碩士 === 南榮技術學院 === 工程科技研究所碩士在職專班 === 97 === The illumination is humanity's primary need, along with the low-pressure gas electric discharge fluorescent lamp (is named daylight lamp) the appearance, because its luminous efficiency substitutes for the incandescent lamp bulb gradually, however the fluorescent lamp because of its negative resistance characteristic, cannot the direct connection in the alternating current supply, therefore needs joins the stabilizer between the fluorescence tube and the power source, lightens the tube and the steady state current change. The fluorescent lamp uses traditional electromagnetic stabilizer, because uses the silicon sheet steel ferrite core and the enamel-insulated wire coil constitutes, causes the luminous efficiency not to be good. Along with modern electronic technology's development breakthrough, in the emphasis energy conservation province electricity's time and under the energy laws' and regulations' request, the electronic ballast becomes lighting attachment's mainstream gradually. The use electron ballast lights a lamp, surpasses the general traditional stabilizer besides the performance, may design exceptionally detects the electric circuit, when the tube has the unusual condition, triggers the protection circuit movement rapidly, the closure control actuation signal, avoids the electronic ballast damage, and safety of attendants. This research in view of fluorescent lamp use electronic ballast, regarding tube last stage effect phenomenon, when the filament consumption creates the electron emission insufficiency or is unable to have the electron emission, has the tube electric current asymmetrical phenomenon, in the article proposed that the related tube test measure, provides the electronic stabilizer designs when the effective countermeasure, achieves detects completely protects and realizes many kinds of pattern tubes to use in common the goal, provides the user a more convenient use and the security.
