    Burglary prevention device
    The subject invention relates to a method for imitating a shadow of a shadow-casting object with a security device and the security device itself.
    In order to prevent burglary, the prior art provides for devices to be operated in the absence of people within a building in order to simulate the presence of a person or an animal in order to deter potential burglars. Known are "electronic watch dogs" (e.g. US 4,212,007 A) with proximity sensors that reproduce bell noises or TV simulators (e.g. US 5,252,947 A) that simulate the typical light of a television. TV simulators have the disadvantage of being indirectly related to presence, since it is only assumed that someone is sitting in front of the television.
    Automated switching on and off of light adapted to the 24-hour rhythm of a person is also used, as well as intelligent roller shutter controls combined with motion detectors. A disadvantage of such methods is that their deterrent potential is comparatively low in today's automated time.
    Furthermore, it is known from the patent claims of DE 10 2011 084 325 A1 to use LED projectors in order to project human or animal images onto flat or cylindrical screens. Disadvantages arise from the installation and deinstallation efforts of the screens and the high costs for these and for the LED projectors. Apart from that, direct projections that represent the image of a person or an animal make it easy to see whether it is real or not.
    DE 10 2009 015 466 A1 mentions the generation of light-shadow changes by means of a controllable light source. Moving shadows should also be imitated by controlling the light source. However, apart from the use of a light source with LED lamps, there is no indication of how this goal should be realized.
    The object of the invention is to provide a security device and a method which make it possible to realistically represent and imitate the presence of humans and / or animals in a building using the simplest, least expensive means.
    This object is achieved by a device according to the features of the device and method claims mentioned. The light emitted by the light sources illuminates an illuminated surface evenly. If a group of adjacent light sources is now reduced in intensity compared to the intensity of the emitted light from light sources outside the at least one group, a realistic shadow can be simulated on the illuminated surface in a very simple manner, whereby a shadow effect can be generated in a simple manner. The summary of side by side1 / 27 1
    EO-7527 AT neten light sources also make it possible to regulate these together in intensity, which makes it easier to control the light sources.
    A dynamic shadow can be generated very easily if further light sources are added to the at least one group and / or light sources of the at least one group are removed from it and the intensity of the emitted light from an added light source is reduced and the intensity of a removed light source is increased. This makes it easy to simulate effects such as a movement of the shadow, a shadow that grows or shrinks, or a shadow created by a candle. This enables particularly realistic shadow simulations.
    The control of the safety device can be considerably simplified if a matrix-like arrangement consists of a plurality of columns of light sources and a plurality of rows of light sources, and all the light sources of a column are assigned to the at least one group.
    The shadow can be simulated even more realistically if the intensity of the emitted light from the light sources of the at least one group is controlled according to a bell curve, one or more light sources in the center of the group emitting the lowest intensity and the intensity of the emitted light from the subsequent light sources increases according to the bell curve. In this way, hard transitions at the border of the simulated shadow can be avoided.
    The control can also be simplified if several light sources of the group are controlled together and in the same way in the intensity of the emitted light.
    The flexibility of the security device in the possibilities of shadow simulation can be increased if all light sources of the group are controlled individually and independently of one another in the intensity of the emitted light.
    A simple adaptation to existing room lighting is possible if the light color of at least one light source of the arrangement, preferably all light sources of the arrangement, is additionally controlled.
    Another or additional possibility of influencing the emitted light of the safety device is the use of an optical element for a light source or a group of light sources. The light emitted by the light source or the group of light sources can thus be bundled or scattered in a simple manner.
    If the optical element is made of intelligent glass, the intensity of the emitted light can also be influenced via the optical element.

    The invention is based on research that reflects the typical scenarios of an inhabited house that are visible from the outside. Coupled with the need for a realistic representation in order to provide a high deterrent potential, images in shadow form have proven to be ideal.
    In order to achieve realistic effects, the device consists of a light source that is designed in type and property in such a way that, in contrast to LED projectors, it generates a pleasant, warm light that differs in intensity and light color from conventional light sources. that are used for room or ambient lighting hardly differ.
