    3D PRINTING PROCESS FOR MANUFACTURING A LUMINAIRE ELEMENT WITH OPTICAL PART
    The present invention relates to a 3D printing method for producing a lighting element with an optical part and a lighting element produced with the method and a lamp equipped with the lighting element.
    Optical parts or optics are well known from the prior art and basically fulfill the purpose of directing light. For various reasons, it can be advantageous to introduce light-conversion materials or other light-influencing materials into corresponding optical parts or optics. These are distributed, for example, mixed into the optical material used to produce an optical part, for example by means of injection molding processes, and are then present in the optical part in an undefined distribution after it has been produced. In this case, the light conversion substances are arranged in a correspondingly chaotically distributed manner in the optical part, which is generally designed as a volume body. The aim of corresponding conversion substances (phosphors) is to convert the light introduced into the optics, for example, from one wavelength to a defined other wavelength in a targeted manner and thus to bring about a targeted wavelength change, wavelength shift or color change. Wavelength changes or shifts or color changes caused, for example, by the optics (for example by their geometry) can also be generated or corrected. Other light-affecting materials can cause other light-affecting properties; for example, scattering particles can cause light scattering of light guided through the optics.
    It is now an object of the present invention to provide a manufacturing method for a lighting element with an optical part, by means of which a defined and targeted provision of light influencing materials - such as color conversion substances - is made possible in the optical body of the optical part in a simple manner; as well as a correspondingly manufactured lighting element itself and a lamp equipped with it, which are equipped with correspondingly defined properties in a simple manner.
    According to a first aspect, the present invention therefore relates to a 3D printing method for producing a lighting element. The lighting element has at least one optical part for guiding the light with an optical body made of an optical material. During the 3D printing of the optical body from the optical material, a locally defined light influencing material is also printed at the same time in order to form at least one locally defined light influencing region in the printed optical body. In this way, the lamp element is manufactured.
    By using the 3D printing process to produce a lighting element with an optical part, the present invention makes it possible for the first time to provide light-influencing materials in a targeted manner in the optical body by printing these materials at the same time. It is thus possible to spatially selectively arrange the light influencing materials in a volume body forming the optic body and thus to form a lighting element. Using the 3D printing process, the light-influencing materials can be introduced at defined positions even with complex optics. This creates lighting elements or optical systems with integrated light-influencing areas that are locally tailored to the respective application. In this way, lighting elements are created with optical parts that, for example, also change the spectrum in a spatially resolved manner or can influence the light in a different way in a locally precise manner. Depending on the light influencing material used, the light can be converted into a desired color in a spatially resolved manner, or color errors (e.g. from LEDs or due to chromatic aberration) in the volume can be corrected. Thus, the lighting element with an optical part or the optical system (e.g. an LED lens) can, in addition to the function of directing the light, also have the function of influencing the light - such as the
    Color correction or adjustment of the light color - meet. Depending on the light influencing material, the light can of course also be optically influenced in other ways; e.g. be spread. Overall, the method according to the invention thus serves to produce lighting elements with optical parts with a higher light quality than conventionally produced lighting elements with optical parts with a comparable function.
    The light influencing material can be printed in a locally defined manner in order to form a plurality of locally defined light influencing areas in the printed optical body. Insofar as it is basically possible in a simple manner with the 3D printing method, the light-influencing materials can be provided at any point and thus any number of light-influencing regions can be formed or provided in the optical body. This leads to a further optimization of the lighting element or optical part due to the locally defined provision of light-influencing areas.
    The or the light influencing areas can be printed with the same or at least partially with different light influencing materials or have them. In this way, it is possible to provide locally defined light-influencing materials in an optical part, depending on requirements, and thus to further optically optimize the lighting element or the optics overall.
    The light influencing materials can include, for example, light conversion materials, inorganic phosphors, organic phosphors, quantum dots (“quantum dot” also referred to as “quantum dot” or “QD” below), and/or light scattering materials. With the first four mentioned, a targeted light conversion for generating light of a different color can be generated, for example in order to bring about color corrections or the adaptation of the light color in a targeted manner. The wavelength of the light or its spectrum can thus also be changed or shifted; this with the same or changing color range. With light-scattering materials, it is possible to achieve defined light scattering at defined locations or areas of the optical part, in order to further improve the optical function of the lighting element or its optical part.
    The at least one light-influencing area can be printed with a defined layer thickness and/or a defined shape. The at least one light-influencing area can also be printed in one or more layers. Thus, the light-influencing areas can be provided in a defined manner not only with regard to their position, but in particular also with regard to their shape and layer thickness and layer structure or layer composition, and thus the lighting element or optical system can be further optimized overall.
