Definitions
- the invention relates to a device for optical simulation of a flame or a fire and in particular for simulating a fireplace with optical means.
- Devices are known in which an as realistic as possible visual representation or simulation of a fireplace, e.g. a chimney fire or the like is achieved. Such simulations are e.g. also in combination with other devices, e.g. with electric or gas-fired heaters, whereby it is important to achieve by interaction with generated heat a realistic as possible illusion of a fireplace.
- the DE 10 2004 016 156 A1 shows such an example.
- a rotating profiled roller is backlit to produce in conjunction with one or more light sources as possible flame-like visual impressions and silhouettes on a kind of projection surface.
- the invention is based on the object to provide a device for the optical simulation of a fireplace, which is able to realize in a particularly simple and reliable manner with comparatively low energy and construction costs, a particularly realistic optical flame representation.
- An apparatus for optical simulation of a fireplace comprises a projection device and a projection surface, wherein the projection device is adapted to generate an image of a flame or a part of a flame and to project onto the projection surface for optical imaging, and wherein the projection device for image formation imaging device in the manner of a projection mask, for example a slide, through which the image can be generated by exposure.
- the projection device can have one or more individual projectors, each with an image-generating device for image generation and with a lighting device for illuminating the image-generating device.
- the illumination device may be formed with a single light source, in particular if a plurality of individual projectors are provided.
- each individual projector has a plurality of light sources, wherein at most a part of the image can be generated by partial illumination of each of the light sources by their spatial arrangement in the individual projector and / or by their activation and in cooperation with the image generation device.
- the control of the light sources may relate to the time profile of the light field, the spatial course and / or the intensity distribution.
- a control device can be provided by which the spatial and / or temporal lighting behavior and the image generation behavior of the individual projectors and in particular of the individual light sources of the individual projectors can be controlled.
- This control device can have a memory device, by means of which, in particular externally, control data for the spatial and temporal control of the illumination and / or the imaging, ie for the control of the individual projectors and / or the light sources can be stored.
- the storage device of the control device can be designed as a removable storage medium or have such.
- a single projector can in each case have a condenser optic or a collimating optic between the illumination device and the image generation device as well as a projection optics between the image generation device and the projection surface.
- These optics may e.g. each formed by a single suitable lens or a lens system.
- the illumination device can each have one or more LEDs with a white or color-emitting emission spectrum as the light source. Preference is given to combinations of yellow and white LEDs, because they represent a good compromise of suitable spectral possibilities and financial outlay. In addition, e.g. also red LEDs are provided.
- the projection surface may be a reflective projection surface or a transmitting projection surface in the manner of a ground-glass screen.
- the projection surface may be formed with a curved and / or inclined course such that a light intensity of the projection light falling off the projection surface before projection on the projection surface is at least partially compensated for or compensated for after the reflection or transmission at the projection surface, in particular at a distance from the projection device is.
- the projection surface may have an area which is more curved or inclined than the rest of the area in an upper area. Due to the increased curvature in the upper area, the incident light, although weakened due to the greater distance from the light sources arranged below, is reflected on a smaller area in relation to the lower area, so that a brighter light impression again arises. Overall, this can make the impression of brightness even.
- a noise generating device may be formed with a loudspeaker device, which are designed to generate and deliver a simulated flame or combustion noise.
- the noise generating device may comprise a memory device, by which, particularly externally, control data for generating noise can be stored or adjusted.
- This storage device of the noise generating device can be designed as a removable storage medium or have such.
- a housing of the device is formed with a bottom area, a lid area, a rear side and a front side, wherein the projection device is arranged in the area of the floor area and wherein either (a) the rear side forms, is or has a reflective projection area and the front side is transparent or (b) the front side forms, is or has a transmissive projection surface.
- a deep-drawn relief element in the form of a photo-realistic relief image can be formed as wood or glutimitatine in such a way that the projection device is obscured by an observer when viewed through the front side.
- a reflector can be formed in the cover region of the housing in such a way that scattered light from the projection device arranged at the bottom is reflected back downwards at an acute angle.
- the light may come from an additional, e.g. arranged in the lower region of the housing, are not reflected as a projection device serving lighting device.
- the reflected light then radiates e.g. into an area in front of the device, but outside the device, there to e.g. to illuminate the floor in front of the device. This additionally improves the impression of a real fire.
- It can be formed on a common carrier in the form of a board, a plurality of light sources or all light sources of a single projector or multiple individual projectors or all individual projectors. This makes it possible to achieve a compact design.
- a single projector may preferably have four light sources arranged in a plane, wherein two of the light sources are arranged side by side on a first line X in a first extension direction in order to produce laterally adjacent lower flame regions during the image formation, and wherein the other two light sources are spatially spaced from each other and from the first two light sources and disposed therebetween and along a second line Y along a second spanwise direction perpendicular to the first spanwise direction to overlap second flame areas superimposed on the first flame areas during imaging produce.
- This arrangement of four light sources eg four LEDs, a particularly realistic Flammeindruck can be simulated.
- the projection device can be configured in such a way that the image of the flame or of the flame parts can be projected by the projection device onto the projection surface in such a way that the image edges on the projection surface appear out of focus to the viewer.
- the light sources of the projection device can be controlled individually in order to be able to change at least the brightness of the light sources.
- Algorithms for driving the light sources are stored in the control device of the device, wherein the algorithms have or display different schemas. This means, on the one hand, that several sequences of activation (brightness control) of the relevant light source in the form of algorithms can be stored for each individual light source. In addition, various scenarios in the form of combinations of such sequences of different light sources may be stored as algorithms.
