Therefore, one light emitting element 18 is located outside the magnetic body 16. These components are integrally molded by an exterior body 22 made of resin or the like.

  As shown in FIG. 6, the width of the magnetic body 16 of the light emitting unit 15 in the direction orthogonal to the longitudinal direction of the power feeding unit 1 is smaller than the width of the opening of the exterior body 8 of the power feeding unit 1. The width of the 15 exterior bodies 22 in the same direction is substantially the same as the opening of the exterior body 8 of the power feeding unit 1, and engaging projections 23 are provided at both ends in the width direction.

Since it is sandwiched, an induced current is generated and the light emitting element 18 is turned on. However, since the receiving coil 17 of the other light emitting portion 15B is sandwiched between the wiring portions L2 and L3 in which the direction of the flowing current is always the same direction, no induced current is generated and the light emitting element 18 is not lit.

  That is, whether or not the light emitting element 18 of the light emitting unit 15 attached to the power feeding unit 1 emits light depends on which of the wiring parts of the power feeding coil 5 the power receiving coil 17 of the light emitting unit 15 is inserted. The light emitting state (lighting or non-lighting) of the light emitting element 18 can be determined by arbitrarily determining the mounting posture of the light emitting unit 15 with respect to the power feeding unit 1.

It is a waveform diagram.

  The electrical decoration device of this example includes a power supply unit 1 ′ having a common power source 2 and two systems of power supply coils 5 ′ and 5 ″, and a light emitting unit 15 having the same configuration as that of the first example (preparing the required number). The positional relationship between the power receiving coil 17 of the light emitting unit 15 and the power feeding coils 5 ′ and 5 ″ of the power feeding unit 1 ′ is changed by changing the position where the light emitting unit 15 is attached to the power feeding unit 1 ′. The light emitting element 18 is turned on or off by selecting whether or not electric power is induced in the power receiving coil 17, or the mounting positions of the light emitting units 15 ′ and 15 ″ with respect to the power feeding unit 1 ′ are changed. The driving of the power feeding coils 5 ′, 5 ″ is changed while being constant, and the light emitting element 18 is turned on or off by selecting whether power is induced in the power receiving coil 17 of the light emitting unit 15 or not. It is to switch.

  As shown in FIG. 7, the power supply unit 1 ′ includes a common power source 2 (power source 2 circuit or battery), an oscillation circuit 3 that generates a signal serving as a reference for the drive signal, and an oscillation circuit 3 as necessary. A frequency dividing circuit 4 that converts a signal into a drive signal based on the signal, a control circuit 25 that outputs a control signal based on a signal from the frequency dividing circuit 4, and a drive circuit that is controlled by the control circuit 25 to drive the first feeding coil 5 ′. And a second drive circuit 6 "that is controlled by the control circuit 25 to drive the second power supply coil 5".

  These two systems of feeding coils 5 ′ and 5 ″ are closed loop coils having both ends connected to the respective drive circuits 6 ′ and 6 ″ as shown in FIG. 7, and differ depending on the crossing arrangement. The wiring portions belonging to the feeding coils 5 ′ and 5 ″ are alternately adjacent to each other and arranged so as to be parallel to each other at a predetermined interval.

  Accordingly, assuming that the four linear wiring portions are L1, L2, L3, and L4 in this order, when the two power supply coils 5 ′ and 5 ″ are driven with alternating current of opposite phases, the wiring portions L1, L2, and L2 The direction of the current flowing in L3 and L4 is always opposite in L1 and L2, always in the same direction in L2 and L3, and always opposite in L3 and L4. ”Is driven with the same phase alternating current, the directions of the currents flowing through the wiring portions L1, L2, L3, and L4 are always the same in L1 and L2, are always opposite in L2 and L3, and L3 and In L4, the direction is always the same.

As shown in FIG. 7, the case where the light emitting unit 15 is provided between the wiring portions L1 and L2 and between the wiring portions L2 and L3 (that is, a total of two) is driven as shown in FIG.
As shown in the first half of the timing diagram of FIG. 8, the phase of the drive signal that the first drive circuit 6 ′ gives to the first power supply coil 5 ′ and the second drive circuit 6 ″ are the second power supply coil 5 ″. When the phase of the drive signal applied to is reversed, an induced current is generated in the power receiving coil 17 of the first light emitting unit 15A and the light emitting element 18 emits light, but the power receiving coil 17 of the second light emitting unit 15B has An induced current is not generated and the light emitting element 18 does not emit light.

