    technical field
    The present invention describes a method and a device for simulating the shadow of a person, in particular in the field of burglary protection and / or security technology or the like, according to the preamble of the first and fifth claims.
    State of the art
    Are known from the prior art, various security devices for securing buildings or objects against illegal break-ins or illegal theft. In particular, there are safety devices that prophylactically simulate the presence of people in a building, for example by switching room lighting on and off at predetermined times or by automatic roller shutter controls, in which roller shutters automatically open at daybreak and open at nightfall be moved to the closed position.
    [0003] Document US Pat. No. 5,442,524 also discloses a device for simulating the shadow of a person for improved security and for preventive deterrence of burglars in a private residence or a place of business. This device comprises a central light source and a cylindrical element rotating around the light source, which casts a shadow on a projection surface, e.g. the inner walls of the building, and thus gives the impression of a person moving inside the building.
    In addition, various safety devices are known from the prior art, which are intended to simulate a switched-on TV set using flickering, differently colored light sources such as flickering LEDs.
    Another device for simulating the shadow of a person is known from the document DE 10 2011 084 325 A1 in the field of burglary protection or security technology. The device includes a large number of LED lights for imitating basic lighting, which act as a projector and project an image or a shadow onto a projection surface, in particular in a room. The image can be designed in such a way that it simulates the presence of people or animals. The projected image can be provided on a screen. The device from DE 10 2011 084 325 A1 can also include a loudspeaker for simulating noises made by a person.
    These known security devices have the disadvantage that the simulations obtained do not imitate a person moving in a building very faithfully.
    Presentation of the invention
    The present invention has set itself the task of providing a method for simulating the shadow of a person, especially in the field of burglary protection and / or security technology or the like, and a device for performing the method, with a particularly realistic simulation of a simple way moving person is to be played.
    [0008] These objects are achieved by a method and a device for carrying out the method with the features of patent claims 1 and 5.
    According to the invention, the at least two lamps can be controlled alternately using the controller and can be switched on or off in sequence, so that movements or shadows of a person are simulated. In other words, the at least two light sources connected in sequence can be interpreted as effect lights which are superimposed on a basic lighting.
    According to the present invention, at least one constantly switched-on light source, in particular LED light source, should simulate a switched-on lamp or produce basic lighting.
    Switching on or off in sequence is understood below to mean that the lamps are switched on alternately and in sequence, while an earlier lamp is switched off simultaneously or with a fading effect. The controlled lamps to be switched on can be controlled in a running row or diffusely, i.e. not in sequence.
    [0012] It was advantageously found that the impression of a person moving in a building can be simulated solely by a light source sequence superimposed on the basic lighting. The moving cones of light through the lamps, preferably dimming down or dimming up in a row, simulate such movements.
    The at least two lamps connected in sequence, in particular LED lamps, preferably allow a beam angle of 30° to 120°, more preferably 50° to 90°.
    According to a preferred development, only the basic lighting can be switched on in one setting of the device according to the invention, as a result of which the device only functions as a lamp.
    [0015] Further advantageous embodiments are specified in the dependent patent claims.
    [0016] Preferably, the sequential circuit is designed such that in one setting the at least two lamps can be switched on or off in series to generate a lamp row. This results in short, i.e. not abrupt, transitions between the moving light cones and it is advantageously possible to imitate movements of a person that are as realistic as possible.
    [0017] Even more preferably, the controller is designed in such a way that in each case a subsequent lamp is dimmed up while the previous lamp in the row is dimmed down. As a result, it is advantageously possible to achieve even softer transitions of the lighting means connected in sequence and thus to imitate even more realistic movements of a person.
    Preferably, the inventive device comprises at least one, preferably two, colored such as blue and / or red and / or green LED lamps (preferably RGB LEDs) for simulating a switched-on TV set, preferably with the blue LED lamps allow a beam angle between 30° to 120°, more preferably between 50° to 90°. The control of the device according to the invention is particularly preferably designed in such a way that in one setting the white and blue LED lamps flicker diffusely, i.e. not in series, to simulate a switched-on TV set.
    According to a preferred development, the device according to the invention can include a means for generating a shadow, for example an at least partially opaque, shadow-generating silhouette placed between the lighting means and the projection surface, for example, which can be attached to or integrated into the device. Alternatively or additionally, the device can comprise an at least partially opaque light shaping element placed between the lighting means and the projection surface. The use of such a light-shaping element has the advantage that the theoretically producible light cones of the light sources can be limited and, as a result, in particular the overlapping of the light cones of adjacent light sources can be specifically limited. It has been shown to be advantageous here that the effect of the shadow effects achieved by the light source sequence can be influenced as desired, while with simultaneous operation of all light sources a uniform light pattern (i.e. without strong individual "hotspots") can be achieved corresponding to a constantly switched on lamp without a simulated movement pattern is.
