However, if power is supplied through a socket or the like as described above, for example, when a user tries to change the position and number of light bulbs, it is necessary to change the position and number of sockets from which power is extracted. To that end, it is not easy to disconnect and reconnect the wiring once, and it is not easy. Also, since the socket and the like have direct electrical contact with the wiring, There is a risk of accidents due to factors. Accordingly, the present applicant provides a magnetic body provided with a winding in the vicinity of a wiring through which an alternating current flows, and uses the current that is electromagnetically induced in the winding to cause the light emitting unit to emit light.

It is different from the first light emitting means 20 in that it is provided in the vicinity, and the other configuration is the same as that of the first light emitting means 20.
[0038]
Next, the action of causing the first light emitting means 20, the second light emitting means 25, and the third light emitting means 27 to emit light in the present lighting device will be described.
[0039]
First, the oscillation circuit 41 is driven by the DC power source 40 to generate a signal having a predetermined frequency. The signal generated by the oscillation circuit 41 is input to the frequency dividing circuit 42. The frequency dividing circuit 42 divides the input signal based on the frequency-divided signal Qn and the frequency-divided signal Qn for dividing the input signal to a desired frequency. The signals Qm and Qp for controlling the output of the received signals are output to the first control means 43 and the second control means 44. The first and second control means 43 and 44 output a signal having a desired period for a desired time based on the input frequency-divided signal Qn and the signals Qm and Qp.
[0040]
The alternating current output from the first control means 43 is passed through the first wiring 10. FIG. 7A shows a voltage waveform of an alternating current flowing through the first wiring 10 in the present embodiment. As shown in FIG. 7A, the first control means 43 outputs an ON signal having a period t1 based on the frequency-divided signal Qn for a desired time, and the times T1 to T4 are determined by the signals Qm and Qp. It is time to be.
[0041]
In addition, the alternating current output from the second control unit 44 is passed through the second wiring 15. A voltage waveform of the alternating current flowing through the second wiring 15 is shown in FIG. Similar to the first control unit 43, the second control unit 44 outputs an ON signal having a period t1 based on the frequency-divided signal Qn for a desired time, as shown in FIG. 7B. The output of the alternating current can be controlled so that the time during which the ON signal is output is different from the alternating current that flows through the first wiring 10. For example, as shown in FIGS. 7A and 7B, the first and second control means 43 and 44 are connected so that an ON signal is output only to the first wiring 10 during time T1. The output of the current is controlled, the output of the alternating current is controlled so that the ON signal is output only to the second wiring 15 during the time T2, and the first wiring 10 and the second wiring are controlled during the time T3. It is possible to control the output of the alternating current so that the ON signal is output to both of them. Further, the first and second control means 43 and 44 can output so that the phases of the ON signals output from each other are different. For example, as shown in FIGS. During this period, the ON signals output from each other can be output so as to be shifted by a half cycle.
[0042]
The alternating current passed through the first wiring 10 passes through a hollow portion constituted by the first magnetic body 22 and the second magnetic body 23 in the first light emitting means 20. The bidirectional current induced electromagnetically flows through the windings 21a, 21b, 21c, and 21d of the first magnetic body 22 and the second magnetic body 2 due to the passage of the alternating current. When bidirectional current flows through the windings 21a, 21b, 21c, and 21d, a voltage is generated in the copper wires 30a and 30b connected to both ends of the winding 21a. A bidirectional current also flows through the copper wire 31 based on this voltage. A bidirectional current having a waveform corresponding to the waveform of the alternating current flowing in the first wiring 10 flows in the copper wire 31.
[0043]
As shown in FIG. 3, a light emitting unit 32 is connected to the copper wire 31, and light can be emitted by supplying the bidirectional current to the light emitting unit 32 to supply power.