    The research also showed that typical shadows are, with a high degree of probability, not 1: 1 images of people, animals or objects, but consist of random patterns, the appearance of which is shaped by reflection and absorption of the emitted light. The edges of a shadow, e.g. When a person and / or animal passes through the light beam of a typical light source in a building, it is in most cases blurred on walls, furnishings and / or objects. This effect is based on the fact that most lighting fixtures do not consist of singular point light sources, but are built up over a large area or are composed of several light sources and usually have a high radiation angle, for example of 120 °. A light from such sources strikes the shadow-casting object from different directions and thus creates several overlapping shadow images with blurred edges.
    The present invention makes use of these findings and forms the described appearances through an arrangement of individual light sources that can be controlled in intensity, / 27
    EO-7527 AT, preferably with an optical element in front of it, as described in the device claims, realistically so that the viewer, for example looking through a window from the outside, can see no difference from reality.
    Even with a long and detailed view of the shadow images from the outside, it is difficult to distinguish between reality and simulation due to the sophisticated algorithm described in the process claims.
    There are various design and electrical versions of the safety device to simulate movements of people and / or animals, as described below.
    The safety device 1 is shown in an advantageous embodiment in FIGS. 1 and 2 and comprises a housing 10 in which an arrangement 13, preferably a matrix-shaped arrangement, of a plurality of light sources 2 is arranged, the light sources 2 being next to and above one another (also offset from each other) are arranged. A matrix-like arrangement 13 of light sources 2 consists of a number of rows of light sources 2 lying next to one another, a number of light sources 2 being provided in each row. The same number of light sources 2 need not be provided in each row. Adjacent rows do not always have to be the same distance and the distance between adjacent rows can also vary within the rows. Adjacent light sources 2 in a row do not always have to be at the same distance from one another. In a uniform arrangement (as shown in FIG. 2), the matrix-shaped arrangement 13 of light sources 2 is formed by a number of rows lying next to one another and a number of columns of light sources 2 lying next to one another. The light sources 2 of a row and a column in the uniform arrangement are preferably also regularly spaced apart.
    The housing 10 is of course transparent in the area of the arrangement 13 of light sources 2 so that light can be emitted by the safety device 1. One side surface of the housing 10 is preferably transparent. In the context of the invention, a transparent area 11 is understood in particular to mean a translucent area and also an embodiment where the housing 10 is cut out in the area of the arrangement 13 of light sources 2. Individuals or groups of light sources 2, for example an entire column of light sources 2, can be assigned an optical element 12, for example an optical lens 4 or a lens system, in order to bundle or to bundle the emitted light from a light source 2 or the group of light sources 2 sprinkle. In a particularly advantageous embodiment, the transparent region 11 is at least partially designed as an optical element 12. In a particularly advantageous embodiment, each light source 2 has its own optical element 12.

    Monochrome SMD LEDs with a high luminous efficacy and low power consumption are mainly used as the light source 2. Usually warm light sources (light color typically 2700K) are used which emit a pleasant light. Of course, other types of light sources 2, also with different light colors and light characteristics, can be used.
    Alternatively, multicolored LEDs in all forms (e.g. RGB, RGBW, wired or SMD) can be used as light source 2. Multi-colored LEDs have the advantage that you can adapt to the light color of the light sources already in the building and therefore meet the highest simulation requirements.
    LEDs, or general light sources 2, with a built-in lens as optical element 12 are also an alternative.
    The preferred aim of the safety device 1 is to direct the light from the light sources 2 (LEDs) onto the illuminated surfaces in such a way that uniformly homogeneous illumination is achieved on the one hand, but on the other hand individual areas of the illuminated surface are soft (= no hard transitions between the Areas) can be hidden. For this purpose, the light sources are preferably arranged such that the light emitted by the individual light sources 2 overlaps at least partially at a certain distance from the safety device 1, which enables uniform, homogeneous illumination.
    In an exemplary variant, e.g. 12 * 5 LEDs (as a concrete example a light source 2) mounted on the outer surface of a cylinder with a radius of about 10cm and a height of 5cm so that 12 LEDs in a row next to each other horizontally on a e.g.
