Abstract: A lighting rope for an accessory includes a power control unit, a rope sleeve, and a flexible printed circuit board provided inside and extending along the rope sleeve. The flexible printed circuit board is sleeved with the rope sleeve by using a heat shrinkable film wrapping process. The flexible printed circuit board is provided in a length direction with a plurality of light-emitting diodes (LEDs) arranged at intervals. The power supply control unit includes a push button and a power supply battery. The LEDs are powered by the power supply battery and controlled by the push button to emit light. A semiconductor process is used to mount the LEDs on the flexible printed circuit board and the heat shrinkable film wrapping process is used to wrap the rope sleeve outside the flexible printed circuit board, greatly reducing the diameter of the existing lighting rope.
