552611 A7 B7_ 五、發明説明（1 ) 〔發明所屬之技術領域〕 (請先閲讀背面之注意事項再填寫本頁) 本發明，是關於能防止由於堆積在電子管心柱的電子 放射物質等之導電性物質造成在燈使用期限末期時持續異 常放電的螢光燈。 〔先前技術〕 通常，將具備有熱陰極之螢光燈經長期以高頻點燈時 ，構成燈絲的鎢（W )等之物質、或在此塗敷的氧化鋇等 電子放射物質、及接近燈絲之構成內部導線的鎳（N i ) 等之導入線前端構件將會飛散，這些飛散物將附著在真空 管壁而產生黑化，並且該飛散物有時也會附著堆積在接近 燈絲的擴口電子管心柱之前端面。特別是，在燈的使用期 限末期時，有時在燈絲之電子放射物質飛散後，燈會引起 半波放電。如此的異常放電發生時，燈絲物質或內部導線 的物質之飛散將變成很激烈，而容易附著在接近燈絲的擴 口電子管心柱之前端面。 經濟部智慧財產局員工消費合作社印製 附著物由於是導電體，堆積某程度的話可能會形成通 電路徑。也就是說，電極飛散物質等堆積在擴口電子管心 柱的前端面的話，該飛散物質分別接觸到互相分開被附著 的一對內部導線（導入線），而在一對內部導線間形成上 述由飛散物質所造成的導電路徑。因此，一對內部導線會 藉由被形成在擴口電子管心柱的前端面的上述電子放射物 質之堆積物的導電路徑而被互相導通。 通常，在使用期限末期燈絲斷線時，螢光燈之點燈裝 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -4 - 552611 A7 —___B7 _____ 五、發明説明（2 ) {請先閲讀背面之注意事項再填寫本頁} 置會停止振盪，可是如上述地由飛散物質的堆積物之導電 路徑使一對內部導線間導通（短路）時，即使燈絲已斷線 ’點燈裝置也可能會持續動作。例如，螢光燈的點燈裝置 ’是燈絲之預熱電路對螢光燈將預熱電容器並聯連接的所 謂電容器預熱方式之變頻器時，燈絲斷線時因預熱電容器 將被從點燈電路切斷，所以會停止振盪。可是，在一對內 部導線間由於電子放射物質的堆積物被形成有導電路徑時 ’即使燈絲已斷線可是導電路徑還會通電，成爲維持著預 熱電容器連接在點燈電路之狀態，點燈裝置會持續振盪。 此時，螢光燈因斷線的一方之燈絲將不會作爲熱陰極作用 ’而將重覆所謂半波放電，而持續由異常放電所進行之點 燈動作。並且，具有由該異常放電而使導電路徑發熱，讓 擴口電子管心柱發生熱破損、或在導電路徑通過大的電流 ’產生很大的電力損失的缺點。 經濟部智慧財產苟員工消費合作社印製 而且，通常，電子放射物質從燈絲完全飛散而枯竭時 ，雖然燈會不亮，可是在變頻器點燈的情況，因二次電壓 很高所以在電子放射物質完全飛散而枯竭後，有時也會持 續半波放電’如此時也將在上述一對內部導線間所形成的 堆積物之導電路徑通電，使該導電路徑發熱，會讓擴口電 子管心柱破損，或流通過大的電流而產生大的電力損失。 因此，已往提出有設法防止由如此的電子放射物質造 成一對內部導線間的短路之技術。作爲其一例有例如在日 本特開平1 1 一 1 2 0 9 6 0號公報所記載的營光燈（以 下，稱爲「習知技術1」）或在日本特開平 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 552611 A7 B7 五、發明説明（3) (請先閱讀背面之注意事項再填寫本頁) 2 0 0 〇 - 3 1 1 6 5 4號公報所記載之螢光燈（以下’ 稱爲「習知技術2」）。這些習知技術1 ，2，是只在一 對導線間的擴口電子管心柱上設置突起，使一對導線間的 導電路徑變長，設法防止一對導線間之短路。 【發明內容】 〔發明欲解決之課題〕 然而，在如此的習知技術1 ，2，具有一對之導線間 的防止短路效果不一定很高之課題。 也就是說，通常螢光燈內的封入氣體壓力爲數百P a ，在此壓力狀態，在燈使用期限末期之前，飛散的燈絲物 質或導線之電子放射物質，將不會從燈絲只成放射狀地蒸 發，而將成爲一種亂流狀態飛散•蒸發，其中一部份會對 上述電子管心柱上之突起，電子放射物質將繞入附著在電 子管心柱上而堆積。因此，該電子放射物質容易在一對導 線間的電子管心柱上被連續地形成而形成導電路徑。特別 是，在變頻器點燈時因2次電壓很高，具有在一對導線間 容易發生短路之課題。 經濟部智慧財產^員工消費合作社印製 本發明是考慮如此的情況，其目的，是要提供能夠阻 止電子放射物質連續地附著堆積到一對導入線（導線）間 之電子管心柱上，來抑制一對導入線間的短路等伴隨之持 續異常放電之螢光燈。 〔用以解決課題之手段〕 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公嫠） . 552611 A7 _ B7 五、發明説明（4 ) 關於第1發明，其特徵爲：是具備有：透光性放電容 (請先閲讀背面之注意事項再填寫本頁) 器；和被形成在透光性放電容器的內面側之螢光體層；和 被封入在透光性放電容器內之放電媒體；和被配設成讓透 光性放電容器的內部發生放電之一對燈絲電極；和支持該 電極的兩端部之一對導入線；和支持一對導入線的電子管 心柱；及分別被固定在前述一對導入線，從其中一方之導 入線向另一方的導入線側突出並且使之互相不接觸而重疊 的一對玻璃構件。 第2發明，其特徵爲：是具備有：透光性放電容器； 和被形成在透光性放電容器的內面側之螢光體層；和被封 入在透光性放電容器內的放電媒體；和被配設成在透光性 放電容器之內部發生放電的一對燈絲電極；和支持該電極 之兩端部的一對導入線；和支持一對導入線之電子管心柱 ;及分別被固定在前述一對導入線，朝向與前述燈絲電極 的長軸方向略平行之方向突出，突出的自由前端部互相在 導入線之長軸方向形成所希望的空隙之一對玻璃構件。 經濟部智慧財產局員工消費合作社印製 藉由第1或2之發明時，因分別被固定在一對導入線 的一對玻璃構件，是以從燈絲電極被遮蔽的方式覆蓋電子 管心柱上之其中一部份，所以從燈絲電極飛散的電子放射 物質會分別附著在該一對玻璃構件上堆積，在各玻璃構件 上將分別被形成導電物質層。 然而，這一對玻璃構件是以互相不接觸而重疊地分別 被固定在一對導入線，並且，其兩自由前端部是互相在導 入線的軸方向隔著所希望之空隙互相重疊，所以一對玻璃 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 552611 A7 B7 五、發明説明（5 ) 構件上的兩導電物質層，是電路性地被分斷。 (請先閲讀背面之注意事項再填寫本頁) 特別是，由於使第2發明中的空隙，在燈絲電極之長 方向（電極軸）略平行地延伸，將有效地被防止電子放射 物質繞入此空隙內附著而堆積。 藉由第1或2發明時，因能阻止如連結一對導入線間 形成放射物質的導電路徑，所以可以防止此等一對之導入 線間的短路，而能夠確實停止由於燈絲斷線造成點燈裝置 的振盪。 並且，由於是使一對導入線在電子管心柱上的至少根 基和其周圍部，由一對玻璃構件從電極覆蓋，所以即使來 自於電極的電子放射物質分別旋繞於一對玻璃構件之寬度 或直徑方向，飛散附著在電子管心柱上堆積而形成導電路 徑，也能防止電子放射物質附著在一對導入線的電子管心 柱上之基部及其周圍部而堆積。因此，即使螢光燈被連接 在如變頻器的方式的2次電壓很高的點燈裝置時，也能抑 制半波放電等異常放電之持續。 經濟部智慧財產局員工消費合作社印製 第3發明，是針對第1或2發明之螢光燈，其中，從 上述其中一方的導入線朝向另一方之導入線突出的其中一 方之玻璃構件的突出長度爲L 1 ，從另一方之導入線朝向 其中一方的導入線突出之另一方的玻璃構件之突出長度爲 L 2，當一列的導入線間之距離爲D時，滿足L 1 + L 2 > D的式子。 藉由本發明，由於在一對導入線所分別被固定的一對 玻璃構件之突出長度L 1 ，L 2、和一對導入線間的距離 本纸張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -8 -

