Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a decorative unit, in which a light emitting body, its lighting control circuit section, a power supply section, etc. are integrated into a unit with a rod-shaped main body case as the main body.

(Background of the invention) Devices in which light-emitting bodies emitting light of different colors are lit are known as various ornaments, display devices, or interior decoration devices. However, the usage of this type of conventional decoration device is limited and it is difficult to use it for a variety of purposes.For example, this type of decoration device for Christmas trees can be used as a decoration means for other ornaments, display devices, etc. There were problems such as it was difficult to repurpose, and it was troublesome to handle and store.

(Purpose and Structure) The present invention has been made in view of the above circumstances, and can be applied to various purposes as various ornaments, display devices, or indoor decoration devices, and is easy to handle and store. The purpose is to provide an excellent decorative device. For this purpose, the present invention allows a flexible lead wire to be led out from one end side of the rod-shaped main body case, connects a light emitting body to the tip of the lead wire, and connects the light emitting body to a lighting control device housed in the main body case. The light is driven by a circuit section or a power supply section. With this configuration, the decoration device is made into a compact unit body mainly consisting of a rod-shaped main body case, and can be applied to various purposes as a decoration device for various objects such as various ornaments, display devices, or indoor objects. Furthermore, it is designed to be easier to handle and store. In addition, by forming the other end of the body case on the opposite side from the lead wire into a particularly tapered shape, the body case can be inserted together with decorative flowers, etc. into a flower oasis where decorative flowers, etc., are inserted. By doing so, the decorativeness of the flower arrangement can be further enhanced.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a decorative unit according to the present invention, and the decorative unit 1 mainly includes a rod-shaped main body case 2 made by blow molding using vinyl chloride or injection molding from ABS resin or the like. This main case 2 has an upper case 2a and a lower case 2b screwed together at an intermediate position slightly upward in the axial direction.
It is connected by a connecting means 2c such as a bayonet, and a lighting control circuit section 6 consisting of an electric element 5 arranged on a printed circuit board 4 is fixedly housed inside, and a dry cell battery is installed in the lower case 2b. Power supply units 3, 3 consisting of are arranged to be replaceable. A rechargeable battery may be used as the power source.

Reference numeral 10 denotes a plurality of bendable flexible lead wires led out from one end of the main body case 2, and at the tip thereof a light emitting body D consisting of an LED or a miniature bulb, etc., and a condenser microphone or a piezoelectric ceramic transducer are connected. An acoustic sensor 7 consisting of the following is connected.
In this embodiment, there are three light emitters D, each of which emits a different color. Further, the acoustic sensor 7 drives the light emitter D in response to the output signal when it collects sound, as will be described later. Numeral 8 is a gasket for fixing the lead wire 10 made of a ring-shaped rubber material or a silicone caulking material, and is provided with an armoring effect and a waterproofing effect on the lead wire 10. Reference numeral 11 denotes a switch part, which may be a normal unitized switch, but the length A from the connection start point to the connection completion point of the connection means 2c is longer than the free length B of one of the conductive elastic electrodes 25. By doing so, when the connecting means 2c is loosened halfway,
It is also possible to use a type of switch that is disconnected away from the other conducting electrode. When the switch section 11 is operated, the lighting control circuit section 6 is driven, and the light emitting body D
lights up. The other end 27 of the main body case 2 on the opposite side from the lead wire 10 has a tapered shape for easy insertion into the oasis, as will be described later, and can also be hung by passing it through a hanging string or the like. A hole 9 is formed as a locking part so that it can be used by locking it to a hanging tool or the like.

FIG. 3 shows an example of the use of the decorative unit 1, in which 20 is a flower arrangement to be decorated on a table at a banquet, and an oasis 21 made of sponge etc.
The decorative unit 1 is inserted together with a decorative flower 22 in the holder. The number of inserts for decoration unit 1 is 2 Morihana.
It can be freely increased or decreased depending on the size of 0.

FIG. 4 shows the lighting control circuit.
1 is a power supply stabilizing capacitor, R1 and R2 are reference voltage setting resistors, and 7 is the above-mentioned acoustic sensor.
12 is an operational amplifier, which has input terminals X1 to X4.
and output terminals Y1 to Y4, and the reference voltage set by the resistors R1 and R2 and the output signal of the microphone 7 are input to input terminals X2 and X3. Q is a transistor whose base side is connected to the output terminal Y3, and the light emitting body D is connected in parallel. C2 is a capacitor provided on the base side of the transistor Q, and even after the output terminal Y3 is turned off, its discharge current makes the transistor Q conductive for a while, giving a soft impression to the lighting.

In the above configuration, when sounds such as applause occurring in the banquet hall are collected by the acoustic sensor 7,
The magnitude of the output signal and reference voltage is determined by the operational amplifier 12.
When the output signal is larger than the reference voltage, the base current of the transistor Q flows through the output terminal Y3, the transistor Q becomes conductive, and the light emitter D emits light. In other words, when the venue gets excited with loud applause, the light-emitting device D
is lit to illuminate the flower arrangement 20.

FIG. 5 shows another embodiment of the lighting control circuit, in which 15 is an astable multivibrator consisting of capacitors C, C, transistors Q, Q, resistors R, R, etc. The above luminous body D
are connected, and the left and right light emitters D blink alternately. As described above, various lighting control circuits for the light emitter can be considered, and for example, the light intensity of the light emitter may be changed. Of course, this decorative unit 1 can be widely used not only as a flower arrangement 20 but also as various ornaments, display devices, and interior decorations.

(Effect of the invention) As explained above, the decorative unit 1 according to the invention houses the lighting control circuit section 6 and its power supply sections 3, 3 inside the rod-shaped main body case 2, and is connected to the lighting control circuit 6. A bendable lead wire 10 is led out from one end of the main body case 2, and a light emitter D is connected to the tip of the lead wire 10.
Since the other end portion 27 of the main body case 2 is formed into a tapered shape, the light emitting body D, its lighting control circuit portion 6, power source portions 3, 3, etc. can be integrated into a unit, and it is easy to handle and store. It can be used for a variety of purposes, such as Morika 20, various ornaments, display devices, or indoor decorations.
In particular, by making the other end 27 of the main body case 2 tapered, a desired number of them can be inserted into the oasis 21 of the flower arrangement 20 and used. In this case, the number of parts in the built-in lighting control circuit 6 varies from unit to unit, so even if the switch is turned on in the same way, the lighting cycle will vary depending on each unit, making the decorative effect even better. can be taken as a thing.
