BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative lamp mounted on the side of an altar or on a table such as a dining table, and particularly simulates the unique flickering lighting effect of a candle flame as much as possible. The present invention relates to a decorative lamp that can be used.

[0002]

2. Description of the Related Art Conventionally, candles have long been widely used as religious ceremonies and desk lighting fixtures due to the unique glowing and fluctuation effects of the flame. It has the drawbacks of being unsuitable for lighting for a long time due to consumption, and the fact that the flame easily disappears due to the movement of air. A simulated one is proposed.

However, in this case, although the above-mentioned drawbacks are eliminated, when it is used as a decorative lamp by placing it on the side of an altar or on a table such as a dining table, only a uniform lighting effect of a fixed lighting lamp is obtained. Then, as an incandescent lamp or fluorescent lamp, there is no difference as a lighting accessory,
It was far from being able to reproduce the unique glow effect of candles.

[0004]

On the other hand, the applicant of the present invention is
In the research process for adding a dynamic lighting effect to a decorative lamp, by combining the above-mentioned lighting lamp with an electromagnet widely adopted as an element of various machines, devices, etc. Focusing on the fact that the glow effect and the fluctuation effect can be easily reproduced by keeping a calm atmosphere without running brilliantly, it is unsuitable for lighting for a long time due to emission of burning smoke and consumption of wax. Recognizing that it is possible to create a lighting effect that matches the modern sensation even more, while eliminating the drawbacks such as the flame easily disappearing due to the movement of, we have completed a new decorative lamp here.

[0005]

In order to solve the problems, a technical means adopted by the present invention is to provide a hollow body formed in a long cylindrical shape with an electromagnet and an oscillating circuit for intermittently exciting the electromagnet. In addition, the iron weight with the lighting lamp attached is supported in a floating manner by facing the magnetic field of the electromagnet, and the light emitting portion of the lighting lamp is projected from the upper surface of the tip of the hollow body to light in cooperation with repeated intermittent excitation of the electromagnet. It is characterized in that the lamp is configured to swing in an irregular direction.

[0006]

Therefore, according to the present invention, it is possible to faithfully reproduce the glow effect and the fluctuation effect due to the flame of a candle, and to induce the viewer with a calm and religious feeling while maintaining a calm atmosphere. Therefore, it is possible to create a unique glow effect that is not present in conventional ornamental lighting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings. In FIG. 1, reference numeral 1 is a decorative lamp, and the decorative lamp 1 is a hollow body 2 formed in a long tubular shape.
The lighting lamp 3 evoking the flame of a candle is projected at the tip of the and the screwed terminal 4 for connecting the AC power source is attached to the bottom to simulate the shape of the candle.

In the hollow body 2, as shown in FIGS. 2 (a) and 2 (b), capacitors C1 to C2 forming an oscillation circuit 6 to be described later are provided on a substrate 5 having a wiring pattern surface 5a formed on the back surface. , Resistors R1 to R6, diodes D1 to D2, PUT
Electrical elements of a (programmable single junction transistor) and a transistor Q are arranged, and an electromagnet M is mounted with its iron core m protruding upward.

As shown in FIG. 3, a supporting portion 7 having a circular pedestal 7a is attached to the upper edge of the substrate 5 so as to be orthogonal to the surface of the substrate 5, and the socket 8 of the lighting lamp 3 is attached.
At the lower end of the swing rod 9 that hangs down, an iron weight 10 is mounted on the pedestal 7a.
It is attached in a loose fit shape by penetrating through the insertion hole 7b.

A power supply line 1 having one ends 11a and 12a connected to the wiring pattern surface 5a of the substrate 5 is attached to the swing rod 9.
Nos. 1 and 12 are coaxially inserted in a coiled state, and while holding the iron weight 10 between the pedestal 8a integrally formed on the lower surface of the socket 8 and the pedestal 6 of the support portion 7, The other ends 11b and 12b of the power supply lines 11 and 12 are connected to the contacts 14 and 14 of the socket 8 through the through holes 13 and 13 formed in the socket 8 to supply AC power to the lighting lamp 3. Is configured.

Next, the oscillator circuit 6 shown in FIG. 4 will be described. In the figure, R1, D1 and C1 constitute a half-wave rectification circuit, and the rectified drive voltage is R
C2 is charged through 2 and the PUT is ignited when this charging voltage exceeds the threshold voltage divided by R3 and R4, and the bias voltage generated in R5 by the ignition of the PUT is used as the base voltage. Transistor Q via bias resistor R6
Is configured to supply.

That is, when the charging voltage of C2 becomes equal to or lower than the threshold voltage due to the ignition of PUT, the oscillator circuit 6 outputs
The UT is turned off, C2 is gradually charged during this off period, and when this charging voltage reaches the threshold voltage or more again,
The transistor Q is repeatedly operated by the PUT being ignited.
ON / OFF control is performed, and the excitation and de-excitation of the electromagnet M is repeatedly performed. D2 is a protection diode that absorbs the transient voltage generated in the electromagnet M.

In the above construction, when the screw-in terminal 4 of the decorative lamp 1 is attached to the socket of a stand (not shown) to which an AC power source is connected and the power switch is turned on, the lighting lamp 3 emits light and oscillates. Power is supplied to the circuit 6. Here, in the oscillation circuit 6, the transistor Q is turned on and off by the repeated firing of the PUT, but the iron core m of the electromagnet M is excited while the transistor Q is in the on state, that is, while the emitter and the collector are conducting. During this excitation period, the iron weight 10 is attracted to the iron core m side against the elastic force of the coil-shaped power supply lines 11 and 12, and the transistor Q is in the OFF state, that is, the emitter and the collector are in the conductive state. When the electric magnet M is de-excited when the electric power is changed from the non-conduction state to the non-conduction state, the iron weight 1 is caused by the elastic force of the power supply lines 11 and 12.
0 is supposed to bounce away from the iron core m,
The iron weight 10 is swung in the vertical direction. As the iron weight 10 swings in the vertical direction, as shown in FIG.
The lighting lamp 3 mounted on the socket 8 at the tip of the swinging rod 9 through the swinging rod 9 loosely fitted into the insertion hole 7b of the swinging rod 7b is irregular around the vertical movement while maintaining the light emitting state. It is pushed up in the direction. Therefore, by swinging the lighting lamp 3 in an irregular direction, the fluctuation effect of the flame of the candle is faithfully reproduced, and it is possible to exhibit a unique glow effect while maintaining a calm atmosphere without running brilliantly. it can.

Further, FIGS. 6 and 7 show a combination of an oscillation circuit 6 for pulse generation in which NE555 known as an IC timer is destabilized, a transistor Q and a DC electromagnet M, and a hollow battery 2 using a small battery 15 as a driving power source. The structure shown in FIG.
By adjusting the pulse width and frequency by changing the constant of the capacitor C, the exciting and non-exciting intervals of the electromagnet M can be changed, and the fluctuation of the lighting lamp 3 can be changed. Further, by using a battery as the driving power source, it is possible to use it without having to circulate the power cable as in the above-mentioned embodiment, for example, when walking while holding the decorative lamp 1 in hand, While improving portability, it can be used under the same usage conditions as conventional candles. Instead of the IC timer having the above configuration, a simple oscillator circuit 6 may be configured by combining two inverter elements connected in series and a time constant circuit of a resistor and a capacitor. In this case, since the number of elements forming the oscillation circuit 6 is small, the decorative lamp 1 can be formed more compactly.
