    LIGHTING ARRANGEMENT
    The present invention relates to a lighting arrangement for illumination by means of light in the visible spectral range and for disinfection by means of light in the ultraviolet spectral range.
    From the prior art is a variety of different disinfection methods that are used by using different disinfectants for disinfecting surfaces, facilities, rooms and the like. The particular disadvantage here is that disinfectants that are hazardous to health or the environment are often used and that disinfection of larger areas is comparatively time-consuming. Furthermore, disinfection methods are known in water treatment which disclose disinfection by means of UV radiation sources.
    Based on this prior art, the present invention has the task of providing a lighting arrangement with which surfaces, facilities, rooms and the like can be disinfected in a simple manner and which can also be flexibly adapted to a wide variety of applications can.
    [0004] These and other objects, which are mentioned when reading the following description or can be recognized by the person skilled in the art, are achieved by the subject matter of the independent claims. The dependent claims develop the central idea of the present invention in a particularly advantageous manner.
    A lighting arrangement according to the invention for illumination by means of light in the visible spectral range and for disinfection by means of light in the ultraviolet spectral range comprises at least: at least one UV light emitting diode lamp (in particular a UV light emitting diode chip) for emitting light in the ultraviolet spectral range; at least one luminous element for emitting light in the visible spectral range; Acquisition means for acquiring at least one parameter; Control means for controlling the light output of the lighting arrangement, the control means controlling an output of light in the ultraviolet spectral range at least as a function of the at least one detected parameter.
    In other words, the present invention proposes to provide a lighting arrangement that can be used not only for lighting, but also for disinfection by means of at least one UV light source.
    The term lighting arrangement is to be understood broadly in this context and includes not only classic lighting devices, but also, for example, lighting of touchpads, devices with backlighting systems, such as televisions, OLED modules and all other general lighting applications.
    The term detection means is to be understood here as any means that is suitable for detecting any parameters, such as motion sensors, temperature sensors and the like, which are suitable for controlling a UV light output of the lighting arrangement. The present invention thus provides the possibility of integrating a disinfection function into the lighting technology for lighting or of combining it with it.
    Preferably, the luminous element for emitting light in the visible spectral range is provided by at least one LED chip or by at least one OLED module or by at least one luminous material layer with luminescent material contained therein, the latter being provided by the at least one UV light emitting diode emitted light can optionally be guided to the illuminant layer in order to excite the fluorescent substance contained in the illuminant layer, so that it emits light in the visible spectral range.
    Advantageously, the lighting arrangement comprises a plurality of UV LED chips that light
    can emit in the same ultraviolet spectral range. This allows the UV intensity to be increased in a simple manner, so that disinfection is possible in a comparatively short period of time.
    Alternatively, there is the possibility that the lighting arrangement comprises several UV LED chips which can emit light in at least two ultraviolet spectral ranges. This makes it possible to disinfect at different wavelengths in the ultraviolet spectral range, which can also lead to an improvement in the disinfection result, since different germs and the like can react to different wavelengths.
    Preferably, the UV-LED chips emit ultraviolet light with a wavelength between 1 nm and 380 nm. It is also preferred that the lighting arrangement can emit light with a first wavelength between 200 nm and 100 nm (so-called vacuum UV) and light with a second wavelength between 121 nm and 10 nm (so-called extreme UV). A particularly high disinfection effect can be provided precisely at these wavelengths. Alternatively or additionally, UV-LED chips can also be used, which emit UV light in the UV-A, UV-B and / or UV-C-FUV range.
    Depending on the application or depending on the installation situation of the lighting arrangement, it can be advantageous that the at least one UV LED chip and the at least one LED chip are arranged on separate LED modules. This makes it possible to adapt the desired radiation directions of the chips and to adapt to the respective installation conditions in a simple manner.
    Advantageously, the lighting arrangement for supplying power to the at least one UV LED chip and the at least one LED chip comprises separate power supply units and / or separate control means. This makes it possible in a simple manner to control the respective chips independently of one another, for example by means of a control via the power supply.
