[0002] T5 lamp is a kind of fluorescent lamp, also known as fluorescent lamp, light tube, fluorescent tube, with a tube diameter of about 16 mm, and is a kind of low-pressure gas discharge lamp. The radar sensor and light source driver of the LED lamps currently on the market are independent of each other. However, due to the large size of the radar sensing module on the market and the small diameter of the T5 lamp, the radar sensing module cannot be installed inside the T5 lamp and can only be installed outside the T5 lamp, which increases the difficulty of disassembly and assembly of the T5 lamp and increases the production cost of the enterprise. In addition, independent radar sensing requires a radar sensing module and a corresponding driver, which is costly, further increasing the production cost of the enterprise.

[0003] How to design a T5 lamp tube that can add radar sensing to the inside of the T5 tube has become a technical problem that urgently needs to be solved in this field. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to deepen the understanding of the utility model, the utility model will be further described in detail below with reference to implementation cases and drawings. The utility model can be implemented in the following ways:

[0023] Reference Figure 1-4The integrated driver with radar sensing of the utility model comprises a light source driving board 1 with a plurality of electronic components 14, and a radar sensing module 2 is fixedly connected to one end of the light source driving board 1.

[0024] The radar sensing module 2 is welded to one end of the light source driving board 1 through the terminal 3; the upper and lower ends of the terminal 3 are provided with pins 31, and the upper and lower ends of the terminal 3 in this embodiment are provided with three pins 31. The light source driving board 1 is provided with a terminal fixing hole 11 for the pins 31 of the terminal 3 to pass through at the connection with the radar sensing module 2, and the end of the radar sensing module 2 is provided with a terminal fixing hole 21 for the pins 31 of the terminal 3 to pass through. When assembling, first insert the three pins 31 at the lower end of the terminal 3 into the terminal fixing hole 11 of the light source driving board 1, and insert the three pins 31 at the upper end into the terminal fixing hole 21 of the radar sensing module 2, and then fix them by welding.

[0025] The light source driving board 1 is provided with a through hole slot 12 for the light source board 4 to pass through on the side of the radar sensing module 2. The through hole slot 12 is provided with a pad 13 for welding the end of the light source board 4 on the other side relative to the radar sensing module 2, and the pad 13 is located at the bottom of the light source driving board 1. The pad 13 is specifically 3 solder points, the number of which is the same as the electrical connection point for the light source board 4. Generally speaking, the connection end of the light source board 4 needs to be welded and fixed to the front of the end of the light source driving board 1, but because the gap between the radar sensing module 2 and other electronic components 14 is narrow after the radar sensing module 2 is installed, the welding operation area of ​​the light source driving board 1 used to fix the end of the light source board 4 is greatly reduced, which greatly increases the difficulty of the operation. The design of the through hole slot 12 can perfectly solve the above problems. During assembly, the connection end of the light source board 4 can be passed through the through hole slot 12 from the front of the light source driving board 1, and then turned over to weld with the welding part 13 on the back of the end of the light source board, which is simple and quick to operate.

[0026] A T5 lamp tube comprises a glass tube 5, wherein a light source board 4 and the above-mentioned integrated driver with radar sensing are arranged inside the glass tube 5, and lamp caps 6 are arranged at both ends of the glass tube 5.

[0027] The light source board 4 described in this embodiment is a flexible board, that is, a flexible light source board, so that the light source board 4 can be more flexibly connected to the light source driving board 1. The flexible light source board is bonded to the inner side of the glass tube 5 by heat-conducting silicone.

[0028] The lamp holder 6 is provided with a plurality of breathing holes 8 on the end face on the side where the lamp pins 7 are located. Four breathing holes 8 are provided in this embodiment. The breathing holes 8 can enhance the air convection inside and outside the lamp tube and enhance the heat dissipation. The outer end face of the lamp holder 6 is concave in the middle of the two lamp pins 7 to form a recess 9 which can increase the creepage distance between the two lamp pins 7, thereby enhancing the safety performance of the lamp tube. In addition, the lamp holder 6 of this embodiment adopts a short lamp holder design, and shortening the length of the lamp holder 6 can increase the light-emitting surface of the lamp tube. The lamp holder 6 of this embodiment is not directional and can be installed quickly.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
