[0039] Specifically, the remote control or mobile phone APP is connected to the control chip 20 via Bluetooth to adjust the color, flashing frequency or lighting effect of the colorful lamp beads 30.

[0040] Preferably, there is a predetermined interval between adjacent colorful lamp beads 30 , and each section of the line between adjacent colorful lamp beads 30 can be cut and connected to the control chip 20 to obtain a colorful light string of predetermined length.

[0041] Specifically, the colorful light string is cut into a predetermined length as needed, and one end thereof is connected to the control chip 20 , so that the colorful light beads 30 flash or change colors under the control of the control chip 20 .

[0042] Specifically, the total length of the colorful light string can be 5 meters, 10 meters or 20 meters, and the number of colorful light beads 30 in each meter of the light string is determined according to the specific purpose.

[0043] In this embodiment, a colorful light string 100 is provided with N colorful light beads 30. First, the connecting wire 21 is soldered to the soldering pin on the back of the colorful light bead 30. Then, the address identification code is written for each colorful light bead 30 by serial coding. N colorful light beads 30 need to be written with N consecutive address identification codes. Finally, the colorful light beads 30 with the address identification codes written are connected end to end in sequence to form a colorful light string 100.

[0044] The entire colorful light string 100 is connected to a power source and the control chip 20 . Each colorful lamp bead 30 receives a signal by identifying the address identification code transmitted by the control chip 20 . The driving chip 32 drives the colored LED lamp bead to present a corresponding color.

[0045] The control chip 20 uses control signals to sequentially call each of the colorful lamp beads, #1, #2, #3... #N-1, #N, where N is the number of colorful lamp beads in the colorful light string. The value of N generally ranges from 1 to 300 and can be extended as needed. When one of the colorful lamp beads fails and does not respond, the signal will bypass it and be passed to the next lamp bead. For example, if lamp bead #3 fails and does not respond, the signal will bypass #3 and call lamp bead #4. If lamp bead #4 responds, lamp bead #4 will be driven and operate normally. If lamp bead #4 still does not respond, the signal will bypass #4 and be passed directly to lamp bead #5, and so on, so that each lamp bead receives the driving signal and operates normally. Therefore, in the colorful light string 100, when one or several randomly spaced lamp beads fail, the signal can still be transmitted normally to other healthy lamp beads and enable them to operate normally.

[0046] In the above-mentioned decorative colorful light string 100, the driving chip 32 in each colorful lamp bead 30 is connected in parallel to the control chip 20, and the failure of a single colorful lamp bead 30 will not affect the other lamp beads behind it, and the transparent shell 31 and the transparent bracket enable the colorful lamp bead 30 to have a light-emitting angle of 270 degrees, providing colorful lights to the maximum extent. The transparent shell 31 is injection molded in one step, so that the colorful lamp bead 30 can have a very high waterproof level. Even if the colorful light string is used outdoors, it is safer and more reliable because it has good waterproof function and is connected to a 5V voltage source through the USB interface 12. The transparent shell 31 can be made into various shapes according to the mold, or different appearances can be customized according to user needs, giving people a better user experience. The utility model has a simple structure, is easy to implement, has low cost, and is easy to promote.
