Abstract

Light-technically accentuated, at least partially spatially delimiting spatial structure, characterized by laser light (11) fanned out in a plane (30), the plane (30) being oriented so that the laser light forms a line (31) on delimiting areas of the spatial structure.

Description

The present invention relates to a light-technically accentuated, spatially delimiting spatial structure and a device for the light-technical accentuation of spatially delimiting spatial structures, as well as a system with several such devices for the light-technical accentuation of spatially delimiting spatial structures.

Within the meaning of the invention and its possible applications, a distinction can be made between the lighting technology accentuation of the delimited surfaces themselves, or the material border that at least partially delimits them, whereby both effects can of course also occur at the same time. To accentuate the surface itself, suitable suspended particles are required in the medium to be illuminated, for example fog in the air. Since two effects can be generated with this invention, or two problems can be addressed, application examples and devices for both effects are listed in the description and the drawings.

Optical or mechanical 360-degree laser systems for marking points or objects or for defining paths or reference lines, equipped with 360-degree optics, for example in the form of a reflective cone, such as in EP2469226A2 disclosed, or in the implementation of a rotary laser, have been used for many years in the industrial sector or in construction.

Laser devices and systems in the form of simple, sharp narrow-beam, less sharp, broad-beam point lasers or often in the form of laser projectors have been used for many years in the event and marketing sector as well as for special architectural stagings.

The well-known effect point lasers described have the formal limitations of simple thin rays, whereas the description of simple or complex geometric shapes by the known laser scanners (laser projectors) is always associated with a strong divergence of the individual rays towards the projection source and special spatial requirements relating to the projection. A clear spatial staging by means of laser light is severely limited in its formal possibilities due to the mentioned properties of existing systems, since the simple beam a) lacks area or b) always tapers towards the source in the case of a projection. In addition, these effects that are possible using existing systems are well known.

For the appealing staging of larger areas, where a projection using a projector or laser projector is not possible due to space and design reasons, LED screens are particularly suitable, which can be combined as modules to form larger areas.

However, these systems are associated with enormous investment costs, especially for large areas, and due to the high energy consumption they are also very expensive and not very sustainable during operation. Furthermore, this creates a lot of heat, so that additional cooling is often required, which in turn sometimes leads to noise emissions and places further demands on the room and its air conditioning. In addition, they are particularly large and heavy, complex to install and not particularly portable even when dismantled. Furthermore, the installation of such systems is also a major architectural intervention, which is not only technically and acoustically disadvantageous, but in particular also when rooms are used multiple times, i.e. when rooms are used in which they are not used, can also be formally and visually disruptive . The space to be recorded is built up and blocked by the effect, so installing a screen in a passage is unthinkable, for example.

the EP2469226A2 discloses an optical system for beam shaping of a laser beam and a laser system with such an optical system. Here, an optical element can spread a laser beam at least in sections in a plane. Accordingly, the production of line and point markings on walls is intended as a technical construction aid.

Laser projectors are devices in which a laser beam is deflected in a defined manner in two directions and which thus span a plane orthogonal to the undeflected laser beam. Two mirrors which can be pivoted about orthogonal axes and which are mostly operated by galvanometer scanners are preferably used as the deflection device.

The power of the laser beam can be regulated and / or its spectral composition can be influenced in a defined manner before it is deflected in direction. Such laser projectors have been known for many decades and have found widespread use in the event sector and in advertising. Reveal along with others US4838632A and DE3435167A such deflectors.

At events or in the marketing sector, the main aim is to attract the attention of the audience and to entertain them with impressive and novel effects.

It is particularly advantageous if with a particularly small, light, transportable and An easy-to-install system, a larger area can be used with completely new and impressive effects, while at the same time using sustainable low material and energy consumption.

The present invention is based on the object of providing a light-technically accentuated, at least partially spatially delimiting room structure, a device and a system for lighting accentuation of spatially delimiting room structures with which larger areas and architectural elements such as window reveals are simple, inexpensive and ecological , Windows, window facades, shop windows, passages, joists, projections, columns, arches or the like can be set in scene in a sophisticated way, while the device itself can be installed almost unnoticed and without great effort due to its small size.

