Description

The invention relates to a body irradiation device for the human body, comprising an irradiation source with a base and at least one first LED chip that can emit a radiation spectrum with a first radiation peak and at least one second LED chip that has a second radiation spectrum with one of the first Radiation peak can emit different second radiation peak.

Body irradiation devices for the human body are known from practice, which are designed in particular as an irradiation device in the form of a solarium with a lying surface or a standing tanner or a red light treatment bed, in which the human body or parts of the human body are exposed to a radiation spectrum in certain wavelength ranges in order to to influence the well-being, the health or the regeneration of the human body. The known body irradiation devices here use partly low-pressure radiation tubes, partly high-pressure radiation tubes, which emit a broad spectrum of radiation, and in which it may be necessary to arrange a filter to prevent harmful radiation from reaching the surface of the human body. The disadvantage of body irradiation devices with low-pressure or high-pressure tubes is in particular that the radiation intensity fluctuates strongly across the broad spectrum of radiation, so that the correct dosage of radiation and exposure to the desired, particularly favorable radiation peaks is either not achieved or results in high radiation losses. In particular, combination treatments, in which certain radiation peaks are intended to act on the body in combination, occur at most randomly and their relative intensity can hardly be influenced.

In practice, body irradiation devices have been proposed in which an LED chip is arranged under a lens and emits a relatively narrow radiation spectrum with a comparatively defined radiation peak, the difficulty here being to subject the human body to uniform radiation of different wavelengths, so that a homogeneous exposure occurs over the entire surface of the human body.

EP 2 800 605 B1 describes body irradiation device to support the formation of vitamin D, in which various light sources, including a large number of LEDs, are specified that can emit a radiation spectrum, the light source being arranged in a reflector designed as a concave mirror and the radiation emitted by the light source through the reflector is collimated before it passes through a filter layer that allows a predetermined bandwidth of the radiation to pass. The disadvantage here is that uniform irradiation with a defined coordination of several peaks within the radiation spectrum is not possible. Another disadvantage is that a large installation space is required. Furthermore, the cancellation of certain wavelengths by the filter layer means that part of the energy remains unused.

It is the object of the invention to provide a body irradiation device with which the radiation spectrum of more than one LED chip can be combined and uniformly act on the human body.

According to the invention, this object is achieved by a body irradiation device having the features of independent claim 1.

According to one aspect of the invention, a body irradiation device is created, comprising an irradiation source with a base and with at least one first LED chip that can emit a first radiation spectrum with a first radiation peak, and with at least one second LED chip that has a second radiation spectrum can emit a second radiation peak different from the first radiation peak, which is further characterized in that the first LED chip and the second LED chip are arranged under a common lens in an LED housing and can be controlled separately. By arranging the first LED chip and the second LED chip under the common lens, radiation with the first radiation peak and radiation with the second radiation peak can be emitted evenly through the common lens - preferably with a downstream collimation reflector to collimate the first radiation spectrum and the second radiation spectrum - so that the downstream area in which 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 the radiation and in particular prevents intensity peaks from reaching the human body. Furthermore, by controlling the first LED chip and the second LED chip separately, the radiation intensity of the first radiation spectrum and the second radiation spectrum can be individually adjusted and regulated, so that not only the simultaneous irradiation with the first radiation spectrum and the second radiation spectrum is made possible, but also in addition, a coordination of the peaks in terms of intensity with respect to one another the desired result. The separate controllability of the LED chips particularly preferably includes the possibility of setting the intensity of the radiation of the various LED chips individually and independently of one another, whereby favorable peak ratios can be set which at the same time favorably reduce energy consumption. Furthermore, it can be provided that the LED chips can also be contacted separately.

The body irradiation device is designed to irradiate a human body of a person or a part of a human body of a person, ie the body of a living being or an individual, including all limbs and surface areas, in particular with cosmetically and hygienically useful radiation. In this way it differs from irradiation devices which direct radiation onto objects and in which no health restrictions need to be observed with regard to, for example, dose and radiation spectrum. Thus, in particular, individual or all limbs of a human person or possibly of another mammal can be viewed as a body.