    Preferably, the device comprises a transparent or translucent light-transmitting cover as protection for the light source, i.e. this cover allows the light cone generated by the light source to pass through. Furthermore, it is conceivable that this transparent, translucent cover has, for example, a corrugated structure, thereby functioning as a diffuser plate and additionally scattering the light cone generated by the lamps.
    Furthermore, according to a preferred development, the device according to the invention can comprise a brightness sensor for detecting light sources located outside the device, for example ambient light, for automatic adjustment of the luminous intensity of the LED light sources. As an alternative or in addition to a brightness sensor, a computer of the device according to the invention can be equipped with appropriate software, which adjusts the luminous intensity of the lamps based on the time of day and night.
    The device preferably comprises at least one loudspeaker connected to the computer for simulating noises made by a person. The software stored on the computer is particularly preferably designed in such a way that the noise simulation is matched to a shadow simulation generated at the same time.
    [0023] The device particularly preferably comprises a microphone, the microphone being used to detect noises from third parties. For example, the microphone can be used to generate an acoustic counter-reaction to the noise of third parties.

    description
    1a shows a schematic front view of a preferred embodiment of the device 1 according to the invention. The device comprises an LED printed circuit board 3 which is arranged inside a housing 7. On the LED circuit board 3 are two white LED lamps 4; 4' for generating basic lighting, five white LED lamps 5 arranged in a row; 5'; 5''; 5'''; 5'''' and two blue LED illuminants 6; 6' for generating a TV simulation. The LED lamps used here 4; 4'; 5; 5'; 5''; 5'''; 5''''; 6; 6' are designed to be dimmable. The LED circuit board 3 is arranged here at an angle to a transparent, translucent cover 11 , the cover 11 being integrated directly into the housing 7 . The cover 11 allows the luminous cone of the LED lamps 4; 4'; 5; 5'; 5''; 5'''; 5''''; 6; 6' (see Figures 2a and 2b). Alternatively, it is also conceivable that the LED lighting means 5; 5'; 5''; 5'''; 5'''' can act both for generating the basic lighting and as effect lights (i.e. without additional LED illuminants 4; 4' for generating the basic lighting). Between the circuit board 3 and the cover 11 can also be a light shaping element to limit the light cone of the LED lamps 4; 4'; 5; 5'; 5''; 5'''; 5''''; 6; 6' according to a further preferred embodiment (see Fig. 3a and 3b).
    As indicated by dashed lines, the controller 2 with the LED lamps 4; 4'; 5; 5'; 5''; 5'''; 5''''; 6; 6 'connected to their control or actuation. The controller 2 is in turn connected to a computer 14 (for example Espressif or Raspberry Pi). The computer 14 contains software for operating the controller 2. Using the software stored on the computer 14 and the controller 2, the LED lamps 5; 5'; 5''; 5'''; 5'''' can be controlled alternately using the controller 2 and switched on or off in sequence so that the impression of a moving person is created.
    The device 1 according to the invention can preferably be used as a pure LED lamp in an operating setting, i.e. without constantly switching on or off individual LED lamps.
    The device 1 shown in FIG. 1a also includes, for example, a brightness sensor 16 coupled to the controller 2 to detect light sources located outside the device, for example ambient light, for automatic adjustment of the light intensity of the LED light sources 4; 4'; 5; 5'; 5''; 5'''; 5''''; 6; 6'.
    Furthermore, the device 1 shown in FIG. 1a shows a loudspeaker 15 connected to the computer 14 for simulating the sounds of a person.
    Fig. 1b shows a schematic side view of the preferred embodiment to illustrate an angled LED circuit board 3. Between the plane in which the LED circuit board 3 lies and the plane in which the cover 11 integrated into the housing 7 lies (or the base plane of the device), an angle γ is spanned. For example, an LED light source (not visible in FIG. 1b) on the LED printed circuit board 3 generates a cone of light projected onto a projection surface P (for example an interior wall of a building). As an alternative or in addition, it is also conceivable to angle individual LED illuminants in relation to one another.
    2a shows a sketch of the light cone L1 emerging from the first preferred embodiment of the device according to the invention; L2 on a projection surface P in a first snapshot during the simulation of a moving person using a row of LEDs. In this case, two white, constantly switched-on LED lamps 4', 4'' illuminate an interior of a building with a beam angle β of preferably 30° to 180°, more preferably 60° to 120°, and thereby form basic lighting. The projection surface P is formed by two walls W1 standing at an angle to one another; W2 in an interior of a building. Two of the white LED lamps 5 acting as effect lights; 5'; 5''; 5'''; 5'''' are also switched on here and generate light cones L1; L2 with a radiation angle α of preferably 30° to 120°, more preferably 50° to 90°. For example, the LED illuminant 5'' just dims down here, while the LED illuminant 5''' just dims up to produce an LED running row. An observer B outside the building sees the light cone L2 of the LED illuminant 5''' and a light cone of the LED illuminant 4'' on a wall W2, for example.
