Prior Art 1 and 2
Are trying to use a glass bulb for general lighting as it is, it is difficult to insert a plurality of small bulbs in a required arrangement in the glass bulb.

There is also a problem in vibration resistance.

That is, in the prior art 1, since the neck portion of the glass bulb is narrow, it is difficult to arrange the electric lamp 104 linearly or annularly in the glass bulb.

In the prior art 2, since the neck portion of the glass bulb is still narrow, a table 202 having a desired size cannot be used, and the wheat ball 203 is supported by only one conductive wire of the wheat ball 203. The support of the wheat ball 203 becomes unstable.

Furthermore, in the prior arts 1 and 2, since the glass bulb is heated and sealed when the glass bulb is sealed, a special sealing facility is required, and a component having insufficient heat resistance inside the glass bulb is required. Can not be enclosed.

On the other hand, the prior art 3 uses a synthetic resin as a material for the glove, so that sealing by heating is unnecessary, but vibration resistance is poor because the small light bulb accommodated inside is only supported by its conductor. When a plurality of light bulbs are connected in series as a small light bulb, they cannot be stored in a predetermined position.

The present invention provides a light bulb device which can provide a required earthquake resistance and is easy to assemble when a plurality of small base lamps are connected in series and stored in a glove. This is the purpose of 1.

A second object of the present invention is to make it possible to provide various light bulb devices by sharing parts.

Further, a third object of the present invention is to provide a bulb device having a long life.

[0029]

According to a first aspect of the present invention, there is provided a globe having an opening at one end and a light-transmitting portion, a glove connection opening having a wide opening relative to one end, and a globe connecting to the other end. An enclosure including a base body having a narrow-mouthed power connection opening and a base connected to the glove connection opening at the open end of the glove; a plate portion fitted into the glove connection opening of the base, and a bulb mounted An attachment having a base and a support standing part, fixed to the base; a plurality of small base lamps assembled together, mounted on the bulb mounting part of the attachment, and conductors at both ends penetrating the attachment for power connection It is characterized in that it comprises: a series of lampless small bulb series connected to the opening side; and a support that stands from the support standing part of the attachment and supports the series of lampless small bulbs. It is set to.

In the present invention and the following inventions, the definitions and technical meanings of terms are as follows unless otherwise specified.

First, the envelope will be described.

The envelope accommodates the small-capacity small light bulb inside and protects the small-capacity small light bulb electrically and mechanically.

The envelope includes a glove and a base, and can be used for optically processing light emitted from a small-capacity miniature bulb as required. For example, by forming the envelope from a transparent colored synthetic resin, it is possible to obtain a color light bulb having a larger amount of light than in the past. In addition, a light diffusing material is used, a light diffusing film is formed on one or both of the outer surface and the inner surface of the envelope, or the surface is roughened to form a light diffusing light bulb device. You can also. Light diffusion can also be imparted by forming a prism-shaped portion on the inner surface or outer surface of the envelope made of a transparent material.

Further, the material of the envelope is such that the glove has a glass, a synthetic resin such as a polycarbonate resin, and other insulating properties, has a certain mechanical strength, and has at least a part of a transparent material for guiding light. Any type may be used as long as there is an optical unit. The base is preferably a synthetic resin, for example, a BMC (bulk molding compound) material obtained by mixing an inorganic filler with a polyester resin, a polyethylene terephthalate resin, a polyamide resin, or the like. However, it does not prevent it from being made of glass or other materials if necessary.

The preferred configuration of the envelope is a glove made of glass having excellent translucency and a base made of synthetic resin having excellent workability. However, when the glove is formed of a synthetic resin, an acrylic resin, a polycarbonate resin, or the like having excellent translucency can be used.

The glove having translucency means that a part of the globe may be translucent in addition to the entire globe being translucent. For example, it is possible to provide a semi-indirect illumination by covering a hemispherical portion at the top of the glove with a reflective film formed by aluminum evaporation.

The substrate may be translucent, but may be non-translucent if desired.

For connection between the glove and the base, various known means such as an adhesive, welding, and mechanical engagement can be used. However, when the charged part such as the conductor of the series of small-capacity miniature bulbs is exposed when the glove is removed, it is preferable that the glove is not removable from the base.

The power connection opening of the base can be fitted with a base having the same specifications as a general lighting bulb. Then, by connecting both ends of the series of lampless small bulb series to the base in a conventional manner, the bulb apparatus of the present invention can be mounted on the bulb socket and used like a general lighting bulb.

Further, the lighting device can be constructed by directly connecting the power connection opening to the lighting device main body such as a spike or a pole without mounting the base in the power connection opening. In this case, both ends of the series of small lampless light bulbs can be directly connected to a power source.

In order to provide a bulb that can be replaced with a general lighting bulb, the envelope is desirably a PS-shaped or G-shaped bulb having the same shape as the general lighting bulb.
It may be T-shaped instead of shape. However, since the present invention is not intended only to replace the light bulb for general lighting, the shape of the envelope may be any. For example, C (light), G (small circle), chandelier, A, FE, GR, PAR, PS, R, R
It may be a P, PK, S shape, or any other irregular shape, for example, a polyhedral shape, a hieroglyphic shape such as a fruit-like shape, or an abstract shape.

