Abstract:
     The electronic fluorescent lamp is consisted of interference killer circuit, overheat step-down circuit, rectification and filter circuit, high-frequency generation and LC resonant circuit, metal holder, upper lampshade, bracket of tube, fluorecent tube and lower lampshade. Since the bimetal temp.-controlled switch and the step-down circuit are used in the overheat step-down circuit the transistor can not be damaged when overheating. When temperature is normal the overheat step-down circuit does not work, the light flux of fluorecent tube is normal.
