    FIELD OF THE INVENTION
    The present invention relates to an image projection device for improving the ambience of a room, e.g. B. in the form of a virtual fire. In particular, the present invention relates to an image projection apparatus for projecting multiple images of a fire in different directions simultaneously.
    STATE OF THE ART
    Devices that simulate a three-dimensional effect using mirrors are known. For example, partially translucent mirrors are used to project images from an image source, such as a display or projector, to a viewer so that the images appear to be in thin air or on a static or moving background, the Background can be an object, a collection of objects, or any other background setting.
    CN101124507A discloses a display device for producing quasi-3D images comprising a pyramid-like part and a display means, the display means providing images to be reflected on the pyramid-like part.
    Devices with the aim of simulating the appearance of a fireplace are known in the prior art. While early devices used moving parts and incandescent lamps to simulate flickering flames, current devices have begun to implement flat panel displays for displaying a more convincing picture of a fire. By using mirrors it is possible to achieve a simple depth effect.
    CN205606456U discloses the use of an image display device, emulated or imitation fuel bed elements and a mirror so that the image from the image display device is reflected from the mirror to a viewer while the fuel bed elements are also visible through the mirror.
    US2014373406A discloses an artificial hearth having fuel bed elements arranged in two areas, a display and a dichroic mirror which merges the images of the fuel bed elements and the display.
    The artifical fireplaces known in the prior art do not, however, provide a truly realistic experience, since the flames often do not seem to emanate from the fuel bed elements themselves. Furthermore, the prior art does not provide a truly convincing three-dimensional virtual fireplace, in particular for viewers who do not look directly at the fireplace from the front.
    SUMMARY OF THE INVENTION
    An object of this invention is to provide an image projection apparatus for improving the ambient experience of a room, in particular by providing a fire on multiple channels.
    According to one aspect of the present invention, an image projection apparatus for enhancing the ambient experience of a room is provided. The image projection device is suitable for projecting images of the same or different objects or the same or different information in one or more directions, so that the same or more viewers have a convincing experience, for example a fire in a fireplace.
    In a variant, the image projection device comprises a single partially transparent mirror which is arranged at an angle in such a way that the image is reflected outwards from the display to the viewer.
    In a variant, the image projection device comprises two mutually arranged partially transparent mirrors at an angle, the edges of which are parallel, so that the images are reflected outward from the display in opposite directions. The partially transparent mirrors are rectangular and are preferably arranged at an angle of 40-50 °, particularly preferably 45 ° to the horizontal, so that the upper edges of the partially transparent mirrors are closer together than the lower edges. The upper edges of the partially transparent mirrors are parallel to each other. The upper edges can abut one another or they can also be arranged at a distance from one another. The upper edges of the partially transparent mirror are essentially horizontal and form a surface.
    In a preferred variant, the image projection device comprises partially transparent mirrors which are arranged to form at least three sides of an upright polygonal pyramid. Depending on the field of application, an inverse arrangement can be provided in a suitable case. The top of the pyramid is usually positioned above the base of the polygonal pyramid, with the base being positioned substantially horizontally. The pyramid is preferably designed to give the same or several viewers from several directions a realistic and convincing impression of a picture, an object and / or a scene, such as a wood fire or the like. In a preferred variant, the image projection device comprises a horizontal display which usually shows several different images which are normally coordinated with one another in order to obtain the best results. In an upright position of the pyramid, the display is preferably arranged above the partially transparent mirrors and faces downwards. Each of the multiple images is displayed on a display segment of the same display. The display segment corresponds to one of the partially transparent mirrors, so that the multiple images are each reflected on the partially transparent mirror and projected outward in different directions. Each of the multiple images on the display is typically arranged in a separate display segment. The display segments are regions on the display that typically each display a different image. Depending on the field of application or the operating mode, the display segments can each display a coordinated image of a single virtual object, such as a flame viewed from different angles, or they can display images of different objects or from different and entirely different sources, e.g. B. at least one segment shows a fire or a fireplace, whereas at least one display segment shows information from another source, e.g. In the form of a movie, television or the like. This provides the opportunity for one viewer to see a fireplace while another viewer can watch a movie. Typically, each display segment of the display has a corresponding partially transparent mirror, the partially transparent mirror being positioned below the image segment. The image on each display segment of the display is reflected by the partially transparent mirror corresponding to the display segment and is projected horizontally outward by the image projection device. Therefore, several viewers arranged around the image projection device see a projected image of the image on the display segment, the corresponding partially transparent mirror of which is oriented towards them. The display segments can display images of a common virtual object viewed from different angles so that each viewer viewing the image projection apparatus has a similar viewing experience. The display segments can also display dissimilar images of either different virtual objects or images from entirely different sources so that different viewers have a completely different viewing experience.