This object is achieved by the lighting technology accentuated, at least partially spatially delimiting room structure according to claims 1 to 3, a device for lighting accentuation of spatially delimiting room structures according to claims 4 to 9 and by the systems according to the invention for lighting technology accentuation of spatially delimiting room structures according to claims 10 until resolved.

Due to the two-dimensional character of the effect, the invention offers the possibility of being able to design rooms three-dimensionally with light and fog effects only, so that expensive and heavy construction material can sometimes be dispensed with for stage shows. This not only lowers the one-time costs, but also minimizes the running costs and the time required for assembly and dismantling.

Furthermore, the system does not require a projection surface, as the two-dimensional effect occurs in the room itself. So there is no need to stretch a projection surface or to have a smooth, light-colored wall or ceiling. This property has many advantages. On the one hand, such areas are not available in many event locations, as other technical systems for acoustics, air conditioning, electricity, fire protection and other lighting and effect devices are often installed on the ceilings and walls or these are not designed flat, smooth and bright in many places anyway, on the other hand, such surfaces have unfavorable acoustic and optical properties, which must be eliminated as a rule, and many of the aforementioned technical systems must not be covered in order to be able to fulfill their purpose and possibly also legal requirements.

A particular advantage of laser light over conventional light is the high luminance of the laser beams and the low beam divergence. This makes it possible to use visual effects on larger areas without increasing the basic lighting of the room through strong light scattering. Due to the high contrast, clear effects can be created, while unlit elements of the room are at the same time optically in the background. For example, the aforementioned technical devices in the room can be hidden behind the effect produced by the invention, so to speak, without their function being hindered. The device according to the invention or the system according to the invention can easily be combined with existing and conventional lighting technology, since this is not covered or hindered in its function by the subtle systems according to the invention.

It should also be mentioned that due to the properties of laser light mentioned and the possibility of generating the surface effect in empty space, for which there is no need for additional elements or devices besides suspended particles, e.g. in the form of fog, the system is easily scalable. Rooms, surfaces and structures of different dimensions can be used equally. This makes the system particularly flexible and versatile. If several devices are necessary due to a discrepancy in the relationship between room size and light output of the system or due to a special, e.g. angled, geometry of the spatial structure, these can be combined easily and in any quantity, synchronized with one another and integrated formally and in terms of control technology into existing systems . When using weak laser light sources of the appropriate power and protection class, passages can also be played with a light level effect or “light curtains” can be used as visual room dividers.

If the inner or outer appearance of buildings is to be adorned with luminous lines or edges as a graphic effect or eye-catcher for marketing purposes, LED strips or spotlights with special optics have so far been the best choice. LED strips have the disadvantages that they often cannot be retrofitted well and they often involve too much intervention, especially in the case of listed buildings. In addition, with longer LED strips, individual lamps fail again and again, which often requires a complete and time-consuming change of a larger strip segment for correction. Lighting with LED spotlights or spotlights with conventional light sources have the disadvantage of the high divergence of the light and the associated design restrictions and the increased light pollution of the environment through undesired scattered light. In addition, both have a significantly higher consumption compared to an alternative based on laser light. Furthermore, the monochromatic character of laser light offers further advantages with regard to the protection of insects and nocturnal creatures compared to LEDs and conventional light sources, especially those that have a high UV component.

If a device according to the invention or a system according to the invention is used on, in or in front of windows, in passages, breakthroughs, arches, projections, beams, columns or the like, architectural elements can be particularly emphasized and entire facades or building ensembles can be presented in a very cost-effective and energy-efficient manner . The invention thus provides an inexpensive and reversible solution that is also particularly suitable for subsequent installation. By using windows on buildings with larger window facades, media facades can be created in a simple and inexpensive, low-maintenance and particularly energy-efficient manner, which can also be installed later without any major technical or architectural interventions. External use of a device according to the invention or a system according to the invention can also create interesting effects in the area of the light-technically accentuated structure through naturally occurring floating particles such as fog, dust or rain, in which the object and its surroundings are artfully connected. For example, landmarks such as the Golden Gate Bridge can be highlighted to a particularly high degree by the Nebei, which regularly occurs in the San Francisco Bay Area.

