The screw mounted lamp string comprises a screw head 5. The live wire contact of the screw head 5 is connected with a corresponding fuse tube 6, which is connected with the LED lamp string 1 by wires 4. In this embodiment, the LED lamp string 1 can be directly connected to the screw socket of the screw string through the screw head 5, so that the LED bulbs 3 can be powered without any additional power supply wires. Among these, the fuse tube 6 is mainly used to protect the LED lamp string 1 from potential safety hazards caused by instantaneous high current when short circuiting occurs.

(8) Specifically, referring to FIG. 2, the LED bulbs 3 comprise a positive electrode bracket 7, a negative electrode bracket 8, a patch LED 9, and an encapsulation gel 10. The positive and negative ends of the patch LED 9 are respectively fixed to the positive electrode bracket 7 and the negative electrode bracket 8, and the connection ends of the positive electrode bracket 7 and the negative electrode bracket 8 to the patch LED 9 are planar. In this embodiment, instead of traditional wiring connection, the connection points at the positive and negative ends of the patch LED 9 are directly connected to the corresponding positive electrode bracket 7 and negative electrode bracket 8. On the one hand, the problem of external force impact is well solved, the patch LED 9 is fixed on the connection end of the bracket, the connection end is a planar with large soldering area compared with bowl groove, and it is easier to solder and stronger. On the other hand, the planar connection of the positive electrode bracket 7 and the negative electrode bracket 8 can also increase the luminous angle of the patch LED 9 to 180 degrees, which can solve the problem of small luminous angle of the conventional bowl bracket.

(9) Specifically, the LED lamp holders 2 are connected with each other in series or in parallel.

(10) Specifically, referring to FIG. 4, a bridge rectifier encapsulation member 12, consisting of four rectifier diodes 11, is also provided between the screw head 5 and the LED lamp string 1. In this embodiment, the bridge rectifier encapsulation member 12 uses wire 4 to connect with screw head 5 and LED lamp string 1. The screw head 5 obtains AC power through screw holder 2. The AC power passes through the fuse tube 6 and then is rectified by the bridge rectifier encapsulation member 12 to supply DC power to the LED lamp string 1.

(11) Specifically, the LED lamp holder 2 is provided with a corresponding current-limiting resistor 13 inside. In this embodiment, a current-limiting resistor 13 is added to the LED holder 2 to control the current through the LED bulbs 3 not to exceed the rated operating current, thus ensuring service life of the LED lamp string 1.

(12) Specifically, the surface of the patch LED 9 has a phosphor layer.