- the algorithms thus act at least in two, preferably in three control planes: First, the algorithms make it possible to change the brightness of each individual light source in a certain way. In the higher level, the light sources of a single projector are controlled by a sequence of different light source controls, so that the individual projector alone can produce the most realistic possible flame image. Finally, several individual projectors are controlled with the aid of algorithms in the level above them, in order to produce different flame images in cooperation with the individual projectors.
- the algorithms can be selected according to a given rule, according to the random principle and / or according to a weighted random principle.
- the algorithm contains a predetermined control of the individual projectors and the light sources.
- the predetermined rule may e.g. but also changed by the operator, e.g. to be able to switch between a roaring fire and a glowing ember.
- Weighted randomness takes into account that small and large flames do not occur with equal probability in a realistic chimney fire. For this purpose, it is determined in which frequency in a real fire areas appear light and dark. This frequency is then replicated by the weighted random number generator.

- the projection surface 31 is curved more strongly in the upper region than in the lower region, in which the projection surface 31 can also extend flat. As a result, a homogenization of the brightness impression of the flame image is achieved, which the viewer B perceives from the outside.
- FIGS. 13A and 13B show how, via a plurality of individual projectors 20-1,..., 20-4, which respectively generate independent flame segments F1,..., F4, an overall image F of a flame can be realized which shows a superposition of the individual flame segments F1, ... represents F4.

- an optionally external control unit e.g. a remote control
- the behavior of the device can be controlled, e.g. in view of the overall brightness, history and speed of the flame sequences, sequence selection and the like. This makes the impression of a calm or influenced fire and a low or high blazing fire selectable. If necessary, the brightness can be adapted to the environment.
- the acoustic impression can also be adapted to the visual impression and the visual appearance. This is also accessible via the remote control.
- the remote control can be used to select different control programs for the flame simulation and for the sound module.
- the simulation unit or device as a whole preferably consists of a plurality of individual projectors or mini-projectors. Furthermore, a control, a sound or noise module, a corresponding memory extension and a corresponding power supply are conceivable.
- Each of the individual projectors can either represent a total of one flame, possibly of several parts, or even only one flame part. In the latter case, that is, when a single projector only represents one flame part, when using a plurality of projectors, an arrangement can be selected such that, in cooperation with the individual projectors, the individual flame parts can be optically superimposed to form an overall flame.
- each of the single projectors preferably two light sources, e.g. to provide two LEDs, but preferably three, four or more light sources are formed, e.g. in the form of LEDs. These are controlled in such a way that a corresponding temporal sequence results, which represents a liquid flame image, e.g. in the form of a flame rising in its motion.
- the imaging device ie in particular the slide
- only a partial illumination for imaging can be achieved, e.g. also in the sense of ascending the flame.
- Such a simulated flame movement can therefore be realized with only one projector.
- a multi-colored flame By using a color slide and a white light source, a multi-colored flame can be displayed. Alternatively, a multi-colored flame may also be obtained by using colored light sources, e.g. colored LEDs are generated. Preferably priced yellow LEDs are used and at least a more expensive white LED. By their interaction, typical flames, e.g. in blue or white color.
- colored light sources e.g. colored LEDs are generated.
- Preferably priced yellow LEDs are used and at least a more expensive white LED.
- Another aspect of a realistic flame simulation can be the targeted defocusing of the projected images or projected partial images. This is done in conjunction with the control of the various light sources, that is, in particular the LEDs and the staggered images generated thereby, wherein the displacement of the images a flame movement or a movement of the flame tongue is suggested. This makes it possible to enable a very realistic flame representation with just one projector.
- the light intensity can be increased in an upper region, that is to say further away from the projection device.
- the spatial limit of the flame in the upper region ie at a further distance from the projection device, can be displayed improved.
- a flame image may e.g. divided into several segments, the various segments can be represented either by the use of multiple light sources and their control in a single projector or by superimposing the projection images of different projectors. Of course, both measures can be combined.
- the optical superimposition of the different segments then leads again to an overall picture, that is to an overall representation of a flame.
- the different segments can either be sharply delimited against each other spatially, but also conceivable is a partial overlap of the segments, in terms of both space and time, so that overall a particularly realistic spatial and temporal evolution, ie a flame movement can be suggested.
- a single projector can therefore also represent individual flame segments, in particular if they have no connection with a main flame shown, so that in this way detached from a main flame flame splashes are visually displayed.
- At least one further light source e.g. be provided in the form of an LED. This can e.g. also located outside of a designated projector but associated with it, e.g. in the area of the flame root. This additional light source can therefore also be used to illuminate the relief image for the simulated combustion bed.

Derartige bekannte Vorrichtungen erfordern einigen Bauraum und aufgrund der Verwendung beweglicher Teile einen hohen konstruktiven Aufwand, was in der Folge zu hohen Herstellungs- und Materialkosten führen kann.Such known devices require some space and due to the use of moving parts a high design effort, which can result in high production and material costs as a result.
Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zur optischen Simulation eines Kaminfeuers zu schaffen, welche in der Lage ist, auf besonders einfache und zuverlässige Art und Weise unter vergleichsweise geringem Energie- und Bauaufwand eine besonders realitätsnahe optische Flammendarstellung zu realisieren.The invention is based on the object to provide a device for the optical simulation of a fireplace, which is able to realize in a particularly simple and reliable manner with comparatively low energy and construction costs, a particularly realistic optical flame representation.
Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.The object is achieved by a device having the features of
Eine Vorrichtung zur optischen Simulation eines Kaminfeuers weist eine Projektionseinrichtung und eine Projektionsfläche auf, wobei die Projektionseinrichtung dazu ausgebildet ist, ein Bild einer Flamme oder eines Teils einer Flamme zu erzeugen und zur optischen Abbildung auf die Projektionsfläche zu projizieren, und wobei die Projektionseinrichtung zur Bilderzeugung eine Bilderzeugungseinrichtung nach Art einer Projektionsmaske, z.B. eines Dias aufweist, durch welche das Bild durch Belichten erzeugbar ist.An apparatus for optical simulation of a fireplace comprises a projection device and a projection surface, wherein the projection device is adapted to generate an image of a flame or a part of a flame and to project onto the projection surface for optical imaging, and wherein the projection device for image formation imaging device in the manner of a projection mask, for example a slide, through which the image can be generated by exposure.
Es ist also eine Idee der Erfindung, bei besonders geringem Aufwand eine besonders realistische Flammendarstellung dadurch zu erzielen, das an Stelle beweglicher Elemente eine Projektionseinrichtung verwendet wird, bei welcher eine Bilderzeugungseinrichtung ein Bild einer Flammendarstellung trägt oder erzeugt. Dies kann mit Hilfe eines Diapositivs oder einer anderen geeignete Projektionsmaske erfolgen. Als Bilderzeuger denkbar sind damit außer Dias auch andere transmittierend oder in Transmission arbeitende Anzeigemittel, z.B. Mikro- oder LCD-Displays. Weiterhin sind auch in Reflexion arbeitende Anzeigemittel als Bilderzeuger einsetzbar, wobei wieder Mikro- oder LCD-Displays genannt seien.It is therefore an idea of the invention to achieve a particularly realistic flame representation with particularly little effort by using a projection device instead of moving elements, in which an image-generating device carries or generates an image of a flame representation. This can be done with the help of a slide or another suitable projection mask. As image generators, other than slides, it is also possible to use other transmissive or transmissive display means, e.g. Micro or LCD displays. Furthermore, also working in reflection display means can be used as an image generator, again micro or LCD displays are called.
Die Projektionseinrichtung kann ein oder mehrere Einzelprojektoren aufweisen, mit jeweils einer Bilderzeugungseinrichtung zur Bilderzeugung und mit einer Beleuchtungseinrichtung zur Beleuchtung der Bilderzeugungseinrichtung.The projection device can have one or more individual projectors, each with an image-generating device for image generation and with a lighting device for illuminating the image-generating device.
Die Beleuchtungseinrichtung kann mit einer einzigen Lichtquelle ausgebildet sein, insbesondere dann, wenn mehrere Einzelprojektoren vorgesehen sind.The illumination device may be formed with a single light source, in particular if a plurality of individual projectors are provided.
Es ist jedoch möglich, dass jeder Einzelprojektor eine Mehrzahl von Lichtquellen aufweist, wobei durch jede der Lichtquellen durch deren räumliche Anordnung im Einzelprojektor und/oder durch deren Ansteuerung und im Zusammenwirken mit der Bilderzeugungseinrichtung durch partielles Beleuchten höchstens ein Teil des Bilds erzeugbar ist. Dabei kann sich die Ansteuerung der Lichtquellen auf den zeitlichen Verlauf des Lichtfeldes, den räumlichen Verlauf und/oder auf die Intensitätsverteilung beziehen.However, it is possible that each individual projector has a plurality of light sources, wherein at most a part of the image can be generated by partial illumination of each of the light sources by their spatial arrangement in the individual projector and / or by their activation and in cooperation with the image generation device. In this case, the control of the light sources may relate to the time profile of the light field, the spatial course and / or the intensity distribution.
Es kann eine Steuereinrichtung vorgesehen sein, durch welche das räumliche und/oder zeitliche Beleuchtungsverhalten und das Bilderzeugungsverhalten der Einzelprojektoren und insbesondere der einzelnen Lichtquellen der Einzelprojektoren steuerbar sind.A control device can be provided by which the spatial and / or temporal lighting behavior and the image generation behavior of the individual projectors and in particular of the individual light sources of the individual projectors can be controlled.
Diese Steuereinrichtung kann eine Speichereinrichtung aufweisen, durch welche, insbesondere von extern, Steuerdaten zur räumlichen und zeitlichen Steuerung der Beleuchtung und/oder der Abbildung, d.h. zur Ansteuerung der Einzelprojektoren und/oder der Lichtquellen speicherbar sind.This control device can have a memory device, by means of which, in particular externally, control data for the spatial and temporal control of the illumination and / or the imaging, ie for the control of the individual projectors and / or the light sources can be stored.
Die Speichereinrichtung der Steuereinrichtung kann als Wechselspeichermedium ausgebildet sein oder ein solches aufweisen.The storage device of the control device can be designed as a removable storage medium or have such.
Ein Einzelprojektor kann jeweils eine Kondensoroptik oder eine Kollimationsoptik zwischen der Beleuchtungseinrichtung und der Bilderzeugungseinrichtung sowie eine Projektionsoptik zwischen der Bilderzeugungseinrichtung und der Projektionsfläche aufweisen. Diese Optiken können z.B. von jeweils einer einzigen geeigneten Linse oder einem Linsensystem gebildet werden.A single projector can in each case have a condenser optic or a collimating optic between the illumination device and the image generation device as well as a projection optics between the image generation device and the projection surface. These optics may e.g. each formed by a single suitable lens or a lens system.
