Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a pluggable tube lamp. Background Technology
[0002] Traditional plug-in lamp designs do not feature insulated heat sinks or other active heat dissipation structures. This results in the heat generated by the drive circuit during operation not being effectively dissipated, but instead being directly transferred to the inside of the lamp. The cumulative effect of heat accelerates the thermal fatigue of the filament metal material, thereby shortening the electron emission life. Thermal fatigue refers to the cumulative damage to materials caused by uneven thermal expansion and contraction under repeated or continuous temperature changes. In filament materials, thermal fatigue can lead to the generation and propagation of cracks, ultimately causing the filament to break.
[0003] Furthermore, traditional pluggable tube lamp technology relies on a phosphor material system containing mercury. An overheated environment increases the activity of mercury vapor, thereby accelerating the blackening of the lamp tube. Blackening refers to the process by which the inner wall of the lamp tube gradually turns black. This is mainly due to the chemical reaction between mercury vapor and other substances inside the lamp tube, as well as the evaporation and deposition of filament material on the lamp tube wall. Blackening of the lamp tube will further reduce the efficiency and lifespan of the light source, because the blackened lamp tube wall will absorb more light, reduce light output, and may affect the luminous efficiency of the phosphor.
[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

The heat dissipation lamp body 4 has a heat dissipation groove 41 in the middle. The lampshade 1 is fixedly connected to one end of the heat dissipation lamp body 4. The lamp plate 2 is located between the lampshade 1 and the heat dissipation lamp body 4. The insulating heat sink 3 is located between the lamp plate 2 and the heat dissipation lamp body 4.

[0026] In this embodiment, the heat dissipation lamp body 4 is an aluminum heat dissipation lamp body 4.
[0027] This application discloses a pluggable tube lamp, including a heat dissipation lamp body 4. A heat dissipation groove 41 is provided in the middle of the heat dissipation lamp body 4, so that the heat generated by the driver board 5 and the lamp board 2 can be quickly dissipated through the heat dissipation lamp body 4, effectively reducing the working temperature of the pluggable tube lamp, improving its stability and reliability during operation, and extending its service life. An insulating heat dissipation plate 3 is provided at the contact point between the lamp board 2 and the heat dissipation lamp body 4, which not only realizes the heat transfer between the lamp board 2 and the heat dissipation lamp body 4, but also blocks the risk of current leakage, effectively improving the safety of the pluggable tube lamp during operation.
[0028] Further, please refer to Figures 1 to 3 The side of the heat dissipation lamp body 4 is provided with a plurality of heat dissipation blocks 42, and heat dissipation grooves are formed between adjacent heat dissipation blocks 42, and the heat dissipation grooves include multiple grooves.
[0029] In this embodiment, the heat sink 42 is integrally formed with the heat sink body 4; the heat dissipation channel 41, together with the side heat sink 42 and the heat dissipation groove structure, forms a multi-channel heat dissipation path, which not only improves the heat dissipation efficiency, but also reduces the heat accumulation that may be generated during the operation of the pluggable tube lamp, thereby extending the service life of the pluggable tube lamp and ensuring the stability of the pluggable tube lamp during operation.
[0030] Further, please refer to Figure 2 and Figure 3 The lamp head 6 is provided with a positioning post 621 and a plurality of limiting blocks 622 at its end. A first positioning groove 411 is provided in the heat dissipation groove 41. The positioning post 621 is connected to the first positioning groove 411. The plurality of limiting blocks 622 respectively abut against the inner wall of the plurality of heat dissipation grooves.
[0031] In this embodiment, the positioning post 621 and the limiting block 622 are integrally formed with the lamp head 6. The positioning post 621 designed at the end of the lamp head 6 is tightly connected with the first positioning groove 411, achieving a precise positioning effect and ensuring the stability of the lamp head 6 during installation and use. At the same time, the setting of the limiting block 622 further enhances the stability of the structure. The limiting block 622 abuts tightly against the inner wall of the heat dissipation groove, and together they form a three-dimensional positioning constraint system, which effectively restricts the movement of the lamp head 6 in all directions, thereby greatly reducing the misalignment problem between the lamp head 6 and the heat dissipation lamp body 4 caused by external forces, and ensuring the reliable performance of the plug-in tube lamp under various environmental conditions.
[0032] Further, please refer to Figure 2 and Figure 3 The lamp head 6 includes a lamp head base 61 and a power supply compartment 62. The lamp head base 61 is snapped into the power supply compartment 62, and the power supply compartment 62 is bolted to the other end of the heat dissipation lamp body 4.