    The at least one light influencing area can be formed in the optic body in such a way that when the lighting element or its optical part is used with a lamp for the defined guidance of light from the lamp through the optical part or its optic body, it has a (defined) influencing of the light causes. For example, this preferably defined influencing of light can be or bring about a wavelength change, a wavelength shift, a spectrum change and/or a spectrum shift of the light; this with or without changing a color range. The preferably defined light influencing can also be or bring about a change in the color of the light. The light influencing can preferably be a local influencing of the light, which can be implemented in a locally defined manner due to the locally defined provision of the light influencing regions.
    The optical body can be printed in such a way that the optical part has at least one defined optical area. The defined optical area can be, for example, defined optical structures and/or contours and/or cavities. In this respect, the optic body can be of any complex design. This is a particularly big advantage of a 3D printing process. The defined optical area can preferably be provided in such a way that it optically interacts with the at least one light influencing area when using the lighting element or optical part with a light source for defined guiding of light from the light source through and/or out of the optical body.
    In this respect, the optical areas and the light influencing area(s) can be provided locally and thus also optically defined in order to provide the lighting element or the optical part and its light influencing function in a targeted and exact manner.
    The optical part can be a lens which has a lens body as the optic body. In principle, all possible types of optical parts are conceivable. In particular, a lens as the optics is particularly preferred, since it represents a preferred element for directing the light.
    The optical material can be an optical plastic or glass or another optical material. The invention is not limited to this, provided that the materials can be used by means of 3D printing processes.
    The lamp element can also have a lamp body or other structural or optical elements/components of a lamp. The lamp body or any other elements/components can be printed together with the optical part or the optical body. The material of the lamp body or the other elements/components can be selected as desired and according to their intended use, provided they can be used in the 3D printing process. There are therefore no limits to the design and functions of the lighting element.
    [0015] The so-called drop-on-demand (DoD) method, for example, can be used as a 3D printing method. Here it is preferably conceivable that a separate material nozzle is provided for each material, so that the optical material on the one hand and each light-influencing material on the other hand (and possibly material for the lamp body and any other elements/components) are each provided by their own material nozzle - preferably dispersed in a matrix - can be applied locally. In this way, lighting elements or optical systems with integrated light conversion materials that are locally tailored to the respective application are created in a particularly simple manner. Of course, other known 3D printing methods or those that will be new in the future are also conceivable and included in the invention as possible 3D printing methods.
    According to a further aspect, the present invention also relates to a lighting element which was produced by a 3D printing method according to the present invention. The lighting element produced in this way has an optical part with an optical body made of an optical material, with at least one locally defined light-influencing area being provided in the optical body. The advantages of such a lighting element or optical part have already been described in detail above and apply in the same way at this point.
    [0017] Several locally defined light influencing areas can be provided in the optical body. The light influencing area or areas can have the same or at least partly different light influencing materials. The light influencing materials can have light conversion substance materials, inorganic phosphors, organic phosphors, quantum dots (Quantum Dots; QDs), and/or light scattering materials. The at least one light-influencing area can have a defined layer thickness and/or a defined shape. The at least one light-influencing area can be printed or constructed in one or more layers. The at least one light-influencing region can be formed in the optical element in such a way that when the lighting element or the optical part is used with an illuminant for defined guidance of light from the illuminant through the optical body, it influences the light; preferably causes a local defined light influence. The influencing of the light can be a wavelength change, a wavelength shift, a spectrum change and/or a spectrum shift of the light; this preferably with or without changing a color range of the light. Influencing the light can also be a change in the color of the light. The optical part can have at least one defined optical area, such as defined optical structures and/or contours and/or cavities, with the defined optical area preferably being provided in such a way that when the lighting element or its optical part is used with a light source for defined guiding of light of the illuminant through and / or from
    the optical body interacts optically with the at least one light influencing area. The optical part can be a lens which has a lens body as the optic body. The optic material can be an optical plastic or glass or any other optical material suitable for use in a 3D printing process. The lamp element can also have a lamp body which is printed together with the optical part and is preferably formed integrally with it.
    The advantages of the above-described features of the lighting element with an optical part have already been described in detail in the explanations for the first aspect of the present invention with regard to the 3D printing process and apply in the same way to the lighting element or its optical part itself, so that here on corresponding repetition is omitted and reference is made to previous statements.
