Abstract
A novel LED lamp string is provided whose LED lamps are protected from current/voltage fluctuation. The gist of the present invention lies in the configuration of a number of resistors series-connected to the LED lamps along the cable of the LED lamp string. With the resistors, the current and voltage along the cable are stable with no sudden high or low, and therefore the LED lamps have longer operational lives.
Claims4
A LED lamp string comprising:
- a plug;
- a cable connected to the plug;
- a plurality of LED lamps connected to the cable;
- and
- a plurality of resistors series-connected to the LED lamps along and by the cable;
- wherein, with the installation of the resistors, the current and voltage along the cable are stable and the LED lamps have extended operational lives.
