Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、白熱電球に関する。[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION The present invention relates to an incandescent light bulb.
従来の白熱電球の一例を第４図に示す。第４図において
、１はフィラメントであって、リード２．３間に取り付

ント１に通電する構造となっている。An example of a conventional incandescent light bulb is shown in FIG. In FIG. 4, 1 is a filament, which is attached between the leads 2 and 3 and enclosed in the bulb 4. Lead 2, 3
is formed of a conductive material, supports the filament 1, and is connected to an external power source through a cap (not shown) to supply electricity to the filament 1.
上述した従来の白熱電球は、フィラメントが１ケで構成
されているため、予告もなくフィラメントが切れるとい
う欠点がある。そのため、突然の暗闇に対応できず、代
替えの電球さえもさがせないという場合がある。The above-mentioned conventional incandescent light bulb has a single filament, and therefore has the disadvantage that the filament can break without prior notice. As a result, they may not be able to cope with sudden darkness or find replacement light bulbs.
本発明の目的は、フィラメントが切れても、突然暗闇に
なることがなく、電球の交換がスムーズにできる白熱電
球を提供することである。An object of the present invention is to provide an incandescent light bulb that does not suddenly become dark even if the filament breaks, and allows for smooth bulb replacement.
本発明の白熱電球は、互いに並列に接続された複数のフ
ィラメントを有している。The incandescent light bulb of the present invention has a plurality of filaments connected in parallel to each other.
次に本発明について、図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は、本発明の一実施例の概念を示す側面図である
。第１図において、１ａは第１のフィラメント、ｌｂは
第２のフィラメントで、リード２．３間に互いに並列に

ラメントが発光する。例えば、第１のフィラメン）ｌａ
が使用寿命により切れた場合、その際すぐ（第２のフィ
ラメント１６が切れるまで）に電球交換を行えば、暗闇
での作業がなくなる。FIG. 1 is a side view showing the concept of an embodiment of the present invention. In FIG. 1, 1a is a first filament and lb is a second filament, which are attached in parallel between the leads 2.3. When the power is turned on, both filaments emit light. For example, the first filament) la
When the bulb burns out due to its service life, if the bulb is replaced immediately (until the second filament 16 burns out), there is no need to work in the dark.
尚、片方のフィラメントが切れたことは、光度の差によ

気的に検出することもできる。The breakage of one of the filaments can be determined by the difference in luminous intensity, and can also be detected electrically by monitoring the current.
第２図、及び第３図は、本発明の第２及び第３の実施例
についてのバルブ内のリード及びフィラメントの構成図
である。FIGS. 2 and 3 are configuration diagrams of reeds and filaments in bulbs for second and third embodiments of the present invention.
第２図、第３図共にリード１２，１３，２２゜２３を途
中で分岐することにより、先端を複数化し、そのリード
１２，１３，２２．２３の先端に２ケ（第２図）、もし

を並列に接続している。In both Figures 2 and 3, the leads 12, 13, 22 and 23 are branched in the middle to have multiple tips, and the tips of the leads 12, 13, 22, and 23 have two wires (Figure 2) or , 3 filaments (Fig. 3) la, lb, lc
are connected in parallel.
このように構成することにより、リードの長さに関係す

。第１の実施例と同様にどれかが断線しても残りのフィ
ラメントで発光が続けられるため、暗闇での作業がなく

更に安定であり、１本断線してもあわてることなく、相
当期間サービスが続けられる。例えば、車のヘッドライ
トなどに使用した場合、予備の役にも立つ。With this configuration, a large number of filaments can be connected in parallel regardless of the length of the leads. As in the first embodiment, even if one of the filaments breaks, the remaining filaments continue to emit light, eliminating the need to work in the dark. Furthermore, in the case of the third embodiment, it is more stable than the first embodiment, and even if one wire is broken, the service can be continued for a considerable period of time without panic. For example, when used for car headlights, it can also be useful as a backup.
以上説明したように本発明は、互いに並列に接続された
複数のフィラメントを備えることにより、電球が一瞬で
切れることをさけ、電球の交換が容易にできるという効
果がある。As explained above, the present invention has the advantage that by providing a plurality of filaments connected in parallel to each other, the light bulb can be prevented from burning out instantly and the light bulb can be replaced easily.