    According to a third aspect, the present invention further relates to a lamp (e.g. a spotlight or a spot lamp) having a lamp element according to the present invention and a lamp for emitting light. The light is guided at least partially through the optical part for light guidance, with at least part of the light guided through the optical part interacting optically with the at least one light-influencing region. In other words, the illuminant emits light into the optical part (e.g. into a preferably defined light coupling area of the optic body) of the lighting element, which is guided accordingly due to the structure of the optic body, while at the same time it continues to have an optical effect when it hits correspondingly locally defined light-influencing areas, so that the optical function of the lighting element or the optical system or the optical part is further optimized before the light leaves the lighting element or the optical part or the optical body; preferably defined via the optical structures.
    The light source preferably has an LED light source, a conventional light source, such as an incandescent lamp or halogen lamp, and/or a laser. All common LED types are conceivable as LED illuminants. For example, the illuminant can be an LED chip or an LED module of any design. An LED matrix can also serve as a light source. It is also conceivable to provide RGB LEDs or OLEDs as illuminants. The lamps can be controlled in any way to generate different light emission characteristics (radiation direction, radiation position, light color, luminosity, etc.).
    In addition to the lighting element with optical part and the light source, the light according to the invention can also have all other conceivable features of a light, such as electronics (e.g. driver electronics), a light body, for example. Having a housing, wiring, sensors, control units, a Cover, seals, etc. The lighting element can be used, for example, in a separately provided lighting body or connected to it. However, the lamp body can also be printed at least in part as part of the lamp element using the 3D printing process and can therefore preferably be formed integrally with the optical part. The lighting element can therefore preferably have the lighting body (at least partially). The lamp body, which is provided separately or formed integrally, can preferably carry or accommodate the lighting means.
    Further configurations and advantages of the present invention are described below with reference to the figures of the accompanying drawings. Show it:
    Figure 1 is a schematic representation of a lamp according to the invention with a lighting element according to the invention produced by a method according to the invention according to a first embodiment of the invention, and
    Figure 2 is a schematic representation of a lamp according to the invention with a lighting element according to the invention produced by a method according to the invention according to a second embodiment of the invention.
    Figures 1 and 2 each show exemplary embodiments of a lamp 10 according to the invention with a lighting element 9 according to the invention, which is produced by the 3D printing method according to the invention.
    The lighting element 9 here has an optical part 1 with an optical body 2 made of an optical material. The optical material can preferably be an optical plastic or glass. Other optical materials are also conceivable, which can be printed in particular in a 3D printing process.
    The optical part 1 is preferably a lens, as illustrated. In this case, the optic body 2 forms the lens body. The optic body 2 or the lens body are generally designed as a volume body. As can be seen from the figures, at least one locally defined light influencing area 3 is provided in the optic body 2 . As can be seen from the exemplary embodiments in the figures, a plurality of locally defined light-influencing regions 3 can preferably be provided. A total of twenty-five locally defined light influencing regions 3 are provided in the illustrated exemplary embodiments. The light influencing regions 3 can have the same or, as shown in FIGS. 1 and 2, at least partially different light influencing materials. Partly means here in particular that a part or a group of the light influencing areas 3 are made of a first light influencing material, a second part or a second group of the light influencing areas 3 are made of a second (different) light influencing material and so on. In the present exemplary embodiment, the optical body 2 has two groups of light-influencing areas 3, which are shown as black circles (group 1; here eighteen light-influencing areas 3) and white circles (group 2; here seven light-influencing areas 3). The number of groups and the light influencing areas 3 having them is of course not limited by the invention. By providing or providing different parts or groups of light influencing areas 3, the light influencing areas 3 cannot only be provided in a locally defined manner. It is also possible to use different light influencing materials to design and arrange the corresponding locally defined light influencing areas 3 according to the desired light influencing function. This can make it possible, for example, to position light-influencing materials, such as conversion substances, in different types and/or concentrations exactly in an optical volume 2 that fulfills an optical function (i.e. a defined spatial arrangement in the volume) in order to, for example, adjust the light spectra to modify it in a location-dependent manner or to scatter light in a locally defined manner or to influence it in a defined manner in another way.
    The light influencing materials can have, for example, light conversion materials, inorganic phosphors, organic phosphors, and/or quantum dots (quantum dots; QDs), for example to convert the light locally defined into a desired color or for example color errors (for example from LEDs or chromatic aberration ) in the solid to correct. Alternatively or additionally, it is conceivable that the light-influencing materials have light-scattering materials. In this way it is also possible to scatter light in the optical body 2 in a locally defined manner.