The device according to the invention for lighting technical accentuation of spatially delimiting spatial structures comprises, in a first preferred embodiment, at least one light source for emitting light and a propagation device for propagating light emitted by the light source in one plane, so that when the light source is actuated, a light source generated by the propagation device and the light plane represented in an optically perceptible manner or a line emerging on the surfaces at least partially delimiting the plane is created by the spreading light.

The light source can be a laser, which is preferably designed as a semiconductor laser that generates a primary laser beam in the visible spectrum or, for special applications, also in the ultraviolet range. The expansion of the laser beam caused by divergence can be minimized by means of collimation optics. This emerging laser beam can also be a combination of several individual colors to generate mixed colors, which are placed on top of one another, for example by means of a dichroic combiner or by means of another laser beam combiner, and fed into the optomechanical device as a simple combined collimated beam. Laser light sources and optics are preferably used here, which generate a beam that is as approximately circular as possible and, in the case of multicolored laser systems, a light beam that is as homogeneous as possible, in which the individual laser beams are superimposed as best as possible and have as identical a diameter as possible and as identical a divergence as possible in order to avoid color overlaps even over longer distances to reduce as much as possible. Correspondingly, further optical and mechanical elements can also be used between a laser light source and a propagation device in order to adapt the characteristics of the beam with regard to the shape of the cross section, as well as diameter, divergence and intensity distribution to the desired effect.

In the context of the present invention, the visible spectrum should preferably be understood to mean a wavelength range between 380 nm and 780 nm, in particular between 405 nm and 670 nm. The ultraviolet range should be understood to mean a wavelength range in the near UV range between 315 nm and 380 nm (“black light”).

In this case, the light propagation device ensures that the essentially linear laser beam is fanned out in a plane which can also be referred to as the light plane.

Depending on the type and structure of the laser light source, its light output can be regulated and its spectral composition can be influenced in a defined manner. The individual colored laser light sources can be switched on and off and dimmed at high frequencies. Accordingly, mixed colors can also be switched and dimmed quickly.

If, in the case of multicolored laser beam sources, usually consisting of the three primary colors red, green and blue, the beams of the individual light sources are offset in such a way that the individual beams of different colors are not exactly congruent, color gradients and effects within one of a light plane generated by a device according to the invention or within a line emerging through this on a surface delimiting it. Such an arrangement of each Laser beams or the beam sources can be static or can be influenced in a defined manner via a controllable mechanism.

Optical perceptibility here means that the respective appearance can be perceived with the naked human eye. The only prerequisite for creating the effect of a luminous plane is the presence of sufficient and suitable suspended particles in the corresponding medium, which can be artificially generated, for example, by a fog machine, and a light source with a correspondingly suitable power depending on the ambient light.

Correspondingly, an optical system and a laser system with such an optical system for lighting technical accentuation of spatial structures that delimit at least some sections are made available.

In an advantageous embodiment it is provided that a laser light source is connected to a propagation device.

The propagation device is, in particular, an optical unit for fanning out the light arriving / impinging on it.

This optical unit comprises at least one optical system which is suitable for fanning out an incident or incident light beam.

In particular, this can be a conical reflector whose tip pointing towards the light source is arranged concentrically in the beam path of the light source and whose base area is orthogonal to the optical axis of the incoming laser beam. In this position, the reflector ensures a deflection of the beam orthogonal to the optical axis of the incoming laser beam, while the conical shape simultaneously fans out the beam by 360 ° circularly to form a plane, provided that it is arranged exactly concentric to the optical axis in the beam path of the incoming light. A slight offset of the reflector from the center of the light beam that can be influenced in a defined manner and with the base area of the circular cone in an orthogonal position to the axis of the incident light can also influence the fanning angle and the direction.

By appropriately spring-loaded mounting of the propagation unit, it can be minimally excited to vibrate, for example by an inductive magnetic field, so that a trembling plane or a trembling line is generated on the surfaces delimiting this at least in sections. As the distance increases, even the smallest movements become very noticeable. For example, with several devices connected to a system in the form of a matrix, as would be the case with a larger window facade, e.g. the tone values of pixels of a video signal can also be expressed in oscillation, which is an interesting effect for media facades or other applications Provides.

