【発明の詳細な説明】 産業上の利用分野 本発明は、電子式複写機に好適な複写機用ハロゲン電球
に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a halogen lamp for a copying machine suitable for an electronic copying machine.
従来の技術 従来、タングステンフィラメントを配設した透光性管内

黒化を防止したハロゲン電球が知られている。2. Description of the Related Art Conventionally, halogens such as chlorine and bromine are enclosed together with an inert gas such as argon, krypton, and nitrogen in a light-transmissive tube having a tungsten filament, and the halogen and tungsten evaporated from the tungsten filament are sealed. There is known a halogen light bulb that causes a halogen cycle to occur and prevents blackening of the tube wall until the end of its life.
通常、ハロゲンは炭化水素化合物として管内に封入され
るが、例えばCHCl3は電球が点灯されると分解され、 2CHCl3→Ｃ＋HCl＋2Cl ……(1) となり、炭素の一部は管内に残存する水や酸素に対して
ゲッタとして働く。Normally, halogen is enclosed in the tube as a hydrocarbon compound. For example, CHCl 3 is decomposed when a light bulb is turned on and becomes 2CHCl 3 → C + HCl + 2Cl …… (1), and some carbon remains in the tube. It acts as a getter for oxygen.
Ｃ＋H2O→CO＋H2 ……(2) 炭素の他の一部はタングステンフィラメント表面に付
着、侵入して炭化タングステンを生成する。従って管内
に封入される炭素が多すぎると、フィラメントがもろく
なることがある。C + H 2 O → CO + H 2 …… (2) Other part of carbon adheres to and penetrates the surface of the tungsten filament to form tungsten carbide. Therefore, if too much carbon is enclosed in the tube, the filament may become brittle.
従来、例えば塩素の炭化水素化合物を使用したハロゲン
電球では管内に、炭素がフィラメント発光部の表面積に
対して1.2×10-6g原子/cm2〜２×10-6g原子/cm2の範囲
に封入したものが提案されている。Conventionally, for example, in a halogen bulb using a hydrocarbon compound of chlorine, carbon in the tube is in the range of 1.2 × 10 -6 g atom / cm 2 to 2 × 10 -6 g atom / cm 2 with respect to the surface area of the filament light emitting part. The one enclosed in is proposed.

化タングステンの量が多くなり、フィラメントはもろく
なりやすく、フィラメントの熱膨張・収縮の差が大きく
フィラメントの疲労が大きく、フィラメントの早期断線
に至りやすいという問題点があった。Problems to be Solved by the Invention However, in such a conventional configuration, for example, lighting for 2 seconds 1
When the blinking cycle of off for seconds is repeated continuously, the filament temperature does not drop so much at the time of extinguishing, so the amount of carbon adhering to and entering the tungsten filament and forming tungsten carbide is also small, and the difference in thermal expansion and contraction of the filament However, if the blinking cycle of repeating the blinking of 2 seconds on and 1 second off for 100 times and then extinguishing for 10 minutes is repeated, the filament will not be disconnected for 10 minutes. In addition, since the filament temperature drops to the ambient temperature of the light bulb, the amount of tungsten carbide produced increases, the filament is easily fragile, the difference in thermal expansion / contraction of the filament is large, and the fatigue of the filament is large, which may lead to early disconnection of the filament. There was a problem that it was easy to reach.
本発明はこのような問題点を解消するためになされたも
ので、短い点滅周期と長い消灯を繰り返しても短寿命に
至らず、長寿命の複写機用ハロゲン電球を提供するもの
である。The present invention has been made in order to solve such a problem, and provides a halogen light bulb for a copying machine, which does not have a short life even if a short blinking cycle and a long light-out are repeated, and has a long life.

A filament 4 having a light emitting portion 2 and a non-light emitting portion 3 is supported by a support 5 inside an elongated quartz glass tube 1. The filament 4 is grounded to the external lead wire 8 via the molybdenum foil 7 at the pinch seal portion 6, and the tip of the external lead wire 8 is connected to the base 9. Carbon in a glass tube having such a constitution is 0.15 × 10 −7 g atom, 0.3 × 10 −7 g atom, 3 × 10 −7 g atom, 6 × 10 6 per unit surface area (cm 2 ) of the filament light emitting part.

とができた。 As shown in the above table, carbon with a carbon content of 0.15 to 10 -7 g atom / cm 2 was blackened because the carbon content was too small to be effective as a getter. When the amount of carbon is 1.5 × 10 -6 g atom / cm 2 , the number of blinks was 150,000 times or more under the lighting condition of 2 seconds on and 1 second off, but after repeating 2 seconds on and 1 second off 100 times Under the lighting condition of 10-minute light-off, the wire was broken within the 10-minute light-off time and did not reach 150,000 times or more. After all, long-life bulbs have 0.3 carbon