Die Beleuchtungseinrichtung kann als Lichtquelle jeweils eine oder mehrere LEDs mit einem weißen oder farblich erscheinenden Emissionsspektrum aufweisen. Bevorzugt werden Kombinationen aus gelben und weißen LEDs, weil diese einen guten Kompromiss aus geeigneten spektralen Möglichkeiten und finanziellem Aufwand darstellen. Zusätzlich können z.B. auch rote LEDs vorgesehen werden.The illumination device can each have one or more LEDs with a white or color-emitting emission spectrum as the light source. Preference is given to combinations of yellow and white LEDs, because they represent a good compromise of suitable spectral possibilities and financial outlay. In addition, e.g. also red LEDs are provided.
Die Projektionsfläche kann eine reflektierende Projektionsfläche oder eine transmittierende Projektionsfläche nach Art einer Mattscheibe sein.The projection surface may be a reflective projection surface or a transmitting projection surface in the manner of a ground-glass screen.
Die Projektionsfläche kann mit einem derart gewölbten und/oder geneigten Verlauf ausgebildet sein, dass dadurch eine vor der Projektion an der Projektionsfläche ungleichmäßige, insbesondere mit Abstand von der Projektionseinrichtung hin abfallende Lichtstärke des Projektionslicht nach der Reflexion oder Transmission an der Projektionsfläche zumindest teilweise kompensiert oder kompensierbar ist.The projection surface may be formed with a curved and / or inclined course such that a light intensity of the projection light falling off the projection surface before projection on the projection surface is at least partially compensated for or compensated for after the reflection or transmission at the projection surface, in particular at a distance from the projection device is.
Insbesondere kann die Projektionsfläche in einem oberen Bereich einen gegenüber dem restlichen Bereich stärker gekrümmten oder geneigten Bereich aufweisen. Durch die stärkere Krümmung im oberen Bereich wird das auftreffende Licht, obwohl aufgrund der größeren Entfernung von den unten angeordneten Lichtquellen geschwächt, auf einer im Verhältnis zum unteren Bereich kleineren Fläche reflektiert, so dass wieder ein hellerer Lichteindruck entsteht. Insgesamt kann dadurch der Helligkeitseindruck vergleichmäßigt werden.In particular, the projection surface may have an area which is more curved or inclined than the rest of the area in an upper area. Due to the increased curvature in the upper area, the incident light, although weakened due to the greater distance from the light sources arranged below, is reflected on a smaller area in relation to the lower area, so that a brighter light impression again arises. Overall, this can make the impression of brightness even.
Zur Unterstützung einer wirklichkeitsgetreuen Simulation eines Kaminfeuers kann eine Geräuscherzeugungseinrichtung mit einer Lautsprechereinrichtung ausgebildet sein, welche zur Erzeugung und Abgabe eines simulierten Flammen- oder Verbrennungsgeräuschs ausgebildet sind.To support a realistic simulation of a chimney fire, a noise generating device may be formed with a loudspeaker device, which are designed to generate and deliver a simulated flame or combustion noise.
Die Geräuscherzeugungseinrichtung kann eine Speichereinrichtung aufweisen, durch welche, insbesondere von extern, Steuerdaten zur Geräuscherzeugung speicherbar oder anpassbar sind.The noise generating device may comprise a memory device, by which, particularly externally, control data for generating noise can be stored or adjusted.
Diese Speichereinrichtung der Geräuscherzeugungseinrichtung kann als Wechselspeichermedium ausgebildet sein oder ein solches aufweisen.This storage device of the noise generating device can be designed as a removable storage medium or have such.
Vorzugsweise ist ein Gehäuse der Vorrichtung ausgebildet mit einem Bodenbereich, einem Deckelbereich, einer Rückseite sowie einer Vorderseite, wobei im Bereich des Bodenbereichs die Projektionseinrichtung angeordnet ist und wobei entweder (a) die Rückseite eine reflektive Projektionsfläche bildet, ist oder aufweist und die Vorderseite transparent ist oder aber (b) die Vorderseite eine transmittierende Projektionsfläche bildet, ist oder aufweist.Preferably, a housing of the device is formed with a bottom area, a lid area, a rear side and a front side, wherein the projection device is arranged in the area of the floor area and wherein either (a) the rear side forms, is or has a reflective projection area and the front side is transparent or (b) the front side forms, is or has a transmissive projection surface.
Im Bodenbereich des Gehäuses kann, insbesondere zur Abdeckung der Projektionseinrichtung, als Holz- oder Glutimitatsein tief gezogenes Reliefelement in Form eines fotorealistischen Reliefbildes derart ausgebildet sein, dass die Projektionseinrichtung bei Einsichtnahme über die Vorderseite für einen Beobachter verdeckt ist.In the bottom region of the housing, in particular for covering the projection device, a deep-drawn relief element in the form of a photo-realistic relief image can be formed as wood or glutimitatine in such a way that the projection device is obscured by an observer when viewed through the front side.
