Detailed ways

Referring to Fig. 1, the T8 type LED lamp of the present utility model is mainly composed of a lamp tube 1, a lamp cap 2, a light bar substrate 3, a driver 4, and a spring 5, wherein LED light sources are distributed on the light bar substrate 3. Fig. 1 only shows one end of the lamp tube on which the driver 4 is installed, and the other end of the lamp tube is basically the same as the structure shown in the figure except that no driver is provided.

As shown in the figure, the lamp tube 1 of the present invention is in the shape of a circular tube, which can be a glass tube or a PC plastic tube, which has the effect of light transmission.

The lamp cap 2 is tightly fitted on the end of the lamp tube 1, and its overall shape matches with the lamp tube 1. The lamp cap 2 is provided with a binding post 6. When in use, the binding post 6 is connected with an external power supply to input the mains alternating current. The driver 4 is arranged in the lamp holder 2, and it is used for converting the input commercial AC power to provide a stable DC power supply.

The light bar substrate 3 is arranged axially along the lamp tube 1 , and the output end of the driver 4 is connected to the light bar substrate 3 to supply power to the LED light source on the substrate 3 . In order to fix the light bar substrate 3 , the utility model connects one end of the spring 5 on both sides of the light bar substrate 3 , and the other end of the spring 5 is fastened to the inner wall of the lamp holder 2 . The connection between the spring 5 and the light bar substrate 3 can be implemented in different structures, for example, holes can be provided at both ends of the light bar substrate 3 , and the spring 5 can be hooked into the openings. In this embodiment, two ends of the light bar substrate 3 are respectively provided with protruding posts 7 , and one end of the spring 5 is fixedly connected to the protruding posts 7 . In different embodiments, the boss 7 can be realized in different ways, for example, the boss 7 can be integrally formed on the substrate 3, but as a preferred embodiment, the boss 7 is preferably a rivet, a light bar The base plate 3 is provided with a screw hole for the screw connection of the rivet, and the required protrusion structure can be obtained after the rivet is locked.

As shown in FIG. 1 , in order to make the installation of the utility model more convenient, the lamp holder 2 is preferably implemented in a split manner. Specifically, the lamp cap 2 is composed of a lamp cap cover 21 and a lamp cap cover 22. The lamp cap cover 21 is tightly placed on the end of the lamp tube 1. The lamp cap 22 is provided with a protruding buckle 8, and the lamp cap 22 is buckled by the buckle 8. The way of being tight to the inner wall of the lamp cap cover 21 is assembled and connected with the lamp cap cover 21 . The other end of the spring 5 is fastened on the inner wall of the lamp cap 21, and the inner wall of the lamp cap 21 is provided with a hanging hole 9 for its fastening. When installing, when the lamp cap 21 is placed on the lamp tube 1, This hanging hole 9 can also play a position-limiting effect. In addition, in order to make the installation of the driver 4 more convenient, the lamp cover 21 is provided with a supporting platform 10 extending to the inside of the lamp tube 1, and the end of the supporting platform 10 is provided with a vertical baffle 11, and the driver 4 is placed between the supporting platform 10 and the vertical baffle. within the space defined by the board 11. This space matches the overall shape of the driver 4, and the driver 4 is fixed in position in this space.

During specific assembly, first put the light bar substrate 3 with springs connected at both ends into the lamp tube 1, put the lamp cover 21 on, and then buckle the other end of the spring on the hanging hole 9 of the lamp cover 21, that is, The lamp bar base plate 3 can be fixed, and then the lamp cover 22 can be buckled into the lamp cover 21 to complete the assembly. When it needs to be disassembled, it can be operated in the reverse order.

After the assembly is completed, the spring can directly tighten the light bar, and the lamp head reacts on the light tube, so that the light bar is firmly tightened in the light tube, so that the light can be emitted evenly and normally. The heat generated by the light bar during operation can be transferred to the lamp head through the spring and further spread outward to achieve a good heat dissipation effect. Due to the use of the current special accessories and unique structure, which simplifies the assembly process and saves materials, the traditional T8 lamp must use professional machines to improve production efficiency, but the utility model uses special accessories and unique structure. Revolutionary improvements and changes have been brought about in terms of cost and heat dissipation.