    The lighting arrangement advantageously comprises light deflection and / or light guide elements in order to deflect or guide light from the visible and / or ultraviolet spectral range. In this context, it is preferred that the lighting arrangement for the UV LED chips and for the LED chips comprises separate light deflecting and / or light guide elements. This makes it possible in a simple manner to guide the radiation emitted by the UV-LED chips or by the LED chips into different areas of the lighting arrangement or into different emission areas.
    The lighting arrangement advantageously comprises light guides, in particular for ultraviolet light, which can be arranged manually and / or controlled on the at least one UV-LED chip in order to be able to redirect light in the ultraviolet spectral range into certain areas. For example, this makes it possible to guide UV light around the illuminant layer so that no visible secondary light is emitted, but only or essentially only light in the ultraviolet spectral range,
    Advantageously, the lighting arrangement comprises at least one shading or screen element and / or a filter element that is arranged on or in the lighting arrangement or can be optionally arranged in order to shield predefined areas from irradiation with light in the ultraviolet spectral range or only these areas be irradiated with lower intensities.
    Depending on the installation conditions or the installation location, it may be necessary not to irradiate certain areas with a comparatively hard UV light, for example to prevent undesired material aging or to prevent endangering people. Such an embodiment can be advantageous, for example, for (showcase) lights in museums that are frequently touched and therefore have to be disinfected, while the sensitive exhibits are typically arranged at the rear, which are preferably not irradiated with an ultraviolet light. Advantageously, the screen element and / or
    the filter element is also controlled or actuated by the control means.
    In particular, movement sensors, temperature sensors, pressure sensors, position sensors, piezoelectric sensors and / or manual switches can be used as the detection means. Depending on the specific installation situation, different detection means can be used or combined. If, for example, a room, an object or the like is to be disinfected by the lighting arrangement, appropriate motion sensors can detect whether there are people in the area to be disinfected so that disinfection is not started or disinfection that is already taking place is interrupted. There is also the possibility of detecting, for example by means of pressure or position sensors, whether an object to be disinfected, for example a toilet lid or a door handle, has been changed in its position or has been used, so that the detection means trigger disinfection after such an object has been used. There is also the possibility that the detection means is a manually operated switch which triggers disinfection after being operated.
    The control means are advantageously set up in such a way that the lighting arrangement emits light in the ultraviolet spectral range at predetermined times. For example, periods of time for disinfection can thereby be provided in which, with a high degree of certainty or with high probability, no persons are in the area to be irradiated or disinfected with ultraviolet light.
    [0021] The control means are advantageously connected to a network, so that an alternative or additional control of the lighting arrangement can take place by means of a central computer unit. For example, this makes it possible to disinfect several objects, facilities or rooms at the same time if, for example, it is known that there are no people in the areas to be irradiated at this point in time. This also provides the option of recording centrally when and how long a corresponding disinfection was carried out.
    [0022] The control means are advantageously set up in such a way that the lighting arrangement can emit light in the ultraviolet spectral range with different intensities, in different wavelength ranges and / or with different pulses. This makes it possible to provide different disinfection modes that can be adapted to different situations / loads. For example, shorter disinfection intervals can be provided throughout the day and longer and, if necessary, more intensive disinfection intervals at night.
    The lighting arrangement advantageously comprises acoustic and / or visual signaling means which emit an acoustic and / or visual signal when the lighting arrangement emits light in the ultraviolet spectral range. In this connection, it is preferred that the visual signaling means comprise at least one display panel which is arranged outside the area which is irradiated by the lighting arrangement with light in the ultraviolet spectral range. By means of acoustic and / or visual signaling means of this type, there is a simple possibility of minimizing the risk to people and of preventing people from being unintentionally exposed to UV radiation over a long period of time. As a visual signaling means, at least one LED chip can also be provided on the lighting arrangement, which is controlled by the control means such that it emits light in the visible spectral range when the lighting arrangement emits light in the ultraviolet spectral range.