[0044]
In addition, when an alternating current is passed through the second wiring 15 in the same manner as described above, a bidirectional current also flows through the copper wire 31 of the second light emitting means 25, whereby the light emitting portion 32 of the second light emitting means 25. To emit light. The waveform of the bidirectional current flowing through the second light emitting means 25 is a waveform corresponding to the waveform of the alternating current flowing through the second wiring 15.
[0045]
In addition, by passing an alternating current through the first wiring 10 and the second wiring 15 as described above, a bidirectional current also flows through the copper wire 31 of the third light emitting means 27, whereby the third light emitting means. 27 light emitting units 32 emit light. As shown in FIG. 7C, the waveform of the bidirectional current flowing through the third light emitting means 27 is the waveform of the alternating current flowing through the first wiring 10 and the waveform of the alternating current flowing through the second wiring 15. Corresponding waveform.
[0046]
Therefore, by passing an alternating current through the first wiring 10 and the second wiring 20 at the timing shown in FIG. 7, only the first light emitting means 20 and the third light emitting means 27 are allowed during the time T1. During the time T2, only the second light emitting means 25 and the third light emitting means 27 emit light, and during the time T3, all of the first to third light emitting means 20, 25 and 27 are emitted. , And only the first light emitting means 20 and the second light emitting means 25 emit light during time T4. Note that the third light emitting means 27 does not emit light during the time T4 because the alternating current flowing through the first wiring 10 and the alternating current flowing through the second wiring 15 have the ON signal cycle as described above. As a result, the magnetic field formed by the alternating current flowing through the first wiring 10 and the magnetic field formed by the alternating current flowing through the second wiring 15 cancel each other, resulting in the third This is because a bidirectional current does not flow through the light emitting means 27 or only a very weak bidirectional current flows.
[0047]
Moreover, in the said embodiment, as shown in FIG. 8, the 4th light emission means 50 is further provided, and the direction of the alternating current which flows through the 2nd wiring 15 which passes the 4th light emission means 50 is made into the 2nd light emission means. The direction of the alternating current flowing through the second wiring 15 passing through the 25 and the third light emitting means 27 may be reversed. With the configuration described above, the direction of the magnetic field generated according to the alternating current flowing through the second wiring 15 in the fourth light emitting unit 50 is reversed. Therefore, when the same alternating current as the waveform shown in FIGS. 7A and 7B is caused to flow through the first wiring 10 and the second wiring 15, the fourth light emitting means 50 has the time T1, Light is emitted during time T2 and time T4, and no light is emitted during time T3.
[0048]
According to the electrical decoration device 2, the power supply device 1 is configured to pass alternating currents having different phases through the first wiring 10 and the second wiring 15, and the wirings of the first wiring 10 and the second wiring 15. The first light emitting means 20 and the second light emitting means 25 are provided in the vicinity of each wiring so that light is emitted by a bidirectional current corresponding to only the alternating current flowing through the first and second wirings 10 and 15. Since the third light emitting means 27 is provided in the vicinity of the first and second wirings 10 and 15 so as to emit light by a bidirectional current corresponding to the alternating current flowing through the second current, the third light emitting means 27 The timing of light emission can be controlled at a timing different from that of the first and second light emitting means 20 and 25 provided on each of the wirings, resulting in an increase in the size and cost of the apparatus due to the addition of wiring and control circuits. It is possible to increase the light emission pattern of the light emitting means without the.
[0049]
Further, in the above embodiment, since the light emitting means can be attached to and detached from the wiring, the position and the number of the light emitting means can be changed more easily.
[0050]
Further, in the above embodiment, the first wiring is obtained by shifting the phase of the alternating current flowing through the first wiring 10 and the alternating current flowing through the second wiring 15 by a half cycle or by reversing the direction in which the alternating current flows. 10 and the light emission of the light emitting means provided in the vicinity of the second wiring 15 is controlled. However, the present invention is not limited to this, and the alternating current flowing through the first wiring 10 and the second wiring 15 are not limited to this. The phase of the flowing alternating current may be different, and thereby the light emission of the light emitting means may be controlled.
