DETAILED DESCRIPTION

[0031] FIG. 1A shows a schematic front view of a preferred embodiment of the device 1 according to the invention. The device comprises an LED circuit board 3, which is arranged inside a housing 7. Here, by way of example, two white LED lamps 4; 4 for creating basic lighting, five white LED lamps 5; 5; 5; 5; 5 arranged in a row and also two blue LED lamps 6; 6 for creating a TV simulation are arranged on the LED circuit board 3. The LED lamps 4; 4; 5; 5; 5; 5; 5; 6; 6 used here are configured in a dimmable manner. The LED circuit board 3 is here arranged in an angled manner with respect to a transparent light-permeable cover 11, wherein the cover 11 is integrated directly into the housing 7. Here, the cover 11 allows the light cones of the LED lamps 4; 4; 5; 5; 5; 5; 5; 6; 6 to pass (cf. FIGS. 2A and 2B). Alternatively, it is also conceivable that the LED lamps 5; 5; 5; 5; 5 arranged in a row can function both for creating the basic lighting and as effect lights (i.e. without additional LED lamps 4; 4 for creating the basic lighting). According to a further preferred embodiment (cf. FIGS. 3A and 3B), a light-shaping element may additionally be arranged between the circuit board 3 and the cover 11 for delimiting the light cones of the LED lamps 4; 4; 5; 5; 5; 5; 5; 6; 6.

[0032] As indicated dashed, the control 2 is connected to the LED lamps 4; 4; 5; 5; 5; 5; 5; 6; 6 for the activation or actuation thereof. The control 2 is in turn connected to a computer 14 (for example Espressif or Raspberry Pi). The computer 14 contains software for actuating the control 2. On the basis of the software stored on the computer 14 and the control 2, the LED lamps 5; 5; 5; 5; 5 functioning as effect lights can be activated in such an alternating manner on the basis of the control 2 and switched on or switched off in sequence, so that the impression of a moving person is created.

[0033] Preferably, the device 1 according to the invention can be used in an operating setting as a pure LED lamp, i.e. without constant switching on or switching off of individual LED lamps.

[0034] Here, by way of example, the device 1 shown in FIG. 1A additionally comprises a brightness sensor 16 coupled to the control 2, for detecting lamps located outside the device, for example ambient light, for automatically adapting the light intensity of the LED lamps 4; 4; 5; 5; 5; 5; 5; 6; 6.

[0035] Furthermore, the device 1 shown in FIG. 1A shows a loudspeaker 15 connected to the computer 14 for simulating noises of a person.

[0036] FIG. 1B shows a schematic side view of the preferred embodiment for illustrating an angled LED circuit board 3. An angle is spanned 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 datum plane of the device). For example, an LED lamp (not visible in FIG. 1B) on the LED circuit board 3 creates a light cone projected onto a projection surface P (for example an interior wall of a building). Alternatively or additionally, it is also conceivable to angle individual LED lamps with respect to one another.

[0037] FIG. 2A shows a sketch of the light cones L1; L2 exiting from the first preferred embodiment of the device according to the invention onto a projection surface P in a first snapshot during the simulation of a moving person on the basis of an LED sequence. Here, two white, constantly switched-on LED lamps 4, 4 illuminate an interior of a building with a beam angle of preferably 30 to 180, more preferably 60 to 120, and form basic lighting as a result. Two walls W1; W2, which are angled with respect to one another, in an interior of a building form the projection surface P. Two of the white LED lamps 5; 5; 5; 5; 5 functioning as effect lights are likewise switched on here and create light cones L1; L2 with a beam angle of preferably 30 to 120, more preferably 50 to 90. For example, here the LED lamp 5 dims straight down, whilst the LED lamp 5 dims straight up to create an LED sequence. An observer B outside the building for example sees the light cone L2 of the LED lamp 5 and a light cone of the LED lamp 4 on a wall W2.

[0038] FIG. 2B shows a sketch of the light cones L2; L3 exiting from the first preferred embodiment of the device 1 according to the invention onto a projection surface P in a later, second snapshot. Here, the LED lamp 5 dims straight down, whilst the LED lamp 5 dims straight up and creates a new light cone L3. In this case, the light cones L2 and L3 travel on the wall W2 in arrow direction P and the impression of a moving person is created here for the external observer B.

[0039] FIG. 3A shows a sketch of the light cones L1; L2 exiting from a second preferred embodiment of the device 1 according to the invention onto a projection surface P in a first snapshot, wherein the device 1 here comprises an additional light-shaping element 12 for delimiting the light cones, which can theoretically be achieved (cf. FIGS. 2A and 2B) of the LED lamps 4, 5; 5; 5; 5. The at least partially non-light-permeable light-shaping element 12 is here placed between the LED lamps 4, 5; 5; 5; 5 and the projection surface P. Here, by way of example, one white LED lamp 4 for creating basic lighting and also four white LED lamps 5; 5; 5; 5 arranged in a row for creating an LED sequence are arranged on the LED circuit board 3.

