[0003] The more common light strings on the market are usually single, and as light strings, they can only perform simple flashing, breathing, and flowing light controls. The wattage of the lamp beads in the light string is limited, resulting in the maximum peak nits of the lamp beads being restricted, and the overall effect is relatively simple.

[0013] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0026] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 — Figure 3 :

[0027] A combination light string includes a power adapter 1, a control box 2 connected at one end of the adapter 1 via a wire, a first light string 3 powered by 36 volts and a second light string 4 powered by 5 volts connected to the control box 2, the first light string 3 including a plurality of first lamp beads 5 connected in parallel or in series on two thick wires 30, the second light string 4 including three thin wires 40 and a plurality of second lamp beads 6, the second lamp beads 6 being alternately connected in parallel to two adjacent thin wires 40, and the first light string 3 and the second light string 4 being twisted together.

[0028] In the above structure, the adapter power supply steps down the 220 volts to a voltage of 5 to 36 volts, and performs voltage division in the control box, providing the voltage of the first light string to maintain the input voltage of the control box, and providing the voltage of the second light string to take a voltage reduction process so that the second light string can have an input voltage of 5 volts.

[0029] The two output voltages, 36V and 5V, correspond to two different voltage requirements for light strings. In actual use, the two second lamp beads use three thin wires and are powered by three-phase electricity. The three-phase electricity from any two adjacent thin wires provides a more stable waveform quality for the second lamp bead, making the light more stable.

[0030] Preferably, the first lamp bead 5 includes a columnar lamp bead body 50, in which an LED lamp bead 51 is arranged, and the positive and negative ends of the LED lamp bead 51 are respectively connected to two strands of the thick wires 30, and two adjacent LED lamp beads 51 are connected in parallel or in series and then in parallel.

[0031] In the above structure, the thick wires connected to the positive electrodes of two adjacent first lamp beads are connected, and the thick wires connected to the negative electrodes are connected to each other, with the entire arrangement being connected in parallel or in a combination of parallel-first and then series. This arrangement allows the first light string to be trimmed to meet different length requirements without affecting the first light string.

[0032] In addition, the first and second light strings perform certain lighting modes such as flowing light, breathing, constant light and flashing, and each light string is PWM-controlled through the control box. This control method is an application of existing technology.

[0033] Moreover, the light strings with two voltages, 36V and 5V, achieve different lighting intensities and present different lighting effects, thus providing more display effects.

[0034] Preferably, the lamp bead body 50 is wrapped with an insulating rubber sleeve 52 , and the insulating rubber sleeve 52 is filled with insulating glue 53 , and the insulating glue 53 isolates the two thick wires 30 connected to the positive electrode and the negative electrode respectively.

[0035] The insulating glue 53 can separate the thick wires connected to the positive and negative electrodes to prevent short circuits.

[0036] Preferably, the thick wires 30 connected to the positive and negative electrodes of the LED lamp beads 51 are all insulated wires to enhance insulation.

[0037] Preferably, the second lamp bead 6 is fixed to two adjacent thin wires 40 by welding, and the surface of the second lamp bead 6 is covered with a transparent insulating glue 60 .

[0038] Compared with the first lamp bead 5, the second lamp bead 6 is welded and spot-coated with resin insulating glue to achieve waterproof protection for the lamp bead.

[0039] Preferably, the first light string 3 and the second light string 4 are both twisted together by rotation, and the first light string 3 and the second light string 4 in the combined light string are arranged at intervals. When the first light string 3 and the second light string 4 rotate, they will entangle with each other when they come into contact, thereby forming a spiral winding form, and the first light string 3 and the second light string 4 can be arranged in an alternating manner.

[0040] Preferably, the thick wire 30 is provided with eight or more copper wires, and the thin wire 40 is provided with two or less copper wires. The thick wire 30 with more copper wires can have a better carrying capacity for 12 volts.

[0041] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
