Description of the invention: [Technical field] The present invention relates to a field emission lamp and a method of manufacturing the same, and more particularly to a method for effectively maintaining the required vacuum under normal working conditions by a getter. Field emission lamp and its manufacturing method 'Prior Art】 The lamp is a necessity for daily life, including / transparent glass tube. The inner wall of the glass tube is coated with white or colored fluorescent material, and the interior is filled with water. . The working principle of the fluorescent tube is to use the hot cathode to emit electrons to excite the mercury vapor to emit ultraviolet light, and the ultraviolet light to illuminate the fluorescent material to emit white light or colored light. The neon lamp is a hot cathode light source with high luminous efficiency. However, the mercury vapor used inside is poisonous. When the lamp is broken, the mercury vapor flows out of the outside and is harmful to the environment and the human body. In order to solve the above problems, a cold cathode field emission lamp is provided which includes a cathode and an anode disposed corresponding to the cathode. The cathode surface has no electron-emitting layer, and the anode and the electron-emitting layer are provided with a phosphor layer. When a certain voltage is applied between the cathode and the anode, the electron-emitting layer of the cathode emits electrons, and the phosphor layer of the anode emits light under the bombardment of electrons. The field emission lamp has low energy consumption, high luminous efficiency, and no harm to the environment and the human body. However, for a field emission lamp, a high vacuum sealed package is required inside, that is, the higher the internal vacuum, the better the field emission performance of the lamp. ^ First, as in the technology, the field emission lamp is used to obtain a long life. The vacuum is mainly used to install the getter inside. There are roughly two types, namely, evapotranspiration and concentrated non-evaporable. For the evapotranspiration getter, a planar structure is required inside the field emission lamp to form the getter layer by the pre-evaporation process, which increases the manufacturing cost by 1276135 plus the short circuit or leakage between the electrode leads. This causes the lamp to fail. For the concentrated non-evaporable getter, it is usually disposed at one end of the field emission lamp, so that the vacuum in the field emission lamp is less uniform, that is, the vacuum inside the field emission lamp near the getter is better, and The vacuum away from the position of the getter is poor and affects the field emission performance of the field emission lamp. In view of this, it is indeed necessary to provide a field emission lamp that effectively maintains the vacuum required for normal operation inside. [Summary of the Invention]

The cathode electrode is a V-electrode, one end of which is connected to the cathode emitter 52, and the other end of which extends the mounting member 40 as a cathode terminal 540. Optionally, a spring 56 is disposed between the cathode emitter 52 and the cathode electrode 54. When the cathode emitter 52 is heated or cooled by turning on or off the power source, the emitter 52, the emitter 52 will be thermally expanded or contracted. At this time, the spring % can function as two = knots and balance. The height of the spring 56 is preferably lower than the anode lead ring 360. The cathode electrode 54 functions to provide a cathode terminal 540 for electrically connecting the cathode 5 〇 to the outside. The cathode electrode 54 can be formed in other forms. For example, the end of the cathode emitter 52 can directly serve as the cathode electrode 54 and extend. An electron emission layer 522 is formed on the outer surface of the cathode emitter 540 outside the package 40. The electron emission layer 522 includes a nano material 530, a glass 532, conductive metal particles 534, and a getter. Particle 536.

The inert gas is passed through the process to prevent drying and roasting. The X-raying reaction also prevents the getter from saturating. The purpose of drying is to have 1276135 bare conductive portion 320. The number of the packages 40, 40', the anode electrode 36 and the cathode electrode 54 is the same as the number of the open ends 24, 24' of the glass tube. When the glass tube 20 has an open end 24, a package 40 and an anode electrode are respectively required. 36 and a cathode electrode 54, when the glass tube 20 has two open ends 24, 24', two packages 40, 40', two anode electrodes 36 and two cathode electrodes 54 are required, respectively. In the step (2), the getter particles 536, the conductive metal particles 534, the glass particles and the nano-material 530 are thoroughly mixed in an organic vehicle to form a slurry; the organic carrier is a terpineol as a solvent, and is used as a plasticizer. A mixture of a small amount of ethyl cellulose as a stabilizer and a mixture of a small amount of ethyl cellulose as a stabilizer. The mass percentage of the getter particles 536 in the slurry is 40 to 80%, and the mixing process is preferably 60 to 8 (TC mixing for 3 to 5 hours. For better dispersion of the nano material 530 and obtaining a uniform diameter of the nano material 530) The slurry may further ultrasonically oscillate the organic solvent containing the nano material 530 by using low-power ultrasonic waves, and then centrifuge the same. Step (3), applying the slurry to the surface of the conductor 52; The coating process should be carried out in a clean environment. Preferably, the degree of dust in the environment should be less than 1000/m3. In step (4), the conductive body 520 coated with the slurry is dried at 300 to 600 ° C for 2 lines. The money thus forms an electron emission f/522 on the surface of 52g to obtain a cathode emitter 52, 52, and the cathode emitter 52 and the cathode electrode 54 form a cathode 5〇; 1276135 the carrier is volatilized from the conductor 520. The purpose is to melt the glass particles to bond the getter particles 536, the conductive metal particles 534 and the rice material 530 onto the conductor 520 to form an electron emission 522. In addition, the glazing glass 532 can adjust the overall thermal expansion. system" The electron-emitting layer 522 formed is cracked or broken. To further enhance the field emission of the electron-emitting layer 522, after the drying and baking process, the surface of the electron-emitting layer 522 may be rubbed. The end of the rice material 530 is rubbed to expose the surface of the shot layer 522. " Step (5), assembling the glass tube 20, 20, the anode electrode 36, the cathode 50, and the package members 40, 40, in the glass tube 2, 20 And a sealing material is applied between the packages 40 and 40, and is heated to 4 〇〇 5 〇〇 ° C, and the sealing material is melted to fix the glass tubes 2 〇, 2 (Τ and the package 4 〇, 4 〇, and In the glass tubes 20, 20, a sealed space is formed inside, thereby obtaining field emission lamps 10, 10. The anode electrode 36 is connected to the conductive portions 320 of the anode conductive layers 32, 32, and the other end extends out of the package. The anode terminal is provided with 6, 366. One end of the cathode electrode 54 extends out of the package 4〇, 4〇 to form a cathode terminal 54〇, 540'. The heating process is usually performed in a vacuum environment or in a heating process. Inert gas is added for protection. During the process, the getter particles 536 are activated. The sealing material may be selected from the conventional materials such as a low melting point glass powder having a melting point of 350 to 600° C. The glass frit particles have a small diameter and a low actual melting point. =6〇〇°C. When heated to 400~50 (Γ(:, when the glass frit melts, after cooling, the molten glass solidifies to seal the package 4〇, 4〇, fixed to the glass tube, 20 end and The inside of the glass tube forms a sealed space. When the field emission lamp has the exhaust pipe 60, the glass tube 20, 20, and the sealing member 40, 40 can be externally connected to the exhaust pipe 60 by a 15 1276135 vacuum pump. The glass doors 20, 20 have a certain degree of vacuum inside, and then the ends of the exhaustors 60 are sealed and the glass tubes 2, 2, and sealed with the packages 40, 4'.综 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application in accordance with the law. However, the above description is only the preferred embodiment of the present invention, and those skilled in the art will be able to include the equivalent modifications or variations of the invention in the spirit of the invention.