Ferner kann im Deckelbereich des Gehäuses ein Reflektor derart ausgebildet sein, dass Streulicht von der unten angeordneten Projektionseinrichtung in einem spitzen Winkel wieder nach unten reflektiert wird. Ebenso kann das Licht von einer zusätzlichen, z.B. im unteren Bereich des Gehäuses angeordneten, nicht als Projektionseinrichtung dienenden Beleuchtungseinrichtung reflektiert werden. Das reflektierte Licht strahlt dann z.B. in einen Bereich vor der Vorrichtung, jedoch außerhalb der Vorrichtung, um dort z.B. den vor der Vorrichtung vorhandenen Fußboden zu erhellen. Dadurch wird der Eindruck eines echten Kaminfeuers zusätzlich verbessert.Furthermore, a reflector can be formed in the cover region of the housing in such a way that scattered light from the projection device arranged at the bottom is reflected back downwards at an acute angle. Likewise, the light may come from an additional, e.g. arranged in the lower region of the housing, are not reflected as a projection device serving lighting device. The reflected light then radiates e.g. into an area in front of the device, but outside the device, there to e.g. to illuminate the floor in front of the device. This additionally improves the impression of a real fire.
Es können eine Mehrzahl von Lichtquellen oder sämtliche Lichtquellen eines Einzelprojektors oder mehrere Einzelprojektoren oder sämtliche Einzelprojektoren auf einem gemeinsamen Träger in Form einer Platine ausgebildet sein. Dadurch lässt sich ein kompakter Aufbau erreichen.It can be formed on a common carrier in the form of a board, a plurality of light sources or all light sources of a single projector or multiple individual projectors or all individual projectors. This makes it possible to achieve a compact design.
Ein Einzelprojektor kann vorzugsweise vier Lichtquellen aufweisen, welche in einer Ebene angeordnet sind, wobei zwei der Lichtquellen nebeneinander auf einer ersten Linie X in einer ersten Erstreckungsrichtung angeordnet sind, um bei der Bilderzeugung lateral nebeneinander liegende untere Flammenbereiche zu erzeugen, und wobei die beiden anderen Lichtquellen voneinander und von den ersten beiden Lichtquellen räumlich beabstandet und zwischen diesen sowie auf einer zweiten Line Y entlang einer zweiten Erstreckungsrichtung senkrecht zur ersten Erstreckungsrichtung angeordnet sind, um bei der Bilderzeugung übereinander liegende und über den ersten Flammenbereichen liegende zweite Flammenbereiche zu erzeugen. Durch diese Anordnung von vier Lichtquellen, z.B. vier LEDs, kann ein besonders realistischer Flammeindruck simuliert werden.A single projector may preferably have four light sources arranged in a plane, wherein two of the light sources are arranged side by side on a first line X in a first extension direction in order to produce laterally adjacent lower flame regions during the image formation, and wherein the other two light sources are spatially spaced from each other and from the first two light sources and disposed therebetween and along a second line Y along a second spanwise direction perpendicular to the first spanwise direction to overlap second flame areas superimposed on the first flame areas during imaging produce. This arrangement of four light sources, eg four LEDs, a particularly realistic Flammeindruck can be simulated.
Die Projektionseinrichtung kann derart ausgebildet sein, dass das Bild der Flamme oder der Flammenteile durch die Projektionseinrichtung derart auf die Projektionsfläche projizierbar ist, dass die Bildränder auf der Projektionsfläche für den Betrachter unscharf erscheinen. Das bedeutet, dass die Fokusierung der Einzelprojektoren derart eingestellt werden kann, dass die Einzelprojektoren auf der Projektionsfläche jeweils ein unscharfes Bild erzeugen. Dadurch verwischen die Bildgrenzen, d.h. die Ränder der projizierten Flamme bzw. Flammenteile. Auf diese Weise kann ein realistischerer Flammeneffekt erzielt werden.The projection device can be configured in such a way that the image of the flame or of the flame parts can be projected by the projection device onto the projection surface in such a way that the image edges on the projection surface appear out of focus to the viewer. This means that the focus of the individual projectors can be set in such a way that the individual projectors each produce a blurred image on the projection surface. As a result, the image boundaries, i. the edges of the projected flame or flame parts. In this way, a more realistic flame effect can be achieved.
Bei einem Verfahren zur optischen Simulation eines Kaminfeuers sind die Lichtquellen der Projektionseinrichtung einzeln ansteuerbar, um wenigstens die Helligkeit der Lichtquellen verändern zu können. In der Steuereinrichtung der Vorrichtung sind Algorithmen zum Ansteuern der Lichtquellen hinterlegt, wobei die Algorithmen verschiedene Schemata aufweisen bzw. abbilden. Das bedeutet zum Einen, dass für jede einzelne Lichtquelle mehrere Abfolgen der Ansteuerung (Helligkeitssteuerung) der betreffenden Lichtquelle in Form von Algorithmen hinterlegt werden kann. Zudem können verschiedene Szenarien in Form von Kombinationen von derartigen Abfolgen von verschiedenen Lichtquellen als Algorithmen gespeichert werden.In a method for the optical simulation of a chimney fire, the light sources of the projection device can be controlled individually in order to be able to change at least the brightness of the light sources. Algorithms for driving the light sources are stored in the control device of the device, wherein the algorithms have or display different schemas. This means, on the one hand, that several sequences of activation (brightness control) of the relevant light source in the form of algorithms can be stored for each individual light source. In addition, various scenarios in the form of combinations of such sequences of different light sources may be stored as algorithms.
