Abstract
Description
Feuer künstlich durch Lichteffekte zu erzeugen, ist seit der Erfindung der Glühlampe technisch möglich geworden. Allerdings ist die Lebensdauer der Glühfaden durch den gepulsten Betrieb stark eingeschränkt. Es werden daher z. B. für den Modellbau Glühlämpchen mit einer kurzen Glühwendel verwendet.Generating fire artificially through lighting effects has been technical since the invention of the incandescent lamp become possible. However, the life of the filament is due to the pulsed operation highly limited. There are therefore z. B. for modeling light bulbs with a short Incandescent filament used.
Selbst gasgefüllte Leuchtmittel brauchen eine gewisse Reaktionszeit bis zum vollen Aufleuchten, um ein Flackern nachzuahmen. Schneller, aber dafür in der Helligkeit und Größe eingeschränkt, ist die bereits bekannte Flackerkerze mit E14-Glühlampenfassung. Diese Flächenglimmlampe benutzt zwei Elektroden, die wie ein Hörnerblitzableiter angeordnet sind. Die nach oben laufende Entladung reißt irgendwann ab und startet weiter unten wieder neu. Dadurch wird eine künstliche Steuerung eines Zufalleffektes überflüssig. Künstliche Feuer mit Glühlampen hingegen verfügen über eine elektronische Steuerung, die wie ein Zufallsgenerator arbeitet. Farblich abgestimmte, lichtdurchlässige Hauben vermitteln so den Eindruck von Kohlen- oder Holzfeuer.Even gas-filled bulbs need a certain reaction time to fully light up, to mimic a flickering. Faster, but limited in brightness and size, is the well-known flickering candle with E14 bulb holder. This glow lamp uses two electrodes that are arranged like a horn lightning rod. The up unloading stops at some point and starts again below. This will make one Artificial control of a random effect is superfluous. Artificial fire with incandescent lamps on the other hand have an electronic control that works like a random generator. Color-coordinated, translucent hoods give the impression of coal or Wood fire.
Energiewirtschaftlich, effizientere und sehr schnell ansprechende Lichtquellen einer Farbe wie die Leuchtdiode benötigen für gleiche Zwecke eine Verteilung ihres konzentrierten Lichtaustritts auf eine größere Fläche. Die Veröffentlichungsnummer DE 197 28 354 A1 zeigt dies mit einer auf die Leuchtdiode aufgesetzten Optik. Gleiche Zwecke erfüllt der bekannte Lichtleiter, wenn durch ihn ein Austritt aus der Längsseite möglich ist. Economical, efficient and very quickly responsive light sources of a color like the light-emitting diodes require a distribution of their concentrated light emission for the same purposes to a larger area. The publication number DE 197 28 354 A1 shows this with a the light emitting diode attached optics. The known light guide fulfills the same purposes when through an exit from the long side is possible.
Die Gefahren mit Feuer sind hinreichend bekannt. Offenes Licht ist aus polizeilicher Sicht nicht immer zugelassen oder überhaupt physikalisch möglich, z. B. unter Wasser nur mit erheblichen technischen Aufwand. Da der Mensch nicht auf diesen Licht-Anreiz verzichtet, soll ein künstlicher Ersatz als unproblematische Ergänzung dienen.The dangers of fire are well known. From the police point of view, open light is not always approved or physically possible at all, e.g. B. under water only with considerable technical effort. Since humans do not forego this light incentive, one should serve as an unproblematic supplement.
Eine Anordnung von einer oder mehrerer kohärenter, getakteter Lichtquellen innerhalb eines Lichtleiters erzeugt ein Licht, das offenem Feuer in Form von Kerzen oder Fackeln für das menschliche Auge ähnlich ist. Dieses Licht kann jeder Farbe enthalten.An arrangement of one or more coherent, clocked light sources within one Light guide creates a light that is open fire in the form of candles or torches for that human eye is similar. This light can contain any color.
Praktisch geeignet ist die Leuchtdiode, durch deren Öffnungswinkel ein definierter Lichtkegel
entsteht. Wird diese in einen hohlen, z. B. gerade geführten Lichtleiter positioniert, dessen Wand
abstand sehr groß und dessen Wandstärke groß gegen die Wellenlänge der abgestrahlten
Frequenz ist, dann wird das Licht auf drei verschiedenen Wegen transportiert:
The light emitting diode, whose opening angle creates a defined light cone, is suitable in practice. If this is in a hollow, e.g. For example, if the light guide is just guided, the wall distance is very large and the wall thickness is large compared to the wavelength of the emitted frequency, then the light is transported in three different ways:
- 1. Direkt durch den hohlen Lichtleiter.1. Directly through the hollow light guide.
- 2. Durch Mehrfachreflektion an den Lichtleiterwänden.2. Through multiple reflection on the light guide walls.
- 3. Innerhalb der Lichtleiterwand selber.3. Inside the light guide wall itself.
Je nach Eintrittswinkel auf die Wände des Lichtleiters entstehen aufgrund des Brechungsindexes vom Material Interferenz-Erscheinungen durch Gangunterschiede. Der Lichtaustritt und die damit flächenmäßige große Verteilung erfolgt z. B. durch eine rauhe Oberfläche der Lichtleiter außenseite. Wird nun zusätzlich die Lichtquelle z. B. mit einem Multivibrator in schneller Ab folge ein- und wieder ausgeschaltet, kann das menschliche Auge nicht mehr exakt folgen und daher ein Flimmern wahrnehmen, daß einer im Wind flackernde Flamme täuschend ähnlich sieht.Depending on the angle of entry to the walls of the light guide, this results from the refractive index from the material interference phenomena due to path differences. The light emission and the so there is a large distribution z. B. by a rough surface of the light guide outdoors. Now, in addition, the light source z. B. with a multivibrator in rapid Ab follow on and off again, the human eye can no longer follow exactly and therefore perceive a flicker that is deceptively similar to a flame flickering in the wind sees.
Verstärken kann man diesen Effekt, wenn zwei der Kennlinien gesteuerten Leuchtdioden verschiedene Arbeitspunkte haben und so bei gleich großer Stromeinspeisung unterschiedliche Lichtstärken aufweisen.This effect can be intensified if two of the characteristic curves controlled LEDs have different working points and so different with the same large power supply Have light levels.
Im Vergleich zu anderen Lösungen steht die Wirtschaftlichkeit im Vordergrund. Ein Batterie betrieb ist ebenso wie eine tragbare Lösung als Handfackel möglich. Neben der farblichen Aus wahl der Farbe des Feuers, hängt die augenscheinliche Größe vom Abstrahlwinkel der Licht quelle, dem Abstand des Lichtleiters zur dieser und seiner Länge sowie von der Lichtstärke der Quelle ab. Die Anordnung kann sowohl Kerzenlicht simulieren, eine Wachsfackel wie auch die langgezogene Flamme eines Brenners. Mehrere dieser Anordnungen ergeben den Eindruck eines Flammenmeeres.In comparison to other solutions, the focus is on economy. A battery Operation is possible as well as a portable solution as a hand torch. In addition to the colored Aus Choosing the color of the fire, the apparent size depends on the beam angle of the light source, the distance of the light guide to this and its length, as well as the light intensity of the Source from. The arrangement can simulate candlelight, a wax torch as well elongated flame of a burner. Several of these arrangements give the impression of one Flames Sea.
