Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a decorative light bulb that is installed in a lantern or a lantern and can produce a suitable light source with a soft mood by using dispersed light from multiple small light sources.

[0002]

[Prior art]

 Many of the current lanterns and paper lanterns use a light bulb that imitates a candle flame on a candlestick as a light source instead of a candle.

[0003]

[Problems to be solved by the device]

 In the conventional technology described above, the surroundings are bright because the flame-shaped light bulb of a candle shines strongly with only one, but the light source part is extremely bright, but the peripheral part, especially the lower part, is dark and illuminates. The first problem is that the patterns that are displayed are partial.

Moreover, although it becomes brighter as a whole by increasing the light intensity, it not only destroys the traditional Japanese image of lanterns and lanterns, but also increases the heat generated by the light bulb, which is also dangerous. There is a problem.

In order to eliminate the above-mentioned problems, the present invention enables distributed lighting of a large number of small light bulbs to provide a light with a soft mood, and the small light bulbs described above can be used even in commercial AC. The purpose is to enable continuous lighting without difficulty, and to disperse a large number of small light bulbs to improve heat dissipation and to suppress heat generation per unit.

[0006]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to connect a plurality of small bulbs 1 and 1 in series with a rigid insulation-coated wire 2 in series, and a plurality of pairs of bulb series 3 that are connected at the free end of the insulation-coated wires 2 and 2 in parallel. This can be achieved by bundling the insulation-coated electric wires 2,2 to the electrodes 4a, 4a of the bulb base 4 at the connecting portions 2a, 2a and connecting them in parallel.

The lengths of the series 3 of light bulbs may be sequentially different from each other, and the lengths of the insulated covered wires 2, 2 may be random.

[0008]

[Action]

 By connecting, for example, four small light bulbs having a rated voltage of, for example, 28 V and 3 W, in series, it is possible to obtain a light bulb series set having a total working voltage of 112 V.

Then, after connecting the plurality of sets in parallel to the bulb base, a commercial AC 100 volt R.O. M. By energizing S, a voltage of about 25 V can be applied to each light bulb, and each light bulb can sustainably light up with a small amount of heat at a voltage of 89% of the above rated voltage.

Since this lighting state is scattered light by a large number of small light bulbs, it is good for heat dissipation, and it is possible to illuminate in a soft mood. It is suitable as a pseudo candle in a paper lantern.

【Example】

 Examples will be described with reference to the drawings. The basic structure of the present invention is as follows. First, for example, four well-known small electric power compact bulbs 1 such as bead balls are used as insulating wires 2 and 2 of equal length or different length having rigidity like a single wire vinyl covered electric wire. As shown in Fig.2, after bending back in the middle to connect in series, remove the coating on the two free ends of the wires 2 and 2 to expose the core wire and make parallel connection parts 2a and 2a, and then connect the small bulbs 1 and 1. By bringing them close to each other, it is possible to make a self-supporting series 3 of electric bulbs as shown in FIG.

Then, a plurality of the light bulb series sets 3 are arranged as shown in FIG. 4 and are connected in parallel by the parallel connection parts 2a and 2a so that the light bulb series sets 3 and 3 are parallel to each other, and then the tapes are attached to the respective connection parts. Insulation treatment such as wrapping treatment is applied to bundle a large number of electric wires 2, 2 as shown in Fig. 5.

Next, while inserting the lower part of the bundled electric wires 2, 2 into a well-known light bulb base 4 as shown in FIG. 6, the parallel connection portions 2a, 2a of the electric wires 2, 2 are connected to each other as shown in FIG. After connecting to the two electrodes 4a, 4a of the bulb base 4 by means such as soldering or caulking, the lower part of each wire 2,2 and the inner surface of the bulb base 4 are adhered and solidified to obtain a large number as shown in FIG. We obtain the basic composition of the decorative light bulb of this invention by the group of small light bulbs.

By making the lengths of the insulated wires 2, 2 random, the small light bulbs 1, 1 can be dispersed in a wide range as shown in FIG. 1, and as shown in FIG. The lengths of the series pairs 3, 3 may be greatly different from each other.

The basic structure of the decorative light bulb of the present invention is as described above. Next, specific examples and usage examples thereof will be described in detail below.

By connecting four small light bulbs 1 and 1 each having a rated voltage of, for example, 28 V and 3 W and having a power of about 3 W as shown in FIG. 2, a total working voltage of 112 V, for example, a light bulb series as shown in FIG. You can get the set 3.

Then, the plural sets (FIG. 4) are bundled with the insulation-coated electric wires 2, 2 as shown in FIG. 5 and concentrated as described above and connected in parallel to the bulb base 4 as shown in FIG. Commercial AC 100V R.S. M. By energizing S with a socket as shown in FIG. 8, it is possible to apply a voltage of about 25 Volts per bulb, and at a voltage of 89% of the above rated voltage, it is impossible to heat each bulb 1,1 with a small amount of heat. Can be lit continuously without.

That is, as a specific example thereof, as shown in FIG. 8, by screwing or twist-locking the bulb cap 4 into a well-known light bulb socket 5, AC 100 V applied to the socket terminals 5a, 5a is applied to the electrodes 4a, 5a. By applying it to each small light bulb series set 3,3 via 4a, all of the small light bulbs 2,2 can be turned on.

Since this lighting state is dispersed light by a large number of small light bulbs, soft mood illumination is possible, and it is used as a lantern 10 wired with an AC cord 10a as shown in FIG. 9 or as a pseudo candle in a line lamp. If so, the heat generated from a large number of small light bulbs is small as described above, so it is safe.

[0020]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. A plurality of small bulbs 1,1 are connected in series with a rigid insulation-coated wire 2 in series. A plurality of pairs of bulb series 3 are connected at the free end of the insulation-coated wires 2,2 with a parallel connection part 2a, 2a. Since the insulated covered electric wires 2 and 2 are bundled and connected in parallel to the 4 electrodes 4a and 4a, it is possible to arbitrarily arrange a large number of small light bulbs 1 and 1, and the arrangement state does not change indefinitely. Distributed light from a large number of small light bulbs makes it possible to provide a light with a soft mood and good heat dissipation. Even in commercial AC, the voltage applied to each of the small light bulbs above is kept below the rated voltage to generate heat. This has the effect that it can be kept small and that many small light bulbs can be safely and safely lighted continuously.

According to the second and third aspects, since a large number of small light bulbs 2, 2 can be sparsely distributed at a larger interval, it is easier to radiate heat, and soft mood illumination and decorative light can be obtained. The effect that it can be added can be added.