Description of the invention (1) [Technical field to which the invention belongs] (Please read the precautions on the back before filling out this page) The present invention relates to the prevention of electrical conduction due to electron radiation substances and the like accumulated on the tube stem Sexual substances cause fluorescent lamps that continue to abnormally discharge at the end of the lamp's life. [Prior art] Generally, when a fluorescent lamp provided with a hot cathode is lit at a high frequency for a long period of time, a substance such as tungsten (W) constituting the filament, or an electron emitting substance such as barium oxide coated thereon, and the like The front end member of the lead wire such as nickel (N i), which constitutes the inner wire of the filament, will be scattered. These scattered substances will adhere to the wall of the vacuum tube to cause blackening, and the scattered substances may also accumulate and accumulate on the flaring near the filament The front face of the tube stem. In particular, at the end of the lamp's useful life, the lamp may cause a half-wave discharge after the electron emitting material of the filament is scattered. When such an abnormal discharge occurs, the scattering of the filament material or the material of the inner wire will become fierce, and it will easily adhere to the front end face of the flared electron tube stem close to the filament. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Since the attachment is a conductor, if it accumulates to a certain extent, a power path may be formed. In other words, if electrode scattering materials and the like are accumulated on the front end surface of the flared electron tube stem, the scattering materials respectively contact a pair of internal wires (lead-in wires) attached to each other, and the above-mentioned formation is formed between the pair of internal wires Conductive paths caused by flying materials. Therefore, a pair of internal wires are conducted to each other via the conductive path of the deposit of the above-mentioned electron emitting substance formed on the front end surface of the flared electron tube stem. Generally, when the filament is disconnected at the end of the service life, the paper size of the fluorescent lamp is applicable to the Chinese national standard (CNS) A4 specification (210X297 mm) -4-552611 A7 —___ B7 _____ V. Description of the invention (2) {Please read the precautions on the back before filling in this page} The setting will stop the oscillation, but when the conductive path of the accumulation of scattered matter makes the pair of internal wires conduct (short circuit) as described above, even if the filament is disconnected ' The light unit may also continue to operate. For example, the fluorescent lamp lighting device 'is a preheating circuit for filaments, which is a so-called capacitor preheating type inverter in which a preheating capacitor is connected in parallel to a fluorescent lamp. When the filament is disconnected, the preheating capacitor will be lit from The circuit is cut off, so it will stop oscillating. However, when a conductive path is formed due to the accumulation of electron emitting substances between a pair of internal wires, the conductive path will be energized even if the filament is disconnected, and the preheating capacitor is connected to the lighting circuit, and the light is turned on. The device will continue to oscillate. At this time, the broken filament of the fluorescent lamp will not act as a hot cathode, so it will repeat the so-called half-wave discharge, and continue the lighting operation by abnormal discharge. In addition, there are disadvantages that the conductive path generates heat due to the abnormal discharge, the flared tube stem is thermally damaged, or a large current is passed through the conductive path, resulting in a large power loss. Printed by the Intellectual Property of the Ministry of Economic Affairs and the Consumers' Cooperative, and