The radiation source preferably comprises at least one third LED chip that can emit a third radiation spectrum with a third radiation peak different from the first radiation peak and the second radiation peak, the third LED chip with the at least one first LED chip and the at least one second LED chip is arranged under the common lens in an LED housing and can be controlled separately from these. This advantageously makes it possible to direct a third radiation spectrum with a third radiation peak onto the human body homogeneously and uniformly and independently of the intensity of the other two radiation peaks, and thus to use three radiation spectra with three different radiation peaks uniformly and in terms of intensity for irradiating the human body. In this way, in particular, complex combination treatments can be carried out in which, for example, the radiation spectra can be controlled simultaneously, overlapping and / or one after the other or in a pulsed manner, so that different aspects of body regeneration can be addressed simultaneously.

The radiation source preferably comprises at least one fourth LED chip which can emit a fourth radiation spectrum with a fourth radiation peak different from the first radiation peak and the second radiation peak and the third radiation peak, the fourth LED chip having the at least one first LED chip and the at least one second LED chip and the at least one third LED chip is arranged under the common lens in an LED housing and can be controlled separately from these. The separate controllability enables the individual control of all at least one first, second, third and fourth LED chips, so that complex treatment patterns with alternatively changing or combined activated radiation peaks can also be set.

The radiation source preferably comprises at least one fifth LED chip which can emit a fifth radiation spectrum with a fifth radiation peak different from the first radiation peak and the second radiation peak and the third radiation peak and the fourth radiation peak, the fifth LED chip having the at least one first LED chip and the at least one second LED chip and the at least one third LED chip and the at least one fourth LED chip is arranged under the common lens in an LED housing and can be controlled separately from these. The separate controllability enables the individual control of all at least one first, second, third, fourth and fifth LED chips, so that complex treatment patterns with alternatively changing or combined activated radiation peaks can also be set.

This also makes the body irradiation device versatile, since LED chips that are not used in the same radiation treatment can also be located under the common lens, but make it possible to carry out different treatments in one device (combination device). For example, a body irradiation device can have two LED chips that are used for a combined production of previtamin D3, and / or two or more LED chips that are used for tanning and / or two or more LED chips that are used for skin and wound regeneration can be used, and / or two or more LED chips, which are used for (cosmetic) acne treatment, under the same lens, which advantageously creates a multi-purpose device that is correspondingly inexpensive to manufacture Acquisition and is in operation.

It is also possible to provide more than a first, second, etc. LED chip within the irradiation source, for example two LED chips with a first radiation peak and one LED chip with a second radiation peak. In another embodiment it can be provided, for example, that one more of the first LED chip is provided than of the second LED chip. In yet another embodiment, it can then be provided that one more of the second LED chip is provided than of the third LED chip, so that in the execution as a whole Six LEDs are provided, three times the first LED chip, twice the second LED chip and once the third LED chip. Expediently, no more than six LED chips are arranged under a common lens, and similar LED chips can also be controlled and / or contacted together.

While the radiation peaks of the first, second, etc. radiation peaks differ, this does not exclude the possibility that the associated radiation spectra partially overlap. Appropriately, however, the resulting intensity and the radiation density of the overlap area is lower than each of the individual radiation peaks.

In addition to the radiation sources with LED chips, the body irradiation device can also have other radiation-generating means, for example low-pressure tubes or high-pressure emitters.

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

The LED chips are expediently arranged on the base and covered by the lens forming a first primary lens. The lens can have a convex outer contour and a concave inner contour in the manner of a converging lens, the diameter of the lens being at least three times, preferably at least four times as large as the diagonal of the largest of the LED chips. Due to the distance that the lens has in the projection from the LED chips, which is expediently at least as large as the diagonal of the corresponding chip, the radiation from the LED chips is well distributed even if it is not centered under the lens are arranged.