The device according to the invention can be connected in terms of control technology to a control device with which, for example, defined signals in music received by the control device can be converted into control commands for actuating the light source.

In this way, the light intensity, the spectral composition and possibly other parameters can be at least partially controlled, for example by music or in a programmed choreography.

Further aspects of the present invention are various systems for lighting technical accentuation of spatially delimiting spatial structures comprising one or more devices according to the invention for lighting technical accentuation of spatially delimiting spatial structures, whereby when several devices are used for lighting technical accentuation of spatially delimiting spatial structures, these are used at a distance from one another.

It is provided that light planes generated by means of a plurality of devices can be essentially parallel and congruent with one another, a simple system for fine adjustment of the respective mounted device being intended. A control of the alignment of the individual devices arranged in a system to one another is possible through the lines generated by the light planes on the surfaces delimiting them, easily and without further measuring tools, with which a high degree of parallelism and congruent alignment can be achieved in an uncomplicated manner. Several devices for lighting technical accentuation of spatially delimiting spatial structures can be operated or arranged in such a way that their propagation devices are congruent and together form a light plane that has a high light intensity and as homogeneous an illumination as possible.

The light levels allow interesting cross-sectional images of the fog to be created and made visible. The indeterminable random shape of the nebula and its ephemeral and immaterial character creates a special and novel effect.

If the light sources of the individual devices have a different light color or a different spectral composition in the case of multicolored light sources, then color gradients can also arise in the area or in the lines emerging on the areas delimiting them.

Several such planes generated by the device according to the invention or the systems according to the invention can also be installed staggered and spaced from one another, so that staggered planes or multi-layer cross-sectional images of the fog arise, which additionally intensifies the effect and its effect.

In further embodiments of the systems it is provided that the systems include a control unit, by means of which light color and intensity and, if necessary, other parameters can be controlled.

The control unit can include respective control devices of the individual devices for lighting technical accentuation of spatially delimiting spatial structures or at least connect them to one another in terms of control technology.

Furthermore, the control unit of the systems can also be set up to convert defined signals, for example in received music or by translating image data or video signals into control commands for actuating the light sources and possibly other elements.

In particular, the control unit can be set up to control light intensity and color as well as other parameters, if necessary, synchronously, out of phase or in a different temporal relation to one another, or to pass these values on to the individual addressable devices or systems by means of control technology by converting a video signal with pixel accuracy.

In particular, if a two-dimensional light effect is desired, floating particles for reflecting and refracting the light and thus for making it visible, but not in sufficient or suitable form, can be generated at the same time, for example fog, so that the respective generated light plane or the sectional images generated by this and unevenly distributed fog become visible.

Thus, according to the invention, a use of the device for lighting technical accentuation of spatially delimiting spatial structures for realizing a system for lighting technical accentuation of spatially delimiting spatial structures is made available.

The ones in the 1A-D illustrated device according to the invention 1 for accentuating spatially delimiting spatial structures, comprises at least one laser light source 10 to generate a laser beam 11 as well as a diffuser 20th to fan out the laser beam 11 to one level 30th .

The propagation device 20th consists essentially of a straight circular cone designed as a reflector 21 . A circular cone is a cone with a circular base. In general, a cone is a geometric body that is created when all points of a bounded surface lying in a plane are connected in a straight line with a point lying outside the plane. The area is referred to as the base area, the boundary line of the base area as the guide curve and the point as the apex of the cone.

The distance between the tip of the cone and the base defines the height of the cone. The connecting lines between the apex of the cone and the guide curve are referred to as the surface lines and the union of the surface lines as the surface of the cone. In the case of a straight cone with a circular base, the cone tip lies on the cone axis, which runs perpendicular to the base through the center thereof, whereas the cone axis extends outside the center of the base in the case of an oblique circular cone.

The surface lines of the circular cone 21 are at 45 ° to its base.

The circular cone 21 is arranged so that its base is orthogonal to the optical axis of the incoming laser beam 11 stands while its tip points in the direction of the incoming laser beam 11 shows.