    The control means can also be set up in such a way that they control closing and locking systems of doors and / or accesses, in particular to lock or lock them, when the lighting arrangement emits light in the ultraviolet spectral range. For example, it is possible to use movement and / or temperature sensors to detect whether there are people in an area to be disinfected and, if there are no people in the area to be disinfected, the corresponding accesses to such an area can be closed or locked .
    In a preferred embodiment, the lighting arrangement is arranged or integrated in a touchpad (or generally in devices with touch-sensitive surfaces) that light in the ultraviolet spectral range can be emitted or coupled into the touchpad surface. In particular, touchpad surfaces are exposed to a comparatively high level of germs, since these surfaces are used frequently and by different people.
    In a further preferred embodiment, the lighting arrangement is arranged or integrated on a switching or control device, in particular on light switches, in such a way that light in the ultraviolet spectral range can be emitted or coupled into the manually operable switching or control surfaces.
    In a further preferred embodiment, the lighting arrangement is arranged or integrated on a toilet seat, a toilet lid underside or a toilet lid, the lighting arrangement being arranged such that this ultraviolet light is in at least one section of the toilet seat, or the toilet lid underside, which is transparent to ultraviolet light the toilet lid can couple.
    Furthermore, the lighting arrangement can be arranged in a further preferred embodiment on or in a door handle which comprises at least one outer layer transparent to ultraviolet light, the lighting arrangement being arranged or integrated on the door handle in such a way that this ultraviolet light enters the transparent one outer layer of the door handle can couple.
    In a further preferred embodiment, the lighting arrangement is arranged or integrated on a furniture element in such a way that the lighting arrangement can illuminate and / or disinfect at least one surface of the furniture element.
    The mentioned preferred applications of the lighting arrangement are objects that are exposed to a comparatively high disposition of germs and bacteria, so that the present invention can be used particularly advantageously in these areas.
    The present invention further relates to a lighting device, in particular to an elongated lighting device, a light strip, a ceiling spotlight, a wall lamp, a pendant lamp, a table lamp, a floor lamp, a bed lamp, an operating room lamp, cabin lighting or a portable lamp, which comprises at least one lighting arrangement described above. The lighting arrangement can be arranged in such a way that light in the ultraviolet spectral range can also be at least partially emitted onto the lighting device itself. This makes it possible for the lighting device to also be disinfected as part of a disinfection.
    The present invention further relates to a lighting arrangement for illuminating food by means of light in the visible spectral range and for illuminating by means of light in the blue spectral range, comprising: at least one illuminant for emitting light in the visible spectral range; and at least one light-emitting diode illuminant for emitting light in the blue spectral range; Control means for controlling the light output of the lighting arrangement in order to be able to vary freely between illumination by means of the at least one light source for the output of light in the visible spectral range and illumination by means of the at least one light-emitting diode light source for output of light in the blue spectral range.
    In this embodiment, disinfection in the classic sense is not necessarily to be achieved, but rather (mold) fungal growth on food is prevented or at least considerably reduced by irradiation with light in the blue spectral range. It has been found that blue light, especially at around 450 nm, can significantly slow down or even prevent the growth of various types of mold (e.g. on cereals, oranges, grapes, strawberries, etc.). The present lighting arrangement can thus be used in a particularly advantageous manner in supermarkets (for example as a spotlight or emitter for meat counters or fruit stands). During the day, a loading
    Lighting with visible light or with light with a blue light component, which does not disturb the presentation of the goods, can be set and lighting with almost exclusively blue light is used at night in order to slow down or prevent mold growth.
    Furthermore, various quality defects (mold, pressure points, etc.) of the food can be seen more easily with blue lighting than with standard lighting. Thus there is also the possibility of using the adjustable blue lighting of the lighting arrangement for checking or sorting out defective food.
    The light-emitting diode illuminant preferably emits blue light with a wavelength between 420 nm and 480 nm, particularly preferably between 440 nm and 460 nm and very particularly preferably from about 450 nm. However, it is also conceivable that in addition to or instead of Light in the blue spectrum the emission of light in another visible or invisible light spectrum or with other / different wavelengths is possible, which has the corresponding properties as described above.
