Abstract

A bent fluorescent lamp is assembled with a lamp that has at least three bent channel sections. And any number of straight sections connected to at least one of the many straight sections are warped. Assembled included With the process of straightening the glass tube with the resulting inner surface Being formed with a soft pre-phosphor film By heating, bending the two ends of the glass tube. Straightening to the S-shaped segment and twisting the center in Among the three straight parts that make up the S-shaped part, but Each part at both ends of the straight glass pipe, and bending the straight section at the center part of the straight glass pipe to a U-shape

Claims (10)

1. A bent fluorescent lamp consists of: a tube with at least three bent sections, each of which is made up of bends, joints, or both bends and joints; and several straight sections connected to the aforementioned bent sections to form a continuous discharge path, with at least one of the aforementioned straight sections being twisted; electrodes provided at the ends of the tube; and a phosphor film formed on the inner surface of the tube. 2. A light bulb consistent with claim 1, the aforementioned bulb shall consist of at least five bent channel sections, and one straight section of the aforementioned section shall connect one of the bent channel sections closest to the end to the remaining bent channel section, and the remaining straight section shall be twisted. 3. The light bulb conforming to claim 1 shall have two ends situated on the diagonal, and at least two of the aforementioned bent channels shall be positioned on either side of the diagonal in such a manner that they extend in a direction intersecting the diagonal. 4. In a light bulb consistent with claim 2, the surface on the inner side of a section of the aforementioned bent channel located at the center of the aforementioned bulb shall be partially flattened. 5. In a light bulb conforming to claim 3, the surface on the inner side of the bent section of the aforementioned bent channel, located at the center of the aforementioned bulb, shall be partially flattened. 6. The fluorescent lamp device consists of: a housing supplied with a base at one end; a baffle mounted on the other end of the said housing; a luminescent unit housed in the said housing, enclosed by the said baffle; and the said bent fluorescent lamp conforming to any one of claims 1 through 4, which is mounted on the said baffle and electrically connected to the luminescent unit. 7. Devices consistent with claim 6, the aforementioned fluorescent lamp shall have two ends of the lamp connected to the aforementioned separator with adhesive, and these two ends shall be separated by thermal insulation from the aforementioned separator. 8. An device consistent with claim 7, the aforementioned fluorescent lamp, shall have two ends of the lamp connected to the aforementioned separator by an adhesive in multiple sections along the circumferential direction. 9. The manufacturing process of fluorescent lamps consists of the following steps: softening a straight glass tube with a pre-formed phosphor film on its inner surface by heating; bending the two ends of the said straight glass tube into an S-shape; and closing the middle section between the three sections that make up the S-shape at each end of the said straight glass tube; and bending the middle section of the said straight glass tube into a U-shape. 10. A procedure consistent with claim 9, the torsion procedure shall consist of the arrangement of the aforementioned first and second straight sections, which together form the aforementioned S-shaped section, at their respective ends at the aforementioned midpoint in three dimensions in such a way that they do not lie in the same plane.
