具体实施方式 detailed description
图 1中， 两条灯丝 6、 7分别安装在电极支架 2芯柱上的固定电极导丝 4和固定电 极导丝 5上， 两条灯丝 12、 13分别安装在电极支架 3芯柱上的固定电极导丝 10和固定 电极导丝 11上， 四条灯丝分别涂上电子粉后， 使电极支架 2和电极支架 3分别拥有二 个电极， 将电极支架 2和电极支架 3放进荧光粉管的两个输入端内， 其芯柱喇叭口 9、 14分别与荧光灯粉管的两个输入端口 8、 15密封固定连接， 通过其它制灯工艺，加工成 双电极荧光灯的成品灯管。由于荧光灯管启动的物理过程中，灯管在有效电压的作用下， 灯管两端的电极间气体先发生电击穿， 然后引起辉光放电， 继而由辉光放电转移到弧光 放电， 形成热离子电弧， 最后达到局部平衡，' 荧光灯正常燃点。 造成阴极发射材料损耗 主要原因是溅射和蒸发引起的， 启动时电极爆炸温升引起阴极发射物质大片剥离， 会明 显地减少涂层的储存量， 而正常燃点时是造成氧化材料蒸发的原因， 荧光灯的工作寿命 实际上是由电极决定的， 当阴极不能从氧化物涂层得到丰富的热发射时， 灯管不是不容 易启动， 就是在辉光放电上 "搁浅"， 这将 Λ所有的剩余阴极材料很快溅完， 而灯也就 算坏了。 因而有效地提高分解激活后氧化物涂层的储存量， 就能有效地延长电极的使用
寿命。 实验发现， 在荧光灯管两端的电极支架上分别安装两条电极， 在管内低气压的条 件下， 每端主要由电阻值小的一条电极进行阴极放电的物理现象， 实践说明每端电极支 架芯柱上拥有二条阴极涂层比现有技术每端电极支架芯柱上只有一条阴极涂层增加一 倍， 因而有效地延长了电极的使用寿命， 亦是有效地提高了荧光灯管的工作寿命。采用 双电极支架适用于直型、 环型、 紧凑型和组合型荧光灯管的应用， 灯管直径为 12mn！〜 32mm, 灯管功率为 15W〜300W。 In Fig. 1, two filaments 6, 7 are respectively mounted on the fixed electrode guide wire 4 and the fixed electrode guide wire 5 on the electrode holder 2, and the two filaments 12 and 13 are respectively fixed on the electrode holder 3 core. On the electrode guide wire 10 and the fixed electrode guide wire 11, after the four filaments are respectively coated with the electronic powder, the electrode holder 2 and the electrode holder 3 respectively have two electrodes, and the electrode holder 2 and the electrode holder 3 are placed into the phosphor tube. In the input end, the stem flares 9, 14 are respectively sealed and fixedly connected with the two input ports 8, 15 of the fluorescent powder tube, and processed into a finished lamp of the two-electrode fluorescent lamp by other lamp making processes. Due to the effective process of the fluorescent tube during the physical process of the fluorescent tube, the gas between the electrodes at both ends of the tube first undergoes electrical breakdown, then causes a glow discharge, which is then transferred from the glow discharge to the arc discharge to form a thermionic ion. The arc, finally reaching the local balance, 'the fluorescent light is normally ignited. The main cause of the loss of the cathode emission material is caused by sputtering and evaporation. The temperature rise of the electrode explosion at the start-up causes a large strip of the cathode emission material to be peeled off, which will obviously reduce the storage amount of the coating, and the normal ignition point is the cause of the evaporation of the oxidized material. The working life of a fluorescent lamp is actually determined by the electrode. When the cathode cannot obtain rich thermal emission from the oxide coating, the lamp is not easy to start, or it is "grounded" on the glow discharge, which will lick all the remaining The cathode material quickly splatters and the lamp is broken. Therefore, effectively increasing the storage amount of the oxide coating after decomposition activation can effectively extend the use of the electrode. Life expectancy. It is found that two electrodes are respectively mounted on the electrode holders at both ends of the fluorescent tube. Under the condition of low pressure inside the tube, the physical phenomenon of cathode discharge is mainly performed by one electrode with a small resistance value at each end, and practice shows that each end of the electrode holder core column The presence of two cathode coatings is twice as large as that of the prior art electrode holder core column, thereby effectively prolonging the service life of the electrode and effectively improving the working life of the fluorescent tube. The two-electrode holder is suitable for straight, ring, compact and combined fluorescent tubes. The diameter of the tube is 12mn! ~ 32mm, lamp power is 15W~300W.
