Description

1262746 IX. Description of the Invention: [Technical Field] The present invention relates to a method and apparatus for detecting aging of a fluorescent tube, and more particularly to a method and apparatus for accurately detecting the degree of aging of a fluorescent tube in a short period of time. * [First Technology] Since Edison's invention of Incandescent Lamp in 1879, it has completely changed the working hours of cockroaches, and also effectively extended people's work and entertainment time, so that business and industry can flourish. However, due to its low luminous efficiency and short service life, incandescent lamps have gradually been replaced by fluorescent lamps (Flu (10) scent Lamp). As shown in Fig. 1, it is a conventional assembly circuit of the starter 10, the fluorescent lamp 20, the inductive ballast 30, and the plug 4A. When the power is turned on, the starter 10 is in a short-circuit state. At this time, the filaments at both ends of the fluorescent lamp 2 pass current, and the filament/dish rises and emits electrons to achieve the purpose of pre-hearting (Prehearting). After the warm-up procedure is completed, the starter IG becomes an open circuit. At this time, the ballast is seamed—the light causes the filament to ignite the electron, and then the bright fluorescent tube 20 is turned on. After the fluorescent tube 20 is turned on, the starter 1〇 will remain open, and the inductive ballast 30 will act as a steady current. The conventional starter contains a movable electric current, and the distance between the two poles of the fixed electrode is much smaller than the distance between the filaments of the fluorescent tube, so the power source-force: the day L, will first generate a discharge phenomenon, so that high heat is generated between the electrodes, __ hemp and fixed electric two touch this traditional start to have the disadvantages of poor startability, maintenance is not easy, and at the end of the life of the lamp _, f will cause damage to the ballast due to excessive preheating current. In order to improve the above-mentioned i, the first to start: the shortcomings, and the emergence of electronic start-break. With the development of power electronics technology, there are a variety of electronic money machines, which not only have high luminous efficiency, high work factor, no _, light weight, etc., but also can extend the lamp to turn Life and dimming function [1-5] One of the important purposes of the 种° Egg Light 4 starter is to make the fluorescent lamp have a good start* and slow down the aging of the light. However, there is currently no measurable fluorescent lamp aging in the market.
