Description
Beschreibung Elektronische, kabelfreie Kerze Description Electronic, cordless candle
Bisher auf dem Markt befindliche, elektrische Weihnachtskerzen werden über Kabel mit Strom gespeist. Die Ein- und Ausschaltung erfolgt meist über einen elektromechanischen Schalter oder über einfaches Ein- Ausstecken eines Betriebsspannungs- Steckers. Die Abstände der einzelnen kerzen voneinander sind durch die Kabellänge vorgegeben.Electric Christmas candles currently on the market are powered by cables. They are usually switched on and off using an electromechanical switch or by simply plugging and unplugging an operating voltage plug. The distance between the individual candles is determined by the length of the cable.
Erfindungen, die über Funk betrieben werden, sind extrem störanfällig. Inventions that operate via radio are extremely susceptible to interference.
Elektronische, kabelfreie Kerze: Mit internen Batterien betriebene Lampe in Kerzenform.Electronic, cordless candle: Candle-shaped lamp powered by internal batteries.
Bei der in Schutzanspruch 1 angegebenen Erfindung handelt es sich um eine Beleuchtung, ein- und ausschaltbar nur über Empfang eines codierten Funksignals, Trägerfrequenz 433,3 MHz.The invention specified in claim 1 is a lighting device that can be switched on and off only by receiving a coded radio signal, carrier frequency 433.3 MHz.
Aufbau/FunktionsübersichtStructure/Functional overview
(Nummern in Klammern beziehen sich auf Fig.2) Das Empfangsteil besteht aus einer abgewandelten selbstschwingenden Hochfrequenz-Mischstufe (1). Sie erzeugt an ihrem Ausgang ein dauerndes Rechtecksignal von circa 800 kHz.(Numbers in brackets refer to Fig.2) The receiving section consists of a modified self-oscillating high-frequency mixer stage (1). It generates a continuous square-wave signal of approximately 800 kHz at its output.
Zur Weiterverarbeitung wird nicht, wie in Rundfunk-Empfänger-Schaltungen, das "heruntergemischte" Empfangssignal verwendet, sondern direkt das oben beschriebene 800 kHz-Signal:For further processing, the "down-mixed" reception signal is not used, as in radio receiver circuits, but directly the 800 kHz signal described above:
Das codierte HF-Signal vom Sender wird über einen Schwingkreis empfangen. Die Reichweite ist vom Sender abhängig (hier: 10 m W, circa 5 m Reichweite). Eine gesonderte Empfangsantenne ist nicht nötig.The coded RF signal from the transmitter is received via an oscillating circuit. The range depends on the transmitter (here: 10 m W, approx. 5 m range). A separate receiving antenna is not necessary.
Ausgenutzt wird der Effekt, daß die Modulation der ankommenden Trägerfrequenz ebenfalls eine FM-Modulation der Grundfrequenz der Mischstufe (des 800 kHz-Signals) hervorruft.The effect that the modulation of the incoming carrier frequency also causes an FM modulation of the fundamental frequency of the mixer stage (the 800 kHz signal) is exploited.
Die FM-modulierte Grundfrequenz wird ausgekoppelt und erreicht den Eingang des selbsregelnden ZF- Verstärkers (2) (hier wäre "Grundfrequenzverstärker" angebrachter). Das verstärkte Signal wird hier auch demoduliert und dem Decoder zugeführt.The FM-modulated fundamental frequency is extracted and reaches the input of the self-regulating IF amplifier (2) (here "fundamental frequency amplifier" would be more appropriate). The amplified signal is also demodulated here and fed to the decoder.
Der Decoder (3) erzeugt am Ausgang nur dann einen Schaltimpuls, wenn er am Eingang die spezielle Impulsfolge (genau gesagt: Impulsfolge mit richtiger zeitlicher Länge der Impulse) erhält.The decoder (3) only generates a switching pulse at the output if it receives the special pulse sequence (more precisely: pulse sequence with the correct temporal length of the pulses) at the input.
Mangelhafte Selektion des Empfangsteils oder Störungen selbst auf der Empfangsfrequenz werden ignoriert. Das gleiche gilt für anders codierte Sendesignale. Die Selektion erfolgt also hauptsächlich im Decoder. ,Poor selection of the receiving part or interference on the receiving frequency itself are ignored. The same applies to differently coded transmission signals. The selection therefore takes place mainly in the decoder. ,
Mit einem Impuls angesteuert, würde die Leuchtdiode (5) nur kurz aufblinken. Deshalb ist ihr noch eine bistabile Kippstufe (4) vorgeschaltet.If triggered by a pulse, the LED (5) would only flash briefly. This is why a bistable flip-flop (4) is connected in front of it.
Jeder Schaltimpuls vom Decoder läßt die Kippstufe "umspringen", von "Leuchtdiode aus" auf "Leuchtdiode ein" und umgekehrt.Each switching pulse from the decoder causes the flip-flop to "jump" from "LED off" to "LED on" and vice versa.
Alle elektronischen Teile werden von zwei Batterien gespeist.All electronic parts are powered by two batteries.
Als Leuchtmittel wurde eine Aluminium - Indium - Gallium - Arsenid - Phosphor - Leuchtdiode verwendet. Leuchtfarbe: gelb (590 nm Wellenlänge), ca. 9300 mcd maximale Lichtstärke. Diese erhielt einen Mantel aus durchscheinendem Kunststoff (Kunstharz) in Form einer Kerzenflamme, ist also mit flüssigem Kunststoff (der dann aushärtet) umgössen.An aluminum - indium - gallium - arsenide - phosphor - light-emitting diode was used as the light source. Light color: yellow (590 nm wavelength), approx. 9300 mcd maximum light intensity. This was given a coating of translucent plastic (synthetic resin) in the shape of a candle flame, i.e. it is surrounded by liquid plastic (which then hardens).