    100 ° sector of the cylinder and 5 LEDs in each column can be placed vertically one below the other in a matrix-shaped arrangement 13 of light sources 2, as shown in FIG. The radiation angle of each LED without optical element 12 is approximately 120 ° for the assumed LEDs. In front of each LED column 3 there is an optical lens 4 e.g. a concave-convex cylindrical lens system (only indicated in Fig. 2), which shifts the light of each LED column 3 vertically only in parallel and therefore lets it through unaffected and reduces it horizontally to about 30 ° radiation. This results in a total radiation of 120 ° vertically and approximately 130 ° (100 ° sector + 2 x 30 ° / 2) horizontally (see Fig.3a and 3b). The optical system is designed in such a way that the environment at the relevant points in the room is evenly illuminated up to a certain distance (e.g. 4m) when all LEDs emit with the same intensity, since the light from the 12 LEDs is reflected in the illuminated areas overlapping the distance over a large area.
    In a further variant, e.g. 12 * 5 LEDs (as a concrete example a light source
    2) on a sector of the surface of a sphere with a radius of about 10cm or a Rotati5 /
    EO-7527 AT onsellipsoid mounted in such a way that 12 LEDs side by side horizontally in a row on a e.g. 100 ° sector and 5 LEDs each vertically in a column on a sector of e.g. 40 ° degrees in a matrix arrangement 13 place. The radiation angle of each LED without an optical system is about 120 ° degrees with the assumed LEDs. In front of each LED there is e.g. a concave-convex lens that measures the beam angle of each LED both vertically and horizontally depending on the distance between the LED and the wall, e.g. 30 degrees reduced. This system can also be used to implement shadow effects in the vertical direction.
    Of course, designs with different radiation angles or arrangements of the light sources 2 are also possible. Alternative designs can have more or less curved fronts and have arrangements 13 adapted to different rooms. A 360 ° version for all-round lighting and simulation is also a variant.
    In a special variant, it is also possible to design an optical element 12 in front of a light source 2 such that it can not only deflect or deflect the emitted light, but can also modulate the intensity of the penetrating light. An optical element 12 could, for example, be made of intelligent glass in order to take over the intensity modulation which is advantageous for realistic shadows. Intelligent glass refers to materials whose light transmission can be changed by applying an electrical voltage or by heating.
    All of the above solutions have the advantage that devices with high resolution can be dispensed with. The bundling of light by means of an image projecting medium, which is necessary in conventional projectors, is also eliminated, with the result that a strongly light-damping part can be avoided and the safety device 1 can be made more energy efficient.
    Energy-efficient versions can also be operated without a fan. As a result, the safety device 1 is additionally silent in this form.
    In order to simulate shadows with the arrangement 13 of light sources 2, at least one group 5a consisting of a plurality of adjacent light sources 2 is reduced in the intensity of the emitted light. The remaining light sources 2 of the arrangement 13, or at least some of them, continue to emit light with a higher intensity. “Neighboring light sources 2” are understood to mean light sources 2 which are arranged in the arrangement 13 directly next to or above one another, also obliquely next to or above one another and also offset. This is shown by way of example in FIG. 4 for an irregular matrix-shaped arrangement 13 with four rows Rn, n = 4 and in each case a number of light sources 2 in each of the rows Rn. 5 shows a regular matrix arrangement 13 with five rows Rn, n = 5 and seven columns Sm, m = 7. In each row Rn a light source 2 is arranged in each column Sm, thus seven light sources 2 in each row Rn. In this version, / 27 6
    EO-7527 AT, for example, two groups 5a, 5b of adjacent light sources 2 are provided for shadow simulation. This allows two shadows to be simulated on the illuminated area. Of course, a group 5a, 5b can also comprise a line-shaped or ring-shaped, generally any, arrangement of light sources 2 in order to generate different shadow shapes.
    The light sources 2 of a group 5a, 5b can be controlled individually and independently of one another or together in the intensity of the emitted light. In any case, the light sources of a group 5a, 5b can be regulated independently and separately from the light sources outside of group 5a, 5b in the intensity of the emitted light. The intensity of the emitted light from the light sources 2 of the group 5a, 5b can thus be reduced and the intensity of the emitted light from the remaining light sources can be emitted with a higher intensity independently of this. The intensity of the emitted light within a group 5a, 5b does not of course have to be the same, which is possible with individual control. Even outside of group 5a, 5b, the intensity of the light emitted by the light sources outside of group 5a, 5b need not be the same, but this will normally be the case.