According to a favorable embodiment it is provided that a filter layer is arranged between the LED chips and the lens. The filter layer can be designed as a filter glass with a short and / or long pass filter and is used in particular to filter out radiation with critical radiation wavelengths below and / or above a wavelength defined as a threshold value. Such filter layers are useful in the case of broad radiation spectra from high and / or low pressure lamps, but can be dispensed with under certain circumstances in the case of LED chips with correspondingly narrow radiation spectra - a filter is particularly useful for relatively small wavelengths and / or for peaks that are close together.

According to another advantageous embodiment, it is provided that the lens has an integrated filter arrangement which prevents undesired radiation spectra from passing through and thus eliminates them. The filter arrangement is expediently a filter with a short-pass and / or long-pass filter, which prevents radiation that lies outside a desired spectrum from passing through and thus eliminates it.

However, an embodiment is preferred in which the radiation spectra of the LED chips are limited in such a way that a filter is not required. In this way, a favorable temperature development of the irradiation source is also advantageously achieved, because the waves filtered out otherwise cause an increase in the temperature and thus an increased cooling effort and a poorer efficiency.

A particularly favorable irradiation result is obtained when the radiation peaks of the LED chips are defined by a wavelength, and when the spectrum of the LED chips is more than two thirds, preferably more than three quarters, particularly preferably more than nine tenths within a bandwidth, calculable by the product of the wavelength (in nm) and a factor F (i.e. wavelength × F), whereby the factor F is selected so that it is between 1 +/- 0.005 and 1 +/- 0.05, and so encloses the radiation peak on both sides. As a result, the radiation spectrum is essentially concentrated within a width that is approximately the same on both sides of the peak, so that a particularly effective treatment of the human body with a defined radiation peak is achieved. At the same time, the extremely narrow deviation around the radiation peak ensures that harmful radiation is only emitted in a minor amount. Particularly preferably even a proportion of 99%, preferably 99.9% and particularly preferably 99.99% lies within the stated limit.

The radiation peak of the LED chips is preferred, i.e. for example the first, the second, the third, the fourth, the fifth LED chip selected from the group comprising 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; and. Certain wavelengths can be combined to form therapeutically and / or cosmetically favorable combinations with radiation intensities that are coordinated with one another, as a result of which physiological effects are achieved in the body to be irradiated. By selecting certain radiation peaks, the irradiation and thus possible damage to or stress on the human body with radiation that is not effective or that is not optimally effective is reduced and accordingly spared. The specified tolerances express that the radiation peak of the respective LED chip is not is exactly and always identically reproducible, but can vary within narrow limits.

The aforementioned radiation peaks belong to the group of cosmetically and hygienically useful radiation, without prejudice to any medical effect that may exist at the same time. In particular, the cosmetically and hygienically useful radiation produces a photobiological effect on an irradiated person. The cosmetically and hygienically useful radiation hits the person's skin, but can penetrate deeper regions of the body depending on the specific wavelength. The effect includes, for example, a tanning of the skin, but other physiological and psychological effects also result from the irradiation. Cosmetically and hygienically useful radiation comprises the spectrum of ultraviolet (UV) radiation outside the UV-C spectrum, visible (VIS) radiation and near infrared (nIR) radiation. The UV radiation outside of the UV-C spectrum has wavelengths in the spectrum between 280 nm and approx. 380 nm, the VIS radiation here has wavelengths in the spectrum between approx. 380 nm and approx. 780 nm, the nIR Radiation has wavelengths in the spectrum between approx. 780 nm and 1400 nm. The mentioned spectra merge into one another. Depending on the cosmetic or hygienic application, the irradiation can be concentrated on a sub-spectrum of the specified spectra. For this purpose, cosmetically and hygienically useful radiation-emitting arrangements can also be dedicated to individual wavelengths, e.g. UV radiation. It can be seen that the preferred radiation peaks of the LED chips cited more specifically above all fall within the range of cosmetically and hygienically useful radiation. However, the enumeration of the specifically mentioned radiation peaks of the LED chips and / or any combination thereof of two or more radiation peaks, which are hereby expressly mentioned as part of the disclosure, is not exhaustive.