    In a variant, the partially transparent mirrors are trapezoidal with a lower edge that is longer than an upper edge.
    In a variant, the partially transparent mirror can also be triangular, each with a lower edge and two side edges that meet at a point.
    In a preferred arrangement, three partially transparent mirrors are arranged such that a central partially transparent mirror is arranged between two side partially transparent mirrors and that the central partially transparent mirror is connected to each of the side partially transparent mirrors at an angle along an edge. The interior angle between the central partially transparent mirror and each of the side partially transparent mirrors is between 80-150 °, preferably between 85 ° -125 °, preferably 90 °. The length of the lower edge of each of the partially transparent mirrors can be the same or different. The length of the lower edge of the central partially transparent mirror can be longer than the length of the lower edge of the side partially transparent mirror. The length of the lower edge of the central partially transparent mirror can equally be shorter than the length of the lower edge of the side partially transparent mirror.
    In a variant, five partially transparent mirrors are arranged such that a central partially transparent mirror is arranged between two intermediate partially transparent mirrors that the central partially transparent mirror is connected to each of the intermediate partially transparent mirrors at an angle along an edge. Two lateral partially transparent mirrors are each arranged next to the intermediate partially transparent mirrors in such a way that they are each connected to one of the intermediate partially transparent mirrors at an angle along an edge. The interior angle between each of the partially transparent mirrors is between 100-150 °, preferably between 110-140 °, preferably 135 °. The angles between the central partially transparent mirror and the intermediate partially transparent mirrors can be different from the angles between the intermediate partially transparent mirrors and the side partially transparent mirrors. The length of each lower edge of the five partially transparent mirrors can be the same or different. The length of the lower edge of the central partially transparent mirror can be longer than the length of the lower edge of the intermediate partially transparent mirror and / or the side partially transparent mirror. Equally, the length of the lower edge of the intermediate partially transparent mirror and / or the side partially transparent mirror can be longer than the length of the central partially transparent mirror.
    In a preferred arrangement, the image projection device further comprises a housing. The housing comprises a base part, a support part and a top part. The base part, the supporting part and the upper part are connected to one another in such a way that the base part is connected to the supporting part and the supporting part is connected to the upper part. The display is arranged in the upper part. The partially transparent mirrors are arranged between the base part and the upper part. The lower edge of the partially transparent mirror rests on or is supported by the base part. The lower edges of the partially transparent mirror form a horizontal surface which is parallel to the upper surface of the base part. Two of the partially transparent mirrors are connected to the support part. The arrangement of the partially transparent mirror forms a space that is delimited by the partially transparent mirror, the base part and the lower part. The side edges of the partially transparent mirror extend from the base part upwards to the top part. In an embodiment in which the partially transparent mirrors are triangular, the side edges of the partially transparent mirrors can meet at a point. Alternatively, in an embodiment in which the partially transparent mirrors are trapezoidal, the side edges of the partially transparent mirrors do not meet at one point and the top edges of the partially transparent mirrors form a horizontal surface which meets the top or leaves a gap. A roof element is arranged on or above the upper edges of the partially transparent mirror. The image projection apparatus is designed to be assembled easily and efficiently. The housing is therefore designed to be assembled first by connecting the base part to the support part. The partially transparent mirrors are then placed and assembled. The display can be arranged in a recessed manner in the upper part in such a way that the display is normally not visible to the viewer. This increases the realism value of the image projection device, since the viewer cannot immediately determine that part of the visible image on the partially transparent mirrors is actually a reflection of the display from the mirrors.