    The at least one light influencing region 3 can have a defined layer thickness and/or a defined shape. A circular or spherical shape is shown here purely as an example; In principle, any shape and layer thickness possible with a 3D printing process is conceivable. In this way, the light-influencing area can not only be provided in a locally defined manner, but can also be formed optimally in terms of its shape and layer thickness at the defined position. In addition, the at least one light influencing area 3 can be printed or constructed in one or more layers. In particular with a multilayer structure, the light influencing area 3 can be built up in layers in any way and possibly also with different materials or material combinations (e.g. according to the layer structure given by the 3D printing process) in order to enable optimal light influencing.
    The at least one light influencing region 3 can be formed in the optic body 2 such that when using the lighting element 9 or its optical part 1 with a light source 7 for defining the guiding of light from the light source 7 through the optic body
    2 causes a preferably defined influencing of the light. This can preferably be a locally defined light influencing. The influencing of the light can be a wavelength change, a wavelength shift, a spectrum change and/or a spectrum shift of the light, this preferably with or without changing a color range of the light. Influencing the light can also be a change in the color of the light. The light influencing can thus be achieved in particular by the locally defined and preferably also different light influencing materials and thus light influencing regions 3 .
    The optical part 1 can also have at least one defined optical area 4, 5, 6. These optical areas 4, 5, 6 can in particular be defined optical structures and/or contours and/or cavities. The defined optical area 4, 5, 6 can preferably be provided in such a way that when the lighting element 9 or its optical part 1 is used with an illuminant 7 for the defined guiding of light from the illuminant 7 through and/or out of the optic body 2 the at least one light influencing area 3 interacts optically. In the present exemplary embodiments, the light from the illuminant 7 is introduced into the optics 1 through a light entry area 4, can be totally reflected here, for example, via side walls 5 of the optical part 1, and is ultimately emitted in a targeted manner via a light exit area 6 of the optical part 1. On its way through the optics 1, the light is influenced and guided in an optically optimized manner due to the optimized design of the optical part 1 to enable both defined light guidance and the locally defined light influencing regions 3; consequently, the guidance of the light and the influencing of the light are optimally matched to one another or can be matched.
    As can be seen from the figures, a lamp body 8 can also be provided. As shown in FIG. 1, this can be provided as a separate part of the lamp 10 . The lamp element 9, which according to FIG. 1 only has the optical part 1, can then, for example, be rigidly connected to the lamp body 8 or movably coupled to it and thus be carried or accommodated by it. It is also conceivable that the lamp body 8 is also printed by means of a 3D printing process. The lamp body 8 can then preferably be printed together with the optical part 1; these components are then preferably formed integrally with one another as the lighting element 9, as is shown by way of example in FIG.
    The combination of the lighting element 9 according to the present invention and a light source 7 for emitting light forms a light 10 according to the invention. The light from the light source 7 is guided at least partially through the optical part 1 for light guidance, with at least part of the light guided through the optical part 1 interacts optically with the at least one light influencing region 3 . The light source 7 can preferably have an LED light source and/or a laser and/or another light source of any type; an LED module is shown here as an example.
    As described and shown in FIG. 2, the lighting element 9 can have the lighting body 8 which then preferably carries or accommodates the lighting means 7 . As described and shown in FIG. 1, a separate lamp body 8 can also be provided, which preferably carries or accommodates the lamp element 9 (only having the optical part 1 here) and the illuminant 7 . The lamp body 8 can also carry or accommodate other lamp components. In addition to the lighting element 9 with the optical part 1 and the light source 7, the light 10 according to the invention can also have all conceivable other elements/components of a light, such as electronics (e.g. driver electronics), cabling, sensors, control units, a cover, reflectors , seals, etc. All of these can also be carried or received by the lamp body 8 (separate or at least partially integrally formed as part of the lamp element 9).
    In the following, a 3D printing method according to the invention for producing a lighting element 9 having at least one optical part 1 for directing light with an optical body 2 made of an optical material is described. During the 3D printing of the
    Luminaire element 9 or the optic body 2 made of the optic material is locally defined, the light influencing material also printed in order to form at least one locally defined light influencing region 3 in the printed optic body 2 . The light influencing material is preferably also printed in a locally defined manner in order to form a plurality of locally defined light influencing regions 3 in the printed optical body 2, as can be seen from the optical parts 1 according to FIGS. 1 and 2 (shown here as white and black circles by way of example).
    The one or more light influencing areas 3 can preferably be printed with the same or, as shown, at least in part with different light influencing materials or have them.
