Further, please refer to FIG. 2 , as another specific embodiment of the strip light provided by the present application, the driving element 22 is located at both ends of the printed circuit board 21, and the outer sleeve of the lamp tube 1 is provided with a cover for driving Polyethylene terephthalate stickers 6 for components 22 and wires 3 . Since the lamp tube 1 is a glass tube 800, and the lamp cap 11 is formed by softening and cooling the glass tube 800, the external material of the bar light is transparent glass material, and the driving element 22 and the metal wire 3 are not covered. Affecting the overall aesthetics of the light bar, a polyethylene terephthalate sticker 6 for covering the driving element 22 and the metal wire 3 is set on the outside of the lamp tube 1, which can realize the control of the driving element 22 and the metal wire 3 The coverage improves the aesthetics of the strip light. At the same time, the color of the polyethylene terephthalate sticker 6 is close to the color of the glass of the lamp tube 1, which further improves the aesthetics of the light bar.

Further, please refer to Fig. 1-Fig. 3, as another kind of embodiment of the bar light provided by the application, the outer cover of lamp tube 1 is provided with heat-shrinkable light-diffusing film 5, improves the light extraction efficiency of bar light , to achieve a better luminous effect.

Further, please refer to Fig. 2, as another kind of embodiment of the bar light that the application provides, the back side of printed circuit board 21 is provided with silicone glue 7, and silicone glue 7 is arranged in contact with lamp tube 1 The heat generated by the light-emitting element 23 and the driving element 22 on the printed circuit board 21 can be quickly transferred to the lamp tube 1, and the heat will be dissipated into the air after the lamp tube 1 contacts with the air. The silicone glue 7 can be used as a buffer to avoid the collision between the printed circuit board 21 and the inner wall of the lamp tube 1 .

Further, referring to Fig. 4, as another specific embodiment of the bar light provided by the present application, a limit notch 1111 is provided on the inner wall of the relief hole 111, and the outer wall of the molybdenum needle 4 has a The limit protrusion 41 of the notch 1111 prevents the movement of the molybdenum needle 4 when subjected to axial force, and improves the stability of the installation of the molybdenum needle 4 . The limiting notch 1111 can be formed by bonding softened glass to the limiting protrusion 41 on the molybdenum needle 4 and cooling.

Further, referring to Fig. 4, as another specific embodiment of the light strip provided by the present application, the lamp tube 1 and the lamp holder 11 are glass parts, that is, the lamp tube 1 is a glass tube 800; the lamp tube 1 It is integrally formed with the lamp holder 11. Therefore, when making the light bar, after the driving power board 2 is installed in the lamp tube 1, the position of the metal wire 3 is fixed by a jig; the openings at both ends of the glass tube 800 are heated and softened; After both ends are softened, clamp the softened part of the glass tube 800 and use the softened part to seal the opening of the glass tube 800, and make the softened part adhere to the metal wire 3, and make the metal wire 3 stick out of the glass Tube 800; the softened part is cooled to form the lamp cap 11. That is, the lamp cap 11 is a "part" of the lamp tube 1, the lamp tube 1 is set as a glass tube 800, and the glass tube 800 is softened and clamped to form a "lamp cap 11", and there is no need to separately set up the lamp cap 11, which further simplifies the structure of the bar light number of pieces. At this time, the softened glass material is bonded to the surface of the metal wire 3 and then cooled and solidified, so that the metal wire 3 can be stably installed at the "lamp holder 11" and the metal wire 3 can be fixed.

In the embodiment of the present application, please refer to Fig. 1-Fig. 4 synchronously, first make the driving power board 2 with driving element 22 and light-emitting element 23; Then metal wire 3 is connected with driving power board 2, and The driving power board 2 connected with the metal wire 3 is installed in the lamp tube 1; finally, the lamp caps 11 are arranged at both ends of the lamp tube 1; compared with the prior art, the light source board is installed in the lamp tube 1 first, and then the driving board is installed Installing in the lamp holder 11 and then fixing the lamp holder 11 on the lamp tube 1 effectively simplifies the assembly process of the strip light.

Please refer to Fig. 1-Fig. 3 synchronously, that is, the lamp cap 11 is a "part" of the lam...