Another interesting aspect here is that the combination treatment not only enables the human or animal body to be exposed to radiation with the corresponding wavelengths, but also enables these radiation peaks to be related in a targeted manner. In this way, both the intensity of the radiation and the duration and / or the sequence of the irradiations can be set in relation to one another.

The lens, which forms primary optics, is preferably followed by a collimation reflector for collimating the radiation, which reflector uniformly collimates the radiation from all LED chips and thus forms secondary optics. For this purpose, the collimation reflector is preferably designed in the manner of a truncated cone or a paraboloid of revolution with a highly reflective inner circumference, for example made of aluminum, which is cut off at the end, whereby the radiation exiting the lens is homogenized and, in particular, no relative intensity peaks arise in the area of the illuminated surface. It is particularly surprising that the same collimation reflector can also be used for wavelength ranges that differ by up to a factor of two, and that the emitted radiation strikes the human body almost homogeneously. The LED chips can be controlled accordingly to regulate the impact intensities, which can easily be achieved by measuring the body irradiation device.

The collimation reflector expediently has a small opening on the side facing the lens and a larger opening on the side facing away from the lens, which is expediently circular. Radiation passing through the lens enters through the small opening and collimated radiation exits through the large opening. The collimation reflector is thus arranged completely in front of the LED housing and the lens.

According to a favorable aspect it is provided that more than half of the LED chips are arranged eccentrically to a center point defined by the projection of the vertex of the lens onto the base. Surprisingly, it has been found that at least two LED chips with uniform radiation can be arranged particularly favorably on the base when neither the first LED chip nor the second LED chip is arranged exactly on the center point, but rather at a distance from the center point is arranged. Although this initially leads to less homogeneous illumination, this is almost completely compensated for, in particular by downstream collimation reflectors, while the arrangement of one of the LED chips on the center is more poorly homogenized by the downstream collimation reflector.

In the case of more than two LED chips, one of the LED chips is preferably arranged on a center point defined by the projection of the vertex of the lens onto the base, with that chip being selected that has a low radiation intensity and accordingly a high energy consumption if the intensity should be increased.

However, it is expediently provided that all LED chips are arranged eccentrically to a center point defined by the projection of the apex of the lens onto the base, whereby a particular through the downstream collimation reflector adjusting uniform illumination can be achieved.

According to a preferred embodiment, it is provided that at least one of the LED chips can emit pulsed radiation. The pulsed radiation can, depending on the wavelengths, preferably at wavelengths of more than 280 nm, preferably more than 700 nm, achieve favorable effects, in particular in the treatment of the human body, and have a particularly stimulating effect. It is possible to provide the pulsing of one LED chip with the pulsing of the other LED chip simultaneously or alternately. The pulsed LED chips are expediently used in the range of visible light and the near infrared spectrum. However, it is also possible to pulse the LED chips in the UV-A and UV-B spectrum.

When pulsing the LED chips, in a first advantageous embodiment the parameter pulse width ratio, that is to say the ratio on / off or the duration of the emission of radiation and the duration of the non-emission of radiation, can be set within wide limits. In a first preferred embodiment, the on-duration is equal to the off-duration. In a second preferred embodiment, the on-duration is between 25% and 200% longer than the off-duration. By pulsing the LED chips in the aforementioned pulse width ratios, a significantly better effect of the irradiation appears to be achieved, surprisingly, than when continuous irradiation takes place.

