  • the molten wax 9 flows into and retained by the upper part 5 a of the cover 5 through the openings 19, 22.
  • the spring 6 relaxes and pushed the body 3 upwards in such a manner that the surface level of the molten wax 9 is maintained substantially constant and without overflowing the cover 5.
  • the casing 1 of the candle device maintains its external appearance throughout the burning of the candle, and can be used with replaceable wax bodies 3.
  • a compartment 7 is formed at the bottom of the casing 1 for accommodating a music generator 15, the compartment is closed from below by a lid 7 ⁇ .
  • the music generator operates to play music in response to the burning of the candle.
  • the music generator 15 comprises an integrated circuit IC, a d.c. battery V, a piezo-electric crystal loudspeaker SP, and switching means 13.
  • the integrated circuit IC has a memory storing one or more musical tunes. It is electrically connected to a loudspeaker SP, a battery V, and switching means 13. When an appropriate signal to is applied the integrated circuit IC from switching means 13, the integrated circuit IC is triggered to provide an electical output signal corresponding to one of the stored musical tunes to drive the speaker SP.
  • the switching means 13 is arranged to trigger the integrated circuit IC in response to the presence of a candle flame 8 at the wick 4 when the candle is burning.
  • the switching means 13 may comprise a photo-sensitive resistor R which detects the presence of the candle flame 9 by means of an elongate fibre optic 19 extending from the region of the upper end of the candle wick 4.
  • the fibre optic 19 may extend between the casing 1 and the lining 2, as shown in Figure 1, or extend along side candle wick 4, both being embedded in the wax body 3.
  • the photo-sensitive resistor R may be mounted at the top of the casing 1 so that light from the candle flame 8 will fall directly on the resistor R.
  • a second type of the switching means 13 may include a thermo-senstivie resistor R ⁇ which detects the presence of the candle flame 8 by means of a thermally conducting wire 19 ⁇ which extends along a similar path to the fibre optic 19, the resistor R ⁇ may be placed in the vicinity of the candle flame.
  • the thermally conducting wire 19 ⁇ is used, it is preferably heat insulated along its length so as not to damage or melt other parts of the candle device.
  • thermo-sensitive resistor In place of the thermo-sensitive resistor, infra-red sensitive diode may detect infra-red radiation given off by the heated wire.
  • FIG. 3 shows a third type of the switching means 13 which includes a pressure sensitive switch 21.
  • a sealed container 23 is closed at one end 23 a by a flexible or elastic membrane 24, and contains thermally expansible material 25, for example air.
  • a thermally conducting wire 26 extends from the region of the candle flame 8 into the other end 23 b of the container 23 where the wire 26 is laid as a flat spiral 26b on a thermally insulating plate 27. Head from the candle flame passes along the wire 26, to heat the material (air) 25 which thus expands and bows the membrane 24 outwards.
  • the pressure sensitive switch 21 comprises movable and stationary contacts 28 a and 28 b .
  • the movable contact 28 a is located on the membrane 24, and is arranged to contact the stationary contact 28 b when the membrane 24 is sufficiently bowed.

  • Figure 5 shows a modification of the embodiment of figure 4 in which several switch contacts 28b ⁇ are arranged along the cylinder 23. As the temperature of the air 25 increases the piston is pushed further along the cylinder and contact 28a ⁇ makes contact with each contact 28b ⁇ in turn. Each contact 28b ⁇ forms an input to the IC, and the IC is arranged to play a number of different tunes. As contact is made between contact 28a ⁇ and each contact 28b ⁇ in turn a different tune is played by the IC.

  • the copper (11) sulphate crystals contacts 43 are fixed in the tube at intervals along its length.
  • the opposed contacts form plates of a capacitor. As the water reaches the contacts, the capacitance between them changes, and this can be detected by the IC, to trigger the IC to play a tune.
  • Each contact is preferably arranged to trigger the playing of a different tune, or the same tune may be repeated.
  • Apertures 44 in the top of the tube allow for the water to evaporate after use, so that the switch reusable.
