[0051] See also Figure 7 As shown, when the wire L1 is positive and the wire L2 is negative, the lamp bead LED1 is on; when the wire L3 is positive and the wire L2 is negative, the lamp bead LED2 is on; when the wire L2 is positive and the wire L1 is negative, the lamp bead LED3 is on; when the wire L2 is positive and the wire L3 is negative, the lamp bead LED4 is on; in this way, the lamp bead LED1, the lamp bead LED2, the lamp bead LED3, and the lamp bead LED4 are lit one by one, showing a flowing water effect of 4 lights in a group, and so on, more groups of flowing water light groups can be realized.

[0052] Among them, wire L3 is sometimes positive and sometimes negative, while the existing single-color constant-on lamp beads on the market have fixed positive and negative poles (when the positive and negative poles are swapped to power the lamp beads, the lamp beads will not light up). In order to keep the lamp beads between wires L3 and L4 visually always on, it is necessary to specially develop a single-color lamp bead that can light up regardless of the direction of power supply and has the same luminous color, which is referred to as "single-color electrodeless lamp bead", i.e. LED17, LED18... The principle of single-color electrodeless lamp beads is: two light emitters G and R in opposite directions are installed in a lamp bead bracket, and the light emitted by light emitters G and R has the same color; when wire L3 is positive, wire L4 can be negative, at this time light emitter G works and light emitter R stops; when wire L3 needs to be negative, wire L4 can be positive, at this time light emitter G stops and light emitter R works.

[0053] In this way, it is achieved that the lamp beads between the wires L1, L2 and L3 can flow while the monochrome electrodeless lamp beads between the wires L3 and L4 can remain in a constantly lit state; in addition, when only the wires L1, L2 and L3 are powered, and the wire L4 is out of power, the 4-lamp flowing effect can be displayed separately; when only the wires L3 and L4 are powered, and the wires L1 and L2 are out of power, the constantly lit effect can be displayed separately.

[0054] When the light string of the present invention emits a constant light, it can simultaneously display a 4-light flowing water effect; for example, when the constant light is warm yellow light and the 4-light flowing water light is white light, when multiple light strings are hung on the ceiling in an array, a visual feast of a starry sky and shooting stars can be presented.

[0055] In this utility model, the components and their models and connection relationships not shown are Figures 2 to 7 The specific circuit diagram has been marked and will not be repeated here.

[0056] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