图 2中， 每端电极支架芯柱上有四条固定电极导丝 A、 Al、 B、 Bl， 电极导丝 A与 A1连接， 电极导丝 B与 B1连接， 灯丝 4安装在固定电极导丝 A、 B上， 灯丝 5安装在固 定电极导丝 Al、 B1上， 涂上电子粉， 使电极支架 2和电极支架 3上分别拥有二条电极, 并将电极支架 2和电极支架 3分别放进荧光灯粉管 1的两个输入端内，两个电极支架的 喇叭口与灯管的两个输入端分别密封连接， 通过其它制灯工艺， 加工成双电极荧光灯的 成品灯管。 其工作原理与图 1是一样的。 In Fig. 2, there are four fixed electrode guide wires A, Al, B, and Bl on each end of the electrode holder, the electrode guide wire A is connected with A1, the electrode guide wire B is connected with B1, and the filament 4 is mounted on the fixed electrode guide wire A. On the B, the filament 5 is mounted on the fixed electrode guide wires A1, B1, and coated with electronic powder, so that the electrode holder 2 and the electrode holder 3 respectively have two electrodes, and the electrode holder 2 and the electrode holder 3 are respectively placed in the fluorescent lamp powder. In the two input ends of the tube 1, the bell mouths of the two electrode holders are respectively sealedly connected with the two input ends of the lamp tube, and processed into a finished lamp tube of the two-electrode fluorescent lamp by other lamp making processes. Its working principle is the same as that of Figure 1.
如图 3所示， E形金属挡屏 15固定在电极支架 2芯柱上的独立导丝 14上， E形金 属挡屏 17固定在电极支架 3芯柱上的独立导丝 16上。 E形金属挡屏 15将电极支架 2 上的电极 4、 5分别包围， 屏与电路不通。 E形金属挡屏 17将电极支架 3上的电极 6、 7 分别包围， 屏与电路不通。 在荧光灯管启动和正常燃点的过程中， E形金属挡屏有效地 避免了同在一个电极支架上两条电极互相污染和防止阴极蒸发管壁， 同时， 由于电极上 没有别的收集阳极电流的装置， 大部分电流必须由发射线圈本身接收， 并且这部分功率 就是所要求的加热发射线圈能量中的很大一½分， 增加 E形金属挡屏， 对等离子体的作 用是减少阳极附近电弧截面， 增加电流密度， 因而也增加了阴极附近的电子密度， 这也 减少了阴极位降， 有效地提高了荧光灯管的效率。
As shown in Fig. 3, the E-shaped metal screen 15 is fixed to the independent guide wire 14 on the electrode holder 2, and the E-shaped metal screen 17 is fixed to the independent guide wire 16 on the electrode holder 3. The E-shaped metal screen 15 encloses the electrodes 4 and 5 on the electrode holder 2, respectively, and the screen and the circuit are not connected. The E-shaped metal screen 17 encloses the electrodes 6, 7 on the electrode holder 3, respectively, and the screen and the circuit are not connected. During the startup of the fluorescent tube and the normal ignition point, the E-shaped metal screen effectively avoids contamination of the two electrodes on the same electrode holder and prevents the cathode from evaporating the tube wall. At the same time, there is no other anode current collected on the electrode. The device, most of the current must be received by the transmitting coil itself, and this part of the power is a very large 1⁄2 of the required heating coil energy. The E-shaped metal screen is added. The effect on the plasma is to reduce the arc cross section near the anode. Increasing the current density, thus also increasing the electron density near the cathode, which also reduces the cathode drop, effectively improving the efficiency of the fluorescent tube.