[0033] In this embodiment, the lamp holder 61 and the power supply compartment 62 are connected by a snap-fit method, which not only simplifies the installation steps and improves assembly efficiency, but also ensures a stable and reliable connection between the lamp holder 61 and the power supply compartment 62. Furthermore, when damaged parts need to be replaced, the operation can be performed easily and quickly without affecting the overall heat dissipation architecture, thus ensuring the efficient operation and long-term stability of the equipment. Further, the power supply compartment 62 is connected to the other end of the heat dissipation lamp body 4 by bolts, which not only facilitates disassembly and maintenance, but also provides high bolt strength, effectively resisting external impacts. The drive board 5 is located at the end of the power supply compartment 62, and the end of the power supply compartment 62 is located in the heat dissipation groove 41, which allows the drive board 5 to be well dissipated, avoiding performance degradation or damage caused by high temperature, and improving the reliability and stability of the plug-in tube lamp during operation.

At the same time, the connection between the copper pin 7 and the drive board 5 is simple and reliable, reducing the failure rate and improving the safety and reliability of the lamp.
[0034] Further, please refer to Figure 2 and Figure 3 Two guide blocks 623 are respectively provided on both sides of the power compartment 62, and a guide groove is formed between the two guide blocks 623. The drive plate 5 is connected to the guide groove.
[0035] In this embodiment, the guide block 623 is integrally formed with the power supply compartment 62, and the drive plate 5 is slidably inserted and removed through the guide groove, which can improve the installation and positioning accuracy of the drive plate 5 and reduce installation errors caused by manual operation. When maintenance of the drive plate 5 is required, the guide groove can shorten the disassembly and assembly time, which not only improves maintenance efficiency but also reduces downtime for inserting and removing lamps. In addition, after assembly, the guide groove can limit the movement position of the drive plate 5, preventing displacement caused by vibration, impact or other external forces, which helps to maintain good electrical contact between the drive plate 5 and the copper pin 7, while avoiding mechanical stress or damage that may be caused by positional deviation, thus reducing the failure rate.

[0040] In this embodiment, the second locking block 121 and the positioning block are integrally formed with the fixing seat 12. By opening multiple second locking slots 111 on the side of the cover 11 and correspondingly setting multiple second locking blocks 121 inside the fixing seat 12, the locking between the cover 11 and the fixing seat 12 is realized. This not only has a simple structure and is easy to operate, but also effectively prevents the cover 11 from loosening or falling off during use, thus improving the stability and reliability of the entire structure. Secondly, by opening a third positioning slot 112 on the cover 11 and setting a positioning block on the fixing seat 12, the cover 11 can be more accurately positioned on the fixing seat 12 during installation, which not only improves the installation efficiency, but also avoids errors caused by improper installation.
[0041] Further, please refer to Figure 2 and Figure 3 The fixed base 12 is provided with a connecting base 122. One end of the heat dissipation lamp body 4 is provided with a connecting hole. The side of the lamp plate 2 and the side of the insulating heat dissipation plate 3 are provided with clearance grooves. The connecting base 122 and the connecting hole are bolted together by fasteners. The clearance groove is used to avoid the fasteners.
[0042] In this embodiment, the connecting seat 122 and the fixing seat 12 are integrally formed; the bolt connection structure between the fixing seat 12 and the heat dissipation lamp body 4, together with the relief groove design, ensures that the lamp plate 2 can maintain a uniform pressure state even in high temperature environment, effectively preventing local overheating caused by poor contact, thereby improving the stability and safety of the plug-in tube lamp during operation.
[0043] Further, please refer to Figure 1 The lamp head 6 is provided with a third locking block 63 on each side, and the third locking block 63 is used to realize the fixed connection between the plug-in tube lamp and the mounting position.

This not only simplifies the installation process and reduces the installation difficulty, but also improves the installation efficiency, making the deployment and maintenance of the pluggable tube lamp more convenient.