    In a variant, two of the partially transparent mirrors are connected to the support part. The arrangement of the partially transparent mirror forms a space that is delimited by the partially transparent mirror, the base part and the lower part.
    In a variant, four partially transparent mirrors are arranged in a square layout to form a square pyramid if the partially transparent mirrors are triangular, or a square truncated pyramid if the partially transparent mirrors are trapezoidal. The supporting part can extend as a column between the base part and the upper part essentially in the interior of the space formed by the four partially transparent mirrors, so that the supporting part is not immediately visible to the observer and only appears to be held by the partially transparent mirror itself. The support part can also consist of two or more columns which are arranged around the partially transparent mirror in such a way that they extend from the base part to the upper part and support the upper part. In a variant, the upper part of the housing of the image projection device comprises support elements which are designed to support the display so that the display can be lowered onto the support elements during assembly. In order to facilitate the assembly of the image projection device and to make the assembly more efficient, the display is mounted in the device by lowering the display, pointing downwards, into the top of the housing from above. Support members are provided in the top that are adapted to hold or engage the display so that it is held in a downward facing manner. The support elements can be designed as projections, bending sections made of sheet metal, fasteners, etc. The support elements can be arranged in such a way that the screen of the display is recessed opposite the underside of the upper part, so that the display is not immediately visible to the viewer. This increases the realism of the visual effect produced because the viewers cannot easily see that part of the image projected outward from the image projection device is actually a reflection of images from the display.
    In a variant, the partially transparent mirrors are metallic, semitransparent mirrors or dichroic mirrors. Metallic semitransparent mirrors are preferably used which are designed to have a reflectivity and / or a transmissivity that is independent of the wavelength, so that all light wavelengths are reflected and / or transmitted in the same way by the semitransparent mirror. This increases the realism value of the projected image, since the reflected and / or transmitted images have no color cast.
    In a variant is / are one or more of the partially transparent mirror (a) tunable (r) partially transparent (r) mirror, which is / are designed to have a locally or globally adjustable permeability and / or reflectivity, e.g. . B. a particle suspension device, an electrochromic device, a liquid crystal device with dispersed polymer or an OLED device. The transmittance and / or the reflectivity of the tunable partially transparent mirror is designed to be controlled with a signal or an applied voltage. The transmittance and / or reflectivity of the tunable partially transparent mirrors can be controlled individually, so that the transmittance and / or the reflectivity of each mirror can be adjusted independently of other tunable partially transparent mirrors, or all tunable partially transparent mirrors can be controlled simultaneously so that their permeability and / or reflectivity can be changed at the same time. The tunable partially transmissive mirror (s) which has or have a locally adjustable transmissivity and / or reflectivity means that only part of the tunable partially transmissive mirror (s) can be adjusted wherein the part comprises contiguous regions such as a central region, or more generally a subset of the discrete tunable areas. The tunable partially transmissive mirror (s) which has or have a globally adjustable transmissivity and / or reflectivity means that the whole of the tunable partially transmissive mirror (s) is (are) adjusted at once can be. As the transmittance is increased, more light from behind the tunable partially transmitting mirrors passes through the tunable partially transmitting mirrors so that a viewer can more easily see objects behind the partially transmitting mirrors. As the transmittance is lowered, less light from behind the tunable partially transparent mirrors passes through the tunable partially transparent mirrors, so that a viewer can see objects behind the partially transparent mirrors less easily. As the reflectivity of the tunable partially transparent mirror is increased, more light from the images on the display will be reflected on the tunable partially transparent mirror and the viewer can more easily see the projected images. If the reflectivity of the tunable partially transparent mirror is lowered, then less light from the images on the display will be reflected on the tunable partially transparent mirror and the viewer will be less able to see the projected images.
