New Description: [New Technical Field] This creation provides an electron and ion induction device, and more particularly to an electron and ion induction technique applied to a cup electrode of a cold cathode lamp. [Prior Art] Press, Cold Cathode Fluorescent Lamp (CCFL) is a low-pressure mercury gas discharge lamp. It has a small lamp tube, simple structure, small temperature rise of the lamp tube, high brightness of the surface of the lamp tube, and easy processing. It has been widely used in a variety of shapes and long service life, so it has been widely used in various advertising light boxes, scanners and display backlights. It is also known that the above-mentioned cold cathode lamp tube is mainly provided with an electrode 2b (shown in FIG. 14) on the double end side of the lamp tube 10b, and the inner wall of the lamp tube 10b is coated with a layer of phosphor powder 5b and is disposed on the tube. 10b is internally sealed with a small amount of inert gas (such as argon Ar, 氖Ne) and trace mercury (mercury Hg), and a double-ended side of the lamp tube l〇b is provided with a metal lead 3b for external power supply, the electrode 2b and the lead 3b A rod-shaped conductive member 7b' is connected between the conductive member 7b and the conductive member 7b is wrapped in a glass bead 6b for positioning and bonding to the end side of the bulb 10b. When the electrode 2b at both ends of the bulb 10b is applied with a sufficiently high voltage (as shown in FIG. 14), the free electrons between the electrodes 2b are accelerated to collide, causing the gas inside the bulb 10b to be excited (or Said ionization), when the excited gas returns to the steady state, it will emit 253.7nm ultraviolet light (UV), which will stimulate the fluorescent powder 5b on the tube wall to produce the desired visible light, and the ionized gas will be The electric field is accelerated again to generate more impact, causing the electrode 2b to be struck by the M357701 to generate secondary electrons, which causes the gas in the lamp tube l〇b to have a chain reaction, so that there are enough electrons and ions in the lamp tube l〇b. The reaction produces light, which is the discharge effect; in addition, the electrodes 2b are usually made into a cup shape, which can have a relatively stable discharge effect, and the electrodes 2b are usually made of recorded (Ni) metal. . However, the disadvantage is that during the illumination of the cold cathode lamp, the electrons and ions in the lamp tube 10b are accelerated to the cup electrodes 2b, and the cup of the cup electrode 2b is bombarded with a certain kinetic energy. The bottom surface 23b of the opening 22b and the cup groove 21b causes an overflow phenomenon of the splash of the righteousness, and particularly the groove wall 24b adjacent to the bottom surface 23b of the cup groove 21b, which is eroded by electrons and ion bombardment which are rebounded by the bottom surface 23b of the cup groove 21b. The phenomenon is particularly serious, and may even cause the electrode 2b to break. At the same time, nickel and mercury compounds are generated during the bombardment process, and the mercury and inert gas in the lamp 1b are consumed, and the splashed nickel causes the lamp to lb Blackening occurs at both ends; this will affect the performance and life of the cold cathode lamp. In addition, the above electrode 2b can also be conventionally fabricated using molybdenum (Mo) or niobium (Nb) which is superior in impact resistance to nickel; however, molybdenum or niobium is expensive, ' ® and its soldering is difficult. In the prior patented technology, a national patent No. 2,721,224 patent publication, • a cold cathode, a tube that is placed on the inner and outer surfaces of a cup electrode, or a (four) material, to protect the electrode from electrons Erosion with ion bombardment; however, the coating of the inner and outer surfaces of the electrode by electroplating or gold secret injection technology is in the technical difficulty and high production cost, and is coated on the surface of the electrode. Or the thickness of the sharp material is limited, so it is difficult to greatly increase the service life of the cold cathode lamp. In the prior patented technology, - US Pat. No. 6963164B2 discloses a M357701 cold-cathode tube coated with a cup-shaped electrode wrapped with a bombardable ceramic material to protect the electrode cup from electron and ion bombardment. However, the pottery material does not effectively protect the bottom surface of the electrode cup and the groove wall adjacent to the bottom surface of the cup.

