A waterproof flexible LED light bar equipped with an oxygenation pipe and a manufacturing method thereof. The water-proof flexible LED light bar equipped with an oxygenation pipe comprises an LED light string (2). The LED light string (2) comprises light body circuit boards (22), serial electrical connection wires (23), and a power supply module (3). Each light body circuit board (22) is electrically connected to an LED luminophor (21). The waterproof flexible LED light bar further comprises a flexible waterproof encapsulating shell (1) that is made of a flexible composite material and used for encapsulating the LED light string (2) by injection molding. The oxygenation pipe (5) made of a flexible material is detachably connected to the flexible waterproof encapsulating shell (1), and has at least one air-exhaust through hole arranged on the pipe wall thereof. The waterproof flexible LED light bar and the oxygenation pipe (5) are used cooperatively. Lighted by the LED light, bubbles formed by the oxygenation pipe (5) in the water enhance the lighting effect. The waterproof flexible LED light bar also can eliminate fixing devices in the water body and improve the water body environment, and is convenient for maintenance.Linvention porte sur une barre de lumière à diodes électroluminescentes souple étanche vis-à-vis de leau, laquelle barre comporte un tuyau doxygénation, et sur son procédé de fabrication.