When pulsing the LED chips, in a second advantageous embodiment, which can optionally be implemented at the same time as the first embodiment, the frequency parameter, i.e. the number of on / off pulses per unit of time, can be set within wide limits. A particularly effective frequency is selected between 0.25 Hz and 500 Hz, preferably between 1 Hz and 100 Hz, particularly preferably between 8 Hz and 15 Hz, preferably at 10 Hz. Another favorable frequency is in the frequency band that is greater than or equal to that frequency is detected as intermittent by the human eye, for example above 50 Hz. Here, for example, a frequency of 60 Hz, 120 Hz or 240 Hz comes into consideration.

The separate pulsing of the first LED chips, second LED chips, etc. independently of one another, albeit possibly coordinated with one another, is also achieved by the separate controllability of the LED chips, without these further features having to be provided in each embodiment.

A plurality of lenses are expediently arranged on the carrier, each of which covers a plurality of LED chips in a respective LED housing. According to a preferred development, all radiation sources formed in this way on the carrier are designed in the same way, so that each lens covers the same number of LED chips of the same type. However, it is also possible to design the radiation sources provided on an irradiation arrangement in different ways.

According to a favorable development, it is provided that the body irradiation device further comprises a carrier on which a plurality of irradiation sources are arranged, each of which has a plurality of LED chips under a common lens. In this case, it is expediently provided that the same LED chips are uniformly controlled on the carrier.

A favorable embodiment advantageously provides that twenty irradiation sources or integer multiples thereof are arranged on the carrier. As a result, a carrier with twenty irradiation sources each can be equipped with several LED chips, which can be arranged and operated in a modular manner within a body irradiation device and nevertheless can be easily exchanged.

Provision is advantageously made for the base of the irradiation sources to be arranged in each case on the carrier. The base can for example be recessed in one piece on the carrier or it can be glued, clamped or arranged on the carrier, for example in a recess provided for this purpose. The base is preferably the base of the LED housing, which also has an annular wall and thus forms a type of chamber or receptacle. An underside facing away from the base is preferably flat and can be on a flat side of the carrier 41 be determined.

According to another favorable embodiment, it is provided that all irradiation sources on the carrier are designed in the same way, so that the respective LED chips can be controlled together, in parallel or in series. The first LED chips are controlled together, the second LED chips are controlled together, etc. Alternatively, the radiation sources on the carrier can be designed differently; in this case the LED chips have to be controlled individually. Combinations of the two designs are also possible, that is to say, for example, a field (array) of identically configured first irradiation sources and, in addition, individual second irradiation sources configured differently therefrom.

The body irradiation device expediently has an irradiation room in which the human body to be irradiated is enclosed in the manner of a tunnel, the tunnel can be designed either as a vertically aligned tunnel with a movable wall element or as a bed with a cover element that can be swung open. In order to dissipate heat, it is possible to subject the irradiation tunnel to an air stream that cools the interior of the tunnel.

The body irradiation device here preferably comprises a housing which at least partially surrounds a tunnel-like irradiation space for a person to be irradiated and which has at least one receiving space for the light sources. A partition of the housing between the receiving space and the irradiation space is advantageously formed from a material that is transparent to the radiation from the irradiation sources. The radiation from the irradiation sources is directed from the receiving space into the irradiation space.

A favorable embodiment provides that the first radiation peak is 290 nm +/- 2 nm and the second radiation peak is 297 nm +/- 2 nm. With this combination within the UV-B spectrum, the previtamin D3 can be produced inexpensively, whereby at the same time damage to the DNA of the treated person is particularly low.

Another favorable embodiment provides that the first radiation peak is 310 nm +/- 5 nm and the second radiation peak is 365 nm +/- 10 nm. With this combination of a wavelength from the UV-B spectrum and a wavelength from the UV-A spectrum, the tanning of the human skin can be achieved through pigment discoloration.

Another favorable embodiment provides that the first radiation peak is 620 nm +/- 15 nm and the second radiation peak is 660 nm +/- 15 nm. With this combination of a wavelength from the visible (VIS) spectrum, cosmetic effects, skin rejuvenation and / or wound healing can be achieved and / or promoted.