The low-power electron (4)_ is tungsten, _, sharp, molybdenum, niobium, titanium or tantalum, or an alloy of tungsten, molybdenum, sharp, titanium or tantalum. The electric attraction terminal has a tapered shape, a spherical shape, a column shape or a disk shape. The electro-acceptance terminal is penetrated and the (4) squaring method is implanted on the electrode. However, in order to clearly and fully disclose the present invention, a preferred embodiment of the present invention will be described, and the detailed description will be given as follows: [Embodiment] The following examples are provided to illustrate the purpose and preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Referring first to FIG. 1, a perspective view of a first embodiment of the present invention is disclosed, and an electronic and ion-inducing device for the cold cathode fluorescent lamp of the present invention is described with reference to FIG. 2 and FIG. 3, including the inner end side of the lamp tube 10. An electrode 2 having a cup shape and having a cup groove 21, and the cup groove 21 has a cup opening 22 which opens toward the other end side of the tube 1 . In this embodiment, the electrode 2 can be implemented in a multiple array, and the electrode 2 is disposed on the inner double end side of the lamp tube 1 (as shown in FIG. 1 to FIG. 3 ), and the inner wall of the lamp tube 10 is coated with a layer. Fluorescent powder 5, and a small amount of inert gas (such as argon, helium) and trace mercury (mercury) are sealed inside the lamp tube 10, and a metal lead 3 of an external power source is respectively disposed on the double end side of the lamp tube 1〇M357701. l Make the electrode 2 times longer. Use this lead 3 to turn on the external power supply. According to the above implementation environment, the author creates a soldering terminal 41 (shown in FIG. 1 to FIG. 3) in a penetrating manner on the bottom surface of the cup slot 21. The attracting terminal 41 is extended to form a lead. The extension portion 4 of the 3 is made of a low work function electron-emitting material, which can induce electrons and ions in the tube 1 to bombard the attracting terminal 41, and is resistant to attack by the bombardment of the ions and ions. The attracting terminal 41 can be tapered in this embodiment, and has a relatively low electric %, and the low-function electron-emitting material can be molybdenum in this embodiment, and the extending portion 40 is wrapped in a glass bead 6 Inside, to position and bond to the end side of the tube 10. In addition, the attracting terminals 42, 43, 44 may also be spherical, columnar or disk-shaped (as shown in FIG. 4 to FIG. 6), and the low work function electron emitting material may also be tungsten, tantalum, titanium or tantalum. Etc., or an alloy of tungsten, molybdenum, niobium, titanium or tantalum, which is composed of the above components, can be used to implement the present invention, especially when the electrode 2 of the double end of the lamp tube 10 is sufficiently high via the lead 3. When the voltage is applied (as shown in Figure 2), the free electrons in the lamp tube 1 are accelerated, and collide with each other to generate more free electrons and ions, so that the mercury atoms in the lamp tube are impacted during the discharge to generate ultraviolet light. And the ultraviolet light excites the phosphor powder 5 on the wall of the tube 10 to generate visible light; during this period, electrons and ions in the tube 1 are accelerated to the cup electrodes 2 (as shown in FIG. 3). And most of the electrons and ions are attracted by the attracting terminal 41, and the bombarding of the attracting terminal 41' is used to slow down the wall 2 of the electrode 2 adjacent to the bottom surface 23 of the cup 21 by electron and ion bombardment. M357701 According to the above, it can be understood that the author is directly provided with an electric attraction terminal 41 made of a material capable of inducing electrons and ions and resistant to bombardment splashing in the electrode 2, so as to attract electrons and ions accelerated to the electrode 2, and The electrode 2 is slowed down by electron and ion bombardment to save the consumption of the mining, so that the blackening of the double end of the lamp 10 can be slowed down, so that the amount of mercury enclosed in the lamp 10 can be reduced, thereby increasing the cold. The use of cathode lamps. _ performance and longevity, and further achieve low cost and environmental benefits. Referring to FIG. 7, a cross-sectional view of the second embodiment of the present invention is disclosed. The present invention is constructed by implanting a attracting terminal 41a in a tightly