Creation Description (1) [Technical Field to which the New Type belongs] This creation relates to the structural improvement of cold-cathode lamps, especially the electrode structure of a large-sized cold-cathode lamp with a longer length. [Previous technology] According to the press, CCFL (Cold Cathode Fluorescent Lamp) is widely used in computer scanning, fax machines, advertising because of its advantages such as high surface brightness, long service life and low temperature. In the light box or backlight module, it belongs to a high-pressure mercury discharge lamp. It is coated with a layer of phosphor on the inner wall of the glass tube, and a small amount of inactive gas and a small amount of mercury are sealed inside the tube. This mercury atom is discharged during discharge. Electron impact produces ultraviolet rays, which are converted into visible light by the phosphor. When the power supply is added and the discharge is started, high voltage is directly added from both ends to cause the mercury electrons and gas atoms in the tube to strike each other to generate 2 5 3 · 7 nm ultraviolet rays, which are converted into visible light by the phosphors hitting the tube wall. The tube does not use a filament, so there is no problem of filament burning or breaking, so it has a very reliable service life. As shown in the first figure, it is a schematic diagram of the structure of a general linear cold cathode lamp. Among them, an electrode group 12 is provided on both sides of the cold cathode lamp tube 10, and the electrode groups 12 are respectively provided by two The inner part of the lamp tube 1 is composed of the electrode guide wire 13 which communicates with the outside, but when it is intended to be used for a large-sized φ cold cathode lamp tube with a long length, it is only on the two ends of the electrode due to the long length of the lamp tube. The guide wire 13 generates electrons when it is discharged, and the number of electrons is small, and the probability of collision with mercury atoms is reduced, which further has the disadvantage of a poor light source generation rate.

Creation Note (3) When high-frequency voltage is supplied between the two electrodes 22, the lamp inside the tube will perform the action of the dielectric, and supply power to the lamp. In this way, the mercury atoms inside the lamp will be ionized. While glowing. The key point of this case is that a cold cathode lamp tube 10 is provided with a second electrode group 40 at a position different from the two ends, as shown in the second and third figures, which is located on the outer ring of the tube portion of the lamp tube 11 At the surface, the second electrode group 40 is in the form of a dielectric barrier discharge type electrode. Of course, its electrode 41 can be embedded in the outer edge of the two ends of the lamp tube 1 by using a flexible metal conductor C-clamp 30. (Shown in the fourth figure), or bonded to the outer edge of the lamp tube 1 1. In use, as shown in the fifth figure, when the high-frequency voltage is supplied to the first electrode group 20 and the second electric electrode group 40, the large-sized cold cathode lamp can be removed by the first two sides. The electrode group 20 generates electrons by discharging 50, and the second electrode group 40 simultaneously discharges to generate electrons 50 ', which can collide with mercury atoms 60 in the cold cathode lamp tube 10 to generate ultraviolet rays, and then pass through the phosphor. Transforming into visible light, the screen eliminates the shortcomings of large-size cold-cathode lamps, which rely on the electrode groups at the two ends to generate electrons. The number of electrons reduces the probability of collision, and the light source generation rate is poor.
