Screw mounted lamp string
Disclosed is a screw mounted lamp string, comprising a LED lamp string having a number of LED holders connected with each other by wires and corresponding LED bulbs; wherein the screw mounted lamp string comprises a screw head; the live wire contact of the screw head is connected with a corresponding fuse tube, which is connected with the LED lamp string by wires. The screw head of the screw mounted lamp string can directly connect with the screw string, thereby realizing power supply to the LED lamp string, without additional power supply lines, which is saving costs, improving the convenience of using the LED lamp string, and improving the soldering efficiency of the patch LED and the resistance to external force impact, thus enabling the lamp string of the disclosure to have a better application effect in outdoor scenes.