Is the circular cone 21 concentric to the incoming laser beam 11 arranged, it hits the tip exactly and is at a deflection angle α = 90 ° deflected and all around at an angle of propagation of β = 360 ° to a laser plane 30th fanned out.

The circular cone designed as a reflector 21 is by means of a transparent cylinder 22nd and one about adjusting screws 23 adjustable device in such a way with the laser light source 10 connected that this is on a laser level 30th parallel plane is displaceable. Like in the 1D and the 2A and 2 B shown, the angle of propagation β by shifting from the center of the laser beam 11 set at an angle of less than 360 ° and defined in its direction of propagation, while the entire power of the laser light source 10 focused on the lesser angle.

For a more precise and more acute setting of the angle of propagation β and to create harder edges of the laser plane 30th as well as for the more precise and separately adjustable position of the end points of a laser plane 30th delimiting area resulting from the laser line 31 Individually adjustable lamellae for shading can also be present on the spreading device.

If suitable suspended particles are present in a medium, the laser plane becomes 30th not only as a line on an area that delimits it 31 but also visible as such through refraction and reflection from a suitable viewing angle. In the case of air, this could be, for example, dust or, preferably, fog, which, if it is not present, can easily be generated with a fog machine. Depending on The nature of the fog, which can be specifically defined by controlling the operation of a fog machine and, if necessary, additionally by controlling an exhaust air system or by choosing appropriate fog fluids that differ in their standing times and character, can lead to clearly recognizable clouds of fog, especially in closed rooms 80 or come to a homogeneous distribution in space over time. With a homogeneous haze-like distribution of the fog, the laser plane appears 30th as a predominantly homogeneous, softly glowing surface. On the other hand, there are recognizable wisps of fog 80 present in the air, creates the laser plane 30th like in the 3A and 3B represented by the generation of sectional images 90 of the thick fog 80 an interesting effect. By spaced apart, in particular aligned parallel to one another and possibly multicolored and / or differently colored light planes 30th this effect can be increased.

4th shows a system 4th using an alternative embodiment of a device according to the invention 2 for lighting technical accentuation of a delimiting spatial structure, in which the essential elements of the device, in particular the laser light source 10 and the spreader 20th in front of or behind a transparent pane 41 are appropriate. The laser beam 11 thus penetrates the between light source 10 and propagator 20th lying transparent disc 41 . Such a variant can also offer the above-described possibility of adjustment, by means of which the angle and direction of the expansion can be defined, in order to thus define the length and position of a on a reveal 42 resulting line 31 to be able to influence. The distance of the spreading device 20th to the window, which is mounted on this outside, can be in the height or the distance to the transparent surface 41 the depth of the window frame, for example manually by a rotating mechanism and / or production-related, by choosing appropriate elements of a suitable design. The inclination of the individual elements can also be precisely adjusted to one another by means of further adjusting screws or another possibility of fine adjustment, in order not only to be largely parallel to one another in terms of their alignment, but also to be able to be individually adapted to local conditions.

As in 5 shown, it is thus possible to use the line 31 just in front of the frame, so the line created here 31 , or the reflected light, is predominantly visible from the outside but not strongly visible from the inside. This system therefore offers a simple and inexpensive way of effectively setting the scene for a facade, even if there are no suspended particles in the air. The possible small size of such a device, the low energy consumption and the simple subsequent installation, in which, depending on the variant of the device, not even cables have to be routed to the outside, are advantageous here. The laser plane 30th which outside the window 41 arises, thus creates a line 31 on the entire window reveal 42 . Pixel graphics can also be displayed on a larger facade, especially if the windows are arranged in a dense matrix.

Due to the low energy consumption, this problem can be solved by another, in 6th illustrated application of a system 4th using an alternative device 3 can also be solved by having a complete front of a disc 41 arranged device by means of an induction coil 12th which on the other side of the disc 41 arranged, powered and operated. By means of such a system or such a device, an absolute parallelism of the individual panes that is sometimes not given with insulating glass, which can also change minimally due to thermal factors, and the resulting non-parallel and not easily correctable position of the individual elements of a previously described two-part device are met to each other as far as possible. Here, too, the device can be precisely adjusted in its inclination by means of adjusting screws or another possibility of adjustment, in order to generate a surface or line (s) that is as parallel as possible to the window or wall surfaces.

