Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a decorative appliance, and more particularly to a decorative wireless lighting appliance that supplies power through electromagnetic induction.

Normally, in a two-winding type transformer, the primary winding and the secondary winding are not electrically connected and are insulated, but by applying an alternating current voltage to the primary winding, the Voltage is induced in the next winding and voltage transformation can be performed. Therefore, if we use the electromagnetic induction phenomenon, which is the principle of a transformer, for lighting equipment,
The lamp can be lit without a power supply line.

This idea was created in view of the points mentioned above, and it is a novel decorative device that can supply electricity by electromagnetic induction without using a power supply line, and can flicker while swinging the lamp. The purpose is to provide decorative wireless lighting equipment.

This idea can be summarized as follows: a lamp is provided at one end;
It has a coil winding part connected to the lamp at the other end, a rocking shaft having a rocking balancer attached to its approximately central portion, and a rocking shaft that is swingably supported approximately at its central portion. The lamp is characterized in that it includes a support shaft and a high frequency oscillation section disposed opposite to the coil winding section, and the lamp is lit by electromagnetic coupling between the coil winding section and the high frequency oscillation section.

FIG. 1 is an external view of a decorative wireless lighting fixture that is an embodiment of this invention, and FIG. 2 is a structural diagram showing the electromagnetic coupling state between the coil winding part and the high-frequency oscillation part of the lighting fixture.

As shown in Fig. 1, a roughly spherical capsule 2 with a flange made of Japanese paper, translucent plastic, etc. is attached to one end of the swing shaft, which is made of a single somewhat flexible circular tube. It is worn. A socket in which a wheat bulb lamp (not shown) having a rated voltage of approximately 100 volts is mounted is fixed inside the capsule 2. Attached to the other end of the swing shaft 1 is a coil winding section 3 in which a coil wound multiple times is loaded into a bottomed cylindrical case. The coil terminal of the coil winding part 3 and the socket for the wheat bulb lamp in the capsule 2 are connected by a power line inserted into the circular tube of the swing shaft 1. At approximately the center of the swing shaft 1, a bow-shaped balance shaft 4a is attached to which a swing balancer 4 made of iron balls is fixed. Further, a slightly lower portion of the swing shaft 1 to which the balance shaft 4a is attached is supported by the tip of a support shaft 5 that stands vertically from the center of a cylindrical support base 5a.
The support point of the swing shaft 1 with the support shaft 5 is the center of gravity of the swing shaft 1 to which the capsule 2, the coil winding portion 3, and the swing balancer 4 are attached. The center of gravity of the swing shaft 1 is supported by a triangular metal fitting attached to the center of gravity by a conical metal fitting rotatably attached to the tip of the support shaft 5. There is. The support base 5a that swingably supported these capsules 2, etc.
The table has a built-in high-frequency oscillation section, etc., and is placed on a circular table 6 whose surface is mirror-finished. By placing the support column 5a on the table 6, the coil winding section 3 and the high frequency oscillation section 7 in the table 6 are placed in an opposing positional relationship as shown in FIG. That is, the secondary coil 3a of the coil winding section 3 and the primary coil 7 of the high frequency oscillation section 7
A magnetic coupling is formed with a space between the two and a. The degree of magnetic coupling is determined by the primary coil 7a.
It is proportional to the coupling rate determined by the closeness of the secondary coil 3a and the secondary coil 3a, and is expressed by the magnitude of mutual inductance.

In the above configuration, first, the high frequency oscillator 7 in the table 6 is activated while the swing shaft 1 is stationary.
is driven, the secondary coil 3a of the coil winding part 3
A voltage is induced in the capsule 2 by electromagnetic induction.
The wheat bulb lamp inside lights up. Therefore, when the wind generated by an electric fan or the like is applied to capsule 2,
The swing shaft 1 loses its balance and swings like a pendulum, as shown by the dotted line in FIG. 1, and rotates slightly around the support shaft 5. By swinging the swing shaft 1, the coil winding portion 3 approaches or moves away from the surface of the table 6. Therefore, the degree of magnetic coupling between the secondary coil 3a of the coil winding section 3 and the primary coil 7a of the high frequency oscillation section 7 built in the table 6 changes by becoming denser or sparser. That is, when the degree of magnetic coupling becomes dense, the coupling rate increases and a large voltage is induced in the secondary coil 3a. When the degree of magnetic coupling becomes weak, the coupling rate is small and the voltage induced in the secondary coil 3a is small. The wheat bulb lamp inside the capsule 2 flickers depending on the magnitude of the voltage induced in the secondary coil 3a.
The wheat bulb lamp becomes brightest when the coil winding portion 3 is closest to the surface of the table 6. At this time, the swing balancer 4 is in contact with the cylindrical side surface of the support column 5a. The swing balancer 4 maintains the swing balance of the swing shaft 1 to which the capsule 2 is attached, and also works as a stopper by coming into contact with the support column 5a when the swing amplitude reaches its maximum. Also,
The balance shaft 4a to which the swing balancer 4 is fixed is
Since it has an arcuate shape that surrounds the support shaft 5, it will not come into contact with the support shaft 5 due to swinging.

In this way, the capsule 2 is
rotates and changes its position while rocking, and the wheat bulb lamp inside the capsule 2 automatically flashes and its brightness is adjusted according to the rocking. Furthermore, if this decorative wireless lighting device is installed in a dimly lit place and the wheat bulb lamp is used as a multicolor light source, the decorative effect as a decorative device will be novel and even greater.

As described above, according to the decorative wireless lighting fixture of this invention, power is supplied to the coil winding part by electromagnetic induction from the high frequency oscillating part disposed opposite to the coil winding part, so the decorative wireless lighting equipment The power supply line exposed to the outside, which is not very desirable, can be removed. Moreover, since the lamp is equipped with a lamp at one end and a coil winding portion connected to the lamp at the other end, the lamp is lit while swinging a swing shaft to which a swing balancer is attached approximately in the center. The advantage is that the lamp can be automatically blinked without any complicated attachments in response to changes in the electromagnetic coupling ratio between the coil winding section and the high-frequency oscillation section, producing novel and effective light as decorative light. has.