In an advantageous development it is then provided that the third radiation peak is 740 nm +/- 20 nm and the fourth radiation peak is 840 nm +/- 20 nm. This also promotes and / or achieves a wellness effect and the regeneration of tendons, fasciae and muscles.

In a further development, it is then provided that the fifth radiation peak is 465 nm +/- 20 nm. This also reduces acne on the irradiated skin.

Yet another favorable embodiment provides that the first radiation peak is 465 nm +/- 20 nm and the second radiation peak is 660 nm +/- 20 nm and the third radiation peak is 840 nm +/- 20 nm. In this way, acne on the skin in particular is advantageously regressed.

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

According to one aspect of the invention, a method for preferably non-therapeutic irradiation of a person with cosmetically-hygienically useful radiation is specified, comprising an irradiation source with a base and with at least one first LED chip that can emit a radiation spectrum with a first radiation peak, and with at least one second LED chip which can emit a second radiation spectrum with a second radiation peak different from the first radiation peak, the method being characterized in that the first LED chip and second LED chip are arranged under a common lens and are separate can be controlled. This advantageously makes it possible to match the intensity of the radiation spectra of the first LED chip and the second LED chip to one another and at the same time ensures that the radiation emitted by the radiation source hits the person to be irradiated homogeneously. The body irradiation device described above, including all of its optional developments, can be provided for the method. Preferably, in accordance with the description above, third, fourth and fifth LED chips are also possible, which are arranged under the common lens and are controlled separately. The method advantageously provides for the irradiation of a human body of a person or of a part of a human body of a person. This distinguishes it from irradiation methods that direct radiation onto objects and in which there are no health restrictions with regard to dose and radiation spectrum to be observed.

Finally, the body irradiation device comprises 1 also all necessary electrical and electronic components for operation

In 2 is an exploded view of an irradiation module 40 illustrated. It can be seen that on each surface 41a of a carrier 41 a plurality of a total of twenty radiation sources 50 are attached, each having at least one first LED chip 51 and a second LED chip 52 have that over the carrier 41 contacted with an electrical power supply are. It is possible to provide the LED chips in a different number and / or arrangement than in the present case in a 4 × 5 field arrangement.

One recognizes in 2 that on a total of six LEDs 51 , 52 a common lens 53 on the carrier 41 is shown that on the face 41a is set and which has an outwardly curved shape and for the radiation of the LED chips 51 , 52 is permeable.

The carrier 41 with the LEDs 42 , 43 upstream is a structural unit 44 with 20 identically designed collimation reflectors 44a provided, the hole size of the collimation reflectors 44a on the lenses 53 is matched. The reflectors 44a are for this purpose in one of the LEDs 42 , 43 spaced area with a washer 44b who have favourited the openings for the collimation reflectors 44a has connected, so that the structural unit 44 how a part can be handled.

The structural unit 44 upstream is an annular disk 45 that is one of the number of collimation reflectors 44a corresponding number of circular recesses 45a in a plate body, which are coated in their inner circumference with a fluorescent material. Will the LEDs 51 , 52 caused to emit the radiation, this radiation excites the fluorescent material of the rings 45a on, and because of the glowing of the rings in the visible area 45a can be seen that the LEDs 51 , 52 also emit radiation.

On the LEDs 51 , 52 opposite side of the wearer 41 is a heat transfer plate 46 arranged, which is designed as a plate body and for deriving the operation of the LED 42 , 43 resulting heat is determined. The heat transfer plate is for this purpose 46 via a first cooling line 47 and a second cooling line 47 with a heat sink designed as a heat exchanger 48 connected, between the heat transfer plate formed with cavities 46 , the first cooling line 47 , the heat sink 48 and the second cooling line 47 a circulating cooling fluid is provided. The cooling of the heat transfer plate 46 can in particular by phase transformation of the cooling fluid between the heat transfer plate 46 one hand and the heat sink 48 on the other hand can be effected.