[0040] A section through the light-shaping element 12, essentially centrally through or along the LED lamps 4, 5; 5; 5; 5, which are arranged in a row here, can be seen in FIG. 3A. As indicated here for example, this light-shaping element 12 can be constructed as a deep-drawn plastic part. These deep-drawn sections or depressions 13; 13; 13 of the light-shaping element 12 can here be understood as funnels, wherein these funnels can for example have the shape of a straight or oblique cone, a tetrahedron or a square or rectangular pyramid. As can be seen in FIG. 3A, the depressions 13; 13; 13 are simultaneously used as sockets for the LED lamps 4; 5; 5; 5; 5.

[0041] A preferred light-shaping element 12, at least in the longest extent shown in FIG. 3A, shows a symmetrical structure with an axis of symmetry running through the LED lamp 4. Furthermore, the depression 13, at least in the longest extent, has an angle 1 between two opposite side surfaces of preferably between 60 and 140, very particularly preferably approximately 120. Furthermore, the depressions 13, at least in the longest extent of the light-shaping element 12, have an angle between two opposite side surfaces of preferably between 10 and 80, very particularly preferably approximately 30. In addition, the depressions 13, at least in the longest extent of the light-shaping element 12, have an angle 2 between two opposite side surfaces of very particularly preferably approximately 44.

[0042] Preferably, the LED lamps 4, 5; 5; 5; 5 and the funnel-shaped depressions 13; 13; 13 of the light-shaping element 12 are dimensioned in such a manner that the delimited beam angle 1, measured crosswise across the LED lamps 5; 5 mounted in the depressions 13, of preferably 30 to 120, very particularly preferably approximately 70, can be achieved, and that the delimited beam angle 2, measured crosswise across the LED lamps 5; 5 mounted in the depressions 13, of preferably 30 to 120, very particularly preferably approximately 70 can be achieved (cf. FIG. 3B).

[0043] The two white LED lamps 5; 5 functioning as effect lights are switched on here and create light cones L1; L2. At the same time, a white, constantly switched-on LED lamp 4 illuminates an interior of a building with a delimited beam angle 1 of preferably 90 to 180, very particularly preferably approximately 125, and forms basic lighting as a result.

[0044] For example, here the LED lamp 5 dims straight down, whilst the LED lamp 5 dims straight up to create an LED sequence. An observer B outside the building for example sees the light cone L2 of the LED lamp 5 and a light cone of the LED lamp 4 on a wall W2.

[0045] FIG. 3B shows a sketch of the light cones L2; L3 exiting from the second preferred embodiment of the device 1 according to the invention onto a projection surface P in a later, second snapshot. Here, the LED lamp 5 dims straight down, whilst the LED lamp 5 dims straight up and creates a new light cone L3. In this case, the light cones L2 and L3 travel on the wall W2 in arrow direction P and the impression of a moving person is created here for the external observer B. On the basis of FIG. 3B, it is indicated thatcompared with FIG. 2Bthe overlap of the light cones L2; L3 is smaller. Also, the arrow P is longer with the light-shaping element 12 according to FIG. 3B than without light-shaping element 12 according to FIG. 2B, which points to a stronger delimitation of the light cones L2; L3. Furthermore, it can be seen particularly well from FIG. 3B that the depressions 13 belonging to the external LED lamps 5; 5 are open or tilted to the external ends, in order to achieve an illumination which is as wide as possible, virtually corresponding to the technically possible beam angle of the LED lamps 5; 5, i.e. towards the wall W2, wherein an angle 3 between the side surface orientated towards the wall W2 and a plane E defined by the LED circuit board 3 preferably corresponds to less than 20, whilst the opposite side surface is, at most, at right angles to the plane E.

[0046] FIG. 4 shows a schematic illustration of a plurality of the preferred embodiments of the device according to the invention connected to a wireless network environment 21.

[0047] On the basis of an external control device, here a smartphone 20 by way of example, it may be possible to activate and configure the device 1 for example via the internet and an internet router 22. Preferably, a suitable app is installed on the smartphone 20 for this.

[0048] Alternatively or additionally, the device 1 may comprise a Bluetooth module, as a result of which it may also be possible to activate and configure the external control device directly using the device.

[0049] Preferably, in addition, one device 1 additionally comprises a user interface, which can be operated manually, in each case.