    In the simplest embodiment, a group 5a, 5b of adjacent light sources of different rows Rn of light sources 2 arranged one above the other, for example the light sources 2 of a column Sm, of the arrangement 13 in FIG. 5, is formed. In this embodiment, it can also be provided in terms of circuitry that all light sources 2 of a column Sm can only be regulated together in intensity. A group 5a, 5b then comprises at least all light sources 2 of a column Sm.
    The assignment of the light sources 2 to a group 5a, 5b can also change during the operation of the safety device 1. It can be used to simulate effects such as multiple shadows, moving shadows or shadows of different sizes. For several shadows, for example, several groups 5a, 5b are defined and the intensity of the emitted light of the light sources 2 located in the groups 5a, 5b is reduced compared to light sources 2 except for the groups 5a, 5b. For moving shadows, light sources 2 are added to a group 5a, 5b and / or light sources 2 are removed from a group 5a, 5b. The added light sources 2 are of course reduced in intensity and the removed light sources are increased in intensity. Depending on which light sources 2 are added or removed, the shadow can move in different directions. This means that movements such as Bending down, sitting down or jumping are simulated. By adding light sources 2 to a group 5a, 5b and / or removing light sources from a group 5a, 5b, a shadow that becomes larger or smaller can also be simulated as a moving shadow. These options can of course be combined as desired.
    / 27 1 '
    EO-7527 AT
    To control the intensity of the emitted light, the supply voltage or the supply current of a light source 2 can be changed by a control unit 7 and / or the light transmission of an optical element 12 can also be changed.
    Control units 7 with processors, such as, for example, serve as the basis for the controls of the light sources 2 (LEDs). ATMEL 328P or more powerful models, depending on the equipment of the safety device 1, which, for example, control multiplex-free LED drivers in order to avoid unrealistic flickering. In the case of a multiplex-free driver, the desired intensity of a light source 2 remains set, for example a light source 2 remains switched on and is not switched on and off at a high frequency. The control unit 7 can be integrated in the safety device 1, but can also be external.
    Most models of the safety device 1 are operated with external switching power supplies and voltages <24V, but of course integrated power supplies are also possible.
    For perfect integration into the environment to be protected and to enable interactions, the security device 1 can provide electronic interfaces in order to be able to receive commands as well as to be able to take actions. In this way, two or more safety devices can be coupled together through the respective interfaces in order to simulate shadow movements across rooms or across floors. Preferred forms of transport for this type of communication are LAN / WLAN or Bluetooth in all variants. But also other common data transmission options, such as Use of the so-called ISM tapes, which are available for domestic areas, are conceivable. In the future, LiFi (= Light Fidelity) interfaces could also be available. In the simplest version of the interfaces, a socket with a potential-free contact is available for the output, which is compatible with any modern alarm system and as an input a socket with a pull-up or pull-down circuit behind it, which accepts the commands by setting them to zero. (GND) or supply (Vcc) potential. By using encodings in the form of protocols, a single input can possibly accept several commands at once.
    This enables the integration of motion sensors to generate shadows exactly when a person is approaching. Of course, an algorithm preferably prevents the exact repetition when reactivated.
    The activation and control of the safety device 1 can be triggered by versatile possibilities of external components, autonomously automatically or manually.
    In automatic mode e.g. a light sensor can also take over the activation.
    / 27 8
    EO-7527 AT
    After activation of the safety device 1, the light sources 2 of a group 5a, 5b of light sources 2, for example individual columns 3 and / or individual light sources 2 (LEDs) in the arrangement 13, are controlled in accordance with the implemented control such that shadows, preferably moving shadows, arise and the shadow generation intervals remain realistic.
    A UPS (uninterruptible power supply) can also be connected to the security device 1, in order to automatically switch to a candlelight mode in the event of a power failure after a short time, in which the light source 2 is modulated by candlelight type, in order to ensure that any burglars, especially in this case, are present simulate.
    As a special extension, network functions (e.g. routers) could also be offered in the device. This combination saves space and the safety device 1 can be perfectly integrated into a possibly existing network.