Die Algorithmen wirken damit wenigstens in zwei, vorzugsweise in drei Steuer-Ebenen: Zum einen ermöglichen es die Algorithmen, die Helligkeit von jeder einzelnen Lichtquelle in einer bestimmten Weise zu verändern. In der darüber liegenden Ebene werden die Lichtquellen eines Einzelprojektors durch eine Abfolge von verschiedenen Lichtquellen-Ansteuerungen gesteuert, so dass der Einzelprojektor bereits allein ein möglichst realistisches Flammenbild erzeugen kann. Schließlich werden in der wiederum darüber liegenden Ebene mehrere Einzelprojektoren mit Hilfe von Algorithmen angesteuert, um im Zusammenwirken der Einzelprojektoren verschiedene Flammenbilder zu erzeugen.The algorithms thus act at least in two, preferably in three control planes: First, the algorithms make it possible to change the brightness of each individual light source in a certain way. In the higher level, the light sources of a single projector are controlled by a sequence of different light source controls, so that the individual projector alone can produce the most realistic possible flame image. Finally, several individual projectors are controlled with the aid of algorithms in the level above them, in order to produce different flame images in cooperation with the individual projectors.
Die Algorithmen können nach einer vorgegebenen Regel, nach dem Zufallsprinzip und/oder nach einem gewichteten Zufallsprinzip gewählt werden. Bei einer vorgegebenen Regel enthält der Algorithmus eine vorgegebene Ansteuerung der Einzelprojektoren und der Lichtquellen. Die vorgegebene Regel kann z.B. aber auch von dem Bediener verändert werden, um z.B. zwischen einem prasselnden Feuer und einer glimmenden Glut umschalten zu können.The algorithms can be selected according to a given rule, according to the random principle and / or according to a weighted random principle. For a given rule, the algorithm contains a predetermined control of the individual projectors and the light sources. The predetermined rule may e.g. but also changed by the operator, e.g. to be able to switch between a roaring fire and a glowing ember.
Im Falle des Zufallsprinzips können vorgegebene Flammenbilder zufällig miteinander kombiniert werden. Ein Zufallsprinzip auf der Ebene der Ansteuerung der einzelnen Lichtquellen hingegen wird im Normalfall nicht sinnvoll sein, weil dadurch kein realistisches Flammenbild erzeugt werden kann.In the case of the random principle, given flame images can be randomly combined with each other. On the other hand, a random principle at the level of the control of the individual light sources will normally not make sense, because this does not produce a realistic flame pattern.
Bei dem gewichteten Zufallsprinzip wird berücksichtigt, dass kleine und große Flammen nicht mit der gleichen Wahrscheinlichkeit in einem realistischen Kaminfeuer auftreten. Hierzu wird ermittelt, in welcher Häufigkeit bei einem realen Feuer Bereiche hell und dunkel erscheinen. Diese Häufigkeit wird dann durch den gewichteten Zufallsgenerator nachgebildet.Weighted randomness takes into account that small and large flames do not occur with equal probability in a realistic chimney fire. For this purpose, it is determined in which frequency in a real fire areas appear light and dark. This frequency is then replicated by the weighted random number generator.

In der Anwendung können zum Beispiel die ersten beiden Lichtquellen 21-1 und 21-2 dazu verwendet werden, einen unteren und somit breiteren Flammenbereich eines Kaminfeuers abzubilden, wogegen die beiden anderen Lichtquelle 21-3 und 21-4 dazu verwendet werden, über dem unteren Flammenbereich angeordnete Einzelflammen oder züngelnde Flammenbereiche im oberen Bereich des Kaminfeuers abzubilden.For example, in use, the first two light sources 21-1 and 21-2 can be used to image a lower and thus wider flame area of a chimney fire, while the other two light sources 21-3 and 21-4 are used above the lower one Flame range arranged single flames or lightening flame areas in the upper area of the fireplace fire map.
Hier dient eine im Bereich der Rückwand 50r des Gehäuses 50 angeordnete, gekrümmte Fläche als in Reflexion arbeitende Projektionsfläche 30, 31. Im unteren Bereich 50a des Gehäuses 50 ist eine Projektionseinrichtung 20 mit einem Einzelprojektor 20-1 erkennbar. Im linken Bereich der
Die Projektionsfläche 31 ist im oberen Bereich stärker gekrümmt als im unteren Bereich, in dem sich die Projektionsfläche 31 auch eben erstrecken kann. Dadurch wird eine Vergleichmäßigung des Helligkeitseindrucks des Flammenbildes erreicht, den der Betrachter B von außen wahrnimmt. Die Bereiche der Projektionsfläche 31, die von dem Einzelprojektor 20-1 weiter entfernt sind und damit naturgemäß dunkler erscheinen müssten werden durch die durch die Krümmung erzwungene Verkleinerung der Projektionsfläche 31 aufgehellt.The projection surface 31 is curved more strongly in the upper region than in the lower region, in which the projection surface 31 can also extend flat. As a result, a homogenization of the brightness impression of the flame image is achieved, which the viewer B perceives from the outside. The areas of the projection screen 31, which are farther away from the single projector 20-1 and therefore would naturally have to appear darker, are lightened by the reduction of the projection surface 31 forced by the curvature.
Die
Dabei sind zwei unterschiedliche Szenarien denkbar:
- Die in der
Figur 13B gezeigten Einzelprojektoren 20-1, ..., 20-4 können auch durch einen einzigen Einzelprojektor gebildet werden, der in verschiedenen Abbildungszyklen betrieben wird, also für sich genommen nacheinander oder gleichzeitig die verschiedenen Flammensegmente F1 bis F4 abzubilden vermag. Je nach Wahl der Abbildungszyklen entsteht dann ein zeitlich wechselnder Eindruck für das Gesamtbild F der Flamme.
- The in the
FIG. 13B shown individual projectors 20-1, ..., 20-4 can also be formed by a single projector, which is operated in different imaging cycles, so taken in succession or simultaneously the different flame segments F1 to F4 is able to map. Depending on the choice of imaging cycles then creates a temporally changing impression of the overall image F of the flame.
