Zusammenfassung: | A semi-full helical luminous electronic energy-saving tube and an electronic energy-saving lamp using the tube are disclosed. The structure at the connection between the end of tube and the enclosure is a straight section. An inward bend of the straight section is achieved via an interface point between the straight section and the helical portion of the tube. The interface point includes a sharp, V-shaped 180° backward bend. By making use of the sharp inward bend, a sufficient space is left for the enclosure process. |