    In a further alternative, the mechanisms of the security device 1 can be influenced in various forms if, for example, an app is used for Android or iOS devices. It can then e.g. simply parameterize processes or create schedules and triggers for activation
    Additions with other functions such as clock, radio, disco light, peak meter for real time, frequency spectrum visualization or controllable lighting from 0-360 ° degrees are also conceivable.
    The safety device 1 is preferably placed in a room 20 on a flat, horizontal surface or hung on the ceiling or wall and aligned with the transparent area 11 on a wall 21 which is visible from the outside through a window 22 or a patio door or the like (Figure 6). The distance and position to the wall 21 is preferably selected such that the entire wall surface visible from the outside is evenly illuminated by the safety device 1. This distance naturally depends on the radiation angles of the individual light sources 2 and can be specified, or can be found out simply by trying it out. A shadow 24 is then created and simulated on the wall 21, which is perceived from outside through the window 22. Of course, other locations and locations are also possible.
    Alternatively, the safety device can also be aligned as a wall 21 on an opaque but weakly light-permeable curtain 23 (FIG. 7) or on a closed louvre roller blind which, by design, allows a few light rays to pass through, as long as direct eye contact from the outside of the safety device 1 is avoided , The shadow 24 is generated and simulated on the curtain 23 or on the slatted roller blind as a wall 21. This variant brings out (simulated) movements particularly well, since the shadows are very well visible from the outside and can also be seen from great distances
    -9 · / 27
    EO-7527 AT den. Furthermore, this arrangement is particularly interesting in combination with an electric slatted blind system with which an interactive reaction to their presence can be played to a person approaching from the outside. This variant is described in the simulation options.
    In general, there are several options available for all applications, depending on the version with or without external inputs. A "manual mode" enables e.g. the operation of the safety device 1 on a simple timer. An "automatic mode" simulates e.g. the scenarios according to preset algorithms. If the safety device 1 is additionally provided with inputs and / or with outputs, it can respond to external influences, such as react particularly realistically to a person's approach to a sensor or trigger additional safety devices 1.
    Assuming that the safety device 1 is aligned with a wall 21, for example the inside of a closed louvre blind or an opaque but translucent curtain 23, and the shadows 24 are viewed from outside through the window 22, e.g. following situations can be simulated simultaneously or separately.
    • Switching the light on and off in the room • Movement in the horizontal direction from left to right or vice versa • Movement along the beam propagation (e.g. in the direction of the slatted blind) or in the opposite direction • Movement in the vertical direction, especially by different heights of the light sources or Objects, or e.g. to be able to simulate the bending of people • Movement of one or more people and / or animals.
    • Movements across several rooms or floors when using multiple safety devices 1 • Another impressive variant is the simulation of all the previously described movements in candlelight. This variant is ideal for burglary prevention in combination with an uninterruptible power supply. In this case, the safety device 1 detects the power failure, switches off the light briefly, and then starts the candlelight mode via the uninterruptible power supply.
    • In a further alternative, the mechanisms of the security device 1 can be influenced in a wide variety of forms if an associated app is used for Android or iOS devices. It can then e.g. Processes are parameterized or schedules and triggers are created for activation.

    EO-7527 AT
    The following are descriptions of algorithms that are responsible for the automatic scene compilation.
    There are several ways to create silhouettes. In the simplest variant, for example, the direction of movement, speed and possibly also other parameters such as acceleration and size of the shadow-casting object are determined by random mechanisms and transmitted to at least one group 5a, 5b of light sources. However, this method has the disadvantage that paths and objects in motion and nature cannot be adapted to situations, or only very slightly. So it is e.g. it is difficult to have a virtual person go to the window and stop there if a motion detector registers an approaching person.
    In a further possibility, several movement scenarios or other necessary parameters of the shadow simulation are precalculated or created in advance and the parameters required for controlling the light sources 2, for example the at least one group 5a, are stored in a table, for example in a memory of the safety device 1 If necessary, the content of the table is read out and played via the arrangement 13 of the light sources 2 of the safety device 1. This method saves a lot of processor power, but also has the disadvantage that the generated shadows can only be controlled interactively to a limited extent.
