ABSTRACT:
The invention relates to a continuous current control circuit module of series string bulbs type (II), which can maintain the normal current and voltage across each of the bulbs when any of series connected bulbs burn out. The string includes a shunt in every bulb assemblies, which has an auxiliary conductive apparatus including an SCR (silicon controlled rectifier), a TRIAC (THYristor), a DIAC (trigger diode), or a Transistor with resistors and is parallel connecting related to the bulb. The shunt will thus provide a secure electrical connection of the light string whenever any bulb is burn out or broken.