    [0036] The lighting arrangement is advantageously designed as a portable hand-held lighting device. This means that the staff or a customer can use such a handheld device flexibly and adjust the lighting according to their individual needs.
    The present invention finally relates to a hand-held lighting device for illuminating food with light in the blue spectral range, comprising: at least one light-emitting diode lamp for emitting light in the blue spectral range, wherein the light-emitting diode lamp is set up to blue light with different wavelengths in particular to deliver between 420 nm and 480 nm; Control means for controlling the light output of the lighting arrangement in order to be able to set lighting with light in the blue spectral range that is adapted to the food to be illuminated. Such a hand-held device is also suitable for flexible lighting by the staff or by customers, in order to be able to assess the quality of the food independently of a fixed lighting system. The respective wavelength of the blue light spectrum can be set to the specific food to be illuminated by the control means (for example a switch, a rotary slide valve or some other manual actuation mechanism). However, it is also conceivable that, in addition to or instead of light in the blue spectrum, it is possible to emit light in another visible or invisible light spectrum or with other / different wavelengths which has corresponding properties as described above. For this purpose, the hand-held lighting device can, for example, have light-emitting diodes with different wavelengths.
    Advantageously, the lighting arrangement also comprises detection means or sensor means for detecting (ie for determining) the food to be illuminated, so that the control means can automatically control or set an illumination of the food to be illuminated depending on the detection / sensor means. Such detection means can be provided, for example, by means of color sensors, photo sensors or the like. A barcode reader is also conceivable here which, based on the barcode read in, sets the light according to the product detected in this way. Based on the detected color values, the output of blue light (and / or also light of other wavelengths / spectral ranges) can then be set automatically by the control means. A color setting of the hand-held lighting device can, however, also be carried out manually or by means of preset or presettable keys, so that the emitted wavelength of the light is appropriately matched to the specific product.

In this context, it is possible for the ultraviolet light to be coupled into the luminaire surface 103 in the rear area of the luminaire surface 103 and / or in the lateral area of the luminaire surface 103. Furthermore, there is also the possibility that the luminaire surface 103 is directly irradiated with ultraviolet light, for example by arranging the UV-LED chips 102 on the side on the front side of the luminaire surface 103.
    The lighting arrangement 100 furthermore comprises acquisition means (not shown) for acquiring at least one parameter, with the aid of which control means (not shown) control at least the emission of light in the ultraviolet spectral range.
    The term detection means is to be understood broadly in the present case and includes in particular movement sensors, temperature sensors, pressure sensors, position sensors, piezoelectric sensors and / or manual switches that detect at least one parameter (for example the presence of a person in the area to be irradiated or in the area to be disinfected Area) with the help of which a UV light emission can be controlled.

Of course, depending on the application, the present invention can also be used without light guide elements. The present invention is also not limited to the use of reflector arrangements as light guide elements; for example, lens elements, grating elements and the like can also be used.

Such a lighting arrangement 300 is particularly advantageous when certain areas are not to be irradiated with UV light, for example in museums, where sensitive exhibits are not to be irradiated with comparatively hard UV light, in order to be able to avoid material aging of these exhibits.

As can be clearly seen in FIG. 5, the respective chips are arranged separately from one another and each comprise light deflecting or light guide elements 503, 504 (for example in the form of corresponding lens, grating and / or reflector arrangements) to separate the respective light to be able to manage the areas intended for irradiation or disinfection.
    FIG. 6 shows a schematic view of a further preferred embodiment of a lighting arrangement 600, the lighting arrangement 600 preferably exclusively comprising UV-LED chips 602.
    As can be clearly seen in FIG. 6, the lighting arrangement 600 furthermore comprises a reflector arrangement 603, which is designed such that at least one illuminant layer 604 with the luminescent material contained therein can be arranged, wherein the luminescent material can be excited by UV light in such a way that thereby light can be emitted in the visible spectral range.
    The luminous means layer 604 can be pushed into the beam path by an actuating arrangement (not shown) controlled by the control means, or it can be designed such that it can be pushed into the beam path manually.