The one in the housing part 20th or housing part 30th built-in radiation modules 40 are all constructed in the same way, but it goes without saying that the irradiation modules also depend on the light sensitivity of certain parts of the user 10 can be constructed and / or controlled differently.

In the upper part of the case 30th is a first sensor 61 provided that the characteristics of the user's body 10 , in particular its height, width, circumference and the position of the arms and legs are determined. Depending on the recorded properties of the body, the radiation modules 40 adjusted in their radiation. For example, the irradiation module 40 , which is facing away from the head end, can be completely switched off when the legs of the user of this radiation module 40 no longer cover.

The sensor 61 can alternatively or additionally contain certain skin features of the user's body 10 record, for example, the presence of tattoos, burns, wounds, birthmarks, scars, white spots, pigment disorders, the current tan and also the skin type. This second sensor, which can also be designed as a camera and to which an evaluation logic is connected, captures the color and contrasts of the skin with a high resolution and evaluates the captured images in order to determine the specified features of the body. Depending on the skin features, the radiation module is then used 40 operated with a reduced power if, due to the detected skin features, burns of the skin are to be feared with normal radiation and exposure.

Finally, it is in the upper housing part 30th a second sensor 62 arranged that the radiation of the irradiation modules 40 or the associated LEDs 51 , 52 detected. The second sensor 62 or its evaluation unit compares the detected radiation with, for example, set values stored in the controller S, and in response to a deviation of the detected values from the set values, the control causes the operating parameters of the irradiation modules 40 adjusted in such a way that adjustment to the target value results.

3A and 3B show a cross section and a top view of a first embodiment of the radiation source 50 , the schematic and not to scale the structure of the irradiation source 50 explain. The source of radiation 50 is in an LED housing 60 housed from an electrical insulator such as plastic or ceramic, which has a rectangular, in this case square, plan and has a base 61 has, the underside of which 61 u in turn on a surface of the carrier 41 , for example a highly thermally conductive plate made of aluminum, connected, for example glued on. Alternatively, the LED housing 60 can also be plugged onto a base that is on the carrier 41 is appropriate. There are also electrical lines on the carrier 41 relocated. Typically the wearer has 41 about twenty LED packages arranged in a 5 x 4 array 60 on.

On a base facing away from the underside 61a , which is substantially circular and of a ring area 62 are the first LED chip 51 and the second LED chip 52 each eccentric to a center point of the base 61a arranged. The two LED chips 51 , 52 are via corresponding conductor tracks 63 on the base 61a contacted. An electrical connection of the radiation source 50 is denoted by 64. The base 61a forms a depression above that on a ring shoulder 62a of the ring area 62 a filter layer 55 is arranged. The LED housing 60 forms a recess which has an opening in only one direction, several of which are on the carrier 41 can be arranged.

The filter layer 55 filters those from the LED chips 51 , 52 emitted radiation within specified wavelength limits, which can be specified for health reasons, for example. On a further out and further away from the base 61a lying ring flange area 62b is the lens 53 supported and held clamped circumferentially. In addition, the lens can also be glued onto the ring flange area. You can see that on the base 61a still further base areas are provided in which further LED chips can be placed. You can see that only through the filter layer 55 filtered radiation from the lens 53 can emerge.

4A and 4B show a cross section and a plan view of another embodiment of the radiation source 50 . In contrast to the execution according to 3A and 3B is not a filter layer here 55 intended. However, it is in the lens 53 a filter assembly 55a integrated that of the LED chips 51 , 52 filters emitted radiation within specified wavelength limits. It is possible to change the filter layer 55 and the filter assembly 55a in an irradiation source 50 to be provided in combination. In another embodiment, no filtering of the radiation is carried out.

However, there is a risk of overdosing if the person wants to force the treatment to be successful. It is therefore provided in an advantageous embodiment that at least one and preferably both of the two LED chips from Example 2 are also included in the irradiation source 50 is installed so that the tanning process prevents misuse.