    2b shows a sketch of the light cone L2 emerging from the first preferred embodiment of the device 1 according to the invention; L3 on a projection surface P in a later, second snapshot. Here the LED illuminant 5''' is dimming down while the LED illuminant 5'''' is dimming up and creates a new light cone L3. The light cones L2 and L3 move along the wall W2 in the direction of the arrow P, and for the outside observer B the impression of a moving person is created here.
    3a shows a sketch of the light cone L1 emerging from a second preferred embodiment of the device 1 according to the invention; L2 onto a projection surface P in a first snapshot, with the device 1 having an additional light shaping element 12 to limit the theoretically achievable light cone (see FIGS. 2a and 2b) of the LED lamps 4', 5; 5'; 5''; 5''' included. The at least partially opaque light shaping element 12 is here between the LED lamps 4 ', 5; 5'; 5''; 5''' and the projection surface P placed. On the LED printed circuit board 3 there are, for example, a white LED light source 4' for generating basic lighting and four white LED light sources 5 arranged in a row; 5'; 5''; 5''' for generating a LED running row.
    3a shows a section through the light shaping element 12 essentially in the middle through or along the LED illuminants 4', 5; 5'; 5''; 5''' visible. This light-shaping element 12 can be designed, for example, as a deep-drawn plastic part, as indicated here. These deep-drawn sections or depressions 13; 13'; 13'' of the light-shaping element 12 can be understood as funnels, with these funnels being able to have the shape of a right or inclined cone, a tetrahedron or a square or rectangular pyramid, for example. As can be seen in FIG. 3a, the indentations 13; 13'; 13'' at the same time as sockets for the LED lamps 4', 5; 5'; 5''; 5'''.
    A preferred light-shaping element 12 shows, at least in the longest extent shown in FIG. 3a, a symmetrical structure with an axis of symmetry running through the LED illuminant 4'. Furthermore, the depression 13 has an angle γ of preferably between 60° and 140°, very particularly preferably about 120°, at least in the longest extent between two opposite side surfaces. Furthermore, at least in the longest extent of the light-shaping element 12, the depressions 13' between two opposite side surfaces have an angle γ1 of preferably between 10° and 80°, very particularly preferably about 30°. In addition, at least in the longest extent of the light-shaping element 12, the depressions 13'' between two opposite side faces have an angle γ2 of very particularly preferably approximately 44°.
    Preferably, the LED lighting means 4, 5; 5'; 5''; 5''' and the funnel-shaped depressions 13; 13'; 13'' of the light shaping element 12 is dimensioned in such a way that the LED illuminants 5'; 5'', measured crosswise, limited beam angle α1 of preferably 30° to 120°, particularly preferably about 70°, can be achieved, and so that the LED illuminants 5; 5′″, measured crosswise, limited beam angle α2 of preferably 30° to 120°, very particularly preferably about 70°, can be achieved (see FIG. 3b).
    The two white LED lamps 5' acting as effect lights; 5'' are switched on here and generate light cones L1; L2. At the same time, a white, constantly switched-on LED illuminant 4′ illuminates an interior of a building with a limited beam angle β1 of preferably 90° to 180°, particularly preferably around 125°, and thereby forms basic lighting.
    For example, the LED illuminant 5' just dims down here, while the LED illuminant 5'' just dims up to generate an LED running row. A viewer B outside the building sees the light cone L2 of the LED illuminant 5'' and a light cone of the LED illuminant 4' on a wall W2, for example.
    3b shows a sketch of the light cone L2 emerging from the second preferred embodiment of the device 1 according to the invention; L3 on a projection surface P in a later, second snapshot. Here the LED illuminant 5'' just dims down while the LED illuminant 5''' just dims up and creates a new light cone L3. The light cones L2 and L3 move along the wall W2 in the direction of the arrow P, and for the outside observer B the impression of a moving person is created here. It is indicated with reference to FIG. 3b that—compared to FIG. 2b—the overlapping of the light cones L2; L3 is lower. The arrow P is also longer with the light shaping element 12 according to FIG. 3b than without the light shaping element 12 according to FIG. 2b, which indicates a stronger delimitation of the light cone L2; L3 indicates. Furthermore, FIG. 3b can be seen particularly clearly that the to the outer LED lighting means 5; 5''' associated depressions 13'' are open or tilted towards the outer ends in order to achieve the widest possible, almost technically possible beam angle of the LED lamps 5; 5''' corresponding illumination, ie toward wall W2, with an angle y3 between the side surface oriented toward wall W2 and a plane E defined by the LED circuit board 3 preferably being less than 20°, while the opposite side surface is at most perpendicular to plane E.
    Fig. 4 shows a schematic representation of several of the preferred embodiments of the device according to the invention connected to a wireless network environment 21.
    Using an external control device, here by way of example a smartphone 20, the device 1 can be controlled and configured, for example via the Internet and an Internet router 22. A suitable app is preferably installed on the smartphone 20 for this purpose.
    Alternatively or additionally, the device 1 can include a Bluetooth module, whereby the external control device can also be controlled and configured directly with the device.
    [0043]Preferably, each device 1 also includes a manually operable user interface.