    As already described, the light-influencing materials can have, for example, light-conversion substance materials, inorganic phosphors, organic phosphors, quantum dots (QDs) and/or light-scattering materials.
    The at least one or all light-influencing areas 3 can be printed with a defined layer thickness and/or a defined shape. The at least one light influencing area 3 can also be printed in one or more layers. All of this is made possible by the 3D printing process, which can usually produce a particularly defined material structure through layered structure with selective or layered or area application of material, whereby this can also be implemented with the most complex structures with high accuracy.
    The at least one light influencing region 3 can be formed in the optic body 2 in such a way that when the lighting element 9 or its optical part 1 is used with a light source 7 for the defined guidance of light from the light source 7 through the optic body 2, it has a preferably defined light influencing effect and preferably brings about a locally defined influencing of the light. The influencing of the light can be or bring about a wavelength change, a wavelength shift, a spectrum change and/or a spectrum shift of the light, preferably with or without changing a color range of the light. The influencing of the light can also be or bring about a change in the color of the light.
    The optical body 2 can also preferably be printed in such a way that the optical part 1 has at least one defined optical area 4, 5, 6, such as defined optical structures and/or contours and/or cavities, with the defined optical area 4 , 5, 6 is preferably provided in such a way that when the lighting element 9 or its optical part 1 is used with a light source 7 for defined guidance of light from the light source 7 through and/or out of the optic body 2 with the at least one light influencing region 3 optically works together.
    The optical part 1 can be a lens or can be designed as a lens which has a lens body as the optic body 2 .
    The optical material can be an optical plastic or glass or another optical material which is particularly suitable for use in a 3D printing process.
    The lamp element 9 can also have the lamp body 8 which is preferably printed together with the optical part 1 or the optical body 2 . These components of the lighting element 9 are then preferably formed integrally with one another. Other elements/components of the lamp 10 can also be printed with a/the 3D printing process and preferably also form an integral part of the lamp element 9 .
    The so-called drop-on-demand (DoD) method can be used, for example, as a 3D printing method. For this purpose, it is preferred that a separate material nozzle is provided for each material, ie for each optical material and for each light-influencing material (and possibly for each lamp body material). The respective materials are applied in a locally defined manner by means of the respective material nozzles, so that a defined structure of the optical body 2 (and, if applicable, of the
    Luminaire body 8) is made possible, while at the same time locally defined in the optical part 1 and tailored to the respective application integrated light influencing materials are provided or introduced and thus the locally defined light influencing areas 3 can be formed. Of course, this can also be achieved with any other 3D printing method, so that the invention is not limited to any specific 3D printing method.
    The present invention is not limited to the embodiments described above, provided that it is covered by the subject matter of the following claims. In particular, any known 3D printing method for producing a lighting element 9 having at least one optical part 1 for directing light with an optical body 2 made of an optical material is conceivable. Any possible optical part for directing light is conceivable as the optical part 1, such as in particular lenses and other optical elements. The optic body 2 is designed in particular as a volume body, which can have simple (for example symmetrical or rotationally symmetrical) shapes or also any complex structures or shapes, as is the case with Fresnel lenses, for example. The configuration of the optic body 2 is not limited by the present invention and it can take any form as already described. The lamp element 9 can only include the optical part 1, or also have other components (integrally), such as the lamp body 8 and other structural or optical (lamp) components. All conceivable optical materials that can in principle be used in a 3D printing process can be used as optical materials. The same applies to materials of other components, which are also preferably printed as part of the lighting element 9 . Likewise, any light influencing material is conceivable which is suitable for influencing light and can also be used in a 3D printing process. The number, shape, concentration, layer thickness and the like of the light-influencing regions 3 are not limited by the present invention. Likewise, the number of different materials to be used, and here both the optics material and in particular the light influencing material and also materials of other components in particular of the lighting element 9, is not limited by the invention. Likewise, depending on the material, the same or different material nozzles can be used for 3D printing, as well as it is preferred for the 3D printing process depending on the desired specification. With regard to the lamp according to the invention, the present invention is also not limited to a specific light source or a specific type of light source. It goes without saying that any conceivable light source can be used as the light source 7 . LEDs and lasers are particularly preferred here, since the use of light influencing materials and preferably light conversion materials (phosphors) is particularly preferred for these and here in particular a defined light influencing such as a wavelength change, a wavelength shift, a spectrum change, a spectrum shift, a color change and / or a light scattering of the light for the targeted emission of light and also for the correction of undesired color deviations can be used effectively. The features of the exemplary embodiments can be combined with one another and interchanged with one another in any desired manner.
