Abstract
The invention relates to a continuous current control circuit module of series string bulbs type, 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 is especially a Zener diode with a tiny volume. The shunt will thus provide a secure electrical connection of the light string whenever any bulb is burn out or broken.
Claims2
A continuous current control circuit module of series string bulbs including a light string with electrical wires connecting with several bulb assemblies in series, wherein each bulb assembly including a shell, a bulb holder, and a bulb;
- the improvement is in that a Zener diode is connected with the bulb in parallel in each bulb assembly.