While these variants are primarily suitable for subsequent installation, such a device can of course also be installed directly in the window frame, on the reveal or with double glazing, as in an alternative in 7th illustrated system 5 using a device 2 , even be arranged in the window. Preferably on the pane facing the interior 41 externally attached laser light source 10 can easily be changed in the event of a defect. Thus is the propagator 20th Dust, airtight and watertight between the panes and protected from external influences. The by the propagation device 20th generated light level 30th is thus located between two panes and runs largely parallel to them, so that there is a line on the web, which is located as a spacer for the panes on the edge of an insulating glazing unit 31 emerging. The character of the line 31 or the radiation of the light can be defined. For example, a phosphor-containing coating can convert the coherent laser light into isotropic radiation and, especially when only one laser light source is used, the monochromatic laser light into one translate wider spectrum. If the spacer bar also has the shape of a wedge, the line generated can thus also be deflected outwards and thus be clearly recognizable from the outside as a clear window border.

Since there is already low power with the corresponding laser protection class with suitable, and in discotheques mostly usual, low basic lighting of the room 50 A device according to the invention can also produce clearly visible effects in or behind passages 54 , as well as in front of ceilings and walls 51 or between pillars 52 or joists 53 , as in 8th and 9 shown, because it prevents a direct view into the concentrated beam and it can also be used as an eye-safe variant due to the already low power and the additionally reduced point power caused by the fanning out. In order to have clearly visible and homogeneously illuminated surfaces despite the low power, several such devices can be used and together create a plane. This increases the overall performance of the system without violating the safety requirements, since a person cannot look in several directions at the same time, and thus the performance directly entering the eye does not increase. This also has the interesting effect that a level 30th person or an object crossing it only partially or not at all visibly shadows and, for example, when reaching in around the entire hand, an unbroken line develops 31 can show what has a science-fiction-like “gate look” that invites the audience to playful interaction. If one uses several appropriately distributed and differently colored or differently colored devices or devices operated differently in terms of control technology, interesting multicolored effects can also arise within the plane when crossing, reaching in or otherwise shading individual light sources forming the plane. 10 shows the application to accentuate a bridge 60 where the bridge arches 61 by a line emerging on this 31 or, if there are corresponding suspended particles, they can be highlighted by making the areas delimited by them visible.

Is a level of light 30th desired, which only arises and disappears in a magical way with appropriate, possibly only temporarily generated, fog and no visible lines 31 generated, this can be limited in a suitable manner and for example end in a gap, or, as in the 11A and 11B and the 12th represented by the use of one made of U-profiles 70 existing framework. the 11A and 11B show a system 6th , in which a device according to the invention by means of filigree elements 71 , such as steel cables, in the middle of one of the U-profiles in this illustration 70 existing spatial frame structure is arranged. The frame serves here at the same time to construct two-dimensional geometric shapes, as well as a light trap for a line emerging in the profile 31 which is therefore not visible even when looking from the side. 12th shows a system 7th consisting of several devices according to the invention, which are directly in the corners of a U-profile in this illustration 70 existing spatial frame structure are embedded. As already described above, in the case of devices of different colors or devices that are set or controlled in different colors, color gradients can thus be created within the plane 30th arise, or with the same light color a lighter and more homogeneously illuminated monochrome plane 30th be generated. Such a frame that delimits a level can basically have any shape and, with the appropriate filigree and colored design, can hardly be noticeable as such in a halfway dark room. In addition to rigid frames and boundaries, flexible variants are also possible in which appropriate straps or rubbers provide the light level 30th limit and the resulting lines 31 hide from direct and lateral view. This enables large, flexible and very cost-effective installations with the least amount of material. Flexible constructions that move through controlled motors or that change their shape are also conceivable.

13th illustrates the possibility of freely hanging frame-bound systems, which can also be referred to as laser panels, in a room 50 .