    Another variant enables the arrangement 13 of the light sources 2 to be controlled externally. For this purpose, for example, the parameters necessary for the shadow simulation or movement scenarios are generated outside of the safety device 1 by external computers, and also, for example, by mobile devices, such as smartphones, and, if necessary, to the safety device 1 transmitted where the arrangement 13 of the light sources 2 is controlled accordingly.
    In order to implement realistic shadow images, however, a shadow-casting object 8 is preferably assumed in the room 20 and the security device 1, for example in the control unit 7, calculates which shadow 24 is generated by this shadow-casting object 8 on the wall 21. For this purpose, parameters can be used internally, which describe the nature (e.g. size, shape, etc.) and movements of the desired shadow-casting object 8 to be displayed. The control of the safety device 1 then converts the settings into shadow movements, which are implemented by correspondingly controlling the light sources 2. For this purpose, at least one group 5a, 5b of light sources, which are required for the shadow generation, are controlled in order to lower their intensity of the emitted light compared to the light sources 2 outside the at least one group 5a, 5b. Certain light sources 2 are used to generate a shadow 24
    EO-7527 AT of the safety device 1 is switched off, or in general its intensity is reduced compared to other light sources 2 which illuminate the wall 21.
    Depending on the design of the safety device 1, the parameters can also be influenced or parameterized externally. The number of available parameters depends on the specific design of the safety device 1.
    When the safety device 1 is activated, new scenes for the shadows 24 are preferably continuously calculated. Each scene can consist of the start and end position of the shadow-casting object 8 and the desired acceleration, start and / or end speed and deceleration, and the start and end position can also be the same in order to simulate a stationary object 8.
    The following can serve as parameters for the algorithms for simulating shadow casting:
    The definition of the shape of the shadow-casting object 8. Here, for example, several shapes can be stored and selected. The shapes can also be chosen at random and can also be changed automatically or manually.
    A maximum horizontal radiation angle α of the safety device 1. The maximum radiation angle depends on the physical nature of the optics of the safety device 1, as described above. In most variants it will be around 100 degrees. A maximum vertical beam angle could also be parameterized.
    The position of the shadow-casting object 8 in the space 20 can be indicated by the angle γ and length L of a vector 9 relative to the safety device 1. The vector 9 preferably runs horizontally to the safety device 1. A possible parameterization of the angle could, for example, include an angular range of 0-110 °, 0-4 ° for links outside the physically possible light cone, 5-105 ° representing a 100 ° light cone and 106-110 ° stands for right outside the light cone. The length L can e.g. as a value between 0-250, which can stand for 0-500cm. 0 means e.g. no light, since the shadow-casting object 8 stands in front of the light source 2 and 255 means the smallest shadow, since the shadow-casting object 8 is the furthest away from the light source 2.
    A mounting height H of the safety device 1 defines the height H relative to the light source 2. The height of the light source 2 in the room 20 has a direct influence on the shadow images that can be seen on the wall 21. For example, ceiling lamps for one person in room 20 are more likely to produce lower images than table lamps for the same person. This parameter takes this influence into account when generating shadows and / 27
    EO-7527 AT automatically calculated based on position parameters. The mounting height H can be defined as a value between 0-255, which can stand for a height of 0-255cm.
    The size of the shadow-casting object 8 influences the size of the shadow 24. With the same set or calculated distance of the shadow-casting object 8 from the safety device 1, a larger shadow 24 is generated if the parameter is chosen larger. For a large shadow, more light sources will be contained in the at least one group 5a, 5b than for a smaller shadow. In this way you can also adjust the shadow size to the room size. Thus, in a smaller room 20, larger shadows will be chosen because the shadows 24 would also be smaller due to the short distance to the next imaging surface, whereby the shadows 24 can be selected smaller in larger rooms, since they are anyway due to the distance to the next imaging surface are big enough. The size can be characterized, for example, by 0: small, 1: medium, 2: large. The size can also be changed dynamically. If the safety device 1 is activated, the size is calculated according to the current scene. Should e.g. fictitiously remove the object 8 from the safety device 1, the shadow 24 to be imaged becomes smaller over the way. The size could be changed dynamically in small steps to bring this effect to bear.