usually, when the electronic radioactive material is completely scattered from the filament and dried up, although the lamp will not turn on, but when the inverter is turned on, the secondary voltage is very high. After completely scattered and depleted, half-wave discharge may also continue. In this case, the conductive path of the deposit formed between the above pair of internal wires is also energized, causing the conductive path to generate heat, and the flared tube stem may be damaged. , Or a large current loss caused by a large current. Therefore, a technique has been proposed to prevent a short circuit between a pair of internal wires caused by such an electron emitting substance. As an example, there is a camping lamp (hereinafter referred to as "knowledge technology 1") described in Japanese Unexamined Patent Publication No. 1 1 1 2 0 960, or the Chinese national standard is applied to Japanese Unexamined Patent Publication No. 1 (CNS) A4 specification (210X297 mm) 552611 A7 B7 V. Description of the invention (3) (Please read the notes on the back before filling out this page) 2 0 0 〇- 3 1 1 6 5 Light lamp (hereinafter 'referred to as "Knowledge 2"). These conventional techniques 1 and 2 are provided with protrusions only on a flared electron tube stem between a pair of wires to make the conductive path between a pair of wires longer and try to prevent a short circuit between a pair of wires. [Summary of the Invention] [Problems to be Solved by the Invention] However, in such a conventional technique 1, 2, there is a problem that the short-circuit prevention effect between a pair of wires is not necessarily high. In other words, the pressure of the enclosed gas in a fluorescent lamp is usually hundreds of Pa. In this pressure state, before the end of the lamp's service life, the scattered filament material or the electron emitting material of the wire will not be emitted from the filament. It will evaporate like a turbulent flow and evaporate, and a part of it will protrude on the stem of the above-mentioned electron tube, and the electron emitting material will wrap around and accumulate on the stem of the tube. Therefore, the electron emitting material is easily formed continuously on the tube stem between the pair of wires to form a conductive path. In particular, since the secondary voltage is high when the inverter is turned on, there is a problem that a short circuit easily occurs between a pair of wires. Printed by the Intellectual Property of the Ministry of Economic Affairs ^ Employee Consumer Cooperatives The present invention is considered to be such a situation, the purpose of which is to provide an electronic tube stem that can prevent the continuous attachment and accumulation of electron radioactive substances on a pair of lead wires (conductors) to suppress Fluorescent lamp with continuous abnormal discharge accompanied by short circuit between a pair of lead wires. 〔Means to solve the problem〕 This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 cm). 552611 A7 _ B7 V. Description of the invention (4) The first invention is characterized by: a light-transmitting capacitor (please read the precautions on the back before filling this page); and it is formed in light-transmitting A phosphor layer on the inner surface side of the discharge vessel; and a discharge medium enclosed in the light-transmitting discharge vessel; and a pair of filament electrodes arranged to discharge inside the light-transmitting discharge vessel; and supporting the One pair of lead wires at both ends of the electrode; and a tube stem supporting a pair of lead wires; and each of which is fixed to the aforementioned pair