Beschreibung
Zusammenfassung:	The present invention discloses a U-shape LED tube, comprising a U-shape tube body and light bars fixed inside the U-shape tube body. The U-shape tube body comprises two straight tube sections and one curved section, the curved section comprises two semicircle tubes, the two ends of the curved section are provided with shrinkage parts that are inserted in the straight tube sections, and the shrinkage parts are in fixed connection with the straight tube sections through ultrasonic welding. The curved section of the present invention is provided with shrinkage parts that are inserted in the straight tube sections, the outer diameters of the tubes of each part are consistent, achieving streamline aesthetic appearance; the shortcomings of tube body corrosion and light emission blockage due to fixing of light bar with adhesive glue in conventional LED tube are overcome through ultrasonic welding.