    In a further variant, the support part comprises a vertically oriented second outwardly facing display which is designed to display images. The second display is arranged such that it is at least partially behind the partially transparent mirrors. The second display enables the image projection device in an alternative functional mode to display images not only by reflection on the partially transparent mirrors but also directly, the images then at least partially passing through the partially transparent mirrors.
    In a variant, the one or more of the displays are an LCD display, a TFT display, a plasma display flat screen and / or an OLED screen. In a preferred arrangement, the one or more displays are OLED displays because they have deeper black levels and a greater range of contrast, which creates a more realistic flame effect, especially when the image projection device is used in a room with a low light level, such as a room at night .
    In a variant, the partially transparent mirror comprise a frontal partially transparent mirror which forms an angle of 135 ° -80 °, preferably 110 ° -85 °, particularly preferably 90 ° with each of the two lateral transparent mirrors. The exact angle will depend on the specific implementation of the invention and the overall size and shape of the image projection apparatus desired. An image projection device that is relatively wide compared to its depth, for example to fit into a shallow wall recess, can have partially transparent mirrors at a larger (inner) angle to one another, whereas an image projection device that is essentially as wide as it is deep, partially transparent mirrors at smaller (internal) angles to one another, such as at 90 ° to one another.
    In a variant, the partially transparent mirror comprise at least one rear partially transparent mirror which is arranged on the side of the polygonal pyramid opposite the front partially transparent mirror and is connected to the lateral transparent mirrors.
    In a preferred arrangement, the lower part, the support part and the upper part are constructed from bent sheet metal and the lower part and / or the upper part are Prismoide. The use of bent sheet metal makes construction and assembly simple, efficient and inexpensive. The lower part, the supporting part and the upper part are connected to one another. The lower part, the supporting part and the upper part can either be connected by a seam formed by bending the metal sheet or by using rivets or other connecting means. A prismoid is a three-dimensional body whose tips lie in two parallel planes and whose surfaces are trapezoids or triangles. Alternatively, the lower part and / or the upper part are square truncated pyramids. Alternatively, the lower part and / or the upper part are rectangular cuboids with parallel surfaces, the parallel surfaces being arranged perpendicular to adjacent surfaces. The lower part, the supporting part and the upper part preferably have a cuboid shape with parallel surfaces which meet at 90 °.
    In a preferred arrangement, the housing comprises attachment means on the base part, the support part and / or the upper part for attaching additional cladding elements thereon and / or for enabling the image projection device to be mounted flush with the wall. These attachment means may include guide, locking and / or retention means such as one or more of the following: pins, guide rails, tab sections of sheet metal, holes, threaded fasteners, housing depressions, snap-in fasteners, stops, tabs and wedges.
    In a variant, the base part further comprises adjustable feet for leveling the image projection device. The adjustable feet include nuts that engage the threads of a bolt attached to the base. Rotating the adjustable feet raises and lowers the adjustable feet with respect to the housing. By raising and / or lowering one or more adjustable feet, the device can be leveled so that it is horizontal.
    In a preferred arrangement, the image projection device further comprises ornament elements which are arranged on the base part between the partially transparent mirrors and the support part. The ornamental elements are arranged behind the partially transparent mirrors. The ornamental elements can be fixed to the base or they can be removable. In one variant, the ornament elements can also or exclusively be arranged on the support part.
    In a preferred arrangement, the ornamental elements are fuel bed elements such as one or more of the following: firewood elements, log elements, pine cone elements, coal elements, and stone elements.
