Abstract

Abstract Translated from Japanese (57)【要約】 【目的】ブリッジガラスに支持された一対の内部リード 線間で放電や短絡を生じるのが防止された白熱電球およ びこれを用いた照明装置を提供する。 【構成】一端が封止されたバルブ2にフィラメント8を 収容し、他端がフィラメント8に接続された一対の内部 リード線10,11の一端を封止部3に導き、この封止 部3とフィラメント8との間にブリッジガラス9を設 け、このブリッジガラス9の両端部に上記一対の内部リ ード線10,11を互いに離間して支持し、このブリッ ジガラス9の中間部にアンカー12を支持し、このアン カー12はフィラメント8の中間部を支持していること を特徴とする。 【作用】ブリッジガラスの中間部にアンカーが支持され るとともに、ブリッジガラスの両端部に一対の内部リー ド線が支持されるから、これら内部リード線が相互に離 間し、これら内部リード線間で放電や短絡が生じるのが 防止される。 (57) [Abstract] [PROBLEMS] To provide an incandescent light bulb in which electric discharge and a short circuit are prevented from occurring between a pair of internal lead wires supported by a bridge glass, and a lighting device using the same. [Construction] A filament 8 is housed in a bulb 2 whose one end is sealed, and one end of a pair of internal lead wires 10, 11 whose other end is connected to the filament 8 is guided to a sealing part 3 and the sealing part 3 A bridge glass 9 is provided between the bridge glass 9 and the filament 8, the pair of internal lead wires 10 and 11 are spaced apart from each other at both ends of the bridge glass 9, and an anchor 12 is supported at an intermediate portion of the bridge glass 9. However, this anchor 12 is characterized by supporting the intermediate portion of the filament 8. Since the anchor is supported on the middle portion of the bridge glass and the pair of inner lead wires is supported on both end portions of the bridge glass, the inner lead wires are separated from each other and a discharge occurs between the inner lead wires. And a short circuit is prevented.
