation towards the scalp 207 and shoulders 210 of the subject / user.In this context, in this descriptive memorandum and in the claims, the terms narrow space or restricted space or confined space are used interchangeably or as synonyms and have the meaning that, due to the requirements imposed by the device or its components to be cooled, only an insufficiently narrow or restricted or confined space is available to accommodate the components to be cooled together with a cooling system that performs the cooling action.Due to insufficient space to accommodate the complete cooling apparatus in the vicinity of the components or devices to be cooled, the cooling system is divided into a heat absorption component that absorbs heat where it is generated and a heat dissipation component that dissipates heat at a distance from the heat generation area, and the heat is efficiently transported from the heat generation area to the heat dissipation area, without the need to expend additional energy for heat transport. In this specification and in the claims, the terms proximal and distal are terms used to indicate, for the space-constrained cooling system 500 used in conjunction with the invention, a short (proximal) and long (distal) distance between the component to be cooled (and the thermal interface 510 located in the vicinity of the component(s) to be cooled), on the one hand, and the remaining components of a heat pipe arrangement, on the other hand. A general cooling system for restricted / confined spaces that can be used as an element in, and in combination with, the radiation application device 100 of the present invention is disclosed in European patent application 18 18 45 13.2 entitled "Restricted space cooling system and its use" filed with the European Patent Office on July 19, 2018, which is referenced herein and shown as an example in Figure 7A. This confined space cooling system 500, which can be used in the device 100 of the invention as a confined space cooling system or as more than one (i.e., a plurality of two or three or even more) confined space cooling system(s), and is shown as a confined space cooling system 500 in Figure 7A, may comprise as its main components - at least one 510 thermal interface configured to absorb heat from heat discharge appliances that are in close proximity to the at least one 510 thermal interface; - at least one heating tube 520 configured to transfer heat from the proximal end of the heating tube 521 to the thermal interface 510 to the distal end of the heating tube 522 from the thermal interface 510; - at least one 530 heat exchanger or 530 heat sink configured to dissipate the heat released by the distal end of the heating tube 522; and optionally - at least one heat dissipation means 540 configured to force a heat absorption means 550 to absorb and dissipate the latent heat from the heat exchanger 530 to an environment. According to the proposal of the present invention, the aforementioned main components of a confined space cooling system 500 may be part of the confined space cooling system 500 as at least one of each of the components. In other embodiments of the invention, one or two or all of the components may be part of the confined space cooling system 500 as two or three or even more of the same.As an alternative to the invention described above, one of the components (for example, without restriction, the thermal interface 510) may be present as a thermal interface 510, while one of the other components (or even two or all of the other components of the space-constrained cooling system 500) may be present as two or three of the same, for example, two, three, or four heating tubes 520 and one, two, or three heat exchangers 530 and one (or two) heat dissipation means 540. A person skilled in the art may select and vary the number of each of the components of the space-constrained cooling system 500 of the invention according to the conditions, circumstances, and requirements of a single case. The thermal interface 510 of the confined space cooling system 500 shown in Figure 7A is not confined in any way, provided it is configured to absorb heat from any heat discharge device in close proximity to the at least one thermal interface 510. In the context of the device 100 of the present description and claims, close proximity is understood to mean that, for optimized heat conduction between a heat generating device 310A, 310B, i.e., an additional radiation source 310A, 310B, and the thermal interface 510 of the confined space cooling system 500 shown in Figure 7A, the bonding surfaces must be in intimate contact with each other.This requires that each of the surfaces be made of a material that has a high coefficient of thermal conductivity, preferably a metallic material, and the materials should ideally have a fine finish and should be flat or coplanar with each other. In cases of surface roughness and waviness discrepancies, it is advisable to use suitable interface materials and / or heat-conducting pads or a heat-conducting paste to achieve a perfect fit. Therefore, in preferred embodiments of the invention, and as shown in Figure 7A, the thermal interface 510, made of a material having a high thermal conductivity value, and particularly of suitable materials such as, for example, a metallic material like aluminum, copper, steel, and their alloys, for example, a steel sheet, is a flat plate adapted to fit with a heat discharge apparatus from which heat will be absorbed. In further preferred embodiments, which may be carried out with one, two, or all of the other features of the invention and which should not be construed as a restriction of the invention, the at least one thermal interface 510 of the space-constrained cooling system (lighting apparatus) is at least one backing plate 321 of a lighting apparatus accessory, which discharges heat due to its characteristic energy emission spectrum. It is even more preferred that the at least one thermal interface 510 be at least one backing plate 321 of an LED array accessory. LED arrays are known to accommodate a plurality of LEDs in a device, where the LEDs are very close together and not only emit light, generally of at least a relatively narrow wavelength band, but also emit a considerable amount of heat (depending on their operating mode).Due to the adjacent mounting of the LEDs in the array, the space available for a sufficient cooling system is limited. If the backing plate of the LED array device is used as at least a 510 thermal interface, the heat generated by the LEDs during operation can be dissipated from the array, thereby improving LED performance and significantly extending the durability and lifespan of the LED installation and operation. As shown in Figure 7A, the second component of the space-constrained cooling system 500 that can be used in the device 100 of the invention is at least one heating tube 520. The at least one heating tube 520 is, or one, two, three, or even more heating tubes 520, configured to transfer heat from the at least one thermal interface 510 to at least one heat exchanger 530 through the at least one heating tube 520, namely, from the end 521 of the heating tube near the thermal interface 510, which takes heat from any heat discharge apparatus, such as, for example, a light apparatus such as an LED array, to the distal end 522 of the heating tube at the thermal interface 510 by the action of a fluid enclosed in at least one inner volume of the heating tube.Upon receiving heat, at the proximal end 521 of the heating tube to the thermal interface 510 (i.e., the proximal end 521 of the heating tube) from the at least one thermal interface 510, the fluid in the liquid phase undergoes a phase transition to become vapor, said vapor being generated from the fluid as heat is induced from the at least one thermal interface 510. Said vapor moves within the at least one heating tube 520 downwards (with respect to the temperature differential ΔT within the at least one heating tube 520, even if such movement may be against the direction of gravity) to the distal end of the heating tube cooler than the at least one thermal interface 510, i.e., to the distal end 522 of the heating tube.At the distal end 522 of the heating tube, a phase transition of the fluid from the vapor phase to the liquid phase is carried out, i.e., by condensation of the vapor back into the liquid phase of the fluid, under release of latent heat at the distal end 522 of the heating tube to said at least one heat exchanger 530. The condensed liquid-phase fluid then returns to the proximal end 521 of the heating tube upwards (with respect to the temperature differential ΔT inside the at least one heating tube 520, even if such movement may be one with the direction of gravity) to the proximal end of the heated heating tube at the at least one thermal interface 510, i.e., to the proximal end 521 of the heating tube for another heat transfer cycle. In other words, the movement of the fluid, in neither the vapor nor the liquid phase, within the at least one internal volume of the heating tube does not require an external driving force other than that of an applied temperature differential ΔT from a thermal load.