  Conversely, as shown in the second half of the timing diagram of FIG. 8, the control by the control circuit 25 is switched, and the phase of the drive signal that the first drive circuit 6 ′ gives to the first power supply coil 5 ′ and the second drive When the phase of the drive signal applied to the second power supply coil 5 ″ by the circuit 6 ″ is the same, no induced current is generated in the power receiving coil 17 of the first light emitting unit 15A, and the light emitting element 18 does not emit light, but the second An induction current is generated in the power receiving coil 17 of the light emitting unit 15B, and the light emitting element 18 emits light.

  As described above, when two light emitting units 15A and 15B are provided at two positions of the power feeding unit 1 ′ having different electromagnetic induction conditions, the AC phases applied to the two power feeding coils 5 ′ and 5 ″ are the same. By selecting whether to perform or not, it is possible to determine which of the light emitting units 15A or 15B emits light or not, that is, the light emitting units 15A and 15B attached to the power feeding unit 1 ′. Without changing the position, the light emitting state of the light emitting element 18 can be changed only by changing the control of the drive circuits 6 ′, 6 ″ in the control circuit 25. Of course, as in the first example, the difference in the phase of the alternating current applied to the two power supply coils 5 ′ and 5 ″ is fixed, and the light emitting element depends on the mounting position of the light emitting units 15A and 15B with respect to the power supply unit 1 ′. It is also possible to determine the light emitting state of 18. Further, the control circuit 25 performs the switching so that the above-described control is performed at high speed so that the light emitting elements 18 of the two light emitting units 15A and 15B are simultaneously turned on. You can also.

In this example, the position between the wiring portions L3 and L4 was not taken up as the position where the light emitting unit 15 is attached. However, as can be seen from the above description, the power receiving coil 17 is arranged between the wiring portions L3 and L4. The light emitting part 15 attached to the power feeding part 1 ′ has the same conditions in terms of electromagnetic induction as the light emitting part 15A attached between the wiring parts L1 and L2 in the explanation of the above example, and is used according to the above explanation. be able to.
Other actions and effects can be considered substantially the same as in the first example. The same components as those in the first example are denoted by the same reference numerals as those in the first example, and description thereof is omitted.

  Further, in this example, the two power feeding coils that are driven independently of each other are arranged in a partially overlapped state. However, a plurality of power feeding coils as in this example are arranged at an appropriate interval without crossing them. It is good also as a structure arrange | positioned so that each wiring part may become parallel. In such a configuration, if the AC drive signal applied to each power supply coil is selectively switched so that the phase of the AC drive signal is the same or opposite, the current direction of the two wiring portions sandwiching the power receiving coil is at least one. Since it can be set to be the same or reverse in the part, lighting or non-lighting of the light emitting element can be switched in the part.

An induction current is generated in the second power receiving coil 17B, and this time, the first light emitting element 18 is not lit and only the second light emitting element 18 emits blue light. If the light emitting unit 15 ′ is removed from the power feeding unit 1, none of the light emitting elements 18 emits light.

  Thus, in this example, since the light emitting color of the light emitting element 18 connected to each of the two power receiving coils 17A and 17B is different, the mounting direction of the light emitting unit 15 ′ is not changed without changing the driving of the power feeding unit 1 ″. The light emission color can be selected simply by changing the above, and the other actions and effects can be considered substantially the same as in the first and second examples.

According to the electrical decoration device according to the embodiment of the present invention described above, no mechanical electrical contact is required, and various light emission conditions such as arrangement of light emitting elements, lighting / non-lighting, color when light is emitted, and the like can be arbitrarily set. In any field where there is a desire to set, the light emitting section can be freely replaced or rearranged, and the illumination effect can be improved. The use is not particularly limited, but if an example is given, lighting such as a step light provided in a passing part in a building, a guide light provided on a wall surface, an emergency guide light or a guide light provided in a passing part in a vehicle, a road It can be effectively used as illumination such as a guide light provided on the traveling surface of the vehicle.
In particular, in the above-described applications, when the power feeding portion fitted with the light emitting portion is provided on the mounting surface, the opening of the outer casing of the power feeding portion and the light emitting surface of the light emitting element of the light emitting portion coincide with the mounting surface. If the power supply part is embedded in the mounting surface, and the part without the light emitting part of the power supply part is covered with another lid, it has a unique effect that it looks good, does not easily break down, and is convenient to handle. Can also be obtained.