of lead wires, protrudes from one lead wire to the other lead wire side and makes it A pair of glass members that overlap without touching each other. The second invention is characterized by comprising: a translucent discharge vessel; a phosphor layer formed on the inner surface side of the translucent discharge vessel; and a discharge medium enclosed in the translucent discharge vessel; And a pair of filament electrodes arranged to discharge inside the light-transmitting discharge vessel; a pair of lead wires supporting both ends of the electrode; and a tube stem supporting a pair of lead wires; and respectively fixed The pair of lead wires protrude in a direction slightly parallel to the long axis direction of the filament electrode, and the protruding free tip portions mutually form a pair of glass members with a desired gap in the long axis direction of the lead wire. When printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs of the 1st or 2nd invention, a pair of glass members fixed to a pair of lead wires respectively covered the tube stem with a filament electrode so as to cover it. One part of it, so the electron emitting material scattered from the filament electrode will be deposited on the pair of glass members and deposited, and a conductive material layer will be formed on each glass member. However, the pair of glass members are fixed to a pair of lead wires so as to overlap each other without contacting each other, and the two free front ends overlap each other with a desired gap in the axial direction of the lead wire. For the size of the glass paper, the Chinese National Standard (CNS) A4 specification (210X297 mm) is applied. 552611 A7 B7 V. Description of the invention (5) The two conductive material layers on the component are electrically disconnected. (Please read the precautions on the back before filling in this page.) In particular, the gap in the second invention extends slightly parallel to the length of the filament electrode (electrode axis), which will effectively prevent electrons from being entangled. The voids adhere and accumulate. According to the first or second invention, since a conductive path that forms a radioactive substance is connected between a pair of lead wires, a short circuit between the lead wires of the pair can be prevented, and a point caused by a broken wire can be reliably stopped. Oscillation of the lamp device. In addition, since at least the base of the pair of lead wires and its surroundings are covered by a pair of glass members from the electrodes, even the electron emitting material from the electrodes is wound around the width of the pair of glass members or In the diameter direction, the conductive path is formed by being scattered and deposited on the tube stem, and it is also possible to prevent the electron emission material from being deposited on the base of the tube stem of the pair of lead-in wires and the surrounding portions. Therefore, even when a fluorescent lamp is connected to a lighting device having a high secondary voltage, such as an inverter, it is possible to prevent the abnormal discharge such as half-wave discharge from continuing. The third invention printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is a fluorescent lamp for the first or second invention, in which the protrusion of one of the glass members protrudes from one of the above-mentioned lead-in lines toward the other-hand lead-in line. The length is L 1, and the protruding length of the other glass member protruding from the other leading line toward one of the leading lines is L 2. When the distance between the leading lines of a column is D, L 1 + L 2 > D's formula.