    71717
    lengang or in such a way in the reflector arrangement 603 that the lighting arrangement 600 only emits light in the visible spectral range. In the disinfection mode (right partial view of FIG. 6) the illuminant layer 604 is swiveled out of the beam path or removed so that light in the ultraviolet spectral range can be emitted for disinfection by the lighting arrangement 600.
    FIG. 7 shows a schematic view of a further preferred embodiment of a lighting arrangement 700, which in turn preferably exclusively comprises UV-LED chips 702.
    As can be clearly seen in FIG. 7, the lighting arrangement 700 further comprises a reflector arrangement 703 and a luminous means layer 704 arranged in the reflector arrangement 703, which in turn can emit (secondary) light in the visible spectral range when this is caused by the UV LED Chip 702 is irradiated with ultraviolet light.
    In contrast to the exemplary embodiment shown in FIG. 6, the lighting arrangement 700 shown in FIG. 7 furthermore comprises light guides 705 which can provide a type of bypass for ultraviolet light around the illuminant layer 704. The light guides 705 can in turn be arranged accordingly manually or automatically or be opened and closed electronically, so that ultraviolet light can optionally be guided through the luminous means layer 704 or around the luminous means layer 704.
    [0070] There is also the possibility of using a shading or shading that is reflective on one side. Provide cover element 706 that in the disinfection mode (ie when ultraviolet light is guided around the illuminant layer 704) is arranged in front of the illuminant layer 704 (again either automatically or manually), so that in disinfection mode no light is emitted in the visible spectral range and essentially the entire emitted UV light can be used for disinfection.

    The upper partial view of FIG. 8 shows the lighting arrangement 800 in a lighting mode in which light is emitted in the visible spectral range. The lower partial view of FIG. 8 shows the lighting arrangement 800 in a disinfection mode in which light is emitted in the ultraviolet spectral range.
    As can be clearly seen in FIG. 8, the lighting arrangement 800 comprises a light-emitting element 803 into which ultraviolet light can be coupled by means of corresponding light guides 805, it being possible to switch from the lighting mode to the disinfection mode by means of an electronic control or by means of a mechanical (possibly by manually pushing the element 803 apart. For illumination with light in the visible spectral range, the lighting arrangement 800 can comprise LED chips (not shown) or a light source layer (not shown) that is arranged in front of the element 803 in the direction of radiation, so that in Lighting mode secondary light of the illuminant layer can be emitted.

    view of Figure 10) or the OLED module 1000 can backlight, i.e. Can guide ultraviolet light through the OLED module (lower partial view of Figure 10).
    The lighting arrangements shown and described above can be used in particular for disinfecting a wide variety of surfaces, such as touchpad surfaces, switching or control devices, toilet facilities, door handles, furniture elements or the like, in order to be able to provide disinfection of corresponding surfaces and facilities.
    The detection means can be adapted to the specific application, for example, to be able to trigger disinfection (for example after flushing the toilet) and furthermore to prevent people from being unintentionally exposed to ultraviolet radiation. Furthermore, it is particularly preferred that disinfection is carried out at predetermined times and the lighting arrangement comprises corresponding means for time control.
    Furthermore, with the lighting arrangements described above, different lighting devices can be provided, such as in particular elongated lighting devices (for example light strips), ceiling spotlights, wall lights, pendant lights, table lamps, floor lamps, bed lights, surgical lights, cabin lighting of aircraft or portable lights.
    The present invention can be used particularly advantageously in the context of medical care, for example in the form of lights for hospital beds, with which on the one hand lighting in the visible spectral range can be provided when a patient is in bed and, if the patient is is not in his bed, the bed can be disinfected.
    For example, the lighting arrangements described above can also be used advantageously in aircraft cabins, where a lighting function is provided during normal flight operations and an additional disinfection function is provided when there are no people in the aircraft cabin.
    The present invention is not limited to the preceding exemplary embodiments as long as it is covered by the subject matter of the following claims. In particular, it should be noted that the above-described exemplary embodiments of the preferred lighting arrangements, in particular their respective technical aspects, can be combined with and with one another in any way.