fitting manner on the bottom surface 23a of the cup 21a of the cup electrode 2a. Conducting with the lead 3a; the attracting terminal 41a is made of a low work function electron emitting material, and can induce electrons and ions in the tube l〇a to bombard the attracting terminal 41a, and is resistant to the electrons and ions. Bombardment erosion; the electric attraction terminal 41a can be tapered in the present embodiment, and has a higher electric field, and the low work function electron emission material can be turned over in this embodiment; the electrode 2a and the lead 3a are combined with one rod The conductive member 7a is electrically connected to the attracting terminal 41a and the lead 3a. The conductive member 7a is wrapped in the glass bead 6a to be positioned and coupled to the end side of the bulb 10a, and the attracting terminal 41a can correspond to On the conductive element 7a. In addition, the low work function electron emissive material may also be tungsten, tantalum, titanium or tantalum, or an alloy of tungsten, molybdenum, niobium, titanium or tantalum, and the attracting terminals 42a, 43a, 44a may also be spherical. The column or disk shape (as shown in FIG. 8 to FIG. 1B), the soldering terminal 42a can also be implanted in the electrode 2a, and the soldering terminal 43a can also be implanted in the electrode 2a. In addition, the disk-shaped electric attraction terminal 44a can be directly fitted in the cup groove 21a and attached to the bottom surface 23a of the cup groove 21a; the remaining components and embodiments are equivalent to 11 M357701. . Accordingly, the present invention directly places the electric attraction terminal 41a made of a material capable of inducing electrons and ions and resistant to bombardment splashing in the electrode 2a to attract electrons and ions accelerated to the electrode 2a, and to slow down the electrode 2a. The bombardment of electrons and ions erodes to save the consumption of mercury, so that the blackening of the double-end of the lamp can be slowed down, so it can also reduce the amount of mercury enclosed in the lamp 10 a. The performance and life of cold cathode lamps are further improved by low cost and environmental protection. • In addition, in order to verify the feasibility of the electronic and ion-inducing device of this creation, it is attached to the blackening size, mercury consumption and tube voltage for the creation under the accelerated test condition of tube current 14.5 mA. The specific data of the accelerated experiment is described in detail with the specific implementation results of this creation, and compared with the traditional cold cathode fluorescent tube. Chen Ru explained the following: Please refer to the figure to reveal the original cold cathode lamp The curve of the blackening size of the tube; wherein the curve 81 is the blackening size curve of the cold cathode fluorescent tube of the present invention, the curve 81b is the blackening ruler curve of the conventional cold cathode fluorescent tube; The blackened area produced by this creation after 60 hours of use is 1.5mm less than that of the traditional cold cathode lamp, and the blackened area produced by this creation after 150 hours of use is also 1.5mm less than the conventional cold cathode lamp; It can be seen that the present invention can effectively improve the blackening phenomenon of the double-end of the cold cathode lamp and improve the performance of the cold cathode lamp. Referring to Figure 12, a graph showing the mercury consumption of the present invention and a conventional cold cathode lamp; wherein curve 82 is the mercury consumption curve of the cold cathode lamp of the present invention, and curve 82b is a conventional cold cathode. Mercury consumption curve of the lamp; compared with the known, the mercury 12 M357701 consumed after 15 hours of use is less than that of the conventional cold cathode lamp; this shows that the creation can effectively improve the cold cathode lamp. By controlling the consumption of mercury and increasing the service life of the cold cathode lamp, it is possible to reduce the amount of mercury enclosed in the lamp and to provide environmental benefits. See Figure 13' to reveal the curve of the tube voltage of this creation and the traditional cold cathode lamp; where 'curve 83 is the tube voltage curve of the created cold cathode lamp, curve 83b is the traditional cold cathode lamp The tube voltage curve of the tube; knowing that the tube voltage after 15G hours of use is 25V lower than the traditional cold cathode, it can be seen that the creation can also effectively improve the power consumption of the cold cathode lamp 5, thereby providing energy saving benefits.