    In a preferred variant, the image projection device further comprises a control module, wherein the control module comprises a processor, a memory module and a communication module, and wherein the control module is connected to the one or more displays. The control module is designed to control the one or more displays, for example by switching the display (s) on / off as well as additional settings, such as brightness and contrast settings, and including controlling the media source or the image that the image projection device is to display, for example a picture of a burning fireplace or a movie.
    In a preferred arrangement, the communication module connects in a wired or wireless manner to a network and / or a separate device, such as a personal computing device, a server and / or a television network. The communication module can connect to a LAN network and / or the Internet, for example, via an Ethernet cable. The communication module can wirelessly connect to a WLAN network and / or connect to the separate device via other wireless protocols such as Bluetooth, low-energy Bluetooth or consumer electronics IR, the personal computing device being implemented as a mobile phone or laptop or a remote control can and wherein the server can be implemented as a local server, a switch and / or a router or a remote server. The separate device can exchange data with the image projection device via the communication module in order to control the image projection device and all connected modules. This communication module makes it very convenient for the viewer to control the image projection device because the viewer can control the image projection device at a distance using the remote control or the personal computing device, for example. The viewer can use these devices to change all possible settings of the image projection device and its included modules, for example to set scheduled tasks on the image projection device so that it switches on automatically at certain times of the day and automatically displays a predetermined image. For example, the viewer could use his mobile phone to set the image projection device to display a burning fire in the evening after 8 p.m. This increases the ease of use and the convenience of the image projection apparatus.
    In a variant of the image projection device, the control module further comprises a touch screen. The touch screen is preferably arranged on the front surface of the upper part or on the front surface of the lower part. The touch screen allows the viewer to control the image projection device, including display settings, audio settings, lighting settings of the lights, etc. This makes it very convenient for the viewer to adjust any settings of the image projection device, and the touch display enables a familiar and simple interface with which one wide variety of settings can be controlled via the use of multiple windows, areas and interface elements.
    In a variant, the base part, the support part and / or the upper part further comprise one or more lights, such as LEDs and / or incandescent lamps, which are designed to illuminate the space between the partially transparent mirrors and the support part. These lights can be placed near the top of the partially transparent mirror and can be designed to shine downwards. Further lights can be arranged in the base part and designed to shine upwards through an opening or slots into the space between the partially transparent mirrors and the support part. Further lights can be arranged on the supporting part and arranged to shine outward into the space between the partially transparent mirrors and the supporting part. The luminaires can be broad-spectrum luminaires that emit light over a wide range of frequencies, characterized by an equivalent blackbody temperature, such as red at 1000 K, reddish-orange at 1500 K, yellow at 2800 K, warm white at 4500 K, white at 5500 K. etc. Alternatively, these lights can be narrow spectrum lights that emit light at or near a particular wavelength, such as 630 nm. The lights can help mimic the light produced by various sources such as candlelight, flames, glowing ashes, a sunrise / sunset, a sunny day, blue sky, etc. The brightness and / or color of the lights can be vary over time, for example to achieve a more realistic flame effect, the lights may flicker and fluctuate. The lights can comprise several individual lights, each of which produces light with a different color or intensity and is directed at a different part of the ornamental elements. For example, lights arranged below the ornamental elements and glowing upwards can have a bright yellow color in order to imitate glowing ash, whereas lights arranged above the ornamental elements and glowing downward have a warmer red color in order to imitate flames. Together with the displayed images reflected on the display segments and reflected from the partially transparent mirrors, the ornamental elements illuminated by the lights produce a more realistic image of a burning fire, such as a wood fire, gas fire or coal fire. This leads to an improved ambience effect and experience for the viewer.
