Description of the Invention (1) The present invention is a kind of dimmable fluorescent lamp circuit, especially one »Dimming Fan Yuanguang, Pan Ding "Dimmable fluorescent lamp circuit J, which can save energy and light up at any point under any brightness value. Press. The starting circuit and stabilization circuit of fluorescent lamps have been upgraded from traditional ferromagnetic ballasts to high power factors. And electronic ballast with high luminous efficiency. As for the dimming technology, various conventional fluorescent lamp circuits with a dimming function currently have a common disadvantage, that is, the qualitative nature of the lamp will change the maximum dimming and change β. The reason is limited by the light-emitting mechanism of fluorescent lamps. In a wide range of dimming areas, although the dimming decreases, the search management characteristics become more uncertain, which not only causes the lights to flicker, but also causes the life of the tubes to decrease sharply. In the experimental research of the inventor, it was found that the lamp system is in an extremely unstable state within the dimming range of about 70¾ to 10¾; in addition, the fluorescent lamp in this garden cannot be instantaneously turned on. That is, when the fluorescent lamp is in the extinguished state, if any dimming amount in this fan garden is used to immediately light up the lamp tube, it usually fails. However, the inventor is a tireless spirit, and by It is supplemented by its professional knowledge and practice laboratory, and in view of the lack of dimmable light circuit and the improvement of κ, the invention has been carefully developed. The invention provides a dimmable fluorescent lamp. The circuit is composed of a central processing army, a transformer circuit, a frequency conversion circuit, a lighting circuit and a lamp tube. It uses a central processing unit to control the voltage transformation and frequency conversion circuit, so that the voltage transformation and frequency conversion circuits are preset. The voltage and frequency signals are modulated, and M controls the lighting circuit to drive the lamp tube; the fluorescent lamp circuit formed by this has the advantages of wide dimming range, Hong Kong setting, high resolution, energy saving, and instant illumination.