    A starting position A and an ending position B can be defined, for example, by a respective vector 9. Likewise, a trajectory of the movement of the shadow-casting object 8 from the start position A to the end position B can be defined. A speed parameter for the movement from start position A to end position B can define how fast the object 8 is to move from the start position A to the end position B. The speed can be specified as a value in cm per second. The value 0 can also not be used for any movement. The safety device 1 then independently generates shadow 24 for a shadow-casting object 8, which, as parameterized, moves from the starting position A to the end position B at the specified speed in order to get from A to B. The shadow 24 is recalculated at specific, predetermined times and set by the activation of the light sources 2.
    The number of objects 8 in the room can also be defined. The presence of several people can thus be simulated. Of course, each individual object 8, including its movement, can of course be parameterized independently of one another.
    Acceleration of the object 8 can indicate how quickly the object 8 accelerates or decelerates when it changes its speed. It can be used to simulate people who are moving slowly or quickly. When entering the light cone you can e.g. assume a uniform movement. For example, this could be 0: Equal / 27
    EO-7527 AT-shaped movement, 1: low acceleration, 2: high acceleration must be defined, whereby of course an acceleration value is stored for the individual stages.
    A number of permanent objects can also be defined. With this e.g. an object can be simulated, which stands between the light source 2 and the window 22, e.g. the rod of a floor lamp that casts shadows.
    The type of light source can be reserved, for example, via the parameters 0: normal light for normal room lighting, 1: candlelight simulation by intensity and position modulation of the shadow 24, 2-255, e.g. Color temperature, etc. This allows the light of the safety device 1 to be adapted to other existing light sources 2 in order to further reduce the difference between real and simulated lighting.
    A parameter number of connected safety devices can define the number of safety devices 1 that can take over the movement of the shadow-casting object 8 from one safety device 1 to another. This is used, for example, for cross-room simulation, in which the object 8 changes from one room and / or one floor to another room / floor.
    Of course, other or additional parameters are also conceivable in order to generate and simulate a shadow 24.
    The calculation of the shadow 24 for a shadow-casting object 8 at a specific point in time, which is at a specific position in space 20 at this point in time, can be carried out using simple vector calculations and simple kinematic relationships. Only low computing power of the control is required for this, which also helps to keep the safety device 1 simple.
    The shadow 24 can also be calculated with an intensity distribution so that there are no abrupt jumps in intensity, which would be unrealistic for a shadow 24. For this purpose it can be provided to change the intensity of the light sources 2 involved in the generation of the shadow 24 in the at least one group 5a, 5b according to a bell curve, for example a Gaussian function. The lowest intensity is of course provided in the center of the shadow 24 and the intensity increases towards the edge of the shadow 24 in accordance with the defined bell curve. The intensity distribution can also be defined separately in the horizontal and vertical directions, and also in any other direction. If a movement of the shadow-casting object 8 is also simulated, the shadow 24, which is adjusted in intensity according to the bell curve, also moves in the horizontal direction and / or in the vertical direction, or in any other direction.
    / 27
    EO-7527 AT
    It is also advantageous if the intensity of the light sources 2 is not changed abruptly, but continuously, or in such small intensity levels that a jerky and flicker-free shadow 24 is created.
    If candlelight is simulated, the shadow 24 can be moved back and forth with the typical candlelight flicker frequency, preferably in the horizontal direction. The lighting of the candle can be simulated by initially increasing the shadow 24 and then reducing it to the normal size according to the position of the shadow-casting object 8.
    The creation of the shadow 24 should preferably not be repeated, or at least not repeated too often or in too short a time period. For this purpose, the position and / or the movement of the shadow-casting object 8 or of the shadow-casting objects 8 can be chosen at random.
    Of course, combinations of the above-mentioned variants of shadow simulation are also possible. The various options for shadow simulation have in common that at certain, predetermined times, a new shadow scenario is generated by the safety device 1 by controlling the arrangement 13 of the light sources 2. In particular, the intensity of light sources 2 can be changed, light sources 2 can be removed and / or added from a group 5a, 5b, groups 5a, 5b can be created or removed and / or other shadow effects can be generated.