    In a variant, the image projection device further comprises a connection to an existing heating device, such as a heating device. The connection can be in the form of a wired connection, such as a data or signal cable, wherein the image projection device can send and / or receive data and / or signals to and / or from the heating device or the existing heating device. Alternatively, the connection can be wireless and can take place over a wireless network such as WLAN, etc. Alternatively, the invention is designed to allow the transfer of a heat transfer fluid, such as hot air or hot water, from the heating device or the existing heating device into the image projection device. In such an embodiment, the image projection device can comprise an additional radiator module for dissipating and / or radiating the heat from the thermal fluid and can have means for moving the heat out of the image projection device either passively, via holes and spaces in the base part, in the support part and / or in the top part, or actively, in which case, in addition to the holes and spaces, means for moving air, such as a fan, could be arranged in the base part or support part as required. The connection to the heater or the existing heating device can be arranged in the support part or the base part of the housing and can comprise pipes, hoses and / or connecting elements.
    In a variant, the image projection device further comprises a heater module, for. B. comprising a gas heater, an electric heater and / or a fan. The heater module is preferably arranged in the base part or the support part of the housing. The heater module can also be arranged on the base part, behind the partially transparent mirrors. In the case in which the heater module is arranged in the base part, the base part may have openings, such as slits or grids, to allow air to flow into, out of and / or through the base part in order to dissipate the heat from the heater module. The heater module can be designed as an infrared heating plate and arranged as a part of the support part, so that a large and diffuse heating source is provided. In another embodiment, the heating module is arranged as a gas heater in the base part, the gas flames extending over the base part into the space between the partially transparent mirrors and the support part. Additional means for discharging the smoke gases, such as a chimney, a pipe or a duct, can be arranged in the image projection device in this embodiment.
    In a preferred variant, the image projection device further comprises an audio module which comprises a loudspeaker which is designed to reproduce audio, such as an audio track, which corresponds to the plurality of images displayed on one or more of the displays. The audio module is preferably integrated into the display. Alternatively, the audio module can be arranged in the upper part, the support part or the base part. The audio module itself includes one or more audio transducers, such as a moving coil speaker, a digital or analog intersection for applying digital signal processing to an input audio signal, such as a band pass filter, and one or more audio amplifiers. Adding the listening experience provided by playing an audio track through the audio module creates a more convincing and realistic experience of, for example, a virtual fireplace and enables the image projection device to also play audio-visual content, which typically includes an audio track together with a video track, such as television, film snippets and movies. The one or more transducers of the audio module are preferably hidden from the viewer, so that the illusion effect of a fireplace, for example, is more convincing.
    In a preferred arrangement, the control module is connected to any additional modules which are either integrated into the image projection device or connected to it. Such additional modules can include the lights, the heating module and the audio module. The control module is designed to manage the image projection device. The control module reads the status of connected modules and can set the status of connected modules. For example, it can control the image displayed on the display, including the image source, which image is displayed on which display segment, and adjust properties related to the image itself, such as brightness, color saturation, etc.
    In a variant, the control module applies corrections to the image by means of digital image processing in order to compensate for the optical distortion due to the partially transparent mirror. The compensation can compensate for the geometry of the partially reflective mirrors, such as their shape and angle between the partially reflective mirrors and the display, and the angles between the partially reflective mirrors and the viewer. The compensation can also compensate for the specific reflectivity and / or transmission values of the partially transparent mirrors, in particular their wavelength-dependent reflectivity, so that, for example, the brightness of certain wavelengths on the display can be increased in order to compensate for a lower reflectivity of the partially transparent mirrors at those same wavelengths.
    In a variant, the multiple images displayed on the display segments of the displays correspond to one or more of the following: static images or moving images, such as images, photographs, videos, television images, film images and moving images of a fire. A display segment can display images of a different type or source as another display segment. For example, a central display segment, which corresponds to a central partially transparent mirror, could display an image of a sports game. At the same time, display segments adjacent to the central display segment, which correspond to partially transparent mirrors adjacent to the central partially transparent mirror, could display an image of a fire. As a result, different viewers arranged around the image projection device can view different content at the same time. For example, a viewer or several viewers, sitting directly in front of the central partially transparent mirror of the image projection device, can enjoy the ambient experience of a fire, whereas viewers who sit on the side of the image projection device so that they are facing another of the partially transparent mirrors , Watch sports or television.
