Abstract

This is achieved by superimposing the at least two sequentially switched lamps on the basic lighting.

Description

Device for simulating the shadows and / or sounds of a person

Technical area

The present invention describes a method and a device for simulating shadows and / or for simulating noises 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

From the state of the art, various safety devices are known for securing buildings or objects against unlawful burglaries or illegal abduction. In particular, there are safety devices which prophylactically simulate the presence of persons in a building, for example by switching on and off the lighting of rooms at predetermined times or by automatic roller shutter controls in which shutters automatically at daybreak in an open position and at nightfall in a Closing position are moved. From document US Pat. No. 5,442,524, a device is known for simulating the shadow of a person for improved safety and for the preventive deterrence of burglars to a private residence or a place of business. This device comprises a central light source as well as a cylindrical element rotating around the light source, which project a shadow onto a projection surface, e.g. As the inner walls of the building, and thereby creates the impression of a person moving in the building. In addition, various safety devices are known from the prior art, which are to simulate flickering, different colored light sources such as flickering LEDs a switched TV set.

From the document DE 10 2011 084 325 AI another device for the simulation of shadows of a person is known in the field of burglary protection or security technology. The device comprises a multiplicity of LED lights for imitating a basic illumination, which function as a projector and project an image or a shadow onto a projection surface, in particular in a room. In this case, the image can be designed such that it simulates the presence of persons or animals. The projected image can be provided on a screen. The device of DE 10 2011 084 325 A1 may also comprise a loudspeaker for simulating noises of a person.

These known safety devices have the disadvantage that the simulations achieved do not imitate a person moving in a building very truthfully.

Presentation of the invention

The object of the present invention is to provide a method for simulating shadows of a person, in particular in the field of burglary protection and / or security technology or the like, as well as a device for carrying out the method, wherein in a simple manner a particularly realistic simulation of a person moving should be reproduced. These objects are achieved by a method and an apparatus for carrying out the method with the features of claims 1 and 5. According to the invention, the at least two lighting means can be activated alternately on the basis of the control 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 lamps connected in sequence can be regarded as effect lights, which superimpose a basic illumination.

For the purposes of the present invention, at least one constantly switched on light source, in particular LED light source, is intended to simulate a switched-on lamp or to generate a basic lighting.

Switching on or off in sequence also means that the lighting means are switched on alternately and in succession, while an earlier lighting means is switched off simultaneously or in a blending manner. In this case, the controlled bulbs to be switched in a row or diffuse, d .h. not in turn, be driven. In this case, it has been found advantageous that the impression of a person moving in a building can be simulated solely by means of a light source sequence superimposed on the basic lighting. The wandering light cone through the, preferably diminishing or dimming in series, bulbs simulate such movements. The at least two, connected in sequence, bulbs, in particular LED bulbs, preferably allow a Abstra hel angle of 30 ° to 120 °, more preferably 50 ° to 90 °. According to a preferred development, only the basic lighting can be switched on in a setting of the device according to the invention, as a result of which the device functions merely as a lamp.

Further advantageous embodiments are specified in the dependent claims.

Preferably, the sequence circuit is configured such that, in one setting, the at least two lighting means can be switched on or off in series in order to generate a light source row. This results in short, i. not abrupt, transitions between the wandering cones of light and it can be advantageously imitated most realistic movements of a person.

More preferably, the controller is configured such that in each case a subsequent light source, dimmed up during the dimming down of the preceding in the row light source. As a result, even softer transitions of the lamps connected in sequence can advantageously be achieved, thus imitating 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 bulbs (preferably RGB LEDs) for simulating a switched-TV, preferably the blue LED bulbs between a radiation angle 30 ° to 120 °, more preferably between 50 ° to 90 °. Particularly preferably, the control of the device according to the invention is designed such that in one setting the white and blue LED lights medium diffuse, d .h. not in series, flicker to simulate a switched-TV.

According to a preferred refinement, the device according to the invention can comprise a means for producing a shadow, for example a silhouette placed between illuminants and projection surface and at least partially opaque, producing a shadow, for example attachable or integrated to the device. Alternatively or additionally, the device may 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-emitting means can be limited and, in particular, the coverage of the light cones of adjacent light-emitting means can be specifically limited. It has proved to be advantageous in this case that the effect of the shadow effects achieved by the luminous flux sequence can be influenced as desired, while with simultaneous operation of all luminous means a uniform light image (that is to say without strong individual "hotspots") corresponds to a constantly switched on Lamp without simulated movement pattern is achievable.

Preferably, the device comprises a transparent or translucent translucent cover as protection for the

Illuminants, d .h. this cover allows the light cone of the bulbs to pass through. Furthermore, it is conceivable that this transparent translucent cover, for example, a

Has wave structure, thereby acting as a diffuser plate and additionally scatters the light cone generated by the bulbs.

Furthermore, according to a preferred development, the device according to the invention can comprise a brightness sensor for detecting illuminants located outside the device, For example, ambient light, for automatically adjusting the light intensity of the LED bulbs. 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 adapts the light intensity of the light sources on the basis of the times of day and night.

The device preferably comprises at least one loudspeaker connected to the computer for simulating noises of a person. Most preferably, the software stored on the computer is designed in such a way that the noise simulation is tuned to a simultaneously generated shadow simulation.

Particularly preferably, the device comprises a microphone, wherein the microphone is used for detecting noises of third parties. For example, the microphone can be used to generate an acoustic counter-reaction to the noise of others.
