Definitions

  • the present invention relates to electrical Christmas tree lights that can be operated without a cable connection.
  • Christmas tree candles have long been used as lights.
  • candle-shaped electric lamps have been used instead of wax or stearin candles.
  • Such candles have so far been practically exclusively implemented as so-called fairy lights.
  • This is essentially a series connection of many lamps, the individual operating voltage times the number of which enables direct connection to the electrical network. This makes wiring particularly easy, however the number of lamps per chain of lights is fixed; in particular, due to the series connection, all lamps must always be on at the same time.
  • the cable connection leading from candle to candle is not only unattractive, it is also prone to failure, for example, against stumbling, tearing off etc.
  • the cable of a chain of lights operated directly on the mains is always at least at one end with the mains voltage typically 230V to earth. This possible danger can be eliminated by isolating transformer, fault current indicator and the like, but is usually present in the inexpensive fairy lights.
  • LEDs light-emitting semiconductor diodes
  • the efficiency of such light-emitting diodes is many times higher than that of the light bulbs usually used.
  • white LEDs are already available today, which deliver a luminous flux of more than 7 cd at a voltage of 4 V and 25mA current consumption. This brings battery-operated Christmas tree candles into practical feasibility, since commercially available components can be used to achieve a useful burning time, brightness with the usual size, dimensions and weight.
  • the present invention is based on the recently available, inexpensive availability of such LEDs.
  • the proposal provides for a cylindrical lamp modeled on a candle, which has one or more highly efficient light-emitting diodes (white / yellow) at its tip, which emits the light emitted into an opaque plastic structure modeled on a conventional candle flame.
  • This simulated "flame" can either be opaque, it can also have red / yellow or darker areas that mimic a wick structure, etc.
  • the required operating voltage of a white-emitting LED is at least 3 to 4V. Either a lithium battery or three NiH rechargeable batteries connected in series or the like is necessary for this.
  • the weight also plays a major role for the energy storage device: the shape and weight of the electric candle should match a real Christmas tree candle if possible. The price is also crucial.
  • the energy required should either be by a Li-ion cell, by three NiCd or NiH battery cells connected in series, or preferably and for reasons of price by only a single NiH mono cell (size AAA, approx. 9 mm in diameter) 40mm length, or a slightly larger mignon cell).
  • the stored energy is in the range of typically 500,900 mWh. This is sufficient for several hours of operation.
  • a single mono cell plus electronics is currently cheaper than three cells or a Li-ion cell. This applies above all because an efficiently operated LED anyway requires a regulated voltage or a precisely limited current for its operation. An electronic circuit can do this most efficiently.
  • the electronics can also contain other integrated components: On the one hand, this is an automatic flicker: The illuminance is modulated slightly and over a long period in order to come close to the impression of a natural candle.
  • a remote control can be integrated, which is implemented in the usual way by means of an infrared photodiode or also by means of an ultrasound receiver.
  • Implementation using the mass-produced infrared remote control is particularly inexpensive.
  • the opaque flame imitation which collects the light from the IR transmitter and transmits it to a photodiode in the candle, can serve as the receiving element.
  • the modulation customary in such remote control lines reliably prevents interference from the white LED.
  • the remote control avoids an externally operable switch for switching on / off. Automatic loading is also to be integrated. Since an electrical energy of typically about 50.150mW is required to produce the brightest possible impression of light, which is equivalent to a conventional wax candle, operation using a rechargeable battery makes more sense than that on a primary cell.
  • the automatic charging should enable the charging of this battery located in the candle contactlessly via an HF power supply (typically 100 kHz) without a galvanic connection, i.e. contactless.
  • HF power supply typically 100 kHz
  • contactless a galvanic connection
  • the additional effort integrated in the electronic circuit is less than that for a version with contacts, openings, etc.
  • a coil is provided which is essentially placed around the monocell and which takes the energy from an HF field of a charger.
  • the structural material of the battery is made of metal and would short-circuit or significantly attenuate the RF field of the pick-up coil; In order to prevent this, a magnetic shield (amorphous iron foil) known to the person skilled in the art is provided.
  • Such an electrical, battery-operated Christmas tree candle has the following advantages: - No fire risk
  • candles can be used individually
  • a disadvantage is the higher price of such a candle compared to light bulbs connected in series, which is currently at a production price of typically 2 to 3 euros, but with a downward trend.