Next, the attachment will be described.

The attachment is one of the features of the present invention, and supports the small base bulb and plays an important role for electrical connection to a power source. The plate portion of the attachment fits inside the wide-open glove connection opening of the base. Preferably, the closed space is formed in cooperation with the glove.

Further, the attachment is fixed to the base by a fixing tool such as a screw or an adhesive.

Further, the bulb mounting portion of the attachment is
The small-capacity small light bulb is supported, and a pair of conductors at both ends of the series of small-capacity small light bulbs are led out to a power supply connection opening.

Further, the support upright portion of the attachment is a portion where the support separately from or integral with the attachment stands up. That is, the support rises from the attachment.

Next, a series of the small-capacity miniature bulb series will be described.

The term “baseless lamp” of the small-capacity small bulb basically refers to a light bulb that does not use a base made of metal or synthetic resin. Structure, a bead sealing structure sealed with bead glass, a structure in which the end of a glass bulb is heated and melted with a burner and sealed. For the processing of the external lead wire, a wedge base structure in which the external lead wire is attached along the pinch sealing portion, and a structure in which the external lead wire projects from the sealing portion in a linear or loop shape in the valve axis direction. And so on.

The small size of the small-capacity light bulb is a bulb having a small size and a small volume, such as a wedge-based light bulb and a subminiature light bulb, and being about one third or less of the commercial power supply voltage. A light bulb that is lit under a nominal voltage rating. Regarding the shape of the valve, various shapes are allowed, but it is preferably an elongated shape like a T-shaped valve. It is preferable that the external lead wire is led out from both ends with a sealed structure at both ends, but a single sealed structure is also acceptable.

The term “light bulb” of the small-capacity miniature bulb refers to an incandescent light bulb having a filament sealed inside the bulb. Inert gas is sealed inside the bulb, but especially when krypton or xenon gas is sealed, these gases have a large atomic weight, low thermal conductivity, and can reduce heat loss inside the bulb. Desired results are obtained for miniaturization of the bulb and prolonging its life or improving its efficiency. Further, the higher the pressure of the filling gas, the stronger the above tendency. Of course, it is needless to say that a valve structure that can withstand a high gas pressure at a high temperature at the time of lighting is required.

Furthermore, since the small-capacity miniature bulb is lit at a low voltage, the filament is thicker and shorter than that of a general lighting bulb, so that it has a longer life and is more resistant to vibration.

The term “collection” refers to arranging a plurality of small base lamps at a small interval from each other so as to have a compact outline. It is preferable that the small gold bulbs are arranged at small intervals. The small interval is a distance of approximately 1.5 times or less, preferably 1 time or less of the length of the bulb of the small-capacity small light bulb,
The small base lamps may be in contact with each other.

However, since the heat-generating portions are dispersed by being separated from each other at an appropriate distance, the temperature rise can be reduced.

A preferable means for compactly assembling the small base lamps is to arrange the bulb axes parallel to each other, and to arrange the bulb axes concentrically, more preferably at equal intervals. Further, in order to store the light bulb in the envelope, the axis of the envelope and the axis of the small-capacity small light bulb are made to coincide with each other, so that a compact and compact appearance light bulb can be obtained. However, some small lamps can be shifted axially with respect to the remaining small lamps, in which case the length of the envelope in the axial direction is slightly longer. The effective light quantity can be increased by reducing the kick of light by comrades.

In order to connect the small lamps in series with each other in series, the external lead wires of the lamps may be connected directly or via an appropriate connecting member such as another conductor.

By setting the sum of the nominal rated voltages of the small lamps to be slightly higher than the nominal power supply voltage, the luminous efficiency is slightly lowered but the difference is hardly noticeable.
A bulb with a longer life can be obtained. To set the sum of the nominal rated voltages of the small lamps to be slightly higher than the nominal power supply voltage is, for example, generally 100% to 120%.
Hereinafter, it can be preferably in the range of 110% ± 5%.

Next, the support will be described.

The support is for supporting the series-connected small-capacity light bulb series connection body at a predetermined position, and stands upright from the attachment. Since the baseless small bulbs each have a bulb, unlike a conventional general lighting bulb, which only supports a filament, its weight cannot be ignored, so the support has a certain level of mechanical strength. Must be something.

The method for supporting the series of lampless series lamps may be of any construction, for example, it may support a bulb, a conductor for connecting between bulbs or a series of series of lampless miniature bulbs. May be supported. The conductor connected to the light bulb can be made to have mechanical strength, and can also function as a support.

When supporting the conductor forming the intermediate connection between the light bulbs, it is preferable that at least the portion directly supporting the intermediate connection is made of an insulator. Then, two or more intermediate connecting portions can be supported at the same time. The insulating support portion can be made of a synthetic resin such as polyamide, glass, or the like.

Further, if a metal rod is used in a portion rising from the attachment in order to provide sufficient rigidity, preferable results can be obtained. However, if necessary, it can be formed integrally with the attachment.

Finally, the operation of the present invention will be described.

The light bulb device of the present invention comprises a series of small-capacity small-bulb series light bulbs in which a plurality of small-capacity small bulbs are connected in series.