Andererseits kann es sich bei den in
Durch ein Überblenden der Segmente in Form von Teilbildern, z.B. in Form einzelner Flammenzungen, wird ein flüssiger Bewegungsablauf für die Flamme erreicht.By blending the segments in the form of sub-images, e.g. in the form of individual tongues of flame, a fluid movement sequence is achieved for the flame.

Durch eine gegebenenfalls externe Bedieneinheit, z.B. einer Fernbedienung, kann das Verhalten der Vorrichtung gesteuert werden, z.B. im Hinblick auf die Gesamthelligkeit, den Verlauf und die Geschwindigkeit der Flammensequenzen, die Sequenzauswahl und dergleichen. Dadurch wird der Eindruck eines ruhigen oder temperamentvollen Feuers und eines niedrigen oder hoch lodernden Feuers auswählbar. Die Helligkeit kann gegebenenfalls der Umgebung angepasst werden.By an optionally external control unit, e.g. a remote control, the behavior of the device can be controlled, e.g. in view of the overall brightness, history and speed of the flame sequences, sequence selection and the like. This makes the impression of a calm or spirited fire and a low or high blazing fire selectable. If necessary, the brightness can be adapted to the environment.
Auch der akustische Eindruck kann jeweils dem optischen Eindruck und der optischen Erscheinung angepasst werden. Dies ist auch mittels der Fernbedienung erreichbar. Über die Fernbedienung können unterschiedliche Ansteuerprogramme für die Flammensimulation und für das Soundmodul ausgewählt werden.The acoustic impression can also be adapted to the visual impression and the visual appearance. This is also accessible via the remote control. The remote control can be used to select different control programs for the flame simulation and for the sound module.
Diese und weitere Aspekte werden nun auf der Grundlage der nachfolgenden Bemerkungen weiter erläutert:
- Gegenstand der Erfindung ist also insbesondere zunächst ein Einzelprojektor, welcher aus mindestens einer Lichtquelle besteht, die der Beleuchtung dient, sowie aus einer Bilderzeugungseinrichtung, vorzugsweise einem Dia oder einer anderen Form von Projektionsmaske. Zur Verbesserung der Lichtausbeute kann vorzugsweise eine Kondensoroptik, z.B. in Form einer Kondensorlinse eingesetzt werden. Zur Verbesserung des Abbildungsverhaltens kann vorzugsweise eine Projektionsoptik, z.B. in Form einer Projektionslinse verwendet werden.
- The invention thus in particular firstly a single projector, which consists of at least one light source, which serves the illumination, as well as an image forming device, preferably a slide or another form of projection mask. To improve the luminous efficacy, a condenser optic, for example in the form of a condenser lens, can preferably be used. To improve the imaging behavior, projection optics, for example in the form of a projection lens, can preferably be used.
Die Simulationseinheit oder -vorrichtung insgesamt besteht vorzugsweise aus einer Mehrzahl von Einzelprojektoren oder Miniprojektoren. Ferner sind eine Ansteuerung, ein Sound- oder Geräuschmodul, eine entsprechende Speichererweiterung sowie eine entsprechende Spannungsversorgung denkbar.The simulation unit or device as a whole preferably consists of a plurality of individual projectors or mini-projectors. Furthermore, a control, a sound or noise module, a corresponding memory extension and a corresponding power supply are conceivable.
Jeder der Einzelprojektoren kann entweder insgesamt eine Flamme, gegebenenfalls aus mehreren Teilen, oder selbst nur ein Flammenteil darstellen. Im letzteren Fall, also dann, wenn ein Einzelprojektor jeweils nur ein Flammenteil darstellt, kann bei der Verwendung einer Mehrzahl von Projektoren eine Anordnung derart gewählt sein, dass im Zusammenwirken der Einzelprojektoren sich die einzelnen Flammenteile zu einer Gesamtflamme optisch überlagern lassen.Each of the individual projectors can either represent a total of one flame, possibly of several parts, or even only one flame part. In the latter case, that is, when a single projector only represents one flame part, when using a plurality of projectors, an arrangement can be selected such that, in cooperation with the individual projectors, the individual flame parts can be optically superimposed to form an overall flame.
Für jeden der Einzelprojektoren sind vorzugsweise zwei Lichtquellen, z.B. zwei LEDs vorzusehen, vorzugsweise werden aber drei, vier oder mehr Lichtquellen ausgebildet, z.B. in Form von LEDs. Diese werden so angesteuert, dass sich eine entsprechende zeitliche Abfolge ergibt, die ein flüssiges Flammenbild darstellt, z.B. in Form einer in ihrer Bewegung aufsteigenden Flamme.For each of the single projectors, preferably two light sources, e.g. to provide two LEDs, but preferably three, four or more light sources are formed, e.g. in the form of LEDs. These are controlled in such a way that a corresponding temporal sequence results, which represents a liquid flame image, e.g. in the form of a flame rising in its motion.
Durch mehrere LEDs oder andere Lichtquellen in einem einzelnen Projektor und eine entsprechende räumliche Anordnung in Bezug auf das Bilderzeugungselement, die Bilderzeugungseinrichtung, also insbesondere das Dia kann nur eine teilweise Ausleuchtung zur Bilderzeugung erreicht werden, z.B. auch im Sinne eines Aufsteigens der Flamme. Eine derartige simulierte Flammenbewegung ist also mit nur einem Projektor realisierbar.By means of several LEDs or other light sources in a single projector and a corresponding spatial arrangement with respect to the imaging element, the imaging device, ie in particular the slide, only a partial illumination for imaging can be achieved, e.g. also in the sense of ascending the flame. Such a simulated flame movement can therefore be realized with only one projector.
Durch Verwendung eines Farbdias und einer weißen Lichtquelle kann eine vielfarbige Flamme dargestellt werden. Alternativ dazu kann eine vielfarbige Flamme auch durch Verwendung farbiger Lichtquellen, z.B. farbiger LEDs erzeugt werden. Vorzugsweise werden preislich günstige gelbe LEDs verwendet und mindestens dazu eine aufwendigere weiße LED. Durch deren Zusammenwirken können typische Flammentöne, z.B. mit blauer oder weißer Farbe, dargestellt werden.By using a color slide and a white light source, a multi-colored flame can be displayed. Alternatively, a multi-colored flame may also be obtained by using colored light sources, e.g. colored LEDs are generated. Preferably priced yellow LEDs are used and at least a more expensive white LED. By their interaction, typical flames, e.g. in blue or white color.
Ein weiterer Aspekt für eine realistische Flammensimulation kann das gezielte Unscharfstellen der projizierten Bilder oder projizierten Teilbilder sein. Dies erfolgt in Verbindung mit der Ansteuerung der verschiedenen Lichtquellen, also insbesondere der LEDs und der dadurch erzeugten versetzten Bilder, wobei durch den Versatz der Bilder eine Flammenbewegung oder eine Bewegung der Flammenzunge suggeriert wird. Dadurch ist es möglich, mit bereits nur einem Projektor eine sehr realistische Flammendarstellung zu ermöglichen.Another aspect of a realistic flame simulation can be the targeted defocusing of the projected images or projected partial images. This is done in conjunction with the control of the various light sources, that is, in particular the LEDs and the staggered images generated thereby, wherein the displacement of the images a flame movement or a movement of the flame tongue is suggested. This makes it possible to enable a very realistic flame representation with just one projector.
Wie bereits erwähnt wurde, kann durch eine gewölbte und/oder geneigte Projektionsfläche die Lichtstärke in einem oberen, also weiter von der Projektionseinrichtung entfernten Bereich gesteigert werden. Zusätzlich ist durch diese Maßnahmen die räumliche Begrenzung der Flamme im oberen Bereich, also in weiterer Entfernung von der Projektionseinrichtung, verbessert darstellbar.As already mentioned, by means of a curved and / or inclined projection surface, the light intensity can be increased in an upper region, that is to say further away from the projection device. In addition, by these measures, the spatial limit of the flame in the upper region, ie at a further distance from the projection device, can be displayed improved.
Ein Flammenbild kann z.B. in mehrere Segmente unterteilt werden, wobei die verschiedenen Segmente entweder durch die Verwendung mehrerer Lichtquellen und deren Ansteuerung in einem einzelnen Projektor oder aber durch Überlagerung der Projektionsbilder verschiedener Projektoren dargestellt werden können. Selbstverständlich sind auch beide Maßnahmen miteinander kombinierbar. Das optische Überlagern der verschiedenen Segmente führt dann wieder zu einem Gesamtbild, also zu einer Gesamtdarstellung einer Flamme. Die verschiedenen Segmente können entweder scharf gegeneinander räumlich abgegrenzt sein, denkbar ist jedoch auch eine teilweise Überlappung der Segmente, und zwar in räumlicher sowie in zeitlicher Hinsicht, so dass insgesamt gesehen eine besonders realistische räumliche und zeitliche Entwicklung, also eine Flammenbewegung suggeriert werden kann.A flame image may e.g. divided into several segments, the various segments can be represented either by the use of multiple light sources and their control in a single projector or by superimposing the projection images of different projectors. Of course, both measures can be combined. The optical superimposition of the different segments then leads again to an overall picture, that is to an overall representation of a flame. The different segments can either be sharply delimited against each other spatially, but also conceivable is a partial overlap of the segments, in terms of both space and time, so that overall a particularly realistic spatial and temporal evolution, ie a flame movement can be suggested.
Ein einzelner Projektor kann also ebenfalls einzelne Flammensegmente darstellen, insbesondere dann, wenn diese keine Verbindung mit einer dargestellten Hauptflamme besitzen, so dass auf diese Art und Weise von einer Hauptflamme losgelöste Flammenspritzer optisch darstellbar sind.A single projector can therefore also represent individual flame segments, in particular if they have no connection with a main flame shown, so that in this way detached from a main flame flame splashes are visually displayed.
Durch ein Überblenden der Segmente in Form von Teilbildern, z.B. in Form einzelner Flammenzungen, wird ein flüssiger Bewegungsablauf für die Flamme erreichbar.By blending the segments in the form of sub-images, e.g. in the form of individual tongues of flame, a fluid movement sequence for the flame is reached.
Zur Erzeugung einer Hintergrundbeleuchtung kann mindestens eine weitere Lichtquelle, z.B. in Form einer LED vorgesehen sein. Diese kann z.B. auch außerhalb eines vorgesehenen Projektors angeordnet aber diesem zugeordnet sein, z.B. im Bereich der Flammenwurzel. Diese zusätzliche Lichtquelle kann also auch dazu verwendet werden, um das Reliefbild für das simulierte Verbrennungsbett zu beleuchten.To generate a backlight, at least one further light source, e.g. be provided in the form of an LED. This can e.g. also located outside of a designated projector but associated with it, e.g. in the area of the flame root. This additional light source can therefore also be used to illuminate the relief image for the simulated combustion bed.
